THE imYNCIIOPIIORA OF AMEIiICA, NORTH OF MEXICO.
By John L. LeConte, assisted uy Geouoe II. IIonx.*

PREFACE.

The task that I have attempted to perform in tlic present memoir, is a
very dirticult one, and I feel tliat it has been accomplislied very imperfectly.

It is, namely, from the study of the very small material represented in
the fiuina of temperate North America, to induce entomologists to investi-
gate those Coleoptcra, which have been heretofore classed as Curculionidie
and some allied, but ill-defined families, from a completely new standpoint,
whereby they become isolated from all other Coleoptera.

The characters which render necessary this isolation of the Hhyncho-
phora have been already exposed by me in some sliort memoirs,! and
their value has been recognized by several systematists of excellent ai)illty,
although not to the extent to which I hope the present effort will render
them acceptable. These characters are mainly to be found in tlie form of
the basi-lateral elements of the head and prothorax on the under surface of
the bodj', and will be detailed in the Introduction.

By these peculiarities of structure, as well as by their food, tlio Rhyn-
chophora ai'c restricted to a more uniform type of organization than is exhi-
bited in the n<irmal Coleoiitera; but at the same time being represented by
an immense number of species, the generic modifications are very varied.
The difficulty of tabulating these generic forms in a manner to exhibit their
relations to each other is therefore greatly increased.

I have previously expressed my opinion that the Rhynchophora, being
the lowest type of Coleoptera, arc tlierefore geologically the oldest. Re-
garding then the fixity of insect types, as shown by the resemblance of an-
cient forms to those of the present time, the imiformity in food and manner

of life, and the iinmenso uumbor of gencm in U»is complex, with which we
are deiilini,', wc Imve ii right to expect thiit there Avill be ii proporlionnlly
larj^er .siirvivul oriiii('lmnu;(Hl (U'sceiuliints of those species or scneni wliicli
were llrsl iiilnxliu'cd. \V'e will, theniore, hav(^ ii more pert'ccl series of
conu(!ctiiii5 forms ihiin ctin he foiin'l In other orders of insects, whoso
melliods of life expose them to llie inHiiences of destruction or modillcation
by exierniil eircumsliuiecs.

Nevertheless, the arrangement which I luivo adopted, will show in the
larger groups or tribes, a dominance within the liuiits of each trib(> of one
typical modilication of structure, with vni'iutions in tin- direction of modi-
fications which become dominant, and definitive in other tribes.

ll thus comes to pass that, neglecting the essential clianuMersof the tribe,
to which the species maj' propcily belong, the delinitiou of the genus will
approximate in language very closely to that of some otlier genus, belong-
ing to a very distinct pait of the series.

In otlier words, the giMicra belonging to several tribes will agree Avith
each other in similar characters of less value than the tribal characters.

What I have just said regarding gener't is equally true in respect to
species. The form, color and sculpture in many instances are repeated in
tribes which from their geographical distribution and method of life can-
not be sui>posed to have anj' immediate genetic derivation. Instances of
this kind of resemblance will be mentioned both in the Introduction, and
in the body of the memoir.

1 have no theory to i)roi)ound regarding this very C(miplex system .;'
cross resemblances. They are certainly not the result of mimicry, and pro-
bably not of natural selection, or any other name of an idea which has yet
been suggested. A deeper insight into the phenomena of organic nature,
which may, perhaps, be acquired by our successors would give us a more
reasonable explanation of these resemblances.*

My best thanks arc due to my excellent collaborator. Dr. G. II. Horn,
for his careful study and classification of the himily Otiovhynchida>, cer-
tainly one of the most ditficult among the llhynchophora, and next to the
genuine Curculioiiidw, the largest. I also owe my kindest acknowledg-
ment to Mr. G. W. Belt'rage, for a large series of specimens from Texas; to
Messrs. II. G. Hubbard and E. A. Schwarz, for very full scries from Michi-
gan and Florida; t'^ the ]\Iuseum of Comparative Zoology of Cambridge for
the loan of the Ziniuicrmann collection, mostly from the Southern States;
and to Messrs. E. P. Austin, W. Jiilich, and Prof. C. V. lliley for large
sets of specimens from various parts of the country. Other friends have

INTRODUCTIO:Nr.

Rhyncliophorous Coleoptera aie those in which tlic posterior liiteral
elements of the hciul* and prothoraxf coalesce on the median line of the
under surface of the hody, so as to unite by a single suture.

To the first of these characters there is no exception in the wide ranixe
of the existing Coleopterous insects ; to the second tliere are two iiotaMe
discrepancies. The first is Nematidiam.X commonh" classed with the
CoJydiidie, the other is the genus Cos.typhit.!>,'/, which has been considered
as belonging to the Teiiebrionidce, from the other members of which it
differs, not only by the structure of the under surface of the prosternum,
but by other characters, which require future study for a proper ai)precia.
tion of their imporlain-e.

I might rest llic definition of the Kiiynchoi)hora at this point, and jiro-
ceed to indicate the ditterent series and families into which, accordinu' to tlu'
system I have developed, these insects should be divided, but before doing
so, there appear to me certain relations between the members of this sub-
order, which are well worthy of attention; and certain cliaractcrs which I
have not had time to investigate fully, but which are indicated for tlu'
guidance of tliose, who will in future adopt the views herein set forth.

Tliere are also certain characters conunon to all, or nearly all Rhyiichoph-
ora, most of which I have mentioned in the two essays cited below,!
but which for convenience may be here briefly recapitulated :

1st. There are no soft, larval, or imperfectly chitinized forms, or forms
with short elytra, exposed wings, or greatly multiplied antennal joints,
such as are of frequent occurrence among the normal Coleojjtera.

2(1. There are none in whicii the side pi(>ces of the iirothoiax are separated
bj' suture from the pronotum, au'l very few in which even the lateral
margin is indicated; in many the prosternal sutures are distinct, liut in
some even these are obliterated.

3d. In none are the front coxal cavities open posteriorly, though in some

INTRODUCTION".

llio t'onu'oiis i)Iate fonncd hy llie coiilcsceiir'C of tlio iJosterior liilcral
elements (epiiueru) is veiy narrow ; and ii3 other cases ' Barii*, &c. ) tlie
posterior part of tiie iirosternuni is tliiekeiieil and overlies the suture on thn
median line, liul without coming into contact with the nii'soslernum.

4lh. The ventral segments never exceed live in number, and the first
and second are usually larger and more closely connected, fre(iucntl\' even
connate, with partially obliterated suture; the fifth is sometimes k)nger
than the fourth, sometimes about equal to it.

."ith. When there is any appreciable dillerenco Ixjtwcen the sexes, it is
usually manifested by a greater elongation of the beak of the 9 ■?. indi-
cating its use as an accessory organ of generation, for making the jjcrfoia-
tion in which tlie egg is subsequently placed by the soft oviiiositor, and
pushed down by the beak.

(ilii. The other sexual difTerence is in the addition of a small dorsal (or
anal) segment to the ,J^c5^; this character is, however, not oiivious in
several ftunilics, the morphological representative of this anal segment
being completely retracted and covered by tlie pj'gidium. In others this
segment is visible only from heneatli, simulating, therefore, a sixth ven-
tral.

7th. The very rare occurrence of articulated movable spurs at the end
of the tibia'; it is seldom, indeed, that more than one fixed mucro occurs,
and in the species in which the tarsi are inserted laterally near the tip, this
mucro becomes frecpicntly ehmgated and curved ; the outer angle of the
tip is in these instances (pnte ofien i)rolonged into a curved digitation, like
the terminal tooth of the front tibite of some Scaritini, of the family
CanibuUe.

8th. The head is most fnjqucntly prolonged in front of the eyes, forming
a bei>k, which is usually narrower tliau the front, and fre(iuently very
sleiuler. A llattcned prolongation, similar to a beak, occurs in some genera
of Ciiciijidp, PjjthidtK and UMemcvidue, but not elsewhere in the normal
Coleo[)tera.

Dth. In the vast majority of species the labrum is wanting; in some
Scolytidic it is feebly develoi)ed. bu' is present in normal form only in
Rhiti'iniiiccrida' and Anihribiihe.

lOtli. Except in RhinonuiceridiB and Anthribidat tlie jialpi are short and
rigid, with the joints diminishing in size; in those families they are slender
and flexilde, as in normal Coleo|)tera.

1 lib. In those genera in which the hind tibiic aretruncat(! and margined
at tip, forming u surface called a corbel, this surface may be glabrous or
scaly. In normal Coleoptera they are always glabrous, and in lli/poccph-
ahm alone they are densel}' clothed with hair.*

Vilh. A peculiar ridge on the inner surface of the elytra, into which th(!
asceniliiig margin of the metathoracic e])imera and ventral segments fit,
giving great firmness and solidity to the hinder part of the body. This

ridiio is rarely wantinji; .ami is represented amonj^ nornuil Coleoptcni, so
f'iir as I have examined, only in eeriaiu IhipreHtidiv.

These characlers taken collectively, in addition to tlie two fun<lamental
defininjjj chafaclers first mentioned, indicate a profound diHereneo in or-
ganization, wliieli isolates the Khynchophora I'rom ail other Cohsoptera.
From this isolation results the necessity ol' classifying them upon oilier
characters than those which arc found useful in defining series and fami-
lies in the normal ('oleoi)tera. TIk; great resemblance in general ajipcar-
ance of the insects of this type, and the endeavor to consider them as only
a family in the whole series of (^)leoptera, lias caused the characters used in
this memoir to be either undevvalued or overlooked. I believe, how(!ver,
that when attention is directed to them, and to certain other characters,
which I have not hadtinu; to fully investigate, the arrangement of these in-
sects into natural groups will be found as simple and intelligible as that of
the normal (.'oh.'oplera.

Among the investigations which yet remain imperfect, I would mention
as sjiecially deserving of atteiuion, the stridulating organs. Then; are in
some genera spaces on the inner surface of tlu! elytra, which have a pearly
lustre, and which are probably capable, by friction against the ascend-
ing margin of the ventral segments, of producing a sound. I have; men-
tioned these undcu' the genus LinfroiiotKx, of the Phi/tono/aini, but they an!
present in many genera of other trii)es, and in fact, the Conotracheli nud
many others are known to emit a siiueaking sound.

The homologies of the parts of the head, by reason of which the front por-
tion becomes extended into a beak, and the basal pi(!cc on the under surface
(which separates the gular sutures in normal Coleoptera) disappears, are also
worthy of attention; so too are the larvse, with the view of discovering
some general characters in which they differ from those of other Coleojitera.

A more careful study should also be made of the antcnnic of the Htoh/-
tidit, by speciuKiiis mounted in Canada balsam, so that the homologies of
the joints of the funiclc, when tli(!y disappear may be ascertained. The
subject, as treated in this memoir, is, I may say, barely sketched, and will
yield to others, who may devote labor to it.not only the correction of erro:s
I have made, but many new truths and generalizations greater in value
than those to Avliich I have attained.

The afTlnities of the families of I{liynclio])hora among themselves, and
their res(anblances to various series or families of the normal Coleoptera
remain to be indicated.

The typical llhynehophora, Curculioniihr, while exhibiting in flu; ill f-
ferent tribes characters which are nion; individualized and combined with
special structures in the other f iinilies, occupy a central position around
which the latter may be gnuipcd.

The llhinomaceriiUf, liy the presence of a labrum and flexible paljii, as
well as by the general form of body.and 11 -jointed, nnn genicidate anienniu,

15y tlie gnulual obsolescence of the deciduous mandibular appendage, and
tile scar, wliicli is its natural conse(iuent, tlie Otiorhynchhliv i)ass almost in-
seusil)ly into the CwrcuUonhlu'. Tlie last named family through the Eri-
rhinhu is aflUiated with the BhyiicJu'tidm, and through the Barini with the
CdUdicln'fliP and GonsoiiidiB.

The Ilylastea group of the Seolytiditt shows strong affinities Avitli the Cos-
Honidie, and a slight reversion towards the Cryptorhynchini of the Curcu-
lionidce.

The Brenthidie arc isolated, and indicate a relationship which is neither
of atlinity or analogy, but rather of contemporaneous origin with Jfypocvph-
(ilidw, BhysodidiV, Cti.pendw, and perhaps sf)ine other families of normal
Colcoptera, which have been yet imperfectly stuitied. Nevertheless, by
certain abnormal genera, not occurring in our fauna, they exhibit a re-
semblance in some characters to the sub-family Platypodidm of the Scoly-
tidie, and connect both, by their resemblances with the ColydiidiB of the
Clavicorn series of normal Coleoptora.*

Some of the Scolytidm in form and general appearance resemble the feebler
groups (ChoraguH, &c.) of the AiUhribidm, but the characters of the latter
are so peculiar, that they must l)e viewed as a synthetic type, combining
resemblances to very diverse series. The form of the mentum, if I have
interpreted it correctly, is found only in the Adeiihaga (Amphizoa), while
the great sexual dilfcrences in the length of the antenuic occur only in the
Cerainbycida: The well developed labrum, filiform flexible palpi, straight,
ll-j(.)inted anlei^nse, and epipleura' indicate a higher organization than is
found in other Khynchophora. The complete consolidation, without su-
tures, of the elements of the under surface of the head and prothorax, indi-
cate a progress along the line of true Ilhyncliophorous development, upon
which I have based the two fundamental defining characters. The pro-
gress in this instance has been carried so far as to cause tlie disappear-
ance of these very characters. If any resem])lance to the normal Colcop-
tera could be seen to replace them, the Anthribida; would be removed, as
has been done witli the Bruchidw, to some other part of the system. But
this is not the case, and they must remain, therefore, as the expression of
the most perfect development thus far attained in the lllij'nchophorous

tyi>e.t.

The classification here adopted is simply that set forth by me in the
memoir:]: above cited, which was read before the National Academy of

criticism, that I have failed to identify them Avitli tliose already in the books.
In explanation of this, I would say that I have defined the tribes, genera
and species, in many instances, bj' characters, which have been unnoticed
or neglected by previous investigators ; and finding that quite frequently,
species, liaving a strong external resemblance, dijlcred by structural charac-
ters of great moment, I did not feel 'Aairanted in applying to them names
given to species, whicii agreed with them in tlio outline, vcstiture and
sculpture of the larger parts of the body, but which have been described
from other zoological districts. It will be easy, by the aid of the structural
characters which I have given, to identify my species with the types exist-
ing in European cabinets. I would rather that those I have named would
sink into synonymy, than that, in the present condition of science, I should
appear to teach false ideas regarding geographical distribution, which, when
carefully studied, must give us important aid in attaining a knowledge of
the causes and development of the existing order of things.

RIIlNOMACERIDvE.

Family I. RHINOMACERID^.

Mentiim trahsverse, small, emarginate in front, supported on a very
broad gular peduncjle ; ligula and pnlpi small.

Maxilla; exposed, lobes short, f;iliate at tij), inner one very short ; palpi
4-jointed, cylindrical, well developed. Mandibles flat, curved, acute,
toothed on the inner side.

Antennteinsertedatthesideof the beak near the end, ll-joiated, straight,
first joint a little stouter than the second, but not longer, joints 2 — 0 nearly
equal, 7 and 8 a little shorter and broader, ^ — 11 forming an elongate loose
club, the la.st joint oval, pointed, divided transverselj' near the tip. Ail
the joints are sparsely pilose, and those of the club are covered with sensi-
tive surface.

finely granulated ; beak as long as the prothorax, rather flat, narrowest
about the middle, wider at base and tip; Avithout antennal groove.s. La-
brum distinct.

distinct, widely separated, parallel in front, then curving inwards, and at-
taining the coxal cavity about the middle of its outer margin ; coxal cavi-
ties rounded, confluent.

Mesosternum flat, ivjinted behind at the middle, coxal cavities rounded,
confluent ; trochantin large ; epimera transverse, oblique, attaining the
trochantin.

Metasternum rather long, side pieces narrow, slightly dilated externally
in front.

This family contains a few species inhabiting the northern temperate
zone, and depredating on the male flowers of coniferous trees ; in which
the eggs are deposited. As I have observed on a former occasion, this
family is a synthetic or undifferentiated type in which the Rhynchophora
make the nearest approach to the lower Iletemmera ; it is therefore inter-

Pubescence long and coarse :

Prothorax not longer than -wide 1. pilosus.

Prothorax longer than wide 2. elongatus.

Pubescence short and fine 3. comptus.

The (^ dirters from the 9 by the front tibise being longer and slightly
curved inwards, and the beak longer, more slender, and less dilated, at the
tip. The tufts of hair at the middle of the third and fourth veutnil seg-
ments of the 9 are also present in our species.

The anal segment characteristic of the J^ of the second series of Rliyn-
chophora also exists in Rhinomacer, but is not prominent, and is almost
concealed by tlie last dorsal segment, which is rounded at tip.

1. R. pilosus, n. sp.

Brown or blackish ; antennae and legs paler ; pubescence long and coai*se.
Beak punctured and substriate, head densely punctured. Prothorax us
wide as long, densely and strongly punctured, sides rounded. Elytra con-
vex, parallel, elongate, coarsely punctured. Length 3.6 mm's ; .15 inch.

Lake Superior, Virginia, California ; four specimens.

2. B. elongatus, n. sp.

Blackisli witha slight brassy tinge ; antenna; and legs brown ; pubescence
pale brown, long and coarse. Beak with the outer half pale ; sculptured
as in the preceding. Prothorax a little longer than wide, very densely
punctured, sides very slightly rounded. Elytra rather narrower than in
the preceding. Length 3.6 mm's, .15 inch.

Pennsylvania four specimens. Two are dark colored ; one dark with
pale elytra, and one entirely pale brown.

One 9 from Canada, with pale brown elytra has the form and sculpture
of the other four, except that the prothorax is scarcely at all rounded on
the sides, and is less densely punctured, and the elytra still more elongated.
It may indicate another species, but I am unwilling to designate it as such
without more specimens.

3. R. comptus, n. sp.

Form and size of B. pilosus ; blackish with a distinct brassy tint, clothed
with short wliitisli hair. Head and beak as in the other species. Pro-
thorax as wide as long, rounded on the sides, more finely and densely punc-
tured. Elytra more densely and rugosely punctured. Stem of antenaae
pale brown. Length 3.6 mm's ; 15 inch.

Family IT. RHYKCHITID^E.

Mentum small, subqiuulratL', Mui)portL'il upon a long narrow gular iwdun-
cle ; ligula prominent, small, palpi short.

MaxilUe exposed, i)alpi short, rigid, as in Curculionidsc, 4-jointed.

Mundibles toothed on the outer and inner side ; capable of great lateral
extension ; in repose the outer apical tooth on each projects forwards, so
that two small acute teeth seem to jirojeet from tlu; mouth.

Antenme inserted at the sides of the beak, in position varying according
to the genus ; 11-jointed straight, first joint not elongated, and scarcely
stouter, 2 — 8 slender, 9 — 11 broader, forming a loose club, and covered with
sensitive surface.

Head prominent, not deflcxed, ej'es rounded finely granulated ; beak
slender, varying somewhat in fonn according to the genus.

Protliorax truncate before and behind, convex, prosternal sutures not
visible, coxal cavities rounded, somewhat transverse, with a distinct fissure
at the outer side margin : distant in Pterocolus, confluent in other genera.

Mesosternum flat, acute behind in all but Pterocolus, and with the side
pieces normal iu form and diagonally divided ; in that genus they are tnm.s
verse, prominent, apparently undivided, and ascend between the prothorax
and humend angle of the elytra, suddenly declivous and excavated in front
for the protection of the legs ; coxal cavities approximate, except in Pten>-
colus.

Metasternum rather long, with narrow side pieces ; shorter with wide
side pieces in Pterocolus.

Elytra separately rounded behind, exposing the pygidium in some gencni ;
conjointly rounded, and covering the pygidium in others, epiplcunc dis-
tinct ; submarginal fold on inner face short and straight.

Abdomen with five free ventral segments, nearly equal in length, sepa-
rated by straight sutures, intercoxal process acute except in Pterocolus :
(J* without additi(mal anal segment, pygidium in both sexes triangular, de-
flcxed ; sides of segments not forming an acute edge, and not fitting into a
lateral groove of the elytra.

Anterior coxaj usually conical, contiguous, and prominent ; smaller,
rounded and separated in Pterocolus.

Middle coxae similar to the front ones.

Hind coxae transverse, reaching to the margin of the elytra, or nearly so.

Legs slender, rather long, tibiae truncate at tip, -with small terminal
spurs ; tarsi brush-like beneath, 4-jointed, third joint broad deeply bilobed ;
claws bifid, or acutely toothed.

Though nearly related to the preceding famih', these species arc readily
distinguished by the absence of labrum, and the peculiar form of mandible,
which recurs again only in Desmoris, an Erirhine genus of Cureulionida?.

While in RhinomaceridsB a relationship to nonnal Ooleoptera is seen in
the presence of a labrum, and better development of maxillary palpi, a

similiir tendency is evinced in the Illiyneliilidte by the distinct cpiplctirre.
In tl>c anonialous genus Pterocolus moreover, tlic prothomx is distinctly
and acutely margined at the sides, and excavated beneatli, so ns to form a
large cavity for the reception of tlie front and middle legs. This character
is seen in no other Rhynchophorous insect, and would almost warrant its
reception as a distinct family. For the present however, I prefer placing
it as a sub-family.

Subfamily I. KlIYNCHITIDiE.

The distinctive characters of this 8ul)-family have been irainted out, but
may be briefly resumed as follows :

Body rather elongate, or pyriform, front and middle coxse contiguous,
conical, prominent. Prothorax without side margin, not excavated be-
neath. Mesotborax with side pieces diagonally divided, epimera not ascend-
ing. Metathorax witli narrow parallel .side pieces.

Our genera are as follows :

Pygidium covered by elytra.

Elytra punctured irregularly AtlLETES.

Elytra striate EUGNAMPTUS.

Pygidium exposed, elytra with striiB of punctures, RHYNCHITES.

EUQNAMPTUS Sch.

The species of this genus are more slender in form than the other mem-
bers of the family, and the legs are longer and more feeble. Acccjrding lo
the punctuation of the head, prothorax and elytra, the Bpecles may be
readily recognized :

Elytral interspaces very narrow 1. striatus.

Front not channeled.

Head feebly punctured, narrowed behind 2. angustatus.

" " not " " 3. coUaris.

1. Eu. striatus, n. .sp.

Elongate, black, clothed with erect black hairs, head and i)rothorax red-
dish yellow. Beak black, coarsely punctured, distinctly carinate behind
the antennae, which arc inserted about the middle and are long and slender ;
front sparsely punctured, obsoletely channeled. Prothonix longer than
wide, sparsely coarsely punctured ; dorsal line deep, abbreviated at each
end. Elytra with stria; composed of deep transverse punctures closely
placed ; interspaces narrow, each with a row of disUmt but distinct punc-
tures. Length 4.7 mm's ; .19 inch.

Of twelve specimens before me all seem to be 9, and differ from those
of the preceding siM'cies only by having the head behind the eyes cylindri-
cal and not narrowed. It may possibly be a dimorphous form of Ku.
nngustdtun.

4. Eu. puncticeps, n. sp.

Of the same form as coll<irii>, testaceous clothed with erect hairs. Beak
rather stouter less deeply sculptured, front obsoletely channeled, head
coarsely and sparsely punctured, cylindrical not narrowed behind. Pro-
thorax coarsely punctured, feebly channeled. Elytra with striic composed
of approximate punctures, interRpaces wide flat, each with a row of very
small distant punctures. Antennas extending to the base of prothorax,
stoutfr than in the other species. Length :5.(5 mm's; .1.') inch.

Illinois, Mr. B. D. Walsh ; Georgia. I have seen but two $ of this
species ; it is easily recognized by the stouter antenna;, and more uni-
formly sculptured beak, whicli is free from the impressions and lines seen
in the two preceding species.

5. Eu. sulcifrons Gyll., Seh. Cure, v, 343.

I refer to this species, a (J* from Texas, sent by Mr. Belfrage. It is of
exactly the same form and sculpture as Eii. tuirju^latu.^, but the eyes are
less prominent, more as in the 9 of t'^'^t species, and there is a fine but dis-
tinct frontal channel ; the head is gradually and distinctly narrowed be-
hind the eyes. The color is testaceous, with a lateral blackish viita on the
elytra gradually becoming broader behind ; an extension of this dark color
would give the appearance mentioned by Gyllenhal, in whose specimen
the elytra were blac'' with a blue reflexion, and pale piceous towards the
base.

3. R, mexicanus Gyll , Sch. Cure, i, 227 ; Chevr., Col. Mex. 108.

I refer to this species one specimen from Arizona, very similar to 11. hir
tus, but of a blue color ; the beak is rather shorter and broader, anil slightly
dilated at tip ; the two slrist towards the base are equally apparent, and the
front is similarly channeled. The head and prothorax are somewhat less
coarsely punctured, and the eljtral stria; are more evident, and composed
of rather larger punctures. The difl'erences, except in color and form of
beak, are not obvious ; the former may be variation, and the latter is.
perhaps, sexual.

tured ; the beak is also longer and more slender. I have one specimen of

punctured.

Sub-family II. PTEROCOLIDiE.

A single species constitutes this sub-family. On account of the anomal-
ous characters its place in the series of Rlu'nchophora has been changed from
time to time, without very satisfactory results. The latest authoritj% Lacor-
daire, deceived by the broad form of body, and ascending side pieces of the
mesothorax placed it in the neighborhood of Coutorhynchus. A study of
the mouth organs, as well as the antennie, shows that it is allied to Auletes
and Rhynchites, while the other differences require it to be received as a
very peculiar and distinct type.

It differs from the genuine Rhynchitida; by the antenna; inserted much
nearer the eyes, which are suddenly but not deeply emarginate in front.
The side margin of the prothonix is acute and well defined, and the under
surface, with the anterior part of the mesothorax. is excavated, forming a
large cavity for the reception of the front and middle legs. The elytra are
sculptured with wide shallow grooves, which are confusedly punctured ;
the epipleuraj are distinct ; the tips are widely dehiscent and separately
rounded, exix)sing parts of three dorsal segments, all corneous and densely
punctured Front and middle coxiE small, rounded, widely separated, not
j)ronunent ; posterior coxie separated, transverse, intercoxal process broad.
Tibiie with two distinct apical spurs, tarsi dilated, claws appendiculate.
Ventral segments short ; pygidium less convex in the ^f, and strongly in-
flexed. Side pieces of mesosternum transverse, solid, ascending between
the prothorax and elytra. Side pieces of metasternuni wide.

Legs stout, tibia; serrate on the inner side, armed at the tip with two
strong hooks, which represent the spurs in the two preceding families ;
tarsi dilated, brush-like beneath ; third joint deeply bilobed ; claws con-
nate at base.

A family containing but few genera, with less than 200 species, distribu-
ted mostly in the tropics.

This family contains but a small number of genera, all confined to the
Eastern continent, e.-cep' ThecententiiH which is restvicted to the interior
parts of the United States, extending i.ito Texas and eastward to Illinois.
It forms a tribe distinguished from other Byrsopidiu by the peculiar con-
forniation of the prosternum, which forms a triangular plate in front of the
coxie.

THECESTERNUS Say.

I have described (Proc. Acad. Nat. Sc, 1856, 18) what I at that time
believed to be six species of this genus, in addition to the one described by
Say. Subsequent investigation with more abundant material has raised
some doubt in my mind as to the validity of the .specific differences which
I then observed.

It is quite evideiil that tliere are several species, but it is found quite im-
possible to define them. There are all gradations from specimens ( T. huine-
raliK) in which the humeral processes are fully one-third as long as the
prothorax, to others {T. morbilloKUK) in which the elytra are truncate at
base, and the humeral angles only slightly prolonged.

It may be regarded therefore us a genus In which the originally distinct
species are becoming effaced by mixture.

The specimens which I collected in Kansas were found under dried

buftalodung. I have since received several individuals from Illinois,

Texas, and Missouri ; upon one of the latter is this note, made by Mr. C.

V. Riley : "Cutting off blossoms of grapevines in May ; also beaten from

Carya."

OTIORHYXCHID^.

Famiiv y. otiorhy:n^chid^.

Mentuin variable, sometimes large, filling the giilar emarginatlon and
without peduncle, or small exposing the maxillce and ligula and with dis-
tinct peduncle.

Labial palpi very rarely visible and then very short.

Mandibles short, stout, pincer-like, verj- rarely slightly scissor-like, and
in one instance (Dirotogiuithus) slightly' laminiform and prominent. Ante-
rior face with a distinct scar freciuentlj- borne at the tip of a slight process.

Antenna* inserted at the sides or top of rostrum always in front of middle
and usually near the tip, geniculate, 11-jointed (except in Affraphns), the
last three forming a compact club with distinct evidences of the sutures.

He;ul moderately prominent, nirely {Af/dsphcerops) deeply inserted ;
beak variable, never long and slender. Scrobes well defined, except in
OtiorhyneJdni, and receiving the first joint (scape) of the antennte in repose.

Prothorax of variable form, apex usually truncate; rarely slightly pro-
longed over the head, base truncate, arcuate or bisinuate, post ocular mar-
gin either truncate or with ocular lobe more or less developed, sometimes
with stiff fimbriae. Anterior coxtc contiguous (except in Payidelefejun).

Mesosternum short, oblique or horizontal, rarely (Coleocci'U.i) protuber-
ant ; middle coxa; narrowly separated ; side pieces variable, never attaining
the coxal cavity.

Metasternum variable, short in Division I, usually long in Division II.

Elytra concealing the abdomen entirely from above, without trace of
epipleuriE but with inflexed fold on their inner side.

Abdomen with five ventral segments, the first two connate, the others
free. Intercoxal process variable.

Legs moderate ; femora very rarely decidedly clavate ; tibia; straight or
feebly arcuate, usually mucronate at tip and rarely with small spur-like
processes (certain Oliorhynchi)u). Claws fixed or moveable, always simple,
never toothed.

The males of all the species have the pygidium divided, so that there are
eight doi"sal segments, while in the female there are but seven.

This family contains all those genera in which the mandibles arc provided
in the pupa stage with a deciduous piece of varying form, usually elongate
and slender, sometimes falcate and acute or short and conical. In the early
life of the imago these pieces are lost (although specimens occur in which
one, sometimes both are preserved), and the place of their attachment is in-
dicated by a scar which is usually on the face of the mandible but frequently
borne at the tip of a process of varying length. The form of the mandible
itself without reference to the scar, indicates the occurrence of the deciilu-
ous piece. When the mandibles arc acute at lip and one overlaps the
other by an edge more or less acute, no deciduous piece ctm be expected.
Its occurrence may always be looked for in those in which the mandibles
meet with a broad surface and whose function is rather that of crushing
than cutting. Bracfij/cerus, Sttones, Alophut and all the Mecorhynchi are

instances of the former, while Cyphu», Entimus, Lepioj)s, Ophryastex,
Tanymecus, etc., illustrate the latter form.

The family Otiorhynchidie as defined by Dr. Leconte (American Natu-
ralist, 1874, p. 396), has but little to do with the tribe of the same name as
restricted by Lacordaire (Genera vi, pp. 20 and 144), as it includes not
only the greater portion of the Adelognathes, but also several tribes of
Phanerognathes in the system of tlie latter author.

In examining the under side of the body two forms of construction are
found, by means of which this large family may be divided into two
primary sections.

First. Side pieces of mesosternum very unequal, the episternum
larger and attaining the elytral margin, epimeron usually small,
sometimes very small. Metasternal side pieces never very wide,
^, generally very narrow or entirely concealed by the elytral margin,
\~ anterior end never broadly dilated on both sides.

Second. Side pieces of mesosternum diagonally divided and equal
or very nearly so, episternum distant from the elytral margin, sepa-
rated by the epimeron. Metasternal side piece moderately wide,
dilated at its anterior end with an acute process of greater or less ex-
tent projecting inwards between the mcsosternal epimeron and the
body of the metasternum.

The accompanying wood cuts have been drawn natural size from
(1) Eupaffoderes speciosus Lee, and (2) Hippoleptop» tribalus Fab.,
the latter from a specimen kindly sent by Mr. H. Jekel, which
although foreign (New Holland), was of sufBciently large size to allow of
the drawing being made natural size. In the cut the mcsosternal epimeron
is left entirely black that its position as well as the form of the adjacent
parts, might be rendered more evident.

An examination of the foreign genera in the cabinet of the Academy of
Nat. Sc, Phila., shows that the use of the above characters may be extend-
ed to genera not represented in our fauna, and by means of them foreign
genera, evidently allied, may be brought in much closer proximitj' than by
the system adopted by Lacordaire.

No genus in our fauna presents any extraordinary or anomalous charac-
ters. It may be remarked that no native species yet known is provided
with any femoral armature, and all our genera with the exception of
Agraphus have seven joints in the funicle of the antennaj.

By reference to the synoptic tables, the extent of variation in other por-
tions of the body may be ascertained.

In consequence of the definition of the present family by the presence of
the mandibular scar, the primary characters made use of by Lacordaire sink
into even less than secondary importance, and as we have in the tenehri-
ONiD^ parallel series each with genera of maximum and minimum develop-
ment of mentum, so we have in the RJiynchopliora similar parallels in the
two divisions above indicated.

In taking the structure of the sternal side-pieces as a primary means of

dividing this family, I liave found tliat genera are tlicrcby approximated
wliicli are now widely separated, and ot which the best authoriies on the
subject since Lacordaire acknowledge the affinities. I might cite Laptops
and Entimus in their approximation to Vyphus and lihigut, the separation
of Brachy»tylua from the Otiorhynchi and its position near Cyphus as well as
Artipus from its present very unnatural position to a place near Gyphua.
The character is therefore suggested as a better method of subdivision,
although it is not claimed that it will in all cases be found infallible. A
very limited study of the Rhynchophora will soon produce a conviction
that there is on the one hand a great permanency of type of construction,
and when variation of detail does occur, it is so gradual as to leave no
abrupt lines of division.

DIVISION I.

This division contains those genei-a in which the mesosternal epimera are
small, or at most moderate, the episterna in contact with the elytral margin,
the metastemal side-pieces rarely of more than moderate width and not
dilated at anterior end, and without the triangular process projecting
between the mes-epimera and the metasternum. The other characters of
the division are extremely variable, in all, however, the antennae are strongly
geniculate. All the genera of this Division in our fauna have a large men-
tum concealing entirely the maxillfc, excepting in the last tribe.

The following tribes are represented in our fauna :
Thorax without ocular lobes.

Antennal grooves (scrobes) lateral directed

inferiorly BBACHYDERINI.

Antennal grooves short, superior, rarely late-
ral, and then directed toward the eyes UTiOKHYlVC'imvi.

Thorax with ocular lobes more or less distinct.
Mentum at least moderate, concealing in great
part or entirely the maxilla;. Mandibles ro-
bust not prominent, scar very evident OPHRYASTIXI.

Mentum very small, maxillse exposed, mandi-
bles prominent, free edge rather thin, scar

small, very narrow DiRorooNATHiKi.

As will be seen by the above table the presence or absence of ocular
lobes affords the only means of separating the tribes Brachyderini and
Ophrya»Uni, and the character must be strictly interpreted. The latter
tribe has the ocular lobes sometimes very feeble and almost wanting, but
as the lobes disappear the flmbrise become more evident. In the former
tribe there are no evidences whatever of either ocular lobes or fimbria;. In
one genus, the prosternum is more emarginate than usual, giving an
appearance of slight ocular lobes, but no traces whatever of flmbriee are
seen. In some of the genera of Ophryastini, the metastemal side pieces
become of moderate width, showing somewhat of an approximation to the

genera of the second division. Tlie side pieces in the other two tribes are
very narrow and the sutures nearly always obliterated.

Tribe I. bkachyderini.

Rostrum at least as long as the head and slightly dilated at tip, which is
more or less emarginate. Front flat, rarely with a slight deprosaion
between the eyes. Scrobes moderately deep, usually distinctly limited and
very oblique. Antennie moderate, scape attaining the eyes rarely ( Trigo-
noscuta) passing them. Thorax without ocular lobes or fimbriie and not
or very feebly emarginate beneath. Scutellum usually distinct. Elytra
oval, not wider than the thorax. Mesosternal epimeron small, episternum
attaining the elytra. Episternum of metasternum narrow suture usually
distinct in its entire length. Abdomen with the first two segments (except
in Gr. iv), separated by an arcuate suture, segments 3-4 short, conjointly
not or but little longer than the second.

As thus constituted, the tribe is widely different from that defined by
Lacordaire under the same name. From it those genera have been re-
moved in which the mesosternal side pieces are diagonally divided and the
metasternal episterna moderately wide and dilated in front. These form
tribes in the next division. It is, however, extremely difficult to fix tribal
limits with any degree of certainty, as everj' character upon which classifi-
cation has been baaed, exhibits a degree of variability almost unparalleled
in any other series of Coleoptera. The ocular lobes of the thorax especially
exhibit this tendency, and the pointed outline of the eye which usually
accompanies the lobe is by no means in better condition. The eye may be
more nearly circular in outline with a lobe than it is without the lobe.

As thus constituted, the tribe contains the following groups :

Third joint of all the tarsi wider than the second and deeply bilobed.
Tibia; normal, not dilated at tip. Scape not passing the eyes.

Posterior coxoe small, very widely separated

Posterior coxaj normal intercoxal process triangu-
lar or oval.
Antennffi scaly, body beneath densely scaly. Elytra

emarginate at base, thorax closely applied

Antennae shining, sparsely hairy, body beneath
nearly naked.

Tips of 1 ind tibioe feebly cavernous, a double row

of spinules. First abdominal suture arcuate...

Tips of hind tibse open, a single row of spinules.

First abdominal suture straight or nearly so ..

emarginate Caiyptllll.

Group I. Mlny^-^eri.

Rostrum stout, cylindrical, as long as the head, and very little narrowed
to the tip. Scrobes di'ip, well defined, suddenly arcuate in front, gradually
wider behind and jjussing beneath the eyes. Mesosternal side pieces
unequal. Metasternal episternum linear, suture distinct. Intercoxal pro
cess very broad and very short. Hind coxte very small. Corbels of hind
tibia; open, tarsal claws free.

The form of the head, rostrum and scrobes resembles considerably that of
Pandeletejus of the Second Division, but the structure of the sternal side
pieces excludes the present genus from anj^ such association. According to
the system adopted by Lacordaire, this genus would be placed in the
Brachyderides vrais.

short and feeblj' broader externally ; club elongate, oval, pointed. Thorax
cylindrical, truncate at apex and base, without trace of ocular lobes or

humeri broadly rounded. Middle coxte moderately separated. Mesostcr
nal r.ide pieces unequally divided, elytra and episterna tontiguous. Me-
tasterral episternum very narrow, linear, suture distinct. Metasternum
short. Posterior coxie small, very widely distant. Intercoxal j)ro-
cess very short. Second abdominal segment as long as the two following
united, separated from the first by a suture arcuate at miiidle. Front and
middle tibite feebly mucronate at tip, corbels of hind tibia; open. Tarsi
with coarse hairs beneath, third joint feebly bilobed. Claws free. Bo<ly
densely scaly.

The feeble transverse impression of the head behind the eyes is a charac-
ter of extremely rare occurrence, which is found also in Proictes, 8ch.
Some relationship might be expected between the two genera. I have not
been able to inspect many of the genera belonging to the group Brachyde
I'idea vrais, but from those seen, I am inclined to think that nearly all
should be referred to the Second Division of this memoir.

Two species are known to me :

arcuate innocuus.

Thorax as long as wide, slightly narrower behind languidus.

In both species the deciduous piece has left a very inconspicuous scar,
transversely oval in form and not prominent as in several of the following
groups. I have not seen specimens with the pieces remaining. The men-
turn fills completely the gular emargination which is nearly semicircular in
form. The genae are notched opposite the bases of the mandibles. The
distance between the posterior coxae is equal to the length of tJie first two
abdominal segments, and the coxa; are not larger than those of the middle
pair.

Group II. Eplcnerl.

The species composing this group are more or less pyriform, the body
above and beneath densely scaly, the elytra of a pale-brownish or luteous
color with the tip and two sinuous bands much paler. The rostrum is
rather stout, usually longer than the head, the scrobes deep, well defined,

• The measurements here given as well as all to follow in the present paper,
are taken from the apical thoracic margin to the tip of the elytra, as this U

dibles are moderately or very prominent.

The genera known to occur in our fauna may be recognised by tlie
following table :

of deciduous piece moderately prominent.
Antenna; stout, last joint of funicle short
broad, and very close to the club. Joints

tennifi rather slender, club distinct ANOMADUS.

the upper inner side concave, smooth and shining.

QRAPHORHINUS Sch.

Oraphorhinus Schonhcrr, Gen. Cure, i, p. 510 ; indicated but not de
scribed by Say.

This genus has all the essential characters of Epiccerus, and diflFers only
in the following particulars :

Antennre shorter, scape slightly clavate, attaining the eyes, funicle
7-jointed, first two joints slightly larger than the others, 3-6 as broad as
long, the seventh broader than long, and In close proximity to the club,
the latter broadly oval and pointed at tip. Eyes nearly round, slightly
transverse. Cotyloid cavities of hind tibia; terminal (coriejKes ouvertei<)
and glabrous, tarsi beneath glabrous slightly fimbriate near the tips.

Bj' the above characters it will be seen that the genus difiers from
Epiemrus in the form of the antenna;, the form of the i>osterior cotyloid
cavities and the vestiture of the tarsi. The species below being the type of
the genus, and as it differs in several particulars from the Oraphorhinun as
described by Lacordaire from other species, these should constitute another
genus differing in the fonn of the antennae and the vestiture of the tarsi.

allied to Ci/p/ius as will be seen further on.

Group IV iiormorl.

Rostrum longer and narrower than the head, subcylindrical at base,
broader at tip, alse moderately divergent, apex emarginate and with a V
shaped elevated line, median line distmctly impres.sed. Scrobes deep in
front, and moderately arcuate, posteriorly fecl>ly marked and directed be-
neath {Ilormoru^) or toward the lower border of the eye (Agasphcerops).
AntenniB moderately long, attaining the middle of the eye in the former
and barely reaching the eye in the latter. Eyes moderately or very promi
nent. Metasternal side pieces almost entirely concealed by the elytra ;
metasternum short. Intercoxal process broad, truncate, second abdominal
segment but little longer than the third and separated from the first by a
straight suture. Corbels of hind tibiae open, claws of tarsi free.

The supports of the deciduous pieces of the mandibles are very promi-
nent, obliquely truncate and pointed at tip ; the deciduous pieces do not
exist on any of the specimens before me. The open posterior corbels and
the straight first abdominal suture would seem to placj the two genera here
included in Lacordaire's Dlosyrides with which, however, they have but
little in common.

Two genera are thus separated :
Scape attixining the middle of the eyes, the latter

moderately prominent, without posterior orbit. HORMOBUS-

Scape barely attaining the anterior nargin of the
eye, the latter spherical, prominent and with
posterior orbit AGASPH^ROPS.

These two genera have the elytra at base feebly emarginate :md some-
what broader than the thorax, the humeri being bn)adly rounded in tlie
latter and subrectangular in the former genus. There is also a close super-
ficial resemblance to Otio.hyni'.huH, especially in the second, where the sur-
face is black and with few and inconspicuous scales. IIormoruK is how-
ever more ornate as will be seen in the dcscriptio'i. I have endeavored to
find cenera to which these are allied, but with the work of Lacordaire and
the lin)ii''d foreign •olleclion at my disposal I am entirely unable to do so,
I must then-fore describe them so far as to make tliem recognizable in our
faima aud leave their relationships for future determination.

cription given bv Motsclmlsky is so extremely vague and short as to be
entirely valueless, and in strict justice the genus should be credited to
Lacordaire.

T. pilosa Motsch. Etudes Entom. I, 1852, p. 79 ; Lacord. Genera,
Atlas pi. 61, fig. 5, a-b.

Form oval, robust, surface densely covered with cinereous scales and
moderately long greyisli liairs s^jarsely placed, elytra irregularly varie-
gated with fuscous. Head and rostrum as long the tliorax, densely scaly
and sparsely pilose. Antennte rufous, hairy. Thorax broader than long,
narrower in front, sides strongly arcuate, disc convex, surface moderately
densely scaly. Elytra rather broadly oval, humeri broadly rounded, sides
feebly arcuate and slightly acuminate posteriorly, disc convex, with rows
of miidcrately fine punctures, surfiice dense'.y scaly and sparsely pilose.
Body beneath moderately densely scaly and with rather longer hairs than the
upper surface, last three segments of abdomen distinctly pubescent. Legs
" ore sparsely scaly and with rather long greyish haira. Length .23 — .36
. :';h; 5.5 — ^9 mm.

Tlio males l;;ive the metivsternum and abdomen broadly concave. The
scales covering the elytra and, in fact, the entire upper surface are very
variable in coloration. The ground color is a cinereous usually very irregu-
larly mottled with fuscous. Occasionally specimens occur in which the
elytra arc pale ochreous with an irregular band on the middle of each ely
tron becoming gradually broader behind, nearly uniting at the suture.

This species is not rare on the sea-coast at San Francisco, Cal.

Group V l. CalypttlU.

Rostrum not longer than the head, sub-quadrangular, very slightly nar-
row ad toward the tip and but lit('3 narrower than the head. Eyes lound,
coarsely granulated and almost entirely concealed from above by a small
tubercle. Scrobes lateral, arcuate, deep. Thorax without ocular lobes or
flmbrite. Scutellum very indistinct. Mesosternal side pieces very un-
equal. Metasternum short, side pieces moderate, suture obliterated. Ab-
domen normal, intercoxal process broad truncate in front. Tarsi with
coarse spinous hairs beneath, third joint not wider than the second and
feebly emarginate, last joint moderately long, claws free. Anterior tibiaj
feebly mucronate and digitate at tip with four or five coarse spinules, articu-
lar ca' 'ties of hind tibiie cavernous.

The gular emargination is moderately large and without sub -mental
peduncle. The mentum is nearly semicircular in shape and partially ex-
poses the other oral organs, the maxilla) being slightly visible at the sides
and the ligula at tip.

The combination of characters above given will be found very difficult
to place in any tribe of Lacordaire's system. The genus can not be called
Phanerognath, as the mentum conceals the greater portion of the oral or-
gans, and I am equally at a loss for a iwsition in the Adelognath scries.

The occurrence of narrow tarsi in this portion of the series is certainly

a remarkable circumstance and serves to illustrate the almost utter impossi
bility of dividing any portion of the Iliiynchophorus sub-order without
apparently doing violence to some imi)ortant character. As the present is
the first occurrence of this character, it might be here observed that two
others alwaj'S accompany it (in our fauna) viz. ; — The appro.ximation of the
last joint of the funicle to the club and the tarsi more or less spinous be-
neath. Ophri/astes, Ithigopsis, and Cimboccra, the only genera of Otio-
rhynchidse in our fauna with narrowed tarsi, all have the other two char-
acters. The tarsi may, however, be more or less spinous in other genera,
but the antennal character never occurs Avithout narrowed tarsi.

eludes very heterogeneous material as must be evident to even a superficial
observer. No one can deny the necessity of approacliing Entimux and its
allies to Gyphm, forming a distinct tribe, liowevcr, from the latter, and at
the same time Zdp<07)« must be similarly dealt with, and should probably
be placed with the Entimides. As far as I have studied the majority of
the genera of the group Leptopsides vrais, should remain in the present
tribe.

As Leptops belongs to my second division, I have been compelled to
change the name of the tribe, and have adopted that of our most prominent
genus.

As interpreted in the present paper, this tribe has the following charac-
teristics :

Rostrum moderately or very robust, quadrangular or sub-cylindrical.
Mandibles robust, never prominent or laminiform at tip, scar round, very
distinct and sometimes prominent. Mentum large or at least moderate,
concealing in great part the otlier oral organs, sub-mentum rarely feebly
pedunculate. Scrobes lateral, rarely (Phi/xelis) visil)lc fronx above, di-
rected either toward the middle of the eyes or inferiorly. Antennie mode-
rate, scape always attaining at least the eye, funicle 7-jointed, the last
usually free, rarely (Cimbocera and Ophryanteit) contiguous to the mass.
Thorax always with distinct ocular lobes which are frequently flml)riate.
"M-ptasternum usually very short, side pieces usually narrow, suture nearly
ahvays visible. Mesosternal side pieces unequally divided, episternum
and elytral margin contiguous. Intercoxal process at least moderately,
sometimes very broad (RhigopsiK). Abdomen variable, second segment
longer than the two following united (except in Ophryastes), and with the
first suture arcuate (except in Ophryaates and some Strangaliodea). Tarsi
variable, usually pubescent beneath, sometimes spinous ; third joint usually
deeply bilobed and broader, nirely simply emarginate and not wider than
the second, (certain Ophrymtea, and in Gimbocera and Ehigopsin). Claws
always free. Body always ajjterous.

The tribe contains moderately hon\ogeneous material but with evident
tendencies in some of the genera to closely approximate those of neighbor-
ing tribes, especiallj' is this the c^se in those genera with the feebler ocular
lobes. Tiius Phyxelis approaches Trachyphloeua and Phymatinns to
Otiorhynehwt. There is very little tendency to approch Division II,
Phymatinus alone having the mcsostern.il side pieces nearly equally divided
but the metasternal parapleurie are not at all like those of that division.

The genera of the tribe form the following groups:

Rostrum robust, quadrangular, more or less distinctly trisulcate above.

Scrobes rapidly inferior, well defined. Eyes always narrow and acute

below, partially concealed by the ocular lobes.
Abdomen M'ith second segment rarely as long

as the two following together, first suture

straight. Intercoxal process moderately

wide Ophrya«t«a.

The groups as above defined are very distinctly limited in our fauna, the
last group alone being of doubtful value.

In this tribe, occur genera with the narrow third tarsal joint, which
however, is not of the form seen in the BynsopiD^. This character will be
spoken of at greater length in the genera In which it occurs.

Group I. Ophryastcs.

Rostrum robust, angular, more or less distinctly trisulcate, tip feebly
cmarginate with a small triangular smooth space. Antenna; moderately
robust, scaly, scape gradually thicker, nearly attaining the eyes, funicle
7-jointed, the last joint contiguous to the club which is oval. Scrobes deep,
passing obliquely downwards in "'ont of the eyes. Eyes oval, transverse,
pointed beneath. Thorax variable in form, either oval or transverse, :nid
with callosities at the sides. Elytra oval or oblong. Scutellum wnncing.
Abdominal sutures straight, second segment equal to, or very little longer
than, the third. Tibiae not mucronate at tip. Tarsi variable. Claws free.
The articular surfaces at the tips of the hind tibiae are verj' nearly termi-
nal and in great part scaly. Lacordaire calls them " cnrerneuse," hnt I
think without reason (for the majority of the species). They arc cavernous
in some Eupagoderea. The mesosternal side pieces are very unequal, the
epimeron being very small. The metathoracic episternum is moderately
broad and the suture more or less distinct. In all the species the ophthal-
mic lobes are of moderate size and fimbriate. The surface of the body is
densely scaly and without anj'^ pubescence.
Two genera appear to be indicated in our fauna.
Tarsi slender, third joint not wider than second,
and simply enuirginate. Sides of thorax with
tuberosities more or less marked. Tips of tarsal

joints beneath spiniform OPHRYASTES.

Tarsi dilated, third joint usually wider than
second and deeply bilobed. Thorax oval
without tuberosities, tarsi beneath not spinous

at tip EUPAQODERES.

In the first genus the elytra are broadly oval, in the second elongate
oval. In the latter also, the legs are longer.

The species of this genus as restricted by the preceding table, are not
numeroVis, and have a facies at once distinguisliing tlieni from the follow-
ing genus. They are all of robust form, elytra rather broadly oval and
the surface densely scaly, either cinereous or whitish, ornamented with
8trij)cs or spots of a much darker color. Considerable variation within
specific limits is found, not only in color but also in form. All the species
with but one exception, have at the base of the rostrum a distinctly marked
transverse impression and the vertex thus appears convex. Tlie tenth
elytral stria in the larger species is very distinct at its basal third, and as
distant from the ninth as the latter is from the eighth, at middle the stria
is not evident, and at its apiciU third very close to the ninth. In the smaller
species, in which also the thoracic tuberosities are very feeble, the tenth
stria is entirely obliterated. The deciduous mandibular piece is moderately
long, acute at tip, slightly arcuate. This piece when cast leaves merely a
a scar without any process.

In accordance with the characters our species may be tabulated in the
following manner:
Tenth elytral stria distinct at basal third. Thoracic

tuberosities large 1

Tenth elytral stria almost entirely obliterated.

Thoracic tuberosities feeble 2

l-Rostru'n without transverse impression. Median

groove attaining the occiput vittatus.

EUPAGODERES, n. g.

This genus contains those species, formerly placed in Ophryastes, with-
out lateral thoracic tuberosities. The tarsi are more dilated, the joints
proportionately shorter and the third more distinctly bilobed. The distal
angles are not produced in a spiniform process, a character by no means
constant, however, in Ophyrastes. In this genus the articular cavities of
the hind tibia; become internal and the tip of the tibia truncate, showing
an oval scaly space. The transition from the double apical fringe, which
is usual, to the truncate tip with the two rows of fimbria' surrounding an
oval space is in this genus so gradual, even Avith the limited number of
species, that it seems to indicate the little value of the characters drawn by
Lacordaire from " corbeillen ourertes" and " corbeilles cuverneuses." The
deciduous mandibular i)iece is similar to that of Ophryastes. As in the
latter genus some species have the rostrum and vertex continuous, the
greater number, however, have a siuuation at the base of the rostrum. 0.

Group IIT. Strangallodea.

The group as made up in the following table is not precisely that in-
tended by Lacordaire. There are without doubt several genem which
should be placed in his Kreiniiides, but with the exception of Phi/xelis I
can find no genus presenting such marked diflerenees in the form of the
scrobes as to render it possible to draw the line with any degree of accuracy
between those generc in which the scrobes are strictly lateral and those
with the scrobes arcuate and directed inferiorly.

The arrangement of the genera in the folluwipg table exhibits a gradual
transition in the form and length of the rostrum from Diehorenus which
approaches most nearly Ophryanten in this resnect as well as in the struc-
ture of the scrobes and abdomen, to Phym<i,tiini» with a long rostrum
almost entirely lateml sciobes and normal al)domen. Cimhoceni by its
narrower tarsi and the structure of the antenna* appv -.ches Oj)hryn*te» in
another direction. Melamomphm resembles almost pn-cisely Amomphim
in form.

I have not been able to obtain any characters from the form of the corl)el8
of the hind tibim, but have been compelled to group seven genera l)y a
character almost as feeble, the presence or absence of mucro at the tip of
the hind tibia. Our genera exhibit such a similarity of strufture that it
is almost Imjiossiblo to define their limits and with the addition of new
material generic definition will be reduced to a work of extreme difticully.

This genus should probably be referred to the group Lejitopsidcs of Lacor-
daire by its rather (piadrangular rostrum although the lateral grooves and
carma are here entirely wanting. Whether the genus be placed in the

terize it as distinct from any genus there described.

Rostrum longer than the head and slightly narrower, slightly wider at
base and apex than at middle, alic very feebly divergent, base cylindrical,
apex sub-quadrangular and feebly emarginate. Front convex separated
from the rostrum by a feeble transverse impression. Scrobes deep in front,
rapidly evanescent posteriori^', slightly arcuate and directed toward the
middle of the eye. Eyes transverse oval, obtuse beneath. Antennre
moderate, scape feebly thicker to tip, attaining the hinder margin of the
eye ; funicle 7-jointed, first joint nlightly longer, 2-7 obconical and gradu-
ally shorter ; club elongate oval, pointed. Thorax oval, not wider than
long, lobes broad but very short, fimbriate. Scutellum confined entirely to
the peduncle. Elytra oblong oval, not wider than the thorax. Jletasternum
short, side pieces moderate, suture distinct. Intercoxal process quadran
gular, arcuate at apex. Second segment shorter . an the other two united,
first suture very nearly straight. Anterior tibia; mucronate, arcuate in
both sexes, denticulate within, middle tibiaj straight, mucronate, hind
tibise straight $ or suddenly arcuate near the tip and furnished with a
brush of moderately long silken hairs (f, not mucronate at tip. Articular
cavities of hind tibiaj open. Tarsi aormal. Body densely sciily and with
very short haire.

Having found it necessary to separate the species of Dydobm to form
two genera, I have chosen as the type the first species mentioned (D. Her/niit)
especially as it is the only one in which the second abdominal segment is
rather short, and the first suture straight. This genus must be j)laced near
Panscopus, which it resembles somewhat in form but is rather more elon-
gate.

tibia; distinctly cavernous. Claws moderate, free.

It is not without doubt tliat I consider the genus before me identical with
Mimeten. The thorax is provided, in well preserved specimens with the
post-ocular thoracic finibriic characteristic of the Tanyviecide% of Lat-or-
daire. Tiiese hairs are however very easily removable, and it is possible tliat
Lacordaire may have had a sjiecimen before him similar to one now at hand.
The present species has been submitted to Mr. H. Jekel, who agrees with
me in placing it near Amoinphua and its allies. The mandibles have no
prominent support for the deciduous piece. In addition to the characters
given in the table, this genus has a much less robust rostrum and the fmn-
tal impression is between the eyes and not at a distance in front as in
Oi'imodema.

This genus is a part of that included by Dr. Leconte in IJffilohus, the
generic description of which appears to have been made from D. si'f/nisAnd
A. granicolU» of the i)resent genus. I have retained the name J)i/Hli>l)uit
for the species with the tirst alulominal suture straight as this (•hanict(;r is
the most im])urtant and striking in the description. Regarding the position
the genus should occupy in the groups indiciated by Lacordaire, 1 am in
some doubt. The scrobes are lateral, feebly arcuate anil directed toward
the lower front of the eye. They do not become rapidly inferior as in
several genera already noted, and are but slightly less arcuate and less (l«^
fined than in Pamcopus.

For the present, I prefer to retain Amnesia in the present group as one
of the leads toward the PhytoHcaphi to which the next genus probably
belongs, Nocheles in turn being a lead toward the Kremnini.

I consider (Dynlohns) granicollis Lee. the type of the genus.

The following table will make our species easily known :

Hairs of the surface, especially on the elytra, very short and incon-
spicuous. Humeri rectangular, ii:itcrior tibise
moderately denticulate.
Body beneath rather sparsely and not coarsely

punctured granicoUis.

Body beneath with coarse deep punctures,
denser on the Intercoxal process ami last ven-
tral segment decorata.

Hairs of surface very distinct, usually ratlier long.
Humeri rectangular, anterior tibiic moderately
denticulate.

Surface of thorax even, not granulate ursina.

Surface of thorax granulate, each gninule punc-
tured rauca.

Humeri obliterated, anterior tibiae feebly dentic-
ulate, surface of thorax with punctured granules.
Elytra oval, wider at middle than the thorax,
and not twice as long as wide.
Thorax not narrowed in front, granules incon-
spicuous, surface densely scaly ; elytra witli
cinereous scales alternata.

Although very different in appearance from the preceding species, ,thcre
is some difficulty in finding characters expressible in words to .separate the
two. The thorax of the present species is relativ 'ly mudi broader and at
its widest part but little narrower than the elytra. The alternation of eleva-

This genus, as suggested by Dr. LeConte, should probably be referred

distinct transveree impression. Thorax somewhat variable in form, broader

The color of the coating varies very greatly, usually pale ochreous some-
times dark brown, and it adheres so closely and so obscures the true sculp-
ture of the insect as to render it almost im{H)ssible to obtain an accurate
idea of the surface. I cannot find any reason for distinguishing three
species in our fauna.

OTIOKHYNCHID^.

Tribe II. OTIORHYKOHI.%1.

[Horn.

Antonnaj Ions, scape always passinj; the eyes behind. Scrobes variable
but never at the same time linear and directed interiorly. MetaHternal side
pieces usually entirely concealed by the elytra, rarely of moderate width.
Mesosternal epimora small. Elytral striie entire in all our j^enera, tenth or
marginal always distant from the preceding in its entire length.

It is extremely difficult to give characters which define tril)es of Uhyn-
cliophoni with any degree of certainty, and it is frequently found that a
species can only be assigned a position by the consideration of almost its
entire structure with considerable allowance for facies, and not a little, by
the experience of the student.

Some of the genera placed in the Otiorhj/nchini by Lacordaire, have been
removed and will constitute portions of tribes in Division ii, with wide
metasternal side pieces.

Our genera form four groups which may be distinguished as follows :
Funide C-jointed ; articular surface of hind tibioj
enclosed, tips of hind tibiic truncate with

broad oval space

Funlcle Tjointed ; articular sdrface free, tips of
hind tibia' with a single row of fimbrite.
Claws free.

Antenna' long ; outer joints of funicle long.
Antenna; shorter; outer joints short or moni-

liform i

Claws connate.

An'ienntu as in Otiorhynchi

The Pen'teliaTii i)laced after the Otiorhynchi from their greater similarity
of form and structure, the only difference between the two tribes is found
in the claws.

Group I. Avrniihi.

Antenna' moderate, scape longer than the funicle and club, moderately
arcuate ; funicle (i-jointed ; club broadly oval slightly flattened, composed
in great part of the first joint only, the other joints retracted and very, in
distinct. Tarsi long, slender, third joint very feebly emarginate and
scarcely wider than the second. Hind tibiie truncate at tip with broad,
oval smooth space, cotyloid cavities internal. Anterior tibite with outer
apica' angle slightly prolonged ; anterior and middle tibia' with innerangle
mucronate.

The a\)o\ e characters appear to warrant the separation of Agraphits as a
group b}' itself as suggested by Lacordaire who, however, failed to notice
the structure of the antennal club and placed the genus in a groui) in
whicL the hinder cotyloid cavities are open. These latter are really very
strongly cjivernous, more so in fact than in any other genus in our fauna.

Agraphus alone constitutes this g'*oup.

OtiorhyncJnii Germar, Ins. Spec. nov. p. 343.

Rostrum as long as the head, moderately robust, more or less dilated at
tip which is notched at middle. Antennic anterior long ; scajw long, very
slightly arcuate not longer than the funicle and club, attaining the thorax ;
funide 7 jointed, first two joints longer, joints !J-7 obconical. Scrobes supe-
rior deep, sides strongly divaricate behind. Eyes rounded or slightly oval.
TIjoraxoval, longer than wide. Elytra variable, broadly or elongate oval.
Bcutellum very small or indistinct. Legs modemtely long, thighs clavate,
tibia; feebly arcuate near the tip. Cotyloid cavities of hind tibia; terminal.
Tarsi moderately dilated, spongy pubescent beneath, third joint deeply
bilobed. Second abdominal segment not as long as the two following united,
8e|iarated from the first by an arcuate suture.

This genus contjiins in our fauna species which have been introduced
from Europe, and which liave established themselves in the north-eastern
parts of our territory. Two are found in Greenland, which also occur in
the extreme north of Europe, their distribution being due to natural laws
and not through the agency of commerce.

The species arc known as follows:
Femora toothed.

Tooth very small. Rostrum sulcate, at tip with a
bifid airina, elytra sulcate sulcatus.

Tooth large, rostrum not sulcate, tip not carinate,

elytra not sulcate ligneus.

Femora not toothed.

Form oblong, brown black, sub-opaque. Itostrum suleate at middle, tip
emarginate and with a V shaped carina ; surface spars«'ly and coarsely
punctured and sparsely hairy. Thon»x sti'i cylindrical, sides moderatelj*
arcuate, widest in front of middle, not longer than wide, surface with
rounded tubercles rather closely placed, each l)earing a short hair. Elytra
oblong oval, disc slightly flattened, humeri obtusely rounded, surface

a row of shining rounded tubercles rather closely placed and with small
jMitches of short yellowish hair irregularly placed. Bo<ly beneath black,
shining and very sparsely hairy. Femora strongly ( lavate, deeply sinuate
near the tip and with a very small acute tooth. Length .34 inch ; 8.5 mm.

This species has been so often described in easily accessible European
publicUions, that I consider it unnecessary to aild to the above <lescription,
this with the table being sufficient to cnaldc it to be recognized by the
student of our fauna.

Occurs in Massachusetts, Canada, Newfoundland and Nova Scotia.

O. ligneus Oliv. Ent. v, 83, p. 378, pi. 31, fig. 473.

Form oblong, color piceous, shining. Rostrum flat, emarginate at tip.
surface very coarsely and closely jiunctured, between the lyea a deep
puncture. Thorax nearly sidiericjil, truncate at apex and lui'^e, surface
tuberculate, (at middle the tubercles become confluent in rows with deep
sulci between them), each tubercle punctured at summit and bearing a
short hair. Elytra oval, striate at the sides, striic obsolete on the di.sc and
'.vith coarse punctures closely placed, intervals flat on the di.sc and feebly
muricate, at sides moderately convex and slightly tuberculate. Legs piceo
rufous, femora clavate, sinuate near the tip and with a modenilely strong
tooth bearing a denticle on its free edge. Length .20 inch ; 5 mm.

This is the smallest species which has occurred with us, and may be
easily known by the femoral armature and the nearly spheriad thorax with
its peculiar sculpture.

Occurs in the New England States.

This insect has been refiTred to the genus Ploehushy Si'idlitz (loc. supra

The genera above indicated are so arranged as to cxhihit a gnulual transi-
tion from till' Ptoclioid forms of the preceihng group to the Trad |)hla'oid
forms of the next. The rostrum tends to become shorter, h- . us the
advance is made from the first to the last genus. The vestiti ••• varies.
In one species Mj/I'Ichk Hdceatus Lee. the surface is sparsely ))>ibescen'
without scales, Peritelopm glohicentrh'Lcc., is scaly only withotit fracoi«f
hairs or settc ; all the remaining species are densely scaly and wim whoii
erect setre. As a general rule the metasternal side picees are exir'-'M-Iy
narrow in the earlier genera (entirely concealed i)osti'riorly in Mw^k-m)
and become more di^^tinctly wider in the later frenera. ' s»xarc. ». vever,
is so very indistinct as to make it almost impossible to usk In -^nicter
systematically.

The scrobes vary greatly in form. In several genera they are plainly
superior and rather short, converging al)()ve. In others it i« not easy U)
determine whether to call them lateral or sujierior. When the scrobes are
much more distinctly oiien when A'iewed from above than wIk'm seen from

in any of the other geni'ra of the group, and lln; head and rostrum r.dher

ajipi'ars to occupy a doubtful position. The frontal impression issulllcienlly
distinct to ally il to .SV'/'/.'n'«<, etc., but the structure of the abdomen will
not warrant such position. The scrobes are moreover in such position that
il is imiM)ssible to say whether they should be called superior or liiteral.

chyphlam and CiUhonniorerus. The eyes are small, round, coarsely granu-
lated, surrounded on all sides with a very distinct orbital groove. The
scrobes are deep, pass directly backwards to the eye, the upper bounding

both the above genera the present may be known by the form of the
aerobes.

C. setiger, n. sp.

Form oval, color brownish, surface sparsely scaly, elytra with rows of
clavatc scale-lilic hairs on the intervals. Rostrum densely punctured and
with an indistinct median line. Tliora.K oval, broader than long, sides
moderately arcuate, apex and base truncate, disc moderately convex,
densely punctured, a slight post-apical and short transverse impression
slightlj' behind the middle, suraice with sparse scale-like hairs. Elytra
slightly emarginate at base, oval, sides p.irallel for a slight extent, humeri
broadly roiuuled, surface striate, striie wi*h coarse punctures, intervals
feebly convex and with a row of scale-like, clavate hairs. Body beneath
dark brown, with few scales, coarsely but not densely punctured. Legs
brown sparsely clothed with clavate hairs. Length (total) .10 inch;
2.5 mm.

This is the smallest species known in our fiiuna, with the mandibular
sear. It may be readily known by its color, the clavate hairs, and the sur-
face almost entirely deprived of scales.

This insect appears to be rare. Occurs in Massachusetts.

TRACHYPHLCEUS Germ.

Trachi/pfihrint Qorm. Ins. Spec. Nov., p. 408.

Rostrum as long as the head, stout, sulxpiadrangular, slightly arcuate
and with deep transverse impression at base, feebly emarginate in front and
with a triangular elevated lino in front of which is a smooth space. Scrobes
lateral, deej), moderately arcuate and passing directly backward to the eye.
AntenuiU sub-median, moderate, scape attaining the margin of the thorax,
moderately clavatc, funicle 7-jointed, first joint longest and robust, second
slender, joints ■i-'i short, as broad as long, becoming gradually broader out-
wardly ; club oval. Eyes small, round, lateral, coarsely granulated and
with a distinct orbital groove. Thorax transversel}' oval. Elytra oval.
Scutelluui not visil)le. Metathoracic side pieces moderate, suture distinct
in its entire length. Metasternum short. Intereoxal process of abdomen
broad, truncate; seccmd abdominal segment not as long as the two following
united, seiiarated from the tirst l)y a nearly straight suture. Middle and
hind tibia' not mucronatc, anterior tit)iie mucronate and with four or live
tooth-like siiincs around the apical margin. Claws free.

This genus dill'ers by very marked characters from those wlii'-h precede.

In the latter the side pieces of the metasternum are entirely concealed by
the elytra. In this the eyes are surrounded by a distinct orbital groove
and are small, scarcelj' jtrominent and coarsely granulated. The rather
deep transverse impression at the base of the rostrum, together with the
convexity of the rostrum below this (owing to its being slightly arcuate)
give this insect a very peculiar fucies.

Tribe IV. ])iKOTOU?rATnil^i.

Rostrum longer than the head, slightly Uattened. Mandibles rather
prominent. Mentum \evy small, trapezoidal, not retracted, maxilhe and
ligula entirely exposed. Thorax with feeble ocular lobes. Metasternal
side pieces narrow connate with the sternum, with very slight traces of
suture.

These few characters serve to distinguish this tribe as represented in our
fauna, to which mav be added : Mandibles jirominent, laminifonu at tip,
inner edge strongly bi-dentate, outer edge arcuate, witlui groove and a scar-
like space near the base, apex truncate, scar terminal, small, very narrow
and transverse, deciduous i)ieces sliort, liroader at tip and obliiiuely trun-
cate. Mentum very small, supported liy a distinct peduncle which is rather
short. ]\Ieta°tcrnum rather short.

I am entirciy unable to place this triljc in or near any of those indicated
by Lacordaire, further than to state that it is Phdnerognath 8y nmeride and
belongs to the flrat section of the latter Phalanx.

One genus occurs in our fauna.

D. sordidus, n. sp.

Form oval, robust, surface moderately densely covered with (". irk cine-
reous scales, discolored dark-brown by exudation, and with very short
dark-brown hairs. Head and rostrum as long as the thorax, densely scaly,
and with few short hairs. Thorax oval, broader tlian long, slightly
narrower in front, sides regularly arcuate from apex to base, apex truncate,
base feebly an-uate, disc convex, densely punctured and scaly, scales im-
bricated, paler in color along the median line and sides, and with very
short d;irk-brown hairs sparsely i)laced. Elytra broadly oval, broader at
base than the thorax, very fee'uly emarginate at middle, humeri broadly
rounded, disc convex, finely striate, strite not punctured, intervals flat,
densely seal}-, each interval with two rows of very short, black, semi-erect
hairs. Body beneath and legs less densely scaly and very sparsely hairy,
tibi;e sparsely fimbriate within. Length .10-. 34 inch ; 4-0 mm.

This insetit resembles in form and size Phyxelis rigidcs. The color
varies in accordance with the exudation, some being very dark cinereous,
others very dark-brown. The males are slightly more elongate tlian the
females, and the sides of the elytra less arcuate.

Occurs very abundantly in the desert 'regions of Arizona under damp
logs, and was also cjllcoted by Mr. Crotch at Frot Mojave, California.

DIVISION II.

In this division are contained all those genera in which the mesoslernal
side pieces are diagonally divided into two nearly eipial pieces, the outer of
whicli (epimeron) cuts olf the inner (episternum) from any contact with
the elytral margin. The metasternal episternum is usually moderately
broad, the suture distinct in its entire length, rarely narrow, and in one
genus tlie suture is entirely obliterated. In every case, however, the
anterior end of the metasternal episternum is suddenly dilated, causing on
one side an emargination of the elytral margin (which is, however, evan-
escent), while on the inner side an acute triangular process of varying
length occupies a space between the mesosternal epimeron and the body of
the metasternum.

The antennal scrobes vary in form, position and extent. The mentum
is, in all of our genera, at least moderate and visible, excei)ting Eudingogus
and ColeoceniH where it is small and much retracted, allowing the parts of
the mouth to be visible. The beak at tip exhibits t,vo distinct forms. In
the one the gena; are rather deeply notched and allow the base of the man-
dible to be exposed ; in the other there is no emargination or a very feeble
one. Accompanying these latter characters we luvve the upper portion of
the beak more prolonged over the mandibles above in the former case,

while in the latter the mandibles are always greatly exposed above. A
lateral view of the l)eak will therefore show the tip to be obliquely trun-
cate in those with the emari^inatc gense, and squarely truncate in the other
case.

The scar of the deciduous mandibular cu.,p is very distinct in all the
genera e.vcepting Coleoccrm, and is usually on the face of the mandible,
although in some genera at the summit of an obtuse process.

The tribes forming this division are shown in the following table :

varial)le. Claws free. As represented in our fauna, this trilic does not
dill'er from the group indicated by Lacordaire, cxcei)t in the addition of
Pundelctejm.

Our genera are as follows :
Anterior coxic contiguous.

Thoni.v feebly lobed behind the eyes, (the
latter transversely oval, pointed beneath)

and bisinunte at liase

Thorax not lobed, base truncate, eyes round,

or longitudinally oval.

Anterior femora normal, the tibiic simple...

Anterior femora much longer and stouter

than the others, the tibifc denticulate

Anterior coxic distant.

Anterior femora larger than the others..

The articular cavities of the hind tibise vary in the genera. They are
feebly enclosed in Pachnwiis, more decidedl}' in Tanymecm, and entirely
open in the other two genera. Into this tribe Polydacris modestus of
Cuba should enter. It has very distinct vibrissuj composed of scales, and
the anterior coxrc are separated as in Pamieletejus. The tribe as thus con-
stituted is not very homogeneous, and with more genera would divide into
well defined' groups, each of the above genera constituting a type. With
our few genera this appears unnecessary.

Thorax broader at base than long, narrower in front, sides moderately

Body beneath den.sely scaly, scales larger and paler than aluive. Legs

10 mm.

Occurs in Florida, and Is not mre.

The ba.se of the elytra is not only bisinuate, but there is also a small
dentiform prominence contiguous to the thoracic hind angles. Lacordaire
mentions this character for two Cuban species, but not fur our own.

P. distans, n. sp.

Form elongate oval, den.sely covered with pale bluish white scales, with
faint cupreous lustre. Head and rostrum slightly longer than the thorax,
densely scaly. Rostrum with a fine median elevated line, ending in a
frontal puncture. Thorax broader than long, slightly narrower in front,
sides feebly arcuate, base feebly bisinuate, di.sc moderately convex, with
large, deep punctures irregularly placed, densely scfily. Scutellum oval,
truncate at base. Elj'tra oblong, sides feebly arcuate, base very feebly
bisinuate, humeri not dentiform in front, convex, densel}' scaly and witli
twelve rows of coarse and moderately deep punctures, intervals tlat, with
a single row of minute punctures, each bearing a longer scale. Body
beneath and legs densely scaly, and with minute scale-like hairs. Length
.32 inch ; 8 mm.

Notwithstanding the fact that the elytra are not prominent at the middle
of the base of each, I am unwilling to separate this species under a distinct
generic name. In the generic table of the Tanymeciden, Lacordaire assigns
strongly cavernous corbels to Pachmvus. This is not so in either of our
species, the posterior tibiie having at their tips merely the double row of
bristles very feebly separated. The form of the eyes ai)pears to be a
character of greater value in the arrangement of the genera of this group,
after the form of the tarsi, than any that is made use of by Lacordaire.
Too much importance seems to have been given to the form of the base of
the elytra, and it will be found that exceptions are met with frequently in
many genera.

The species above described was collected at Cedar Keys and Capron,
Florida, by Messrs. Schwartz and Hubbard.

Lacordaire places this genus among the Naupactides, having entirely
overlooked the ftmbrite at tlie side of the thorax behind the eyes. No
mention is made of the separation of the anterior coxa;. As has been
already mentioned Polydccris is closely related to Pandeleii.j..A , the
anterior coxic arc in it also se[)arated, and the sides of the thorax have dis-
tinct vibrissas composed, however, of scales. I think tiiose two genera
should make but one.

Two species occur in our fauna :

Tip of ro.strum entire, without smooth space hilai'is.

Tip of rostrum emarginate, with smooth space cinereus.

These two differ also in the form of the thorax. In the latter, the
thorax is dilated only at the middle, so that the cylindrical portions in front
and behind the dilatation are equal. In the former, the dilatation is pyri-
form, and the anterior narrower part much shorter than the posterior.

Ixostrum not longer tlian the head, robust, quadrangular, slightly nar-
rower in front, tip and gente deeply emarginate, above suleate. Scrobes
lateral deep, well-defined, arcuate and passing directly beneath the eyes.
Eyes round, moderately prominent, finely granulated. Antennse moderate ;
scape feebly clavate, attaining the middle of the eye ; funicle 7-jointed,
joint 2 longer than the first, !}-7 sub-equal, .slightly obconical ; club elon-
gate oval. Thorax broader than long, narrower in front, apex truncate,
base bisinnate. Scutellum small triangular. Elytra wider at base than the
thorax, humeri moderately prominent, rather more than twice as long as
wide, and at apex slightly acuminate. ]Metasternum moderately long. In-
tercoxal process broad, sub-truncate. Second abdominal segment as long
as the two following united, separated from the first by a feebly arcuate
suture. Articular surface of hind til)iie enclosed (cavernous), and ascend-
ing. Anterior and middle tibitu feel)ly mucronate. Body densely scaly.

The middle and hind tibiic have the articular surfaces ascending one-
third the length of the tibiiC, the edge being sharp and fimbriate with
bristly hairs. The surfaces are however entirely glabrous. In addition to
the dift'erences in the number of the dorsal segments of the sexes, the
females may be known by an additional character. On each side of the
last segment, is a short, rather deeply-lmi)ressed lino, panillel with the late-
ral margin and about one-fourth the width of the segment from the side,
beginning at the last ventral suture and extending nearly half the length
of the segment. The last ventral of the male is not so marked, and is
rather longer than in the female.

Two species occur in our fauna.

Thorax abruptly narrowed in front, sides behind the front
angles strongly arcuate. Anteriorly rather abruptly
truncate lautus.

Thorax gradually narrowed from base, sides feebly arcuate.
Apex very oblicpiely truncate, with the upper margin

decidedly prolonged over the occiput placidus.

The ditlerences between these two species are more appreciable in nature

than expressible by words. The punctures of the stritu are much finer in

placidus than in lautus.

the declivity composed of three short lines on intervals 2-3-4.

nar. . Elytra uniformly covered with nearly white scales

C. placidus, n. sp.

Oblong, more slender than lautus. Head somewhat narrower, median
sulcus broader at middle. Thorax scarcely wider than long, gradually
narrower from base to apex, sidiis feebly arcuate ; apex obliquely truncate
slightly prolonged over the head, base bisinuate, hind angles slightly
laminiform ; disc with broad shallow median fovea, and a feeble impression
on each side near the base, surface sparsely punctured with finer punctures
intermixed, very densely scaly especially in the median fovea. Elytra
similar in form to lautus but rather longer in proportion to their width ;
disc moderately convex, finely striate, and with rather fine punctures rather
distantly placed ; surface very densely scaly. Body beneath very densely
scaly and sparsely hairy. Legs densely scaly, tibiae pilose. Length .48-
.52 inch ; 12-13 mm.

The two specimens before me, both females, vary in color. The larger is
pale greenish-white, the other simply white. The scales are so densely
placed as to entirely conceal the surface color. In this respect they differ
notably from the preceding species. The more striking differences have
already been pointed out.

The color of the scales covering the body is earthy brown, the tip of the
elytm much paler and with a broad post-median dark brown fascia bor-
dered anteriorly witli paler. The tibiiC of both sexes are fimbriate within.
The last abdominal segment is acutely triangular in the female, rounded in
the male.

Occurs in Pennsylvania, Georgia, and Kentucky.

Group II. Artipl.

Eljtra oval or oblong, not wider at base than the tliorax, humeri oblique,
or broadly rounded. Scutellum distinct. Antennre long, scape passing the
eyes behind. Articular surfaces of hind tibiic cavernous. Rostrum rather
deeply notched behind the base of the mandibles.

The essential difterence between this group and the preceding is found
in the form of the elytra. The antennsB (especially the scape), are longer
and more slender. The rostrum varies in form and is usually short, stout,
flattened above and deeply notched at tip. In one genus howcjver the ros-
trum is decidedly Periteloid with less divergent alie. All the genera ex-
cepting Artijnut have the anterior tibia) denticulate within.

Our genera are as follows :
Rostrum short, s^out. Scrobes linear in front.

Articular surface of hind tibiie scaly ; anterior

tibiie not denticulate within ARTIPUS.

Articular surfaces of hind tibire glabrous ; ante-
rior tibioo more or less denticulate within.

This genus would probablj' belong to Lacordairc's Brachyderides and its
position near Eurijmetoinks. The resemblance of the species to Strophoso-
mus has already been noticed, and it may be remarked that Eurymetopus
has also been so compared. I lind, however, differences of sufhcicnt im-
portance in the descriptions to convince me that our species cannot be re-
ferred to any known genus.

Two species are known in our fauna :
Denticulation of anterior tibiic indistinct ; surface densely

scaly tesselatus.

Denticulation very distinct ; surface not densely covered .. . Fulleri.

The humeri of the first species are rectangular and slightly prominent
anteriorly and in the latter obliterated. The articular surfaces of the mid-
dle tibiiB ascend nearly as much as in the hind tibia; in tesselatus, and are
not at all ascendent in Fulleri.

This species presents two varieties.

var. tesselattis Say. Head and rostrum with earthy -brown scales, paler
around the eye and beneath. Thorax similar in color, with a narrow pale
line at the sides and a broader pale line on each side of a brcud median
brownish space. Elytra earthy-brown, on each side of suture obscurely
variegated with paler niottlings and a small pale humeral line, and a narrow
space at the side of the tip.

These specimens are found in Southern Illinois.

va}'. pallidum. This variety is of somewhat larger size than the prece-
ding, the scales covering the surface are pale-greenish white, and witli
barely perceptible darker spaces arranged in a manner similar to the pre-
ceding variety.

This variety occurs from Kansas to Texas.

Both varieties have the lateral striaj of the elytra more distinctly im-
pressed than those of the disc.

A specimen of tlie latter variety was submitted to Mr. Pascoe, who was
of the opinion that it might be identical with " Sitona durius Germ." *

A. FuUeri, n. sp.

Form oblong oval, surface not densely clothed with dark-brown scales.
Head and rostrum longer than the thorax, densely punctured, sparsely
scaly, nostrum with feeble ridge on each side from the tip nearly to the
eyes. Thorax cylindrical, apex and base equal and truncate, very slightly
wider than long, sides feebly arcuate, a fine median line, disc moderately
convex, densely punctured, sparsely scaly. Elj'tra regularly oval, humeri
entirely obliterated, base sub-truncate, surface indistinctly striate, and with
rows of large, moderately closely placed punctures, intervals flat, not
densely scaly, and with very minute sub-erect hairs ; scales dark-
brown, a whitish or paler stripe beginning at the humerus, passing along
the lateral margin, ending in a short oblique fascia at the middle of the
elytra. Body beneath sparsely scaly. Legs with scale-like hairs. Ante-

• Since the above was written the following note has been received from Mr.

" Liparus tesselatus Say. It Is a Xmipacttts sensu Sch., so very allied to the

and the habitat so distant I would have regardeu them as identical » * ♦ .
For that group of SVaupacti I have created the genus Aomopactus."

I am not aware that this genus suggested by Mr. Jekel has been described.
The remarks apply especially to the variety pallidus, FuUeri being more nearly
allied to ovulum Jek., from the Pampas, Mendoza.

PHACEPHOLIS n. g.

Rostrum longer than the head, slightlj' cuneiform, sub-quadrangular,
flattened above, and with a fine median groove, tip triangularly emarginate.
Scrobcs narrow, moderately deep, well defined, slightly broader behind
and passing immediately beneath the eyes. Eyes round, moderately
prominent. Antenna; sub-median, long, slender ; scape nearly attaining
the margin of the thorax, slender, rather suddenly clavate at tip ; funicle
7-jointed, longer than the scape, joints 1-2 long, the second much longer than
the first, 3-7 sub-equal, 7 obconical ; club elongate oval. Thorax narrower

tibiie mucronate at tip, rather strongly denticulate within. Iliud tibise

This genus resembles the preceding in form and ditfers in the structure
of the hind tibim and the more distinct scutellum. The mandibles are
moderately prominent, exposed at base by the emargination of the gense,
their surface scaly. The supports of the deciduous pieces are prominent,
and obliquely truncate. The deciduous pieces are long, slightly curved
and glabrous. I cannot satisfy myself that this genus should enter any of
the genera proi)osed by Lacordaire.

Three species occur in this genus which differ in the form of the thorax
as follows :

Thorax squarely truncate ; eyes not prominent elegans.

Thorax obliquely truncate ; eyes prominent ; head slightly

constricted behuid the eyes obsoura.

Thorax obli(iuely truncate and slightly prolonged over the

hsad ; eyes feebly prominent Candida.

The first species has the thorax squarely truncate, so that it is no longer
on the dorsal than on the sternal side. The eyes arc not prominent, and
the scales, although variable, of a metallic or pearly lustre. In the second
species the head is broadly constricted behind the eyes, the latter promi-
nent, and the thorax is obliciuelj' truncate, but not sub-lobed in front, the
scales of the surface are luteous without lustre, with darker spaces on the

scales pale cinereous or nearly white. The thorax is obliquely truncate
and somewhat lobed in front and slightly prolonged over the occiput.

P. elegans, n. sp.*

Oblong oval, moucrately robust, surface densely covered witli brilliant
metallic blue scales, varying to pearly and cupreous. Head and rostrum
as long as the thorax, sparsely punctured, densely scaly, with sparsely
placed, short, erect hairs, median line finely impressed. Thorax broader
than long, slightly narrower in front, sides feebly arcuate, apex and base
truncate, hind angles slightly laminiform ; disc moderately convex, mode-
rately coarsely punctured, densely covered with round scales and with
sparsely placed, very short, erect hairs. Elytra oval, slightly acuminate
posteriorly, sides feebly arcuate, sucface striate, stria with moderate but
not closely placed punctures, intervals tlat, densely scaly, and with two or
three rows of short, erect, white hairs. Body beneath rather sparsely
scaly and setose. Legs sparsely scaly, tibire sparsely' hairy. Length .20-
.28 inch ; fi-7 mm.

The thorax at base is very feebly bisinuate, but to such a small degree
that I have preferred to say truncate. The vestiture varies in color greatly
and is always paler beneath than above. Resembles considerably the figure
given by Duval of Eunomus ovulitm.

Occurs from Kansas to Texas. The specimens from the latter region are
more brilliant.

P. obscura, n. sp.

Form oval, robust, surface densely covered with .scales and short erect
hairs. Head and rostrum nearly as long as the thorax, head feebly con-
stricted behind the eyes, sparsely punctured, densely covered with brown-
ish scales, above each eye a paler space, head and rostrum beneath nearly
white. Thorax oval, slightly longer than wide at base, apex narrower and
obliquely truncate, sides moderately arcuate and gradually converging from
base to apex ; disc moderately convex, punctured, median line feeble,
densely covered with brownish scales, a broad paler line on each side of
middle, and a narrower line at the sides. Elytra regularly oval, scarcely
attenuate at ai)ex, disc convex, striate, striaa with moderate, not closely
placed imnctures, intervals feeblj'^ convex at the sides, surface densely
covered with luteous and brownish scales in irregular longitudinal stripes,
each interval with one or two rows of moderately long erect white hairs.
Body beneath and legs moderatelj' densely scaly and paler than the upper
surface. Length .22-.28 inch ; 5.5-7 mm.

This species has much more the aspect of Slrophosomus than any other

According to the system adopted by Lacordaire, this genus belongs to
the Emtylides of the Otiorhyncliides. The construction of the sternal side
pieces excludes it at once from the latter tribe. The scrobes, and in fact the
structure of the rostrum generally, are very nearly that of Peritehm, and
its appearance, shape and coloration do not differ remarkably from P.
grisetia of Europe. I prefer, however, to place the genus here as a de-
graded member of the tribe with affinities with the Otiorhynchini. In-

stances are numerous in every tribe of genera which have characters of
other tribes, of more or less distant position, in addition to tlic distinctive
cliiiracters of the tribe to wiiicli they belong. In addition to the above
geiu!ric characters the outer elytral striui have the characteristic form of
the other members of the tribe, the outer stria joins the next inner one third
fnjm the base. This ia not known in our Otiorhynchini.

A. erriseus, n. sp.

Form oblong oval, gradually narrower anteriorlj', surface densely cov-
ered with'greyiah scales, irregularly variegated on the elytra with darker
spots. Head and rostrum as long as tlie thorax ; a fine mecMum line extending
to tlic vertex, surface moderately densely scaly. Thorax cylindrical, some-
what narrower in front, sliglitly longer than wide ; apex truncate, base
feebly arcuate, sides moderately arcuate, disc convex, moderately denselj',
but not coarsely, punctured. Elytra oval, one and a half times longer than
wide, conjointly emarginate, humeri oblique, feebly prominent, sides
moderately arcuate and gradually divergent, apex feebly prolonged ; disc
moderately convex, feebly striate, striie with moilerate, not closely placed
punctures, intervals feebly convex, surface densely scaly, each interval
with a single row of minute sctie. Body beneath and legs densely scaly,
and sparsel}' setose. Anterior tibice with distant denticulations within ; at
tip (also the middle tibiie) finely mucronate. Length .20-.24inch ; 5-6 mm.

In many of the specimens the intervals slightly alternate in the degree of
their convexity.

Occurs in Texas.

Group III. Aphrastl.

Head broader behind the eyes ; scrobcs slightly visible from above, deep,
directed toward the eyes but not reaching them, gradually broader behind.
Antennte moderate. Elj'tra slightly wider at base than the thorax, humeri
obtuse. Scutellum distinct. Articular surface of hind tibiie not cavernous,
slightly scaly. Claws connate.

The structure of the tr rsal claws will serve to distinguish this group
from either of the preceding. The outer stria of the elytrajoins the next
inner at one-third from the base as in all the Cyphini and the genaj are
deeply emarginate.

One genus constitutes this group in our fauna.

Head broader behind the eyes, vertex convex. Rostrum slightly longer
and narrower than the head, moderately robust, subangulate, above flat

Eyes round, moderately convex. Scrobes short, deep, passing directly
backward but not reaching the eyes, moderately dilated behind and slightly
visible from above. Antennse moderate ; scape slightly arcuate, attaining
the thoracic margin ; funicle 7-jointed, 1-3 longer, 3-7 short, gradually de-
creasing and becoming wider ; club oval. Thorax cylindrical, slightly nar-

long oval, slightly attenuate at apex ; base RJiglitly broader than the thorax,
humeri obtuse. Intercoxal process moderately broad, rounded at tip.
Second segnjent longer than the two following iinili'd, and separated from
the first by a strongly arcuate suture. Articular surfaces of hind lihiic
open, slightly scaly. Claws connate. Anterior and middle tibiie feebly
mucronate, not denticulate witliin. Surface "caly and luspid.

The second joint of the funicle varies in the two species. It is slightly
longer than the first in tteniatiis and shorter in iinkolor. Lacordaire is in
error in stating that the second joint is twice the length ol ihc first in tanintus.

Our species are two in number.
Second joint of funicle longer than the first ; elytra with four

))rown stripes teeniatus.

Second joint of funicle shorter than the first ; elytra uni-
formly cinereous unicolor.

A. tseniatuB Gyll. Schonh. Gen. Cure, ii, p. 400 ; Say Cure. N. A. p.
9, witliout description.

Head and rostrum shorter than the thorax, densely scaly except at tip ;
scales pale brown above, cinereous at the sides and beneath, and with
sparsely placed short erect hairs. Thorax cylindrical, slightly luirrowed in
front, sides feebly arcuate, base squarely, apex oblicpiely truncate, disc
moderately convex, not dcnselj' punctured, densely scaly ; scales pale
brown ; a pale line on each side of middle, sides and beneath cinereous.
Elytra oval, feebly striate, striic with moderately coarse very regularlj'
placed punctures, intervals feebly convex, surface densely clot lied with cin-
ereous scales ; the second and fourth intervals with brownish scales, the
inner stripe longer, each interval with a row of very short whitish hairs.
Body beneath and legsdensely covered with cinereous scales ; tibitu sparsely
hirsute. Length .20-. 23 inch ; 5- 5.5 mm.

This insect is very well-known to most collectors. The species has
usually been attributed to Say, but as the description of Gyllenhal is really
the first, it appears just to so accredit it.

Occurs in the Middle and Southern States.

A. unicolor, n. sp.

Form elongate oval, densely covered with cinereous scales. Head and
rostrum as long as the thorax, moderately densely scaly. Thorax regularly
cylindrical, sides scarcely arcuate, apex obliquely, base squarely truncate,
disc sparsely punctured, surface densely scaly and with whitish erect hairs.
Elytra oblong oval, feebly striate, stria; with large rather coarse punctures
very regularly placed, intervals feebly convex, densely scaly, each with a
single row of short, white, erect hairs. Body beneath, especially the abdo-
men sparsely scaly. Legs moderately scaly, tibia; sparsely pilose. Length
.18 inch ; 4.5 mm.

This species is rather narrower than taniatus ; thorax more regularly
cylindrical, and with the erect hairs more distinctly visible. It difters es-
pecially in the structure of the funicle ; the second j,oin.t being but little
more than half the length of the first.

One specimen. Texas.

(0//i//««ft excepted), outer stria entire, not confluent with tlu; next. Arti-
cular surCaces of hind tibin; internal, at least moderately caveruous. Claws
free.

This tribe is constructed at the expense of the Cyphides as defined by
Laeordaire. It contains those genera in which the rostrum is elongate,
the tenth stria entire, and the gente not or very feebly einarginate. As thu.q
defined, it will probal)ly contain all of the last six genera of the C'yphides.
In examining a series of Cid)an species i)resented by Prof. Poey to the
American Entomological Society, I find the specimens of Exophtlutlmua
Sommeri having tlie fimbriie at the sides of the thorax as strongly marked
as in any of the genem allied to Tanyinecna. The elytra arc not, each one,
prominent at base, and tlu; thorax is feel)ly bisinuate. It should constitute
a new genus of 2'(tMy//W(;*rt/. In this trit:e will be included {Oeo7if,mu»)
alter"ian», in which, however, the elytra are not wider at base thrv, the
thorax. The structure of the thoracic parapleurse separates it froin the
genera allied to Epiecprns, etc.

The following groups may be recognized.
Submentum not pedunculate ; mentum broad.

Humeri prominent ; thorax bisinuate at base Exopbtlialnil.

Humeri very oblique or rounded. Thorax truncate

at base Omllcl.

Submentum pedunculated ; mentum narrow.

Humeri prominent. Thorax truncate at base Evotl.

The last group shows strong afllnities with the next tribe.

Group I. Exophlhnlmi.

Rostrum longer than tlie head, sub-quadrangular, slightly dilated at tip,
which is feebly cmarginate ; geuie moderately emarginate. Sub-mentum
not petlunculate, mentum broader than long, entirely concealing the
maxilhe. Antcnnte moderate, scape at most merely passing the eye.
Serobes narrow, moderately arcuate, passing beneath tlic e3'es. Thorax
distinctl}% at times feebly, bisinuate at base. Elytra wider than the thorax
at base, or at least with the humeri very distinct, neither oblique nor
obliterated. Scutellum distinct. Articular surfaces of hind tibiic very
feeb' y cavernous, glabrous. Claws free.

One genus represents this group in our fauna.

sparsely placed, condensed in small round patches on the elytra. Head
and rostrum sliglitly longer than tlie thorax, black, shining, moderately
densely punctured, and witli white scales very sparsely placed. Antennte
brownish, sparsely hairy. Tliorax oval, narrowed at apex, slightly broader
than long, sides arcuate, base slightly narrower and feebly bisinuale ; disc

scales very sparsely placed, becoming condensed in small round spots,
distantly placed on alternate intervals. Body beneath black, shining,
sparsely punctured and with very few scales. Legs black, sparsely scaly.
Length .2(5 inch ; 6.5 mm.

This species is of the size of L. hispidus Gyll. (Cuba) and of very
similar ornamentation. The thorax is, however, narrower at base, eyes
more prominent and vertex more convex.

One specimen, Florida.

Group IL omllei.

Rostrum longer than the head, narrower, quadrangular, and slightly

base. Elytra not wider than the thorax, feebly emarginate at base, humeri
eiiher very oblique or broadly rounded. Articular surfaces of hind tibias
very feebly cavernous.

The differences between this group and the preceding are feeble, and
with other genera would probably be united with it.

Two genera are at present known to me, one only native.
Second segment of abdomen not longer than the tw^o follow-
ing together, first suture nearly straight. Second joint
of funicle short OMILEUS.

Second segment longer than the two following, first suture
strongly arcuate. Second joint of funicle longer than

the first gen. nav.

The type of the second genus is Oeonemus alternans Boh. (Cuba). The
articular surfaces of the hind tibiae are not scaly in this species as stated by
Lacordaire, Genera, vi, p. 131. O. aureosquamosus Duval, (Cuba) does
not belong to the present tribe, but should form a new genus of Gyphini,
as defined in the present memoir.

OMILEUS n. g.
Rostrum longer than the head and very slightly narrower, cylindrical
at base, slightly flattened above, feebly dilated and emarginate at tip ;
geniE not emarginate. Scrobes deep, Avell defined, slightly arcuate, passing
obliquely beneath and slightly in front of the eyes. Eyes oval, slightly
longitudinal. Antennas moderate ; scape attaining the posterior margin of
the eyes, feebly thickened ; funicle 7-jointed, first joint moderate, second
scarcely longer than the third, 3-7 short, sub-equal ; club oval. Thorax
truncate at apex and base. Scutellum small, oval. Elytra oval, not wider

variegated with brown. Head and rostrum slightly longer than the thorax,
densely punctured and covered with cinereous scales, at tip nearly naked.
Thorax as broad as long, ajiex slightly narrower than the base, sides
strongly arcuate, median line moderately impressed, surface sparsely tuber-
culate, densely covered with cinereous scales, a broad median and narrow
lateral stripe fusoous. Elytra regularly oval, striate, stria; with moderately
coarse punctures, intervals feeblj' convex, and each with two rows of
scale-like hairs, surface densely covered with cinereous scales, disc with
large fuscous spot nearlj' divided by a transverse cinereous fascia inter-
rupted at middle. Body beneath densely covered with cinereous scales.
Legs densely scaly, femora darker at base. Length .30-.33 inch; T.^-Smm.

The facies of this species is almost exactly that of certain elongate forms

Rostrum horizontal, longer than twice the head, narrower, sub-quad-
rangular and compressed at base, tip dilated and nearly twice as broad as

Sub-nientum distinctly pedunculate. Mentum oval, longer than wide,
maxillaj slightly visible at the aides. Sorobes visible from above in front
and moderately deep, very nearly straight, very shallow posteriorly, and

sub-acute beneath. Antenna long, rather slender ; scape graduaUy clavate
and attaining the middle of the eye ; funicle 7-jointed, slightly longer than

obconicjil, the seventh longer than the preceding ; club elongate, oval.
Thorax transversely oval, apex truncate, base slightly arcuate. Scutelluni
oval. Elytra oval, broader at base than the thorax, humeri obtuse, mode-
rately prominent. Metasternum motlerate, side pieces wide, formed as
defined for tlie division. Intercoxal process broad, oval at tip. Second

mucronate at tip. Articular surfaces of hind tibiie feebly cavernous and
glabrous. Tarsi rather slender, third joint deeply bilobed, last joint slender
and as long as the first two. Claws moderate, free.

This genus lias been defined at greater length than has been the custom
in this paper, on account of the very remarkable assemblage of characters
it pi.3sents. Were it not for the very plain scar on the mandibles it might
be suspected to have some affinity with the genera allied to Alophua, etc.

oval, slightly broader than long, narrower in front, apex truncate, base
feebly arcuate, sides rather strongly arcuate in front ; median line indis-
tinct, disc moderately convex, densely punctured, scales sparse, except -.n
the median line and sides, Scutellum densely scaly and paler. Elytra

truncate or very feebly emarginate at tip. Gente not emarginate. Sorobes
short, sub-terminal. Meso- and metasternal side pieces broad, the former
diagonally divided. Articularsurfacesof the hind tibia; terminal, glabrous.
Claws connate. Tenth elytral stria free in its entire extent. Scutellum
distinct.

The above characters serve to isolate a number of genera evidently
closely allied among themselves, and also with well marked affinity with
certain members of the tribe Gyphini. The mandibular scar is not promi-
nent in any of our genera, but is round and directly on the face of the
mandible itself. The deciduous piece is modemtely long, glabrous and
regularly falciform. The mentum vaiies in size in the genera of this
group, but not to the extent of causing Scythropua and Phyllohius to be
widely separated.

The following genera compose this tribe in our fauna :

Elytra wider at base than the thorax.

Mentum entirely concealing the maxillae PHYLLOBIUS.

Mentum smaller, maxillae visible at the sides.
Rostrum slightly narrower than the head ;

alaj slightly divergent CYPHOMIMUS.

nostrum short, stout ; ahe not divergent SOYTHROPUS.

Elytra elongate, oval, as narrow at base as the
thorax.

Mentum small, maxilla; entirely exposed MITOSTYLTJS.

In Mitontylus the sub-mentum is very slightly pedunculate. Seythropus
has the gula semicircularly emarginate, and the maxillae visible at the sides
of the mentum, the other three genera have the gular notch nearly square.
lu the genera 2 and 4 the mentum is very narrow and the other parts of
the mouth very distinctly visible.

short, robust, glabrous, the scar oval, terminal and not prominent. The
deciduous pieces are long, moderately stout and falciform.

Two species occur in our fauna. In one, elegam, the anterior and midf^'e

This insect has been mentioned by Dr. Lecoate (Amer. Nat. 1874, p.
457) as being probably a Macrosti/lua.
Occurs in Texas.

Tribe V. PRO.llE€OPl?II.

Rostrum short, stout, dilated, (Coleocerus) or not (Eudiaffogus) in front,
tip emarginate. Antenna; moderate, scape passing the eyes or not, funicle
7-jointed; club oval. Scrobes deep, arcuate, confluent or not beneath.
Thorax with large lateral lobes and deeply emarginatc beneath. Sculellum
distinct. Abdomen normal. Tibia; feebly mucronate. Tarsal claws
free.

This tribe, corresponding with that of Lacordaire, may be considered
the most sharply defined and natural of the division. Its small and re-
tracted mciitum, large thoracic lobes and the deep emargination of the
front of the thorax beneath, at once distinguish it. As in the preceding
tribe the genie are entire and the muulibles covered at base.

The following arc the genera in our fauna:

Rostrum strongly dilated at tip, scrobes meeting

beneath the eyes ; mesosternum protuberant... COLEOCERUS.
Rostrum very feebly dilated, cylindrical flattened,
scrobes not meeting beneath the eyes but turn -
ing forward. Mesosternum not protuberant.
Elytra broadly oval, scutellum small. Metastcr-

num short

Elytra oblong, broader at base than the thorax,
scutellum transverse. Metasternum mode-
rately long

In the last two genera the articular cavities of the hind tibitc are shallow,
the outer free edge is, however, double in Eudiagogus. In Coleocerus the
hind tibia; is truncate at tip. forming an oval, scaly space, the outer edge
of which is formed by a moderately sharp ridge not margii ed with
spinules. The tibiae are feebly mucronate in all of the genera, although the
contrary is stated by Lacordaire.

COLEOCERUS Sch.

Coleocerus Schonh. Gen. Cure, v, p. 937.

Bathyrh Lee. Amer. Nat. 1874, p. 4(51.

Rostrum not longer nor narrower than the head, very short and stout,
alue prominent laterally and beneath, tip emarginate, in front of each eye a
triangular impression, above a longitudinal groove. Scrobes sharply de-
fined, arcuate and confluent beneath. Eyes oval, pointed beneath, not pro-
minent. Antennae moderate; scape gradually clavate, attaining the front
of the eyes; funicle 7-jointed, 1-3 longer, the first longer than the second,
3-7 short, gradually decreasing; club oval. Thorax variable, trapezoidal
(dispar) or transverse {mavmoratus), ocular lobe broad and prominent.
Scutellum transvei-se, enclosed by the elytra. Elytra oblong oval, parallel,

sliglitly wider than the thorax {marmoratus) or not. Mesostcrninn protuber-
ant in tlie form of an obtuse spine. Metasternnm moderate, side pieces wide.
Intercoxal process broad, oval at tip, second segment longer tlian the two fol-
lowing united, first suture strongly arcuate. Anterior and middle tibitc mu-
cronate, articular surface of hind tibia; internal, cavernous, the tip truncate,
and with oval scaly space. Claws free. Body oval, densely scaly.

The scar left after the disappearance of the deciduous i)ieee is small and
difficult at first to discover, and the genus was placed in the following sub-
family. (Amer. Nat. 1874, p. 461), Two other genera are very closely
allied to this, and should probably not be separated, rororhipichuH and
Periorges. The former has the thorax margined near the base as in
C'oleocerus, but the mesosternum is not protuberant; the latter has the pro-
tuberant mesosternum, but not the thoracic margin. One of our species
(mcD'inoratus) might be referred to Periorge», 1 ut the mesostermun is pro-
tuberant exactly as in Coleocerun, while in tha'. genus the protuberance is
slight and somewhat laminiform.

Two species occur in our fauna.

Thorax margined at the sides, at base dispar.

Thorax not margined marmoratus.

O. dispar Lee. (Bathyns) Amer. Nat. 1874, p. 462.

Form oblong oval, densely scaly. Head and rostrum as long as the
thorax. Rostrum deeply sulcatc, moderately densely punctured, and
densely covered with rounded scales, of dark cinereous color, a paler
line on the vertex. Thorax rhomboidal, gradually narrower from base
to apex, sides dilated near the hind angles, and with a short sub-acute
ridge, disc moderately convex, densely covered with dark cinereous
scales, median line and sides paler, a small spot on each side of middle
darker. Scutebum white. Elytra oblong, not wider than the exjianded
thorax, striate, stria) with moderately large punctures, intervals flat,
each with a row of short, erect hairs; surface densely covered with
brownish scales; tip, and a short oblique band in front of middle cinere-
ous. Body beneath and legs densely covered with nearly whi'.e scales,
darker on the outer side of the legs. Length .18 inch; 4.5 nun.

One specimen. Arizona, Dr. Webb. From memory alone, I am in-
clined to think this species identical with C. variegalus which I saw in the
cabinet of M. Aug. Salle, of Paris.

O. marmoratus, n. sp

Form of dispar, densely scaly. Thorax broader than long, sides mode-
rately arcuate, widest at middle, disc moderately convex, covered densely
with whitish scales, with black and fuscous sparsely intermixed, and a
transverse basal band black. Scutellum w'lite. Elytra oblong oval, indis-
tinctly striate, and with moderately large punctures distantly placed, inter-
vals flat without erect hairs, surface densely scaly; scales cinereous and
brown intermixed, and with three very irregular black fasciic; the first ob-
lique, the second median, transverse, the third sub-apical. Body beneath

TiiiH species is relatively more robust than the preceding. It api>ears to
constitute a form intermediate between tlie genus Periorges and Coleocerus.
It is certainly not the female of dispar as suspected by Dr. LeConte.

Occurs in Texas.

ARACANTHUS Sch.

Araeanthxis Sclionh. Gen. Cure, v, 1, p. 821.

Rostrum scarcely longer than the head, stout, parallel, finely canaliculate
above, tip feebly emarginate. Scrobes linear mo<lerately arcuate, passing
immediately in front of the eyes beneath the head, and turning slightly for-
ward. Eyes transversely oval, pointed beneath. Submentum with a short
broad peduncle, not emarginate. Antennaj moderate, scape gradually cla-
vate, attaining the middle of the ej'e; funicle 7-jointed, 1-2 longer, the first
longer than the second, 3-7 gradually shorter, slightly flattened; club oval.
Thorax slightly wider tlian long, ocular lobes prominent. Scutellum very
small, triangular. Elytra oval, very little broader than the thorax at base,
humeri rectangular. Mesosternum oblique, metasternum short. Intercoxal
process oval at tip. Abdomen normal. Anterior and middle tibiaj feebly
mucronate, articular surfaces of hind tibiiB terminal, not cavernous. Claws
free.

This genus is closely allied to Eudiagogun, and differs in having the
thorax nearly as wide at base as the elytra; the scutellum very small, and
the peduncle of the submentum not emarginate. The genus was named, but
not characterized by Say.

A. pallidus Say, Cure. p. 9; Compl. works, 1, p. 268; Schonh. loc. cit.

Form oval, surface densely scaly. Head and rostrum not longer than the
thorax, canaliculate, moderately, densely, punctured, and moderately cov-
ered with scales of a cupreous lustre. Thorax slightly Avider than long,
base arcuate, sides in front arcuate, posteriorly sub-sinuate, disc convex,
•with coarh,e, rather closely placed punctures, surface densely scaly, scales
fuscous, sides and median line paler. Elytra oval, scarcely striate and
with rows of moderately large punctures not closely placed, surface densely
covered with cinereous scales, finely variegated with fuscous, and with
short, erect, whitish hairs. Body beneath and legs very sparsely scaly.
Length .12 inch; 3 mm.

Many of the scales covering the surface have a slight cupreous lustre, es-
pecially those near the sides.

Occurs in Texas and Missouri.

gradually clavatc, slig' *'y arcuate, passing slightly the anterior border of
the eye; funicle 7 jointed, 1-3 feebly elongated, the first longer than the
second, 3-7 gradually smaller; club oval. Thorax broader than long, base

cess broad, oval at tip. Second abdominal segment longer than the two fol-
lowing, first suture strongly arcuate. Anterior and middle tibiie mucronate
at tip, articular surface of hind tibiaj internal, not cavernous. Claws free.
Botly densely scaly.

This genus may be at once distinguished from all the others of the tribe
by the acute emargination of the submentum.

Two species occur in our fauna, which are distinguished as follows :
Scutellum transverse, twice as wide as long. Thora.x

with four discal black spaces, the two basal

smaller. Black stripes of elytra regular pulcher.

Scutellum smaller, oval. Thorax with two broad,

discal, black stripes narrowly separated. Black

stripes of elytra with irregular margins BosensohcBldi.

B. pulcher Fahrs. Schonh. Gen. Cure, vi, 1, p. 310.

Form oblong, densely scaly. Head and rostrum shorter than the thorax,
densely covered with cupreous scales, a round spot black. Rostrum with
impressed median line, tip with feeble triangular impression. Thorax
broader than long, sides strongly arcuate in front, and gradually narrowing
to base, the latter slightly arcuate, disc moderately punctured, surface
densely covered with cupreous scales, and with four black spots; the pos-
terior smaller, sides of thorax cupreous, beneath the margin a black spot.
Scutellum transverse. Elytra oblong, moderately convex, with rows of
moderate punctures not closely placed; surface densely scaly, sutural inter-
val cupreous; a broad, black stripe slightly narrowed at its middle, and not
attaining the tip, at the side two oblong black spots, one humeral, the other
sub-apical, sometimes united in an entire stripe, limb and lateral vitta cu-
preous. Body beneath less densely scaly , scales pale cupreous, a black
spot at the side of the first two ventral segments. Legs less densely seal)',
femora nearly nude at apex and base. Tibiaj with short, spinulose hairs
within. Length .1C-.32 inch; 4-8 mm.

Two varieties occur. One has the lateral black stripe entire, in the other
it is broadly divided.

Occurs usually in the first variety in Florida, and in the latter in Texas.

This ftiinily is by fnr tlie liirj^cHt in tlic Rfijjnrfiophora, and tlierctort' ex-
hibits a greater range of viiriiilion in some of tlic important organs tlian
can be seen in tlie otlier families. Certain of tlie most remarltable diver
gences from tlie average type may, however, be separated as s\ib-familieH,
cxliibiting relationsliiiis with otlier families, without losing the essential
characters of this family ; that is to s.ay, the mandibles without scar, the
tarei with the tliird joint more or less dilated, not spinous beneath, the an-
tenna; with annulated or articulated club.

Of such sub-families I recognize five in our fauna ; all of very limited
extent, excei)t the C urculio iiidw (f/enuini).

They may be separated as follows :

A. Condyles of mandibles on outer side, motion lateral.

^landibles stout, feebly emarginate at tip,
with the inner edge sharp; gular pedun-
cle broad ; beak short, broad SITONID^.

Mandibles without sharp inner edge ; appa- ;

rently emarginate at lip, willi an addi- <

tional cusp:
Antenna; geniculate; gular margin ])romi-

nent, peduncle and mentum retracted. ALOPHID.ffi. .
Antenuiu straight, gular margin not promi-
nent; claws toothed (p. 130) ITHYCBRID^.

Mandibles varying in form, usually 3-toothed,
sometimes ol)lique without teeth*, gular
margin not prominent, peduncle usually
long (p. 131) OUROULIONIDiB.

B. Condyles of mandibles on upper side, motion

vertical (p. 321) BALANINIDuE.

Sub-family I. SITONID^.

The species of this sub-family have been heretofore classed with the
Otiorhynchide group Naupacti. They differ, however, essentially by
family characters ; the mandibles are short, very stout, with the outer side
convex, roughly punctured, and quite destitute of the apical scar which
indicates the deciduous cusp ; they are broadly emarginate al tip, and
the inner edge is acute. These insects are easily known from other Curcu-
lionida' by the mentum larger, more quadrate, slightly concave, and sup-
ported on a broad, but not long, gular iieduncle. The maxilkc are exjwsed
as in the lower Otiorhynchida;, and as in all CurculionidiC. and it tlierefore
seems singular that Lacordaire should have classed them with his Adelog-
nathes Cyclophthalmes, without noting the exception in this respect which
they mdkc in common with Gratopus and Elytrodon.\ The condyle of

* In De.wioris tlioy are also toothed on tlie outer edge as In KhynchitiUee.

SITONES Sch.

A few speries of this well-known ffenus occur in our fauna, and as will
be ol)served below, several of them are also found in Europe. They may

Sub-Family II. ALOPIlIDiE.

Tlie small group of Curculionidie, represented in Eurojic l)y Alophitu,
and in our fauna by several other genera, is sufficiently distinct in its oral
stru'-ture to warrant its reception asa suli-family. The convex oval elytra,
without humeral angles, and with tlie posterior part strongly deflexed,
added to the more or less rounded prothorax, give an apjiearance not unlike
ccrt.iin Otiorhynchidic; and the prolongation of the antennal grooves to
the tip of the rostrum, which is rather stout, increases the resemblance.

There are, liowever, radical differences in the mandibles; wliich are nearly
flat externally and punctured; pincershapcd, with a sharp e<Ige at the ajiex,
which is more or less emarginatc, and without apical scar or deciduous
piece. The menlum is tolerably large, trapezoidal and ll-'i, retracted witli
the gular peduncle, which is broad ; the p(>"terior edge of the latter ia
prominent, so that the iViOi.th appeafs hollow; the maxilhe are (ixposed, as
are also the ligula and i>alpi.

The beak is as long as the prothorax, rather stout, usually a little wider
at till, with distinct apical wings; the tip is feeblj' emarginate. and marked
also in the first two genera with a deep angulated impression, from which

transverse, narrowed below, and finely granulated. The antenna; are gcn-
iculated ; the scape long, the funicle seven-jointed (the first and second
joints longer), the club annulated, oval, pointed; the antennal grooves
usually long, well-defined, narrow, and reaching nearly to the lower angle
of the eye, except in Lophalopliiis, where they are wider and shorter. The
prothorax is distinctly lobed behind the eyes; the front coxae are contigu-
ous and prominent. The metiisternum is nearly as long as the first and
second ventral segments, and the side pieces are narrow; first, second and
fifth ventral segments long; third and fourth united equal to either of the
others. Legs motlerute in length, slender; tibia; truncate at tip, hind
pair not mucronate at the inner angle; tarsi dilated, claws entire, separate.

Our genera are as follows:

A. Beuk deeply channeled ; tarsi brush -like

glabrous, with a few scattered scales in the larger punctures, humeri
rounded, ftcutellum very smiill, pubescent.

Legs moderately long and slender, thighs somewhat clubbed, and sinuate
towards the tip; front tibia; subsinuate on the inner side, curved inwards
and mucronaie at tip; the other tibite are expanded somewhat at tip, trun-
cate and feebly mucronate. Tarsi shorter than the tibiie, claws separate.

T. ater, n. sp.

Black, nearly opaque i:^), or dull (9), beak and head strongly not
densely punctured; prothorax punctured towards the middle, coarsely
granose at the sides, with a narrow sometimes indistinct dorsal line; elytra
rugose and punctulate, with rows of larger punctures ?n which are scat-
tered pale scales; beneath witli small scittered patches of ochreous scales.
Length 12 — 14 mm.; .45 — .6 inch.

Califorpia: Dr. Horn anil Mr. Crotch. The patches of scales beneath
are on the prosternum in front of the coxa;; the outer angle of the melas-
ternum, and at the sides of the ventral sutures. This singular insect has
some resemblance in appearance to Moli/tes, but is more slender, and the
characters totally unlike. The elytra are more strongly declivous behind
than in the other genera, being in fact perpendicular towards the tip.

and the latenl grooves not so deep, there is also a vague groove between
the niudial and lateral grooves. Antenna; with the second joint of the

the second joint of the funicuUis is a little longer than the fii-st, as in
Alophus, and in all other respects it agrees with that genus,* The head and
prothorax are densely punctured, the latter usually channeled and carinate,
the anterior transverse impression strong, sometimes extending on the dor
Sill surface; the elytra are densely but more fluely punctured; the tarsi are
broad and scopiferous as usual.

The species may be thus distinguished :
Pronotum strongly transversely impressed near the tip;
dorsal channel strong in front, carinate behind:

Pronotum less coarsely punctured , 1. didymus.

Pronotum more coarsely punctured 2. oonstrictus.

Pronotum scsircely impressed near the tip:
Lateral groove of rostrum distinct; pronotum carinate

one-half longer than the head, antennal grooves wanting ; eyes small,
rounded, convex. Antenna; not at all geniculate. First joint scarcely
longer than the second ; third longer than the second ; 4-8 gradually
a little shorter and broader; club small, oval pointed, annuluted. Side
pieces of mesosternum diagonally divided ; epimera not attaining the
prothorax ; those of metasternum moderately wide, slightly dilated in
front. Ventral segments nearly equal in length; sutures straight, well
marked. Ffont coxte contiguous, middle coxa; narrowly separated ;
hind coxse transverse, narrow, attaining the side margin. Legs
moderate in length, slender, tibiae truncate at tip, with two small termi-
nal spurs; articular surface terminal, well-defined. Tarsi broad, spongy,
pubescent beneath; third joint deeply bilobed; claws divergent, armed at
the middle w'.th a small acute tooth.

Inner surface of elytra with tlie usual fold, commencing near the posthu-
meral sinuosity, running parallel to the margin as far back as the beginning
of the apical curvature; apical region very finely scabrous, with a narrow

the tender buds, as is observed by C. V. lliley (Third Report Ins. Inj.

berant, so as to bo visible from beneath, simulating a ventnil segment. We
owe the first accurate observation and explanation of this fact to Dr. Horn.
The pygidium is deeply grooved in both sexes, and projects beyond the
elytra.

Sub Family IV. CURCULIOXID^ (genuini).

The species of this sub-family may be recognized by the mandibles being
rarely emarginate at tip, but either bi-emarginate, with three apical cusjis,
or obli(iue, with three cusps on the irner side, which sometimes become
eflFaced, or obsolete. In the first tribei: the inferior cusp is also smaller, and
less prominent, but it speedily becomes more developed, and it is b\- the
final dominance of that cusp, with the edge of the mandible which corres-
imnds to it, that the oblique form with the teeth on the inner edge, is as-
sumed; and a still greater prominence of this inferior edge and cusp results
In the oblique or flattened form of mandible seen in certam Cryptorhyn-

chini and Jlarini. From them the transition is easy to the next subfamily
Balanlnid.L' in wliieh the mandibles are still more depressed, and the eon-
dyle instead of being on the outer side conies to the upper surface, so that
the movement is vertical, instead of horizontal as in all other Coleoptera.

It must also be observed that in certain P/u/tonomini the interior cusp
becomes very small or obsolete, so that the mandibles seem to be only
cmarginatc at tip. They thus approach the two preceding sub-families,
but are readily known by not possessing tlie peculiar characters whicl» dis-
tinguisli each of them. The beak is not short and flat, and the eyes arc
not round, as in Bitonidie; the gular margin is not prominent as in Alophi-
dic; and the antenna; are not straight, nor the claws appendiculate as in
Ithyceridie.

After eliminating tho tj'pcs which seem of sufficient imporUince to be re-
garded as hiving family or sub-family value, there still remains this vast
complex, whijii presents no difficulty in circumscription. It nevertheless
comprehends so many diversified combinations and representations of a
few simple cliaracters, and under each so many variations in a f(nv definite
directions, that much labor, and very careful observation is ne(!essary to
devise a sclieme which will enable the genera to be naturally grouped, and
easily recDgnized.

I believe Uiat the following table will be found sufficient for the proper
elucidation of our limited fauna, and perhaps with a certain amount of ex-
pansion and modification, may serve as a basis for a general arrangement of
the sub-family.

Tribe I. PHYTONO.MiBri.

Among the tribes in which the ungues are simple and separate, and the
pygidium not exposed, the present one may be distinguished by the form
of the mandibles, and by the hind tibiue being truncate at tip, with the ar-
ticular surface terminal, and though somewhat ol)lique, not latenil as in
Hylobiini. It follows from this that the terminal spine representing the
spur is situated on the inner side of the apical surface.

The mentum is oblong, and supported on a gular peduncle which is not
longer than wide, and emarginate. The ligula and labial pal|)l an; less de-
veloped than in Hylobiini; the maxillte are entirely exposed. The mandi-
bles are short, very stout, pincer-shaped, emarginate at tip, (except in Phy-
toHoinm opimm) convex and sparsely sculptured on the outer surface,
the basal condyle large. Antennae inserted near the tip of the beak, geni-
culate; scape long, club elongate-oval, pointed, annulated, covered with
sensitive surface; funiculus 7-jointed; the seventh joint in some species con-
nected with the club. Beak moderately long, not slender, antcnnal gro'^'cs
extending nearly to the tip, deep, dire'"'ed towards the lower par< of the
eyes, which are more or less transverse and narrowed beneath. Front coxaj

wider in front and more rounded on the sides, and the setas of the elytra
are much longer and more obvious.

This common European species occurs in Canada and in ^lassachr.setts.
It helon.s to Capiomonl's seventh group Phytonomidin*, in which the
first joint of the funiculus is much longer than the second, which is not
longer than the third.

rows upon the elytra. Beak as long as the prothorax, cylindrical, about
three limes as long as wide, glabrous, and nearly smooth at tip, which is
reddish-brown; feebly carinate; frontal fovea small, distinct. ICyes oval

in the foriii of the maiulii)le.H which are emarjtinate simply, as in I'lii/tono-

generic characters to separate it, except the less transverse eyes and the
oblique terminal surfaces of the tibiie. The habits of the species well

sent by Belfra^e. Tlie scales are, however, in great part abnuled, and
although I perceive some differences, I am unwilling to indicate it as
distinct.

MAOROPS Kirby.

The smaller species placed by Schonherr in Listroderes were separated
by Mr. Jekel as a distinct genus, IlyperodeH (Ann. Ent. Fr. 18()4, .ICG),
and undoubtedly the separation is a proper one. I find, however, that the
two species upon which Mr. Kirby founded his genus Macrops (Fauna Bor.
Am. 199), belong to the same set, and that name must therefore have pre-
cedence.

This genus is easily distinguished from the preceding by the til)ite being
stouter and less stronglj"^ mucronate at tip, and by the first joint of the
funiculus being stouter and as long as the second, except in M. soltitun,
where it is about two-thirds as long as the second; the seventh joint of the
funiculus is wider than the sixth, but is quite distinct in most of the species,
though in others it is rather closel}- connected.*

It will be seen that in the characters by which this genus differs from
Listronottis it api)roaches Phytonomun. Tlie greatest differences will be
found, however, in the proportion of the ventral segments, which in the
last named genus are not very unequal, while in Mdcropa the third and
fourth arc very evidently shorter, and together are not longer than each of
the others.

The species are closely allied and difficult to distinguish. The descrip-
tions of Bohenian and Gyllenhal, though minute, are not suflicient to
enable me to identify their species with reasonable certainty, and I there-
fore content myself with giving a list of those named in the books with
references, awaiting more abundant material and comparison with the
described types for a proper tabulation of the species:

EMPIIYASTINI.

In this species, whicli is easily known by the (leniided transverse black
spot, sometimes becoming a band, about the middle of the elytra, the sec-
ond joint of the funiculus is longer tlian the first, and the tibiiu are more
slender and more bent at the tip than in the others, thus establishing a pas-
sage to Listronotus.

Tribe 11. kmphyastini.

This tribe is evidently closely related to Iljilobiini, and agrees with it in
the structure of the mouth, but differs from it, as from all other tribes in
our fauna, by the peculiar form of the tibia;, which are fitted tor digging.

The front tibitB are compressed, slender, sub-sinuate, jjrolonged beyond
the articulation of the tarsus into a broad jjrocess, rounded at tip, and con-
cave beneath ; the spur is small and straight ; the middle tibia' are roughly
tuberculate and setose, with the apical margin repaiul, dilated on the
outer side, and armed with a straight fixed spur at the inner side: the hind
tibias are bent outwards, tuberculateandseto.se; much thickened towards the
tip, with very large and acutely margined corbels. Tarsi sparsely setose
beneath, and not spongy; third joint not dilated nor bilobed ; fourth joint
moderate in size, claws slender, simple and divergent.

The antenmeare geniculate ; funiculus 7-jointed; first joint longer ; 2-7
gradually broader, forming a perfoliafj stem uniting with the club, which
is oval, annulated and pubescent. Beak stout, shorter than the prothorax,
deeplj' grooved; antennal grooves extending to the eyes, which are small,
nearly round, and coarsely granulated.

Prosternum not emarginate beneath; front coxib contiguous, middle ones
slightly sei)arated, metasternum short, side pieces narrow, hind coxa' rather
large, oval, widely separated, extending to the elytral margin. Thighs
stout, unarmed. Ventral segments unequal; tlurd and fourth united ecjual
to the second or fifth; sutures straight, the first obliterated at the middle.

The above characters are drawn from Emphyastes. The Australian
genus Aphela only differs by the legs being less stout ; the tibia; less ex-
panded or thickened towards the tip, and by the beak not being grooved.

Sea Coast of the Pacific, from Alaska to San Diego; under sea-weed cast

Tribe IIL iiYliOBliNi.

The mandibles in this tribe have two apical teeth, of which the lower
one is a little shorter ; there is besides a cusp on the inner edge, so that
they becomes three-toothed. This normal form is preserved through many

of the following tribes, niocliflo«l only by the greater development of the
inferior I'di^e unci eiisp, which by assuming more prominence gives finally
an obli(iiie form to the mandible. The giilur peduncle is longer than wide,
a little wider in front, truncate anteriorly; the mentum is transverse, not
large, and the palpi are rather more developed than in the following tribes.
The beak is rather long, not slender, except in Pmodes, and the antennal
grooves do not extend to the tip. Eyes transverse. The antennte are
geniculate ; scape long, funiculus 7-jointed, club oval, pointed, annulated,
entirely pubescent and sensitive, except in Pmodes, where the first joint
is smooth and sub-glabrous.

The front coxt:;i are contiguous and the cavities confluent, except in
Pmoden, where they are slightly sei)arated. The middle coxie are not
widely separated; the side pieces of metasternum diagonally divided, with
the epimera triangular, not attaining largely the base of the prothorax.
Side pieces of metasternum narrow, slightly dilated in front. Hind coxae
widely separated, attaining the lateral margin, or nearly so.

Ventral segments unequal, first, second and fifth longer; sutures straight
and deeply impressed, except the first which is finer and sometimes
slightly sinuate. Pygidium covered by elytra.

Legs stout, or strong ; tibiie armed Avith a strong hook at tip ; articular
face lateral ; terminal edge of hind tibisu double, except in Pismdes; tarsi
with third joint dilated, spongy beneath ; claws simple, divergent.

The species are of moderate size, never very small, and are sub-cortical
in their habits ; they mostly infest coniferous trees.

This tribe leads directlj'^ to the Erirhinini, from which they differ chiefly
by the less delicately organized mouth, and generally stronger and coarser
structure, and by the double edge or corbel to the terminal margin of the
hind tibiiv. This character, common in Otiorhynchidre, now reappears for
the last time in the present family.

These corbels are very large and wide in Pachylobius, but narrow in the
other genera.

HILIPUS Germ.

This genus, largely develoiied in tropical America, is represented by a
single rare species found in Georgia and Florida. E.xcept that the spe-
cies of this genus are mottled with spots of very small white scales, not
hairs, and that the seventh joint of the funiculus is not connected wiih the
chd), the ditlerencos between it and Ilylobiiis are rather (comparative than
absolute.

The beak is cylindrical, and more curved, without anteocular grooves ; the
antennal grooves terminate at a greater distance from the mouth; the eyes,
postocular lobes and emargination of the i)rosternum are similar. The
thighs are efpially clavate, and sinuate beneath, but the tooth is much
larger and broader ; the tibiiu are compressed, bent inwards, equally
strongly armed with a terminal hook, but much less sinuate on the inner
side. The lirst ventral suture is deeper, and more strongly angulated at
the middle. The sculpture is much coarser and sparser, and the spaces be-
tween the large punctures are smooth and polished.

I am not satisfied with the position of this genus, and am disposed to
believe that it should be placed as a sejiarate tribe. Thomson (Skand. Col.

resemblance between the two. The definition of his tribe Pi»sodin<i does
not at all apply to Trachodet, in which the nietastenium is very short, and
the club of the aiitennie entirely pubescent and sensitive.

These insects live under bark of pine trees, and are sometimes very inju-
rious. Then; are evidently several species in our fauna, but the ditVerences
are not very obvious, and it is quite possible that a careful comparison with
foreign speiiies might reduce the number now recognized as distinct.

i ■' '

The diaracter which distinguishes this from all neighboring tribes, is
that the elytra are less extended on the flanks of the nietathorax and abdo-
men, so that the lateral angles of the first ventral segment become visible.

The body is never very stout, and freciuently is almost linear. The
gular peduncle is soiuetlmes short, sometimes long, enmrginate at tip ;
mentum large, flat ; ligula feebly or not prominent ; palpi much less de-
veloped than in llylohiini. Tibia; more or less macronate at tip; articular
surface lateral; ccn'bels wanting; claws connate at base, or at least approxi-
mate. Antenna; sometimes feebly geniculate ; joints of funicle gradually
broatlcr ; club elongate oval, annulated, pubescent and sensitive.

Tlie otlier characters are variable. Tlie beak is either short and thick,
or long and cylindrical; the tarsi are dilated and spongy beneatli, with the
third joint broad und bilobed, or only hairj', with the third joint shorter
and emarginnte. The first and second ventral segments are long and con-
nate ; in the elongate species the other segments are moderately long ; in
the species wi'h tiiick short beak they are shorter. The antenna; are in-
serted at a variable distance from the tip of the beak.

Sexual differences are not apparent in the short beaked species ; in some
of the elongate forms the beak is longer in the female.

Giiulational characters are observed in the form of the beak, antennte,
tarsi and daws, varying by almost insensilde degrees, so as to render ihe
classiticalion of this tril)e very difHcult. After several eflbrts, I am onl}'
able to offer the following table for the jdentification of the genera I have
examined:

Beak flat, stout, more or less grooved, somewhat dilated at
tip ; prothorax angulated on the sides near the tip, then
suddenly constricted. Antennic rather stout, feebly
gcnioiilated ; ventral segments !l-5 shorter than in the
sulisecpient genera. Tarsi usually not spongy beneath,

OLEONOPSIS n. g.

I hare been obliged to sei)arate as a distinct genus, one species found in
Texas and Colorado, which diflers from C7t'««i«.tby stouter and fiatter beak,,
the form and method of coloration, and by the joints of the funiculus of
the antenna\ 2-0 being nuire clo.scily united. It <liflers from StephnnMle-
onuH l)y tiie hind tarsi broader, the third joint not shorter, deeply bllobed,
with the lobes spongy beiu'ath. I cannot identify it with any of the
numerous genera nu-ntioned l)y Mr. Chevrolat, though it would quite
I)08sibly enter into one of tiiem.

OLEONUS Sell.

Allliougli the following si)eeies diJIer in minor details of structure, which
liy some entomologists are regarded as of generic value, there is such a
general resemblance in appearance and in the more important characters,
that it seems more natural to regard them as constituting one genus. I am
the more conlirmed in this belief from the impossibility of placing them
with any satisfaction in the groups established on the species of the other
continent, then\selves very indefinite in extent.

I would therctbre include under this head all the species in our fauna in
which the beak is stouter than in Lix%i», but not dilated at tip ; the gular
peduncle is not so broad and short !!s in the preceding genera, but is shorter
than in Lirm; there is a dillercnee )etween the species in this character,
it being longer in proportion to tiio increasing slenderness of the beak.
The front and middle tarsi are broad, ,'he third joint at least spongy and
bilobed ; the hind tarsi are liaiiy beneath in the first division, but broad
and spongy in the second. The gi'neral tendency of the pubescence is to
form longitudinal stripes, and not transverse or oblique bands. The body
is elongated, resembling Li.vii».

Our species may be thus tabulated :

The species of this genus arc generally more slender than those of
Cleonus, though not always. The tarsi are broad and spongy beneath,
with the third joint deeply bilobed. The beak is cylindrical, not thickened

nated, except in L. pleuralii and sylrius- The antennal grooves commence
at some distance from the tip of the beak. The antenna*, except in A. pleii-

and the second as long as the two following united ; in those two the funi-
culus is less elongated, less slender, and the second joint is somewhat less
elongated.

der, sometimes rather stout; the anteniial grooves coninience ul a dis-
tance froii.' the tip, descend ol)li(Hiely, and sometimes become continent
behind. The antennie arc geniculate, the scape long and slend<!r ;
funiculus usually 7-joint(!d, sometimes {Eitdulm) Ojointed; <'-.cii(r.al,
annulaled, entirely clothed with scnsitiv<,' surface except in Li-isorhoptun.
Prolhorax with or without postocular lobes; front coxte contiguous, pros-

Jletasternum usually long, rarely (I'fii/rorwteit) very short; side pieces
narrow, dilated in front. Hind coxie widely separated, transverse, nar
rower externally, and extending almost to the elytra! margin. Legs never
very stout, thighs usually simple, rnvvW (Dori^lomuit') toothed; tibiie trun-

This j^enus contains those species of Erirhiimn in which the i>rostcriium
is deeply emarjrinate in front, and the j)ostocular lohes Itrond and distinct.
The hind liliise are leelily mucronate, and have in addition two very small

new one closely allied. In well preserved spee-imens liie pulie.sc<-nce is
very coarse and mottled in color. The posterior callus of the elytra is
somewliat distinct, but by no means sulHc-iently so to warrant Manner -
Jieim's expression, "eli/lriH ante npireni atrinque tuhercido inxtni.ctiK."

Two smaller specimens from Alaska have the thorax less rounded on the
sides near the tip, and in one of them there is a distinct smooth, narrow,
dorsal vitta; they were sent to nu' as h'rir/n'nn.K rextitiin Mann., a very dif-
ferent species, which has the lieak pimclureil but not striate.

Four specimen.s of small size were collected by Mr. Crotch in the
M(*jave Desert, Cal., which I would teini)orarily refer to this sju'cies.
They are yellow brown with a broad darki'r stripe on each elytron They
agree in form with the Eastern specimen, and are a little more robust than
those from Alaska. Length 2.5 mm; .10 inch.

A larger series of well-i)reserved .specimens will perhaps show the pro-
priety of receiving these three forms as distinct species.

Group II. Demnorhlne*.

In the genera constituting this grou)) the beak is slender, and separated
from the head by a sharply defined transverse line, or constriction. In our
genera the claws are connate at base, but as this character is not mentioned
in the Kuropean genus Sharpiii (Tournier, Ann. Ent. Belg. xvii,; and is
somewhat variable in Smicron^.i;, I do not know that it is properly of
groui) value. The mandibles are truncate at tip, and toothed both on the
inniir and outer edge as in Ilhynchitidie. The prosternum is emarginate
in front, and the ventral sutures are very slightly curved at the sides. The
antennal grooves descend obliquely and are almost confluent behind.

DESMORIS n. g.

This genus corresponds closely with Krirhinun, except in the ditlVrences
Indicated in the definiticm of the group, viz., the connate claws, the
obliipie antennal grooves which ate nearly confiuent behind, and the beak
constricted at base. The second joint of the funicle is as long as the
first, but more slender. The thighs are clavate, unarmed. The tibia'
slightly mucronate and trunc^ate at tip, nearly as lon.^ as the thighs ; tarsi
dilated, third joint deeply bilobed, fourth joint long; claws small, ((mnate
nearly to the tip.

The api)earance is that of Balaninus in miniature, the eyes arc rather
large and transverse, the sides of the prothorax .scarcely lobed, and the

SMIORONYX Sch.

This genus contains small species which only differ from I'urhi/tt/rhiuH
by the second joint of the funiclo being shorter than the lirst, and
frequently not longer than the third ; the scape reaches to tl'.e eyes. The
postocular lobes of the protlnu'ax ant sometimes distinct, and tlie prosler-
num is moderately einarginate in front. The beak is shorter than in
DeHiiiorin, and is slightly thicker at base ; the transverse constriction is
well defined, and the pubescenc(; at the i)ase of the beak rises into two

tuns.

The form varies somewhat, the first species rese?nbles Piirfii/lf/rhiuK by
the strongly rounded sides of protiiorax and ovate tdytra ; otiiers resemble
in miniature Bori/loinan, but the thighs are noltoothe<l, and the claws are
small and connate almost to the tips. Others again have tint claws approxi-
mate, but s(;arcel3' connate.

The genus, even as thus defined, s(!ems to me somewhat heterogeneous,
and with more careful study will be found jierhaps, to contain (dements
representing other Kuropean genera. Il ^\•\\] iu; for future investigators to
determine if our species shall be partitioned, or the European forms con-
densed.

The species are difficult to define, and the table given is not very satis-
factory.

Second joint of funide of antennic not longer than third ; claws

connate for more than half the length 2.

which are broad o\al. The prothorax is thi(,'kly punctured, and distinctly
constricted near the tip. The elytra are comparatively longer and less
convex than in the neighboring species, thus producing a resemblance to
Dovytviims.

Kansas ; one specimen . A very small species, related to S. (yrJdouhs,
and easily known by tli(! narrow scales and rounded sides of the protliorax.
The scales are partly abraded, but ajjpear to be mottled in color.

Group III. Eiiisnoiiil.

Following the example of Lncordnire, I recognize as a distinct group f
small number of genera -which are closely related to the Krirhini proper,
and like tlu'm have the antennal grooves directed against the eyes ; they
diffcir in having the eyes larger and more prominent, and separated from
the margin of the protliorax by the head being more or less prolonged be-
hind. Tile head thus recalls the form already seen in Rhinomacer and
lihynchiteK, though otherwise there is no resemblance.

The two sj)e(,'ies in my collectioi. resemble in appearance small Dorytomus
but the thighs are unarmed, and the second joint of the funicle of the
antennie is sliort.

I will for the present refer them to the genus Phyllotrox, though they
ditl'cr from the description given by Lacordaire (Gen. Col. vi, .jOo), by the
first veniral suture being well-marked.

Beak rather stout, nearly as long as the protliorax, punctured, feebly
channeled from between the antenna' for a short distance; eyes rather large,
liromineiit ; antennaj yellow, with the scape reaching to the eyes. First
joint of funicle stout, and inoderately long, followed bj- six short joints,
club oval, pubescent. Protliorax not lolied behind the eyes, longer than
wide, narrowed in front, feebh rounded on the sides, slightly constricted
near the tip, rather densely i)unctured, thinly clothed with shining jellow
hair. Elytra wider than the i>rotliorax, elongate, humeri rounded, strite
with dose-set punctures, intersiiaces densely ininctulate, and sparsely
pubescent, brownish-yellow, with the scutellar region and fre(;uently the
suture d 'rk. Body beneath dark, strongly punctured ; abdomen and legs
brownish-yellow. Thighs not toothed, rather thick ; tibia; stout, truncate

This genus was first described by Scluuilierr, under the previously used
name Notiophilus. The error was recognized and corrected in Vol. vii of
his work, and the name changed to JVotiodes. Meanwhile, however, En-
dnlus had been proposed by Laporte, in a systematic work, and being ac-
companied by proper description must of course take precedence. The
species occur on grasses near wafer ; of those described thus far, only one .
properly belongs to the genus, the others will be found under Oni/rhi/lis
and Li.isorho2)trus. The funiclc is G-jointed, and in some of the s])eeie9

Two smaller specimens are entirely similar to the preceding in form and
sculpture, the elytra are covered with dirty gray scales, with a large com-
mon discoidal dark brown spot, extending from the base for four-fifths of
the length, with prolongations on the third and fifth interspaces, causing
the outline to be irregular; there are also two clouds on the sixth inter-

Schunherr for changing the name under which he first delined this genus is
uot a valid one. Even if there wi'fe in Dejean's Cataloirue a genus Stciiop-

Though the three species described below, do not exactly agree with the
generic description given by Schonherr and Lacordaire, I think tluit they
accord sullicienlly to indicate th<' propriety of associating them together as
a special group.

As hero estaiilished, the J]r(ifJti/pi i\ix' nearly related to ITiidronomi, but
ditVer by tin; third joint of tlu^ tarsi being more or less bilobcd, and the hind
tiliiie triuicate at tip, not unguiculate, but only feebly nuicronate, with
the articular surface terminal. The tarsi are either broad or narrow, the
third joint sometimes but little dilated, and the last joint long, with large
divcrgci, ' iws. The body is narrow, covered with a dense water-proof crust
of scales, as in G rypto pi I i\m\ Hydronomi. The beak is straight, cylindri-
cal, moderately stout, and as long as tlu: prothorax ; the antennal grooves
run directly to the eyes and converge but slightly behind; they commence
at a varying distance from the mouth. The autennfc are slender ; funi<le
7-joiiited, first and second joints elongated in our genera, :'-T gradually
broader, club oblong-oval, annulated, entirely covered with sensitive sur-
face. Prothorax with large postocular lobes, presternum deeply cmarginate
beneath, not excavated. T^egs long, slender, thighs moderately clavate,
front and middle tibia' slightly sinuate, feebly muerouate at tip.

LIXELLUS n. g.

A small species of still narrower form constitutes this genus. It has pre-
cisely the appcMiance in miniature of a slender LixuK, and dilVers from
Aiicliodonun by the third joint of tlie tarsi licing not wider than the second,
and not bilobcd ; the fourth tarsal joint is as long as the others united, and
the claws are large and divergmit. The thighs are less clavate, the tibioc
strongly bent, and the front and middle pairs are serrate on the inner edge
from the middle to the tip ; they are all feebly mucronate at tip. The beak
is shorter than the protliorax, rather stout, nearly straight, and the anten-
nal grooves commence near the tip ; the funiculus is (i-joiiited, with the
tirst and second joints longer, the joints 3-0 short, slightly wider, club

Group VIL HydronoMil.

The same varnish-like covering noticed in the three preceding groups is
retained in this, the species of which are also found on plants near water.
They arc easily distinguished by the longi'r and more slender legs, the; tibitc
curved, and frcquentl}' serrate on tlie inner side and strongly hooked at tip.
Tlie tarsi are usually slender, the third joint frequently not dilated, and
the last joint moderate or very long, with stout, simple, divergent claws.
Tlic prosternum is usually broadly sulcatc.

Our genera may be tabulated as follows :

" " partly sniootli and shining ; pros-

ternnni not exeavated LISSORHOPTRUS.

3. Proihonix feebly constricted in front BAGOUS.

" very strongly constricted in front. ... PNIGODES.

LISSORHOPTRUS n. g.

This is the genus indicated without characters, and not named by Laror-
daire.* It is founded upon Biifjoiix Kunplcx Say. It dillers remarkably
from the other genera of the group by the antennsr, the club of which is
smooth and shining for two-thirds the length, and aiinuiatedonly near the
tip ; the funiculus lias but six joints, of which the tlrst is stout, and the
second a little longer than the otliers, which increase slightly in thickness.
The jirosternum is flattened, not excavated, transversely impressed in front
of the coxic, wliich arc very large; ; tibia! not very slender, somewhat
curved, armed with a terminal book. Tarsi narrow, last joint as long as
the two preccnling, claws slender, approxiniate. Beak stout, as long as the
prothorax. Antennal grooves suddenly dellexed.

This is again a genus of transition, and onl}' dillers from 0 n i/ch ylia by
the third joint of tarsi not emargin!it(>, by the peculiar antennal club, by
the tibia' armed witli stronger terminal hook, and the articular surface
even of the hind pair lateral.

Southern States and Texas. Only differs from the prcci-ding by the
usually larger si/e, and by the transverse impression at the middle of the
sides of the prothorax being wanting.

BAGOUS Germ.

The essential characters of this genus consist, in my opiniini, in the tibiti,'
l)eing slender, strongly curved and armed at the tip with a strong hook, so
that the articular surfaces !)(■■ ome lateral; the tarsi are narrow, not spongy
beneath, though the third joint is sometimes wider and emarginate. The
claws are divergent, sometimes rather large. The club of the antenuiB is
entirely pubescent, sensitive, and larger than usual ; the antennal grooves
are deej) and extend to the cy<;s ; the beak varitjs in form. The prosicr-
num is broadly and dee[tly excavated in front of the coxte, and the groove
is sharply limited at the sides by ridges ; the postoeular lobes arc; large.

This new genus is closely related to Bar/om, and has the prosternum
similarly excavated. There is also no ditl'erence in the beak, which is stout
and curved, nor in tlu; antennie, which have the funicle 7-jointed; Ibo
first joint is stouter and the second longer than the others, which increase
gradually in thickness, and the cluli is pubescent and annulaled. The legs

The form of body is, however, remarkable. The prothorax is wider
than long, narrowed behind, widely lobcd on the sides before the middle,
then suddenly and very strongly constricted and tubulate. The elytra are
■wider Uian the prothorax, with the alternate interspaces elevaicd, and a

Tribe VI. TRAt'HOWlNI.

The genus Trnc1)odcH, which occurs in Europe, Asia and Alaska, ditfers
sutlicientlj' from all others in our fauna to merit being jjlaeed in a separate
tribe. Lacordaire classed it with the Moli/flni, which however seems an
unnatural grouping of genera agreeing only in convex body, short meta-
sternuni, and absence of wings. The beak is rather slender, as long as the
prolhorax; the antenna' are inserted a little before the middle (9)i f*'" ""e-
third from the end (f ), rather slender, the scape reaching the inferior
margin of the ej'cs, which are nearly round, coarsely granulated, and
somewhat removed from the jirotliorax; lliefunicu!;isis7-jointed, lirst joint
elongate and stout, second nearly as long, but slender, -V-l sliort, slightly
increasing in thickness ; club rounded oval, about one-half longer than
thick, annulatcd, pubescent, tip rather i)ointed. I'rothorax scarcely lobed,
hut ciliale behind the eyes. Ei)imeni of metatborax narrow, entirely cov-
ered by the elytra; hind cox;e rounded, widely separated, not attaining the
elytral margin. Ventral segments, tirst and second large, each as long as
the metasternum, separated by a straight suture which is deeply impressed
at the sides; third and fourth short, sutures straight; fifth as long as the two
preceding united. Legs rather long, thighs pedunculated, not toothed ;tii)itc
slender, strongly hooked at tip; tarsi rather long, third joint wider, bilobed,
last joint elongate, claws simple, slender, separate. Body rough with short
erect bristles.

TRAOHODES Germ.

Elytra uniformly convex without elevations:

Bristles of elytra not tufted 1. ptinoides.

Each elytron with two tufts of bristles 2. quadrituberculatus.

bunches of bristles; they are situated on the third interspace; the first is
about one-fifth from the base, and the second a little behind the middle; the
elycral striae are rather finer than in the preceding.

Tribe VII. oTinocEPiiAi.iNi.

In all Iho preceding trihcs the tarsal claws are simple, usually separate
and divergent, rarely connate ; in this, as in several of lliose wh.cli follow,
they are toothed ; tiic tootli, however, is broad and not very i)roniinent,
giving the form termed ai>pendiculate. The species are easily known from
those of other tribes by the protlKU'ax being narrowed at base, an<l somc-
wliat pedunculate. Several of them arc shining black and glabrous, so
that thoy resemble in appearance ants.

5Ir. C V. Uiley, who has hatched several specimens of Otitlt'cephnii.t htcin-
coUis from the galls of Cijnips r/Hiirriis-f/lohnluH, informs me that they have
a gfMieral resemblance to an ai)ten)us Ci/nips.

The other characters of the tribe and genus are as follows ; Beak
rather stout, straight, nearly as long as the prothorax, subcylindrical,
not emarginate at tip; antennal grooves extending in front of the inser-
tion of the antenna', converging behind, directed below the eyes, which are
distant from the prothorax, rounded, and tinely granulated; matidibles of
normal form, mentum and labial palpi small, gular peduncle narrow,
long; antenn;e inserted about one-third from the tipof the l)eak, scape long,
slender, extending to tlu; back part of the eyes; funicle 7, jointed; first Joint
stouter but only slightly hmger than the second; 2-7 gradually a little
wider, rounded ; club oval jioinlcd, pubescent, feebly anmdated. Pro-
thorax without postocular lobes; i)rosternum broad, short, not i.-marginate.
^Mesosternum very narrow between the coxie, side pieces almost longitudi-
nally divided. ]Metasternum long, side i)ieces very narrow. Ventral seg-
ments nearly equal, sutures straight, well marked, iutercoxal process obtuse,
moderately wide. Front coxiu rounded, i)rominent; middle coxiu rounded
not prominent; hind coxie oval, not extending to the elytral margin.
Legs rather long, thighs smne what clavate, usually toothed; til)i;e truncate
at tip, not mucronate; articular surface terminal; tarsi dilated, spongy
beneath, third joint broader, bilobed; claws divergent, more or less toothed.
Elytra elongate-oval, convex, rounded at tip, entirely concealing the
pygidium.

The larva lives upon the kernel of the plum, like Cunotrachelmt nen-
uphar. Mr. liilcv inl'orms nu; that he has n^ason to believe that ihe eijfiis
not pushed by tlie lieak of the female deep into tlu; fruit, as is tlie case
with that species, but i.s laid on the surface, whence the larva, when tirst
hatched burrows to the seeds.

Mr. Walsh veiy pni|)erly suspected that this inseci should he separated
as a distinct ge'ius. 1 rejirel to iiave led him into error by not recogiuzing
the species as ideiitieiil witli my previously descril)cd A. neiitdlariH, which
waa founded upun a much smaller specimen from a far distant locality.

ANTHONOMUS Germ.

The species of Ihis genus are quite numerous, and although agreeing in
the more important character.*, diller in such nuvnner as to indicate the pro-
priety of future subdivision. For the purpose of making these subdivis-
ions natural, a profound study of the exotic species will be necessary. I
can at present merely mention .some of the variant structures which I have
observed.

The presternum varies in length, being shortest in A. elegans, and long-
(ist in A. rufipcH and clonrKituK. The fifth ventral segment is not longer
than the fourth in most species, but in A. elomjatuK and some others of
Division B it is quite distinctly longer and flatter, as in Erirhinini, and
in these species the jn'gidium is not exposed. Tlu; ventral sutures are
straight in most species, but the third and fourth are slightly curved in A^
conjnnctuH, which thus shows a tendency towards Tychius. The claws are
usually cleft, or armed with a long slender tooth; in certain species, as will
be .seen in the followinir table, the tooth is broad, or even so obtuse as to
be indistinct. The funicle of the antennaj is usually 7-jointed, but in the
sj)ecies of Division C only six joints are observed.

These characters seem to be similar to those used by Lacordaire for sep-
arating the genera of -4?i</K>/w»HVii", (Gen. Col. VI, 577), but on referring
to the detailed descriptions, it will be found that in other respects the spe-
cies in our fauna disagree. I, therefore, deem it more expedient to place
them all in Anthonomus. The following table will enable most of them to
be easily recognized.

The color is black, with the antennae and tarsi testaceous; the front
thighs are armed with a very small tooth, and the others are entirely un-
armed. The markings are composed of scales, and in well preserved spe-
cimens the sides of the prothorax and the trunk arc also scjuaniose; a small
post scutellar line and another each side at the base, and an indistinct pro-
thoracic dorsal line arc also whitish. The elytral markini^s stop suddenly
at the eighth strisc, along which the front marijin of the curve is prolonged,
thus giving an oblique outline. The color varies and tliL elytra and legs
are sometimes dark brown. I am in doubt whether tiiis species is properly
identified with the one intended by Gyllcnluil. If tW. latter be not the one
licre described, it is probably nothing more than a dark variety of the nc.\t
species, A. suhguttatus, described below, also agrees moderately well, but
the elytra are not piceous and the beak is not striate. If on examining the
original tj'pe of sciitelkitiis it is found that this species is distinct, it may
be called variegatim.

Massachusetts to Florida and Texas ; the black sjwt usually extends from
the side two-thirds way to the suture, upon which in the best marked
specimens, there is also a small dark spot ; but it is frequently much
smaller, extending onlj' from the third to the sixth stria ; the pul)escence
is denser at the margin of the spot which is thus surroimded with a hairy
band. The thiglisare all armed with an acute tooth. The .second joint of
the funiculus of the antenna' is perceptibly longer than the third, but not
so much so as in the jireceding species. It therefore forms a passage to
the small species which compose the next gioup.

10. A. rubidus, n. sp.

pubcEcence; beak punctured and striate, head sparsely j)unclured; i)ro-

tip, pubescence more condensed on the median line. Elytra one-third
wider than the prothorax, oblong, striie deep, modtiralely jiunctured, inttu'

12. A. sycophanta Walsh, Proe. Ent. Soc. Phila., vi, SCm.

"Western States, Illinois; ]Mr. Walsh. Breeds in galls on willow trees.
This sjiecies is easily known by the intersijaces oif the elytra rather flat,
and nearly oi)a(|ne; the punctures of the ])rotlu)ra.v are very coarse and
crowded. The pubescence is hairy above, but coarser and almost scale-
like beneath, the beak is punctured and striate; the thighs are all armed
with a tooth, and tlie front tibia' are nearly straight. The color varies,
but the elytra are always red, though sometimes darker near the scutelUim.

T am disposed to helieve this is .1. iKvmdtonun Boh. Sch. Cure, vii, 2,
22'2, with the description of which it agrees in all particulars, except that
th(! i)rothorax is not "rugom f/raiinhtti)," a style of sculpture very unlikely
to occur in the genus, but which may be a vague method of indicating the
very coarse deej) punctures with narrow high intervals which characterize
this species.

though less so than in the preceding species; elytra oblong, humeri less
prominent than usual, and rather obli(iue, strise well impressed, coarsely

the red elytral spot, which is sometimes bright yellowish-red, and distinctly

blackish. In one specimen the surface of the elytra is dull and finely ru-

the early stages of development, and must be regarded as an accidental
monstrosity, aiul not as a variation.

When the scales are rubbed oil' a tine inconspicuous puhescence remains.
The emargination of the i)rosternuni gives an appearance of feeble post-
ocular lobes, and in following Lacordaire's arrangem(;nt this genus would
be placed in the Ceratopides, after Acdnthobruchium, from which it scem.s
to ditler by having only the front thighs toothed.

ALYOA n. g.

I have separated as a distinct genus Erirhinus epJiippiatim Say, which
ditfcrs from the other genera of this group by having the last ventral s(;g-
mcnt as long us the two preceding, and the claws divergent and broadly
appendiculate. The beak is not very slender, cylindrical, as long a.s the
prothorax ; the antennic arc inserted aliout one fourth from the end ; tiu;
scape attains the cN'es, wiiich an; roundeil, moderate in size, and distant ;

CUnCULIONID^.

[lieConte.

Atlantic slope; found also hj Mr. Crotch at San Diego and San Bernar-
dino, California.

A small yellowish-brown insect, densely clothed with yellow pubescence,
with a large dark spot near the base and another transverse one beJiind the
middle, connected by a suturul stripe; sometimes there is an appearance Oi"
a third spot near the tij) of the elytra.

This insect might be easily confounded with some of the varieties of
Phyllotrox nubifcr, but the elytra are less broadly nunded at tip, and the
claws are not simi)le, but broadly appendieulate. It varies greatly in size,
1.8-2.9 mm.; .07-.11 inch. Bred by Mr. Walsh from a CecidomyidouB
gall; S. brasaicoides of tialix lonyifolia.

Tribe X. PRio^roMKRlMi.

This tribe contains a few small species of robust form, easily known X^y
the following assemblage of characters :

Beak stout, sometimes short and flat: antcnnai inserted about the middle,
scape extending upon the eyes which are large and rounded ; funicle
7-jointed, club very large, pubescent, oval pointed, almost articulated.
Protbora.v without postocular lobes, front coxte contiguous; prosternum
short, not emarginate.

Ventral sutures deeply impressed; the first is straight, the others strongly
angulated at the sides; fifth segment scarcely longer than the fourth. Legs
stout, tibiie with a slender terminal hook ; tarsi dilated, spongj' beneath ;
third joint bilobed, claws appendieulate, Pygidium more or less visible.
Beak as long as prothora.K. sub-cylindrical; long; front

tiiiglis with a large serrated tooth Prionomerus.

Beak short, broad and flat; thighs with a small acute

tooth Piazorhinua.

middle on the under r-idc; this tooth has been overlooked by Schonhcrr,
while Lat'ordaire describes the thighs as unarmed.

2. P. pictus, n. sp.

Testaceous, clothed with pale-yellowish pubescence ; head and beak
dusky. Elytra with a large ro'intlfd common dusky spot extending from
the base to the middle, paler within ; and a dusky oblique band, more or
less interrupted on the seventh interspace, which attains the suture about
one-fourth from the tip ; striie jiunctured, less deep than in P. scutsllaris.
Thighs armed with a small acute tooth ; claws appendiculate. Length
2.5 mm.; .10 inch.

Georgia; one specimen. The large C(mimon spot of the elytra is dark
only at the edge, in the middle it is nearly as pale as the ground color. A
manuscript drawing by my father named Arhynchus to)nentom3\ Da].
Cat. resembles this species.

Tribe XI. tychiim.

In this tribe a form of body is resumed, wliich resembles ihat of the
Erirhinini. The claws, however, are not simple, but appendiculate or
toothed, and the second, third and fourth ventral sutures are not straight,
but strongly angulated at the sides. The prolongation backwards of the
side angles of the second segment is in some genera carried to such an
extent that the points reach the fourth segment, and the sides of the third
segment are thus entirely covered. The pygidium is usually exposed,
by the tips of the elytra being separately rounded, but in I'ychitis they are
conjointly rounded, and the lygidium is covered. This character, as in
Anthonomini, possesses, there ibrc, but little value. The ventral segments
are less unequal than in Erirhinini.

The other cliaracters are those common to the preceding tribes ; Beak
long and usually slender; antenufe inserted far from the tip; antcnnal
grooves direcied sometimes against the eyes, sometimes below them.
Th(! eyes are rouniied or nearly so, not finely granulated. The funicle
of the antenna' is 6- or 7-joiiited, and the club entirely pubescent and
annulated. The prothorax has no postocu'.:r lobes; the prosternum is short,
not strongly emarginate in front, and the eoxoj are contiguous. Tiie side
riieces of \\\c mesotliorax are diagonally dividtjd, and the epimera do not
largely attain the base of the luothorax. Th-.: metasternum is long, and the
Kide pieces are narrow, or moderately •'vide, dilated in front. Tibiie feebly
or strongh' nnicronatj; articular surOvi >rolonged on the outer face, so as
to bectuie oblique.

PROCTORUS n. g.

This new genus is established upon a small insect whicli has altogether
the form, sculpture, and mottled pubescence of Erirhinus; it is, however,
easily known by the stouter beak, the curved ventral sutures, and the
broadly appcndiculate claws. The se.xual characters of the -^ are very re-
markable; the fifth ventral, namely, i.s a.s long as the three preceding uni-
ted; it is divided by a transverse sharply elevated ridge into two jiarts, of
which the anterior is the larger and broadly concavtr, the binder part is
much more deeply concave, and on taoh side atthi^ jnnoi j'-'!1 of lite elevated
ridge with the margin is a stout, tlattcned horn, voundcii .it the tip; on the
anterior margin of the segment, at the middle, i.s a third .shorter horn.

Beak as long as theprothorax, rather stout, cylindrical, somewhat curved,
densely punctured, not striate nor carinate. Antenuic inserted about one-
fourth from the tip (?)or less (r^); scape slender, reaching the eyes, which
are rounded and distant; funicle 7-jointed; first joint as long as the two
following, and stouter; 2-7 short, equal, gradually a little wider; club
moderate in size, elongate-oval, subacute, anuulated; ante.unal grooves
reaching the lower margin of the eyes. Prothorax about as wide as long,
rounded on the sides in front, and feebly ■nipressed near the tip. J^lytra
wider at base than i)rothorax, elongate oblong, humeri prominent, rounded,
sides parallel; marginal stria incomplete at the nnddle. Ventral segments
unequal; third and fourth together scarcely longer than each of the others;
first suture straight at the sides, arched forwards at the middle; otlior su-
tures angulated at the sicies. Legs rather short, thighs not 'iiotln,'d;
tibise straight, the front pair with a small terminal hook; tar wii'. tlu ii' ;t

ENCALUS n. g.

This genus also resembles a small Erirhinus, and differs from Proetorun
only by the beak being longer than the prothorax, and more slender; it is
also punctured and feebly striate towards the base, as in many Anthonomi.
The antennae are inserted about one-fourth from the end of the beak; the
scape almost reaches to the eyes, which are moderate in size and distant:
the funiculus is 7-jointed, first joint longer, the others nearly equal, short,
gradually wider and more rounded; club oval, annulated; ventral segments
unequal, third and fourth together as long as second, fifth nearly as long;
first suture straight; others angulated at the sides. Legs moderate, thighs
armed with a small tooth; claws divergent, broadly ajipendiculate.

I.E. decipiens n. sp.

Tilack, clothed with white and yellowish pubescence. Prothorax not
wider than long, broadly rounded on the sides, coarsely and very deeply
J 'nctured. Elytra wider than prothorax, at base elongate oblong, with a
■•• )ad transverse blacK. band occupying the middle third; stria; coarsely
punctured, interspaces fiat. Antenna; and legs piceo-fcrruginous. Length

hears an almost deceptive resemblance to Macrops solutns, but in other
characters it is in every way dilferent.

PLOCETES n. g.

Beak rather stout, as long as the prothf)rax, carinate, punctured and with
three fine elevated lines each side; antennal grooves deep, extending to the
lower margin of the ej-es, which are oval and rather large, i ntcnna' in-

■wider than long, rounded on the sides, narrowed in front of the middle,
neither lobed nor constricted in front. Elytra one-half wider than uroi bo-
rax, humeri oblique and rounded, disc not very convex, posterior callus
mther prominent. Abdomen rather fiattened; first ventral suture straight;
the others distinctly angulated near the sicies; thirti and fourth segments
very little shorter than tiie first and second; fifth about one-half longer than
fourth; pygidium covered. Legs rather stcmt, thighs clavate, with a very

suture is velvety black, contrasting well with the diftused brown tint into
Avhich the band fades towards the tip of the elytra.

This curious insect Is suggestive of a very small Finsotles, with Mhich,
however, it has no relations beyond the mere superficial resemblance in
form and sculpture.

THYSANOCNEMIS n. g.

scarcely increasing in width; club rather large, elongat(!-oval, very dis-
tinctly annulated. Prothorax wider than long, narrowed in front, and
feebly constricted, broadly rounded on the sides. Elytra nearly one half
wider than the prothorax at base, oblong, slightly narrower from the hu-
meri, Aviiich arc prominent and rounded. Ventral segments unequal; first

TYLOPTERUS n. g.

This genus Is established upon two .small species from Texas, clothed
with remarkably dense sericeous pul)csceiice, and having small tufts of hair
and very i)rominent elytral callus. The beak is slender and curved; the
eyes large; the front narrow (about one-third as wide as the beak). The
antenn.'i' are inserted about one-fourth from tlie end of the beak, slender; the
scape reaches the eyes; funiculus 7-jointed, first joint as U)ng as the two fol.
lowing; second joint a little longer than th<> third; club elongate-oval, annu-

behind; posterior callus very prominent. Ventral segments sube((Mal, ex-
cept the fifth, which is as long as the two preceding united; first ventral
suture siraight, others angulated at the sides, but the second more so than
the third, so that the angles of tlie second segment project over the third
nearly to the fourth segment. Pygidiuni of 9 nearly covered by the elytra;
anal segment of f^ large, defiexed, and convex. Legs rather long, thighs
clavate, not armed, front til)iie longer, more slender, and slightly sinuate in

form of a large obtuse tubercle, causing the declivity to appear broadly con-
cave; marVed with two irregular transverse bands of brown hair, the pos-
terior one in front of the callus, and narrowed at the suture; the front one
commencing at the middle on the sides, and running obliquely backwards
to the suture, where there is a narrow tuft of black hair occupying the first
interspace for one seventh of its length; small pencils of black hair are also
seen on the third, fifth and seventh interspaces where the bands cross them;
there is also a little tuft on the third interspace near the base. Atitennnj

TYOHIUS Sch.

The few species of this genus thus far known in our fauna have the funic-
ulus of the antenna) 7-jointed, with the exception of 7'. setosm, which
may perhaps be hereafter recognized as generically distinct; they resemble
in form Ventrinus, though the contiguous front coxffi and toothed claws will
enable them to be immediately distinguished.

It is worthy of remark that the first observation concerning the anal seg-
ment of the ^, is recorded by Mr. Brisout de Barneville.* Had the impor-
tance of this observation been recognized, and its limitations inquired into,
much of the labor 1 have devoted to the study of the llhynchoi)horous series
would have been saved, and our knowledge concerning the classitieation of
these insects would be much farther advanced, f

species with tiie one described by liim as T. aratus; and Major Gylh^nhal
suspecting perhaps the existence of some error has, while quoting Say in
synonymy, given a different name to the insect received from that author.
Although of the size (3.3 mm.; .13 inch) and form as T. anitm, it is
quite distinct by the beak narrowed from the base to the tip, less distinctly
channeled, and more densely pubescent; the covering Is of fine narrow
prostrate hair-like scjiles of a uniforni pale dirt color, and the hind thighs
are distinctly toothed. 1'. aratus is unknown to me, unless it be T. tectus.

SIBYNBS Germ,

I refer to this genus a small species from Lower California which differs
from the others of this group by the elytra being separately rounded at tip,
thereby exposing a large part of the pygidium. The funicle of the an-
tennaj Is C-jointed; the first joint is elongate, the second a little longer than

PARAQOGES n. g.

A curious little species from California constitutes this genus. Tt has all
the essential characters of Tj/rhiua, ex(H>pt that the pygidium is somewhat
cxi)osed, and the claws are small, sin\ple and api)roximate. The beak is
longer than the prothorax, cylindrical, nearly straight, and rather slender.
The antennal grooves descend obli(]Uely below the eyes, which are small,
rounded, and coarsely granulated. The funicle is (l-jointed; first and second
joints longer, the first being stouter; :?-() gradually a little broader, some-
what rounded; club oval-pointed, pubescent, annulated. Protliorax as long
as wide, constricted near the tip, without jiostocidar lobes. Ely'ra oblong
elongate, wider than the prothorax, separately rounded at tip. A.igles of
second ventral segment prolonged as far as the fourth segment. Legs mod-
crate, thighs not toothed; tibia' oblicpiely truncate at tip, scarcely i)ercep-
tibly mucronate; tarsi spongy beneath, third joint broader, bilobed; claws
small, sim]»le, not divergent.

1. P. maculatus n. sp.

Blackish brown, densely clothed with brownish gra}^ scales, head and
middle of prothorax darker; the latter with a few white hairs near the
base. Elytra with a large, dark spot extending from the base to the middle,
and from the suture to the third stria; this spot is cniarginate on the sides,
and rounded behind; at one-fourth from the tip is a transvers(; undulated
dark line extending from the fourth stria to the suture; the space between
this line and the si)ot is clothed with nearly white scales; the stria' are ob-
scured I)y the dense covering of scales. Scutellum covered with i)ale scales.
Antenna' nearly black. Length 2 mm.; .08 inch.

California : two specimens collected at San Diego, by Mr. Crotch. This

In this tribe the funicle of the antenme has but five joints; tlie club is
eitlier articulated or annulated. Tl»e front coxte are very large and ])romi-
nent, contiguous in some of the genera, separate in others; tlie claws are
simple, approximate, free in Miarus, but connate in the other genera.

Tribe XIII. OEREl.oimxi.

A tribe whicli contains a few small species of oblong elongate form,
glabrous, and fetibly punctured, with the hind angles of the prothorax rect-
angular and better detined than usual. The beak is slender, long, cylin-
drical, and is usually projected forwards; it can, at most, be bent perpendicu-
larly downwards in rejOTSc; the antennal grooves descend oblif|ucly to the
lower edge of the eyes, which are moderate in size, nearly rovind, coarsely
granulated and distant from the prothorax. The antenna', inserted one-fourth
from the tip, are slender, the scape reaches the eyes; the fvmicle is 7-
jointed; first joint stouter, and as long as the two following united; the second
and the succeeding ones become slightly broader, rather closely connected
and merge into the club, which is pubescent, elongate, pointed, and strongly
annulated. The prothorax is quadrate for the greater part, then suddenly nar-
rowed to the tip, which is constricted; near the tip there is a short, acute
oblique lateral ridge representing a part of what is the lateral margin of the
pronotum in other Coleoptera. The prosternum is very long in front of the
coxic, which are nearly contiguous in our species, though distinctly sepa-
rated in the foreign genera; it is not emarginate in front, and the prosternal
sutures are o])literated. The elytra are scarcely wider than the prothorax,
parallel on the sides, conjointly rounded behind, so as to cover the pygid-
ium; the surface is punctulatc, and the striic are obsolete. The middle
coxie are moderately separated; the side pieces are diagonally divided, and
the epimera attain widely the base of the prothorax beneath, though they
do not intervene between the elytra and the pronotum. Metasternum mod-
erately long, side pieces narrow, widei in front. First, second, and tifth
ventral segments long; third and fourth united about equal to each of them;
surface rather fiat, sutures fine and wel' > 'j -cssed, nearly straight; second
suture slightly curved at the sides; in viic f j , the anal segment is slightly
visible at the tip of the fifth ventral. Legs rather stout, thighs compressed

This tribe is composed of a sintrle f^enus Jj(Pmof(treuii, of which one
species occuis in our Southern Stales. It is easily known by the exposed
pygidiuni; llie larije, prominent and distant fnmt oo,xiu, and the breast not
channeled. The side iiieces of th(? niesothorax are very transverse, and in-
tervene somewhat between the prolborax and elytra; the epistenia of the
metathonix are wide, and the epiniera are visible behind. The ventral su-
tures are stniiuht; first and second setrmenls ecpial, lonj;er than the third
and fourth. The lej;s are stout and short, iuul the tiliia' art' strongly iiooked
at tij); tlie tarsi are dilated, and the last jointis very slender, with two very
small, simple claws.

The beak is short, stout and cylindrical; the antennal jjjrooves extend to
the lower margin of the (.'yes, which are oval and transverse. The antennic
are inserted about the middle, and are scarcely geniculaled; the funicle
consists of seven joint and merges gradually into the oval, aniuiliited,
pubescent club. There is nothing jjcctdiar in the mouth; the gular jiedun-
clc is long, the tncntum small, and Hit; palpi short and small; the mandi-
bles are curved, and of the usual form.

The allinities of this tribe seem to be in the direction of Barini.

in common with several otb.er tribes, the beak is received upon the
sternum, and lies in repose in a pectoral groove, this tribe dilTers from
Zygopiiii'in. tlie smaller size, and different position of the eyes, wliich arc
more or less covered by the prothoracic lobes; and from Veutorhynchini by
the pygidium being entirely covered.

The pectoral groove varies in length according to the group; the front
cosifi are contiguous in many species of Conolrachelus, and other genera
of the group Ithypori. The side pieces of the mesothorax are obliquely di-
vided, and the epimera attain largely the base of the prothorax on the
under surface, witliout intervening between the pronotum and the elytra.
The nietasternunl is either long or Li.ort; the aide pieces narrow, and di-
lated in front. The vp'-.iral segments vary in length; the first suture is
straight or sinuate, deep, or obliterated; the second and third are some-
vhet angulated at the sides. The tibiie are armed with a strong hook at
the tip, and the articular surface is oblique; the claws are simple, oi
toothed.

But three groups are represented in our fa- na, of which the second is es-
tablished upon a new genus.

Pectoral groove coniined to the prosternnm, open behind :

Beak long, tarsi dilated Ithypori.

Beak short, tarsi narrow Ac»inpti.

Pectoral groove extending to the mesosternum, sharply

limited behind Cryptorbynchl.

Group I. ItbyporK

In this group the pectoral groove is confined to the prosternum, and is
not closed behind, the mesosternum is sometimes flat, sometimes suddenly
declivous. The eyes are coarsely granulated, partly covered in rejiose by
the protlioracic lobes, which arc sometimes very well developed, but in other
genera are broad and not prominent.

Th<! prothorax is, in most species, comparative!)' smaller than in the other
groups, and usually very coarsely sc\dptured. Tiie elytra tire wider than
the proihorax, with prominent humeri, the outer stria is usuallv abbre-
viated, and there is a tondiMicy to an epipleural fold. The thiglis are
toothed in our genera; the liliiic slender, hooked at the tip; the claws
usually toothed, though sometinu's simple, or even connate at the base.

The front coxte are sometimes contiguous, a character not observed in the
other g'.oups of this tribe.

This g( mis contains some of the most formichihlc enemies of our culti-
vated fruity, especially the stone fruits, such as tlie plum, apricot, itc.

They are easily recognized hy the cliaracters given above, to whicli maj'
he added t!»e following, which serve t j distinguish this from some foreign
genera; the antennal grooves are not confluent behind, and the hind thighs
are not pedunculated. ,

A sinsxuliir thougii harmless error has been committed by Schonherr and
Ilia colJaliorators in describing the antenuic of most of the species as "longe
pone medium rostri sita-." Geometrically this is correct, as the rostrui '
when not used in feeding, or in its equally legitimate occupation as ovipos-
itor, is inllexed upon the breast, and directed backwards; its tip is there-
fore in that position the pos'.'U'iwr extremity. ^lorpliologically, however,
the beak being an extension of the longitudinal axis of tiie body, the tip is
the anterior extremity; the word pone in the description should therefore
liave been ultra. The insertion of the antenufc behind the middle of the
beak probably does not occur in this tribe, or group, though in some of the
long beaked species of this genus (Nos. 11-13,) they attain nearly that po-
sition.

The species indicate the following divisions :

Claws divergent, toothed 2

" approximate, deft, (as in Anthonoiniin) , . 3.

2. Prothorax not sulcate, usually carinate 1,

(A. J^lytnxl costic intermixed; thighs bidentate :

Prothorax broadly sulcate, with two cn^sts in front II.

3. Pubisccnce i)ro8trate, fine III.

" mixed with stout, erect bristles IV.

As these ilivisions reciuire fuller definitions, the synoptic table of the
species will be found under each.

Division I— A. Sp. 1-9.

Tlie s]ief ies of this division an; related to C. nenuphir, and agree with
it in liavinii- the costie of Mie third and fifth interspaces of tin; elytra more
or less inl(rru])ted in two places. Tiie prothorax is not sulcate, but .isually
distinctly carinate, and strongly constricted near the tip; the thiglis are bi-
dentate. Tlicfie characters, except .he last, are evanescent in T. niroKUt,
which shows a passage to Division II, and appean closely allied lo C.

The pulu'scencc is short, line and appressed; it forms a mnn- or less com-
plex pattern of slender pale lines each side of the prothorax, and a broad
hand behind the middle of the elytra. In well preserved specimens the
color auil ili-trilnition of tin' pubescciu-p afford o:isy cliaracters for the recog
nition of the species; hut otiierwise, they arc closely allied, and reciuirc
care in their separation.

Middle States, on walnut. This species is closely allied to the i)luni
weevil, 0. nenuphar, and has been confounded with it uiUll the present
time. It Is, however, much larger, the beak is longer, more slender, and
less curved; the prothorax is broader and more rounded on the sides, the
crest of the fifth elytral Interspace is longer, almost as large as that of the
third, and overlaps It far more than half its length, and finally the pubes-
cence is of a nearly uniform color, so that the band of the elytra is not
variegated with white. The ventral segments are much less densely ))unc-
tured. It is mentioned as a phytophaglc species by Mr. B. D. Walsh, Illinois
State Report, 1808, p. 05.

2. C. albicinctus, n. sp.

Found over the Atlantic slope, wherever the plum is cultivated or native.
It attacks also other stone fruit, and is said to infest apples, pears and
quinces (Harris loc. cit). Furtlierol)scrvations on this point are desinible, as
it is very unlikely that such different plants are attacked by the same species.
The crests of the elytra are more abrupt, and the posterior ones more promi
nent than in the two preceding; the second elevation of the fifth interspace in
front of the middle is conspicuously smaller than that of the third inter-
space, and does not overlap it as much as in C. juglandis. Tlie elytral l)and
is composed of yellow and white hair; there is a conspicuous white lino at
the base of the third interspace. The thorax is longer and less rounded on
the sides, than in the two preceding. The beak is stout, curved, and
strongly striate and punctured; the ventral segments coarsely and densely
punctured; fifth with two setigerous tubercles; I liave many specimens
before me, which show no variation worthy of note.

An excellent memoir on this pernicious insect by the late B. D. Walsh
will be found in the Practical Entomologist, ii, 75; and some additional re-
marks in the First Annual Keportoflhe State Entomologist of Illinois, 18(>8,

Kansas; one specimen, Mr. Popinie. A large species of nearly black
color, clothed nearly uniformly with short, dark gray pubescence. Tlic
beak is long, slightly curved, strongly striate and punctured. The protho-
rax is densely rugosely punctured, with a small miH'ian callus, and some
indistinct tubercles; each side is a vague curved line of pubescence; the
sides are much rounded, and strongly constricted in front. The elytra are
striate with distant quadrate punctures, the alternate inl<?rspaces are mod-

Of the same form, size and color, as C. seniculun, but the beak is longer
and less ctu'ved; the prothorax is narrower, feebly carinate, and faintl^' tu-
berc\date; the lines of pubescence arc narrow, curved, and do not meet at
the front margin. Tlie carinse of the elytra are (juite similar, except that
the second one (that of the fifth interspace) is not interrupted behind at the
transverse band; the pubescence is more yellow, and less mixed with gray.
The teeth of the thighs are small, acute, and nearly etiual. The ventral
segments are more coarsely punctured than in C. affinis, and the first is not
less so than the others.

Colorado, abundant. This species reseml)les somewhat in appearance the
Texan and Mexican C. leucop/urtm, but is not otherwise allied to it.

Division I— B. Sp. 10-18.

The species of this division differ from the preceding, chiefly by the al-
ternate interspaces of the elytra bein'i; elevated, and not interrupted into
short, abrupt crests; the inner one (of luc third interspace) is in <nery case
entire. In other respects they resemble those of the i)receding division in
several important characters; the prothorax is more or less carinate, not
grooved; the surface is finely pubescent, with, at most, lines of very sliort
bristles on the elytra. On the other hand, the thighs are armed with a
single, usually acute tooth, without a trace of the second tooth or denticle.

New York, Georgia, Illinois. The form is broader and more squat than

in any other of our species, and it is easily distinguished by the Inimeri
being obliquely truncate, with the outer angle dentiform; this appearance
is produced by a sliort carina between the third and fourth elevated ridge
of the elytra, which meets the fourth ridge at an acute angle. The beak is
punctured and very deeply striate; head densely punctured; protliorax
carinate, elevated at the middle, broadly transversely impressed in front,
densely and finely cinereous pubescent, with an indistinct pattern of paler
pubescence each side, meeting in front of the middle. The elytra are
clothed with dirt-colored, slightly mottled, fine pubescence, with rows of
short, whitish setie; the third, fifth, seventh and ninth interspaces are
strongly carinate, leaving broad furrows, each marked with two rows of
quadrate punctures. The body beneath is tliinly clothed with yellowish
pubescence, sparsely punctured and cribrate; the third and fourth ventral
segments still more sparsely, and the fifth rather densely punctured. Thighs
armed with a large, not very acute tooth. The middle coxte are more
widely separated than in tlie other species. Length 5 mm.; .20 incli.

The beak of the female is a little longer and less deeply striate than in the
male; the last ventral segment in both sexes is foveateeach side, and feebly
impressed at the middle near the tip; but these impressions are broader in
the female.

Kansas, Mr. E. A. Popinoe, one specimen. The rows of punctures of the
elytra, from tlie absence of pubescence, appear black; the white dots oc-
cupy the distance between them, and contrast elegantly with the yellow
pubescence of the main surface. The white lines of the prothorax are nar-
row, and not very conspicuous; they converge but scarcely meet at the
front, and are sliglitly curved; the middle carina is also clothed beliind with
white hair; the scutellum and a small spot at the base of the third inter-
space of the elytra are also white.

Melsheimer Catalogue; no description was ever published by Say, and the
citation from the Journal of the Academy of Natural Sciences of I'iiiladel-

by the shorter and strongly striate beak, the dillerent position of the antcnnie ;
by the coarser punctuation of the jirot hom.v, which is less suddenly narrowed

white pubescence; by the elytra having tlie humeri, and sides niore rounded;
and linally i)y all the thighs being strongly though not acutely toothed.
Tlie under surface is very coarsely punctured, and the last ventral segment
has a broad, rounded impression. The mcsosternum is protuberant and per-
pendicular in front, as in the species of Division K, and in the three prece-
ding species. In some specimens the elytnil interspaces are eciually, finely
carinate; in others the alternate carin:c are obsolete.

RHYSSEMATUS Sch.

Concerning this genus I have little to add to the excellent synoptic table
and remarks published by Dr. Horn, (Proc. Am. Phil. Soc. 1873, 463)
except that the ditlerences between it and Ghalcodermus as stated by La-
cordaire are somewhat illusive; the corbels of the hind tibiie seem in some
specimens of 11. litutiticollU to be (luite distinct. On the other hand, there
is a great ditference in the form of the claws, which in Rhy»iiematu» are
cleft as in AiUhoiwmiiH, but in ChnlcodermuH are approximate and connate
at base, almost as in iSmieronyx, &c. There is also an important difference
in the two outer striic of the elytra, which are separated by a costa in the
first, just as in ConolracMuH, but in the latter the outer strife consists of
only a few large punctures extending one-third the length from the base,
and the interspace is flat.

In view of the importance of these characters it becomes necessary to
place C'halcodermuH pruinosia Boh., (Sch. Cure, viii, 2nd, 13) in this genus;
from the other si)e(;ies it is easily distinguished by the less rugose punctua-
tion of the prothorax.

OHALCODERMUS Sch.

The remarks of Dr. Horn upon the three species of this genus which re-
main after removing C. pruinosus leave nothing to be added.

Group n. Acampti.

As Qunptorhinus diflera from the Cryptorhynchi by the pectoral groove
being confined to the i)rosternum, though distinctly limited behind, so is
the singular insect which constitutes this group similarly' separated from
the Ilhypori, by the shorter beak resting upon the front coxiu. The body
is elongate, as in Camptorhinns, and the tibiie are stout, sinuate on the
inner side, and strongly hooked at th(! tip. The other characters are pecu-
liar, the tarsi are not dilated nor spongy beneath, and the clul) of the an-
tenna' is pubescent and sensitive only near the tip.

These characters indicate relationships in various directions, such as the
Byi'nopidir, and Gosiaonidm, but the insect preserves unchanged all the es-
sential characters of the Cryptorhynch type of Curculionidm.

AOAMPTUS n. g.

A very singular species of elongate form, clothed with dirt-colored hair,
and short, ere(;t bristles represents this genus.

The beak is short and stout, as long as the head, and expanding grad-

begin al)out one-third from the end, and descend obliipiely to the eyes,
which are small, lateral, and not prominent. Aniennie with the scape ex-
tending to the front margin of the eyes, clavate; funiculus not longer than

South Carolina to Texas, not uncommon. Judging from a MS. drawing

Group in. i'ryptorhynchl.

In this group the pectoral groove is distinctly limited behind. The other
characters are variable, though the front coxie are never contiguous as in
some Ithypnri; a slight api>eanince of an epii)leunil fold exists in many
species. Tlu! claws are toothed in Phyrdenas, but 8imj)le, and generally
small in the other genera.

The genera in o'.ir fauna are not numerous, but present several categories
indicating sub-groups, which it is iuineees.sary to define at present, as their
number would be increased liy a careful study of exotic forms. Mirrom(istn$
might be placed witheipial propriety in llhypori, iwar Art/iroslc.nns, but for

ACALLES Sch.

The very short metastcrnum, with indistinct episterna, the oval eiytra
with rounded sides, and the small tarsal claws will enable the species of
this genus to be easily recognized. The niesosternum is usually deeply
excavated for about one-lialf its length, so that the pectoral groove ends
almut tlie anterior limit of tlie middle coxie; liut this is not the case williyl.
7iuchali.s and pectoralix; the hind part of tiie niesosternum is i)rotubcrant,
80 as to maivc an obtuse angle with the metastcrnum. The distance from
the middle to t'lc hind cox;e is not greater tiian from the middle to tlie front
pair; the mesosternum at the side appears longer than the metastcrnum, a
very unusual character in Colcoptera. Tlie last two si)ecies described below
are anomalous, ami wlicn studii'd in connection with the foreign si)ecics,
will i)rotiably be considered as constituting new genera; in A. nuehalis
the nietallioracic side pieces are as distinct as in CryjUorhynchuH; \n A.

lire so large that the interspaces lieeome very narrow. I am disposed to be-
lieve that this appearance is ow iiig to jiartial abrasion of the scales. If,
however, with a larger series of specimens, il should be found to be really
distinct, the name A. ni'dhrosm Motsch. will be retained for il.

tills as the {' of the precedin;r s|M'cies, if the liristles of the elytra were not
so much longer. The form of the tdylru is ([uite ditlerent from any other
Acdlltt^ known to me, and resembles that seen in certain small (Jri/ptorhi/n-
chi. The longitudinal distance between the middle and hind cox.e is also
grotiter than in the other AcdUeii, and fully as great us in C. iniihiUmimux ;
but tlie metathoracic episterna are not visible, while in the insect last named
they are narrow, and very ajijiarent.

12. A. nuchalis, n. sp.

Very robust, clothed with brown scales, dark and paler intermixed. Beak
strongly punctured and sulcate, finely carinate, occiput clothed with pale
scales. Prothorax n(!arly twice as wide as long, rounded on the siiles,
scarcely wider at the middle, then rapidly narrowed to the tii>, but not con
strlcted; coarstdy and densely punctured, witli three very indistinct jmiIc
brown lines; a slight trace of a narrow median smooth line. Elytra ovate,
truncate at l)ase. n\uch rounded on the sides, obliquely narrowed behind;
basal angles obtuse, not prominent; striie composed of large, <piadrat«! pun(>

TYLODERMA Say. (IHJJl.)
AnakiH Sch. (18!{7.)

In this genus the licidc is rather short and stout, and the mcsosternum.
while very prominent, and forming a sharp (ulge which limits the pectoral
groove, is very feebly emarginate, resembling in this rebi)ecl AenUes pectc-
rulin. From .•l(V(//<'.'* it ditlers evidently, besides many otlu.-r characters, by
the more elongate form; the very distinct poslocular lobes, the prothorax
pronjinent and rounded in front; the hmger metasternum, with distinct,
though narrow side iiieces. P''rom ('ri/itlnrhi/iu'/iiiniX is distingtiishcd by the
form of body, the feebly emarginate mcsosternum, and the (l-jointed funic
ulus, as well as by the stouter beak, w ith more suddenly declivous anten
nal grooves. The first ventral suture is nearly obliterated.

The species fall naturally into two divisions already indicated liy Dr.
Horn, Froc. Am. Ent. Soc. 187:J, 407; the first contains the type of Tj/l'.-
deniKi, the ,-rcontl that of Aiiiilcix; I hiwc, therefore, restored the former
name to the conjoined genus.

Division I.

In the lirsl division the color is not metallic; the i)ultcscence is in distinct
spots, and sometimes scaly; the abdomen is coarsely punctured, and the
punctures of the elytra are large. These species resemble in appearance
Mwm<irle», but dilfer very greatly in structural characters.

I have nothing to add to the character-; of the four species of this group,
as given by Dr. Horn, but to say that 7'. foveolutuiu varies greatly in size,
some sjiecinunislicing no larger than 7'. rnricgdhun, from which it is at once
distinguished by the fovcate rather than punctate prothorax.

Southern and Wcsic in Stales. So far as the meagre description given
by Say goes, this species ;igrees well with his ('. i>hli(/ini.ii, but as Boheman
■md Say agret- in slating that that name belongs to the species called by the
former C. umbvotu*, I do not feel a! liberty to apply it to the present one,
for which r have adopte(] the Caialogui' name of Dejean. If our fauna had
mo e representatives of this genus, I would sejiarate this as a distinct divis-
ion, dirtering from the preceding, not only by the tibia- and stouter beak,
but ly tin- ninth elytral irierspace l)eing rot elevated, ami by the post
ocular prothoracic lobes being more prominent.

Division A — a**.

The single spe( ii-s n-presenting this division in our fauna is of ratht-r
large size, more elongate, and less ('i))io(nii'hclii!<\\ki' than the sjiecit-s of
llu! prec-eding division, from which it diflers chietlyby the tiiighs being
deeply sinuate beneath near the outer i-nd, and by the two denticles beini-
near together. The beak is stouter than in ('. fiiiriir/iiiH, but hardly more
s > than in C. fiiHCtitus, girinate and striate at linse; the antenme are inserted
about two tit^hs from the end; tin- funicle is slemler; second Joint as lonir as
tlie first, the others gradually sjiorter; clul) not percei)tibly annulated. I'm
thora.v rounded on the sides, strongly narrowed in front, and feebly c(»u-
siricted, postocular lobes not very distinct; basc-squan-ly trum-ate each side,
prolongeil into a distinct angle at tin- sculellum. Elytra om- third wider at
huse tlinn tiie protlnnax, m-arly pari-.llel on the sides, then narrowed to tlie

eh-vuted. The ventral sesrments are very eoarseiy piuu-tured, and tiie

BAROPSIS n.g.

The single species for which I propose; this generic name, agrees with
the two preceding genera in most characters, but ditfers essentially in the
first ventral suture being more distinctly sinuate, and nearly obliterated
at the middle, and the sei'ond ventral segment as long as the two follow
ing united. The licak is nearly us stout as in Tylodenmi, and the eyes
are approximate above; the funicle of the antenme is slender, 7 jointed, the
second joint as long as the first; the following are shorter, but not nnn'h
thickened; club small, oval-acuminate, annulated. Legs not very stout,
thighs feebly clavate, armed with a small acute tooth: tibia' moderately c(»m-
pressed, not as wide as in the two preceding genera, not toothed, ternunal
liook small; there is a fringe of hair on the outer margin towards the tip.
as in C'alosternns.

Tile I'orm of these insects is (|uitc peculiar; the body is elongate, sub-
riiomlioidai, the liist and second ventral segnients long, tlie remaining ones
short, rarely horizontal, as in the preceding genera, but forming an
obli(piely ascending surtiice. The pygidium is loncealed by the elytra in
our species, lail is visible in some foreign genera, The eyes are large, and
not concealed, even when the head is detlexed; they are closely approxi-
mati- on the front, but widely distant beneath and linely granulated. The
lieak is long ;ind slender, only slightly curved, and is received in a deep
pro>ternal canal, which in some species does not extend upon the meso-
sternum, so that 'he end of the beak is free, as in ('DiiolriirfiatuH. evtMi
when, as in others, the mesosicrnum is cxiavali'd, the canal is open and
not sharply limited liehind. Legs slender, front coxii' elongated, and pro-

OOPTURUS Sch.

The species belonging to our fauna are small and elongate, with the
elytra only a little wider than the prothora.x. They ditier from the typical
species of tropical America by the femora being not armed with a tooth.
We have seen already in many genera that this character is quite unim-
portant, and I consider it unworthy of even suiigeneric distinction.

Our si)ecies nuiy be thus tabulated:

sprinkled with paler, with two large basal spots of dirty white. Elytra
with deep punctured stria?, clothed with yellow and gray scales, with a
curved band, extending from the humeri to behind the middle, then curv
ing forwards and meeting the suture at the middle, thus forming on each
an oblique lunule of dark brown. Beneath densely clothed with large,
yellowish and grayish scales, legs slightly speckled with dark; thighs as in
the other species, unarmed. Length 2..5 mm. ; .10 inch.

171, pi. 11, fig. 8.

Easily knov/n by the small size and different style of coloration, which is
well represented in the figure given by my father, as above cited.

The beak, antennae, legs and elytra are reddish brown, the latter with
deep stria', and lines of white narrow scales, forming a broad basal band,
an oblique band behind the middle, and a narrow apical margin; the suture
is also white, but interrupted about the middle. Beneath and legs rather
thinly clothed with narrow white scales. The head and prothorax are
darker than the elytra, the latter is deeply punctured, with a lateral vitta
and a small ante-scutellar spot of white scales. The eyes are very large,
the front extremely narrow. Length 2 mm. ; .08 inch.

Southern States. Differs from all the preceding by the second joint of
the funicle of the antennte not longer then the third.

ACOPTUS n. g.

This genus differs from Uopturus by the ventral surface being nearly
horizontal, the segments much less unequal, and the sutures nearly straight,
as in Zygops. It is essentially difl'erent from that genus I)y only the first
joint of the funicle of tlie antenme being elongated, and b> the pygidium
being covered by the elytra. The mesosternum is long, flat, and slightly
declivous.

The second, third and fourth ventral segments are nearly equal, and the
fiflh is slightly longer, and broadly impressed in the specimen examined.

1. A. suturalis, n. sp.

Elongate, subcylindrical, black, sprinkled with small whitish scales,
forming two very indefinite bands upcm the elytra. Beak as hmg as the
prothorax, cyliinlrical, curved, punctured, slightly carinate behind, without
scales, except at the base; eyes very large, fnrnt extremely narrow, linear;
liead clothed with scales. Prothorax wider than long, slightly rounded on
the sides, narrowed in front, where it is broadly constricted; densely punc-
tured; dorsal line elevated, readiing neither base nor tip. Elytra a little
wider than the prothorax, impressed near the base; strire deep, interspaces
flat, densely punctured; scales scattered, more condensed in two transverse
bands, in front and behind the middle; scutellum and sutural line as far as

distinctly; antennse black, rather stout, first joint only of funicle elongated.
Length 3.8 mm. ; .15 inch.

New York; several specimens in Mr. Ulke's collection, of which he has
kindly given me one.

Tribe XVII. tavhygoikini.

This tribe contains a few small species, which in form and characters are
among the strangest insects of the family. The body is broadly ovate, nitlier
depressed above, and ornamented with tufts of hair; the prothorax is com-
paratively small, much narrowed in front. The head is small, the eyes
large, and the front very narrow, as in Zygopini; the beak is rather shorl
and stout, as in certain Geutorliynchini, and refracted upon the prosternum.
but the antenna? are straight, inserted near the base of the beak, not genicu-
late, and the first joint (scape), is no longer than the second; this is l()ll(nved
by five short joints, gradually increasing in width; the club is elongate-oval,
distinctly annulated. The front coxtc are sub-conical, prominent and widely
separated, so as to leave a space in which the ))eak rests when retracted.
The middle coxae are about three times more separated than the front coxa',
and the mesosternum is very short, transver.se, and perpendicul".i to I lie
general surface of the metasternuni, which is still wider. The side p'eces
of the mesosternum are large and distinct, those of the metaslernum are
narrow. The hind coxtc are oval, more widely separated than in any
other tribe known to me, and near the side margin of the elytra. The first
and second ventral segments are very large and connate; the third and
fourth very short; the fifth is nearly as long as the second, rounded behind.
The pygidium is exposed, and suddenly declivous at tip, presenting tlie ap-
pearance of an anal segment in both sexes. The front and middle legs are
slender and moderate in lengtli, the tibiw armed with a terminal hook;
tlie third joint of the tarsi is very widely dilated, the fourth joint as long a-;
the first, with divaricate and appendiculate ungues. The hind legs are
much longer and stouter, so as to clasp the leaves upon which the insect
rests.

The geographical distribution is remarkable; a few species of Tachygonu*
in America; one species of Binorhopala in Birmah. This fact, and tlie
extraordinary characters above detailed, indicate the preservation of an an-
cient form, which, although having the affinities I have mentioned, is
et^ually out of place in any position in a linear arrangement.

TAOHYG-ONUS Sch.

The characters of this genus are sufticiently exposed in the description
of the tribe. Our species are four, which may be thus distinguished:

A. Hind thighs armed with several long, acute spinules or teeth; hind til»
ise flattened and curved, feebly toothed on outer margin.

Maryland, southward to Texas; found on the leaves of young oaks, on
the under surface of which the insect sits, and falls to the ground when
approached, as observed by Zimmermann. The hind legs, though long
and powerful, are not saltatorial, as, indeed, Is evident from their form
and position; but being widely separated, and capable of lateral exten-
sion, they give to the insect a grasping power which is very great in
proportion to its small size. The curious movements in which, when
about to alight it turns itself Itack downwards, and seizes the leaf with
the elongated curved hind legs, are very well described by Zimmer-
mann, in the passage above cited.

are rather serrulate than toothed, the hind Xxh'vx arc straight, not Hat-

fused, and the white spot is very small.

3. T. tardipes, n. sp.

Pale brown, head, middle of prothorax, body beneath, hind legs in part,
scutellum, and four large spots on the elytra, blackish. Body above
thinly clothed with long, erect, gray hairs; prothorax not densely punc-
tured, with a tuft of fine, soft, whitisli hair at the basal angles. Elytra
with rows of deep subquadrate punctures, interspaces narrow convex;
with an angulated sutural spot in front of the middle, of soft, white hair,
and a few scattered small tufts of the same; each elytron with a large,
dusky spot on the humerus, and a smaller round one near the tip. Be-

Tril)e XVIII. CEVTOKHYXC'HINI.

This numerous tribe C(msists of small species of broad f(;rm, wit li the
beak and pector.il groove varying according to genus. They are distin
gulshed from all the preceding tribes with distant front coxa?, bj' the
pygidium being perpendicularly detlexed, and marked with a deep excava
tion (Mononychus), or with a continuation of the acute lateral margin of
the ventral segments, against which the ai)ical margin of the elytra rests.
In the latter case, the upper part of the dorsal segment is finely carinate;
in both cases, the anal segment of the rj' extends in front of the excavation
or transverse line. In all the genera the coriaceous sutural margin of the
left elytnm is much wider than in any genera of the C'ryptorhynchoid
series, including Zygopini.

The antenna; are geniculate as usual, inserted about the middle (jf the
beak; the funicle is 6-7-jointed, and the club oval-pointed, pubescent and
annulated. The side pieces of the me.sosiernum are usually visible from
above.

They may be divided into four groups, the first of which indicates more
properly a sub-tribe.

A. Pygidium without transverse line for reception of tip

of elytra; pectoral groove extending upon the

metasternum Monoiiycbi.

B. Pygidium with line for reception of tip of elytra,

and carinate in front of the line;
Pectoral groove, extending behind the prosternum. . t'cpiiodes.

Pectoral groove anterior, sometimes effaced.

Beak long and slender C'cntorhynohl.

Beak stout, usuallj' short Phy tobii

Group I. Mononychl.

A single genus constitutes this tribe. The species are of l)road form, and
larger than any others in the tribe, and are easily distinguished b\' tlic pygid
ium not being carinate in front, and witli no transverse line for the reception
of the tip of the elytra; the declivous exposed portion is, however, gibl)ous
at the upper part, surrounded with an impression, distinctly maigined in
the male; in the female there is a small, very deep excav.ition, surrounded

liy a thickened margin. The eyes are partially covered when the head is
(k'tlexed, and the beak, which is long and cylindrical, rests in a deep
groove extending through the pro- and mesosternum, into the metaster-
mim, where it is sharply limited. The side pieces of the raeso- and meta-
sternnm arc very large. The ventral sutures are curved at t he-
sides; the first segment is as long as the metasternum, the second is shorter,
third and fourth together equal to the second; fifth nearly as long as the
first, truncate and impressed in the male. Legs slender, thighs slightly
clubbed, tibiae obliquely fringed at the tip, terminal hook very small at the
inner angle. Tarsi with the third joint very broad, bilobed; fourth joint
small, with a single claw.

MONONYOHUS Geriii.

The genus is sufficiently defined by the characters of the group. One
species occurs in our fauna; otherwise it is represented by six species in
Europe, Northern Asia, and one in the Canary Islands.

Canada to Georgia, on Iris. Say states that it also occurs on the flowers
of Ceanothus americanui, and Verbascum thapsus in July.

Group II. Coellodes.

In the species of this group the eyes are partially covered by postocular
lobes, when the head is deflexed, and the pectoral groove extends into or
beyond the mesosternum, the l)eak is long and cylindrical. The side pieces
of the meso- and metasternum are large and wide. The ventral sutures
are curved, and the first is as deeply impressed as the others; the second
segment is shorter than the first; third and fourth still shorter, fifth nearly
as long as the first. The pygidium is perpendicularly deflexed, marked
with an elevated angulated line for the reception of the tips of the elytra,
in front f which it is carinated. The third joint of the tarsi is very broad
;ind bilobed, the fourth is as long as the first, with two claws, which are
deft, or toothed.

addition, tlic pectoral groove prolonged to the posterior niaririn of the
nietiisternum. Tlic funicle of the antenna? is slender, and conssists of

Middle, Southern and Western States. Easily known hy the hroad
form and dark color; the prothorax has four large tubercles, of which the
outer ones are acute; the dorsal canal is prolonged to the apical margin.
whicli is slightly omarginated thereby. The alternate interspaces of the
elytra are more elevated and somewhat uneven, as in certain Conotracheli.
Length 2.7 mm.; .11 inch.

CNEMOQONUS n. g.

The tibia' of one species are so different from those of the other Cixliodes.
that I am obliged to regard it as a separate genus. They are, namely,
mucli flattened and dilated externally, so as to form a large angle near the
knee. The outer apical angle of the front tibia; is prolonged in a toothed
process, as in Caliodes, and the other tibia; are obliquely truncate and
fringed externally. In other respects this genus agrees with Caliodes; the
pectoral groove is not prolonged into the metasternum, as in Craponius, nor
are the til)iie grooved externally for the reception of the tarsi. The thighs
are not toothed, and the claws are armed with a short tooth, not cleft, as in
deUodes.

Widely diffused in Europe, from Scandinavia to Austria. I have a spec
imen from Great Slave Lake, and one from British Columbia, which seem
to l)e the same. Apart from the generic characters above given, this spe
cies is easily known by the interspaces of the elj'tra, rough with small
acute tubercles ; near the base there is a small cruciform white spot,
formed by the junction of a short sutural line with a transverse one, which
<;xtends to the third stria. Length 3.2 mm. ; .125 inch.

OCELIODES Sch.

In this genus the tibise are slender, not flattened nor toothed on the outer
margin, but the front pair, in some si)ecies, are prolonged at the outer
apical angle into a short process, which is toothed on the lower edge. The
pectoral groove extends as far as, but not upon, the metasternum. The
claws are nearly cleft, the inner parts being almost contiguous, as in most
tipccies oi Anthonomus.

Group IIL Ceutorhynclil.

Tlie species of this group are small, and of the broad ovate form usual
in the tribe. They differ from the preceding group by the pectoral groove
not extending behind the front coxoe, and from the next group by the l)eak
l)eing long, slender, and curved ; usually about lialf the length of the
body. The eyes are small, not prominent, and are partially concealed in
repose by broad prothoracic lobes. The prosternum is suddenly and very
deeply emarginate in front, and the antecoxal ridges defining the pectoral
groove are acute and elevated in all our species.

The beak is stouter and more coarsely sculptured in (f, and the last ven-
tral segment is impressed.* The species in our fiiuna are not very numer-
ous, and all belong to Ceutorhynchus ; some European species with G-
jointed funicle have been separated under the name Ceutorhynchidius,
but I see nothing in our species sufHcient to warrant the adoption of such
a division.

* By an unfortunate error, Suffrlnn (p:nt. Zeltung, IS-l.j, lO'i) has stated that
the females have tlie ventral Impression. Thompson, however, (Skand. Col.
vii, passim), reports the sexual difference correctly.

Group IV. Phytobll.

The species of this group difler from the Ceutorhynehi only by the beak
being stout, and usually short, in one instance scarce!}' as long as the pro-
thorax. The prothoracic lobes are feeble or wanting, the eyes are some-
times partially covered in repose, sometimes entirely free. The pectoral
groove is sometimes well defined by anteco.\al ridges on the prosternuni,
but occasionally these are absent. The rirst genus exhibits a very singvilar
reversion towards the Bayous group, Mith ^ hich it might indeed be placed,
were it not that the pygidium is exposed, Uud similar in sculpture to tlmt
of the other members of the present tribe, and, also, that other characters
correspond with the position here assigned to it.

The genera are somewhat diflicult to define, in consequence of the im-
portant structural characters by wliich the species are distinguished. It
is probable that they will be increased in future, by those whose views
tend to the multiplication of genera, but for the present, I think that the
divisions liere adopted express both conveniently and naturally the aflini-
ties of tlie species known to me.

disc is feebly longitudinally impressed behind the middle, and the lateral
tubercles are small and indistinct. Elytra deeply striate, nearly twice as

with depressed greenish yellow scales ; the prothorax has two broad dark
stripes ; the elytra are more thinly clothed with scales, except the sutural
interspace, which is densely covered. The antenna' and legs are bright
yellow, with the knees duskj'. Length 2 mm. ; .08 inch.

PBLENOMUS Thomson.

The species of this genus are easily distinguished by the short stout beak,
which they have in common with Rhinoncus and C< dog aster, being com-
bined with prosternum somewhat emarginate in front, but without antc-
coxal ridges. The eyes are round, convex, without orbital ridges, and
are completely exposed in repose, on account of the entire absence of the
postocular lobes of the prothorax. The claws are simple and moderately
large. The funicle is G-jointed, with the first joint longer and stouter ; the
club is rather large, oval-pointed, annuhited and acuminate. There are
but three species in my collection :

A. Funicle slender, 2d and 3d joints distinctly longer.
Prothorax broadly sulcate, apical and posterior

tubercles strongly marked, acute 1. sulcicollia.

B. Funicle shorter and stouter, joints 2-H very little longer.

CCELOG ASTER Sch.

This genus is easily distinguished from both lihinoncus and Pelenoinuit
by the eyes being inserted under distinct, acute, superciliary ridges or or-
Iiits, and being jiartly covered in repose. There are also important ditt'er-
<'nces in the sternal pieces; the prosternum is still more deeply and sud-
denly eniarginate in front, so as to reach almost to the front coxae, which
also reach almost to the hind margin, and are more widely separated than
in either of tlie genera just named; the ridges in front of the coxtc limiting
the pectoral groove, are much stronger. The mesosternum is truncate be-
liind at the middle, and enters less into the formation of the middle coxal
cavities. The intercoxal process of the metasternum is therefore almost
square, and the middle coxse are more posterior than in the other genera.

Tlie beak and claws vary according to species; the funicle is 6-joinle(.l,
the fii-st joint being stouter, and the others slender ; second and third elon-
gate ; 4-() sliorter, equal, scarcely thicker, club elongate-oval, pubescent,
acute at tip.

Three species are known to me, of which the first is the type of the
genus.

nate in front, with distinct anteeoxal ridges.

The middle ooxse are normal in position, ^their cavities being formed
eqiially by the meso- and metasternum, whereby it diflfers notably from
Ccelof/aster; it also ditt'ers from that genus by the eyes, which are rounded
and convex, as in the other genera, and without any trace of superciliary

thorax is very coarsely punctured, feel)ly channeled, and the lateral tuber-
cles are not very distinct. Length 4 mm.; .10 inch. I do not know why

iribo thill the iii.artst approach to Calandrida and ros»o« iWd; is nuuU', in
form and general apijcarance, though the I'ainily characters arc (juitc dif-
ferent.

The following characters will enable them to be distinguished from the
other tribes iu which the front cox.e are separate.

Beak not received closelynipon the sternum, which however is some-
times broadl}' sulcatc in front of the anterior coxte; when this groove does
not exist, there are sometimes seen {Mnilarm) two short approximate
ridges, limited inwards by an impressed line, whicli may l)e regarded as
the last remnant of the pectoral groove. In other cases (Baria ittriutus)
even these lines disappear, and the merest trace of a concavity remains in
the apical constriction of the i)rothorax, which in all the species is not
emarginatc l)eneath, and is destitute of postocular lobes. In many others
even this slight concavity or flattening is wanting, and the apical part of
the prothorax is altogether cylindriail, al)ove and beneath. The meso-
and metasternum are closely united, and the suture between them is fre-
quently obliterated. The side-pieces of the nu'sothorax are so extended
outwards and upwards, that they intervene strongly lietween the base of
the prothorax and the elytra The sides of the latter, therefore, become
obliquely truncated, giving a form not ()l)served in any of the i)receding
tril)es. The other characters are soiuewhat variable. The i)ygidium is
sometimes exposed, s onetimes covered. Tlie claws are sim])le, and either
divergent, connate, or even (B<( •ilepton) single.

The genera in our fauna represent two groups:

Pygidium exjiosed, usually vertical; fifth ventral segment

in the latter case truncate or subemarginate Barldci*.

Pygidium oblique or horizt)nlai, not fully exposed; fifth

ventral segment rounded at tip Centrlnl.

Group I. BarldeM.

The separation between this group and the Centrini is not very dcflnite,
though characters such as the perpendicular pygidium, and the shorter and
stouter beak, seen in most of the species, do not occur in the last named
group. The main character to be relied on, in the absence of the easily
recognized habitus, is that the elytra are more broadlj- separately rouiuled
at tip, and the i>ygidium thus becomes more exposed.

AULOBARIS n. g.

I have separated as a distinct genus some specimens from the Atlantic
slope, which ditt'er from Burh jjroper by the more slender antennie; the
first joint is scarcely stouter than the second, and the latter is (juite as long
as the first; ihe remaining joints C;{-7) are gradually slightly wider and the
club is elongate-oval, uniforndy i)ubescent except at the base of the first
joint, and not large. The beak is longer than the [irothorax, cylindrical,
slightly compressed towards the base, and not very slender. The front
coxa' are rather widely distant, and the prosternum is deeply and broadly
sulcate in front.

The body is more convex than usual in Burin, though in this respect, the
species resemble Pxeudohoris farcfa. The under surface is coarsel}' punc-
tured, with a small white hair in each puncture.

These species represent group B of my synoptic table in Proc. Ac. Nat.

As I liav(! licre restricted this genus, it contains only tliose species in
whleli the club of the nntennie is Rninll, nearly round, with the fast joint
not sensilive, shininjr, and constituting more than one-half the mass. The
claws are separate, divergent, and of moderate size, and in some of the spe-
cies {Hparm, &c.) small. The beak is stout, usually short, and nuifli curved;
the frontal constriction rather deep; sometimes it is a little longer than
the prothorax. The fnmt coxa- are never very widely separated; the pro-
sternum is flat or broadh' sulcatc according to species. The pyiiidium is

culiarity, wliicli is extremely rare among Carculionidiv, and in I'-.wl among

Middle and Southern States. I have retained tliis name for a species
which is quite distinct from all others in our fauna. The well marked
structural characters which enable our species of Bdris to be easily si'jja-
rafed, were, however, not perceived by Say, nor by the collaborators of
Schonherr, and I am therefore doubtful if the jiresent nani!; should lu' prt-
served. As far as I can judge from the descrii)lions, this spec es is the one
intended by Hoheman, founded upon a typical si)ecimen from Florida scmt
by Say, and on others from Souih America. Hut I am very uncertain if it
l)e the one originally described by Say, and ((uite doubtful if that original
be the same with tlie one sub.sequently referred to (Cure. Vi), of which it
is said that the punctures of the elytral inerspaces "have a transxerse
rugulous appearance." In the original dv'scripion (J. Ac. iii, Hit), these
same punctures arc declared to l)c orbicular.

Head sparsely punc:ulate, beak finely punc'ured, frontal constriction
strong; pro'horax strongly but not dciusely pune ured, scarcely wider than
long, slightly narrowed from the base; for two-thirds the length, then more
suddenly rounded and narrowed to the tip, which is feebly impressed at 'he
sides. Elytra with deep striiP, in'erspaees fla', each with a row of very

anJ inore distant in the specimen from Oregon, than in those from Califor-
nia. The la'.ter being better preserved show fine but di.stinct whi e hairs
proceeding from each iiiters;itial jninc ure. The thoracic snuxnh dorsal
line is very distinct in the Caiifornian, but almost obsolete in tiie Oregon

constriction deep. Prothorax wider than long, feebly narr.iwcd fitun the
base for two-thirds the length, rounded on the sides, slightly const ric.ed
near the tip; very deeply and coarsely rugose, leaving narrow elevated
folds, nuich as in lihi/Hsematus; there are a few scattered yellow hair like
scales; bas(; scarcely sinuate. Elytra a little wider at base than the jjrotho-
rax, gradually narrowed behind, scarcely' separately, biM almost conjointly
rounded at tip; siriie deep, interspaces Hat, each with a row of small tlis-

tured, marked in front with two lines converging behind, and enclosing a
smooth triangular space. Club of antenna; small, oval rounded, pul)escent;
claws divergent. Length 4.2 mm.; .17 inch.

Middle and Southern States. The pygidium is less exposed than usual,
but is perpendicular, so that this species cannot be confounded with Cen-
trinus, in which it is nearly horizontal, or at most oblique.

PSEUDOBARIS n. g.

The species of this genus have the second joint of the funicle no longer
than the third, and the club not larger, oval, with the first joint i)ul)escent
and sensitive, and constituting less than one-half the mass; the claws arc
approximate and slightly connate at base. In these respects they agree
with Trichoburis, but ditier by the front coxie being very widely sepa-
rated, and by the absence of dense scaly or hairy vesliture, though there
are a few scattered scales on the elytra of each species. The prosternum is
broadly sulcate in front; the limits of the groove are less sharply defined as
in Aulohiiris.

silicate, thus showing a tendency towards Aulobarin, which it resembles in
appeiinince, fhougii the limits of the gnove are ill-defined. Tlie second
joint of the funicle is however no longer than the third. The basi' of the
third intersi)ace of the elytra has a small scaly spot, and there are also scat-
tered hair like .scales. The strite are deep, the piinclures of the interspaces
are transverse and rather confused. Length 4-5 mm.; .I()-.20 incli.

Southern Slates. The white scales are very sparse, and easily removed;
they are arranged singly upon the inlerspacL's, except at the base of the
third intei-space, where they form a small spot. The prosternum is broadly

3. P. angusta (Lee.), Pr. Ac. Xat. Se. Phil. 1H(;«, 303, (noridiiix).
This species, from the material now al my command seems scjiarable

from J', nii/rina only by its narrower form, the sides of the prolhonix nearly
parallel behind, and by the entire absence of smooth dorsal line of the pro-
thorax. Specimens from Texas' which are clearly referable to /'. nir/rina,
vary in the last mentioned character, the dorsal line being either distinct or
obsolete, so that onlj' the form of body remains to dis;inguish tluni apart.
Length 2.T-3.3 mm.; .11-.13 inch. Illinois to Kjinsas.

In one specimen a few scales remain, indicating a vestilure similar to the
prec 'ding. On re-examining the specimens I find my former observation
that the second joint of the funicle is longer than the third is incorrect.

4. P. pusilla (Lee), Pr. Ac. Nat. Se. Phil. 1808, 303, (Daridins).
New York, one specimen. Allied to P. nigrina, but more oval and less

elongate, wiih the punctures of the prothorax less coarse, and without
smoo h dorsal line; the sides are also more obli(iue. Head and beak sparsely
finely punctured; the latter as long as the prothorax, rather slender, very
slightly curved. Elytra with deep strite, and rather wide flat interspaces,
each with a row of fine but dislinct punctures; the specimen is rul)b d, but
a few white scales are visible at the base of the third interspace, wliieh in-
duce me to believe that in well jireserved spi'cimens they are scattered as in
the i)reeeding species. The prosternum is broadly and strongly suleate,

In well preserved specimens the surface is clothed with scattered, small
white scales, which are mori' dense at the sides of the prothorax, at the
base of the third interspace of the elytra, and the side pieces of the meso-
and n'etathorax, and at the sides of last three ventral segments. These
scales are iiowever easily abraded.

AMPELOGLYPTER n. g.

This genus contains species which depredate on the small steins of grape
vines and allied plants, producing excrescences. Two of them are readily
distinguished from the preceding genera by the smooth and shining surface
of the elytra, the interspaces of which are wide and not ininctured; the
stri:e are fine, the posterior callus prominent, and the surface undulated by
broad transverse iiupressi )ns. lu these respects tliey resemble Mddarus,
but diller by the shorter and stouter beak, the stouter antennie, and the
broadly excavated prosternum, which is not suddenly declivous between
the coxic. The front thighs are not toothed, and the claws are connate at
base .
The form is also quite dift'orent from Madarus; the elytra are a little
0 wider than the prothorax, as in B<(m.

are entircdy black; those from the South ami West have the protliorax red.
Although Moheman di'scrihed all the thijihs as toothed, I find that the mid-
dle and hind pairs are quite unarmed. The tooth of the front pair is rather

large, but obtuse.

Group II. <'eiitriHl.

The only characters I can give for the recognition of this group, as dis-
tinguished from Jiarides, are : the elytra conjointly rounded at tip, or
nearly so ; the pygidium thus becomes entirely covered, or oidy partly
exposed, and is nearly horizontal, oral most somewliat oblique, and never
vertical. The last ventral is consequently regularly rounded at tiii, never
truncate or emarginatc. In addition to these characters the ventral surface
of the abdomen is more convex, frequently ascends obli(|uely, as in Zi^t/o-
pini, but in a nnu'h less degree. The tibial hooks are less developed than
in Ihin'i* and its allies, and in many species are scarcely apparent. The
beak and antenna' are generally of more slemler form than in Jiitris, but
these characters are not without exceptions, as will he seen below.

CENTRINUS Sch.

After separating a certain number of .species, which seem to indicate
distinct and well dcfmed s^eiiera, there remains a tolerably numerous maas,
whicli, although not entirely homogeneous, consists of species liaving in
common tlie following characters. The study of f«)reign specic^s may per-
mit at a future time a farther subdivision, but the transition between the
extreme forms seems so gradual, that 1 am unwilling, wRh my present
knowledge, to indicate tlic manner in which tliis may be etfected.

The beak is long and slender, cylindrical, and usually curved, but some-
times nearly stiaight; th(> antenual groove commence about the middh?,
descend obliquely, and arc wider, deeper and couHuent behind. INIandi-
blcs small, tiattened, ])oiuted, prominent, and without teeth. Antemitu
rather slender, funifle 7 jointed, joints l-;5 varying in length, 'l-T coual
in length, not passing into the club, which is oval, somewhat poiiufi' pu-
bescent and annulatctl. Prothorax narrowed and nu)re or less consiricled
in front, without poslocular lobes; pri)steru\un long in front oi" ii.cc.Aa!,
which are ratluuMvidely .-('paraled; not cmMrginale in front, impressed or
not, according to species. Elytra sometimes elongate with parallel sides,
though usually narrowed from the huiMcri, .so as togi\e a rliomboidal form
of body; posterior callosity feeble, tilts usually conjointly rounded, somc-
thnes separately rouiuled, exp(<sing in the latter case a small part of the
pygidiuni, which is, howe\cr, horizontal, and not vertical, as in Burk antl
its allies. The middle and hind cox;e an; widely s(.'i)arated; metasternuui
r^ither short, with wide episterna in the rliomboidal species; h)nger, with
narrower cpisleriia in the elongate sp-'-cics; but in Ik. li cases distinctly
wider before and behiiul. ^'enlral surface ascending in some si)e(;ic3,
nearly horizontal in otlieii.;.lirst and second joints long(,'r tluui tliirtl and
fourth ; tifth sometimes longer, sometiuns not longer than IIk; fourth :
first suture subsinuate, the others strongly augulated at the sides.
Thighs unarmed, tibia? not striate on the outer side, very feebly mucronale
at till; tarsi with the third joint very broad. liilolK'd. last joint long, wi»
stout, divergent claws.

In the males of several sitecies the prostcrnuui just in front of the coxte is
armed with a slender process, which varies in length according to the in-
dividual, but not according to species.

An abundant species over tiie whole of the Atlantic district. Varies
consid: rably in size (8-4.7 mm.; .12-.18 inch), the smallest specimens
occurring in all parts of the country; also in form, some of the smaller
siieciiiiens from Texas being less robust, with the sides of the i)roth()rax
less rounded; also in vestiture, which is. sometimes denser and j'cllowish, and
sipiaiuosc upon the elytra, in specimens from Texas. The white scales of
the scuieilum are not vnifre(iuently removed by abrasion. Tlie antennie
are stonier than in the following species, and thesecond joint of the funicle
of the aiitenme is distinctly longer than the third; the prosternum is deeply
transversi'ly impressed, and is flattened behind tlie impression, but has no
trace of spines in either sex. The metasternal episterna are wide; the fifth
ventral is scarcely longer than the fourth. The anal segment is exposed in
the i\ and is slightly declivous. Of all tlie species in our fauna, this
makes the ne; rest approach to Baris.

Tribe XX. iioRtioPiKi.

The sub-family of genuine Ciirrnlioniihv fitly closes wilh a very anoma-
lous insect, which whih' having relations with several of the curlier tribes,
exhibits in adtlilion a character which is o:lu'r\vise se(>n in one of the sub-
families of the Gahindridtr. The eyes, namely, are very large, transverse,
and coarsely granulaU'd; they are widely separated above, b-ui nre nearly
contiguous lieneaih. It follows from this that the antennae in repose must
be received in front of the eyes, which therefore form as it were a collar be-
neath; and the antennal grooves, which are deep and obli(pie, a'.taining the
ej'cs near the upper end, are suddenly and acutely flexed iieneath, forming
a deep, transverse excavation in front of the eyes.

The beak is shorter than the prolhorax, stout, somewhat flaMcneil, a little
wider a: tip than base; the mandibles arc rather flattened, acme at tip,
toothed on the iuuer side. The gular peduncle is small and narrow, ciar-

HORMOPS n. g.

The single species representing this genus and tribe in our fauna, is a
small, incnnsi)icuous black insect, thinly clothed with rather coarse yellow
hair, and reminds one in general ai>i)earance of the Erirliine genus Prorat
(p. 102). The characters as above detailed are quite anomalous, and no
further generic description is at jiresent necessary. It is possible that it
may have relations wi;h some of tlu; anomalous genera placed by Mr. Wol-
laslon among the Coxnoiiiihr, but as I have had no opporlunily of studying
them in nature, I can but timidly suggest the propriety of comparing this
genus with those genera of Co.uonidif in which the eyes are dispo.ied to be-
come confluent beneath. The entire facies of this insect is so purt'ly Cur-
culionideous that (tlie se.vual characters being unknown), I would be un-
willing to place ii in any other family.

Subfamily V. BALANINIDJE.

The single genus which constitutes this subfamily has been lioretofore
arranged as a tribe, in the vicinity of Anthonomini. It differs, however, from
that tribe, as from all other Coleoptera, known to n»e by the movement of the
mandibles being vertical instead of horizontal;* the mandibles are short, pyr-
amidal and acute, and the condyle ison the upper side; the teeth seen in mcst
Curculionidtc are wanting; the inner edge is mori' convexly curved than the
outer, so that in the ordinary position, the jwints seem slightly divergent. In
general appearance, as well as by the extension of tlie mesothoracic epimera,
so as to give an oblique outline to the elytra near the base, this subfamily
seems to me to approach Ce>Urinu» more than Anthonomua ; the risult of
this obliquity is that the tenth elytral stria commences at the margin, oppo-
site the anterior end of the me;ath</racic episterna, as in all Burini.

The beak attjiins in length and attenuation the greatest development; in
the (f it is rarely shorter than the body; in the 9 it is frequently twice
the length, and is used to nmke the iwrforatiou into which the egg is sub-
seciuently introduced. The great thickness of the husks of the fruits
(chestnuts, walnut,^, hickory nuts, &c.), depredated on by these insects,
necessitates a very long perforating instrument to reach the kernel, upon
Avhich the larva feed?.

The mouth organs arc small, the gular peduncle very long and narrow.
Tlie antenniB are inserted a little before the middle (j^), or behind the
middle (9) of the beak, and are very long and slender; the funicle is
7-jointed; the first joint is either hmger or shorter than the second, and the
outer joints are gradually a little less elongated; club elongate oval, pointed,
annulated and pubescent. Eyes rather large, flat, nearly rounded, finely
granulated. Prothorax rather long in front of the coxir, which are contig-
uous; broadly emarginato in front, without postocular lobes; pronotum
rapidly narrowed in front, sides rounded, base slightly bisinuate. Scutel-
lum distinct. Elytra narrowed behind, tips separately rounded, pygidiunj
more or less exposed. Side jiii.'ces of nu'sothorax attaining widely the base
of the prothorax, and truncating the humeral outline of the elytra; meta-
tlioracic episterna narrow, dilated in front. First ventral segment longer
than the second, and closely united with it; the others an nearly eipial in
length. Middle coxie modi-rately distant, hind coxa; widely distant, not
attaining tlie clylral margin. I^egs long, thighs clavate and strongly
toothed in our species; tibiae slender; truncate at tip, not mucronate ;
tarsi dilated, claws divergent, to<»tlu'd.

developed to such an extent as to conceal the ligula and labial palpi. Of the
genera known to me Vylas is the only one in which the niaxllUe are ex-
posed l>y the nientum not filling coinjjletely the buccal cavity, though other
cases are mentioned by Lacordaire.

But what is most curious, is that while the mandibles of the 9 preserve
the pineer-form seen in many Curciilionidie, and the beak is slender, and
in some species extremely long, for the purpose of performing its function
as an accessory organ of generation,* in the rf the mandibles assume a flat,
curved, and pointed form, resembling those of ordinary Coleoptera. This
sexual character is exhibited even in those genera in wliich the beak of the
(^ is nearly as slender, and the moulh as small as in the 9-

Tiie explanation of this ditl'erence in the mandibular structure is afforded
by the interesting remarks of Mr. A. II. Wallace, concerning the wonder-
ful i)ugnacity of the (^ c? when in proximity to the 9- -^'i excellent ac-
count of the assistance given by the (/* to the 9 when siie is occupied in
boring the hole in which the egg is placed, is also given by C. V. lliley,f
from observations made by his correspondent W. R. Howard, of Forsyth,
Missouri,

These coml)ats, however, result in no injury to either of the parties en-
gaged; the dense chitinous covering allbrds a perfect protection; the
weaker male, overcome by exhaustion, eventually flees, and leaves to his
more vigorous victor the honorable task of guarding and assisting the fair
object of strife in her efforts to preserve the species.

The habits, therefore, of these insects, as well as their peculiarities of
structure, deserve a closer attention than has yet been given totliem.

The smooth eyes, tiie reticulations of which are seen only through the
transparent integument, and the form of the front tibiie, indicate a resem-
blance, though a remote one, to lihyitHodidir. such as might perhaps exist
among objects of quite difterent nature originating in the sau\e period of
time. The geographical distribution of the Brenthidie is al.so favorable to
the idea that they rei)resent a toleraljly ancient form of life.

The great extension of the longitudinal axis of the body exceeds in some
members of this family any proportion that occurs in other Coleoptera; and
it is singular to see that a character, which usually indicates feebleness of
development, is here associated witli densely chitinized integuments, and
great complication of donu^slic life.

The family divides itself naturally into two subfamilies, the characters
of which have been sufHciently exposed above.

Subfamily I. BRENTHID^: (genuini).

Of this family two genera belong in the faunal limits treated of in this
memoir, though one of them {Tirenthuii), is in a political sense extra limitul.
having occurred in Lower California.

Tliese two genera represent in the arrangement of Lacordaire separate
groups, but in the plan of subordination of characters herein adopted, they
seem to indicate what I have called tribes, which may be dislinguisluHl by
the sexual and other ditterences in the head, as well as by the form of the
prothorax.

Beak very dissimilar in the two sexes; antennie not very remote from
the eyes, rather slender, not compressed, nor clavate; prothorax convex,
not grooved AKRUE3iOUlxl.

Beak slender in both sexes; antennte far distant from
the eyes, somewhat thickened and stouter externally;
prothorax deeply grooved towards the base

Tribe I. ARKHK!«o»lxl.

The genus Eupsali'», represented in our fauna by a single species, differs
from ArrJienodes by the brilliant lustre of the surface, and by the bind part
of the head being less prominent; in view of the magnitude of the varia-
tions in the rf (f, which I have mentioned below, I have great doubt of
the generic value of these characters; neverlheless, my opinion can only
be tested by a careful study of foreign species, which would interrupt the
progress of the present memoir, and is, moreover, not essential for the elu-
cidation of our own fauna.

The distribution of Eupsalis, even as thus limited, is remarkable; one
species in North America, one species in Guinea, and one in Madagascar,
and perhaps one in Brazil. It is worthy of remark in this connt-ction, that
the genus Amorphoeephalus, the only Brenthide found in Europe, is also
represented in Australia.*

black, tlie red iind llie post oaks are mtintioncd us those which are known
to Ite attacked. By some curious inadvertence, Olivier in the Encyclopedio
Metiiodiiiue cites for this species No. 84, plate ii, f. i); a totally distinct spe-
cies, which in the text (v, 4ii!)) is named Ii. m litarU.

A description of this very well known insect is here unnecessary, hut a
notice of the variations wiiich I have observed in the head of the males
may be of inlc^rest.

The females vary In length from 6.5 to 14 mm.; .2.'i to .50 inch., from
the eyes to the tip of the elytra. The head is rather 8'ron;>;ly constricted
immediately behind the eyes, which are convex and prominent. Imme-
diately in front of each eye is a deep fovea; and in advance of them is a
deep frontal excavation; the ridges above the insertion of the antenna' are
prominent, and not angulated; the beak in front of the an'ennie is as hmg
as the joints 1-9 of the antennie, which are shorterand stouter than in the -^.

The males vary in length from 7.2 to 17 mm.; .28-.G7 inch, from the
eyes to the tip of the elytra. The head affects three ditt'ereut forms, which
seem to be independent of size :

1. The head is suddenly, but not strongly constricted behind the eyes,
with the lateral angles obtuse, but distinctly outlined; the ridges above the
antennic are very prominent, angulated behind, and separated from the
front by a deep impression; the frontal impression is large and deep, and
the median elevation in it is feeble; the beak in front of the antenme is
strongly dilated, much wider than long, wiih scattered elevated granules,
and with a well developed ridge each side, which is suddenly more elevated
at its posterior end; there are also two shallow impressions. The mandi-
bles are as long as the beak in front of the antennte; the cusp on the inner
side is distinct and the apex of the right mandible has three cusps, that of
the right but two. This form occurs in Michigan and Georgia.

2. The beak in front of the antennae is not transverse, but fully as wide
as long; the other characters as in (1). This form occurs in Kansas and
Texas.

3. The beak in front of the antenna; is nearly twice as long as wide, the
lateral ridges less developed, the granulations more numerous, the mandi-
bles comparatively shorter and stouter; the frontal impression more elon-
gated, with the median elevation more distinct; the ridges above the inser-
tion of the antenna; are less prominent, not angulated behind, and the head
is less suddenly constricted behind the eyes, with the angles so much
rounded as to be nearly effaced.

These characters are somewhat similar, as regards the development of
the supra-antcnnal ridges to those observed in Lucanidce, but in the varia-
tion of the length of the beak are rather anomalous. They indic^Ue, how-
ever, the propriety of recasting the classification of this family, and defining
the genera and species by the invariable characters of the female, rather
than by the perhaps individual modifications of the male.

The measurements given above show a slight average superiority of size
in the male, but not sufflcient to warrant any generalization in favor of

sexutil selection, produced by tlie bloodless coinlmts of faese insects; wbicli
seem, so fiir as the records go, to be uctunted nitber by ciiivulric sentiment,
than by animal passion.

Tribe II. brenthiki.

Two species of Brenthu* collected by Mr. Xantus, at Caprf Sm Lucas,
Lower California, which are closely allied to Mexican species, have been
fully descril)ed by Dr. Horn.* I observe in the males also jjn-at variation
in the form of the head in difTcrent indlviduils, althouijb the b'ak, though
shorter, is as slender in the cT 'is in the 9. iml the mandibles are ecpialiy
small, but different in form; the distance from the eyes to the insertiim of
the antenme is projwrtionally lon>!;er in tlie larger males.

Tlie head is deeply excavated beneath, just in front of the neck, in
B. petit riKular in, while it is only slightly so in B. hiciinnx. In B. mexl-
canus there is a short but deep groove in the same jiosition. Tlie front
femora alone are toothed in B. me.ticanus and lucanus, while they are all
toothed in peninsularis.

Subfamily 11. CYLADTDiE.

This sub-family represents the tribe GyladeK, of Lacordaire, placed by
liim between Eurhynchnu and Apioii, and consists of but two geui'ra, one
of which, Gylan, occurs in Asia and Africa, while the other, Myrmecacelu*,
is found in Australia. I have sufficiently exposed the characters of this
subfamily in the description of the family, and the singular f >nn of the
antenntc, as well as the very peculiar appearance of the ins.'ct, Wk enable
it to be easily recognized.

The relations of these insects with Brenthidce were well recognized by
Fabricius, Latreille and Olivier, and I know not for what reason they liave
been lost sight of by more recent observtirs.

liowever, the wings are found to be very well developed, and the elytra
not connate.

Family YIII. CALANDRID^.

Mouth cavity variable according to subfamily, as follows:

1. Gular peduncle very long, concealing the mentum and ligula, buccal
fissures narrow and long; mandibles comj)resscd, wi;h three apiail teeth
in Gala ml r Ida; (.(jenmni).

2. FUK>r of the mouth so prolonged that all of the organs are concealed,
e.vcept the mandibles, which are coave.xon the inner face, with three apical
teeth, and usually diverge externally in lihinidiv.

3. Gular peduncle rather broad, mentum trapezoidal, tmnsverse; maxil-
lary palpi rather large; mandibles flattened, curved, with the apex acute,
and one prominent tooth on the inner edge, in Cossonidm.

Antenna' geniculate. Inserted near the base of the beak {Calandridm),
or about the middle iRhinidcp and CoHnonidce); scape long, funicle vary-
ing from four to seven joints; club variable, with the basal part, and some-
times nearly the whole surface shining, not sensitive: oval and annulated as
usual in Consonidie.

Head iK)rrected, beak at most capable of being deflexed vertically, never
narrowed behind the eyes; beak sometimes long, sometimes short; eyes
sometimes small, sometimes very large and transvers:-, contiguous beneath
{1thi)iid(e\; antennal grooves very short, and not receiving the scape in
Calandridte, sudd( v deflexed under the eyes, and receiving the scape iu
CoHHonidw.

Prothorax truncate in front, not emarginate beneath, prosternum long in
front of the coxie, which are separated; prosternal sutures effiired; the
transverse suture between the coxte is wanting in Calandridce and Cosso-
nidie, but distinct in RhinidiP.

Mesosternum triangular, truncate behind, side pieces varying according
to genus and tribe; middle coxa^ separated, cavities rounded.

Metasternum usually long, episterna varying in breadth, broader in
front, epiniera large in some Calandridm, small in other genera and sub-
families; hind coxa; transverse, oval, not attaining the side of the abdo-
men.

Elytra w^ithout epipleurjE, exposing the pygidium in Galandridm, cover-
ing it more or less completelj' in the other subfamilies; 0:1 the inner surface

lon.ii;(r, with the suture nearly obliterated at the middle in ('(ilnnitridip,
but de(!p and entire in li/iinhlit; in Conitonidm they are very lonjr. "nd tlie
suture is cfTuced at the middle; the third and fourth sejrments are short, and
the sutures straight and deeply impressed; the fifth is about as long as the
third and fourtli united, and is rounded behind. The dorsal segments are
membranous, (xcept the last, or pygidium, which is large, nearly perpen-
dicular in Valandrida, oblicpiely iletlexed in the other subfamilies; the
anal seg'Ment of the rf is quadrate and retractile in CaUmdridiB and ZiVu-
nidip, broader and less retractile in Co»nonidie, but not continuous with the
pygidium as in Vareulioiiida and nreiUhidie;lh(i lateral edge of the nie:a-
thorax and of the ventral segments is sharp and fits into the lateral groove
of the i iner surface of the elytra; in the ('dsmnidd' this edge continues on
and around the last ventral, thereby showing a tendency towards the modi-
fication finally perfected in tlie Scolytidix, and of which we have already
seen trac 's in the lirenthidiv.

Legs UKxlerate, varying thougli not greatly, according to genus; thighs
usually stoutly davate, not toothed; tibiie rather short, strongly unguicu-
late at the outer angle. Tarsi frequently narrow and not brush like be-
neath; third joint sometimes bilobed, (7{Atwjrfrti) sometimes broad pateilate,
and not emarginate, (certain Sphenophori); claws divergent, 8imi)le.

I liave embraced in this family several very distinct forms which agree
with Vurculionida in general characters, but difler in having the genital
segment of the c? not articulated directly at the end of tlie last dorsal, but
either retractile or concealed under it. While the mouth organs of the Co»-
sonidit are similar to tliose of ordinary CureuUonidiP, and submit to modi-
fications similar to those of Ilylobiim for instance, in the other subfamilies
there are specializations which do not otherwise occur among Khynchophora.

With regard to the affinities of the membei-s of this family, it may be said,
in general terms, that the Cdlandridce show an alliance with the Barini;
the lihinidce continue the specialization still farther, and have not a direct
resemblance to any other tribe. The Consonidw seem to be a connecting
line from Ilylobiini to Scolytidce, to whicli they approach very closely in
Rhyncoluit.

Three subfamilies occur in our fauna, the characters of which have l)een
sufficiently indicated above: the following table will enable them to be
readily distinguished.

Buccal cavity elongate, peduncle of mentum elongate,

narrow : pygidium exposed CALANDRID.^.

Buccal cavity entirely at the apex of the beak; py-

Tribe I. KiiYKC'ifOPiioKiM.

The species of this tribe are of lars^e size, and with the exception of Rhyn-
cJiophontx, iiave the mandibles turned outwards as in the Rhiiiidiv; in the
genus just mentioned, the mandibles are of the usual pincer-form with three
small ai)ical teeth. The funicle of the antennie consists of six perfoliate
joints, strongly constricled at the outer end; the club is transverse, trape-
zoidal, corneous, with the terminal face flat, spongy and sensitive.

One species, 11 cruentatuit, represents this sjiecies in the Southern States.
It is jtarasitic on C'hamaropK pitlmetto. In consequence of the extension of
the mesothoracic epimera upwards, the humenil portion of the elytra is
truncated, as in Barini. The third joint of the tarsi is but little wider than
the second, not emarginate, fringed at the apical margin beneath. In the
(^ the tibia", and to a less extent the thighs are densely fringed with long
yellow hair on the inner side: in the 9 ••>« hairs are much less dense. The
genital segment is sometimes protruded; it is nearly smooth, and finely
channeled above in both st'xes, but is longer and narrower in the 9, in
which sex also the pygidium is more flattened, and more obliquely narrowed
at the tip .

Tribe II. NPIIEWOPHORIXI.

The species of this tribe are rarely large, but never very sraiill. The
mandibles are always pincershaped, with three apical teeth. The meso-
thoracic epimera are large, and truncate at the outer side, so tl t tlie out-
line of the elytra near the base is straight, and not Mi(|' :i8 in ilic preced-
ing tribe; the metathoracic episterna are rath
small, though quite obvious.

ation of prothora.v, but a little Htronj^er, imd the apical constriction is less
marked; the lustn; is more dull. S. roha»tior Horn, froni Texas, has the
form of prothorax of acupunctatus, but the punclures are coarser, and the
lateral ones are less elevated; the lustre is also dull as in S. interittUiali*.

SPHENOPHORUS Sch.

The species S. \^punctatHn and validu* contained in Horn's Group ii,
should each constitute a distinct genus; the other species, in which the
third Joint of the tarsi is not spongy beneath, but merely pilose, sometimes
broad, sometimes narrow, might be regarded as constituting but one genus.

OACTOPHAG-US n. g.

I would separate as a distinct genus a species of large size, and dull vel-
vety black color, which differs from Sphennphoru», by the absence of in-
equalities or coarse sculpture, and by the third joint of the tarsi being some-
what tnvnsverse, and uniformly densely spongy beneath; the first and sec-
ond Joints are narrow, and glabrous beneath. The tibiie are slender, not sin-
uate, and the outer part of the tip is regularly rounded, not at all truncate,
or angulated. The gular peduncle, though deeply channeled, is regularly
rounded at the end, not abruptly subtruncate as in Sphenophorun; whereby-
the beak remains cylindrical, and is not at all compressed at tip.

latter comparatively longer. The mesosternum is also narrower than the
other genera. The species are found on flowers, mostly rose-bushes; but
two are known to me in our fauna; the fli-st is red, with black spots; the
second bro'vn, irrorate with grayish rcund spots, which surround the punc-
tures.

Tribe IIL CALAXDREXI.

This tribe consists of small species, in which the mandibles are i)incer-
shaped, and not everted; the club of the antennie not compressed, and the
mesotlioracic epimera transverec, acute at the outer end, and intervening
between the luimeral part of the elytra and the base of the prothorax. The
anterior part of the last dorsal segment of the abdomen is channeled for the
reception of the suturai edge of the elytra, almost as in AnthribtdtP. This
is a very peculiar character, and I find no tracj of it in tlie other genera in
our fauna.

CALANDRA Clauv.

This genus differs from the others contained in the tribe, but not repre-
si-nted in our fauna, by the anfennal club '.•■eing oval, tlie corneous part sep-
arated from the sensitive [wvrt by a transverse line; the sensitive part being
convex, and somewhat pointed. The body is narrow, and elongate, (juite
different to that observed in the genera of the two preceding tribes, rather
resembling Itfuna in miniature.

Three species occur in our fauna; they have been distributed in the ce-
real grains upon wliich they depredate, so that tlieir original h-.bitat cannot

Founil in every part of the globe; universally distributed by commerce,
and said to have been originally derived trom Asia; it atfects rice, wheat,
and Indian corn (maize). The surface is dull, and the jirothorax densely
punctured; the elytra are usually ornamented wit li four red 8iK>ts, but are
sometimes red, witli the suture, side margin and tip darker.

Subfamily IL lUIINID^li:.

This siii)(amily corresi)onds nearly if not exactly with Laeordaire's tribe
iSipitfnfi's, and the essi-ntial ditferenccs between it and tiie CdliuKlridti' are
in the position of the buccal opening which is entirely tit the end of the
beak, not extending upon the under surface; tlie pygidium is not large and
pcrpeiulieitlarly declivous as in the last subfamily, but Ci)vered by the ely-
tra, which are conjointly rounded at tip; anotlier cliaracter also separates
it from Calnndrida (though not from Laeordaire's tribes 8lromho»eeride»,
and OryrhynchidcK, which arc not icpresenied in our fauna, and are un-
known to me in nature); tlie eyes are strongly granulated, very large, a'ld
confluent on the under surface of the head.

In nearly all the genera mentioned by Lacrordaire, tht; mandibles are con-
vex on the inner face, and liie apical teeth are everted, though tliis is pro-
babl}' a group or generic charaet'.r as in c(Mtain tribes of CdUnulridtv. The
club of the antennie varies in form accordini!: to genus, and is not annulated.
The tarsi also vary, the third joint being narrow in some genera, wide and
bilobed in others.

But one represenhitive occurs in our fauna, which indicates ti new genus;
allied to lihiuii and Htirpitclcni*-

YUCCABORUS n. g.

dinal grooves; aiiteiinal grooves very short; eyes transverse, coarsely granu-
lated, contiguous beneath, but widely distant above, and not extending to
the upper surface of the cranium. Antennie with scape reaching the eyes;
funiele ((-jointed, longer than the sciipc; dul) elongate-oval, as long as the
four inceeding joints; spongy |)art as large as the corneous part, and sepa-
rated from it liy angulated lines, so as to extend farther upon the sides than
upon the faces of the club, which is slightly compressed.

Proi borax longer than wide, rounded on tlie sides, a little narrower at tip
than at 'a.se, and constricted; truncate before and behind. Scutellum small,
rounded. Elytra with shallow punctured striie, interspaces wide, sparsely
punctured; c mjointly rounded at tip, i)ygidium s'.iglitly prominent. Legs

strongly uiigiiiculate; tarsi slender; third Joint a little wider, bilobed, not
spongy bencalh, but smooth and gtabror.H like the others.

This genus dilffrs from the two above mimed by the form of the antennal
club, i)y tlie eyes being widely distant above, and by the third tarsal joint
much smaller, not siK)ngy beneath.

species, that it might indicate a distinct genus; but my knowledge of Jihi^n-
chophiira at that time was not sufficient to enable me to pr()|»erly define it.

Subfamily III. fOSSONIDyE.

The abnonnal form of mouth seen in the two preceding subfamilies is
here replaced by the ordinary buccal cavity and mouth organs si'en in
Curcidiiniiilir. The gular peduncle is rather broad, not very long, the
mentntn and lignla witli its paljii are distinct, and modcratc^ly large, and
the ma\illa' and palpi are well deveioiicd. The beak varies greatly, being
somelimi's rather long, and moderately slender, sometimes so short and
stout as to become indistinct. The antenna' are inserted at a variable dis-
tance, being sometimes basal, some;iines nearly ai)ical; tlie scape generally
extends licyond the eyes; the funiele has from four to seven join s; the club
is small, oval, partly corneous in some genera, and but feebly annidatcd.
The front coxa' are sometimes widely se| araled, .some'imes almost contigu-
ous. The thighs are unarmed, and the tibia' are aimed in our genera witli
a long curved spine at the inner apical angle; the tarsi are varialile, the
third joint is nsnally not broader; in oic genus, Dryophthoriis, by an ex-
ception ollierw isc unknown in the family, and repeated again only in I'laty-
pus and s>iine other genera among the Scolytidie, the tarsi arc distinctly
5-jointed.

Neglecting the number of joints in the ftuiide of the antennie as being
ratlier of generic than tribal value, 1 would divide the few genera repre-
sented in our fauna as follows:

I have associated with Drynphthorm two other genera which have but
little in comn\on witli it or with each other, except the following characters,
by which Ihcy difler from other donKontdir, and approach other group.s of
Bfii/nrhop/iora. The beak is longer (hiin the head, not v.'ry stout, cylin.
drical, not dilated at tip, and tiie buccal cavity is smaller; the gular pedun-
cle and mentnm are smaller and narrower than in tin- other trilns. The
tibise are s'ender, not at all dilated, and the terminal h(M)k is long. The
botly is coatsely sculptiued. and covered with a dirt-colored crust.

Grouj) I. l»ryo|»hlhorl.

A single small si>ecie.s, represents this group in our fauna. It resembles
in form Calandra, rather than any genus of CoMonidie known to me. The
antennal c'ub is rounded, oval, corneous, except the lip, which is spongy
and not annulated; the joints of the funicle are only four, while those of I ho
tarsi aie distinctly live, though in the South European Cliivrorhinux, ac-
cording to description, tliis anomaly disappears, and the tarsi aie 4 jointed.
The metasternum is long and the side pieces are narrow; the tiist, second
and rtflh ventral segnn iits are very large; third and fourth excessively
short, shorter in fact than in any other genus I have examined. The
antenna' are inserted very near tiie eyes, which are coarsely granulated and
transverse.

genus would probably go near LymanteK, which is Ihus tiir unknown to us,
and may perhaps liave some relation to the European Styphloderes.

BesiilLs the luoie slender beali, and the crusty covering, these insects dif-
fcr from lliose of tlie following two tribes by tlie head being rather peculiarly
CDnstiictcd behind the eyes, which arc small, rounded and very coarsely
granulated; the result of this form of head is that the eyes are situated on
tlie beak, instead of at the sides of the cranium i)roper. The scutellum is
not visil)Ie in eillier of our genera, and I am inclined to believe that this
will be found a cliaracter of the group, permitting the association of forms
now widely separated.

Tribe II. COSSOSflXI.

I would associate as a distinct tribe certain other genem, wliich have not
the body covered with a crust, l)ut siiining and bare; .some of the foreign
geneni are more or less seto.sc, but ours are glabrous.

The beak is never very short, and is freciuently dilated at tip; the anten-
nic are inserted near the tip, or at the middle; the antennal grooves fre-
quently descend rapidly on the sides of the beak, and sometimes are di-
rected towards the eyes, but the antennje are not received in reiKise in a
deep transverse gular irroove as in the next tribe. The club varies in form,
and in our genera the funicle is 7-jointed; whether any of tiie genera ol
other countries, with less number of joints in the fuiucle, Iwlong to the
tribe is here constituted, must be determintd by subscfpient investigalioijs.

The arrangement here proi>osed diflers radically from that otTered by Mr.
Wolliiston, and, if found in accordance with natural affinities, will result in
a great reduction of the numlHir of genci-.i.

The geneni I recognize in our fauna are as follows:
Body not d<!pressed, beak nr)l dilated at tip.. 2.

HOMALOXBNUS Wollaston.

H. dentipes Woll., Tr. Ent. Soc. London, 187*3, 015.

Florida: a single siieoimen, collected and kindly given to mc by Baron
U. Osten Sacken, agrees so perfectly with tlic description of Mr. Wollas-
ton of his specimen from S. Donjingo, that I am not warranted in consid-
ering it as distinct. The only ditference seems to be that in my specimen
the thighs, tliough verj' thick, are hardly percei)tibly toothed; this chamc
tcr may, however, be .sexual. The insect will be easily recognized by
the very depressed form, l)rown color, with dull lustre; very slender beak,
as long as the prothorax; slender antenme; soircely mucronate tibia;, end
very widely dilated and bilolted third tarsal joint; characters of iiire occur-
rence in the present sub-family, but combined with a general nppoaranc,'
which renders the afflnities with this tribe unmistakable.

OOSSONUS Clair V. (emend. Wollaston.)

To this genus, as now restricted, belong the eight species comprised in
group A, Horn, Pr. Am. Phil. Soc. 437. An excellent table of differences,
also the bibliography and full descriptions are there given. The fuuicle of
the antenna' becomes gradually stouter, and the dilatations of the ajjcx of
tlie beak less eviilent from the first species (platalea), to the eighth (//«-
pretxifrons), thus establishing an imperceptible transitiim to Boropfilwus
Woll. So far as I may judge without C(»mparison of speciuK'ns, I do not
see why B. miiwr Woll. Trans. Ent. Soc. London, 1873, 027, may not be
referred to the species determined by Horn as G. corticola Say.

MAORORHYNCOLUS Wollaston.

To this genus I refer the Californian Ehyneolax protractux Horn, Pr.
Am. Phil. Soc. 1873, 444, which ditlers from the true Uhyncoli, not only
as stilted by Horn, in tlu; widely sepanitod front coxa; and linear form, but
by the longer cylindrical beak, which is quite distinctly separated from the
head. The third joint of the tarsi is narrow and fi ebly bilobed.

MACRANOYLUS n. g.

The number of genera in this tribe has been increased to such an extent
as to render them extremely difHcult to recognize. I am quite unwilling to
add to the names already published, imtil an attempt has been made t(»
combine them into larger groujjs. It is for this reason that I regret to pro-
[)ose this genus tor an extremely slender but cylindrical (not depressed)
BtHJcies, which has the beak stout, not sepamted from the front, gradually
but slightly tapering externally. The antennal grooves commence about
the middle of the beak and the anteniue arc inserted b''hind the middle;
the scape is long, extending to the back part of the eyes, and is rather sud-
d(!u'I5' bent and thickened from the middle to the tip; the funicle is moder
j.tely stout, the first joint larger and thicker; the remaining joints short,
closely united, gradually but very slightly broader; club oval, pointed,
rather small, distinctly annulated in tlie outer half. The antennal grooves

gradually dilated and the front pair are pubescent towards the tip; a ilis
linct spine is seen at the inner apical angle; terminal hook long; tarsi with
rather broad joints, third a little wider, feebly bilobed, last joint longer
than the others united; claws large, divergent. Seutelluni distinct, elytra
with punctured stria;, which are deeply impressed near the tip.

1. M. linearis, n. sp.

Very elongate, cylindrical, piceous or brown, shining, glabrous; head and
beak finely punctured. Prothorax more than one half longer than wide,
more strongly but not densely punctured, without impressions; slightly
narrowed in front, sides nmndcd near the base. Elytra not wider than
prothorax, stritc coniposed of approximate punctures, deeply exarate on
the posterior declivity for a short distance. IJeneath distinctly but finely
punctured ; flanks of prothorax feebly concave in front. Antenna; and
legs reddish brown. Length 3 mm.; .12 inch.

is longer than the third and fourth united; the three together are scarcely

longer than the first and second; the first ventral suture is obliterated, even

at the sides.

ALLOMIMUS n. g.

I cannot refer Cossomm dnbius Horn, 1. c. 442, to any of the genera
described by Wollaston. It is nearly alii ^ to Macranrydm, but is of less
elongate form, and very much more coar , y sculptured; the elytra are in
fact rather sulcate than striate, though the deep striie ore coarsely punc
tured, and the interspaces narrow with single rows of small punctures.
The beak is stout, cylindrical, a little narrower than the head, and nearly
as long as the prothorax; the antennal grooves cimimence in front of the
middle, and run directly towards the eyes, which are small, rounded,
moderately convex and not very finely granulated; the anlenniv are not
very stout, the scape straight, strongly clavate, extending to the front mar
gin of the eyes; funicle 7-jointed, first joint a little larger and stouter,
remaining joints short, closely united, gradually but slightly broader, club
large, oval-pointed, pubescent, ann'ilated. Scutellum distinct. Front
coxa; widely separated; thighs rather stout, tibia; dilated, with a small spine

The genera of this tribe while differing from those of the Co»i>onini only
by having the prosternum very narrow between the coxa?, and by having a
deep transverse gular groove beneath in front of the eyes, exhibit other
characters which slvow a strong approximation to the Scolytidoi ; thus i
number of joints in tlie funicle of the antennue varies so as to be barely of
generic value ; the beak becomes very much sliortened, and the head
comparatively larger, as in Stenoscelin ; the form of the club varies,
tiecoming wedge sliai)ed, truncate and spongy at tip in WoUastonui, thus
iiicalling tiie form seen in Iihynchophoru», &c. ; quite rounded or i)erlia|;a
a littli! transverse in Htenoscelis. Tlie form is also that of certain Scolylidir.
Ithyntolut resembles closely one section of Ilylnstos, while Stenoscelis \\x\9
altogether the appearance of Hylurgopn {II. rugipennis, &c.).

As in the Uhynchopliora, from the nearly jierfect representation of past
and present forms, there are almost always intermediate genera to be
found, I would say that Phhrophagus seems to be one of such interme-
diates, and would be in place in the preceding tribe, if I did not regard the
approximate front coxa- as having greater systematic value than the longer
beak and the weaker gular groove.

The antennal grooves always commence near the ti)) of the beak and
descend obliquely below the eyes.

Our genera may be separated as follows ;

Tlie Insects of this family are mostly of cylindrical form, and small size-
They are the most formidable enemies of trees, sometimes devastating the
Ibrests, especially of conifers, by appearing in incredible numbers: the bur-
rows are cluetly between the wood and the bark, though some genera pene-
trate mont i\('c\)]y (Xylotere^, §r). The patterns mad(! by them arc comphfx
and vary according to genus and species; those of several EurojK'an species
arc figured in the excellent work of Ratzeburg,* and since descriptions of
our siwcies are now accessible, so that tluiir identiflcatlon is easy, I trust
that those interested in the preservation of our forest trees may direct their
attention to this imiK)rlant subject. Specim -ns of the ravages of these in-
sects should be carefully colletrted, with individuals taken from the bur-
rows, and these should be dei)09ited in some museum where they will be
carefully jireservcd for future study.

Since the publication of my revision of this family, f a few additional
species have been found, and a renewed study of the genera has rendered
necessary some modilication of the classification there proposed.

The great dilferences exhibited by Platypus, and its allies, indicate the
propriety of separating them as a distinct sub-family, a course already
adopted by Lacordairc.

Sub-fiimily II. SCOLVTID-IS (geimini).

The characters by whicli this sub- family differs from the Plati/podidieluwv
been already sufflciently pointed out; in other respe<'ts tlie species ditfer
greatly according to genua and tribe, and the chief iKJCuliarities will be
pointed out under the appropriate lutads.

The genera which occurs in our faima indicate the following tribes:

1. Prothorax not prolongcnl over the head, which is oblong

and prominent; tai'si with fourth joint smaller or in-
distinct; third joint usually bih)bed t.

Prothorax prolonged over the head, which is deeply im-

mersed and globose; tarsi filiform, 5 jointed TOMlt'i^vl.

2. Ventral surface ascending ol)li(iuely Ki'Ol.VTl.<VI.

" " regularly cylindrical IIYI.KMI.VI.

Tribe I. tomicixi.

Although the genera of this iribo are the farthest removed from Con-
Honidie by their characters; they are in some respects the most nearly allied
to Plttlypun, with which the family must naturally commence, on account
of the relations between the latter and JRrenthida.

The head is globose, or nearly so, and deeply immersed in the i)rothorax ;
the eyes are transverse, sometimes divided, (Xi/loleru»): the front is not
prolonged into a beak; the antennte are inserted near the base of the man
dibles; the scajie is long and stout, the funicle short, coni|)osed of from one
to five joints, the mass large, compressed, varying in form and structure ac-
cording to genus. Prothorax more or less cylindrical behind, prolonged in
front over the hi-ad aid much rounded, so that the anterior ope liiig be
c)mes very oblii|ue, or even s )metimi's, ahn'>sr horizuiUii; t'le .sculpture is

PITYOPHTHORUS Eichholf.

Under this name I would associate most of the species which I formerly
called Ci'uphalu*, but which differ tVoni Cri/phitlus tilke by having the
sutures ot the anteiinal club transverse, nearly stniigbt and visible on both
sides, insti'ad of strongly curved, as in that s|)ecies. The funicle of the an-
tonntc consists >f two parts; the first joint rather large, as usual, and about
us wide as long; the rentiiinder is narrow at base, gra<hially becoming
broader, and forming a stem to the dub; this stem is divided by three
transverse sutures which arc frequently very indistinct, and I consider
tiicir number as liaving little value

The front tibia are c impressed, with o.ie acute outi r edge, but no flat-
tened »\M\i*' as in M'nKirthnim; this eilgu is very ferbly serrate; the joints
l-;i of tlK tarsi art "Mbcfiiial and rather .stout, the fourth is small; fifth about
as long as the othcrr unit d; claws large, divergent.

head nearly smooth, broadly and deeply concave, thinly fringed with not
very long yellow hair. The species is easily recognized by the large ellij)-
tical i)atch of yellow hair each side of the prolhorax, and by the tine dis
tant rows of elytral punctures; the declivity is not retuse, and the sutural
.stria is deeply impressed. The club of the antennu' is divided by three dis-
tinct straight sutures. I am not certain of the numbir of divisions in the
oviter part of the funide. Length 1.8 mm.; .07 inch.

It is i)ossible that P. infam Eichhotf, Berl. Ent. Zeitsch, 1871. 135, may
be the J of this species. It is, however, unknown to me, and 1 have seen
nothing that corresponds with the description.

HYPOTHENEMUS Westwood.

The species I refer to this genus agree in having the outer part of the
funiclc of the antennas very short, shorter in fact than the first joint, and
very indistinctly divided; in the first species only by one transverse suture;
but in 11. disiimilis, the divisions seem mori' niunerous, probably three,
but so indistinct that they are without value. The head is larger and
more cxserted than in tlu^ preceding genera; eyes narrowly emarginate,
the club of the antennte is round, compressed, moderate in size, and di
vided by straight sutures on both sides. The tarsi are distinctly ."i-jointed,
the third joint rather longer than the first or second; the fimrth small as
usual; fifth elongate. The tibite are distinctly serrate towards the tip. The
declivity of the elytra is not retuse or sulcate.

comjdetely divided, and the club of Ww. antennaj is oval, solid, pubescent
on both sides, and not annulated. The tibia; are broad, roundtsd at tip,
and serrate on the outer and terminal edge. The tarsi are slender, the

thus injuring the timber much more than the subcortical Tomiei.

3. X. snabricoUis Lee. Trans. Am. Ent. Soc. 1868, 158.

District of Columbia, oae (f ; Mr. Ulke. Tliis species has entirely the
form and sculpture of X. bioittatus, except that the prothorax instead of
being punctured behind the middle, is covered with flat granules, produced
by anastomosing rugie, and the front part is as rough as in the 9 of X. bi-
eittatun. The striic of punctures on the elytra are also deeper, and the color
is different; the head and elytra are piceous, and the prothorax dull, ferru-
ginous; the antenufU and legs, as usual, are yellow testaceous. Length 3.5
mm.; .14 inch.

Massachusetts to Kansas and Georgia. Length 3.3 mm.; .13 inch.

I have received specimens from Mr. J. A. Linlner, as depredating ujwn
maple trees. Easily known by being more hairy than the other species,
with the interspaces of the elytra sparsely punctured, so that the rows of
punctures appear confused. I observe no sexual difterence in the specimens
before me, and the species may readily t)e separated as a distinct genus, by
any one who will avail himself of the characters in the antennal club,
which I have pointed out above.

X. unicolor Eichhoff, Borl. Ent. Zeitschr., 1871, 130, is unknown to
me, but seems to be allied to X politus.

Group III. Xylebori.
The essential character of this group is that the club of the antennro is
entirely corneous, and not articulated on the inner surface; on the outer
surface it is also corneous, except towards the distal end, where it is ob-
liquely truncsite; the truncate surface is pubescent and sensitive, and has
three concentric or transverse sutures, which indicate the other joints of
the club The scape of the antennie is elongate, and the funicle usually
distinctly .T-jointed, though in some species there appear to be but four
joints. The tibiaj are dilated, more or less serrate, and spinose on the outer-
margin, with the apex obtusely rounded, and the inner angle not very
strongly ungtiiculate. The tarsi are slender; fourth joint small, fifth nearly
as long as the others united; claws strong, divergent, simple.

Group. IV. Toinlei.

The species of this groui) are of C3iindrical, but not very slender form,
and are easily recognized bj' the deeply excavated elytral declivity, which
is shari)ly margined and acutely toothed. Tlie club of the antennre, as in
the group Xylebori, is entirely corneous on the inner face, but is not ob-
liquely truncate on the outer face. The sensitive surface is more or less
distinctly defined, and is divided by two sutures which are more or less
curved or angulated in our species, but are described in some European
species as straight, thus showing an affiliation with Dryocietes of the prece-
ding group. The tibiffi are coarsely serrate, and the tarsal joints 1-3 are
rather stouter than in the preceding groups.

Our species represent l)ut one genus, which m'\y be divided conveniently
according to the form of the sutures of the antennal club.

Atlantic region, as far west as New Me.vico. The usual size is 5 mm. ;
.20 inch, but two specimens from the locality last mentioned measure 6.4
mm.; .25 inch. The sutures of the club resemble ligure 1, Fcnrari, p. 44,
and are quite like those of the European T. stenographv,i ; which dirt'ors
bj' its larger size, more coarsely punctured prothorax, and especially by
having but two teeth on the edge of the elytral declivity behind the most
prominent tooth.

For the purpose of making the distinc tions between the species mentioned
below more intelligible, I will describe the arrangement of the teeth in
this species, in which the number is greatest. The declivity is deeply con
cave, polished, sparsely jiunctured, and the prolongation of the sutural
stria is well impressed. At the posterior end of the second interspace is a
small cusp, and a similar one at the end of the third intersjiace ; these two
small cusps or denticles are not mentioned in the synoptic table given
above. At the end of the fourth interspace is a large conical tubercle,
which in this species is but slightly connected with the tubercle of the fifth
interspace, which in always the most prominent. Behind this prominent
one there are in the present species three acute equidistant teeth, and the
ajiical acutely elevated margin. The disappearance of some of these teeth
in the following species is produced by their absorption in the acute ter
minal margin, which thus becomes longer, so that in T. pini it extend."*
around fully one-third of the declivity.

The dimensions and relations of these teeth with each other, and the
arrangement of the sutures of the antennal club give excellent characters
for the discrimination of the species ; and I hope that the student will have
no difficulty in recognizing those I have admitted in this memoir. The
descriptions of those named by Mr. Eichhotf are, however, too indefinite
for me to venture to pronounce with certainty upon their affinities ; they
seem, moreover, if I may Judge from the short diagnoses, to have been
unduly multiplied upon individual differences of slight importance.

Southern and Western States. Similar to the preceding, but usually of
.smaller size, (3.5-4 mm.; .14-.16 inch); the cusp of the second interspace
is very small, anil that of the third is wanting ; that of the fifth is com
pressed and scarcely more prominent than that of the fourth interspace
and is somi-wh.it connected with it ; there are but two teeth between
the tooth of the fifth interspace and the terminal acutely elevated margin,
and thes(! teeth are all of them less prominent than in T. calligraphus, in
some specimens (J^), but equally jirominent in others, 9> those less acute
than in T. enUgraphus. The interspaces from the third outward are
marked eacli with a regular series of punctures behind the middle, whereby
it diflfers from the next species. Tiie club of the antenna; is quite similar to
that of T. CAilligraphuK.

3. T. confusus, n. sp.

Quite like T. cucographux, except that the elytral strite are composed of
larger and more transverse punctures ; the punctuies of the interspaces are
very distant as far as the middle, but become irregular and confused with
tiie strire behind. The teeth on the margin of the declivity are arranged
just as in T. cacographus, but are larger and stouter, and the one of the
fifth interspace has a tendency to become curved at the end. The club
of the antennie as in the two preceding species. Length 4 mm. ; .16 inch.

Southern California and Arizona. I have seen but three specimens.

4. T. plastographus Lee, Tr. Am. Ent. Soc. 1868, 163.

Middle California and New Mexico ; two specimens. This species closely
resembles T. confusus in the sculpture of the elytra, the interstrial punc-
tures being confused behind, but on the inner interspaces from the third to
the fifth there are no punctures except near the declivity. The tooth of the
fourth interspace is more compressed and closely united with the very
prominent tooth of the fifth interspace, which is cylindrical and obtuse ;
there is but one tooth between that of the fifth interspace and the apical
elevated margin, but this is large and conical. The sutures of the antennal
club are very strongly angulated. Length 4.5 mm.; .18.

broadly rounded, margined only near the side ; anterior half of disc
asperate with granules ; posterior half strongly and tolerably densely
pun(!ture<l, without distinct dorsal smooth apace. Elytra with strife com-
posed of strongly impressed transvc^rse punctures, interspaces wide, 1-7
smootli except near the declivity, where there are a few punctures ; outer
interspaces witii i)unctures gradually becoming contused near the sides ;
declivity deeply concave, strongly and coarsely punctured, with the
sutural stria deeply impressed ; the teeth of the second and third inter-
simces are small, but acute ; that nf the fourth is larger, coni('al and sub-
acute ; that of the tifth is large, compressed and emarginate ; the inter-
val between it and the apical elevated margin is wide, and in some speci-
mens is marked by a single indistinct cusp ; the apical margin is long, and
its anterior angle is more i)rominent than usual ; the sutural angle is
slightly prominent, as is frequently the pase in other s|)ecies, a character
of no importance. The sutures of the antennal club are nearly straight,
slightly bent forwards at the sides. Length 6.0 mm. ; .20 inch.
Oregon. Found in abundance by Lord Walsingham.

0. T. rectus, n. sp.

This species resembles the preceding in form and color ; but is of smaller
size, and the prothonix is less decsply punctured behind, with a distinct
smooth medial space. The elytral stria; and interstrial punctures are
similar, but the teeth of the declivity are ([uite dilferent ; the cusi)s of the
second and third interspaces are small, but distinct and acute ; that of the
fourth is broad, compressed and closely united with that of the fifth, which
forms a prominent tooth at its posterior extremity, the anterior extremity
of this conjoined mass is not acute, but barely rectangular, and the apical
acute margin is a rather large acute tooth. The body is thinly clothed
with long yellow hair, especially in front and behind. The antennal club
is marked with three sutures, the first and second curved at the middle,
bent forwards at the side, and the third nearly straight. Length 4 mm.;
.11 inch.

One specimen, New Mexico and two from Oregon. I should consider
these as badly developed specimens of T. plastographus, except for the dif-
ferences in the antennal club.

The elytral striie are composed of small, transverse punctures; the inter-
spaces are wide and flat, and are nuirked with only a few punctures near
the declivity; the latter is deep, strongly punctured, as in all the preceding
species, with the sutural stria deeply impressed; the tooth at the end of the
second interspace is small, but acute and distinct; that of the third is want-

Nortliern and Western i)art of Atlantic district, extending to Canada and

ii'iiicates tliis as the one described by that author. It is destructive to
Nortliern i)ine foreats in the same manner, but, as far as observation yet
goes, to a less extent than T. cdcographus is in the South. I have tiicre-

so great destruction to the pine forests of tlie Southern States.

Specimens of a larger size (5 nun.: .10 in.), from Hudson Bay Terri-
tory have the elytral stria; composed of much larger punctures, than in

name, were it not that the sut\ires of the antennal club are not bent forward
at the sides, but are nearly straight.

of still larger punctures than in the latter, and the punctures of the inter-

The scutellum is described by Eichhoff as smooth, but in my specimens
it is as distinctly channeled as in the five specimens of T. interruptua; as in
fact it is in all the preceding species except T. calliffrapJius and marginatut;
this channel is less distinct in T. plastographua than in the others, but at
best, is an illusive character of but little worth.

Alaska, one specimen. Very similar to T. interruptxn, but the punctures
of the elytral striue are larger and more distant, and those of the interspaces
nearly as large, though less numerous. The head is more finely granulate,
strongly retuse in front, with a broad frontal groove. This character is prob-
ably sexual rather than specific.

elytral striae are composed of close-set quadrate punctures; the interspaces
are wide, and as far as the sixth have only a few punctures near the declivity ;
the latter is more abrupt than in the others, and nearly perpendicular, but
deeply concave, and coarsely punctured, as usual, with the sutural stria
deeply impressed; the tooth at the end of the second interspace is small, but
well defined; that of the third is wanting; those of the fourth and fifth are

ridge is long, and between it and tlie last mentioned tooth is an acute tooth
which is eriuaily ironiincnt. The prothorax is nearly as long as tiic elytra,

California, at Lak-J Taiioe; Mr. C'rotcii. Tids species is smaller t'\ mm.;
.14 inch), than T. jtini, and of more slender form. It is easily distinguinheil
from all the other species by the much more deeply concave declivity of
the elytra; tlie cusp of the second interspace is acute; the teethof thefourtli
and fiftii are united together, forming a ridge wiiicii lias three distinct
cusps, of which the middle one is more prominent; the tooth be
tween this ridge ami tlie terminal margin is unusually prominent. Tlie
stria are composed of deep close-set punctures, and tlie intersjiaces are
marked with rows of small punctures. The sutures of the antennal
club are nearly straight.

Alaska, three specimens. Length 4.2 mm.; .17 inch. A very distinct
species, with tlie elytra confusedly punctured; tlie declivity obliipie, nearly
flat, punctured, with the sutural stria scarcely distinct; the teeth are but
three each side, of which the anterior one is small, and the third longer
and larger than the second.

Group V. Micracldes.

The funicle of the antennae is C-jointed, the outer joints broader; the club
is pubescent and usually marked with sutures on both sides, as in the group
Gorthyli, but these sutures are usually very much curved, though some
times nearly straight ; the basal joint is long, and in one sex is fringed
on the front margin with very long hairs ; the eyes are transverse,
coarsely granulated, either distant or contiguous beneath. The protho-
rax is produced over the head, rounded and asperate in front, and its
anterior opening is very oblique as in most Pttyophthori. The elytra
are usually punctured in rows, convexly declivous behind, then con
cave near the tip, and sometimes asperate with small gr^ules ; the
suture is produced into a sharp point, except in T. fimbricornis- The tibiie
are compressed, armed with a terminal hook, outer edge acute, not at all
toothed (or but slightly so in M. rudis), and fringed with long hair; the
front pair are as broad at base as at tip ; the joints of the tarsi 1-3 are
rather stout in all the species except J/, hirtella, where they are longer and
more slender, the fourth joint is small, and the fifth long, slender, with
divergent simple claws. Although important structural differences are
seen in the species, I regard them as constituting but two genera. This
group is excellently defined by the O-jointed funicle, and the broad parallel
front tibiae.

Lancaster County, Pennsylvania. Abundant in twigs of hickory; easily
recognized by the characters given above. The first and second ventral
segmcnis are each as long as the others united; third, fourth, and fifth short,
equal, last dorsal sligh'.ly visil)le from beneath. The bristles are not striate
as in Ilj/pothenemm, but linely granulated.

Tribe IL s€OI.YTI9ri.

The species of this tribe are easily known by the peculiar conformation
of the ventral surface, which is, namely, flattened or concave, and obliquely
ascending from the posterior end of the first segment to the fifth ; the first
and si'cond segments are closely connate, and the other three are separated
by straight sutures, about equal in length, and united are hardly longer
than the oblique part of the second segment. The antennal club is pubes-
(ient on both sides, nearly solid and marked with indistinct but strongly
(Uirved, or rather angulated, sutures; the scape is short, the first joint of
the funicle rounded, the remaining joints (five in number) closely united
forming a pedicel to the club. The thighs are stout, the tibioe rather broad
and compressed; the front pair are not serrate on the outer edge, which is
(juite sharp ; the outer apical angle is armed with a long curved hook, and
the inner angle is nearly rectangular but not armed with a spine ; the outer
margins of the middle and hind tibitii are feebly serrate, they are truncate
at tip, and armed with two spines or spurs at the outer angle, and a much
smaller spine at the inner angle ; the tarsi are slender, as long as the tibine ;
the third joint is deeply bilobed, the fourth small, the fifth long, with
simple divergent claws.

The side margin of the prothorax is distinctly defined, a very rare
cliaraeter in Rhynchophora, and the front coxie are separated by the pro-
sternum, which is very short in front of the coxie. In some ot the species
the ventral segments of the ^f are ornamented with spines, or acute tuber-
cles such as have been already mentioned in Proctorun (p. 212) and Pla-
typus (p. lUIl).

But one genus represents this tribe.

Tribe IIL ItYMKiaXl.

In this tribe the head is exposed, not covered by a prolongation of the
prothorax ; the latter is truncate in front or but slightly rounded, and not
differently sculptured. The antennie vary in form according to the group,

and in Ilylastes assume very much the same form as in Conxonidie, to
wliicli some of lljcse insects boar a stnmg resemblance. Tliey may l)e dis-
tinguislied, liowever, by the conipressed and serrate or spinulose tllna'.

Tlie third joint of the tarsi is frequenlly dilated and bilobed, and the
fonr;h joint, less connpicuous than in the preceding tribes, is sometimes
qiite indistinct. The first and second ventral segments are always
separated by a well-defined straight suture, more deeply impressed than in
Tom'cini.

The prothora.v is bisinuate behind, with a well defined antescutellar
angle in some of the species of all the groups except Ilylastes. They thus
manifest a tendency to the J./i^Ar/ft/rfte [Ghorayus, &c.), as Ilylastes does
towards the Cossonidm.

In several genera the front co.\nj are separated by the prosternum, and
in Dendi'octonus and the allied Europoa'.i genera Ilyliirgm and Blastopha-
giis the second and third ventral sutures ire curved backwards at the sides.
In Ilylastes the prosternum is deeply e.vcavated for the reception of the
short beak. In all these characters resemblances are seen to different
tribes of CurcuUonidm.

Group I. Polygraphl.

This group is sufficiently defined by the club of the antenme being large,
strongly compressed, pubescent and sensitive, and without sutures on both

The tibiic are broadly dilated, obliquely rounded at the ajiex, and finely
serrate ; th j third joint of the tarsi is not bilobed, and the fourth, though
small, is distinct. The basal margin of the elytra is acute and serrate.

between the two parts into wliich the eyes are divided ; in others these
are entirely absent.

Apate {Lepisomus) brevieornis Kirby, loc. cit. 194, may belong to this
gjnus, and would differ by the shorter antennse with smaller club. The
type is unfortunately in bad condition, and quite irrecognizable.

Oroup n. Phl«eotribl.

This gr.Hip is intei-mediate between the preceding and the following, and
ditlers from both by the antennal club beiag composed of three sei>arate
joints, which in Phlceotribus form a lamellate ma s, and in the European
genus PhlmophtJwrus a loosely articulate club as in many Clavicornia. Dr.
C lapuis describes the antennte as frontal ; but I see no special difference
i I their position from that observed in the preceding and following groups.
The head is but very little prolonged in front of the eyes, and there is no
preocular groove for the reception of the scape of the antenna; such as is
o')S2rved iri the two following groups. The iibiHB are dilated, compressed,
o')liquely rounded and serrate at tip, wi h the inner angle slightly mucro-
nite; the tarsi have the joints 1-3 short, gradually a little wider; third
not emarginate ; fourth very small ; fif.h as lo;ig as the others united, with
divergent simple claws. The basal margin of the elytra is acute and
serrate.

Tlie eyes are transvet*se, oblique, and not eniarginate. Two species are
known to me ; bbtli clothed with stifT pubescence.

A. Lamellate joints of club very long ; tibiae finely serrate.
Elytra with striie of large punctures, interspaces nearly

depredating on mulberry. I have mentioned Phlaotribus iietulo»uit and
dubiut Eichhofl; (Berl. Ent. Zeitschr. 1868, 149), as synonyms of this spe-
cies ; but fVom the memoir of Dr. Chapuis, above cited, I learn that these are
really South American species. The locality given by Mr. Eichhoff" is there •
fore incorrect, and. his descriptions are so Indefinite as to render my error
quite excusable.

This species is of the same size and form as the preceding, but is readily
recognized by the diftercnccs In the antennal club and In the sculpture of
the prothorax and elytra.

In this group the form varies from oval to cyllndrlcAl; the antennae are
iiiserted at the sides of the fh)nt, Immediately before the eyes, which are
large, transverse, slightly or not at all emarglnate, and finely granulated.
The scape of the antennre is long, and is received In a narrow, transverse

mandibles are stronger, nearly flat above, and tlu! labruni is obsolete; these
characters indicate a recurrence towards the normal Kh^ncbophora. The
funicle of the antennas is 5-7-jointed; the first joint stout, the others slender,
closely united; the club is very slightly compressed, annulated and pubes-
cent, oval-pointed in Ilyleninm, circular, compressed, nearly ghibrous, with
transverse sutures in Deiulroctonm. The ventral segments are convex,
nearly equal; the first and fifth somewhat longer, the sutures deep and
straight. The tibia; are dilated, and strongly toothed except in Cimsi/nus,
where they are not serrate; the third joint of the tarsi is usually bilobed,
and the fourth very small; the fifth long with divergent simple claws.

The basal margin of the elytra is elevated and acute as in the two preced-
ing groups, and the prothorax is narrowed from the base forwards.

I have already sufficiently described this remarkable genus, which is at
once known by the widely separated front coxa;, and the longitudinally
aciculate prothorax. Dr. Chapuis is in error in describing the tibiiC as
"extus imegerrima;;" the front tibiie have three acute teetli directed back-
wards, of which the third is apical, and the others near the apex ; the
outer apical angle of the middle tibite is produced, and emarginate at tip.
The third joint of the tarsi is visible but not conspicuously emarginate; the
joints 1-3 are rather stout, nearly equal, and the fifth is shorter than the
others united.

by the muricate punctures of the sides of the prothorax ; the basal edge of
the elytra is also more strongly serrate. There is no such difference in the
depth or punctuation of the elytral striie as to warrant the diflerential
phrases used by Dr. Chapuis. It is found also in Wisconsin and Georgia, ac-
cording to Eichhoff, and seems to me to be barely distinct from the follow-
ing species.

So far as the distinctions exist between this and the preceding, they arc
well exhibited in the descriptions of Eichhoff; to whom, however, the de-
scriptions of Say seem to have been unknown. It has happened unfor-
tunately that Dr. Chapuis has applied Say's name to the less known form
called imperialis by Eichhoff, and retained j»'ui>iosii,s for the present well-
known and widely diffused form.

The Munich Catalogue has added to the confusion by citing Say's de-
scription under the genus Bendrosinus (2073), and placing II. ijlobosus
Eichhoff, as a synonym. The latter is probably a South American sjiecies,
described by Eichhoff, with an incorrect locality, since a variety of it is
mentioned by Chapuis (p. 28) as occurring in Columbia. Length 2.2-

ditference. The elytra are not banded as in the preceding species, but
confusedly tesselated. I observe no sexual characters, and the front is
finely carinate in the four specimens examined. The head is more prolonged
than in the other species. The club of the antennae is subovate pointed,

frontalis, and it is only by exaj .lining the antenna; that it may with cer-
tainty be separated. The reference to the genus Phlteosinus is incorrect,
as the outer part of the tunicle is divided into six joints by five transverse
sutures, precisely as in the other species of IIylesinu». The club is sub-

Any lengthy descrip'.ion would be unnecessary, as it only dilfcrs by larger
size, and by the first and third interspaces being strongly elevated and ser-
rate behind. The pubescence is shorter, and seems less dense than in P.

This genus is founded upon IIyleninn» hyntrix, a singular species from
California, of robust oval form, thickly clothed with coarse, erect hair. It
differs from PhlaoHinifi by the four joints which constitute the outer part
of the funicle of the antennic being slender, and increasing much less rap-
idly in thickness; tlie club is equally large, subovate, compressed, obtusely
rounded at tip, and the sutures are also straight. The mouth is clothed with
long, coarse hair. The prosternum is very short in front of the coxa?, which
are very narrowly separated. The first ventral segment is longer than the
second, and the third, fourth and fifth are short. The tibiic are broadly di-
lated, rounded and finely serrate at tip; the tarsi are not plainly visible in
the unique specimen in my collection, but the third joint is emarginate,
rather than bilobed.

6. D. brevicomis, n. sp.

Elongatec iindricjil, red-brown, with a few long hairs on the prothorax,
and numerous very short ones on the elytra. Head large, finely not densely
granuliitc, rugose, occiput nearly smooth, face with an interrupted longi-
tudinal in\pression, antennie with circular compressed club, sutures trans-
verse, fuuicle .'i-jointed. Prothorax at base nearly twice as wide as long,
as strongly bisinuate as in D. frontalm; very slightly narrowed towards the
tip, and slightly constric'ed ; punctures small, not dense, surface shining,
witli no trace of a dorsal line. Elytra opaque, strite indistinct, composed
of not very evident punctures ; surface finely densely granulate, becoming
punctulate on the declivity ; in other respects it resembles the otlier species
of the genus. Length 4.2 mm. ; .17 inch.

One specimen ; Middle California. Intermediate in form of prothorax
between tlie next and the foregoing species, but strikingly different from
both by the sculpture and pubescence of the elytra.

7. D. frontalis Zimm., Tr. Am. Ent. Soc. 1808, 149 ; (synon. excl).
Lake Superior to Georgia. The head is channeled and marked with

approximate frontal tubercles ; the occiput is finely punctulate, the front
roughly punctured as usual. The interspaces of the declivity of tlie elytra
are finely asperate, and the hairs are short. The prothorax is scarcely
narrowed in front, and the base is more strongly bisinuate tlian in the other
species. Tlie clul) of the antenna; is round, strongly compressed and con-
cave on one side, as in the other species; and tlie sutures are not straight,
but curved. Length 3 mm. ; .12 inch.

The frontal channel is deeper, and the granulate punctures larger, and
denser in one sex than in the other.

BLASTOPHAGUS Eichhoff.
This genus does not i)ropevly belong to our fauna, and I mention it only
for tlie purpose of correcting the error, which I committed of describing
an accidentally introduced siJecimen of the common European 7?. plniperda
under the name llylurgm analogm, Tr. Am. Ent. Soc. 1808, Vi'Z. The
last mentioned name must therefore be erased from our list. I also com-
pared it with the Turopean //. lign'perda on theauthority of an incorrectly
named specimen which I borrowed for comparison. If the genus should
liereat\er occur In our fauna, it can be easily recognized by the outer part
of the funicle of the antunna; being divided into T^ joints, tluis making the
funicle 0 jointed, and by the club being ovate-pointed, not compressed,
transversely annulated, with the joints smooth and shining, fringed with
hairs. The beak is somewhat more distinctly developed than in Dendroc-
tonu», and the antennal grooves are wider and deeper.

Group IV. CryptiirKl.

This group consists of two genera, represented by very small species uf
elongate form, which agree with JfifliisteH In general appearance and sculp-
ture, but differ by the beak being much shorter, and the prosternuni very
short and not excavated. The genus Grypturgun has been usually associated
with the Tomic!ni, on account of the slender tarsi, but it makes a notable
exception to the other members of that tribe by the large exserted head,
and the absence of the hood-like prolongation of the pro'horax. I have,
therefore, thought it best to remove it ffom that position, and place it with
Dolurgus, as a separate group. Though dill'ering in the antcnnal club,
which is solid in Crypturgun, and annulated transversely with the lirst
joint corneous in Dolargas, these two genera are otherwise closely related,
and differ remarkably from neighboring forms by the small number of
joints in the funicle. The prothorax is ehmgateoval, rounded in front,
nearlj' truncate at base; the scutcllum is very small, not depressed, and the
basal edge of the elytra is not elevated. The elytra are elongate-cylindri-
cal, with the posterior declivity convex; the striaj are well marked, and
strongly punctured; the interspaces narrow, finely punctulate and sligiitiy
pubescent. The ventral sutures are straight and deep; the first and fifth
segments are longer than the others. The prosternuni is very short, not
excavated; the front coxa; arc. contiguous; the tihiic are dilated, and finely
serrate; the terminal spur is very small; the tarsi are slender, wiih the
third joint not dilated.

more strongly serrate, and are armed with a strong apical spnr ; the tarsi
arc rather short, and the third joint is more or less dilated, bilohed or
emarginate. The ventral sutures are straight and deep ; first and fifth
segments longer than the others. The head isexserted and prominent, the
boak short and stout, with oblique deep grooves, which unite in the gular
space, forming a transverse impression ; the eyes are transverse, not very
finely granulated. Antenna; with 7-jointed funicle and oval annulated
club, which is not compressed, and has the basal joint large, corneous and

Eichhoff gives Carolina as the locality ; Chapuis mentions Norfolk

Perhaps the specimen came from Norfolk, Virginia, instead of Norfolk

has priority by a few weeks.

HYLURGKJPS n. g.

I have separated as a distinct genus the species referred to Erichson's
secvind division, having the third tarsal joint broader and bilobed, and the
mesosternum protuberant. They are quite different in form from true
Hylastes, and resemble Deniroctonin, the prothorax b 'ing m )re narrowed
forwards, and more finely and densely punctured. The basal margin of
the elytra is so acutely defined in //. granulatu^ and pinifex that I should
place them near Ifi/lurgtm, but for the scutellum, which is not depressed;
and for the decider antenna! grooves, which remove them from the group
of Hylurgi. The front tibiip are less coarsely serrate than in 7lj/lasteit.

The species may be t'lus distinguished :

Prosternal ridges acute ; front transversely impressed. 9^

The prosternivl sutures are entirely obliterated, as is also the short suture
behind the posterior point of the prosternum.so that the under surface con-
sists of but one piece. The coxal cavities are rounded, and narrowly sep-
arated.

Mesosternum flat, triangular behind, with the jKiint rounded, and sepa-
rating the middle coxse; cavities rounded, epimera transverse, oblique, not
attaining the coxffi.

Metasternum long, side pieces narrow, or moderate in width, wider in
front, with the outer angle prolonged forwards; in many genera there is a
transverse impression in fhmt, simulating a suture.

Elytra conjointly rounded behind, and forming a small suturnl fold,
which fits into a deep emargination of the pygidium ; fold of the inner sur-
face acute, not prolonged much behind the middle. Epipleune distinct.
The striie are ten in number, with a short scutellar one as in Carabida;
this scutellar stria is usually about one-fourth the length of the elytra, and
does not connect itself with the sutural stria.

Abdomen with five free, and sometimes nearly equal ventral segments;
sutures straight; intercoxal process triangular, acute or rounded in front;
dorsal segment membranous, except the pygidium, which is corneous, de-
clivous and exposed ; no .inal segment in the (^.

Anterior coxte narrowly separated, globose; middle coxae moderately sep-
arated, rounded; hind coxte transverse, not prominent, never very widely
separated.

Legs slender, front pair sometimes elongated in (^; tibias truncate at tip,
without spurs or hooks.

Tarsi brush like beneath, 4-jointed; .second joint triangular, emarginate;
third joint bilobed, sometimes large, sometimes small; fourth joint slender
with divergent claws, which are either simple or toothed.

Our genera represent four tribes:

Antennie inserted at the sides of the beak;

Prothoracic ridge not basal tropiderisTi.

Elytra striate as usual ARiKOCERINI.

Elytra not striate XENORCHESTINI.

Tribe I. tropiderini.

The genera of thip '-ibe are sufficiently distinguished by the position and
form of the prothoracic ridge, whicli is remote from the base, more or less
sinuous, and flexed obliquely at the sides. The antennie are situated under
the lateral edge of the beak, which is sometimes flattened and expanded so
that the antennal cavities are partially covered.

This is a narrow species, with the base of the i)rothorax truncate; there
is a trace of a second transverse raised line l)etween the base and the ante-
basal ridge ; the latter is situated about one-fifth from the base, slightly
sinuate, and forming an obtuse angle at tlie middle; fiexcd obliquely for-
wards on the side, where a distinct latenxl angle is formed behind the middle.
The pubescence is yellowish brown, mixed with pale gray, and does not
exhibit any distinct pattern. Length 6.8-10 mm.; .27-.40 inch.

Group. II. Tropidcrea.

The sides of the beak in the insects of this group are dilated over the
antennal cavities, which are therefore not visible from al)ove. The form
of the antebasal ridge difters in each genus, and in conjunction with the
antennal club and tarsal claws affords easy characters for distinguisliing the
genera. The eyes are entire, either rounded or oblique.

EURYMYOTER n. g.

The well-known species upon which this genus is established, represents
in our fauna the European Plnfi/rJiinui*, but differs by the beak being
narrower than the licad and strongly dilated at the tip ; it is uneven above,
with three wide grooves and two ridges, extending as far as between the
antenna', where they end, leaving the dilated part of the beak flat ; the
sides are extended over the antennal cavities, which are small and visilde
only from the sides and beneath. The mandibles are flat, acute, and

I have established this genus uix)n a snuvll Canadian species remarkable
by the se.xual differences The form Is as slender as In Tropidere»; the beak
Is longer than the head, narrower at the bas*, slightly dilated at the tip; In
the male It Is furnished with a very high crest, gradually fading out In
front; In the 9 cnly an obsolete carina Is seen. The antenna' In the 9 ex-
tend to the base of the elytra, and are just as In Tropideres, except that the
second joint is thinner; joints 9-11 form an oval, compressed club. In the
cf the antennoe are as hmg as the body; .joints 3-8 elongated, and a little
thickened at tip ; 0-11 flattened, forming ii loose club. Tlie prothorax as
in Tropideren, but not tuberculate at the sides; transverse ridge remote
from the base, feebly curved, and subsinuate; flexed obliquely forward at
the sides. Eyes rounded, lateral, jjromluent. finely granulated. Tarsi
more slender than usual; third joint not as wide as the second; claws
appendiculate rather than toothed. Mentum with the lobes wide, nar-
rowly rounded at tip; ligula large and coraceous, filling up the einargi-
na'lon of the mentum more than In the preceding genera, (somewhat as in
certain Lebiini).

Group III. HormiMl

The genera upon which I have founded this group, seem sufliciently
distinct from the other Corrhecerides of Lacordaire to be separated from
them. I would define it by the following characters:

Beak not dilated at the sides over the antennal cavities. Eyes emargi-
nate, not finely granulated. Prothoracic ridge antebasal, oirved or ob-
tusely angulate backwards at the middle, flexed obliquely forward at the
sides. Tarsi with the first joint long; second triangular, scarcely emarglnatc;

HORMISOUS Wollaston.

In this genus the form is cylindrical and less slender than in Tropideren.
The bci :;i is broad and flat, not longer tlian the head, with the antennal
cavities lateral, not covered by the sides. Ej'es rather large, less finely
granulated, oblique, feebly emargiiuvte; antenna' alike in both sexcs.hardly
extending to the base of the prothorax, club oval, apparently solid. Pro-
thorax scarcely longer than wide, gradually narrowed in front; more rap-
idly narrowed behind the transverse carina, which is slightly oblique, par-
allel with the base, and ends each side in a lateral cusp.

1. H. Ba'*ator, n. sp.

Brownish black, mottled with spots and bands of cinereous pubescence;
prothorax densely and finely punctured; elytra with rows of large and deep
punctures, about t\\ ice as long as 'he prothorax. Length 1.2-1.0 mm. ; .05
-.07 inch.

Middle and Western States, not rare; I have adopted the specific name
with which it is labeled in the collection of the iate Dr. Zimmermann.
There are few jirominent characters in this singular little insect, except such
as are of generic value. It agrees with the Galipagoan //. vnriegatus in
having the transverse ridge of the prothorax broadly angulated at the
middle, but the latter differs, according to description, in color, and in
liaving the elytra indistinctlj' punctato-striate. The specimens vary greatly
in appearance, according as the pubescence is more or less abraded. In the
best preserved individual, the prothorax is mottled, and the elytra also, but
the mcttlings of the latter are arranged so that a subscutellar sjjace on eafh
elytron, and a broad, post -medial band not reaching the margin, are left
free from cinereous spots. The posterior transverse carina of the prothorax
Is slightly oblique, forming a very obtuse angle backwards on the median
line, and projects at the side as a small, sharp cusp.

TOXOTROPIS n. g.

This genus is closely related to Hormtscus, and in fact on^y differs from
it by the antennal club which is elongate-oval, compressed, and composed
of three distinct joints equal in length. The eyes are rather finely granu-
lated, and only feebly emarginate; the antennal cavities are small and
rounded. The antebasal ridge is regularly curved in an arc of a circle, for

1. T. pusillus, n. sp.

Of the same size, form and color as HormincuH mltator, brown, varied
with j)atclic.s of line white jmbescence; eyes larger and more i)rominent;
pr.)lhorax more finely punctured. Elytra with striiu of rather large punc
tures; interspaces even. Length 1.2 mm.; .05 inch.

Tampa, Florida, one specimen, Mr. E. A. Schwarz.

2. T. approximatus, n. sp.

Of the same form, color and sculpture as T. pusilhiit, but the antebasal
ridge is less carved, and therefore is more parallel with, and nearer to the
base than in that species. The hind angles near the base are therefore less
prominent, and the body is somewhat stouter. Length 1.5 nun. ; .00 inch.

One specimen, San Diego, Cal. ; Mr. G. R. Crotch.

QONOPS n. g.

This genus is also related to the two preceding, but differs from Ilormis-
ciwbythe antennal club compressed, and composed of three joints equal
in length; the antennal cavities are small, and the eyes are deeply emargi-
nate and rather finely granulated. It dift'ers fron^. both by the claws being
clet\ almost to the base, with the inner portions converging as in Anthono-
mu8. It also ditfers from all the other genera in our fauna by the middle
and hind tibiie being armed with a small mucro or spine at the inner side
of the tip. The form is a little stouter than in llormucus; the antebasal
ridge of the prothorax is curved in the arc of a circle; towards the sides it
Is nearly transverse, and ia not flexed forwards.

1. Or. flssunfifuis, n. sp.

Oblong, rather robust, brown, mottled with small spots of yellowish
gray pubescence. Head and prothorax opaque, very densely and finely
punctured; the latter a little wider than long, narrowed from the end of
the ridge forwards, but scarcely rounded on the sides; rapidly and con-
cavely narrowed behind the ridge, the end of which forms an acute lateral
angle. Elytra not wider than the widest part of the protharax, convex;
stria; composed of moderate sized punctures, int(;rspaces very finely punc-
♦ ulate. Length 2.5 mm. ; .10 inch.

Three specimens from Big Trees, California; sent ">y Mr. James Behrens
to Dr. Iloin.

Tribe II. bahitropixi.

The only ch.inici?rs of a general kind which can be given to distinguish
this from the other tilbeS; are that the antcniue are inserted under the
sides of ih( beak, and that the prothoracic ridge is quite basal, causing the
surface behind it to become perpendicular ; it consequently attains the
hind angles, and is there flexed forwards, not obliquely and at an obtuse
angle, but rectangularly. As a farther consequence of this arrangement,
the basal margin of the elytra is acute.

gin of the prothorax extends to about the middle ; the base is slightly bisin-

uate, and the lower basal margin is very well defined, so that when the

prothorax is deflexed, it might be supposed that the transverse ridge was

not absolutely basal. The same is the case, though to a less extent, in the

genera of the preceding group. The front coxa? are contiguous, and the

mentum is but feebly emarginate in our species ; the buccal fissures are

ritherwidc.

Our two species differ by the color of the pubescence :
Brown, with the sides of the prothorax, and large clytral
spot concave backwards, yellowish-gray, rest of the sur-
face mottled 1 . lunatus.

Group III. Rrachy«arsl.

In this group the beak is gradually narrowed from the eyes forwards, so
as to become trapezoidal in form ; the antennal cavities extend to the eyes,
which are coarsely granulated and emarginate in front. The first and
second joints of the antennie are stout, the second a little longer, 3-S
shorter, gradually a little wider ; 9-11 nuich wider, forming an oval com-
pressed sensitive club. Prothorax rounded in front, overhanging the head,
basal ridges flexed rectangularly at the angles, but extending only a very
aJiort distance along the sides; inferior basal margin acute. Elytra with even
and eijual interspaces. Tarsi with the first joint scarcely longer than the
second, which is triangular and emarginate ; third deeply bilobed, not nar-
rower than the second, claws toothed near the tip, so as to appear cleft.
Mentum deeply emarginate with lobes, rounded at tip ; gala transversely
impressed.

Our species represent two genera, one of which has not been previously
recognized.

This genus contains the type of Geotfnjy's genus AnthribuK ; but in con-
sequence of his only semi-recognition of the binominal Linnanin nonien-
cluture, of a definition properly accompanied by a specific name, indica.
ting the object described, was delayed until 1799. The generic mime tlius
proposed bj' him (17G4), was appropriated by Olivier (1789), and by La-
trt'ille and Fabricius suljsequently, and applied to an assemblage of species
now divided into several genera. Schoiiherr afterwards divided tliis as-
semblage of spi'cies, and gave the name Brachytursux to the genus here
treated of. I cannot, therefore, advise tl>c restoration of the name Anthri-
bufi, with the authority Geodroy, to this genus, even though it ho. sanc-
tioned by tlie authority of the Munich Catalogue, and the Check List of

Massachusetts to Louisiana. This species differs in form from the Braehy-
tarsi by having the sides of the i)rothorax broadly rounded, and the elytra
slightly narrowed and rounded near the base. The body is rather elongate,
proportioned nearly as in B. van'egatux, dark brown, densely clothed with
brown and silvery gray pubescence; the head is fla', and the rostrum
slightly narrowed at the insertion of the antenna;; the latter are testaceous,
wilh the club fuscous; prothorax longer than wide, graduallj' narrowed in
front and rounded on the sides, tip rounded; base broadly rounded,
transverse ridge not continued along the sides; hind angles obtuse, slightly
rounded. Elytra oval, convex, a little wider than the base of the pro; borax;

scarcely attain the base of the prothorax.

Tribe IIL AR^KOCcnixi.

But two genera of this tribe have occurred in our fauna ; they are of
small size, and are easily known by the antennte being inserted in small
foveiE upon the upper surface of the beak. The transverse carina of the
prothorax as in the preceding tribe is basal, suddenly flexed, forming a
right angle, and extended a short distance along the sides ; the antenniu
are slender, and the last three joints form a loose club. The elytra are
regu'arly striate as in all the preceding tribes and groups of the family.

Th(! si)eciea of this family are small, and have a peculiar and easily re-
cognized appearance. Lacordairc has placed them, as a tribe near his Atte-
Idhides, with whicli, however, as will be seen by the foregoing description,
they have but little resemblance, or affinity.

Lacordaire describes them as apterous ; in all the species I have examined
the wings are (piite well develo;'ed. I also find that in many of our species
the claws are toothed or api)endiculate, while in a few they are simple, and
I have therefore attempted to group them in mj' collection upon those char-
acters, the position of the antenniu, and the relative leng' f the flrst and
second joints of those organs.

The s;:ecies are numerous, and many are yet und. d. It seems

hardly worth while to affix names to them, until they have been collected,
with referenci! to the i)lanls wliich they infest. I will, therefore, on the
present occasion give only the bibliography of the described species, in al-
phabetical order, with such notes on their habits, as I have been able to
obtain.

Topeka, Kansa.^ ; Mr. E A. Popenoc. I have seen two specimens of this
very i)retty species, one of which has been kindly placed in njy collection,
ft dillers from P. ciniiplitK not only by the color but by the first joint of the
funicle being large and the seccjud not longer than the following; the funicle
is also thicker and the club larger than in that species.

The scales in this species are deeply cleft almost to the base. Since the
printing of that part of this memoir which relates to the present genus, I
have examined more closely the scales of the different species i;i our fauna
with the following result :

A. Scales thick, truncate, or very feebly cmarginatc at tip, with the an-
gles not prominent.

a. Scales scarcely striate, nearly uniform ; compim, cximins.

b. Scales dislinctlj'^ striate, with longer narrow ones intcnnixed, which
are the bristles of the elytml interspaces. These bristles are obtuse in qiidd-
ricolliK, but acute in the European rinniris.

B. Scales elongate, striate, truncate and slightly emargina'e at tip,
opi7nu8.

C. Scales elongate, striate, acutely and deeply emarginateat tip, with the

less deeply euiarginate. The bristles are similarly striate, but longer and
acute.

D. Scales narrow, cleft, with slender, acute lobes ; bristles longer, acute
and simple.

a. Scales cleft for two-thirds the length, piihicolUx.

b. Scales cleft nearly to the base ; elun/afm, Custor.

It is apparent therefore, that valuable characters maybe fornd for the
recognition of the species in this ditflcult genus, by the study of the f<jrm
of the scales.

This species has a slender form, and is clothed with ratli'.T coarse grayish
pubescence, with a stripe of paler color at the sid;'3of the [)rotiiorux and ely-
tra. The beak is cylindrical, rather stout, about twice as long as the head,
punctured, carinate for one-half its length without fovea between the an-
tennffi ; frontal groove short, deep, antenna; inserted one-fourth from the
tip, black ; funicle stout, first joint but little longer than the second, which
is scarcely longer than the third. Prothorax one-third longer than wide,
gradually narrowed from the base forwards, sides straight ; punctures large,
shallow, approximate, disc longitudinally broadly and somewhat deeply
excavated towards the base ; medial angle produced, obtuse!y rounded.
Scutellum not visible. Elytra a little wider than the piothorax, sides
rounded near the base, then converging behind, tips separately slightly
prolonged, and acuminate ; striie composed of distant punctures, mos.ly
concealed by the coarse pubescence. Length 7.6 mm.; M.) inch. *

Arizona and Lower California. This species is as slender as L. rubeUiiii,
but the tips of the elytm are only slightly prolonged, and the other char-
acters are quite ditterent.

I neglected to mention that the third joint of the tarsi in L. ph uridin and
texan'is is much less broadly dilated, and the lobes are less obtusely rounded
than in the species of division C. The lobes therefore envelop more closely
the base of the fourth joint, thus shawing a transition from Clcotom to Lix-
us, which would probably warrant the separation of these species as a dis-
tinct genus.

The first part of the table might be modified to indicate this ditfcrcnce,
which is better than the characters I have used on p. 154.

tween the antennsB, and a deep frontal fovea ; between these points it is
distinctly carinate ; thinly pubescent, with suberect liair, nearly naked at
the tip. Head punctulate, with scsictered larger punctures which extend
upon the basal part of the beak ; antennoe inserted one-third from the tip,
black, fuuicle as in L. pleimtUa. Prothorax scarcely longer than wide,
narrowed from the base forward and rounded at the sides, convex, bisinu-
ate at base, medial lobe broad, prolonged, obtusely angulated; disc densely
punctulate, with large shallow punctures not densely placed ; vaguely and
broadly longitudinally impressed from the middle to the base : there is a
broad lateral stripe, and two indistinct dorsal ones of denser gray hair.
Scutellum small, but distinct. Elytra separately rounded at tlie base, the
curvature being continued to the sides, so that the humeral angles are in-
distinct, sides parallel, rounded behind ; tips separately acutely rounded,
with a small tuft of hair which gives them the appearance of being sub-
acuminate ; broadly impressed near the base, which causes the basal margin
to become obtusely elevated ; striaj composed of distant round punctures ;
sides with a broad stripe of denser pubescence. Beneath clothed with gray
pubescence, coarsely and sparsely punctured. Leng.h 10 mm.; .40 incli.

Enterprise, Florida, one specimen ; Messrs. Hubbard and Scliwarz.
Easily known by the small deep prothoracic excavation and the acute
scutellar lobe.

Another specimen from Florida agrees in form and sculpture, but differs
by the beak more finely punctured, or rather puiictulate, shining, and very
slightly pubescent. The basal excavation of the prothorax is larger, less
deep and vaguely channeled ; the medial angle is equally acute and i>ro-
longed. The elytra arc separately but more obtusely rounded at tip. I
think this is the 9 corresponding to the (^ above described.

than third. Length 2.4 mm.; .10 inch.

Enterprise, Florida ; one specimen, Mr E. A. Schwarz. The scales have
been removed by abrasion, and only a few remain near the base of the ely-
tra, and the sides and base of the prothorax. Tlie apical constriction of the
prothorax does not continvie across the prosternum as in tiie otiier species,
and as in all Gentrinus known to me, but disappears in the apical margin,
thus leaving the front part of the prosternum flat. This should probably
be considered a generic ditference, but I am unwilling to separate it witli-
out liaving better preserved specimens for study. The claws seem to be
very small, bi 'ardly connate at base.

Enterprise, Florida; one specimen, Mr. E. A. Schwarz.

4. Barilepton quadricoUe, n. sp.

Very narrow, linear, black, clothed with elongate small whitish scales,
beak less stout, punctured at base, smooth at tip. I'rothorax as long as
wide, sides parallel behind, suddenly rounded and narrowed in front of
the middle ; strongly and rather densidy punctured ; dorsal line smooth,
distinct, scales more dense at the sides. Elytra suddenly a little wider
than the base of the prothorax ; striie narrow, deep, impuiictured, inter-
spaces finely punctured, beneath strongly jiunctured, thinly clothed with
small whitish scales. Length B.2 mm.; .18 incli.

Nebraska, one specimen ; given me by Mr. Ulke. I confounded this
species with B. fiUforme, which it resembles in the form of the prothorax,
but differs by the stronger pvmctuation and by the elytra being distinctly
wider than the prothorax just behind the base ; the scales are also whiter
and larger, and the elytral strite are deeper.

These four species may therefore be distinguislied as follows :

Body very narrow, filiform, elytra not wider at base
than the prothorax, which is densely but not deeply
punctured, scales very small, gray, denser at the
sides of prothorax and elytm V filiforme.

Body very narrow, prothorax strongly and densely
punctured, suddenly narrowed in front, scales
of elytra oval, whitish, not very small 4. quadrloolle.

Body linear, but less narrow, prothonix densely, less
coarsely punctured ; elytra a little wider than tlie
protliorax at base, scales very small, rounded, yellow-
gray 2. lineare.

Body as in Ji/K'arf, but the elytra are more conspicuously
wider near the base, and the scales arc elongate,
white, and form stripes ; prothorax more coarsely
punctured 3. oribriooUe.

TRIOHISOHIUS n. g.

This genus is founded upon one species, which agrees with Sphenoph-
orui, except in the following characters :

The inner side of the front and middle coxae and the middle of the meta-
•tcrnum and the first and second ventral segmentsare clothed with longhair;
the thighs beneath, and the tibiue on the inner side are fringed with long
hair ; the genital segment of the ^ projects (as in llhyni'hophorus) and is
fringed with hair at the tip. The third joint of all the tarsi isslender, notat
cU dilated <^r eniarginate, glabrous beneath, fringed at the sides, and quite
as long as the secoad joint, which is equal to the first.

The ppothurax is uniformly punctured, without impressions, but with a
narrov smooth dorsal line, and the elytral stria; are deep and crenate ; the
inierspacts are t;ven, and scarcely punctulate.

1. T. crenatus, n. sp.

Black, subopaque. Beak scarcely more than half the length of the pro-
thorax, .slender, slightly curved, finely punctured, wiih a very fine longi-
tudinal impressed line near the base, which terminates in a small, frontal
fovea. Prothorax nearly one half wider than long, narrowed in front of
the middle, and ro"nded on the sides, tubularly constricted near the tip ;
base neiniy truncate 'vitl> the edge acute, and sparsely fringed with yeUow
hairs ; disc rather densely but not coarsely punctured, more coarsely towards
the base, each side of the medial line, where it is feebly impressed ; dorsal
line narrow, very distinct, slightly elevated near the base. Elytra at base
a little wider than the prothorax, basal angles slightly projecting forwards ;
Btria' d(!ep, crenate, interspaces nearly Hat, scarcely perceptib'y punctulate ;
humeri reddish ; i>ygidium with the hind part strongly, rather densely
punctured ; apex (^) declivous, smooth, concave ; genital plate prominent,
smooth. Beneath shining, strongly but not densely punctured ; punctures
larger on the meta,sternum ; side pieces narrow, parallel ; prosternum very
narrow between the coxie. Length 8.8 mm. ; .35 inch.

I would refer to this genus, which is fully described by Mr. WoUaston
in Trans. Ent. Soc, London, 18(>8, 401, a small slender reddish-brown
opaque Cossonide, Ihiuiy clothed with coarse hair.

It has all the characlir:; given in the description, except that the hairs
are not long, and the antennic are not very pilose and the surface not
shining. The more imi)ortant ones may be recjipitulated as follows :

LeConte.]

APPENDIX.

427

Body narrow, linear, rather flat, sparsely pubescent. Beak parallel,
cylindrical, separated from the front by a distinct impression ; eyes rather
large, transverse, coarsely granulated, situated on the sides and under sur-
face of the head, not visible from above. Antenna; inserted about the mid-
dle of the beak, short and stout, scape attaining the eyes ; funicle first joint
large, 2-7 very short, closely connected, club small, oval, shining, sparsely
hairy, annulated only at the tip. Metasternum rather long ; front coxae
widely separated, the others still more distant ; tibite with the terminal
hook very large ; tarsi rather short, third joint but little wider, somewhat
bilobed.

The genus has thus far occurred only in Jlalabar, and rh<didonotu»,
which immediately follows it, is found in Borneo. It appears, therefore,
to be a third instance of that remarkable distribution which I have pre-
viously mentioned in the Heteromerous genera Othniua and hchalia.

1. H. errans n. sp.

Very elongate, reddish-brown, nearly opacjue, thinly clothed with coarse
yellowish hair. Beak a little shorter than the prothora.\, rugosely punc-
tured, transversely impressed at the ba^e. Head finely punctured. Pro-
thnrax more than one-half longer than wide ; widest near the base, sides
suddenly rounded behind the widest jiart, but gradually obliquely nar-
rowed in front and nearly stmight ; sliglitly constricted near the tip ;
disc rather flat, densely and coarsely punctured, without impnssions or
dorsal line. Elytra not wider than the wideet part of the prolhorax, trun
cate at base, scutellum not visible, sides paniUei, rounded at tip ; striae
deep and l)road, punctures large, quadrate, interspaces very narrow. Body
beneath very coarsely punctured , punctures of ventral segments not
smaller. Length 2 mm. ; .08 inch.

District of Columbia ; collected by Mr. Ulke. I owe a specimen of this
interesting species to tlio kindness of Dr. Horn.

4. Barynotus granulatus Say, Cure. 12 ; Lcc , ed. i, 273.
Brown, thorax obtusely granulated, with a pale vitta.

Inhabits Indiana. Body dull brown, with short raised hairs ; head im-
pressed between the eyes. Thorax with very obtuse granalations, a longi-
tudinal, slender, impressed dorsal line in a dull yellowish viita. Elytra
a little elevated on tue basal edge ; striie concave, much dilated, punctured ;
punctures wide, not very deeply impressed, interstitial lines not sc wide as
the strise, with hairs ; suture a little pale. Length about one-fourth of an

Tlie surface of the thorax exhibits the appearance of obtuse little elevated
granulations, and the profile view shows irregular punctures or interrupted
rugffi.

5. Byrsopages oarinatus Motsch. , Schrcnk's Ileisen, Amur. Ins. 108.
Closely allied to Ji. venh kosus Motsch., ibid., and distinguished only by

the gray fasciculated pubescence which clothes the elytra, causing them to
appear spotted ; by very slightly elevated ridges, which s'^em to replace the
striiB of tlie elytra, and by the head more strongly punctured ; the latter is
reddish, as are also the antcnntc and legs ; the teeth and the spines at the
tip of the tibaj are longer and more distinct ; the under surface »f the body
redder and less glabrous ; punctuation not dense but very obvious, and
pubescence more developed. Length 4 lines.

Black, covered with minute cinereous liairs, thorax impressed. Elytra,
region of the scutel and middle of the base indented.

Inhabits United States. Body black, covered with short minute robust
)' curved hairs, punctured- Antennic rufous, club dusky. Thorax a
little convex each side, behind the middle of the side rectilinear; a little
contracted before with an indented line above, more profound near the
base, with dilated, confluent, slightly impressed punctures, not deeply
sinua'ed at base, with regular series of punctures. Elytra, region of the
scutel indented; abdomjn dull fulvous behind. Length nearly seven-
twentieths of an inch.

[This species is said to occur on the lower Mississippi and in the Atlantic
States. I have not identified it, nor was it known to Gyllenhal, who
merely cites Say. ]

my re(iue»l by Mr. H. Plckmiin Miiiiii, of CiinibrUlge, Muss.

It will be un iiiviiUmble addition to this volume, for ail who desire to
study the habits of these insects: a prerequisite to any rational enquiry
into th(! means to be adopted for the supijression of the noxious species.
Such a study has been heretofore almost impracticable in this country, in
consequence of the large number of undescribed si)ecies, and the scattering
of the descriptions of those which have been named in a multitude of vol-
umes, many of which can only be obtained with much labor anil great cost.
For the proi)er use of the tables, certain explanations arc necessary.

I. The subjects mentioned in the articles cited are indicated as follows :
b. benefits. d. description. /. food.

h. habits. t. injuries. /. localities.

r. remedies. «. seasons. t. transformations.
