V Entomoldgjcal Sf^anch ^ \ DEPARTMENT OF ^g^ AO«ICULTU«E 1,^ OTTAWA. :ii3 i> J b PREFACE, 1 The study of the Hynien(){)tera of our country has not kept pace with some of the other orders from the want of an introductory work in our own language. Westwood's invahiable " Introduction to the Modern Classification of Insects," while ])artly supplying the want, is insufficient, and at the present expensive and difficult to obtain. The want is especially felt by those who have not access to large scientific libraries, and many are discouraged i'nmi attempting the study by the difficulties and expense of acquiring the necessary litera- ture, with the added difficulties of the foreign languages. The writer has been frequently appealed to and requested to indi- cate such books as will enable a beginner to separate even the fami- lies and geiMjra. The impossibility of obtaining any works in the English language, and the almost equally hopeless chance of deter- mining the species, have doubtless deterred many from aiding in the development of the study of {irobably the most interesting order of insects. Other extensive orders, as the Coleoptera and Lepidoptera, have nunjerous votaries from the aids furnished by elementary works on cla.ssification, and until similar assistance is given, very little progress can be expected in the study of the Hymenoptera, notwithstanding the fact that there is no order of insects more extensive and varied in structure, and certainly none more interesting in the habits of its members. Students are so few, in fact, that the greater part of the material collected together in the larger families has been very im- perfectly studied, and our knowledge of the characters is very in- complete, so that years of careful study will be necessary before a classification can be produced that will be approximately complete. As a step in that direction, however, it has been suggested that the publication of a series of syno]»tic tables giving the leading charac- ters, as for as known, of the families and genera, would })rove a great aid to the student and j)ossibly induce many to collect and study these interesting creatures. IV PREFACE. With the ho|)e that .such may prove to be the case, the following tables have l)een compiled from the writings of Wesmael, Holmgren, Westwood, Thomson, Taschenberg, Norton, Marshall, Andre, Mayr, Saunders, Howard, Cau)eron, Ashmead and others. Little or nothing original in the arrangement is claimed by the compiler. The char- acter' given in many cases, especially in the Tchneumonidse, are very unsatisfactory, otlen difficult to describe intelligibly, and yet they are about the best that can be offered with our present incomplete knowledge. Doubtless, after more careful study has been made, new and more reliable characters will be discovered, that will make the divisions more easy, simple and correct. As a rule, only such genera as have been found to occur within our faunal limits are characterized in the synoptic tables given herein, but in some families, e. g. Ichneumon idie, Braconidae, Chalcididie and Proctotrupidoe (our material of which has been so little studied), some of the European genera, not yet recognizetl with us, but prob- sd)ly will be, are added, and are indicated by an asterisk preceding the name. As an aid to the student, the synopsis is followed by an approxi- mately com{)lete catalogue of the species that have been described sis inhabiting our fauna, closing with a list of works and papers having reference to our Hymenoptera. In conclusion, the compiler desires to express his thanks to the Rev. T. A. Marshall and Messrs. L. O. Howard, W. H. Ashmead and George B. Cresson, who have most kindly aided in the prepara- ti VamWy Phi/n, if hidw 11«, 'JMO Family J/('mex»/if ....... 11J», 2H2 Family J/e///»/V/(e 11!>, 2«;i Family Pemphredonhhr 120, 2«3 Family CrnbronidxB 121, 2^4 DiPLOPTERYGA 12o Family Mnmrid(F .

The eyes (a) are generally large and lateral, naked, rarely pilose, occasionally occupying in the males of certain groups, tiie greatest portion of the head ; they vary much in form and size, being sometimes reniform, ovate or circular, sometimes small or even minute and very rarely wanting ; they are accompanied by three small simple ocelli (e) placed either in a tri- angle or 1 a straight or curved line upcm the vertex, but in the apterous females of certain genera of Heterogyna and Mutillidae these ocelli are entirely wanting, while in some of the Larridae and Sapygidte, the j)03- terior pair is distorted and subobsolete ; oc- casionally, as in Ophion, they are unusually large and prominent. The dypeuH (b) is placed on the front, beneath the insertion of the antenna; (f) and is variously formed, usually shield-like, but often narrow and transverse, and sometimes produced into va- p- J rious curious shapes, the apical margin being a, eyes ; b, ciypeus ; c, lab- often denticulate; in the Dorylida; it is very rum;d, mandibles; e, ocelli; niiuute or obsolete. The mandible'* or jaws f, insertion of antennte. , ,. . .11 ^i ^i 1 1 (d) are mserted beneath tlie eyes and on each side of the mouth opening, rarely contiguous at their base ; they vary much in form and size, and are simple or more or less dentate on their inner margin and apex, sometimes they are long and sickle- shaped. The Inbrum, or roof of the mouth (c), is variously shaped, transverse, ovate, cuneiform, or rostriform, and is situate in front of the clyi)eus and between the mand'bles, and is often concealed by them. The inner parts of the mouth, which reach the fullest de- velopment in the Bees, are, in short, composed of a pair of long membranous or coriaceous maxillae, each provided with a palpus varying in the number of joints from 1-6, and a lower lip or tongue, having a basal mentuni from which proceeds the labium and its GENERAL CHARACTERS. 3 palpi with from 1-4 joints, ai;d occasionally with slender filaments or paraglossae, which vary in length according to the size of the maxillae. The Antenn.t- (fig. 2) vaiy greatly in structure in the various groups, those of the males are generally longer and more developed than in the females, and often '^uriously formed ; tiiey are inserted (fig. 1, f ) usually on the middle of the face, sometimes nmch lower down close to the clypeus, and rarely far apart. In most of the groups having one-jointed trochanters, these organs are usually filiform and simple, and D-, almost uniforndy composed of 16 joints in the males and 12 in the females ; while in the ditrocha groups they vary greatly in the number of joints, from 3 to 60, and '^' "■ also in form, being setaceous, filiform, mo- ' ^'^^^^ ' > se nilifi)rm, clavate, fusiform, furcate, pectinate and flabellate, rarely ciliate with long hairs ; they are sometimes elbowed, the scape (a) simietimes very long, usually short, ovate or oblong-ovate, rarely strongly dilated and shield-like, the flagellnm ( b) being generally much longer than the scape, from which it is usually separated by a ring-joint or pedicel, which in the Chalcidid* and Proctotrupidte is often composed of two or three minute joints. The Thorax (fig. 3, upper portion) generally forms a compact, oval, agglutinate ma.«s, sometimes elongate and subcompressed, higher than wide, as a rule broader than high ; in some of the apterous fornjs of Mutillidic the segments are soldered together, and in most of the female and worker ants it is elongated and often more or less strangulated and nodose, and sometimes spinose. It is composed of many pieces, but for the purposes of this synopsis the divisions shown in the cut will suffice. The prothorax (a), to which the anterior legs are attached, is generally of small size and the portion visible from above is usually termed the collar ; the posterior margin is often arched, occjisionally angular and sometimes extending back to the tegidce (f ) as represented in the figure, thus forming the front of the upper portion of the thorax ; it is sometimes elongated into a neck as in some of the Uroceritla;, Stephanida;, etc., while in certain genera of the Pompilida; it is almost quadrate and as large or larger than the raesothorax. The mesothorax (b) is usually larger and more extensively developed than either the prothorax or metathorax, and is either flattened or more or less convex, sometimes trilobed in fnmt. GENERA OF HYMENOPTERA. Fig. 3. a, prothorax ; b, mesotborax ; c, scutellum ; d, postscutellum ; e, meta- thorax ; f, tegulae ; g, parapsidal grooves. the impressed lines between the lobes, termed parapsidnl grooves or furrows (g), are frequently used in characterizi .^ certain genera among the smaller Parasitica. The scutellum (c) is generally flat, or aim- pi) convex, sometimes square, or scu- tatiform, or bituberculate, und occa- sionally armed with spines or teeth ; in the Ichneumonidie it is sometimes pyramidal and often of difi'erent color from the rest of the thorax. The }wst- sciitellum (d) is almost always narrow and inconspicuous, rarely armed with a spine as in Oxyhelus. The metatho- rax (e) is variously formed, generally short and rounded posteriorly, some- times elongate and truncate behind, and occasionally bituberculate or bi- spinose ; on each side towards the base is placed a small spiracle, which is either round, oval or linear; the Tenthredinidaj often exhibit two very small white s]K)ts (cenchri) at the sides of the extreme basal portion ; in the Ichneumonida? the metathorax is often more or less distinctly areolated. The pleura or breast is the lateral portiim of the thorax beneath the wings, and is very seldom referred to in char- acterizing genera. The Wings (fig. 4, anterior ; fig. 5, posterior) are four in number, naked, membranous and horizontal ; the anterior pair generally much larger than the posterior, the extreme base of the former being pro- tected by a scaly ])late, called the tegula (fig. 3, f); they are fur- nished with veins or nervures, for the most part arranged longitudi- nally and transversely (but never forming a close net-work as in the Neuroptera), the spaces enclosed between the nervures are of various sizes and shapes and are termed celh and are fully illustrated and explained in the diagrams given below. In some families, e.g. Chal- cididae and Proctotrupidfe, the number of these veins or nervures is, however, liable to considerable reduction, the wings being almost, or even entirely destitute of them and are often more or less pubescent. In a genus of the last-named family the anterior wings are very long, consisting of a linear branch, dilated and spatulate at tip and ciliate with long hail's ; in another genus they are notched at the extremity. GENERAL CHAKACTERS. 5 During flight, the anterior and posterior wings are connected by means of a series of minute hooks, or spinulje (fig. 5, m), along the anterior margin of the posterior i)air, which catch the hinder margin of the anterior pair and thus produce one continuous surface on each side. Occasionally the wings are more or less abbreviated, or entirely wanting r apterous forms are found in the families Ichneumonidaj, Braconidse, Cynipidae, Chalcidida?, Proctotrupidae, Formicidse, and MutillidjB.

The first joint, or that by which they are attached to the body, is called the coxa (^a) and is variously shaped and rarely spined; at the extremity of the coxa and between it and the femur is a small piece, often two-jointed, called the irochmter (b), this is usually short and small, although in the ditrocha groups it varies considerably in form and length. The first long piece of the legs is called the thigh or femur (c), and following it is the tibia (d); at the extremity of the latter are (me or two movable spines called tibial spurs (e), which are, however, sometimes absent. Following the tibia is a series of joint'i, generally five in number, constituting the foot or tarsus (f ), the last joint usually bears two daws (g), either simple, toothed or cleft, and often furnished at their base within with a membranous or cushion- like appendage called puhillus, which is occa- sionally much enlarged and sometimes wanting. These parts of the legs vary greatly in the dif- ferent families, being fitted either for walking, digging or collecting pollen ; in the latter form they are furnished with more or less dense hairs, the tibia and base of tai-sus being flattened and dilated ; those formed for digging are robust and bristly or spinose. The femur is often r<)bust, and sometimes spined beneath, and in some Chalcids the posterior pair is enormously developed and denticulate beneath ; the tibia and tarsus also vary much in structure ; in some genera of Proctotru- pidae, the anterior tarsus is terminated by curious large reflexed claws which open and shut somewhat like those of a lobster, while in some of the males of the leaf-cutting bee, Megachile, it is broadly dilated and fringed w'th long hairs; these and other modifications of form are consequent upon diversity of economy. The Abdomen (figs. 7 and 8) is exceedingly variable in the num- ber of its segments, especially in the ditrocha groups, while in the Ants, Wasps and Bees, it is com])osed of seven segments in the males and six in the females. In form it varies greatly, being ovate, glo- bose, clavate, cylindrical, fusiform, sickle-shaped, knife-shaped, etc., and in some species it is sessile (fig. 7), i.e. connected with the thorax by quite or nearly its entire breadth, and in others petiolate (fig. 8), Fig. 6. a, coxa ; b, trochan- ter ; c, femur ; d, tibia ; e, tibial spurs ; f, tarsus ; g, tarsal claws. GENERAL CHARACTERS. 7 i.e. connected with the thorax hy a more or less slender [)etiole or footstalk. The terms "subsessile" and " subpetiolate" are modifica- tions of the sessile and petiolate forms and are characters not only difficult to descr'lie by word or figure, but unsatisfactory and l)erj)lexing. In the Heterogyna the petiole is either scale-like or nod(/se, otlen binodosc, and in the Tubulifera the nundier of visible abdominal segments is usually reduced to three, the remainder being modified into a slender retractile tube, which is generally concealed. The place of insertion of the abdomen is at the aj>ex of the metathorax, except in the anomalous family Evaniidie, where it is inserted on the disk or very near the bsise of that segment. In the Ichneumonidae the situation of the spiracles on each side of the first segment is fre- •juently used as a character for separating some of the subfamilies. In the females of Hymenoptera the abdomen is furnished with an instrument applied in the different groups as a saw, borer or sting, })rotected by sheaths and called the ovipositor, which is often more or less exserted, sometimes to a great length in certain genera of Ichneuraonidse. Fig 7. Fig. 8. Professor Westwood, in his " Introduction," etc., vol. ii, following oliiefly the views of Latreille, divides the Order into two Sections, viz. : Terebhantia and Aci'leata, the former having the abdomen of the females furnished with an instrument employed as a saw or borer for depositing the eggs ; and the latter having the abdomen of the females (and workers) armed with a sting connected with a poison reservoir, the antennae of the males 18-jointed, and of the females rj-jointed. The Tkuebraxtia is then divided into two subsections, the first, termed the Phytiphaga, having the abdomen sessile, hiding the base of the posterior legs, the larvae with a well developed mandibulated mouth, feeding upon vegetable matter, and containing the families Ttidhredinifhe and Uroceridoe. The second subsection, the Ento- inophaga (Pupivora Latr.), having the abdomen attached to the thorax by a portion only of its transverse diameter, the larvae with slij.ditly developed mandibulated trophi, and for the most part feeding 8 OENEKA OF HYMENOPTKRA. parasitically upon other living insects ; this subsection is subdivided into two divisions, the first of which, the Spiculifem, having the ab- domen furnished with a plurivalve oviduct and containing the fami- lies (Jtjnipiihv, Evaniidce, Ichneiimonidxe, BmconMie, Chalcididw and •P)'odoirup'uhe. The second division, termed the Tubulifera, having the extremity of the abdomen tubular and retvnctile, and furnished with a minute sting, the larvae feeding uj)on the larvae of other hy- menopvera, or upon dead or paralized insects deposited by the parents of such larvae for the support of the latter, and containing the single family ChrysididcE. The second Section — Aculeata — is divided into two subsections, viz.: Praedones (including the Heterogyna, Fossores and Diplop- teryga) having the basal joint of the posterior tarsi cylindrical, not dilated, nor formed for collecting pollen, the larvae feeding upon other insects stored up, or upon animal or vegetable fluids provided by workers, and containing the families Crabromdce, Larrid(je, Bem- becidw, Sphecidce, Seotiidce, MntHlkkc, Formicidie and VespidcB. The second subsection, the Mellifera ( Anthophila Latr.), having the basal joint of the posterior tarsi dilated and pollinigerous, the larvae feed- iiig upon honey or pollen paste deposited by the parent, or collected by workers, and containing the families Andrenidce and Apidoe. The arrangement followed in this Synopsis is similar to that pro- posed by Dr. Hartig (in Wiegmann's Archiv. 1837, No. 2), and agrees somewhat with the above, except that the two principal divi- sions are founded upon the structure of the trochanters. The following table will serve to distinguish the diflerent series : Table of Series. Trochanters two-jointed. — Hym. ditrocha. Abdomen connate with the thorax.

In the other families of this division the posterior trochanters are distinctly 2-jointed. . ; , TABLK OF FAMILU». 11 11. — Anterior wiii^H without complete or closed MiibiiiarKinnl cells 12.

Mr. Peter Cameron, in his elaborate Monograph of the Briti.-'h Phytophagous Hymeno})tera," (of which two volumes have been j)ub- lished, 1882-1884) suggests an arrangement so different from that given above, that it has been thought well U) reproduce it here, as far as it goes, as a possible aid to the student who has not access to that valiuible work. In the first place, he divides what he terms the "Phytophagous Hymenoptera (variously called Phytiphaga in allusion to their habits, * This name will have to give place to Pamphilius Latr., which was described in 1802, and therefore has priority.

Our species may be separated into two genera, distinguished by the following characters : Posterior tarsi 5-jointed in 9 (and presumably so in %) ; neck comparatively short ; abdomen subsessile, the first segment not longer than the second. NtephaiinN Jurine. Posterior tarsi S-jointed in 9. 5-jointed in % ; neck long; abdomen petiolate, the first segment long, slender, cylindrical, fully twice tlie length of the second MogiMchus Brulle. The characteristics given above of Stephanm are those of a species (cindlpes) from Wsishington Territory, the only one yet described jus occurring in our fauna and of wliich onlv the 9 i*^ known ; the form PARAHITU'A — BRACONIDiE. 68 of the neck and abdomen differs considerably from that jriven by authors of Sti-jthanus, and it is probable that our 8|)ecie8 is referable to a new j^enus. Of MeyischuA, three species have been described from Pennsyl- vania, Georgia and Texas. The 8i)ecies of this family aj)|)ear to be rare in collections. Family BRACONIDiE. This family (the Ichnenmoneti adttciti Nees) is closely relate*! to the Ichneiunonidie, and is distinguislu-d l)y the ab'^'^'v-e of the second re- current nervurc in the anterior vvinjp*, and by havinjjf the first sub- marginai cell generally, though n(»t always, separated from the first discoidal cell, and with the exception of one subfamily, the Aphidiinse, by the non-existence of a real articulation between the second and third abdominal segnjents. Sometimes these two segments are sol- dered together, without a trace of a suture between them ; when the junction is visible, it is called the suturij'orm (niieulution. In the Apbidiiniv, all the segments are loosely articulated and flexible, and consequently capable of being bent forward beneath the thorax. The following diagram of the neuration of the anterior wing of a liraconid, from which the majority of the characters for the separa- tion of the genera are taken, will serve to aid the student in locating the various cells and nervures.

The females are common where they occur, while the males are exceedingly rare. Their habits are unknown, but are doubtless parasitic. TUBULIFERA This group of insects contains the single family Chrysididae, char- acterized by the abdomen having apjiarently very few segments, from three to five, the remainder being modified into a telescopic and retractile tube, which is drawn within the body when not required for its legitimate purjjose ; it is furnished at the extremity in the males with the organs of generation and in the females with a minute sting-like ovipositor. These insects, although of niodeiate size, are among the most beautiful of our hymenoptera, being adorned with brilliant metallic blue, green and ruby. The body is often deeply punctured, the ab- domen in some genera being almost rounded or semicircular and entire at apex, while in other genera, e. g. Ckrysis, it is usually ter- minated by a series of teeth, varying in number from two to six, the apical margin being preceded by a transverse row of deep pits. In their economy the Chrysidida; are said to differ from the pre- ceding tribe in that the females do not deposit their eggs in the bodies of other insects, but cuckoo-like, place them in the already provis- ioned nests of other hymenoptera, chiefly those of solitary wasps and bees, and being first hatched, these larvae feed upon and devour the supply of food stored up for the support of the others, which are thus starved and destroyed. Family CHRYSIDIDiE. The following synoptic table is compiled from an excellent mono- graph of the family by Mr. S. F. Aaron, jjublished in the I'ith vol- ume of these Transactions and illustrated by several plates of well drawn figures, leaving the compiler little or nothing to do but to copy the characters given of the subfamilies and genera. The family is divisible into four subfamilies, as follows : TUBITLIFERA — CHRYSIDID^.. 91 Table of Subfamilies. Face entirely convex : prothorax as luni;, or lonKer than wide, and longer than the niesothorax, with a distinct arched suture crossing its iinterior |K)rtion ; nietathorax almost equally elevated with the other por- tions, giving the dorsum of the thorax the appearance from above of four distinct parts except the prothorax; abdomen convex be- neath, the latenil margins not extending; beyond the surface of the venter; segments of the tergum 4 and 5 Cleptinee.

Thi.s series is composed of a large number of insects familiarly known as Ants (but not including the " white ants," or Termites, which belong to the Neuroj)tera), " and which are known by their habit of residing in more or less numerou.s societies under ground ; whence arises the necessity for a great number of individuals (workers or neuters) having the sexual organs and instincts rendered abortive, whereby, being freed from the latter, they are the better fitted to |)erform the labors of the community, for which purpose they are moreover destitute of wings ; whilst the male.s and females are much KAMILIFB OF HKTKKfXIYNA. 98 lef»s numerourt, j)()sser<.sing wiiigrt and arc produced only for the propa- gation of their s|)e('ie!<. * * * Thtw instH'ts have attracted the attention of the observers of Nature from tlie earliest time; and their untiring exertions for the welfare of the community, their de- votion to the young and their carefulness in the collection and storing up of various materials, have led to their being regarded ai§ examples of surprising instinctive foresight." ( Westwood). While considerable has been ])ublished concerning the habits of certain of our sj)ecies, the scientific study of these most interesting creatures has been sadly neglected, owing doubtless to the want of a knowledge of generic characters, which have nowhere, until now, been tabulated in the English language ; these tables, however, in consequence of the neglect of the study and the ignorance existing concerning our sjiecies, nnist necessarily l)e very incomplete. The c(»llection of the American Entomological Society, so rich in most of the other series, is exceedingly meagre in this, and it is notorious that in the many collections sent in, from time to time, for determination, very few ants are re{)resented and then only the most common, which may be partly accounted for by the fact that as a majority of the species are subterranean in their habits and of small size, they are apt to escape the nt)tice of collectors. The series is characterized by the petiole of the abdomen having (me or more scales, or nodes, and the societies consisting of three sexes, males, females and workers. It is divisable into five families, in the following manner: • Table of Families. Petiole with a single joint. Abdomen proper (not including petiole) not constricted between segments 1 and 2.

Nearly 200 sj)ecies have thus far been described as inhabiting our fauna, about 30 of wliich are said to be identical with European forms. Since the publication of Mr. Buckley's descriptive papers in 1866, only a few isolated species have been described ajs indigenous to our country. For exceedingly interesting accounts of the habits of some of our species, we are indebted to the observations of our esteemed friend and co-laborer, the Rev. Dr. H. C.

The winjjs are never folded and are present in both sexes, except in the females of the Mutillidie which are always apterous. The legs of the females are formed for l)urrowing, and not fitted for collecting pollen, the basal joint of the posterior tarsi being subcylindrical, and not dilatetl, fiattened and densely hairy lus in most of the Bees.

Blake, who has made the .study of this extensive family a s[)ecialty, ha.s published in the third volume of these Transactions (1871), an exhaustive "Synopsis" of the genera and s{)e('ies found in Nortli America, and subsequently a bibliogra])hical c'atal(>gue of the same. After a space of fifteen years the accumulation of material has made a revision of tht family desirable, and which ha-s just been published, by the same author, under the title of " A Monograph of the Mutillidie of Xorth America" (Tran.s. Am. Ent. Soc. xiii, 1S86). The family nuiy be divided into seven genera by the following characters : Table of Genera.

In some specimens of Myrmosa tinicoloT % the dividing nervure between the first and second submarginal cells is abbreviated, the ])osterior coxa has a short flattened tubercle or spine above, and the basal segment of the abdomen a tubercle or hooked spine l>eneath near the base. * This genus is placed here provisionally, the % being unknown. 108 GENERA OF HYMENOPTERA. The genus Isehiocerm Prov. (Faun. Ent. Can. ii, ()09), described as belonging to the Seoliidse, appears to be composed of the males of Myrmosa and Methoca, the " 9 " being % Myrmosa unicolor Say, and the % Meihoca dygia Say. The habits of the Mutillidse are believed to be parasitic, or at least those of the genus Mutilla, and carnivf)rous in the larva state. The late Frederick Smith states that from a nest of a certain species of BombuH, only two worker bees were obtained, but as many a^ seventy- six specimens of a Mutilla, the larvae of which were also found in the cells closed in as usual by the full-fed grub of the bee. Their attacks cannot, however, be confined to humble-bees, as the latter have not been found either in Australia or tro])ical Africa, and yet the Mutillidaj are common in both countries ; likewise in Mexico, the species of Mutilla are plentiful, while those of Bombxis are very scarce. Family SCOLIID^. Table of Genera. Eyes entire (except in Myzine %) 2. Eyes einarginate witliin (subreniform) in both sexes 3. 2. — Marginal cell of 9 open at apex, of % closed.

Our species of this* family have not yet been monographed, and there exists much confusion among the species of Myzine, which ap- pear to be quite variable. In the study of the genera Scolia and Elii, the admirable work of Messrs. Saussure and Sichel, entitled " Catalogus Specierum Generis Scolia" 1864, will be found to be ii.- disjiensible. Family SAPYGID^. This small family comprises some pretty species of modoiate size, mostly l)hu'k in color, spotted and banded with yellow, rarely en- tirely black. Westwood considered it as a subfatnily of the Scoliidse, but it is readily distinguished from that family by the absence of the constriction or furmw between the first and second ventral segments, by the subclavate antenme, by the smooth subcylindrical abdomen, and by the different neuration of the anterior wings which have four submarginal cells, i.e. the cubital nervure extends to the a])ical mar- gin of the wing ; moreover, the legs are slender, smooth and free froni spines and coarse hairs. Sometimes the aculeus is considerably exserted. The species are probably parasitic, cuckoo-like, in their habits, the 9 entering the burrows of certain Bees and depositing its eggs in the cells of the latter. Table of Genera. Vertex with smooth raised spots; ocelli small, indistinct; pale line on inner or- bits more or less raised or blistered; apex of antennse similar in the sexes. Eusapjga Cress.

The genus Ammophila is represented by about thirty species fri)m F08SORE8 — AMPULICID^. 113 all parts of the country ; it differs from the other genera chiefly by the two-jointed petiole of the abdomen. Pelopcens and Chnlybion are closely allied ; the species of the for- mer are black with yellow markings, while those of Chnlybion are blue or violet in color, and with the petiole of the abdomen much shorter. They construct their nests of mud in the corners of rooms, under the roofs of outbuildings and other sheltered situations. The sjiecies of Chlorion are large insects, and are among the most beautiful of our hymenoptera, being of a brilliant blue, green or violet color ; the genus is distinguished by the unidentate tarsal claws ; only two species have been described as inhabiting our fauna. Podium is represented by two species, both very rare, from the Southern States ; in this genus the form is long and slender, the pro- thorax elongate and narrowed into a neck. Isodontia has three species, all originally described as belonging to Sphex, which, however, differs by the much shorter abdominal i)etiole, and different form of the anterior margin of the clypeus. Sphex contains twelve species of wide distribution, most of them being large, handsome insects, of strong, vigorous habit. Of the other genera, Hmpactopus is represented by three si)ecies from Colorado and Texas, and of Priononyx, which has 5-toothed tarsal claws, three species have been described, two of which are of common occurrence. Family AMPULICIDiE.

It ai)j)ears to be of very rare occurrence. TBANS. AMER. ENT. SCO. (15) 8UPPL. VOL. 1887. 114 GENERA OF HYMENOPTERA. Family LARRIDiE. The followiiifr synopsis of the genera is by Mr. W. H. Patton, who has made a study of the family, and published an interesting i)aj)er on the subject in the Proceedings of the Boston Society of Natural History for 1880. Table of Genera. Eyes emarginate within; second submarginal cell petiolate Pison Spin. Eyes entire ; second submarginal cell not jietiolate. Exterior margin of mandibles scarcely emarginate. First submarginal cell shorter than the second and third combined, and di- vided by a spurious nervure; eyes of o meeting on the vertex : in- termediate tibite with two spura. Astnta Latr. First submarginal cell longer than the second and third combined, not di- vided; eyes not meeting on the vertex ; mandibles not dentate within. Liris Fabr. Exterior margin of mandibles with a broad, deep emargination near the base. Three distinct ocelli liyroda Say. Posterior ocelli distorted or obsolete. Metathorax as long as mesothorax, truncate behind ; marginal cell truncate at tip Ibarra Latr. Metathorax shorter than me.sothorax, rounded behind; marginal cell nar- row and rounded at tip ; mandibles dentate within Tacliytes Panz. Of the genera characterized above, Plmn is represented by one species from Georgia, and Astata by twelve, mostly found in the far Western States, while to Liris has been referred a single species tVoni Colorado, whose charactei-s do not altogether accord with those of that genus. Lyroda. which is distinguished from the remaining genera by having three distinct ocelli, is represented by two species. Most of the species referred to Lcirra, about twenty in number, were origi- nally described as belonging to Lnrrnda, which, according to Patton, is not generically distinct. Of Tacht/tes, sixteen species have been described. Referring to the species of this genus, Mr. Patton says : " So quick are these in- sects in their motions, and so watchful are they, that their capture is difficidt ; however stealthily they are approached while resting on the flowers, their green eyes are sure to face the intruder, and the least suspicious act sends them circling in the air, or ofl' in an exceedingly ra[)id flight." The species of this family are ordinarily found in sandy situations, where the females burrow, provisioning their cells chiefly with Or- thopterous insects. The s])ecies of 71«7///fw are said to be very par- tial to the flowers of Asclepias. F0880RE8 — BEMBECID-E. llo Family BEMBECIDiE. This family is characterized chiefly by the distinctly exserted lab- rum, which in some genera is long and rostrif'orm, and contains s' le of the largest and finest s})ecies of the Order. The genera belonging to the Stizini have been admirably treated in a paper by Mr. Patton (Bull. V. U. S. Geo. Surv. 1879), in which the characters are given in detail. The following table will assist in separating the genera : Table of Genera.

To the genus Sphecbis belong tAvo large species, which have been generally referred to Stizus; one of them, speciottits, — an exceedingly variable species found all over the United States — preys upon the Cicada, with whidi it provisions its nest ; an interesting account of the habits of this species is given by Fuller in the " American En- tomologist," vol. iii, p. 167. Megastizim has one species from the Western States and Texas, and Bembecinus two from Florida and Texas. To StiznA two sj)ecies are referred, one of which, Servillei St. Farg., ha.'^ not yet been identified, while the other, tmieinctus Say, is very common in the far AVest and Southwest ; it is black with a broad reddish band on the abdomen, and the wings broad, violaceous- black, with the extreme tips subhyaline. The Bembecini have not yet been monographed, and considerable confusion exists in the species belonging to the genera Bembex and Monedula, of which seven are referred to the former and nine to the latter, while Microbembex and StenioUa have each one sj)ecies. Family NYSSONID^. Since the publication of Dr. Packard's " Revision of the Fossorial Hymenoptera" (Proc. Ent. Soc. Phil, vi, 1866-67), in which this family was reviewed, nothing has been done in the study of our species, except those belonging to Nymon and allied genera, which have been noticed in a pajwr published in the ninth volume of these Transactions, 1882. The genera are readily separated by the characters given below. Table of Genera. Second submarginal cell not petiolate 2. Second submarginal cell petiolate 3.

Submargiual cell confluent with the first di.scoidal cell, only sepai-ated from it by a very indistinct nervure; postscutellum with a membranous wing-like appendage on each side ; metathorax with a curved spine near the base Oxybelus Latr. The genus Trypoxyton is readily recognized by the renifonn eyes and long clavate abdomen, and is the only genus in the family where the neuration of the posterior wings is complete. The number of described species is few, and not unconnnou. Rhopalam has the abdomen petiolate, with the apex of the first segment nodiform ; the species are of small size, and only two have been described. Crabro has numerous species, varying in size from moderately large to quite small, and which have been divided into many sub- genera, the characters founded chiefly on the armature of the legs ; among these is Blepharipus, to which several North American species have been referred ; these are all of sitiall size, with subpetiolate ab- domen, and with a single exception, have the abdomen entirely black. Thyreopns has generally been ranked among the subgenera, and doubtless properly so, but it is placed in tlie table given above because of easily recognized and tolerably constant characters. Anaerabro is represented by a single small, robust s|Kicies, having somewhat the a])pearance ot Oxybelm, and at once distinguished by the linear form of the second discoidal cell. Eniomognathus, distinguished by the hairy eyes, has, as far as known, but a single representative in our fauna, and which occurs in Texas. Oxybelus is remarkable for the armature of the metathorax and confluence of the submarginal and first discoidal cells. The genera and species are described at length by Packard in his " Revision" previously referred to. DIPLOPTKRYGA — MASARID^E. 123 DIPLOPTERYGA. This series consists of the true wasps, and is characterized chiefly by the wings being folded longitudinally in repose (more or less in- distinctly so in the Masaridae ), in which res{)ect it differs from all the other series, except in the Chalcid genus Leiicospis. The prothorax is prolonged backwards to the base of the wings, the eyes are reni- form and the legs are not formed for burrowing in the ground, being free from spines and bristles. The solitary species consist of two sexes, % and $ , and somewhat resemble the Fossores in their habits, constructing their nests in sandy banks, in crevices of stone-walls, in holes bored by other insects in wood, etc., using their powerful man- dibles in excavating ; some genera, e. g. Eumena, construct mud- nests, in the o})en air, on stems of weeds, or under leaves, or loose bark of trees. On the other hand the social species consist of three sexes, % , 9 and § , and are natural paper makers, constructing their nests on trees, or in corners of building, or under the roofs of outbuildings, although some species, e. g. Vespa vulgaris and ger- manica, commonly known as " yellow-jackets," build their nests un- derground, as most country boys know by painful experience. A very interesting article on the habits of these insects, by the late B. D. Walsh, will Ve found in the first volume of the " American En- tomologist,' pp. I08-I43. The series is divisible into three families, in the following manner : Table of Families. Antennse clavate or knobbed at tip, the joints of the club generally soldered together; scutellum large, narrowed and rounded posteriorly, super- posed upon the postscutellura ; anterior wings indistinctly folded in re- pose ; solitarj'. sexes % 9 MASARID^. Antennae filiform or subfiliforra ; scutellum transverse, truncate posteriorly, not superposed upon the postscutellum ; anterior wings distinctly folded in repose.

Family MASARIDiE. This small, but beautiful family is at once recognized by the clavate or knobbed anteimte, long in the males of Mamrii, and short in the females and in both sexes of Euparagia ; the single species of the 124 OENERA OF HYMENOPTERA. latter genus, found in Nevada and California, is quite small in com- parison with the generally large, fine species of Mnsarls, of which seven have been described from Texas, Colorado and California. The geographical distribution of the s{)ecies of this genus is remark- able, the only other two representatives known being found in North Africa. Nothing is as yet known regarding their habits. The following characters will sufficiently separate the genera : Table of Genera. Anterior wings with two complete submarginal cells, the second subniarginal re- ceiving both recurrent nervures ; antennse * f % long and knobbed at tip, that of 9 short and clavate Masaris Fabr. Anterior wings with three complete subniarginal cells, the second and third snb- margiuals each receiving a recurrent nervure ; antennae rather short and clavate in both sexes Euparagia Cress. Family EUMENID^. In this family, comprising the Solitary Wasps, the antenna? are filiform or nearly so, and often terminated by a hook in the % ; the intermediate tibiie have but one apical spur and the tarsal claws are unidentate. The genera with sessile or subsessile abdomen are closely allied, the only charactei-s, so far discovered, by which they can be separated, are those found in the structure of the mouth-parts, which unfortunately are oft,en concealed ; there are, however, certain su|)er- ficiul differences of form and facies, impossible to describe intelli- gently, but which enable a practiced eye to distinguish the genera without recourse to an examination of the tro])hi. The genera and s|)ecies of this family, including also the iVIa-Jarida;, have been elaborately monographed by Dr. de Saussure, in his ad- mirable *' Synopsis of American Wasps," ])ublished in 1875 by the Smithsonian Institution, and which will be found to be indis[)ensil)le to those desiring to study this interesting and beautiful group of in- sects. The following table is about the best that can be offered at present for the sejmration of the genera : ' Table of Genera. Abdomen jietiolate.

Labial palpi long and slender, 3-joiuted, the second and third joints strongly compressed and bipectinate, fringed with long hairs. Pterochilus Klug. Of the above genera Zethus and Eumenes, which have petiolate abdomen, are easily separated by the form of the head. The former genus, so abundant in species in tropical and subtropical America, has but one representative in our fauna. In the list six sj)ecies are referred to Emnenes, one of which, jV«/erna, is widely distributed and common ; it constructs a spherical nest of fine yellowish clay, which may often be found adhering to leaves, small twigs, or fastened against walls ; within this little s])here, the insect places an egg to- gether with a provision of caterpillars tor the nourishment of the larva, and then seals it up. Of Moiiobia we have two species, one of which, qiiadridens, is com- mon in most of the States east of the Mississippi. Nortonia is re{> resented by one species, of rather rare occurrence, and found in the .Vtlantic States from Connecticut to Florida. Odipierux has numerous species, widely distributed over the coun- try ; they are divisible into several subgenera, the characters of which are given in the above table ; many of the species are ornate with gay colors, and make a very pretty collection. Pterovhilm, which is characteri7,ed by the long, slender labial palpi fringed with long hairs, is representetl by ten species, all from tlie far Western States ; they are gaily colored, handsojue insects, of medium to large size, and generally rare. 126 GENERA OF HYMENOPTERA. Family VESPID^. This family comprise the Social Wasps, commonly known as "Hornets" and "Yellow-jackets," and is easily separated from the preceding by the two-spurred intermediate tibiae, and simple tarsal claws. They are all ])aper-makers, not out of rags, but out of wood, and according to Walsh, " alighting upon some wooden surface ex- posed to the weather, they gnaw off with their strong jaws the minute filaments of wood, which have become partly detached by the action of the elements, and chew them up into a fine pulj), which they after- wards spread out into thin sheets of strong, gray, weather-proof paper that fi)rm the material of their nests," which are found generally sus- pended from the branches of trees, and sometimes in the corners of outbuildings. Some species, e. g. the " Yellow-jackets," as previously noticed, build their nests underground and presumably much on the same principle as those built above ground. The species of Polides, which differ by the more slender form, longer metathorax and sub- sessile or subpetiolate abdomen, build combs or a series of paper cells in various sheltered places, principally on the roof-timbers of barns and other outbuildings, but always without an envelope or covering, as is used by most of the species of Vespa. There do not appear to be any well-marked distinguishing characters between the females and workers of Polides, and probably also of Polyhia, which diflers only in the form of the abdomen. The characteristics of the genera belonging to this family are as follows : Table of Genera. Abdoiiicn sessile, broad and truncate at base ; metathorax very short and trun- cate; the basal nervure joins the subcostal nervure some distance before the stigma Vespa Linn. Abdomen subsessile or subpetiolate, long, fusiform ; metathorax as long as broad, oblique above : the basal n§rvurc joins the subcostal nervure at base of the stigma Polistes Latr. Abdomen petiolate, short and ovate beyond the first segment ; metathorax and neuration much as in Polistes Polybia St. Farg. Our species of this family are in much confusion, and need a thor- ough revision. The species of Polistes are exceedingly variable, and there is no doubt that a careful study of a large collection of speci- mens will result in a marked reduction of the number of species. Polybia has but a single representative in our fauna, fiavitarsis Sauss., quite a common insect in California. . ANTHOPHILA. 127 Of Vespa, the black and white species, maeulata, is the most com- mon, building large nests on trees, etc., while germanica and vulgaris, black and yellow species, also abundant, build underground. ANTHOPHILA This extensive series, containing the interesting family of Bees, is (characterized chiefly by having the basal joint of the posterior tarsi more or less dilated, flattened, generally hirsute and furnished with apparatus for collecting and conveying pollen, except in the parasitic species, in which this joint is narrower, simple and destitute of pol- liniferous organs. Mr. E. Saunders, in his Synopsis of the British Bees (Trans. Ent. Soc. London, 1883—84 has), found the only satisfactory structural character primarily dividing the Anthophila from the rest of the Aculeata, to be the form of the hairs of the body, which he says are always more or less branched or plumose, at least those of the thorax, while in the other series the hairs are simple or at most twisted, never branched or plumose. This character, which may be a very excel- lent one, has not been adopted in this synopsis because it is in many cases microscopic, and hence difficult to observe. The classification of the Anthophila depends considerably upon the variations in the structure of the mouth-parts, which are highly organized (and are admirably described and figured by Prof. West- wood in his " Modern Classification," vol. ii, pp. 256-57), hence the characters adopted for the separation of the two families, into which the series is divisible, are in the toniparative length of the labium and mentum, as given in the table of families, and for convenience rejieated here : Labium flattened, shorter than the mentum ; basal joints of the labial palpi not unlike the following joints. ANDRENID.ffi. Labium slender, not flattened, longer than the mentum ; basal joints of the labial palpi elongate APID^ffi. In the Andrenida; the sjiecies are all solitary, each consisting only of males and fenuiles ; while in the Apidae, the species belonging to the genera Bovibm and Apis are social, and consist of males, females and 128 GENERA OF HYMENOPTERA. workers. By some systematists the latter family is restricted to the social species only. In the larva state all the species feed on |>ollen or honey stored up by the parent, the parasitic species, cuckoo-like, consuming the food provided for the legitimate inhabitant of the nest. In tabulating the genera belonging to this series use has been made of external characters when possible, simply because they are more easily seen, and although the arrangement is far from being a natural one, a« will be observed by the way in which the genera of the two families are intermixed in the tables, yet it will be found a nmch easier mode of identification than if the more natural, though often invisible characters, founded upon the modification of the mouth parts, were used. These latter are generally retracted and hidden in cabinet specimens, and unhess drawn out and arranged before be- coming dried, are troublesome to get at, and moreover cannot be dis- tinctly seen without the aid of a lens of more than ordinary power. From the fact that the characters separating the two families of this series are taken from the form of the tongue, and that no exter- nal characters have been found that will distinguish them, the genera belonging to both must necessarily intermix in the following table : Table of Genera.
