HYMENOPTEROUS INSECTS

THE COLLECTION

OF THE

BRITISH MUSEUM.

PART I.

ANDRENIDA AND APIDA.

LONDON:
PRINTED BY ORDER OF THE TRUSTEES.
1853.

PREPAC &.

THE principal object of the present Catalogue has been
to give a complete list of all the known species of ANDRE-
nip# and Aprp#, at the same time indicating those at

present contained in the Collection of the British Museum.

This part of the Catalogue has been prepared by
Mr. Freperick Smitu, who has taken every care in the
determimation of the species, the references to the syn-
onyma, and in the descriptions of such species as hitherto

are apparently undescribed.

The remaining Parts will follow as soon as they can be

completed.

Genus 14. PARASPHECODES.

F. Smith’s MSS. (Details, Plate ITI.)

The species of this subdivision closely resemble in general ap-
pearance those of the genus Sphecodes, but the females possess
the characteristic anal rma and also the appendage to the la-
brum of the females of the genus Halictus; the males also have
an elongate cylindrical abdomen, and have the clypeus produced
and yellow at the apex, as is usual in the same genus ; the tongue
offers no positive distinction from some of the species of Ha-
lictus, which differ in having that organ more or less elongate and
acute, but the superior wings have always the first recurrent
nervure united to the second transverso-cubital nervure. All the
species are from Australia and Van Diemen’s Land.

Obs. This species very closely resembles the H. leucozonius of
Kirby, but differs in the sculpture of the metathorax, and also in
having the second submarginal cell broader. From an examina-
tion of a large number of this apparently abundant species, it is
found to vary in the grooving of the enclosed space at the base
of the metathorax, the grooving not being always smooth or
equally deeply sculptured; the abdominal fasciz are frequently
nearly obsolete, in others broader, sometimes narrower ; thus in
its varieties resembling those of the H. leucozonius. The male
is united, from the fact of their having been received together
from both localities on numerous occasions.

having the abdomen less shining, caused by its more closely and
distinctly punctured abdomen, and by having four uninterrupted
white bands ; the first covers the basal margin of the second seg-
ment, though less defined, as well as the apical margin of the
first.

having a purple lustre, the pubescence on the legs silvery-white,
the spies at the apex of the tibiae white. Abdomen bright
shining blue, having a purple tinge, the anal fimbria black.

Male very similar to the female, but differs in having the an-
tenn nearly as long as the head and thorax, in the absence of
the red spot beneath the wings, in having the scutellum black
and a broad black stripe down the middle of the disk of the tho-
rax ; abdomen elongate and black.

Genus 20. AGAPOSTEMON.

(Details, Plate IV.)

Head subtriangular; antenne elongate in the males; the la-
brum transverse and concave in the females, produced into an
elongated lobe, which is sublanceolate and closely frmged at the
sides with stout flat hairs ; the apical half of the lobe is produced
into an elevated carina, which passes off in an oblique direction
to the margin on each side; the labrum of the males transverse,
very convex and divided by a shallow groove in the centre, pro-
duced in front into an angular lobe distantly ciliated on its an-
terior margin. Mentum elongate, in the females more than four
times the length of the labium ; in the males the labium is about

half the length of the mentum; the paraglossz about half the
length of the labium; labial palpi four-jomted; maxillary palpi
six-jointed, the basal joint of the former as long as the three fol-
lowmg; the maxillary have all the joints of about equal length ;
the wings as in the genus Halictus. Abdomen in the females
furnished with an anal rima.

Obs. M. Guérin has indicated the separation of these insects
from the genus Halictus, and has proposed the name Agaposte-
mon, but without giving the generic characters.

in front and on the margins of the scutellum and post-scutellum
a fringe of short ochraceous pubescence, the legs have a pale pu-
bescence having more or less of a yellow tinge; the floccus and
scopa on the posterior pair have a glittering silvery lustre, on the
tarsi beneath it is fulvous, the apical joimts of the tarsi pale rufo-
testaceous, as are also the tegulz and nervures of the wings, the
latter hyaline ; the apical margims of the abdominal segments

Obs. The situation of this fine insect is not probably that at
Smee assigned to it; but the only specimen known is in the
National Collection, and those parts of the oral organs which
might determine it could not be sufficiently exammed. The
name of the genus sufficiently indicates its general appearance,
and seems to poit out its situation.

Genus 7. PTILOTHRIX.

Ptilothrix, F. Smith’s MSS. (Details, Plate VI.)

Head not quite as wide as the thorax, ocelli placed in a slight
curve on the vertex ; the labium twice the length of the mentum,
broadest about the middle, tapering towards the apex, which is
blunt ; the paraglosse half the length of the labium, attenuating
to a point at their apex ; the labial palpi rather shorter than the
labium, four-jointed, the first and second elongate, placed end
to end, the two apical jomts minute, placed at the side of the
second jomt at its apex; the maxillary palpi six-jointed, the
three basal joints of equal length, the three apical ones of equal
length, but shorter than the basal jomts ; the anterior wing
having one marginal and three submarginal cells, the marginal
cell slightly rounded at its apex; the second submarginal cell

much narrowed towards the marginal, the third slightly so; the
posterior tibize and the basal joint of the tarsi furnished with a
thin scopa of long pubescence.

1. PriLoTHRIX PLUMATUS.

Female. Length 5 lines.—Black, the clypeus and labrum
have large scattered punctures and are thinly clothed with
griseous pubescence, above the insertion of the antenne and on
the cheeks it is dense, short, and dark fuscous; the flagellum
ferruginous beneath, tips of the mandibles yellow. Thorax, the
disk densely clothed with short fulvous pubescence, thinner and
paler on the sides; the legs red, the cox black; the anterior
coxe and femora fringed with black pubescence; the interme-
diate and posterior coxz and trochanters friged with cinereous
pubescence ; on the anterior tibie and tarsi above, and on the
posterior tarsi within, it is fuscous, otherwise the legs have a glit-
tering pale yellowish pubescence, having a little which is snow-

-white at the apex of the posterior tibiz ; wings hyaline, and
having a yellowish tinge towards their base, tegule and nervures
pale rufo-testaceous. Abdomen ovate, the base fringed with
short fulvous pubescence; the margin of the first and three fol-
lowing segments has a broad fascia of very short decumbent
pubescence, broadest in the centre; the two apical segments
covered with rigid black pubescence.

Obs. This beautiful species is remarkable for having the entire
pubescence plumose, each individual hair being pectmate; that
on the metathorax, viewed under a pocket lens of good power,
resembles fine down; even the short pubescence which forms the
fascia on the abdomen is equally beautiful.

50. OSMIA SIMILLIMA.

Female. Length 43 lines.—Steel-blue, head as wide as the
thorax, the face, sides of the thorax and abdomen thinly covered
with griseous pubescence, the entire insect closely and rather
strongly punctured ; the wings subhyaline, their apical margins
faintly clouded ; the legs have a griseous pubescence, that on the
tarsi beneath brown; the abdomen beneath densely clothed with

thorax, setaceous, fulvo-testaceous beneath; the face thickly
covered with long white pubescence, a similar pubescence is also
more thinly scattered over the vertex, thorax and base of the ab-
domen; wings as in the female ; the apical segment notched in
the middle; beneath, the ventral segment is bidentate.

Obs. This species very closely resembles the Osmia cerules-
cens; the female is difficult to distinguish; it differs m bemg
larger and of a brighter blue, and in wanting the smooth, shining
space below the post-scutellum always present in O. c@rulescens.
The male differs in the form and pale colour of the antenne
beneath, and in the margin of the apical segment being deeply
notched in the middle and entire laterally.

Museum, to all of which the brief description of Fabricius would
equally apply; im order to distinguish the differences, the fol-
lowing additional particulars will be necessary.

M. mystacea.—Head, thorax, legs and basal segment of the
abdomen black, the latter having on its apical margin a band of
fulvous pubescence, with which the rest of the abdomen is co-
vered; above the insertion of the antennz, as high as the an-
terior stemma, the face is covered with griseous pubescence ;
below the antenne on each side is a little black pubescence ; the
clypeus is rounded in front and has a slight notch m the centre ;
the mandibles are flat exteriorly and longitudimally grooved to-
wards their apex, and covered with elongate punctures, armed
at the apex with two teeth; the spmes at the apex of the poste-
rior tibiz black.

The male is coloured as in the other sex, but the face has a
tuft of white pubescence between the antennz, the anterior
margin of the clypeus has a long beard of the same colour; the
legs are clothed above with black pubescence.

the tarsi fulvous beneath, the claws rufo-testaceous. Abdomen
very convex above, the three basal segments have on each side a
short white marginal fringe; the fifth and sixth segments red,
except the extreme base and sides of the former, and clothed
with bright fulvous pubescence ; the pollen-brush very pale
yellow, the extreme apex fuscous.

Obs. This species very closely resembles the M. mystacea ; in
the Museum Collection are examples from India and the Isle of
France: in all probability this is the insect described by M.
Guérin: the following differences distinguish it from M. my-
stacea,

The abdomen entirely fulvous-red, the basal segment having
no black pubescence on its superior surface ; the pubescence of
the head is entirely black ; the face a little before the imsertion
of the antennz is obliquely truncated and roughened by irregular
sculpture ; the anterior margin of the clypeus is transverse, and
on each side is slightly produced before reaching the base of the
mandibles; the mandibles are rounded exteriorly and have no
grooves towards the base, but have two short ones at their apex ;
the spines at the apex of the posterior tibiz red.

Male.—In colour agreeing with the female; the clypeus is
convex in this sex and has a thick fringe of white pubescence on
its anterior margin, a tuft of the same colour between the an-
tennz, and a line on each side along the margin of the eyes;
between these it is black; the calcaria as in the female are red.

the sides, beneath, and on the legs it is white, the anterior femora
are thickly frmged ; wings fusco-hyalme, their nervures black ;
the margins of all the segments and the sides of the basal one
fringed with white pubescence ; the base deeply emarginate ; the
margin of the apical segment has a central rounded incision, form-
ing two incurving teeth; beneath, the margin of the venter has
on each side two short teeth, directed inwards, between the inner
ones a raised prominence.

Obs. This species is distinguished by its broad parallel form,
the abdomen, head and thorax being of the same width.

an ochraceous hue; the legs and apical segments of the ab- —
domen have a covering of black pubescence; the tarsi beneath —
fulvous ; the wings hyaline, faintly clouded at their apical mar--
gins. The brush on the abdomen beneath is of a blackish —
brown.

cence is longer, that on the face being very dense and of a pale
yellow colour; the apical joint of the antennz dilated and com-
pressed: the anterior legs pale testaceous ; the apex of the
store and the tibiz above black, the tarsi dilated and fringed
beneath with pale hairs; the intermediate tarsi have a yellow
pubescence above, and are, as well as the posterior pair, fulvous
beneath, their claws ferruginous ; the apical segment deeply
notched, and on each side denticulate ; beneath the abdomen on
the ventral segment are two obtuse spines, and a little before
them a central acute one.

clus. synon. ?

Female. Length 6 lines.—Black, the face covered with pale —
ochraceous pubescence, brightest towards the margin of the cly-
peus, on the vertex and disk of the thorax it is dark fuscous, on
the sides of the thorax, beneath, on the legs above and at the
sides of the basal segment of the abdomen it is of a very pale
yellow, being nearly white at the sides of the metathorax, and |
short and sparing on the legs; wings subhyaline, the apical mar-—
gins faintly clouded; the tarsi fulvous beneath, on the anterior —
and intermediate pairs it is of a bright golden-yellow above, the —

claws ferruginous. Abdomen short, broad and slightly convex
above, the segments have narrow pale marginal fascize, usually
much interrupted on the three basal segments; beneath, the
pollen-brush is of a golden-yellow.

Obs. This insect is probably the female of M. frigida,
having been captured m various and the same localities as that
species.

Hab. North America (E. Doubleday, Esq.) ; Nova Scotia (Coll.

Lieut. Redman).

150. MEGACHILE FRIGIDA, 0. Ss. B.M.

Male. Length 5-6 limes.—Black, the face densely clothed
with bright yellow pubescence, the apical joint dilated and com-
pressed ; the disk of the thorax thinly clothed with ochraceous
pubescence, that on the sides and also on the sides of the basal
segments of the abdomen is pale ochraceous ; the anterior legs
pale testaceous, the apex of the femora and the tibize above, ex-
cept its apex, rufo-fuscous ; the tarsi broadly dilated, and having
beneath a dense fringe of yellowish-white pubescence ; the first
joint of the tarsi has above a narrow fuscous fringe; the femora
beneath have a long loose fringe of nearly white pubescence ;
the intermediate tarsi covered with pale yellow pubescence, and
having a long loose fringe behind of the same colour; the pos-
terior tibiz curved. The apical segments of the abdomen curved
beneath, the margin of the apical segment serrated and deeply
notched in the middle.

Obs. This species very closely resembles the European one,
M. maritima, from which it differs in wanting the black spot on
the second joint of the anterior tarsi beneath, and in not having
the mandibles yellow on their inferior margins; the posterior
femora are also much less thickened and the posterior tarsi con-
siderably longer.

drate, the face having on each side a httle griseous pubescence ;
the anterior margin of the clypeus produced in the middle, and
having on each side a short blunt tooth; the mandibles very
stout, roughly sculptured above, and deeply channeled towards
their apex, which is armed with two teeth, the apical one long

and acute. Thorax, the disk thinly sprinkled with fuscous pu-
hescence, that on its sides is griseous ; the wings fuscous towards
their anterior margins, the nervures dark fuscous ; the legs have a
thin cinereous pubescence, that on the tarsi is bright fulvous-yel-
low. Abdomen, the sides of the basal segment and apical margins
of all the segments fringed with white pubescence, usually more
