INTRODUCTION. 



HYMENOPTERA. 

The Order Hymenoptera comprises the Sawflies, the Gallflies, the 
Ichneumons, the Ants, the Sand- and Wood-wasps, the Wasps 
proper, and the Bees. 

It is now generally admitted that Hymenoptera have a right 
to be considered the most highly developed mentally of all insects. 
Certain forms, as the ants, the social bees, and wasps, live in large 
communities, have a regular and organized division of classes and 
labour, and frequently maintain complex social relations with 
insects of other orders that, as guests or parasites, harbour in 
their nests. 

The Hymenoptera are distinguished from all other insects by 
the following general characters : — 

Mandibles always present and conspicuous, even when the rest 
of the oral parts are more or less changed and abnormal. In the 
higher forms, the thorax and abdomen are remarkably modified. 
The first segment of the abdomen is separated from the remaining 
segments by a complex and extremely flexible joint, and is united 
to the posterior portion of the thorax, forming with it a consoli- 
dated mass, which has appropriately been called the " alitrunk " by 
Dr. Sharp. Wings four, membranous, with comparatively few 
nervures, enclosing spaces or cells irregular in shape and limited 
in number ; the posterior wings smaller than the anterior. 
Abdomen in the female furnished, at its apex, with a saw, borer, 
ovipositor, or sting. 

Larva in the more highly developed genera and famihes always 
vermiform and footless, but in some of the lower forms with 
thoracic and abdominal legs, the latter frequently numerous. 
Pupa inactive, the parts as in the imago, but more or less 
colourless and enveloped in a thin delicate membrane. 

The head of a hymenopterous insect is quite free from the 
thorax and often remarkably mobile. It varies but little in shape : 
the vertex (figs. 1, 2, & o, «) is usually more or less convex and 
transverse, very often broad and subquadrate ; the clieeh (fig. 1, 6) 
lies behind the eye, and when the lower rim of the latter does not 
extend down to the base of the mandibles it includes the space 
between the eyes and the mandibles; \\\q comjJound eyes {^o. l,c; 
figs. 2 & ^, r/, c^) occupy the sides of the head, and are built up 
generally of many facets, but in some of the ants are reduced to 
one facet. On the vertex (sometimes a little below it) are placed

IV INTBODUCTION. 

the simple eyes or ocelli (figs. 2 & 3, b), three in uumber; these 
may be present or absent, complete, or distorted as in some of the 
Sphegidcf. Below the vertex is the front (figs. 2 & 3, c), on which 
are inserted the antenna' (fig. 1, d-f; figs. 2 & 3, e-f). The parts 
ot the autenna are the scape (fig. 1, d; figs. 2 & 3, ?, e) and the 
flngellum (fig. 1, e-f; figs. 2 & 3, /, /). The scape or basal joint of 
the antenna is sometimes elongate as in the Heterogyna or Ants :

b, cheek ; c, compound eye ; it, scape of antenna ; e-f, flagellum of 
antenna; q, elypeus ; h, mandible; J, maxillary palpus; k, labial palpus; 
/, portion of maxilla. 

the Jlagellum is, as a rule, divided into eleven joints in the female 
and twelve in the male ; the apical joint or joints in the latter sex 
being sometimes more or less modified, e. g., curved into a hook as 
in some of the Diploptera, spined aud excavate below as in some 
of the Fossores (Bembex), or dilated and flattened as in a few of 
the AntJiopliila. Below the base of the antennae is a more or less 
conspicuous and shield-like plate called the clypeus (figs. 1,2, & 3, (/), 
the form of which affords valuable specific or, sometimes, generic 
characters. Beneath the elypeus and hinged on to its anterior 
mar»in is the labrum (figs. 2 & 3, h) : this is variable in size 
and form, and is frequently entirely concealed underneath the 
elypeus, while in a few genera it is exserted aud elongate to an 
extraordinary extent. The part underneath the labrum is the 
epipharynx. The mandibJes (tig. 1, 7i: figs. 2 & 3, i, i) are hinged 
to the apex of the cheeks below and fold over or under the 
labrum ; under all modifications in size and shape they remain 
conspicuously cutting or crushing machines. On the underside 
of the lower or fate portion of the head is a hollow into which fit 
the softer mouth-parts when at rest. These latter consist chiefly 
of the labium and the maxillae (figs. 4 & 5). The labium is 
attached to the side walls of the buccal holloAv, through narrow 
joints, the lora and the cardines. The upper portion of the 
labium forms the sulmeninm and mentum, ; from the apex of the 
latter at the sides spring the labial ^alpi (fig. 4, A,-, A.-), and from 



INTIIODUCTION. 



between the labial palj^i, the I'lgula or tongue (tig. 4, m), en- 
sheathed at base by the parar/lossce (fig. 4, I, I). Both the ligula 
and paraglossae are very variable in form. On each side of the 
labium are the mcLvilhn (tig. 5), sheath-like organs with a basal 
portion, the stipes (fig. 5, n\ and an apical lobe, the galea (fig. 5,p).

Close to the junction of the stipes with the galea spiings the

parts are of great value in the classification of the Hymenoptera. 

The thorax proper is composed of three segments — the pro-, 
meso-, and metathorax. The jprothorax is I'emarkable for the 



INTRODUCTION. 



detachment of the side pieces (fig. 8, a. a) from the notum and 
their great development. In many species these side pieces 
completely overlie the presternum. The mesothornx consists of a 
broad, generally convex plate, the viesonotum (fig. 6, t-, & fig. 7, h) ; 
a posterior portion, the scutum or scutellum (tig. 6, h,& fig. 7,/);

side pieces, the episternum (fig. 6, i) and epimeron (fig. 6,^), these 
two united making up the mesopleiiron ; and lastly the meso- 
siernum (fig. 8, c, c). The mesonotum is frequently divided by 
oblique longitudinal grooves, the side pieces being called the 
parapsides (tig. 6, d, & fig. 7, c, c). The metathorax similarly has 



INTRODUCTION. VU 

a dorsal plate, the metanotum (fig. 6, h^ n^ ; fig. 7, g, 7t\ A^), the 
anterior portion of which is called the postscutellum ; side pieces, 
episternum (fig. 6, I) and ejiimeroii (fig. 6, m), the two together 
forming the metapleuron ; and the metasternum (tig. 8, /, /). 

In all the higher Hymenoptera. as noted above, the basal seg- 
ment of the abdomen is closely amalgamated with the metathorax 
(fig. 6, ?i, & fig. 7, A). This segment has been varionsly called 
"Latreille's segment," the "propodeum," or the "median segment." 

Throughout this work I have preferred to use the term "median 
segment 'as being most generally known. The median segment has 
very often short oblique lateral slits or grooves with their anterior 
edge raised and prominent : these slits or grooves are the so-called 
" false stigmata '' (fig. l,j, j). The ventral plate of the median seg- 
ment (fig. 8, h) can generally be made out with but little difficulty. 
The sculpture of the thorax and of the median segment is largely 
used in the discrimination of the species. 

The appendages of the thorax are the legs and the wings. The 
legs, as in aU insects, are six in number, attached to the underside 
of the thorax by their basal joints, the coxce (fig. 9, a) : the fore 
legs are articulated to the prothorax, the intermediate pair to the 
mesothorax, and the posterior to the metathorax. Below the 
coxae are the trockanters (fig. 9, h) : these may be simple, in one 
piece, as in the bulk of the Aculeata, or in two with an articula- 
tion between, as in most of the Parasitica. Articulated to the 
trochanters below are the femora (fig. 9, c) ; below these the tibice 
(fig. 9, d), and below the tibiae the tarsi (fig. 9,/). The tarsus in 
Hymenoptera is 5-jointed, with very few exceptions : the basal 
joint (fig. 9, g) or metatarsus is usually the longest, the apical 
joint (fig. 9, I) is invariably provided with two claws (fig. 9, m, m), 
which may be simple, bifid, or dentate beneath. Between the 
claws lies the pad or pidvillus, which, however, is absent in many 
genera. 

The legs of Hymenoptera, especially the tibiae and tarsi, are as 
a rule more or less furnished with spines, stiff hairs, or pubescence 
of some kind, the presence or absence and disposition of which 
afford valuable characters for the discrimination of species and 
even of genera. 

The ivings (figs. 10 and 11) are invariably four in number, and 
nearly always present in the imago in both sexes. The females, 
and more rarely the males in a few forms, are apterous. Among 
the Heterogyna, or Ants, the fully-developed females and the 
males only are provided with wings, the neuters or workers (more 
correctly the females with arrested development) being apterous. 
The anterior wings are attached to the sides of the mesothorax 
(fig. 6/, site of attachment of fore wing), and the points of junction 
are protected and covered by little plates or shields, the tegtdoi 
(fig. 6, c ; fig. 7, d, d). The posterior wings are borne by the 
metathorax, and their points of junction with the thorax are 
slightly lower in a vertical direction than those of the fore wings. 



INTfiODUCTIOIf. 



The wings, as already stated above, are membranous, divided by 
nervures into irregular spaces or cells which in the tore wing are 
never more than twenty in number, and in the hind wing fifteen.

The winged Hymenoptera are, as a rule, capable of swift and 
sustained flight. For this purpose they possess a wonderful 
arrangement (one of the most beautiful in nature) for linking 



INTRODUCTION. ix 

together during flight the fore and hind wings. Examined with a 
good lens, the fore wing is seen to have a fold along its posterior 
margin, while on the anterior or costal margin of the hind wing a 
row of hook-shaped bristles or hairs can be easily detected. When 
the ^^•iugs are expanded these hooks, or hamuli as they are called, 
catch on firmly to the fold in the fore wing, and the fore and hind 
wing on each side are enabled to act in concert, having the appear- 
ance and all the firmness of a single expanded membrane. The 
names of the uervures and cells in the wings are included in the 
explanation nnder figures 10 and 11. The number and disposition 
of these nervures and cells are of considerable importance in the 
classification of the Hymenoptera. 

The abdomen (fig. 12) is attached to the thorax direct or through 
the median segment, the articulation being either broad and not 
very flexible, as in the lower forms, or narrow and possessed of 
the utmost flexibility, as in the bulk of the families into which the 
Hymenoptera are divided. So remarkable is this flexibility, that a 
bee or a wasp is not only able to twist its abdomen and sting in 
all directions posteriorly, but many species can, and do, double the 
abdomen underneath the thorax, and protrude the sting in front 
of the head. 

As a rule the abdomen, in the higher Hymenoptera, consists of 
six visible segments in the female and of seven segments in the 
male, each segment formed by a dorsal and a ventral plate (fig. 12, 
a-a^, h-b"). 

The epipygium, or dorsal portion of the apical abdominal 
segment, and the lujpopygium, or ventral portion of the same, 
together form what is called the pygidiam. Occasionally the term 
" pygidial area " is used, and refers to a portion of the epipygium 
which in certain forms is margined and llat, not convex *. 



The Hymenoptera fall naturally into two great divisions or 
suborders, characterized by the difference in the articulation of the 
abdomen with the thorax referred to above, and by more profound 
difl'erences in the form and life-history of the larvae. The external 
difference in the imago may be tabulated as follows : — 

I. Suborder SESSILIVENTEES. 

Median segment (1st true abdominal segment) not completely 
amalgamated with the thorax, the joint between the thorax and 
abdomen broad. 



* For an accurate and full account of the external and internal anatomy of 
the Hymenoptera, see the ' Cambridge Natural History,' Vol. V., Part Insecta, 
by Dr. D. Sharp.

II. Suborder PETIOLATA. 

Median segment (1st true abdominal segment) completely amal- 
gamated with the thorax ; joint between the 
thorax (iucluding the median segment) and the 
abdomen slender, highly mobile. 

A good representative form belonging to ilie 
Suborder Sessihvenires is shown at fig. 13. 
This is an undeseribed species, from Sikhim, of 
the genus Hylotoma belonging to the family 
Tentkrediaidcc or Sawflies. 

The Suborder Petiolaia, containing by far the 
larger number of the famihes in the Order, can 
be subdivided into the 

(1) Paeasitica. — Trochanters of the legs in two portions with 
an articulation between : female furnished wdth an ovipositor. 

(2) AcuLEATA. — Trochanters undivided ; female furnished with 
a sting. 

The character derived from the trochanters is liable to exceptions. 
Some of the Jchneumonidce, which belong to the division Paeasitica, 
have undivided trochanters ; while on the other hand some of the 
Sphegidce {e. g., the genus Nysson), true aculeates, are markedly 
ditrochous. 

The wing-neuration in the IchneumonidcB, however, is generally 
so marked that, ^vith a little care, confusion between the forms in 
the different divisions can be avoided.

INTRODUCTION. ^1 

The AcuLEATA have been divided into Series or Tribes. All 
divisions, however, more comprehensive than families must be 
considered moi*e or less conventional. 

Key to the Tribes of the Aculeata. 

A. Apical abdominal segments highly retractile ; 

abdomen with only three, four, or live visible 
segments ; wings when at rest without a 
longitudinal fold TUBULIFERA. 

B. Apical abdominal segments not so retractile ; 

abdomen generally with six ( 5 ) or seven ( S ) 
visible segments ; wings when at rest with 
or without a longitudinal fold. 

a. Hairs not plumose or branched ; basal joint 

of posterior tarsi not dilated. 
a'. Wings when at rest without a longitu- 
dinal fold. 
a'. Petiole of abdomen with one or more 

scales or nodes : species social HETEROGYNA. 

b'. Petiole of abdomen simple : species 

solitary FOSSORES. 

b'. Wings when at rest with a longitudinal 

fold DIPLOPTERA. 

b. Hairs of the thorax plumose or branched ; 

basal joint of posterior tarsi more or less 

dUated ANTHOPHILA. 

The present volume takes in only the Fossores, Diploptera, and 
Anthophila. 

Key to the Families of the Fossores. 

A. Posterior lateral angles of pronotum produced 

back to the base of the wings. 

a. A deep constriction between 1st and 2nd 

ventral segments of abdomen. 
a'. Intermediate coxae contiguous : $ apterous. Mutillidae. 
b'. Intermediate coxae widely separated : 5 

winged Scoliidae. 

b. No constriction between 1st and 2nd ventral 

segments of abdomen. 
a'. Posterior legs short, not reaching much 
beyond apex of abdomen. 
«-. Eyes emarginate on inner side : $ 

winged *Sapygid<s. 

b-. Eyes not emarginate on inner side : $ 

apterous Thynnidae. 

b'. Posterior legs long, reaching well beyond 
apex of abdomen ; eyes not emarginate on 
inner side Pompilidae. 

B. Posterior lateral angles of pronotum not pro- 

duced back to base of the wings; pro- 
notum often forming a mere collar Sphegidae. 



Not known to occur in India. 



XU INTEODVCTION. 

Key to the Families of the Diploptera. 

A. Intel-mediate legs armed with one tibial 

ealcar ; claws of tarsi bifid or dentate : species 

solitary Eumenidae. 

B. Intermediate legs armed with two tibial cal- 

caria ; claws of tarsi simple : species social . Vespidae. 

Key to the Families of the Anthophila. 

A. Tongue short, obtuse, emarginate or bitid at 

apex Colletidae. 

B. Tongue short and acute, or long (sometimes 

very long) and acute, never emarginate .... Apidae. 

The arrangement o£ the Hymenoptera in this volume, so far 
as the primary divisions go, is based on the classification adopted 
by Dr. D. Sharp in the Cambridge Natural History volume on 
Peripatus, Myriapods, and Insects. In the divisions of the 
Aculeate section of the suborder Petiolata I have followed, Avith 
certain modifications, the arrangement given in Mr. E. Saunders' 
valuable work on the Hymenoptera Aculeata of the British 
Islands. With regard to the Anthojihila, I agree with Mr. 
Saunders that the distinction between the bees with obtuse 
emarginate tongues and the bees with acute non-emarginate or 
simple tongues is of greater importance than the distinction 
between the usually accepted divisions of the tribe, Andrenidce 
and Apidce. On the other hand, I have preferred to place the 
whole of the bees with acute tongues under the family Ajndce, as 
there seems to me no choice between this and dividing them 
into several families or subfamilies, as proposed by Schraiedeknecht, 
Dalla Torre, and others. 

The present volume appears under the disadvantage of being 
the first attempt at describing the Wasps and Bees of India 
as a whole ; no complete list even has hitherto been published, 
nor have the Hymenoptera received nearly as much attention 
from Indian naturalists as the Lepidoptei-a. Whilst, therefore, 
it may be hoped that this book will direct the attention of ob- 
servers and collectors in India to a most interesting though 
somewhat neglected order of insects, and that it will facilitate the 
identification of the species which occur, it must be remembered 
that not only is our general knowledge of the Indian Hymeno- 
ptera very incomplete, but our information as to the distribution 
of the species hitherto recorded is singularly imperfect. For 
many of the species described in the following pages no more 
exact locality is known than " India." Some species to which an 
Indian origin was erroneously assigned by the older writers are 
omitted in the present work, and it is probable that a few more 



INTRODUCTION'. Xlll 

here included may not oceui" within the area now under British 
rule, but the majority of the forms recorded as Indian have 
doubtless been obtained from some part of India, Ceylon, or 
Burma, and it is to be hoped that all these will be rediscovered 
and the area they inhabit precisely determined. 

The few species of which I have been unable to examine 
specimens are distinguished by an asterisk prefixed to the serial 
number, thus *960. 

For material I have had my own large collections, made partly 
in the North-West Provinces, and during one season in Sikhim, but 
chiefly during the last twelve years in Burma and Tenasserim. 

I have to thank the Authorities of the British Museum for 
free access to the rich collections contained in the Natural 
History Museum at South Kensington. To Dr. P. Magretti, 
of Milan, Dr. R. Gestro, of the Museo Civico, Genoa, and 
Mons. E. Andre, of Gray, Haute-Saone, France, my warmest 
acknowledgments are due for the generous loan of many types 
and specimens. Above all, however, I am indebted to Mr. G. A. 
James Bothney, who very generously placed at my disposal the 
whole of his large and varied collection made during several years' 
residence in Bengal and the North- West Provinces of India. I 
have to thank also Miss A. Brook, Col. Yerbury, Mr. F. Moller, 
Mr. E. E. Green, Mr. W. D. Cumming, Mr. T. A. Hauxwell, 
Mr. A. Weston, and other friends, for very kindly sending to me 
collections of Hyraenoptei-a from various parts of India, Burma, 
and Ceylon.

Tetbb fossores. 

Family MUTILLID^. 

The insects beloaging to this family have been called " Solitary- 
Ants," With the true ants, however, they have no very close 
affinity, but belong to the Fossores. The sexes, J and $ , are 
solitary ; there are no neuters. The 6 is winged ; the pronotum 
is produced back at its lateral angles to the base of the wings ; 
the fore wing has at least one closed cubital cell ; the 1st discoidal 
cell is always shorter than the 1st submedial cell, and the apex of 
the abdomen is armed with one or more spines or blunt teeth. 
The 2 is apterous, has the legs stout, fitted for digging ; the 
tihiae spinose, the tarsi ciliated, the basal joint of the latter cylin- 
drical and not pubescent on the inside. 

Key to the Genera, 

a. Abdomen in J and J with deep con- 

strictions between 1st and 2nd, and 2nd 

and 3rd segments 1. Apterogyna, p. 1. 

b. Abdomen in $ and (^ with no such con- 

striction, or if constricted the constric- 
tion only between the 1st and 2nd 
segments 2. Mutilla, p. 2.

5 . Head, thorax, and abdomen very coarsely punctured, the 
punctures running into longitudinal coarse striae on the posterior 
portion of the pronotum and on the abdomen. Black, the 
antennae, the vertex and front of the head, the occiput, thorax, 
and 1st abdominal segment red ; the legs obscurely dark chestnut- 
red ; the whole head, thorax, and abdomen covered with glistening 
silvery white hairs. 

S . Similar in colour, with similar pubescence, but the head 
nearly black ; the antennae longer, more filiform, and darker ; the 
pubescence on the apical segments of the abdomen more dense ; 
wings hyaline, lightly fuscous, with a brownish tint.

$ . Head orbicular, sometimes subquadrate ; eyes generally 
small and round; ocelli absent; antennae subfiliform, rarely 
setaceous, inserted low down just above the very short clypeus, 
their bases moderately wide apart ; clypeus generally small ; man- 
dibles unidentate as a rule ; thorax more or less rectangular, or 
quadrate, sometimes oval, occasionally much narrowed and com- 
pressed anteriorly or posteriorly ; legs short, robust, spinose ; 
abdomen ovate, 1st segment subpyriform, occasionally narrowed 
and petiolate, furnished beneath with a carina, which is occa- 
sionally, but vei'y rarely, absent ; anal segment with an elongate 
acute sting often exserted. 



S . Head transverse, compressed, sometimes orbicular or sub- 
triangular ; eyes generally more or less emarginate ou the inside, 
in some species ovate or round ; ocelli three, placed in a triangle 
on the vertex ; mandibles arcuate, generally tridentate at apex ; 
thorax short, massive ; tegul* usually large, sometimes remarkably 
so. Wings broad and ample, the fore wing with three, in some 
species only two, cubital cells ; the 2nd and 3rd each receive a 
recurrent nervure ; when only two cubital cells are present, the 
2ud recurrent nervure is obsolete. Legs long and pubescent. 
Abdomen ovate, generally strongly curved downwards towards 
apex, the apex armed Avitli blunt teeth or spines; the 1st segment 
sometimes petiolate.

52 THYNNID^. 



Family THYNNID^. 

The insects belonging to the typical genus Thynnus are chiefly 
Australian, none being found within our limits. The males of all 
the Thiinnida' are winged, the females apterous. Two Indian 
genera, MetJwca and Isivara, are related to Thynmia and are classed 
generally in the family TJn/nnida;. Iswara is also allied in form 
and in the venation of the wings to Myzlne, a genus of i\\e Scolnda>,. 

Head in female small, in male the M'idth of the thorax ; thorax 
in female subrectangular, constricted posteriorly, in male oval, the 
pronotum reaching back to the base of the wings ; abdomen more 
or less massive, the anal segment in the male of the two genera 
found in India with an up-curved spine.

Family POMPILID^. 

Possorial and predatorial wasps of very varying size, containing 
some very small species as well as some of the largest forms 
among the Hymenoptera. 

Head more or less lenticular in shape. Prothorax of variable 
size and length, the pronotum, however, always reaching back to 
the base of the wings. Wings generally long and ample, in one 
genus only {Parapom-pilus*) extraordinarily short ; fore wing with 
one radial and txvo or tliree complete cubital cells f. When t\\ o 
cubital cells only are present, the 2ud receives both the recurrent 
nervures ; when there are three cubital cells, the 2nd receives the 
1st, and the 3rd the 2nd recurrent nervure. Legs long, reaching 
well beyond the apex of the abdomen ; armature of the legs 
variable, dependent on fimction. Abdomen pseudosessile, never 
actually petiolate as in some of the Sphegidce., but the basal seg- 
ment of the abdomen at its attachment to the median segment is 
often attenuated. 

The difference between the sexes is well marked, sometimes it is 
very striking. The males are, as a rule, smaller, aud more 
slenderly built ; the antennae are porrect ; in the females these 
organs, after death, are convolute at apex J. The apical three 
abdominal segments in the male are essentially different from those 
in the female. If the median segment is not included, the female 
has six, the male seven visible abdominal segments. 



* Not known to occur in India. 

t In the genus Ceropales, by the extension of the cubital nervure to the 
margin of the wing, a 4th complete cubital cell is formed, but the character is 
not constant. 

\ Except in the genus Cer&pales, the females of which have porrect antennce. 



MACROMERIS. 103 

The species of Pompilido' generally make their nests in the 
ground, iu burrows dug by the female, or in holes in trees, chinks 
in the floors or walls of wooden houses, or in the hollows of 
bamboos. Ar/euia, Pseudagenia, Paragenia, and, I suspect, Macro- 
meris too, construct little earthen shells for nests. As a rule, 
spiders are provided as food for the future brood, but one or two 
species are \ re:latorial on crickets (Gryllidce), cockroaches (Blatta), 
and Coleoptera. No parasitic forms are known among the 
Pompilidce.

The habits of the species belonging to this genus are almost 
unknown. Once I observed a female carrying some large hairy 
spiders (Heteropoda venatoria) to a chink in a deserted wooden 
house, in the forests in Tenasserim, and there is no doubt she was 
storing these as food for her future progeny. 

Only three species are known, of which, so far as I know, only 
one, M. violacea.. LepeL, is found within our limits. Smith, however 
{loc. cit.), gives M. splendida as coming from India too, but there 
is no specimen of it from India in the British Museum collec- 
tion, nor have I seen it in any other collection from India, Burma, 
Tenasserim, or Ceylon. It, as well as the third species recently 
described by me (Jour. Linn. Soc. 1896, p. 438), may occtir ; I give, 
therefore, a key to easily discriminate the three species.

I have not seen either this species or P. concolor, Sauss., which 
seems closely allied to it. Both, so far as their description o-oes, 
seem to be very similar to P. pcdunculata, Smith. It is possible 
that all three are forms of one species.

Form of the clypeus, pronotura, and median segment very 
variable : wings long and ample, fore wing with 3 cubital cells, the 
3rd cubital cell measured on the cubital nervure as long as or 
longer than the 2nd cubital cell, the latter receives the 1st 
recurrent nervure after the middle of the cell, and in one group 
(Mygnimia, Smith) at the extreme apex, interstitial with the 2nd 
transverse cubital nervure ; the 3rd cubital cell receives the 2nd 



SALIUS. 123 

recurrent nervure before the middle ; the basal or transverse 
medial nervure takes its rise before the apex of the 1st svibmedial 
cell, the cubital nervure stops short of the margin of the wing, and 
the discoidal nervure reaches, ordinarily, up to it ; in many species 
a hyaline discoidal spot is present, conspicuous when the wing is 
of a dark shade ; in the hind wing the cubital nervure originates, 
as a rule, just before the apex of the anal cell. Legs very long, the 
apex of the posterior tibia, when the legs are stretched, reaching 
well beyond the apex of the abdomen ( $ ) ; the armature of the 
legs varies, but generally is well developed ; the anterior tarsi are 
ciliated on the outside, the posterior tibiae are angular or sub- 
angular, never quite cylindrical, in most of the species grooved, 
spined, and serrated, very often strongly so ; claws with one or 
more erect teeth on their under margins, or bifid. Abdomen pseudo- 
sessile, the 2nd ventral segment with a transverse impressed line 
or groove, as a rule well-marked in the female, nearly obsolete 
and difficult of detection in the male. 

Very little is known of the habits of the species belonging to this 
genus, which contains some of the largest forms of Hymeuoptera 
in the World. Some, like Pompilus, make their nests in the ground, 
digging these themselves, and providing spiders as food for their 
broods ; others make use of holes in trees, and provision their 
nests with cockroaches, or, like the Larridce, with crickets.

which affords a good example of the impossibility of separating 
the genus Mygnimia, Shuck. & Smith = Bemij)e2}sis, Dahlbom, from 
Priocnetnis, Schiodte. Out of a series of over 70 specimens that 
I have examined, 40 have the Mygnimia venation, and more than 
'60 that of the genus Priocnemis ; but then all the latter have the 
bidentate claws to the tarsic haracteristic of Mygnimia, and are 
absolutely identical in sculpture and colouring with the former.

length of the 3rd ; the second transverse cubital nervure is 
sharply elbowed at the top, making the cellule much narrower 
at the top than at the bottom, where it is rounded broadly at the 
apex, instead of acutely angled as in rothnei/i, while the cubital 
nervure terminates completely there ; the 1st recurrent ne-'-'ure 
is received a very little beyond the middle, the 2nd at a less 
distance from the transverse cubital nervure than is the 1st ; the 
radial nervure becomes elbowed about the basal third (and also 
more sharply), while in rothneyi it turns up at the middle of the 
cellule. S. cotesi also is larger, being 13 mm. in length. The 
long spur of the hind tibiae does not reach the middle of the 
metatarsus ; the tibial spines are shorter and fewer."

148 POMPILID^. 

Type, P. fnsciis, Linnaeus. 

Kawje. Both hemispheres. 

Form of the clypeus, pronotuni, and median segment very 
variable. Fore A^-ing with three cubital cells, the 2ud and 3rd as 
a rule subequal, both cubital and discoidal nervures stopping short 
of the margin of the wing ; anterior tibiae and tarsi ciliated on the 
outside, intermediate and posterior tibiae and tarsi spinose, the 
tibia; never serrate, claws unidentate at base below, sometimes 
bifid. Nesting in the ground, in burroAvs made by the female ; 
the usual provision for the larvje consists of spiders, but I have 
seen one species carrying small cockroaches to its nest.

$ . This species is identical in form, sculpture, and markings 
with P. pedestris, Smith, but I keep it apart, as the 3rd cubital cell 
is petiolate, not subtriangular as in pedestris. I have also carefully 
examined the types * of P. vischnu. Cam., in Mr. Eothney's 
collection, and they as well as the rest of the specimens labelled 
P. vischnu are, so far as I can make out, nothing more than rather 
small males of P. incognitus. All have the 3rd cubital cell in the 
fore wing petiolate f.

* Two specimens, both males, are labelled " P. vischnu. Cam., Type" m what 
I believe is Mr. Cameron's handwriting. 

t Mr. Cameron has made some mistake in his descriptions of Pompilus 
vivax and Pompilus vischnu. Of the former he says (loc. cii.), " Second cubital 
cell petiolate," whereas it is the 3rd cubital cell which is petiolate; vide also the 
Plate figure, which is correct. Of P. vischnu he says, "Identical in colour 
of the body and wings to P. vivax, differing in the 2ud cubital cell not being 
petiolate " ! The types and all the specimens labelled P. vischnu in Mr. Eothney's 
collection hare the 3rd {not 2nd) cubital cell petiolate.

sides and widely emarginate in the middle ; the pronotum is longer 
with a more gradual slope anteriorly, the median segment is 
slightly longer, and the abdomen more sessile aud thicker at base. 
In colour P. rothneyi has the flagellum of the antennae below and 
the posterior femora and tibiae black instead of red, and there is 
no yellow fascia on the posterior margin of the pronotum. The 
two species e.xist together, but, so far as I have been able to 
observe, P. rothnmji frequents the thickest forest, while pedestris is 
to be found in the open and occasionally comes into houses.

Type, A. unicolor^ Spin. 
Range. Both hemispheres. 

Head subglobose, about as wide as the thorax ; ocelli in a 
triangle on the vertex; antennae inserted about the 
middle of the face, not so long as the head and 
thorax united, fihforra, slightly curved after death 
in the female; labrum concealed, clypeus subporrect; 
thorax convex above ; scutellum minute, depressed 
below the level of the mesonotum ; for the rest, the 
characters are those of Pompilus, except that in the 
fore wing there are only two cubital cells and 
that the anterior tarsi are not ciliated. The 2nd 
Fie. 39. cubital cell receives both recurrent nervures. 

Aporus cotesi, JSote. — Kohl (loc. cit.) considers that the species 

$. T- of this genus are derived directly from Pompihis 

by the loss, in the fore wing, of the 2nd trans- 
verse cubital nervure, and that Aponts cannot be kept distinct 
from Pompilus. It is quite probable that the one genus has 
been evolved from the other in the ^^■ay indicated bv Kohl : 
still, as the distinctive character of two cubital cells in the 
fore wing seems to be constant, and generic distinction is a 
matter of convenience, I see no reason w hy Ajiorus should not be 
kept separate from Poiiqjilvs, so long as it is ])laced next to that 
genus and the relationship between the two is clearly understood.

Family SPHEGID^. 

The pronotum transverse, its lateral angles not prolonged back 
to the base of the wiugs. 

The above is the sole constant character that separates this 
rather heterogeneous family from the other families of the Fossorial 
Hymenoptera. 

In a limited fauna as that of G-reat Britain, for instance, it is 
possible to divide the Fossores into fairly well-marked groups, 
which can be conveniently regarded as forming families or sub- 
families ; but all such limitations break down when exotic species 
are taken into consideration. It is therefore now generally held 
that the burrowing wasps with short prothoraces form only one 
family, containing genera, many of which have a tendency to form 
natural groups, while others stand more or less isolated.

Range. Both hemispheres. 

Head wider than the thorax ; mandibles with a narrow incision 
on their outer margin close to the middle ; the inner margin 
bidentate ; clypeus and face always densely pilose or pubescent ; 

antennae stout, and generally shorter 
than in the genus Tachysphex ; eyes, 
especially in the c? , strongly con- 
vergent towards the vertex, but 
never quite meeting as in the 6 of 
Astata • the ocelli are placed on a 
convexity on the front, the anterior 
ocellus round, the posterior elongate, 
almost reniform, slanting, flat, and 
less distinct ; pronotum depressed 
beneath the level of the mesonotum ; 
pygidial area distinct, in the $ triangular, in the c? generally 
trapezium-shaped, but in both always pubescent, in the 5 set 
with dense, short, stiff hairs, in the c? with sparser pubescence. 
AVings stout, ample ; fore wing with one radial and three cubital 
cells, the radial cell lengthened and acute at apex, and only feebly 
truncate, showing in consequence only an indistinct appendicular 
cell. Legs — the tibiae and tarsi of all the legs more or less spinose, 
the tarsal combs altogether much shorter and stouter than in 
Tachysphex. 

Tachytes contains some of the most beautiful of the species of 
sand-wasps. Many of the Oriental forms are black, or black and 
red, richly decked -with golden or silvery pubescence and pile. All 
the Indian species whose habits I have been able to investigate 
nest in the ground, and store their nests with the larvae of 
Orthoptera.

It is with some doubt that I identify one specimen contained 
in the collection at South Kensington with this species. Of the 
4 specimens labelled Larrada maura in the Museum, three are 
without doubt Notogonia subtessellata, Smith, having the prouotum 
depressed below the level of the mesonotum, the pygidial area 
pubescent, and the claws of the tarsi rather long ; the 4th is a true 
Larra, with the pronotum not or scarcely depressed, the pygidial 
area bare and punctured, and claws of the tarsi short. It 
resembles Larra glabrata, Smith, but is quite distinct from it, and 
possibly is the species described by Fabricius.

Head a little wider than the thorax ; mandibles with no excision 
on their outer margins, the inner margin bidentate close to the 
base; face more or less richly pubescent; the convergence of 
the eyes as in the genus Notogonia ; the front puckered along 
the inner orbits and broadly furrowed ; ocelli — the anterior 
ocellus round, of ordinary form, complete, the hinder two 
lengthened, flat, hardly observable, and lying considerably to the 
rear of the anterior one ; the pronotum depressed beneath the 
level of the mesonotura, its posterior margin not transverse, but 
coming to a point in the middle ; wings — fore ^^^ng with one radial 
and three cubital cells, of the same form and shape as those 
in the genus Larra ; legs, on the whole, a little longer than in 
Larra, and nearly as long as in Notogonia ; the armature of the 
legs in general well-developed ; intermediate tibise with one apical 
spur ; claws lengthened ; the median segment and the 2nd ventral 
segment similar to those of Larra ; the anal segment with a

nest-holes in the ground, providing as food for their future 
brood Orthopterous insects of various kinds. L. aurata may, 
like Notogonia suhtcssellata, commonly be seen struggling with a 
paralyzed cricket three or four times its own weight and size.

sixth uudescribed form from Natal, received in the Museum in

pinned above a cricket, as if in the act of carr5'ing it, I presume it 
was so engaged at the time of capture. It is highly probable 
that all the species of this genus are, like the rest of the closely

Type, M. bicohr, Jur. 

Range. Palsearctic, Neotropical, and Oriental regions. 
All the known species are of small size, 3-10 mm. in length, 

and have the general facies of 
Larra and allied genera. The 
mandibles with an incision on 
the outer margin close to the 
middle, the inner margin not 
toothed, the apex simple ; base 
of the antennae low down on the 
front ; the flagellum filiform ; eyes 
very slightly convergent towards 
the vertex ; ocelli complete, round, 
pj„ 53^ and placed in a somewhat long 

Miscophus rothneyi, 2 • t- triangle just below the vertex ; 

vertex broad, transverse; pronotum 
scarcely at all depressed beneath the level of the mesonotum ; 
median segment as long as the mesonotum or slightly longer, 
the apex more or less truncate; legs longish, stout, the inter- 
mediate tibiae with two apical spines. Wings ample, the fore 
\\ing with one radial and two cubital cells, the radial cell 
not appendiculate ; the 1st cubital cell large, receiving the 1st 
recurrent nervure near the apex, the 2ud cubital cell triangular, 
petiolate, receiving the 2nd recurrent nervure almost at the apex.

area, conical. 

Only one species is, as yet, known from India : it is in the 
collection of Mr. Gr. A. James-Eothney, and was placed in the 
collection above the \ohe\ Notogo7iia pulchrijiennis^hy M-V.Ca.mQvon 
(probably overlooked). The European species are said to provision 
their nests with spiders.

The species of this genus construct their nests of clay, making 
delicate little shells, granular on the outside and somewhat 
lengthened in shape ; these they store with minute spiders as 
food for their larvae. Home found their nests built on straws ; I 
have only once found a nest so built. 

Trypoxylon pileatum, which is yerj common in Burma, usually 
selects the folds of an unopened newspaper lying on the table in 
the verandah, or the ends of a closed book, on which to construct its 
fragile little nests. I have also seen T. hicolor carrying clay to an 
old nail- or screw-hole in the walls or doors of the house.

Range. Both hemispheres. 

Head flat ; eyes with their inner orbits either parallel or cou- 
veri^ent towards the vertex of the head, never divergent; antennae 
filiform, short, and somewhat stout in proportion in some species ; 
front often with carina) extending upwards from 
the base of the antennae ; clypeus shaped some- 
what like a ploughshare ; the medial carina 
generally large, ending in a tooth or bifurcating 
towards the apex ; mandibles sickle-shaped, simple 
in the female, dentate in the male. Prothorax 
elongate, the posterior middle portion raised, 
the raised portion narrower than the mesonotuin, 
the posterior angles at a distance from the base 
of the wings; mesonotam broad, marked with 
longitudinally impressed furrows ; median seg- 
ment flat above, slightly narrowed towards the 
Fig. 67. apex, and roundly truncate posteriorly, aboAe 

comp^^m? 1. ^^'th several longitudinal carinse, the space 
'" between which is more or less closely trans- 
versely striate, the posterior lateral angles of the segment almost 
always with one or more erect tubercles ; legs long, stout, the 
tibise and tarsi slightly spinose, the intermediate cox* separated 
by a more or less narrow plate which forks posteriorly, intermediate 
tibiffi with two apical spines, claws toothed. Wings rather short ; 
fore wing with one radial and two or three cubital cells, the forms 
with two cubital cells plainly derived from the form with three 
cubital cells by the obliteration of the 1st transverse cubital 
nervure, the beginning of which can be often traced in various 
two-celled species; when three cubital cells are present, the 1st 
and 3rd are subequal, each receiving a recurrent nervure, the 2nd 
small, square, or broadly rectangular. Abdomen pseudo-petiolate, 
the basal segment never narrowed into an actual petiole as in 
Sphea\ generally roundly steep at base, the apex of the 1st segment 
in most cases constricted ; the apical segments compressed, some- 
times extraordinarily so, the 2nd ventral segment produced more 
or less at a right angle to the plane of the 1st, the joint between 
the median segment and the abdomen exceedingly flexible, the 
insect being able to double its abdomen beneath the thorax and 
pi-otrude its sting between the fore legs in front. 

These beautiful insects are predatory on cochroaches {Blatta). 
In Burma I have frequently seen these wasps come into the house 
and search for their prey under boxes and f urnitun;. In the forest 
once I watched a rather large specimen of A. compressa., Fabr.,

by a sting or dazed with fear, and was beiug half dragged by an

rather widely separated, inserted at the base of the clypeus, 
transverse ; labriim small and triangular ; mandibles stout, their 
apex dentate ; thorax broadly oval ; the mesonotum and median 
segment strongly convex, gibbous ; wings with one radial and two 
cubital cells, the radial and 1st cubital cells subequal, but the

The only Indian species at present known comes from an 
elevation of 7000 ft. in the Himalayas, and nothing is on record 
about its habits, which, however, probably resemble those of the 
European species. The latter nest in holes in old posts and rails, 
and provision their larvae with Aphides.

cell petiolated ; the third oblique, of nearly equal width ; the 
first recurrent nervure received by the first submarginal cell 
near its apex ; the second recurrent nervure entering the second 
submarginal cell near its apex ; the legs stout ; the anterior 
tarsi ciliated outside, the intermediate and posterior tibiae spinose ; 
the claws simple, having a pulvillus in their fork. Abdomen ovato- 
conic, truncated at the base, the apex acute." — Smith. 

To Mr. Smith's accurate and full description I have to add an 
important particular — a detail of character which seems to have 
been overlooked. The posterior coxie are armed at their apex., in 
both 2 ff''*^'^ c? , with a long acute spine pointing hacTcwards. In the 
type of the genus, the posterior coxa of which is figured above, 
this is very prominent; but in the Indian species described below 
the spine is reduced to an obscure tubercle on the underside of 
the coxa. 

H. melanopyrus, on which this genus was founded, is from the 




HELIOEYCTBS. — GORYTES. 271 

Gambia district in West Africa. From West Africa also there is 
in the collection of the British Museum one specimen of a third 
species of this genus, possessing the characters as given by Smith, 
and also the coxal spines. In the collection it stands as Para- 
nvsson ahdominaJe, Gruerin, and answers well enough to Gueriu's 
brief description so far as this goes. The genus Parani/sson was 
indicated (scarcely diagnosed) by Guerin in his ' Iconographie du 
Eegne Animal de G. Cuvier : lusectes,' p. 441; but the description 
was so slight and incomplete that in my opinion Smith's name 
for the genus must stand. I mav further note that Haudlirsch 
(Sitzungsb. Akad. Wiss. Wieu, 1887, p. 282) unites Paranysson 
with Nysson.

head, thorax, and abdomen very minutely punctured, with a very 
fine short erect hair springing from each puncture ; clypeus much 
broader than high, slightly convex, pointed laterally, widely eraar- 
giuate in the middle anteriorly ; the enclosed space at the base 
of the median segment semicircular, with a short medial longi- 
tudinal furrow continued down the posterior truncated face of the 
segment to the apex. Rufo-fulvous, the base of the mandibles, the 
labrum, clypeus, antennae in front, cheeks, pronotum, postscu- 
tellum, an arched stripe on the median segment, a large rounded 
lateral spot on the 2nd, and an elongate lateral spot at the base 
of the 3rd abdominal segment yellow ; legs variegated with yellow ; 
wings deep flavo- or fulvo-hyaline, with a subapical fuscous cloud 
on the fore wing.

Note. — Handlirsch (Sitzungsb. Akad. Wiss. Wien, ci, 1892,

less resembling S. prismaticus, Smith. One of these is given from 
the Andamans, two or three others are stated to occur in the 
Oriental region. I do not know of the latter having been found 
within our limits. I append, however, short descriptions, taken 
from Handlirsch's work.

male with the joints of the apical half

"^ two small, the interior long and very 

acute ; labrum exserted, very long and convex, pointed, with the 
mandibles crossing in X-shape over or behind it. Thorax broad, 
slightly vertically flattened ; pronotum small, depressed beneath the 
level of the mesonotum ; median segment short, roundly truncate 
posteriorly : wings somewhat short, radial cell of fore wing long and 
narrow ; three cubital cells, the 1st forming a long triangle, equal 
to or longer than the 2nd and 3rd united, 2ud and 3rd subequal in 
length, the latter narrower than the 2nd, which latter receives both 
the recurrent nervures. Legs fairly stout, spiuose ; 1st joint of the 
anterior tarsi always ciliated, cihas often of great length ; inter- 
mediate femora in male generally dentate beneath ; intermediate 
tibiae with a long apical spine anteriorly and a short one posteriorly ; 
claws simple. Abdomen massive, broad, never petiolate, the 1st 
segment as broad as the 2nd and steep at base, the apical segment 
laterally often toothed or with a sinuate margin, the apex rounded, 
truncate or incised ; one or more of the ventral segments, in a 
large majority of species, furnished with carinae or tubercles, 
especially in the male. General colour of the insects black or ferru- 
ginous, with sinuate lacteous or yellow bands on the abdomen. 

The habits of these insects are well known ; they nest in sandy 
banks, some of the Indian species (e. g. B.fossorius) gregariously, 
digging their own tunnels and using their powerful ciliated anterior 
legs, in the manner of a dog digging. The food furnished for the 
larvae is always, so far as I know, various species of Diptera, and 
some of the Indian species certainly do not close their nests, but 
frequently supply their larvae with fresh food.

Head as wide as the thorax or wider, broader than long, 
subquadi-ate in some species, seen fi'om above ; ocelh in a triangle 
on the vertex ; eyes ovate, not reniform ; antenna? very slightly 

clavate, inserted about the middle 
of the face or a little higher ; 
mandibles stout, simple, unideutate 
or bidentate ; thorax ovate, pro- 
notum transverse; median segment 
roundly truncate, always with a 
larger or smaller triangular or 
cordate space at the base enclosed 
by convergent furrows ; legs stout, 
and in both sexes strongly spinose, 
more spinose in tlie $ . than in the 
-Cercerisvigilans, 5- t- c? ; anterior tarsi ciliated; inter- 
mediate tibiae with one apical spur ; 
posterior tibiae with two. Wings long, ample ; fore wing with one 
radial and three cubital cells, the radial cell oblong, the 1st cubital 
cell longer than the 2nd and 3rd united, the 2nd triangular, 
petiolate, receiving the 1st x'ecurrent nervure about the middle, 
the 3rd cubital cell receives the 2nd recurrent nervure near its 
base. Abdomen oblong, subpetiolate, the petiole formed by the 
narrowing of the 1st segment, which is sometimes subglobular ; 
the apical margins of the basal live ( ? ), or basal six ( cJ ) segments 
strongly constricted, pygidial area with three planes bordered by 
carinae, the three planes always more or less rugose. 

The fossorial wasps of this genus are predatory on beetles ; the 
Indian species I have had an opportunity of observing always 
store Ghrysomelidce in their nests. C. elizabethce I found carrying 
Downesia brettiughami to her nest. The nests that I have seen have 
always been dug in level ground, never on a bank-side, and the 
tunnels leading to them were from 6 to 12 inches deep.

abdomen pseudosessile, subpetiolate or petiolate ; in some species 

the basal abdominal segment is closely applied to the mediau 

segment, almost truncate at base, in others it is subclavate, or 

again distinctly petiolate, nodose at the apex. 

Very little is known of the habits of the Oriental forms of this 
genus. Some of the European species are known to make their 
burrows in bramble-sticks and decayed wood, and to store Aphidttt 
as food for their larvae. In Burma I once noticed 0. opife.v 
carrying off Aphidce from a rose-tree in my garden ; but I could 
not trace her to her nest.

Most if not all of the species of this genus make little rounded 
cells of clay for nests, provisioning these with caterpillars as food 
for their larvae. Eumenes conica, flavopicta, and arcuata are very 
bold insects, coming into houses and constructing their nests on 
the walls, against the punkah, on the legs and bottom of chairs, 
tables, &c., and permitting close inspection of their nest-building 
operations without showing any alarm or irritation.

little round shells of clay for nests, and provisioning these with 
caterpillars. Occasionally an already existing cavity is made use 
of, and the aperture closed with a clay lid.

parts also variable : the antennae in the majority of species rather 
short, filiform, the apical joints in the male with a small hook, or 
spirally rolled ; mandibles blunt with blunt teeth, never long as 
in Eumenes ; labial palpi stout, 4-jointed, and covered with stiff 
hairs ; maxillary palpi (>-jointed, diminishing in length to the apical 
joint, Avhich, however, is sometimes longer than the 5th joint, the 
apical three joints united, distinctly longer than the 3rd. Thorax 
rounded or truncate both anteriorly and posteriorly, in a few 
species emarginate posteriorly ; legs short, somewhat feeble and 
slender, intermediate tibite with one apical spine ; claws dentate. 
Wings : in the fore wing the form and proportions of the radial 
and cubital cells are variable; in general, however, the radial cell 
is widely subtriangular, the apex acute, or slightly truncate and 
appendiculate ; three cubital cells, the 2ud receiving both recur- 
rent nervures. Abdomen of variable shape, the basal segment 
often narrowed, but never fashioned into a long petiole as in 
Eumenes, always more or less covering over the base of the 2nd 
segment. 

The genera Rhynehium and Odi/nerus are only clearly separable 
by an examination of the mouth-parts, as noted in the key to the 
genera. Externally the tMO genera resemble each other and grade 
one into the other astonishingly. Roughly, however, the species 
of lihj/ncMum are larger, heavier built insects than the species of 
Odynerus. Both genera can at once be distinguished from Eumenes 
by the form of the basal abdominal segment, which is never 
narrowed into an elongate petiole, but, though often constricted and 
narrower than the 2nd segment, always receives and more or less 
covers over the base of the latter. 

The species of Odyneri make sometimes little thin clay shells 
for nests, but more often make use of crevices and holes for their 
nurseries, storing as food for their larvae the caterpillars of various 
species of small moths. I have never found them attacking or 
storing spiders or other prey.
