Mr. Claude Morley on the Ehopalosomidae. 387 
apically acuminate. Thorax subcylindrical, obsoletely pilose and 
hardly punctate throughout; prothorax normal and extending to 
base of tegulae; mesonotum gradually declived anteriorly, finely 
sulcate above tegulae but with no notauli ; metathorax evenly declived 
with no trace of carinae, its spiracles oblique, impressed and sub- 
linear : mesosternum very short, convex throughout, pilose and not 
laterally sulcate. Scutellum immarginate, subdeplanate, triangular 
and apically obtuse, obsoletely punctate and pilose with its basal 
fovea simple. Abdomen subnitidulous, shagreened and shortly pilose; 
basal segment subsessile, basally half the length of its apical 
breadth, which is hardly half (or in $ a third) of its total length, 
convex and with no sculpture, gradually explanate to near its 
constricted apex with distinct spiracles at its basal third and a 
determinate discal fovea before its apex ; second segment as long as 
the first and about half as broad again, gradually explanate basally 
and not strongly constricted at its apex, with its base both above and 
below longitudinally niultistrigose and thyridii linear; third and 
fourth segments together about as long as second and extremely 
closely connected though not connate, the fourth becoming narrower 
apically with its dorsal margin subemarginate ; fifth as long as 
fourth ; sixth and in ^ seventh much shorter and deflexed; venter 
convex throughout and not plicate, with four well-developed segments 
and two very short ones preceding the (^) stout and black genital 
valvulae, which extend only to the anus, or ($) the elongate 
hypopygium, which extends to anus and covers base of the minute 
terebra. Legs very slemler but not elongate, hind ones of ^ hardly 
extending beyond the abdomen ; anterior trochanters appear uni- 
(though probably no more than telescoped), the hind ones bi-articulate; 
front tibiae hardly longer than the metatarsi, and sparsely spinose 
internally, each with a single elongate and basally sinuate calcar ; 
tarsi long and in slender with the claws small and pectinate, 
basally not lobed though shortly pulvillate in 5 > the four apical 
joints strongly spatuliform and dilated with their apex setiferous on 
either side and base constricted, claws simple and shorter than the 
bilobed pulvilli; posterior femora apically subspinate internally with 
their tibiae very elongately bicalcarate ; front and hind metatarsi 
basally sinuate, the latter with the inner calcar basally strongly 
pectinate in Wings neither broad nor ample, hyaline with the 
stigma narrow, inconspicuous and centrally subconstricted ; all the 
nervures testaceous; upper wing with nervures disposed as in 
Ichneunionidae excepting the extreme pellucescence of the second 
recurrent which is, however, distinctly traceable and the aberrantly 
bifurcate first intercubital or submarginal nervure ; upper basal 
nervure emitted from the median much further from base than the
