742 ASILIDtE 



but on the upper part between tbe neck and tlie vertex are numerous long 

 stronger brownish yellow hairs ; frons shining black, wider than the face but 

 hardly widening on its upper part, deeply sunk and apparently bare ; ocellar 

 space very much elevated and bearing some very minute brownish yellow 

 bristles behind and above • antennal prominence broad but rather slight, and 

 bearing some short blackish bristly hairs on its sides ; collar shining black 

 and bearing an inconspicuous circlet of about eight longer thin pale yellow 

 hairs on the upper part, while behind these are some sparse shorter yellow 

 hairs, and much more numerous hairs on the sides, in addition to some whitish 

 longer hairs below on the prothorax. Proboscis shining black, with the bush of 

 hairs above near the tip long, rather dense, and obscurely whitish, Avhile those 

 beneath near the base are few in number ; palpi shining black, hardly half as 

 long as the proboscis, and bearing on the end part numerous long porrected 

 brownish white bristly hairs. Antennae (fig 398) black, moderately dulled on 

 the two basal joints by brownish orange dust ; basal joint barely one and a 

 half times as long as the second joint, and bearing some short depressed 

 black bristles on its upper part and a few longer moi'e erect ones beneath ; 

 second joint more cup-shaped and with the bristles beneath shorter ; third 

 joint barely as long as the two basal joints together, and with only indications 

 of tiny dorsal bristles before the middle ; style almost as thick as the third 

 joint and more than a quarter its length. 



Thorax mainly covered with brownish yellow tomentum and pubescence, 

 but with two rather narrow moderately shining black stripes down the disc, 

 which are separated by more than their own width, and which die out 

 considerably before the hindmargin, while broader blackish side lines begin 

 considerably before the suture and extend almost to the hindmargin, but 

 these side lines are less defined and bear a few short yellow hairs like those 

 on the dusted part of the disc ; the dorsopleural suture and the greater part 

 of the humeral plates are shining black (leaving the upper part rather dusted), 

 but the raised point at the back part of the humeri is shining chestnut. 

 Bristles ; one prtesutural and three' supra-alar, strong, distinct, and brownish 

 orange. Pleurae shining black, but the " shimmer stripes " and the coarse 

 tomentum cover the greater part of them ; the front shimmer stripe is glisten- 

 ing pale yellow all along the top margin of the mesopleuree and broadly down 

 the front of that and of the sternopleur^, and apparently continues all 

 across the front coxae (where it bears rather abundant rather long whitish 

 pubescence) ; the stripe on the back part of the mesopleurae is narrow and 

 less conspicuous but becomes more conspicuous on the small patch just after 

 the lower hind corner of the mesopleurae and down the back part of the 

 sternopleurce ; metapleurse all dulled by brownish yellow dust, bearing on 

 their back part thin pale yellow pubescence and a fan of about four long 

 thin whitish bristly hairs ; hypopleurae all dulled by brownish yellow 

 tomentum ; the tomentum on most of the y)leurc\3 is very coarse (especially on 

 the front part) but scarcely amounts to pubescence (unless on the hind and 

 upper margins of the mesopleurae). Scutellum with but little dust though 

 with rather sparse short yellow hairs and consequently more shining black, 

 and with no distinct marginal fringe ; metanotum dulled by not dense 

 brownish orange dust. 



Abdomen practically unicolorous black and shining though not brilliant, 

 but sometimes the extreme hind corners of the third and fourth segments are 

 indistinctly orange ; a very short sparse adherent yellow pubescence is scattered 

 all over except on a ring at the base of each of the second to fifth segments, 

 and the hindmargin of the basal segment bears at each side a row of about 

 five long whitish bristly hairs. Genitalia with the shining black dorsal plate 

 bearing sparse short yellow pubescence and with each lower end corner 

 produced into an almost pointed short projection, so that the pair of rather 

 thick ovate shining black lamellae between these projections extend out a 

 little farther and bear very short white hairs ; side ventral plates long 

 and triangular, ending in a pair of shining brownish orange processes, 

 while beneath are some more long brownish orange lamellae and some long 

 not at all dense dull orange hairs. 



Legs orange and black ; upper part of the anterior femora broadly black ; 

 apical third of the anterior tibiae indeterminately blackish and this colour
