bristly prashindmarginal liairs and ^vitli about two of this row towards eacli 

 side (but not near tlie sidemargin) forming long yellow bristles ; third 

 segment with a similar fringe but with the yellow bristles weaker and with 

 some of the smaller bristles nearer the middle of the hindmargin also yellow ; 

 fourth segment with a small black better defined fringe and with about four 

 yellow bristles on each side which are smaller than those on the third 

 segment ; fifth segment with a fringe similar to that on the fourth but with 

 fewer yellow bristles ; and sometimes the yellow bristles are altogether 

 missing on the fourth and subsequent segments ; these fringes on the second 

 to fifth segments are placed well away from the actual hindmargin so that 

 the broad hindmarginal hems are quite bare. Belly ashy grey, with a blackish 

 splash on each segment from the third onwards ; when viewed sideways the 

 line of the belly is level for the four basal segments, but the next three 

 segments have their hindmargins tilted so that they project beyond the base 

 of the next segment and each of these segments has distinct sloping black 

 hairs which become longer and more conspicuous at the hindmargins of the 

 sixth and seventh segments, while even the third and fourth segments have a 

 few short inconspicuous sloping black bristly hairs on their discs ; the seg- 

 ments from the fourth onwards diminish in length ; pubescence long 

 straggly thin-haired and whitish from the base to the fifth and sixth or 

 even seventh segments, but bristly and black even before the lobe on the 

 • eighth segment ; eighth segment with its hindmargin produced into a con- 

 spicuous process which has a deep curved emargination at its end so that it 

 has two conspicuous horns or sharp outer angles Avhich bear long black bristly 

 pubescence, and the surface of this lobe which is nearest the belly is shining 

 black and bare but rather rough. Genitalia (fig. 360) comparatively small, 

 shining black ; claspers (when seen sideways) long, rather narrow, and nearly 

 straight, with the upper end angle produced and pointed, but (when seen from 

 above) showing a large dentation about the middle so that they enclose 

 two long scarcely separated ovate spaces from the basal one of which the 

 small upturned almost linear (with rounded tip) pubescent inner lamellae 

 usually protrude ; the claspers bear pale pubescence on the basal half outside 

 and also to a certain extent on the apical half of the inside, but the hairs on 

 the rest are mostly black though with pale hairs intermingled ; lower lamellae 

 about half as long as the claspers, shining black but dusted about the tip 

 and usually bright orange-red at quite the tip, and bearing on the outside 

 some mixed black and yellow moderate bristles and about three (3-6) strong 

 black bristles, but when seen from beneath the lower lamellae tend to 

 approximate at their ends and partially enclose a heart-shaped space in 

 which are some bright shining orange-red processes ; basal ventral plate of 

 the genitalia dusted and bearing numerous moderate black bristles. 



Legs black and reddish orange ; femora black with reddish streaks of 

 varjdng extent and distinctness, as a well-marked specimen has the front 

 femora reddish orange on the upper and postero-dorsal surfaces and on a 

 ring near the tip, and the posterior femora with similar but less definite 

 markings, while an obscurely marked specimen may have the reddish 

 markings so much darkened that only the Y)ra?apical ring can be distinctly 

 traced ; the front tibite may be reddish orange with the tip and an anterior 

 streak (widened at the tip) blackish, the middle tibiae with similar but less 

 definite markings and the blackish anterior streak disconnected Avith the 

 black tip, and the hind tibice with still less definite markings and the anterior 

 streak obscure, or the anterior tibia? may have the dark streaks larger and 

 more complete while the hind tibiie may have the basal two-thirds indistinctly 

 black ; the tarsi are usually reddish orange with the tip of the basal joint 

 darkened and each subse(iuent joint more blackened at and near the tip until 

 the last joint is practically all black, or the tarsi may be blacker on especially 

 the basal joint of the hind pair and on the tips of the other basal joints. 

 I'ubescence (as distinguished from long or strong bristles) mainly pale 

 yellow ; long and whitish on the anterior cox;e, but most abundant on the 

 front pair ; very long beneath the front femora and with a few black hairs 

 near the tip, and moderately long posteriorly but minute and adpressed 

 anteriorly ; also very long but blackish or greyish beneath the front tibiae 

 but mainly minute and adpressed elsewhere and varying in colour except
