9. EPITRIPTUS 689 



hairs down the sides which are more or less Hack on the upper part but 

 quickly become yellow and which form about two irregular rows ; collar 

 dull golden, bearing abundant long pale pubescence and about two stout 

 black or orange bristles on the upper part. Proboscis black as usual, and 

 bearing the usual pubescence ; palpi thin, black, and bearing porrect black 

 bristly hairs with sometimes some pale hairs intermixed. Antennae dull 

 brownish black ; second joint cup-shaped on only its apical half, twice as long 

 as its broadest part ; basal joint bearing short mainly_ yellow bristly hairs 

 above and longer stouter black ones beneath ; second joint with similar but 

 much shorter hairs ; third joint elongate very narrow ovate ; style rather 

 more than half as long as the third joint and not placed at an angle to it, not 

 very thin (except at just the tip) but much thinner than the end of the third 

 antennal joint, and its basal joint very short. 



Thorax dull yellow or yellowish grey, with the distinct middle stripe dark 

 brown and split all the way down by a narrow rather inconspicuous yellowish 

 grey line ; the broad middle stripe widening but little anteriorly and contract- 

 ing posteriorly to a point near the hindmargin ; side-stripes (when viewed 

 sideways) comparatively small but distinct and with the yellowish grey suture 

 conspicuously separating the larger fore part from the smaller hind part, 

 while the usual awl-shaped dark spots follow but do not extend to the hind- 

 margin ; humeral stripes continued narrowly downwards outside the front part 

 of the side-stripes. Pubescence sparse, black and bristly on all the disc (even 

 on the dark stripes), but pale and hair-like on the humeri and mixed with the 

 black bristly hairs near the humeri and all along the sides and across near 

 the hindmargin. Bristles black ; two long and strong prsesutural and one 

 weaker one more forward ; one long and strong (very rarely a second) supra- 

 alar ; two long and strong postalar ; about six (4-6) strong equidistant post- 

 sutural dorso-central and about two (1-4) prsesutural, and the hindmost of 

 these dorso-central bristles practically as strong and long as any, so that the 

 pubescence (which is rather longer on the hind than on the fore part of the 

 disc) is scarcely half as long as the bristles. Pleurae of the same dull golden 

 colour as the thorax, bearing fairly conspicuous pale pubescence on the 

 prothorax (rather dense) and on the space below, on the upper and hinder 

 portions of the mesopleume (sparsely), on the upper back part of the 

 sternoi)leura3 (sparsely), on the upper back corner of the pteropleurae, on the 

 metapleurae, on the back part of the humps at the sides of the metanotum, 

 and slightly on the hypopleurae, while the metapleural fan of long hairs is 

 distinct but only the lowest two or three hairs are at all strong, and the 

 liypopleural fan has only the uppermost bristle strong, long, and orange, 

 with the lower three or four hairs still long and yellow but only thin. 

 Scutellum of the same dull greyish yellow colour, bearing short upturned (or 

 even forwards-bent) yellow pubescence on the disc amongst which some black 

 hairs often occur about the middle, and with two or four or sonietimes_ three 

 unequal strong black (or rarely lurid reddish) upturned marginal bristles ; 

 metanotum rather shining greyish black, with the side-humps pale yellowish 

 grey and bearing fine pubescence. 



Abdomen in some lights gilded brown with pale golden hinclmarginal 

 hems, but when viewed from behind more yellowish brown with faint traces 

 of three dark interrupted stripes or rows of spots, of which the dorsal row is the 

 most evident. Pubescence on the disc short, depressed, and almost all yellow, 

 iDUt black to a small extent down the middle of the disc (especially about the 

 base of the segments and partly on the middle part of the longer hindmarginal 

 fringes) ; pubescence long, yellow, and outstanding on the sides of the pufted- 

 out crest on the basal segment, and also to a moderate extent at the sides of 

 the second segment, and slightly so at the sides of the third, while the side- 

 margins of the next four segments bear more bristly black short pubescence ; 

 scarcely any of the long hairs near the hindmargin of the basal segment can be 

 called bristles, but one or two of those near each side of the second segment 

 are practically bristles and three or four other hairs are rather strong, while 

 the third segment has one or two rather distinct bristles and about two other 

 weaker bristles near each side ; fourth segment with bristles almost similar 

 to those on the third but one or two of the strong bristly hindmarginal hairs 

 near each side are sometimes black ; similar but less strong bristles occur on
