broud, us lomj us hut nurrower than the tibin, which hus both outlines ilistincttii conirex 

 and the posterior basal elevation well marked. The hand is distincUy lonycr than the 

 tibia and 1-4 broader, Id longer than broad, but only 13 longer than deep, and PA 

 longer than finger. Basal "tactile" hair of fourtli pair of tarsi; tibia of the first pair 

 as long as the tarsus, which is 5 times longer tluin deep. 



??. Céphalothorax. — Ocular spots almost ohsolete. The céphalothorax is 

 (lislinclly longer than broad in the middle, where it is broadest; outline in front 

 moderatel}' convex, tapering towards anterior margin, but behind almost straight. 

 Transverse median line seems to be present and to be curved backwards in the 

 middle, but it is very indistinct; the integument of the first thoracic tergite is 

 smooth, but that of the head and second tergite is apparently reticulated, being 

 printed all over with muscular spots; the hairs are fairly long and obtuse. 



Abdomen. — The abdomen is long and slender, twice as long as broad; the 

 tergites slightly increase in breadth towards the tenth, but much more in length. 

 The three first have an odd structure, as they are provided with a descending 

 lateral portion, perpendicular on the dorsal part; the following are regularly convex 

 from the one side to the other. The three first tergites have in addition to the 

 other irregularity the median part longitudinally hollowed with the lateral parts 

 raised; this depression becomes narrower in the following tergites and is in the 

 sixth to the eighth represented by a longitudinal groove with a longitudinal black 

 ridge in the middle. The integument is smooth or minutely reticulate. 



Antennae. — The flagellum consists of füur('?) hairs; the lamina interior 

 has three denlated lobes and a long terminal spine with six teeth. The three basal 

 teeth of the serrula exterior show a remarkable structure, perhaps an abnormal 

 one; the long basal tooth is directed obliquely forwards and has the lateral margins 

 turned over forwards with its membranaceous part, so that a kind of spoon is 

 formed ; the third tooth is distinctly pointed, and so is the second, which is much 

 shorter than this and wedged in between the two others. The galea is partly lost 

 in this specimen, but extends beyond terminal hair and is provided with two 

 branches at least. 



Maxillae. — The maxillae are smooth in the middle, slightly granular 

 laterally, and have long and slender manducatory parts, which are distinctly 

 longer than the lamina maxillaris. 



Palps (PI. IV, fig. 3 a). — The palps, which are shorter than the body, are 

 granular with minute and low granules everywhere except on fingers; the hairs 

 seem to be fairly long and provided with a few teeth distally; the fingers bear 

 tactile hairs and spots. The immovable finger bears two basal and two median 

 tactile hairs anteriorly in addition to seven sense-spots, arranged in an irregular 

 longitudinal row in the basal third; posteriorly it bears two basal and a single(?) 

 median tactile hair in addition to six sense-spots in the basal third. The movable 

 finger bears three sense-spots, placed near to each other, establishing a triangle at 

 the base anteriorly, and posteriorly three basal and two(?) median tactile hairs in
