524 Records of the Indian Museuui. [Vol. XXII. 



one beneath each e3'e, extending to the external angle of man- 

 dible, the other two going from internal border of antennal socket 

 to inferior angle of clypeus. Eyes rather small, black, broad and 

 rounded in their superior portion, narrower inferiorh^ ; ocellar 

 spots scarcely visible at base of rostrum. Antennae rufous, 

 approximated at base, ist joint big, swollen, yellowish beneath, 

 darkened above, 2nd ioint very short, cylindrical, 3rd long and 

 slender, 4th about half as long as 3rd, 5th and following ones 

 short, cylindrical ; the 2 fir.st joints bear a short, weak pubescence 

 above only, the following to the loth are almost glabrous ; from 

 that last one on, each article bears beneath a rather thick tuft of 

 rufous hairs ; the antennae are broken off at about the 30th article, 

 but it is probable that this special pubescence continues a little 

 farther into a general regular pubescence. Mouth parts rather long ; 

 maxillae with 1 anteapical tooth almost as long as the apical 

 ones ; palpi long and very slender, the 3rd to 5th joints being 

 respectively 4'5-5'5 and 8 mm. in length ; labial palpi with ist 

 joint short, dilated at apex, 2nd lengthened, somewhat curved, 

 3rd almost as long as both preceding ones together, a little swollen 

 and rounded at apex. 



Pronotum rather dark rufous, somewhat darkened anteriorly 

 and in the middle ; anterior border weakly convex, posterior one 

 subangulate in the middle, concave laterally; lateral lobes high, 

 their inferior margin forming a rounded angle a little before the 

 middle , anterior angle completely obliterated , posterior one rounded. 

 Mesonotum with posterior margin subangulate in the middle, 

 strongly concave laterally, lateral lobes very high ; their inferior 

 margin convex. Metanotum a little shorter than the mesonotum, 

 with posterior margin regularly convex, lateral lobes not so high, 

 their inferior margin weakly convex. 



Abdomen above rufous, each tergite being slightly darkened 

 posteriorly ; 7th tergite ending in a long, slightly curved process, 

 the margins of which are almost parallel to the base, apex slightly 

 emarginate; superior face of this process compressed with a 

 rounded shelving ridge; 8th to loth tergites very short, hidden 

 under the process of the 7th, loth truncate at apex with lateral 

 right angles, feebly projecting; the jith tergite is very small, 

 triangular, actually crushed between the inferior anal valves, the 

 strange aspect of which has been already pointed out by Griffini 

 (I.e., p. 31). They are greatly developed, ending in a process 

 rather longer than the bodj' of the valve, somewhat curved, trun- 

 cate at apex, pubescent beneath ; external and superior faces of 

 the valve very strongly rounded, swollen, inferior one flat. Sub- 

 genital plate large, swollen at base, regularly convex at apex. 



Cerci rather short, dilated at base, with a short, fine pubes- 

 cence and long, scarce bristles, 



Genitalia presenting no sclerified epiphallus, the valves being 

 divided into two .groups, forming triangular lamellae. 



Anterior and intermediate legs rather long, posterior ones 

 failing ; anterior femora armed with 2 apical spines, the internal
