size, in the somewhat different arrangement of the markings, and in the form of the 

 genital segment below of the female. I have seen two females only, and possibly the 

 male may show greater differences than the female does. 



$ . Widely ovate, widening to the middle, then parallel-sided. Dull yellowish 

 testaceous, with very sparse fuscous pubescence. Markings black or brownish-black, as 

 follows : — Head with an oblong mark between the eyes, slightly split behind and united 

 to a line on the inner side of each orbit by a short slender line. Pronotum : front margin 

 broadly between the eyes, joined on each side to a short thick line running backwards 

 and then curved outwards ; a small spot behind each eye, and a percurrent central line 

 tapering to a sharp point on the hind margin. Mesonotum : front margin between the 

 shoulders ; a central percurrent line not reaching the abdomen ; a thick short line on 

 each side of the centre ; a slender short line curved inwards from each shoulder ; a 

 slender line on the side not reaching the base or apex ; on the disk an obliquely trans- 

 verse line with curved ends embracing the short thick line, and sometimes joining the 

 slender curved line thiit rises from the front margin ; posterior to this a blotch on eacli 

 side, united by a straight transverse line to the central longitudinal line, gives rise to a 

 line which, running outwards and forwards, is looped backwards and divides, one branch 

 going to the counexivum, the other to near the base of the middle legs ; a short thick 

 line in front of the hind legs but reaching the rim of the acetabulum. The anterior ends 

 of the connexivum joined by a broad transverse line in which the central longitudinal 

 line ends ; posterior to this another transverse line. 



Clypeus and apex of antenniferous tubercles fuscous. Eyes black. Antennae fuscous 

 brown, first joint ochreous at base above and for a little way beyond base below ; joint- 

 let reddish-brown. Rostrum pale ochreous with a brown spot at the base, apex of the 

 third and all of the fourth joint shining black. Front legs : outer side of acetabula with a 

 pale brown small spot ; coxte pale ochreous with a blackish spot near the apex ; tro- 

 chanters pale ochreous, with a few blackish spots at the apex ; femora ochreous with the 

 base exteriorly, a short streak in the middle above and to the inside, and a longer streak 

 in the middle below and to the outside, as well as the apex, brown or brownish-black ; 

 tibia and tarsus fuscous black. Middle legs : acetabula with the rim above, a streak from 

 it above, and a spot on the outer side brownish-black ; coxse dirty ochreous, base and 

 apex brownish-black ; femora dirty testaceous with fuscous pubescence, outer side with a 

 brownish-black streak from base to apex ; tibia and tarsus fuscous black. Hind legs : 

 somewhat similar in colour to the middle legs. Abdomen above black, hind margins of 

 the segments yellowish testaceous or pale fulvous in the middle, the pale markings on the 

 posterior segments becoming triangular in shape. Second genital segment fulvous with apex 

 Ijlack. Connexivum fulvous yellow, front and hind margins more or less broadly blackish- 

 brown. Under side of the body dirty ochreous, with a slender fuscous streak on each
