tubercle is small. The froiis bears two rows of bristles, the ante- 

 rior row containing in the c? 6 to 9 and in the 5 5 to 6 bristles, 

 the posterior row ;{ long ones, in between which there are a few 

 minute hairs. The occiput has also two rows, an anterior one of 

 5 or 6 and a posterior one of 7 on each side, there being along 

 the antennal groove a number of small hairs, in the c? an irregular 

 row of about 18, and in the $ a patch of about 6 below the 

 last bristle of the posterior row and two or three hairs further 

 forward. The propoi'tional measurements of the segments of the 

 maxillary palpus are 12, 10, 8, 16. The maxilla is long, reaching 

 to the apex of the third or base of the fourth segment of the 

 rostrum. The latter is one-third to one-fourth short of the apex 

 of the fore coxa ; the fifth segment is more than twice the length 

 of the fourth. The antennal groove is continued to the vertex in 

 both sexes. The second segment of the antenna bears in the 5 

 three bristles, which extend beyond the apex of the club. 



Thorax. — The pronotum bears a comb of 16 spines and a row of 

 15 or 16 bristles on the two sides together. There ai^e on the 

 mesonotum a postmedian row of 14 long bristles, an anterior row 

 (sometimes double laterally) of 17 to 19, and a basal row of rather 

 long thin hairs, a few additional, short, dorsal bristles being placed 

 in the cJ in front of the anterior row ; before the apex of the 

 mesonotum there are 6 bristle -like spines on the underside. The 

 sides of the mesosternite bear 9 bristles. The metatergite has a 

 posterior row of 14 or 15 bristles, and an anterior row of 12 or 13. 

 The metepisternum bears 3 or 4 bristles, and the metepimerum 

 12 to 14 (4 to 6, 5, 2 or 3). 



Al)domen. — The tergites I to VII bear each two rows of bristles, 

 the posterior row containing 1 8 ; the anterior row is reduced on the 

 posterior segments of the r? to a few bristles. The stigma stands 

 within the posterior row between the first and second bristle. 

 The basal sternite has the usual pair of ventral bristles and on 

 each lateral surface 2 or 3 more bristles. The sternites III to VII 

 bear a row of 6 to 8 bristles in the S and 10 in the 5 , there being 

 also several (about 6 to 8) small bristles in front of the row. On 

 the seventh segment the row contains 14 to 16 bristles in the 5 

 and 8 in the S • Three antepygidial bristles, in S the central one 

 about thi-ee times the length of the others, in the 2 not quite thrice 

 the length of the upper one and less than twice the length of the 

 lower one. 



Legs. — The hind coxa bears a patch of about 18 spines on the 

 inner surface. The hind femur has two subapical ventral bristles 

 on the outside and one on the inside, there being also one small 

 lateral bristle on the inside at the basal fourth. The outer dorsal 

 bristles on the mid and hind tibise are strong and all of nearly 

 even size, there being 10 or 11 such bristles inclusive of the apical 

 ones, and four long dorsal bristles on the inner side of the edge. 

 The lateral bristles are 5 or 6 in number and form one row. The 

 bristles at the hinder side of the first mid- and hind-tai-sal segments 

 are likewise strong and not quite so long as the corresponding
