the antennal groove. The anterior as well as the posterior portions of the head are 

 clotted all over with the j)oints of insertion of small hairs. The occiput does not 

 bear an_v large bristles except the snbapical row. This row contains eight bristles 

 on each side, the lower three standing rather close together. The rostrnm reaches 

 to the apex of the trochanter, the last segment being longer than the two preceding 

 ones together. 



Thorax. — The pronotum is dorsally longer than the spines of the comb. It 

 bears one row of bristles and a comb of twenty-eight spines. The mesonotnm, 

 which is half as long again as the metanotum, bears two rows of bristles, the hairs 

 of the anterior row being short. In addition, there is a small number of short 

 hairs on the back. At the base of this segment there is a number of very slender 

 and rather long hairs, and before the apex there is a further row of tive to seven 

 long, slender spines. There are about ten bristles on the metatlioracical sternum, 

 and about eight on the epimerum. The metanotum bears a few bristles dorsally in 

 front of the two usual rows, and there is one apical spine. The metathoracical epi- 

 sternum, which is longer than usual, bears one small bristle, and the sternum one 

 long bristle, while on the epimerum there are five (1.3.1.) bristles. 



Abdomen.— The abdominal tergites bear two rows of bristles, with one or two 

 hairs in front of them. The first, second, and third tergites bear two or three 

 spines, and the fourth one. These spines on the second and third tergites are placed 

 in a deep sinus (PI. VII. fig. 20), the edge of the segments being denticulate above 

 and below the sinus. There are four long apical bristles on the seventh segment, 

 the third being the longest and the fourth the shortest. The basal sternite has only 

 one ventral bristle on each side, while on the sternites of segments 3 to 6 there is 

 a row of four or five long bristles, besides some additional hairs in front of them, 

 these additional hairs being most numerous on the posterior segments. On the 

 sternite of the seventh segment there is a row of six bristles, with tive or six hairs 

 in front of them. 



Legs. — The hindcoxa is as broad as it is long at the meral suture. There are 

 two bristles posteriorly at the apex. The hindfemur has no bristles on the lateral 

 surface, except one small one on the inner side above the curvature of the ventral 

 margin. The hindtibia bears one row of bristles close to the dorsal pairs. The 

 longer bristles of the second, fifth, and apical pairs are very long. The sixth pair 

 is rejjvesented by one stout bristle and a tiny hair. Tlie hairs on the ventral side 

 of the tarsi are few in number, the second, third, and fourth hindtarsal segments 

 bearing only two ventral hairs, situated at the apex. The second hindtarsal seg- 

 ment bears only three pairs of bristles on each side. The fourth segment is cnp- 

 sha]ied, being half as long again as it is broad, and bearing bristles only at the apex. 

 The fifth segment is short, being about twice as long as it is broad. It bears on 

 each side four bristles, besides a subapical hair. The first and second bristles are 

 stout and long, the second being somewhat dislocated towards the middle, while the 

 third and fourth are slender. There are, besides, two subbasal ventral bristles in 

 between the first pair. The measurements of the mid- and hindtarsi are as 

 follows : —
