from the incrassate margin of the antennal groove. There are two rows of 

 bristles on the frons, the anterior one containing 6 to 8 and the posterior one 

 4 longer bristles, one of these 4 being placed at the edge of the antennal 

 groove. The occiput bears three rows of bristles, the numbers of the bristles 

 being on each side 3, 5 or 6, 6. The second segment of the antenna bears a 

 row of bristles, of which the longest is one-third the length of the club in the 

 (? , while in the $ there are 4 bristles which are as long as the club or nearly 

 so. The genal angle bears two spines, the outer one being short, broad, 

 triangular, and crossing the inner one, which is long and narrow. The lobe of 

 the genal angle itself (partly covered by the spines in lateral aspect) is lanceo- 

 late. The rostrum is about one-fourth shorter than the forecoxa. The 

 maxilla reaches to the apex of the third segment of the rostrum, and the 

 maxillary palpus to the base of the fifth segment. 



Thorax. — The pronotum has a comb of 18 spines and a row of 12 or 13 

 bristles on the two sides together, there being no bristles in front of this row. 

 The mesonotum has two rows of bristles, the anterior row containing 17 or 18 

 and the posterior row 12, there being also 3 or 4 additional small bristles in 

 front of the rows, numerous small hairs at the base, and 10 bristle-like spines 

 before the apex on the inner side. The mesopleura have seven bristles. The 

 metanotum also bears two rows of bristles, the numbers being 20 and 12. 

 The metepisternum has two bristles, the sternum one, and the episternum 11 

 to 14 (in (? 5, 2, 5 or 6, 2 ; in ? 5, 4 or 5, 2). There are no apical spines on 

 the metanotum in the two specimens before us. 



Abdomen. — The first three or four tergites bear two or three apical spines 

 on the two sides together. All the tergites have two rows of bristles, there 

 being usually a few additional bristles in front of the rows, the numbers being 

 as follows: in the S 2, 16, 15; 2, 14, 18: i, 7, 17; o, 6, 17; i, 4, 18; o, 4 

 16 ; I, 6, 15 ; and in the ? 5, 15, 12 ; 2, 21, 16 ; 2, 16, 17 ; o, 15, 16 ; o, 15, 

 15 ; o, 15, 14; 3, 12, 13. The sternites bear one row of bristles and a few 

 small hairs before the row as follows ; in the c? 2, 4, 6 ; 2, 7, 6, 6 ; 6, 7; and 

 in the $ 2 ; 5, 7 ; 6, 8 ; 5, 8 ; 14, 12. The first sternite of the ? bears in 

 addition 2 or 3 small bristles on each side. There are three antepygidial 

 bristles in the ? , the upper and the lower bristles being about one-third the 

 length of the middle one. In the ^ there are two bristles above the long one, 

 the two being about the same in length as the fourth on the one side, while 

 on the other side the one nearest the long bristle is apparently (its tip being 

 broken off) nearly as long as the large bristle. 



Legs. — The hind coxa bears posteriorly before the apex 3 bristles and
