antennal groove there is a row of about twelve short hairs in the S and about 

 six in the 2 . In the ? there is no trace of a suture from the antennal groove 

 to the vertex. The groove is posteriorly open in both sexes and extends well 

 on to the propleura in the $ . The bristles of the second segment of the 

 antenna are minute in both sexes ; the club of the antenna is half as long 

 again as it is broad in the ? . The maxillary palpus nearly reaches to the 

 apex of the forecoxa, and the rostrum extends to the trochanter, but not 

 beyond it, as is the case in silaniicwi. 



Thorax. — The pronotum bears a comb of i8 pointed spines and a row of 

 10 to 12 long bristles. The mesonotum has a posterior row of lo to 12 

 bristles, and before it about 8 to 11 small bristles on the two sides together ; 

 on the inner side, before the apex, there are 6 to 8 bristle-like spines. The 

 mesopleura have 6 or 7 bristles, and at the upper anterior corner a few small 

 hairs. The metanotum has 2 rows of bristles, the anterior one containing 9 to 

 12 and the posterior one 11 or 12. The metepisternum bears 2 bristles, 

 the sternum i, and the epimerum 6 to 8 (2 to 4, 3, i). Metanotum on each 

 side with 2 dark brown spines, one such spine being similarly placed on the 

 2 or 3 anterior abdominal tergites. 



Abdomen. — The stigmata are situated above the first bristle of the 

 posterior row, excepting the seventh segment of the 2 , where this bristle is 

 absent. The position of the spiracles is different in the sexes, the stigma 

 being close to the row of bristles in the 3 , and at a considerable distance in 

 front of the row in the 2 . The numbers of bristles on the tergites are in the 

 anterior and posterior rows of the two sides together in the specimens before 

 us : in the <? , 4 to 8, 10 ; 4 to 6, 12 ; 3 to 5, 12 ; i to 5, 12 ; i to 4, 12 ; 

 2 to 7, 12 ;-in the 2 : 6 to 7, 8 ; 4 to 9, 12 ; 2 to 4, 12 ; 2 to 4, 11 or 12 ; 

 2, 12; 2, 2, 10; 4 or 5, 8. The sternites bear one row, there being no 

 additional bristles in front of the row ; the numbers are on the two sides 

 together, in the <? : 2, 5, 6, 6, 6, 6 ;— in the 2 : 2, 6, 6, 6, 6, 8 to 11. The 

 basal sternite has in addition one or two lateral bristles on each side. There 

 are two antepygidial bristles in the S , the upper one measuring about one- 

 third of the other. In the 2 there are three, the upper being about one-fourth 

 and the lower four-fifths the length of the central bristle. 



Legs. — The hind coxa has about 7 bristles on the outer side, a row of 8 to 

 10 on the inner, and 5 to 7 at the edge, apart from the apical bristles. The 

 hind femora bear on the outside i to 3 lateral bristles anteriorly, and one 

 subapical bristle posteriorly. On the inner surface there is a row of 4 or 5 

 bristles on the mid femur and of 5 to 7 on the hind femur. The hind tibia
