^ 2 . Similar to S. simsoni, but at ouce recognised by the outer 

 bristles of the dorsal and apical edges of the tibiaeJorming a comb. 



Head. — The helmet is nearly the same as in S. simsoni (cf. Ent. 

 Mo. Mag. (2) xvi. pi. 1, fig. 3), but the comb contains on each side 

 from seventeen to twenty spines ; the bristles behind this comb also 

 as in the figure cited. The genal comb consists of six or seven blunt 

 spines and a long pointed spine placed behind the vestigial eye. The 

 occiput is twice as long as the helmet (inclusive of the comb) is wide 

 at the fifth spine. The second segment of the maxillary palpus is as 

 long as the first and about one-third longer than the third segment. 

 The apical segment of the proboscis is very short, being twice as 

 broad as it is long. The bristles of the second segment of the 

 antenna are longer than in S. simsoni, nearly all reaching to or 

 beyond the apex of the club. 



Thorax. — The pronotum bears three rows of bristles, and the 

 meso- and metanotum each four rows, the mesonotum having 

 additional bristles in front. The meso-pleura have fifteen to twenty- 

 five bristles, the episternum of the metathorax five or six, and the 

 metepimerum six to ten bristles in the first row, and five or six 

 (usually five) in the second. 



Abdomen. — The tergites bear two rows of bristles and (particularly 

 in the female) some additional bristles representing a third row ; the 

 eighth tergite has bristles above the stigma in both sexes. The basal 

 sternite bears two or three ventral bristles placed one behind the 

 other, and further back two or three lateral ones ; sternites iii. to vii. 

 of the male bear a row of four or five bristles on each side and 

 several additional bristles in front of the row, viii. has a row of four, 

 and four to eight additional bristles; in the female the bristles on the 

 sternites are more numerous, sternite vii. bearing a row of eight or 

 nine bristles and before this row another of seven to nine, on each 

 side. 



Legs. — The fore femur has on the outer surface about four lateral 

 bristles, besides the subventral ones which are placed near the apex. 

 The outer dorsal and apical bristles are nearly of equal length and
