fine hairs are wanting. The epimerum and the episternum of the 

 mesonotum are joined by a strongly marked suture. The epimerum 

 bears one hair, the episternum none. The episternum of the metanotum 

 carries one hair near the posterior superior angle, and a very large 

 bristle just below this. 



Abdominal segments. The first tergite bears from before back- 

 wards an irregular row of hairs, a row of about 12 long bristles, a 

 row of shorter bristles, and six stout pegs or teeth between which 

 are long bristles. The second tergite carries about eight teeth between 

 which are small hairs, and behind these a row of bristles. The third 

 carries an anterior irregular row of hairs, then a row of bristles and 

 behind these a row of six teeth. The fourth has bristles like the third, 

 and four stout teeth. The fifth has similar hairs and bristles, and 

 two stout teeth near the midline. The sixth has about six long 

 hairs on each side. The seventh carries two antipygidial bristles on 

 each side. The second, third and fourth tergites have two bristles 

 below the stigma; the fifth and sixth have one. The sternites each 

 carry a row of long bristles. 



Modified segments. The eighth tergite is quite hairy. The style 

 is cylindrical and carries a long hair at the point. 



Legs. The hind coxae have several irregular rows of short, stout 

 bristles on the inner side below and toward the anterior margin. 

 Hind femur has three or four hairs on inner side. The last hind 

 tarsal joint has six spines on either margin, the last being a little 

 shorter than the preceding ones. Between the two distal spines are 

 two rather small spines. 



Relative lengths of hind tarsal joints, 22, 14, 8, 5, 9.
