 of the sides. Scutellum and mesonotum in front very shining. Epi- 

 notum fairly dull, finely shagreened, the dorsum as wide as the 

 declivity. Scale high, thin, trenchant at the summit, slightly concave 

 hehind. Wings hyaline, with rusty-red nervures, the anterior wing 

 14 mm. long. Colour, pilosity and sculpture as in the Qj.. 



cf, 7'5 mm. Yellow. Three elongated spots on the mesonotum 

 and the base of the abdominal segments brownish. Sculpture and 

 pilosity as in the ^. The cheeks less hirsute. Head longer than 

 wide, rounded behind the eyes, which are very convex and occupy 

 the whole of the middle third of the sides. The scape extends by 

 more than half its longth beyond the occiput. Clypeus strongly 

 carinate, mandibles dull and shagreened, finely dentate. Epinotum 

 only slightly convex from above to below, its two faces not distinctly

Contrary to the author's statement, the head of the % in all the 

 specimens before me is just as dull as in the race, and the abdominal 

 spots are, if anything, more distinct. The only notable difference 

 which I can see is, that the ^ minor has the abdominal spots 

 clearer and paler, and widened so as to form almost complete trans- 

 verse bands. The head is just as wide behind as in the race. In 

 my opinion, the separation is not justified by such triflng differences 

 and the varietal name should be suppressed. (S.A.M., G.A. colls.).
