212 THE CANADIAN ENTOMOLOGIST. 



not long, but rounded on the front margin ; the labial palpi are somewhat 

 longer than the maxillary, with the terminal joint much broadened, 

 pointed, outside with a dark, large shining spot. The prothorax has 

 parallel margins, and above three long, black or dusty lines, equally dis- 

 tant from each other. On the meso- and metathorax these lines are 

 separated with distinct spots, among which appear a few small black lines 

 and spots ; upon the side of the thorax two dark lines are seen on each 

 side. Legs short and not very thick, bright yellow, covered with shining 

 hairs ; on the outer side of each femur a dusty or reddish line ; each tibia 

 is surrounded in the middle with a dark ring, frequently wanting in the 

 posterior tibiae. The abdomen is almost entirely black or dusty, with 

 broad yellow rings on the sides and lower surface ; at the extremity of the 

 abdomen are found two broad triangular plates, rounded off towards the 

 end, approximate, surrounded internally with black bristles and covered 

 externally with black hairs ; under these plates are placed two auxiliary 

 palpi, one under each plate, the lower half of the following abdominal 

 segment deeply cleft in the middle, and with a lengthened fringe joins a 

 long cylindrical growth. The wings are long and narrow, the posteriors 

 somewhat narrower and shorter than the anterior pair, whitish transparent, 

 sprinkled with a great number of delicate black spots, particularly thickly 

 grouped along the radius and the inner margin of the wings, and form an 

 almost unbroken line along the outer series of gradate veinlets. The 

 venation is very open (few transversal veins) ; the veins are pale whitish 

 or whitish yellow, over the greatest part on the minute black spots ; the 

 posterior wings have dark lines and spots in a small number; pterostigma 

 whitish and black internally. (McLachlan.) 



Of course I am unable to decide if the Russian translation of the 

 English original is exact ; at least only in one place (genitals of female) 

 I find some difficulty in understanding it,
