216 Mr. R. MacLachlan's Monograph of 



indistinct fuscous longitudinal stripes; antennce dark 

 blackish fuscous^ the basal joints conspicuously yellow. 



Protliorax blackish, yellow behind and at the sides. 

 Meso- and lueta-th&raie black at the sides, yeUow in the 

 middle. The breast yellowish. 



Ahdomen blackish, excepting the terminal segments; 

 lateral sutures and the hinder margin of each segment 

 yellow ; in the i , the second segment is strongly pro- 

 duced in the middle above, overlapping the third ; the 

 fifth is scarcely longer than the sixth, ob-conic, trun- 

 cated and margined with testaceous posteriorly ; the sixth 

 testaceous, marked with blackish above, cone-shaped, 

 very slender at the base ; the seventh slightly smaller than 

 the sixth, more obliquely truncated in front above; the 

 eighth (terminal) short, strongly dilated, the branches of 

 the forceps shorter than in the last species; appendices 

 short, flattened, dilated and truncated at the apex, 

 usually blackish (PL XI. figs. 7a, 7h); in the ?, the 

 three terminal joints are strongly hairy, the two first 

 broad and nearly equal, the last longer and narrower, 

 with black appendices. 



Legs grayish yellow ; tihice with few blackish spines ; 

 »purs yellowish ; tarsi fuscescent; tingiies with fewer and 

 shorter teeth than in the last species. 



Wings sub-hyaline, with blackish markings, the mem- 

 brane with a decided dark tinge; the spots scarcely 

 forming fasciae, the apex narrowly margined; pterostig- 

 ma scarcely indicated ; neuration black, with some paler 

 transverse veinlets (PI. XI. fig. 7) . 



Length of body, ^ , 4^-5 lines ; ? , 5 lines ; expanse 

 of wings 10-12 lines. 



Very abundant everywhere. Varies greatly in the 

 number of the spots ; sometimes all are absent, excepting 

 the apical margination; on these variations Stephens' 

 species are founded. 



Linne's type ( ^ ) still exists in his collection, and bears 

 a label "germ." in his own handwriting. 



It may be at once distinguished by the flattened and 

 truncated appendices of the male.
