The <? is easily known by its dilated tarsi ; the ? is 

 very like that of variiis, but the black calcaria of the 

 front tibise are a distinguishing character ; the spines of 

 the mesopectus are rather more developed, and the 

 crenate line round the basal area of the metathorax 

 deeper. 



Length G — 7 lines.

Very like the preceding, but the 3- differs in having 

 the anterior tarsi simple and the calcaria pale, the ? in 

 having the calcaria pale and the other characters pointed 

 out at the end of the last description, also in sometimes 

 having a yellow spot on the scutellum ; the basal joint of 

 the anterior tarsi in the c? has a black central band, 

 which will easily distinguish it from any of its other allies ; 

 the ? might be confounded with anxius on account of the 

 spines on the mesopectus, but the striate basal area of 

 the metathorax easily separates it from that species. 



Length 6 mill. 



Hah. — Generally distributed, and not rare.
