Some confusion appertaining to these genera, as Stal had 

 not given the type of his genus Poecilostola, I sought the 

 assistance of Dr. Aurivillius, who kindly examined the 

 specimens in the Stockholm Museum, and informed me: — 

 " The genus PcecUostola, Stal, is not in onr collection. Under 

 the heading of llypcepa there are, however, three species — 

 costata, Fabr., semivitrea, Stal *, and venosa, Germ. Only 

 the first two of these species agrees with SiaPs description of 

 Uypcepa-, the third, venosa, agrees, as it seems to me, well 

 with the description of Poscilostola, and was probably tlie 

 species on which Stal founded that genus." There s.-ems 

 scarcely a doubt that Dr. Aurivillius has solved the problem.
