BLENNOCAMPA BIPUNCTATA. 243 



rose and the other on alder. On the Continent it is 

 found in Sweden, Germ; my and France. 



I do not know that anything for certain can be said 

 to be known regarding its early stages. Dours (Cat. 

 Syn., p. 18) says that the larva feeds on roses, but 

 whether this is an actual observation of his own, or 

 merely copied from Boisduval, I do not know. The 

 last-mentioned author describes the larva as feeding on 

 rose twigs, but the description which he gives of the 

 larva and its habits agrees so closely with that of 

 Poecilosoma candidatum that I think he must have 

 mistaken the latter for bipunctata, which it is not 

 unlike. 



The synonymy of this species is rather confusing. 

 Andre quotes lineolata, Zad., ? , and pubescens, Zad., 

 J , as synonymous ; but the species I have described 

 above is neither the one nor the other, nor possibly is 

 it even his bipunctata, for he describes the 3 as having 

 an open discoidal cellule. Lineolata, Zad., on the 

 other hand, is the same species I have described under 

 that name ; while, according to Zaddach, pubescens $ 

 has an open discoidal cellule, and has, judging from 

 his figure, the third cubital cellule longer, being as 

 long, if not longer, than the second. Giraud (Ann. 

 Soc. Ent. FT. (5), i, 380386) says that what Zad- 

 dach has described as the <? of pubescens is the <? of 

 lineolata, which is, according to him, only a var. of 

 bipunctata ; but the latter observation is certainly incor- 

 rect, although he may be correct in his former state-, 

 ment. Andre again quotes albipennis, Zad., as a syno- 

 nym of lineolata, KL, Htg., non Zad., because, I pre- 

 sume, Hartig makes lineolata a Blennocampa. If this 

 be really the case then lineolata, Zad., Cam., will 

 require a new name ; but in the absence of definite 

 information to the contrary (and it must be remem- 

 bered that practically lineolata <$ is a Blennocampa, 

 and that my lineolata agrees perfectly with King's 

 description, where no mention is made of the neuration 

 of posterior wings), I prefer to retain the name. My
