242 BLENNOCAMPA BIPUNCTATA. 



The larva appears in June feeding on oak leaves. 

 It is green, with a yellowish dorsal line, through which 

 the food canal shines as a dirty dark green line. On 

 each side of the dorsal line stand five lines of thorns, 

 and next to them, on the sides, are two rows of smaller 

 thorns; while over each proleg are placed two black tuber- 

 cles, placed one behind the other, the front one bearing 

 a split and the posterior a single thorn. Those on the 

 posterior segments are green ; under these are two 

 green single thorns. Upon the last segment are six 

 single thorns arranged in a half circle. The feet have 

 brownish claws, and have, at their base, an irregular 

 brown splash. Head brown, slightly pilose, darker 

 above and at the sides as well as at the mouth ; the eye 

 spots are large and black. After the last moult the 

 larva appears deep green with a deep orange-yellow 

 back and dark green dorsal stripes ; the head is deep 

 green. 



This is not a common species. I have seen it from 

 Worcester, from Perth and Thornhill. 



Continental distribution : Germany, France.

Apparently it is not common in this country. I 

 have only seen two specimens ; one from Kinguessie 

 and the other from Rannoch ; the former taken on the
