Stilpnotia salicis. — Excessively abundant on a row of poplars, on Chat- 

 ham Lines. 



Porthesia auriflua. — Very abundant. 



Lithosia aureola. — Scarce. I took two specimens about the end of May or 

 beginning of June, although the time usually given is much 

 later. 



L. grheola. — Scarce. One specimen by beating. 



Cybosia mesomella. — Scarce. Two specimens by beating. 



CEnhtis quadra. — Scarce. 



Miltockrista miniata Scarce. One specimen came to light. 



Euthemonia russula. — llather rare. Occurs in the clearings of the 

 woods. 



Nemeophila plantaghm. — Excessively abundant, but local. One after- 

 noon in May I captured a great many after 5 p.m.; before that, I 

 had only seen one or two. 



Arctia villica. — Rather scarce. 



Eriogaster lanestris. — I found one colony of the larva of this insect on 

 blackthorn. They spin a very thick, tough web. 



Clisiocampa castrensis. — I succeeded in breeding about 120 specimens 

 of this local species. The larva I found on the muddy banks of 

 the Medway, feeding on a Polygona {Roberta is, I believe, the 

 species). When young they are gregarious, and live in a large web ; 

 after moulting they separate, and finally spin up amongst the roots 

 of the grass, or between two leaves of the Polygona, It is very 

 hard to find the cocoon, although the larva are so numerous and con- 

 spicuous. 



C. castrensis seems to be very lazy in constructing its cocoon, as, on 

 two or three occasions, several united their efforts to construct a 

 large one, in which the Chrysalides were placed without any inter- 

 vening web. 

 Odonestis Rotatoria. — Very plentiful as larva. 

 Cilix up inula. — Several specimens occurred. 



Platypteryx lacertinaria. — Only one specimen. 



Drepana hamula. — I obtained one specimen 7 at a gas lamp.
