PROCEEDINGS OE SOCIETIES. 
H. humuli .—I only met with one specimen (a female) of this very com¬ 
mon species. 
II, vellida. —Occurs in some plenty. 
H. sylvinus. —I took one or two specimens of this, the prettiest of the 
Hepialidse, as they were flying rapidly along the hedge. 
Ptilodontis palpina. —Three or four specimens occurred. 
Dilola coeruleocephala. —Yery abundant as larva. 
Orgyia pudibunda. —Common as larva, and the perfect insect comes to 
. 
Liparis salicis. —Excessively abundant on a row of poplars, on Chatham 
Lines. 
P. auriflua. —Yery 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. egrisola. —Scarce. One specimen by heating. 
L. mesomelia. —Scarce. Two specimens by heating. 
L. quadra. —Scarce. 
L. minuta _Scarce. One specimen came to light. 
Euthemonia russula .—Eather rare. Occurs in the clearings of the 
woods. 
E. plantaganis .—Excessively abundant, hut local. One afternoon in 
May 1 captured a great many after 5 p.m. ; before that, I had only 
seen one or two. 
Arctia villica .—Eather 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 he 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 potatoria .—Yery plentiful as larva. 
Cilix spinula .—Several specimens occurred. 
Platypteryx lacertula .—Only one specimen. 
P. hamula .—I obtained one specimen at a gas lamp.
