22 PROCEEDINGS OF THE 



experience, never eating holes in the leaf like the other species. 

 Apparently there is only one brood in a year, and it is met with 

 during August and September. The cocoon is double, thin, and 

 yellow, and in confinement is spun between the leaves, or outside 

 in the earth, or between loose scales of bark. 



I am not sure but that the larvae go down to the earth during 

 the heat of the day ; at any rate, I have only found them during 

 the evening, never during the day, and once or twice at dusk I 

 have seen them marching up the trunks. 



The pupa is orange. 



C. viminalis is distributed all over Britain, the imago appearing 

 in June. I have met with it as far north as Kingussie. Its 

 distribution extends over all Europe. 



As parasites, Brischke (Ges. Konig., xi.) records Mesolius rufus, 

 Gr., Polyhlastus sanguinctornis, Eatz., and Acrotomus lucidulus, Gr. 



h. Apice of labrum rounded. 3d antennal joint in female curved ; beneath 

 slightly produced. Epistoma not keeled. Colour of abdomen black. 



Feet yellowish-red — rnjipes. 



Femora totally black — eradiatus. 



Femora nearly all white; wings not clearer at the apex than at the 

 base — Drewseni.

Antennae about the length of the body, pilose, deep black, the 

 joints distinctly separated; the two basal joints large, the 3d and 

 4th equal ; the 3d curved underneath ; the remaining joints 

 decreasing gradually in length, and very noticeably in thickness 

 towards the apex. Head very broad, projecting in front between 

 the antennae, shining, seen in certain lights to be covered witli a 

 fuscous down ; labrum and mandibles pale ; palpi pale-fuscous. 

 Thorax black ; sutures distinct, shining, smooth, covered with a 

 fuscous pubescence ; cenchri large, pale-white. Abdomen short, 

 thick, black ; anus piceous ; cerci short. Feet reddish-yellow ; 

 coxae, trochanters, and anterior femora at base black ; apex of 

 tarsi fuscous. Wings smoky, the apical third almost hyaline ;
