144 ALLANTDS QUADRICINCTUS. 



througli the spiracles. The head is black, with paler 

 mouth, and covered with a short, scattered pile. The 

 legs have black claws. 



After the last moult it becomes of a pale ochreous 

 colour, with a pale brownish head. When young it 

 has a bluish tint, and the dorsal markings are not 

 clearly defined as regards their shape. 



The larvse have various food plants, being found on 

 the snow-berry, honeysuckle, jasmine, guelder rose, 

 ash, and on alder, according to Rudow. During the 

 day they remain quiet, rolled up in a ball, and it is not 

 till the evening that they commence to feed. Generally 

 they devour holes in the centre of the leaf, but they 

 will also eat along the edge. They form an oval cell 

 in the earth in which to pass the winter. According 

 to Brischke they line the smooth inner side of this cell 

 with silk, but this is not always done in confinement. 



The perfect insect appears in June. It does not 

 seem to be very common, Stephens records it from 

 Dover, Eipley, and Darenth ; Mr. Smith tells me it 

 is met with in Kent and Hampshire ; Mr. Dale takes 

 it at Grlanvilles' Wootton, and I have captured it at 

 Clydesdale, where the larva feeds on the guelder rose. 



It is found in Scandinavia, Germany, Holland, 

 France, Switzerland, Italy, Tyrol, Portugal, Russia, 

 Siberia.
