648 Mr. H. T. Stainton on the 



dark-green dorsal vessel ; the head is brown, with the sides 

 blackish ; the prothorax bears a black plate, divided by a slender 

 line ; the legs are of the colour of the body. Before it is fidl fed, 

 the parts of the mouth become rather darker, the colour of the 

 body changes to a pale orange-yellow, and on it are three purple- 

 red longitudinal lines, which consist of separate rows of spots. 

 The middle line beeins on the second thoracic segment with some 

 small spots, which on the following segments become gradually 

 broader and closer, thus appearing contiguous ; the lateral lines 

 begin faintly on the first thoracic segment, and are more distinct 

 on the second ; they are in general shorter than the middle line, 

 and the spots of which they are composed are sharper and more 

 distinct. 



" It assumes the pupa state on the ground in an elongate, loose- 

 fitting, whitish, semi-transparent cocoon, in which the larva 

 remains unchanged throughout the winter, turning in the spring 

 to a slender, brownish-yellow pupa. 



" The perfect insect is found in the localities inhabited by the 

 larvae from the middle of June to the middle of July ; apparently 

 it is not scarce, but easily overlooked. 



"Hitherto only found in Switzerland, near Ziirich, and at 

 Bremgarten (Boll.)." 



The note appended to the mention of Cosmopferyx Druryclla is 

 as follows : — 



"There is no doubt that, on account of the insufficiency of the 

 description, the name Drurella of Fabricius may, with equal 

 correctness, be referred to several species ; and, indeed, I believe 

 this is what has actually happened. At all events the C Druryc4la 

 described by Zeller (Ent. Zeitg. 1850), of which, through the 

 kindness of the Glogavian entomologist, I possess an original Sile- 

 sian specimen, is very distinct from our species. It has the wings 

 decidedly narrower than my C Schmidiella, and the abdomen is 

 of a unicolorous brown-grey; the head is more brilliantly metallic, 

 and the entire base of the anterior wings for a considerable 

 distance is purely brassy. The posterior golden fascia bordering 

 the red medial spot is placed very obliquely, and hence the form 

 of the medial spot is more triangular. The apical streak is con- 

 tinuous. According to Zeller's opinion, the larva of tliis C. 

 Druryella must mine in the leaves of the hop. 



" Unless I am much mistaken Stainton's C. Drurella (Ins. Brit.) 

 is likewise specifically distinct both from Zeller's C. Druryella 

 and from my C. Schmidiella. It comes very close to my species,
