THE ENTOMOLOGIST. 143 



Egga of Trombidmm Lapidum. Mr, Westwood notices 

 the eggs of this Acarus as occurring on stones : those who 

 recollect the institution of the Microscopical Society cannot 

 fail to remember also the harvest of lucubrations produced 

 by these familiar objects : great were the doubts whether 

 they were animal, vegetable or mineral : the vegetable hypo- 

 thesis, however, prevailed, and they were pronounced " mi- 

 nute Fungi." Mr. Westwood has, however, hit the right 

 nail on the head : they are the eggs of Trombidium. 



Gelechia humeralis. Mr. Barrett has beaten a fine series 

 of this micro-lepidopterou out of thatch at Haslemere : he 

 notices six varieties. 



Depressnria olerella. The same indefatigable Entomolo- 

 gist obtained this species (new to Britain) from thatch in 

 Woolraer Forest, in September and October ; he thinks the 

 larva feeds on Achilla^a Millefolium (yarrow) : the imago 

 bears a general resemblance to D. albipunctella, but is de- 

 cidedly paler, and has the pale hinder fascia much more 

 sharply angulated. 



'Young England.'' — The numbers for October, November 

 and December are principally occupied with lists of cap- 

 tures, which, however interesting to the writer, cannot be so 

 to the reader. Amongst the captures I observe Cocciuella 

 7-punctata, Pieris Brassicse, P. Rapaj, P. Napi, and many of 

 similar ubiquity. The following note by the energetic Editor 

 is of more interest. . 



"Notes on the Larvce of Cosmia diffinis and affinis. — 

 About the middle and end of last May I beat a great many 

 larvae of Cosmia affinis from the lower branches of elm trees. 

 Most of them answered Mr. Stainton's description pretty 

 well ; but two little ones with black heads, which I had mis- 

 taken at the time for diffinis, duly appeared as affinis. Mr. 

 Stainlon, in his ' Manual,' says on the larvae of diffinis, 

 'head black;' affinis, 'head green.' I at any rate obtained 

 two distinct varieties of the larvae of the latter, which answer 

 the description given in the 'Manual' of both species re- 

 spectively. I also found, about the same time, crawling on 

 some railings under a large elm, from which it had evidently 

 dropped, a pretty apple-green larva of about an inch in
