THE ENTOMOLOGIST. 185 



any influences, not even louch-paper; they will creep up 

 sometimes, only oftener walk about on the ground. Barrett's 

 description of its distinctions is an admirable one, tlie rich 

 yellow irroration and the stigmal differences being well set 

 out. I may add that I have taken a few out of a clump of 

 Michaelmas daisy. I am inclined to think the larva feeds on 

 this as well as on the tansy. They seem excessively partial 

 and local. — J. B. Hodgkinson ; 15, Spring Bank, Preston,

CatepJiia alchymista near Colchester (Entom. viii. 164). — 

 In the ' Entomologist' for July I see there is a notice of the 

 capture of Catephia alchymista in Sussex, on June 4th. I 

 have great pleasure in informing you that this fine species 

 has also occurred near Colchester this year, a single speci- 

 men having been found at rest on an oak-trunk on June 9th. 

 It was taken by Mr. Tillaney of this town, and is now in my 

 possession. Since the capture of the first British specimen 

 by Dr. Wallace in 1858, in the Isle of Wight, I believe no 

 other cafDture has been recorded till this year ; so that, unless 

 others have been taken recently, there are as yet only three 

 British examples. — W. H. Harwood ; 8, West Stockwell 

 Street, Colchester, July 22, 1875. 



Abundance of Callidium violaceum. — In a summer-house, 

 lately built of pine-slabs, in a garden at Croydon, there have 

 appeared by hundreds specimens of that beautiful beetle 

 Callidium violaceum. They were running over the surface of 

 the pine in all directions, beginning to make their appearance 

 about the second week in June, and continuing about a fort- 

 night. They have now entirely disappeared. — E. Newman. 



Answers to Correspondents. 



S. Bradbury. — Thecla Quercus, or purple hairstreak. — 

 Edward Newman. 



C. E. Johns. — Name of a Moth. — I think the moth 

 described must be Metrocampa margaritata. — E. Newman. 



J. S. — Chelifer cancroides. — Can you tell me the name of 

 the small insect, which I found this morning hanging on to 

 the leg of a fly, and looking like a parachute attached to a 

 balloon ? And what is the object of the aerial journey ?
