Another locality for Depressaria rhoduchrella. — When in town a short time 

 since, I heard of anew Depres«ariu, the description of which ("resembling sub-propin- 

 quella, bat having a dark thorax," and called, if I rightly remember, "rhodochrella") 

 appeared to answer a Depressaria that had puzzled me for some years. 



I enclose one of my specimens, and shall be glad to hear about it. The species 

 occurs on our coast, along with costosa, Yeatiana, iadiella, ocellana, suh-propinquella, 

 &c., &c., in August, and it hybernates. — John T. D. Llewelyn, Penllergare,

Larentia salicaria and Camptogramma fluviata in South Wales.— I have met 

 with two examples of the former insect in this neighbourhood, — one in the present 

 year, on some niountain land near here, the other on a previous occasion, at light. 

 They do not appear to differ from the Scotch specimens.- — On the 24th of May last, 

 I found a male Camptogramma fluviata, dead, in a room where light had been 

 exhibited on the previous evening, and by which I presume it must have been 

 attracted. — Id. 



Cannibalism, of Thecla quercus. — Having received, through the kindness of my 

 friend, Mr. Mercer, half-a-dozen larvas of this species, I placed them on a growing 

 food-plant, and securely covered them over with a square glass shade. On making 

 an examination a few days afterwards, to see what progress was being made, I was 

 greatly " nonplussed " at finding my stock of larvae two minus. Feeling satisfied 

 that the missing ones could not have escaped from their cage, I resolved to keep a 

 close watch on the movements of the remaining larvae. 



On the 27th of May, one had changed to chrysalis in a corner of the shade, and 

 I observed a larva attached to the tail end of it, and evidently very busily engaged. 

 Fearing the purport of his manoeuvres, I disturbed him, and found that he had 

 not only eaten off the end of the chrysalis, but had cleaned the contents of it right 

 out ; and what still more astonished me, was that, after being disturbed, he returned 

 resolutely to the attack, and finished up the greater part of the pupa-shell. A 

 second chrysalis, which I have removed from the shade, has, I believe, been bitten, 

 for there are marks on its back where it has evidently bled. The other larva, on 

 leaving its food, went prowling about as if in search of a suitable spot to perform 

 the operation of changing ; but he might have been looking out for a nice fat pupa. 



I have somewhere heard that the larva of Th. w-albu7n has similar cannibal 

 propensities ; but still the above may possess sufficient interest to find a place in 

 the pages of the Magazine. It would be interesting to know if Thecla larvae are 

 given to such habits in their natural state, or whether they assume them only in 

 captivity. — James L. Couktice, 22, College Street West, N.W. 



Note on another cwious instounce of non- destructive parasitism. — Yesterday, 

 whilst examining my breeding cages to note the progress of some Lepidopterous 

 pupae, I discovered a fly (Tachina, consohrina) walking about in one of the cages ; 

 and 83 I thought it just possible that it might have come out from a cocoon of 

 Satumia Pavonia-minor, which had not produced an imago, I cut the case open, and 

 found the pupa-skin of the fly with the full-sized chrysalis of the moth, which had
