Ahlahia quadripunctana, Riddlesclowii. 



Anchylopera cuspidana, (Trietsche). This pretty little moth is, I 

 believe, new to Britain. It is a very different thing fi-om the insect 

 figured under this name in Wood's Index. Taken at Kiddlesdovvn. 



The following have also occuiTed during the summer. 



Lozopera Smeathmanniana, May 25, Wimbledon Common. 



Spilonota tetragonaiia, Coombe-wood, June. 



Porrectaria ornatipennella. I found the pupa- case attached to an 

 oak-leaf in May, and in June the perfect insect was produced. The 

 case is the most curious specimen of insect architecture I ever saw ; 

 it very much resembles a dried labiate flower, there being a column 

 with the top curved, from under which project two leaf-like appenda- 

 ges ciu'ved downwards and inwards. How such a structure is formed 

 is to me quite a mystery. 



Notodonta tritopha. During the Essex excursion I took from an as- 

 pen a larva of a greenish grey colour, having three prominences on the 

 back, and which I thought was N. ziczac, though differing somewhat 

 from the usual appearance of that larva. It formed a slight cover- 

 ing between two leaves in the collecting box, and appeared in its per- 

 fect state on the 10th of August. It has not, I believe, been taken in 

 Britain before.

Art. XCVIII. — On the appearance of Col las Hyale. 

 By Edward Newman. 



One Sunday morning in the month of August, 1835, I was quietly 

 walking by the side of the Croydon Canal — now, alas, no more ! when 

 I saw a yellow butterfly passing rapidly along the opposite bank, and 

 though for the first time in my life, I knew that I beheld Hyale. He 

 flitted up the bank, which was steep, and was soon out of sight. The 

 next day, and day after day, whenever the sun shone, I shouldered 

 my net and hunted all the lucerne fields by the canal in pursuit of my 

 nimble friends, and many a weary chase they gave me, for they seem- 

 ed to possess the wings of the wind ; however, what with this species 

 and Electra, I seldom returned without one. I often met with a 

 companion — a Mr. Ardly, a Rotherhithe schoolmaster, of whom, as of 

 Crabbe's weaver, it might be said, —
