I have much pleasure in naming this beautiful insect after its captor,

CORRESPONDENCE. 



ARZAMA OBLIQUATA. 



Dear Sir : Upon my return from London on the 29th March, there 

 was awaiting me, through the kindness of Mr. Brehme, a parcel contain- 

 ing a piece of Typha stalk nine inches long, full of longitudinal burrows, 

 . indicative of larval work. In one of these I found a small sized chrysalid 

 and a larval skin. I put the pupa in my hatching box, and the stalk out 

 of the way for the time. On the morning of the 8th of April, sitting in 

 my room looking vacantly at the window, my attention was aroused by 

 observing the outline of a moth at rest on the upright centre sash. Upon 

 close inspection it proved to be a large sized Arzama obiiquata, in per- 

 fect condition. Had Mr. Brehme's chrysalid hatched and the moth 

 escaped from the box ? But it seemed quite too large to have come from 

 it. I then looked in the box, and there, resting at the top, was a small 

 sized moth, and the empty pupa case lying on the bottom. 1 then got 

 the stalk and began a careful investigation, and in the very centre I found 

 a large cavity with a quantity of fine cuttings at the bottom, the empty 

 j)upa case of my large moth, and the cast off larval skin. A natural pair 

 at the same time.
