DOUBLE BROODS OF ARGYNNIS CALIPPE. 
BY H. H. BEHR. 
On the 19th of September I saw a specimen of Cadippe in the 
streets of Livermore, and settling repeatedly on moist ground. 
The following day I noticed two more specimens at the entrance of 
Arroyo del Valle, near Mr. Wetmore’s place, settling on Aplopap- 
pus and Solidago flowers. 
All these specimens were fresh and evidently not on the wing 
for more than a day or two. I probably would have observed a — 
more considerable number of them if circumstances had favored 
closer investigation. 
Now these insects were not mere stragglers, they evidently were 
members of a second brood. I do not know of any double- brooded 
species of the Aglaia type. The literature at my command gives 
no opportunities to ascertain if a second generation of Aglaia or 
Cyrene has been perhaps observed in the Mediterranean region; 
in Northern Europeit hasnot. I should like to know if the Atlantic 
species of this type Cybele, Aphrodite, etc., are double-brooded, or 
if in the State of California a second generation of any other species - 
has been observed. 
As far as known these species hybernate in the larva state in a 
lingering condition, during which, at least in artificial breeding, 
many perish. The survivors attain in spring, in very short time, 
their full size, a circumstance in surprising contrast with the slow 
development during the winter months. They transform early in 
spring, and the pupa develops the imago generally in the month of 
June, but, of course, in different localities at according periods. 
All species observed in their larva state fed on species of violet, but 
_ itis more than probable that other plants may serve for food as well. _ 
In the locality where the second brood of A. Calippe was observed 
_ by me, the wild species of Viola disappear from ie de a INE and 
are e reduced to eubierabeat a. :
