78 THE CANADIAN ENTOMOLOGIST. 



Small Torymids were present; one had been captured ))>• a 

 Thomisid spider. 



COLEOPTERA. 



Desmoris conslrictus Say. Cirey sunflower weevils were in 

 some numbers; I did not feel sure on casual inspection that they 

 were identical with our Colorado D. constrictiis, but Mr. H. C. Fall 

 kindly inforn:s me that they belong to that species. 



A single Diahrotica was seen. 



Lepidoptera. 



Eiipithecia sp. Small yellow geometrid lar\ a' were common aw 

 the flower heads, feeding on the rays, which they resembled in 

 colour. 1 bred from one of them a small Eupithecia, not \et de- 

 termined. This is the best example of a specially adapted insect 

 apparently peculiar to the Pacific Coast region, in the series. It 

 may however, have lived originally on one of the nati\e yellow- 

 rayed composita^. 



A single Pyrameis was seen on the flowers, but no other butter- 

 flies. 



Hkmiptera. 



AcJiolla lahida Stal. Common; one had captured a small 

 Halicius. 



Determined with the aid of advice from Dr. \'an Duzee. 



Lygiis pratensis L. One. 



The absence of Phymala was noteworthy. 



An aphid of the genus Macrosiphiim was abundant on^the 

 sunflowers in one place. I referred specimens to the Uni\ersity of 

 California, and Mr. Swain, who examined them, considers them 

 "nearest to M. sonchi L." They are, however, certainly not 

 M. sonchi. Chrysopa eggs were found on the aphid-infested plants. 



Arachnida. 



Spiders, which were numerous on the flowers, included the 

 following, kindly determined by Dr. N. Banks: 



Icius vitis Cockerell (Attida?). Common. 



Chiracanthinm indusujn Hentz (Clubionida^). 



Tetragnatha Jaboriosa Hentz. (Tetragnathida^.) 



Riincinia aleaioria Hentz (Thomisidie.) 



Misiimana diegoi Keyserling (Thomisida?.) 



The last is a special Californian form, represented, howe\er. 

 by a similar species in Colorado. The first is very widely'dis-
