THE CANADIAN ENTOMOLOGIST. 73 



Agalliastes associatzts Uhl. June to Sept. All the examples I have 

 taken differ from Mr. Uhler's description in having the pos- 

 terior femora mostly black. This, with many other species 

 of Hemiptera, were kindly determined for me by Mr. W. 

 H. Ashmead. 



Agalliastes pulicarius Fall. Not uncommon at Golden, N. Y., in July. 

 No other localities are known to me. It is a common 

 European species ; but seems not to have been heretofore 

 reported from this country. 



Agalliastes verbasci H. Schaf. June and July. Common on muUen. 

 Besides the 53 species enumerated above, I have taken 25 species in 



this vicinity which, through the want of the proper material, etc., I have 



as yet been unable to satisfactorily determine. The present list, although 



fragmentary, indicates an interesting field open to northern collectors ; 



and we notice with pleasure an increasing interest in the Hemiptera, 



which have been for so long neglected. 



SOME FURTHER NOTES ON PHYSONOTA. 



BY F. B. CAULFIELD, MONTREAL. 



On May 23rd of the past year (1886) I again found Physo?iota heli- 

 afithi, Rand., on its food plant ( Helianthics decapetalus) in the same 

 locality as in the previous year. The insects were now in the spring, or 

 what I would call their nuptial dress, and were entirely of a bright golden 

 green, with the exception of the margin, which is transparent with pearly 

 reflections. In the fall dress the elytra are black, irregularly spotted with 

 white, the thorax white with five black spots. In the spring dress the 

 thorax is concolorous with the elytra, and bears only three black spots, the 

 afite?-ior dotible spot being ejitirely absent. 



During the past summer I examined many specimens belonging to 

 different colonies, and all were alike in this respect. They appeared to 

 be much more lively than in the fall, creeping about the plants and pair- 

 ing. A specimen taken in the hand, after a few feints, spread its wings 

 and flew quickly to some shrubs a few yards distant. I brought home a 

 pair taken i?i coitu, in the hope of obtaining eggs, but did not succeed, 

 although they fed and paired freely in captivity.
