88 THE Canadian ENTO^fOLOGIST. 



Hyperaspys undulata, Say. Occasionally taken, though it can hardly 

 be classed as common. 



Scy^nnus analis. I have three specimens in my cabinet which Dr. 

 Riley identified as analis. 



In conclusion, I wish to thank Dr. Riley for his valued assistance in 

 naming the above species,

WINTER HABITS OF SOME COLORADO PROCTOTRVPID.E. 



Sir, — In the review of Mr. Ashmead's work on the Proctotrypidae in 

 the last number of this paper, a method for obtaining some of the species 

 in winter was mentioned. During a winter's collecting, mostly beneath 

 stones, boards, etc., I have found the following species (determined by 

 Mr. Ashmead) occurring quite frequently : — Pantoclis niontana, Ashm. 

 Pa7itoclis coioradensis, Ashm., Tropidopria torquata, Prov., Tropidopria 

 simnlans, Ashm., Tropidopria, sp., and Adista, sp. In some localities 

 the species first mentioned occurs quite abundantly.

CONCERNING CALOTARSA ORNATIPES, TOWNSEND. 



Sir, — In the February number of the Can. Ent , Prof Townsend de- 

 scribed and figured a peculiar fly under the above name. The figure of 

 the hind tarsus at once reminded me of a fly I had collected some years 

 ago at Ithaca, N. Y., and on comparing find that it is a specimen of 

 Calotarsa ornatipes. But I had not considered the fly as a Syrphid, as 

 its characters are opposed to almost everything of important value in the 

 Syrphidae. Not only in the absence of a spurious vein and the open first 

 posterior cell, as mentioned by Prof. Townsend, but in the small basal 

 cells, the presence of several prominent maciochaet^e on the thorax, and 

 the terminal arista to antenna. Some Syrphidje have a terminal style, 

 but an arista is different. Moreover, the origin of the anterior veins of 

 the wings is unlike that of the Syrphidre. Besides there are spurs at the 

 tips of the intermediate tibia;. 



I am not a Dipterologist ; but my specimen is labelled " Platypeza," 

 which, I think, is correct. In this position the fly is not so anomalous 

 and remarkable as when placed in the Syrphidae. Nathan Banks.
