variicornis though carefully noting the sexual differences in other Lep- 

 turae. Is the male of variicornis unknown to European collections? In 

 the male of canadensis, which is at once known by the serrate and longer 

 antennae, the elytra are usually black with the base red, or they are en- 

 tirely black. Very rarely the red color extends beyond the middle of the 

 elytra. In the female the form with entirely red elytra is most common, 

 but specimens with entirely black or bicolored elytra are also not rare. 



If the identity of the two species should be confirmed, the synony- 

 my, so far as it relates to the variety under consideration would stand as 

 follows: 



Leptura canadensis Fabr. war. variicornis Dalm. erythroptem Kirby

Lepidopterological Notes. 

 By Geo. D. Hulst. 



Mr. David Bruce of Brockport, N. Y., writes us; "Last year all the 

 Choke Cherry trees were infested with larvae that webbed together the 

 terminal leaves on most of the long branches, completely enveloping them 

 with a bag. Short stumpy larvae with reddish head, and with dull green 

 and white lines down the body, fed inside the webs, in numbers varying 

 from 30 to 100. I saved quite a lot, and they emerged HyJria undulata 

 Linn. I now remember that was the habit of the insect on Sallow in 

 England." 



This is our first knowledge of the food plant of this species in this 

 country. It is curious that while the insect is the same as that of Europe, 

 the food plant there is willow. 



Mr. Bruce also writes of Selenia kentaria Grt., "it is not generally 

 knowrvthat this insect is double brooded. All the European species also 

 are The spring brood is so much larger and richer colored than the 

 late summer brood that the latter may be thought to be another species 

 as was the case with the European. The larva of 6". kentaria is not un- 

 common on Maple and Birch in the vicinity of Brockport. 



Mr. Bruce writes further that he has had Spilosoma congrua emerge 

 from eggs laid last June and says "they vary exceedingly. I have some 

 9 s with distinct black spots on the top of the abdomen, and some ^fs 

 as nearly pure white as possible, and some well spotted. " In view of this 

 there remains hardly a doubt that S. antigone Streck., is a synonym of «S. 

 congrua Walk. As is told Ento. Amer. Vol. II, p. 15, the larva is not 

 at all Spilosoma like, but strictly an Arctia in appearance. 



Mr. Bruce yet further in his writing tells of his experience in col-
