146 ENTOMOLOGICAL NEWS. [November, 



Allow me to call your attention to an error which appeared in Ento- 

 mological News for May, and which I think is worth correcting. The 

 Erebia which Mr. J. D. Evans collected at Sudbury, in 1889, was not epip- 

 sodea, but discoidalis, a much rarer species, and hitherto only taken many 

 degrees further North. Mr. Evans took five specimens in all, and all on 

 the same day, and one or two were also taken by Dr. E. D. Peters, Jr. 

 I have recently heard from Mr. Evans in reference to his collecting during 

 the past season, but no specimens of this interesting species were obtained 

 there this year. H. H. Lyman. 



I DESIRE to state in regard to my own observations of the cocoons of 

 Callosomia angulifera, that during the Winter of 1889-90, I collected, on 

 the Catawissa Mountain at an altitude of 1800 feet, 77 cocoons of what I 

 supposed to be C. promethea, all of which were suspended on Sassafras 

 and Wild Cherry by a silken cord covering the foot-stalk of the leaf and 

 firmly attached to the twig. Of these 12 did not hatch; from 29 there 

 emerged ichneumon parasites, and from the remaining 36 I succeeded in 

 obtaining t."] promethea and 9 angulifera, all females. I never looked for 

 or found a cocoon of angulifera on the ground. Stephen Baldy,

Dragonflies Congregating at Night. — Prof. D. S. Kellicott, of the 

 Ohio State University, Columbus, O., writes, in a letter of Sept. 16, 1890, 

 " In your observations of Dragonflies, have you found them congregating 

 at night? In July last I met, several times, with an interesting case. 

 Hetcsrina americana, as I suppose, I have not compared the descriptions 

 of Walsh's species, along the Shiawassee River, Michigan, gathers in 

 great numbers on plants overhanging the river. I often gathered from 

 twenty to thirty by one sweep of the net. Sexes mingled, males more 

 numerous." (with Prof. Kellicott's permission. — P. P. C.) 



Edward Bambrick, 32 years, of Lagrange, near Bustleton, died on 

 Wednesday, of blood poisoning, caused by the bite of a green caterpillar, 

 Nearly a fortnight ago Bambrick told Policeman Ashton, of Bustleton, 

 that he had been bitten on the neck by a green caterpillar as he lay on the 

 grass in front of his own home. The creature inflicted what seemed an 

 insignificant puncture, which bled freely. He did not heed the wound 

 until some time after, when Dr. Be3-er was called in. Medical skill failed 

 to overcome the poison, and the patient died. — Philadelphia Press. 



Any other irritant would have acted in the same way, the fault was in 

 the individual. — Ed.
