From a former subscriber. — I have no intention of taking the News 

 another year. It is too advanced for me; it shoots over my head and 

 seldom hits me. 



Query. — Has any entomologist noticed the effect of thunder storms 

 upon larva? It has been a source of considerable thought to me that this 

 may be one of the causes of the scarcity of certain common species of 

 our fauna. I base the idea on the following experience: sometime ago I 

 received a quill of Saturnia perneyi eggs, which in due time produced 

 larva, but very early, and I had quite a task to discover the food-plant. 

 I had received information with the eggs "that they fed on oak." I tried 

 all the oaks I could think of, and nearly lost all my larva; at last I tried 



* Following my identifications of Miss Wadsworth's Odonata, Prof. Harvey had re- 

 ferred the orange females to Ramburii Se:\ys. I am now satisfied that the specimens quoted 

 in Miss Wadsworth's list as " /. Ramburii female orange var." (Ent. News, I, p. 36, No. 4) 

 are really the orange females of verticalis. With Prof. Harvey's permission I have made 

 a similar change in his MS. The orange females of verticalis have a narrow humeral 

 black stripe on each side of the dorsum of the thorax, and the ist, 2d and basal part of 

 the 3d abdominal segment are orange on the dorsum. The orange females of Ramburii 

 have no humeral thoracic stripe, and the orange at the base of the abdominal dorsum i» 

 confined to the first and the base of the second segment. — Philip P. Calvert.
