PSTCHE. 



[October 1S91. 



in length, and began to spin cocoons. 

 They spun first a slight net, and cov- 

 ered it with their long hairs laid on 

 lengthwise and lying smooth and 

 flat. Through this net they pushed 

 their short hairs at right angles, or 

 nearly so, with the surface,- so that 

 these hairs stood up as if growing on 

 the cocoons, and gave them a rough 

 surface — like that of a head whose hair 

 has been cut very short, but not shaved. 

 The cocoons varied in length from |- 

 inch to ijj inches. They were of a 

 regular ovoid shape, and of a gray 

 color from the black and white hairs of 

 the larvae. Some were spun on the 



side of the tin, some on the cloth over 

 the top of the tin, and more on the 

 under side of the leaves, though with 

 no attempt to draw the' leaf over the 

 cocoon. 



The hickory trees were so defoliated 

 by these larvae this year, that I de- 

 stroyed all but twenty of my brood, as 

 soon I was sure what they were. Of 

 the twenty none died. 



Aug. 20. The pupa cast the larva- 

 skin. 



Pupa. I inch long, smooth, stout, larger 

 around the abdomen than around the thorax; 

 with ejes and antennae well marked. Its 

 color was bright tan. There was no anal hook. 



A LIST OF SOME OF THE CATALOGUES AND LOCAL LISTS OF 

 NORTH AMERICAN COLEOPTERA.— I (A.-G.). 



BY JOHN HAMILTON AND SAMUEL HENSHAW. 



In studying the distribution of certain 

 of our species of Coleoptera it has been 

 necessary to go over a considerable part 

 of the American literature ; when so do- 

 ing a memorandum of all lists and cata- 

 logues was made and is now published 

 as an aid to others engaged in similar 

 studies. 



Some of the lists contain so few 

 species as at first sight to appear un- 

 worthy of note, but frequently they 

 include some of the most interesting and 

 valuable records ; in fact the value of a 

 local catalogue is often to be estimated 

 not so much by the number of species 

 contained as by the geographical position 

 of the locality itself, and the accuracy of 

 the determinations. 



We make no comments on the cor- 

 rectness of the identifications in the 

 various lists. The student can form his 

 own estimate of them. 



All lists here quoted have been per- 

 sonally examined unless noted to the 

 contrary. 



Notice of any omission will be very 

 welcome.
