66 THE CANADIAN ENTOMOLOGIST. 



asperata Lap. & Gor. has been sent me for it by good collectors. Errors 

 are mostly difficult to eradicate, and this one is not likely to be got rid of 

 soon, at least not till the genus is monographed anew. The trouble is 

 about this way. Dr. LeConte in his Monograph (Tr. Am. Phil. Soc, xi., 

 198) fully and clearly described a spreta and an asperata, which, of 

 course, went so into all collections ; but fourteen years afterwards Mr. G. 

 R. Crotch (Proc. Acad. Nat. Sci., 1873^.85) states that the names given 

 by Dr. LeConte should be reversed, but in his Catalogue misplaces the 

 species, though giving the synonyms. In Mr. Henshaw's Catalogue the 

 same order is followed, but the synonyms dropped, and now nothing 

 points to an error in Dr. LeConte's Monograph. The error was corrected 

 in few of the older collections, and is transmitted from them by tradi- 

 tion, while the latest catalogue indicates no error to one not conversant 

 with the whole literature of the subject. 



Aphodius ruftpes Lin. is mentioned at page 9. Mr. Blanchard, of 

 Mass., writes that he has a specimen collected in the mountains of North 

 Carolina. These mountains are the Alleghany, the same as at St. Vin- 

 cent's and at Deer Park. Thus, this recent discovery is already traced in 

 a direct line over this continuously rugged country more than 400 miles. 



Stenosphenus not at us Oliv. breeds in the limbs of dead hickory ; it 

 becomes a pupa the latter part of the second year and the imago is per- 

 fected before winter, but remains in the wood till the April or May follow- 

 ing. Ncoclytus capraea Say, which breeds in ash and often renders worth- 

 less logs cut before June, follows the same course. A manufacturer who 

 uses this timber showed me a log in his shop in December that must have 

 contained hundreds. When split in any direction the beetles crawled out 

 of the opened burrows and appeared quite active. 



Saperda concolor, mentioned page 8, Mr. Blanchard informs me, 

 breeds in a low willow and in Populus tremuloides — in Massachusetts, the 

 " Common Poplar," but here and everywhere west of the Alleghanies, the 

 " Quaking Asp." How many other trees are " Common Poplar ? " 



Chrysomela prcecelsis Rogers, when found, is in abundance, but its 

 habitat is limited. It feeds on the leaves of Convolvuleae (Ipomota 

 pa?idurata and Calystegia sepium) growing on the banks of rivers and 

 moist alluvial ground, but not on the same plants when away from water. 

 Its season of abundance is about the middle of June. 



Apiofi herculaneum Smith occurs plentifully about the last of May on
