are entirely or nearly piceous, except the legs and antennae. Haldeman's 

 description is so bad that it took Drs. Leconte and Horn more than thirty 

 years to find out that gibbulus was synonymous. Gibbuhis is fairly 

 described ; niger could not well be known had not the describer himself 

 made the synonymy. It would appear from the Jour. Acad., 1. c, that he 

 intended to cite gibbulus from Agassiz, Lake Sup., but by a slip of the 

 memory wrote niger, hence the (| niger) cited above which seems a 

 rather doubtful use of the error mark. But in writing the description he 

 evidently had a different coloured example before him than th^t from 

 which he described gibbulus. This species, though distributed from the 

 Lake Superior Region and Canada southward to Virginia is not commonly 

 taken, though it might be were its habits more generally known. Its 

 biological record, so far as I know, is as follows : Mr. Blanchard dug a 

 specimen from the bark of a living white oak quite late in October, Can. 

 Ent., VII., 97. Messrs. Reinecke and Zesch dug four specimens from 

 bark on oak trees, May 6th, 1883, Bui. Brook. Ent. Soc, VI., 36, and 

 remark their longevity. Mr. Harrington took at Ottawa, Canada, three 

 examples on hickory and on sumac flowers in July, Can. Ent., XVI., 73. 



To this record I may add that I took here a male on plum blossoms 

 about the first of April. 



Prof. Jerome Schmitt, of St. Vincent College, Westmoreland Co., Pa., 

 took six females early in the season (a set of which, through his kindness, 

 now grace my collection), a history of which I am permitted to 

 publish, which I think best to do in his own words : " They were crawl- 

 ing when observed on a smooth place on a living oak, elsewhere covered 

 with rough, thick bark. Unlike most Cerambycids it is very slow and 

 staid in its movements, and difficult to see because of its resembling the 

 bark very much by its colours and its persistent hiding in the galleries of 

 the bark made by some larvae, or abandoned by a small myrmecid — 

 Leptothorax longispinosus." Prof. Schmitt also writes of having seen 

 this species several years previously on a green oak trunk under similar 

 circumstances, and thinks it very probably breeds in the rough bark. 

 These examples and that taken by myself were of the niger colour. Mr. 

 Reinecke has sent me a female and male gibbulus which so resembles the 

 common form of Cyrtophorus verrucosus as to require a close look to 

 distinguish. 



The above records appear to warrant these deductions : — 



I St. The species breeds in the rough bark of oak.
