28 THE CANADIAN ENTOMOLOGIST. 



it may eventually be discovered to be much more plentiful than hereto- 

 fore, since collectors have been furnished with the data for its recognition 

 by the publication of Dr. Leconte's Synopsis of the genus (Trans. Am. 

 Ent. Soc, vol. 12). Till now it has been among a set of unfortunate 

 beetles, with names in the catalogues and descriptions accessible to few. 

 It may readily be confounded with E. lifiieus, with which it is found, 

 specimens of which occur with the apical black of the elytra more or less 

 obsolete ; but it may always be distinguished by the epipleura being 

 entirely black, whereas in llnteus the anterior half is conspicuously pale. 

 The elytra are yellower than in linteus, with the external and sutural mar 

 gins narrowly black and a little cloudiness at the apex in one of my two 

 specimens. The antennae, besides having the second and third joints 

 rounded and equal, scarcely exceed in length the thorax in the male, while 

 in the female they are one third shorter. Nine specimens that I have 

 seen have the foregoing characteristics. 



Elasmoceriis tcrmiiiatus Say, was obtained in large numbers from a 

 box of dead grape vines in May and June. These grape vines also 

 yielded a multitude of Pliymatodes aiiioeni/s, some Neoclytus cryt/iro- 

 cephalus, Chariessa pilosa, Tenebi-ioides corticalis, besides other smaller 

 species. The P. a/iioeims, which had nearly pulverized the vines, had 

 mostly emerged before E. terininatiis appeared. On splitting the vine 

 several of its pupae were found in galleries excavated by the larvae them- 

 selves ; these were from four to six inches in length ; the distal end was 

 packed with coarse fibre after the manner of the Cerambycans, and the 

 other, towards which lay the head, with fine dust, leaving about an inch 

 of vacancy for the pupa. These, like the perfect insects, vary from .25 

 to .50 inch in length. They are cylindrical, the abdomen smooth without 

 projections or hooks, and having a greater diameter than the parts 

 anterior ; color entirely pale, the emargination of the eyes and tip of the 

 abdomen first become dark, then the legs and wing pads ; next the pupa 

 skin is cast, and in three or four days the head and thorax have also 

 changed to dark and the abdomen to red, and then the perfect insect 

 comes forth in quest of flowers and a mate, the time occupied in the 

 transformation having been from ten to fourteen days. 



The vines contained the larvae of several species, but which produc i 

 this beetle was not certainly ascertained, though I strongly suspect it 

 have been one that was round, six-footed, .25 to .50 inch, in length, white 

 with a very small retractile black head armed with short, strong mandi-
