THE CANADIAN ENTOMOLOGIST. 



ON THE OCCURRENCE OF TWO SPECIES OF COLEOPTERA 



NEW TO MONTREAL. 



BY J. F. HAUSEN, McGILL COLLEGE, MONTREAL. 



F/atynus crenistriatus, Lee. I took a specimen of this interesting 

 little beetle (fig. i) here late in October, at the foot of a stump. It is not 



unlike in appearance certain small Fterostichi, 

 but may be at once distinguished by having the 

 elytral margin behind sinuate and simple, with- 

 out the interruption and route fold usually seen 

 in Pterostichus. It seems to me to be, in fact, 

 one of those less specialized forms still exhibit- 

 ing characters in common with some species of 

 that genus. The form is convex, black and 

 shining, with the elytral furrows deep and 

 strongly punctured, feet and three basal joints 

 of the antennas bright yellow, the external 

 margins of the 

 elytra and edge 

 of the prothorax 

 beneath piceo testaceous. Whether it is com- 

 mon elsewhere I know not, but it is the first 

 specimen I have yet met with here. It seems 

 of rather wide distribution, as the specimens 

 from which Leconte originally drew up his 

 description (New Species of Coleoptera, p. 

 9, 1863,) were obtained from Illinois. 



I took with this an example of another 

 singular Platynus not usually found here, 

 and which Dr. Leconte has replaced under 

 the old name under which it was described, 

 namely, Anchus pusillus, Lee. Specimens 

 are also in my coUeetion from St. Je'rome, 

 P. Q., and Northern Vermont. 



Some time since I was handed, for iden- 

 tification, by one of the members, a little Fig. 2.
