THE CANADIAN ENTOMOLOGIST. 79 



Calcophorse being captured late in the autumn, but never of D. obscura. 

 Does it also hibernate ? Perhaps some one that has a better knowledge 

 of the' habits of this species than I, may be able to give us an additional 

 record of experience. The beetle, by the way, is rather a rarity in the 

 -vicinage of Montreal. J. F. Hansen, Montreal. 



OECANTHUS. 



Dear Sir : Referring to the genus Oecant/ms, I have only been able 

 to find in the works of several authors 0. niveus as damaging fruit, etc. 

 I have taken 0. niveus entirely about apple and hard wood ; O. fasciatus 

 Fitch about raspberries, etc., and certain woody weeds. They are more 

 common than niveus here, and very distinct.

ON THE FULMINATING PROPERTY IN CALATHUS GREGRAIUS SAY. 



While collecting in the woods, 9th November, 1884, I rolled over an 



old rotten log and discovered a number of reddish-brown Carabs, with 



lighter legs and antennae, which proved to be Calathus gregaritcs, Say. 



These I captured and put in a cyanide bottle. Looking at the bottle soon 



afterward, I noticed that it was filled with a white smoke, which, I soon 



saw, was emitted by the Carabs. This somewhat surprised me, as up to 



that time I had never heard of this pecuharity occurring in any other 



genus than Brachynus. Since then I have seen a notice of its having been 



observed in .J/>/r/?/,f by Mr. Ricksecker {Eutomolog. Ai?ier„ vol.1., p. 



g8). I should be glad to know if it has been noticed in Calathus by any 



other collectors.

Dear Sir : I have just become acquainted with the fact that a fine 

 specimen of Erebus odor a has been caught (in August, 1884) at the 

 mouth of Eighteen-mile Creek, a few miles south of Buffalo, N. Y., by 

 Mr. E. M. Chamot, of this city, at sugaring. The insect must evidently 

 have been bred here, as it is not rubbed at all, only somewhat torn, and 

 may not have been on the wing more than one night. It measures about 

 five inches from tip to tip.
