gnaws its way out, is nearly large enough to admit the little 

 finger. It appears abundantly in some parts of New- York state 

 in July, sometimes doing extensive damage to the pine trees. "* 



Mr. Billings notices " in the collection of McGill College three 

 specimens from Toronto of the size of the smaller individuals of 

 H. confusor, which have a light reddish tinge different from the 

 usual colour of that species." If the specimens alluded to are in 

 the " Couper Collection" of that institution, the cases containing 

 the insects are covered with glass ; and the specimens having been 

 exposed for several years to the light, it is no wonder that they 

 have a tinge different from the usual color. 



" H. C." says : — " The description agrees very closely with the 

 reddish brown specimens mentioned by Mr. Billings as having 

 been obtained from Toronto, where from my own observations 

 they seem to be much more common than those of a cinereous 

 tint." 



Which description does " H. C." allude to — that of M. titilla- 

 tor or M. confusor? If my memory serves me, — for I have 

 neither my description nor a specimen of the insect, the lon<n- 

 corn pointed out by Mr. Ibbetson and myself as titillator, was a 

 large brown or cinereous beetle, with its elytra mottled by tufts of 

 erect short hairs of a blackish grey colour. I cannot say that the 

 collection which I sold to McGill College contained a speci- 

 men of M. titillator, but I am positive that Mr. Ibbetson, an ex- 

 cellent coleopterist, identified the form prior to his removal from 

 Toronto to Montreal.

To the Editor of the Canadian Naturalist. 



In the December number of the Canadian Naturalist, Mr. 

 Billings has described some of the pine-boring beetles of Canada, 

 of the genus MonoTiammus, and mentions that the M. titillator 

 is cited by Mr. Couper and Mr. Ibbetson as occurring at Toronto, 

 but is of opinion that the insect described is the M. confusor. 



I can confirm this idea of Mr. Billings, as the insects in my 

 own collection and in that of Mr. Ibbetson were named on refer-

 has 13 antennal joints.
