of the high interest and value of your pursuits — not less in- 

 teresting in themselves — not less conducive to the progress 

 and happiness of mankind — not less tasking the nohlest fac- 

 ulties of the mind, than those which engross the attention of 

 jurists, of soldiers, or of statesmen, when their motives are 

 the purest, and their objects are the best.

THANEROCLERUS 



SANGtriNETJS Say ; Mels. Cat. p. 83. 



Antennae 11-articulate, thicker at the apex; head dark 

 purple, finely punctured, and interspersed with short hairs, 

 truncate in front ; thorax narrower behind than the elytra, and 

 of a dark purple colour, also interspersed with short hairs ; the 

 punctures are more distinct than on the head ; elytra blood-red, 

 densely punctured, and covered with short stiff hairs ; body 

 beneath and legs reddish. Toronto, under the bark of trees ; 

 not common. Length 2 lines. 



CONOTRACHELUS 



Closely allied to C. nenuphar, Hbst. 



General color rusty red ; proboscis curved, the sides mar- 

 gined about half its length from the base, and wider at the 

 apex, which is black ; antennae elbowed, placed about the 

 middle of proboscis ; eyes black ; head short, and narrower than 

 the thorax — the latter is granulate, and through the centre of 

 which runs an abbreviated, polished, elevated line, with a 

 raised polished dot on each side : narrower than the elytra ; the 

 elytra are densely punctured, and ridged with polished protu- 

 berances in front, and a broad fascia of white silky hairs, on 

 which the punctures are rather obsolete — behind which a pro- 

 tuberance occurs on each elytron near the apex ; femorse clav- 

 ate — posterior pair toothed. Leng-th 2 J lines. 



This weevil destroys the butternut (Jif^^cwis cinerea'). About 

 the middle of August, the diseased nuts may be found beneath 

 the trees growing on the Don flats. They are generally punc- 

 tured in the side, and each contains one or two larvae. 

 I have not ascertained the time in which the ova are deposited, 

 but for the purpose of discovering the imago, I selected about 

 twenty of the diseased nuts, which were placed in a situation 

 suitable for their metamoi-phosis. In a short time the nuts 

 turned black, resembling an earthy substance, and in this state 

 I examined the larva; more closely ; only two had hecomepupa 

 and formed cocoons, the remainder (about twenty-four) were 

 attacked by a Dipterous parasite, and destroyed. The two 

 specimens obtained appeared in the imago state on the 27th of 

 August. 



TRA&OSOMA 



Hakkisii Lee. J. Acad. 2d, 2, 107. 



Antennae 10-artieulate, the basal articulation short and thick : 

 2d longer, and knobbed near its connection with the 1st ; head 

 short, inclining down, the eyes almost connect on top ; thorax 

 broader than long, and much narrower than the elytra — rather 

 rugose from the number of punctures, with a short spine on 

 each side; scutellum bell-shaped; elytra long, covered with 

 close impressions and very fine longitudinal elevations; breast 

 downy ; color dark chestnut. Toronto, very rare. Length 1 

 inch, 1 line. 



My specimen was found dead in July last on the Island op- 

 posite Toronto. It evidently had been sometime in the water, 

 which destroyed much of its natural color and freshness. 

 CALLIDrUJI 



TIOLACEUM Linn. Harr. Ins. 



Of a beautiful blue or violet color ; thorax transversely oval; 

 elytra irregularly punctured. Varies in length from 4-lOths 

 to 6-lOths of an inch, and may be found from the middle of 

 May to June. It is very fond of pine. 



I have not met a living specimen in the vicinity of Toronto. 

 The only Canadian specimen in my collection is without the 

 head ; it was given to me by Mr. Ibbetsou, who says it is rare. 

 My description is from Mr. Harris.
