colour, and having the thorax and elytra margined with black. It belongs to the tlea- 

 beetles and is verj' active. It is abundant upon elm, oak, etc., in the summer and 

 autumn ; and in the early part of September (1882) I found it in great numbers feeding 

 on the foUage of the sweet hickory. 



The remaining species to be mentioned belong to the division of coleoptera known 

 as Khyncophora or snout-beetles, because the head is prolonged more or less into a 

 beak. This division contains a great number of small, or moderate-sized, species, of 

 very obnoxious habits, as the larva? live generally in seeds, under bark, or in the roots, 

 etc., of plants. The first five species belong to the family Curculionidse. 



No. 39. Mapdalis Iiarhita Say is a black species about one-fourth of an inch long. 

 The thorax is closely punctured, and the rounded sides project in front in a short, acute 

 tubercle. The head is prolonged into a slightly curved beak, not deflexed, and as long 

 as the thorax. The elytra have deep punctured stri?e, and are as long as the head and 

 thorax together. The scutellum (a small plate at the base of the elytra) is covered with 

 white hairs. The beetles are found during the summer months puncturing the bark of 

 felled and dead hickories, and the larvae live in great numbers in the bark or between 

 it and the wood. I have found the beetles most abundant from 15th to 30th June. A 

 species almost identical with this, viz., M. olyra (Herbst.), is stated in the U. S. Bulletin 

 to bore under the bark of the oak, and a smaller and smoother species with a bluish 

 tinge, M. inconspicua Horn is very abundant on our pines. 



No. 39 A. Magdalis olyra Herbst. Since the preceeding paragraph was written, 

 and in type, I have received the January number of the "Quarterly Journal of the 

 Boston Zoological Society," in which Mr. F. C. Bowditch describes this species as always 

 found by him to infest various species of Caryce. The larvae " tunnel the bark in every 

 direction, leaving only just enough tissue to prevent the bark warping away from the 

 tree." " As far as my observations extend, the species appears to prefer small trees, 

 from four to six inches in diameter." "If the tree is small and very badly infested it 

 dies very quickly ; and shortly after the beetles have escaped the bark is apt to flake off, 

 or curl up in quite large pieces." As this beetle is also found in Canada, it will add one 

 more to the present list, thus making the total number forty-nine. 



No. 40. Antho7io)niis suturalis Lec. is a pretty little weevil also found very abund- 

 antly on the bitter hickory. It is black and punctured, but shining, and the elytra 

 have each a large red spot (varying in size) extending from the tips almost to the 

 middle. The beak is longer than the thorax, and bent down, instead of projecting 

 forward as in the preceding species. In regard to the actions of this beetle upon the 

 hickory, I am unfortunately in ignorance ; but it is known to attack cranberry-vines in 

 the United States, by laying an egg in the fruit-bud and then cutting it off; the larva 

 feeding in it upon the ground. 



No. 41. Conotrachehis posticatus Boh. very much resembles in shape and colour C. 

 nenuphar (Herbst.), the well-known plum curculio, but is smaller and without tubercles 

 on the elytra. There are, however, upon the elytra slightly elevated ridges between 

 which are rows of punctures. Across the elytra, near the tips, is a yellowish band. It 

 occurs upon the foliage^ of the bitter-hickory during the summer months. An allied 

 species, C. eleyans (Say) is described by Packard as " laying its eggs in the partly rolled 

 up leaves of the pig-hickory (Carya porciiia) and during the process cutting off the 

 leaves, which hang down, wither, and turn black." 



No. 42. AcojJtus suturalis Lec. is a small black beetle, densely clothed beneath 

 and more sparsely above with short yellowish hairs. The elytra are striated and in 

 unrubbed specimens have a wide band of yellowish pubescence across the base, and a 

 narrow one near the tips, which are black, as is also the space between the bands ; a 

 white line along the suture interrupts the basal band. Found in abundance on dead 

 hickories, in the bark of which it bores in company with No. 39. 



No. 43. Balaninus nasicus Say is named the " Hickory-nut weevil" in Packard's 

 Bulletin, and according to liiley breeds entirely on hickory-nuts. Harris, however, 

 considered it probable that it bred in the nuts of the hazel, because found paired on 

 hazel-bushes in summer. In this neighbourhood it is never found on hickory so far as 

 I am aware, and frequents the hazel almost entirely. Some years it is very numerous
