rufous tinge, antennse rather shorter than the body, tinged with rufous ; thorax longer 

 than broad, obtusely contracted each side, rather before the middle ; elytra irregularly 

 punctured, without elevated lines ; thighs dilated." Mr. Schwarz records finding it under 

 the bark of beech. (Packard 1. c. p. 79). 



21. Dri/obius sex/asciata, Say. — Mr. C. G. Siewers records (Can. Ent. vol. XEL, p. 

 139) finding five examples of this handsome beetle under the bark of beech. The grub is 

 stated by Dr. Fitch to be much like that of the common elm-borer, Saperda tridentata, 

 Oliv., but larger. The beetle is also of nearly similar form to that species, the length 

 about three quarters of an inch ; colour black, and each elytron with four oblique yellow 

 bands. 



22. Xylotrechus quadrimaculatus, Hald. — This beetle much resembles in shape and 

 colour a longicorn, Neoclytus erythrocephalus, Fab., which is often found on hickory. 

 That species, however, is smaller, and has longer legs ; the yellow markings are also dif- 

 ferent. X. quadrimaculatus is half an inch long, and of a reddish colour ; head small ; 

 thorax globose with two bright yellow spots on front margin and less distinct markings on 

 the hinder margin ; elytra with somewhat yellowish tinge and faint oblique yellow lines; 

 legs slender and pale reddish. The only specimen of this beetle which I have taken at 

 Ottawa was found resting on the branch of a beech in June. 



23. Cyrtophorus verrucosus, Oliv. — This is a common beetle, very ant like in appear- 

 ance, which occurs upon various trees, and very frequently upon flowers, such as spiraea, 

 goldenrods, etc. Mr. Chittenden has bred examples from beechwood. It varies consid- 

 erably in size, but average examples are four-tenths of an inch in length. The head is 

 small and sunken to the eyes in the thorax ; the antennse are nearly as long as the body 

 and very slender, the third joint having a strong spine at the tip. Thorax rounded and 

 humped above, very closely and finely sculptured. The elytra are angulated at the 

 shoulders, and each has an elevation near the base, along which runs diagonally a narrow 

 white line, behind which are two less oblique lines, the last being almost transverse. Some- 

 times the beetle is all black, with the exception of these white lines, and the partly red- 

 dish legs, but many specimens have the basal half of elytra (between the thorax and trans- 

 verse white line) reddish, as also the corresponding under surface and the legs. 



24. Centrodera decolorata, Harr.- — This is a much larger longicorn of which I have 

 taken one example on beech. It is about an inch long, of a chestnut red colour, except 

 the elytra and abdomen, which have a more yellowish tinge. Head moderate in size, and 

 narrowed behind the large, coarsely granulated eyes into a neck. Thorax small, narrowed 

 in front and strongly angulated, or subspinose, in the middle. Elytra at base nearly 

 twice as wide as thorax, and tapering very little toward the rounded tips ; coarsely punc- 

 tured at base, and more finely toward tips, Autennse reaching to middle of elytra, dusky 



"except basal joint. Legs moderately long and stout. 



25. Toxotus Schaumii, Lee. — A very handsome longicorn of which one of my 

 examples was taken on a small beech, in a beech grove, in July. It much resembles in size 

 and shape the preceding species, but the thorax is less strongly angulated, and the elytra 

 taper more. With the exception of a wide red band on all the thighs it is entirely black. 



26. Anthophilax attenuatus, Hald. — One example of this rare longicorn was taken 

 by me in an old beech log in May. It is in general shape much like the foregoing and 

 about three-quarters of an inch long. Head and thorax black ; antennse and legs slender 

 and reddish ; elytra brownish and mottled with whitish pubescence. 



27. Leptura subhamata, Rand. — An example of this pretty and variable species was 

 also taken in an old beech log, and I have taken it likewise on oak. It averages about 

 half an ineh in length, and is of rather slender build. The head is small and narrowed to 

 a neck ; antennae long and slender, the joints partly yellow at base. In the male the 

 thorax is black, bub in the female it may be either black with a yellowish side stripe, or 

 yellowish with a black central stripe. The elytra of the male are black, with a yellow
