No. 26. Goes occulatus Lec. is a much smaller species, of the habits of which I have 

 not been able to find any mention. The beetle is rare, and I have only taken two speci- 

 mens. These were a pair captured on hickory in the end of June, and which were cop- 

 ulating when taken. They are hardly half an inch long, and are black, densely covered 

 beneath with short white hairs. The pubescence above is more sparse and scattered, 

 and the coarse puncturing of the elytra gives them a mottled appearance. There is a 

 black spot on each elytron just behind the middle, and the presence of these spots gives 

 to the beetle its distinctive name of occulatus or " eyed." 



No. 27. Goes jmlverulentus (Hald.) is a fourth species of the same genus and re- 

 sembles very closely Nos. twenty-four and twenty-five. It is recorded by Dr. Horn as 

 very destructive in the United States to living beech-trees, of which it attacks the larger 

 branches, and bores in them large burrows several inches long. This is the only notice 

 I find of its habits, but it is probable that it bores also in hickory, as I have taken sev- 

 eral specimens on bitter hickory in July and August. The chief points of distinction be- 

 tween this species and tigrinus appear to be in the vesture of the elytra and the length of 

 the antennae. Thek size and general colour are about the same, but the elytra of pulver- 

 iilentus are uniformly clad with short hairs, and have no appearance of dark bands. The 

 antennae (at least in some specimens) are slightly longer than the body. 



No. 28. Acanthoderes quadrigihha (Say) is reported by Schwarz as boring in the dead 

 twigs of oak, beech and hackberry, and it has been bred by Dr. LeConte from small 

 branches and twigs of hickory. It difters considerably in shape from the beetles of the 

 preceding genus, being broader and flatter. It is about one-half of an inch long, and 

 one -fifth of an inch across the base of the wing-covers. The thorax, in addition to two 

 lateral spines, has two more above, whence the name quadrigihha or " Four-horned." 

 The legs are nearly of a uniform length, and the thighs are much enlarged. The general 

 colour is a mottled grey, due to pubescence, and there is a moderately broad transverse 

 band of white in front of the middle." 



No. 29. Leptostylus macula (Say) is a very pretty little species about one-third of 

 an inch in length. The antennae are longer than the body ; brown, with the joints 

 black. The thorax is cylindrical, without spines, and with the sides white, bordered 

 above by a black line. The general colour is brown, spotted with black, and there is a 

 large white spot on each wing-cover beyond the middle. In some specimens these 

 spots together form a broad white band across the back. The elytra are not twice as 

 long as wide, and are rounded and deflected at the tips. The legs are as in the 

 preceding species. Fitch in his reports states that the larvae of these beetles may at times 

 be found very abundantly under the bark of old butternut - trees. I have taken 

 specimens upon butternut, but not so frequently as upon the bitter hickory. A slightly 

 larger and broader species L. aculifer (Say) is found upon the apple-tree occasionally. 



No. 30. Liopus alpha (Say) is one of a groupe of small long-horned beetles which bear 

 a close resemblance to one another in shape and size, as well as in their habits of boring 

 the small branches and twigs of various trees. Their larvae are rather slender, and are covered 

 with fine hairs ; they feed under bark, and are said to be fully grown in the autumn of tbe 

 first year. The only record I can find of the habits of L. alpha is one 

 by Riley, of their boring in dead apple-twigs and issuing in May. 

 The date of appearance varies of course with range of habitat. 

 My specimens have been chiefly taken in July. The beetle is 

 about one-fifth of an inch in length ; of an ashy-grey colour, 

 with the exception of an angulated black band across the tips, 

 and a black line along the anterior margin of the elytra. The 

 ^intennae are very slender, and half as long again as the body. 

 Fig. 17, which represents the apple liopus, Liopus facetus Say, 

 will give the reader a general idea of the appearance of the insects 

 belonging to this genus. ^ -pi-y. 17. 



No. 31. Liopus cinereus (Lec.) is almost identical in appearance 

 with the preceding, and is distinguished mainly by the coarser puncturing of the surface 

 of the elytra. It was bred by Dr. LeConte from twigs of hickory. 



No. 32. Lepturges querci (Fitch) is of the same shape and size, but is more variegated
