292 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Lepturges querci (Fitch) has not been proved as yet to live either in 

 the oak or hickory, but Mr. Harrington has captured specimens on the 

 hickory "either on the bark of felled trees, or among the foliage of 

 living ones." Another doubtful hickory species is Ryperplatys aspersus 

 (Say) which bores in the poplar, but is not uncommon at Ottawa upon 

 the bitter hickory. 



18. Ecyrus daaycerus (Say). 



This beetle has been bred from hickory twigs by Dr. LeOonte. 



The beetle is nearly of the same size and shape as the Leptostylus macula. The pro- 

 thorax has slightly rounded sides, without any spines or tubercles. The pubescence 

 is close and coarse, the body of brown or grayish brown, somewhat mottled. The 

 antennsB are as long, or a little longer, than the body. 



19. Hupogonius vestitus (Say.) 



Professor Riley has bred this longicorn beetle from the hickory. 



The beetle. — Chestnut-red, mottled with short yellowish pubescence, and clothed 

 above with longer dark hairs arising from punctures in the surface. Head and thorax 

 darker and more closely punctured than the elytra. The legs and antennae are also 

 hairy, the latter being as long as the body. Length 8-9™"". 



20. Clytanthus albofasciatua Lap. 



According to Dr. John Hamilton of Allegheny, Pa., this beetle has 

 been raised both from grape-vines and from hickory limbs. "There are 

 two color-forms, produced indiscriminately, that are so different in ap- 

 pearance that judged by color alone they would form two species. Tlie 

 one is entirely black, with the usual anterior and posterior white bands 

 on the elytra; the other is black with the antennae brown ; the part of the 

 elytra anterior to the posterior white band, the femora, the coxal part of 

 the prosternum, the mesosternum and metasternum, rufous. This is ex- 

 actly the color of the more plentiful form of Cyrtophorus verrucosus, and it 

 is not difficult to confuse them. They may be readily distinguished by 

 the compressed thorax and the spines of the antennal joints of the lat- 

 ter, as pointed out to me by Dr. Horn. The same color variation oc- 

 curs in Psenocerus supfirnotatns, a few specimens of which, taken on 

 the wild gooseberry, were entirely black, except the usual white mark- 

 ings on the elytra, and so different is the appearance that it required 

 close attention to other characters to be convinced that they were the 

 same species." (Hamilton.) 



21. Jnthaxia viridifrons Gory. 



This handsome little beetle, says Mr. Harrington, was bred from 

 hickory twigs by Dr. Le Conte, " and has very frequently been found 

 by me upon the trees in summer." (Rep. Ent. Soc. Ontario for 

 1883, p. 45.) Mr. F. H. Chittenden has also bred it from a pupa taken 

 from a dead branch of sUag-bark hickory. (Ent. Amer., v, 219.) 



The beetle. — Brown, with a bronze luster. The front of the head in the males is of 

 a vivid green. Length, .2 inch.
