FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



reaching ont to the labial palpi and as far as the end of third joint of the maxillary 

 palpi ; there are a few hairs on the end of it. 



On the upper side of the segments behind the prothoracic is a faint, transverse im- 

 pressed line, with two or three short creases radiating from each end. On the eighth 

 ninth, and tenth rings these creases become much longer and are parallel to the 

 median line of the body, while the transverse crease disappears. 



There are nine pairs of stigmata, one pair on the mesothorax, the remainder on the 

 first eight abdominal segments. There are three pairs of rudimentary thoracic feet, 

 represented by very minute two-jointed tubercles, the basal joint consisting of a 

 simple chitinous ring. The under side of the body is more hairy than above. On 

 the underside of the prothoracic segment is a pair of round, smooth, very slightly 

 chitinous spots, which are succeeded on each of the other rings by a pair of short, 

 impressed oblique lines. 



It is nearly half an inch (.45) in length. 



It may be readily recognized by the four chitinous patches on the prothorax and 

 by the very minute clypeus and labrum. The upper side of the prothorax is inclined 

 downward towards the head, but not so much as in Clytus. 



The pupa.— It is white, with the wing-covers reaching to the end of the second 

 abdominal segment. The antennie are not much curved, reaching to the end of the 

 third abdominal segment, and resting above the legs. The prothorax is swollen just 

 behind the middle and is just as long as broad. The maxillary palpi are long, reach- 

 ing nearly to theend of the coxae. The labial palpi reach a little beyond the middle of 

 the maxillary palpi. The two anterior pairs of legs are folded at right angles to the 

 body, the third pair obliquely. Tbe first pair of tarsi reach to the base of the second 

 tarsi ; the second pair of tarsi reach to the coxie of the third pair of legs. It is a 

 third of an inch (.33) in length. 



The beetle.— Ph. amoenm has a reddish body, with Prussian-blue wing-covers. The 

 prothorax is just as long as broad, with the sides moderately convex, and broadest 

 just behind the middle. The antennae and tibiae are blackish brown, the tarsi being 

 dull red, the hind pair being darker than the others, and the femora are reddish. The 

 prothorax is distinctly punctured, while the elytra are very coarsely punctured. The 

 scutellum is pale reddish, It is a quarter of an inch in length. A single specimen 

 received from Illinois. 



15. The white-banded phymatodes. 



Phymatodes varius (Fabricius), 



Order Coleoptera; Family CERAMBYCiDiE. 



Several specimens of this beetle were met with a few years since, the 

 last of May, on the trunk of a black oak, in which, it is probable, their 

 younger state had been passed. It is closely re- 

 lated to the black varieties of P. varius Fab., but 

 is a third smaller, with the white bands much 

 more slender, and the surface of the wing-covers 

 is perceptibly more rough than in my specimens 

 of that insect, notwithstanding their smaller 

 size. Its thorax is densely punctured, with a 

 short smooth stripe between the center and the 

 base. One of the specimens varies iu having 

 the posterior white band wholly wanting.

I have found near Providence several of these 

 pretty little beetles, of both sexes, running in
