finely punctured; mouth fulvous; eyes with golden reflections. AntenniB 

 brown, filiform, nearly as long as the body, beset on the inside with rather 

 long, stiff, whitish hairs; 11-jointcd, second joint very short, third joint 

 twice the length of the fourth which is shorter than the fifth. Thorax 

 black on the disk, brownish on the sides and beneath, wider than the 

 head, narrowed posteriorly, sides rounded, distinctly and irregularly punc- 

 tured; three rather indistinct smooth elevations on the disk. Scutellum 

 large and rounded. Elytra rather wider than the thorax, finely punc- 

 tured; deeply impressed on the suture behind the scutellum; on each 

 elytron, before the middle, there is a somewhat oblique, narrow, white 

 mark, slightly angulated on the lateral margin but not reaching the suture, 

 and at the posterior fourth, a broader, transverse, white mark, not conflu- 

 ent with either the lateral margin or the suture; tip rounded, entire. Ab- 

 domen black; coxae fulvous. (Unfortunately the legs are missing.) Length 

 8 lines, breadth less than one line. 



At first appearance this insect looks like a small variety of C. varians, 

 the markings of the elytra have the same position, but the form of the 

 body is much more linear. The difference in the antennae is sufficient to 

 render it distinct and probably refer it to another genus ; in this species 

 the third joint of the antennae is twice as long as the fourth, whereas in 

 C. variam the third, fourth and fifth joints are about equal. It was col- 

 lected in the neighborhood of Philadelphia by Mr. (jreorge Newman, and 

 presented by him to the Society. 



Callidium (Phymatodes) semicircularis n. sp. 



Reddish-brown; a white band on each elytron enclosing a rather large, 

 semicircular, black spot. 



JI((b. Pennsylvania. 



Body reddish-brown, clothed with rather long whitish hairs. Antennae 

 brown, basal joint reddish-brown, sparsely clothed with long white bristly 

 hairs. Thorax flattened, rounded on the sides, with a smooth dorsal line. 

 Scutellum covered with whitish pubescence. Elytra black, ante- pj„ 4 

 rior third reddish-brown ; a little above the middle on the lateral 

 margin of each elytron commences a white band which is angulated 

 anteriorly and becomes confluent with the suture down which it 

 extends in a narrow line to the posterior fourth where it widens 

 and crosses again to the lateral margin, enclosing a rather large semicir- 

 cular black spot (see Fig. 4) ; clothed with whitish hairs which are long
