REVISION OF THE TENKHIUONIDyE OP AMERICA, 



head is deflexed and the front nearly vertical. The thorax is feebly emarginate in front 

 and the eyes entirely free. The elytra axe rather deeply eight striate;, the striae punctured, 

 the interstices convex and very finely punctured. The under surface is smooth, being 

 finely punctured. The legs are dark brown or black. 



Length .30-.35 inch. 



Occurs not rarely in the extreme Southern States. Numerous specimens collected in 

 Florida were given me by Mr. Levi Taylor. 



H. co 11 color, Lee, New Species, p. 121. 



This species is similar in form to femoratus, differing by the greater width of thorax, 

 deeper elytral stria', and black legs. The third joint of the antenna; is scarcely longer 

 than the fourth, and the outer joints are broader than in either of the preceding species. 

 The mentum is here somewhat different in form from cither of the others, being broader 

 than long, rounded on the sides, the lateral lobes not distinct. The middle is slightly 

 elevated, with a groove on each side. This form appears to be an intermediate one be- 

 tween the trapezoidal mentum of femoratm and the distinctly trilobed one of ater. The 

 short third antcnnal joint exists in the three specimens before me. 



Length .34-.3G inch. 



This insect occurs, very rarely however, in Canada and the Lake Michigan region. 



SCOTOB^ENUS, Lee. 



Scotobeenus, Lee, Proc. Acad. 1859, p. 88. 



The species of this genus is somewhat similar in form to Iphthimus, being, however, 

 more depressed. The mentum is distinctly trilobed. The middle lobe prominent in front, 

 convex along the middle, with a groove on each side;, lateral lobes rather small, inflexed 

 and with the angles acute. The gular peduncle moderate. The front is hcmi-hexagonal, 

 with the suture of the epistoma rather strongly impressed. Thorax emarginate in front 

 and at base, with the hind angles acute; and moderately prominent. The epi pleura) are 

 not entire. The; femora are slightly clavate and compressed. 



S. parallelus, Lee, Proc. Acad. 1859, p. 88. 



Black, sub-opaque. Thorax broader than long, narrower behind. Elytra truncate; at 

 base, humeri prominent. Sculpture consists of rather coarse punctures, the interstices be- 

 ing more finely and densely punctured, as in Iphthimus serratus. The general form is 

 similar to the species indicated, but the sides are nearly parallel. 



Length .7 4-. 8 2 inch. 



From the region of the western base of the Sierra Nevada Mts. of California, from 

 Sacramento to Visalia. Not common.
