triangular, 10 more rounded. Eyes large, prominent. Labrum dis- 

 tinct, anteriorly ciliate with silky brown hair. 



Thorax very convex, sparsely clothed laterally with short brown 

 hair; middle of anterior portion without the distinct bulge shown in 

 Horn's figure of adult female; posterior half granulate with a median 

 longitudinal sulcus smooth: anterior half with recurved dentate tuber- 

 cles (teeth less pronounced in the females), the extreme anterior edge 

 granulate only. 



Elytra shining, glabrous; costae 4, the 2 outer indistinct; intervals 

 of inner 2 costae foveolate, smoother towards sides; the 2 inner 

 costae terminate in a tubercle (female), and in a robust tooth (male). 

 Elytra bent downward behind the upper tubercle at an angle of 

 45-60 degrees. The declivity smooth in the male, granulate in the 

 female. 



Abdomen 5-segmented, all segments equal and fully visible; entire 

 ventral surface covered with fine silky brown pile. 



Legs more or less covered with hair, front coxae prominent, coni- 

 cal, trochanters prominent, femora stout, tibiae flat and acutely dentate 

 externally, tarsi 5 -jointed, claws simple and arcuate, 5th tarsal joint 

 with a bristle-bearing pad. 



Length 38-51 mm.; width 14-18 mm. 



The adult is lumbering in its movements and has poor eye- 

 sight as one of the beetles escaped and Avhile in flight collided 

 with anything that came in its path, making its recapture easy. 

 Although the wings are well developed, the heavy body im- 

 pedes swift and unerring flight.

Mr. J. G. Bonniwell has recently sent me a specimen of Sclenis tnon- 

 otropa Grote. It is labeled, "Bradentown, Florida, ex larva, August 

 I7th." Mr. Bonniwell says: "My wife and I have raised quite a few 

 of these from the larvae. It feeds on a variety of 'sensitive plant' and 

 penetrates the stem to make its pupa." The species was described by 

 Grote in the Canadian Entomologist, 1876, vii, 209. from Texas. We 

 have specimens of the same moth from Cuba, in the Poey Collection, 

 under the name, Sclenis sueroides Gueiiee. S'ucroidcs was described 

 in 1852. HENRY SKINNER.
