TRIBE XII. ANTHONOMIXI. 295 



perature, meanwhile moulting: two or three times. Hunter & 

 Hinds (1905) state that the pupal stage is passed in the enlarged 

 cavity and takes from four to 15 days. Where found in numbers, 

 a half dozen or even more weevils may he developed in a single 

 boll, which is completely destroyed by their feeding. The adults 

 feed upon the squares or young bolls and also upon the leaves, 

 and the damage which they do is as much or more than that of 

 the larva?. Both larvae and adults hibernate, the latter attacking 

 the young cotton early in the spring. Cotton is the only food 

 plant and the spread of the beetles which takes place each fall 

 will doubtless eventually cover the entire cotton growing area of 

 the United States.

Elongate-oblong. Head, beak, thorax and under surface piceous; 

 elytra usually dark reddish-brown, the suture fuscous; scape, first joint of 

 funicle, and legs except the knees, pale reddish-brown; upper surface 

 shining, finely and sparsely clothed with whitish pubescence, somewhat 

 condensed near hind angles and along median line of thorax; scutellum, 

 under surface of head and sternal side pieces densely clothed with yellowish 

 pubescence. Beak shining, finely and remotely punctate, indistinctly 

 striate; head opaque, finely and sparsely punctate, the frontal fovea small. 

 Thorax convex, slightly wider at middle than long, sides straight on basal 

 third, thence strongly rounded to near apex, disc densely and rather coarse- 

 ly punctured. Elytra oblong, one-fourth wider at base than thorax; strial 

 punctures small, feebly impressed; intervals wide, almost flat, nearly 

 smooth. Length 3 3.5 mm. 



Steuben Co., Indiana, rare; June 17. Ranges from Virginia 

 and Maryland to Michigan and Cincinnati, Ohio. Schwarz states 

 (1884, 84) that it oviposits in the flowers of the wild senna, 

 Cassia marylandica L. Varies in color, the upper surface some- 

 times wholly, the legs in great part, black. The additional tooth 

 of front femora is a very small acute cusp in front of the base of 

 the main tooth.

"Resembles gularis in form and pubescence. Beak more densely 

 punctured, less shining; median elevated line scarcely attaining the base; 

 head opaque, densely and finely punctured; front with an impressed line. 

 Thorax rufo-piceous. Elytra bright ferruginous, periscutellar space and 

 suture dark piceous; front tibiae fringed with hair along the inner margin; 

 front tibiae of male curved inward near apex, and the internal angle 

 produced in the form of a broad hook (Fig. 79, h.) ; legs and abdomen 

 along the middle ferruginous. Length 2.5 3.4 mm." (Dietz.) 



Described from Cobb's Island, Va.
