264 H. C. FALL. 



rowed at base by the tarsal grooves. Ventral segments second to 

 fourth equal, fifth not quite as long as the two preceding united, 

 the sutures a little finer at the middle, where they are slightly arcu- 

 ate, especially toward the base. Other characters are substantially 

 as in Eutylistus. 



One species only is known. 



1. B. wetosus Lee. — Robust, oval, dark brown, rather densely clothed above 

 with grayish confused subrecurnbent hairs; surface shining. Head finely 

 sparsely punctate; front a little wider than the longest diameter of the eye. 

 Prothorax rather sparsely not coarsely punctate, the punctures faintly tuberculi- 

 forrn (their margins slightly raised ), the interspaces minutely puuctulate. Elytra 

 densely finely punctulate throughout, the interspaces nearly flat on the disk, 

 feebly convex laterally, very much wider than the sharply impressed striae, of 

 which the two outer ones are more deeply impressed posteriorly. Lower surface, 

 especially the metasternum, more sparsely pubescent; very minutely and sparsely 

 puuctulate throughout, the metasternum scarcely visibly so. Metasternum with 

 a fine sulcus or elongate fovea anteriorly. Length 3-3.5 mm. 



The larger measurement above is that given by LeConte, whose 

 type was taken at Capron, Florida. The single specimen before 

 me was captured at Enterprise, Florida, by Mr. Beyer, and is now 

 in the National Museum collection. LeConte says the antenna? are 

 10-jointed, but I can count only nine joints in the specimen at hand. 

 The fifth joint of the tarsi is as in allied genera, distinctly longer 

 than the preceding and not equal to it as described by LeConte, 

 whose description is also inaccurate in some other details. 



EUTYLISTUS new genus. 

 The present genus is established for those. species hitherto referred 

 to Dorcatoma, in which the prosternum is broadly truncate-emargi- 

 nate behind, without processes. The form is as a rule more broadly 

 oval, the punctuation simpler and the fifth ventral segment rela- 

 tively longer than in Dorcatoma, but otherwise the two genera are 

 nearly identical in structure. The antenna? are either 8-, 9-, or 10- 

 jointed, and of the same type as in Dorcatoma. The intermediate 

 joints are so small and so compactly joined that they are exceed- 

 ingly difficult to count, and it is not impossible that there may prove 

 to be some individual variation in number. The em argi nation of 

 the eye, although small, is inclined to be narrower and more acute 

 than in Dorcatoma. Those species at the end of the genus — granus, 

 fallax, etc. — by their more rotundate form and non-sulcate meta- 

 sternum form a natural transition to Goznocara. Our species are 

 moderately numerous and are as a rule easily separable.
