398 ANTHRIBIDJE. 



[LeConte. 



the greater part of its length, but directed transversely towards the sides, 

 and not flexed forwards; claws feebly toothed at the middle. 



1. T. pusillus, n. sp. 



Of the same size, form and color as Hormtscus saltator, brown, varied 

 with patches of fine white pubescence; eyes larger and more prominent; 

 prothorax more finely punctured. Elytra with striae of rather large punc- 

 tures; interspaces even. Length 1.2 mm.; .05 inch. 



Tampa, Florida, one specimen, Mr. E. A. Schwarz. 



2. T. approximatus, n. sp. 



Of the same form, color and sculpture as T. pusillus, but the antebasal 

 ridge is less curved, and therefore is more parallel with, and nearer to the 

 base than in that species. The hind angles near the base are therefore less 

 prominent, and the body is somewhat stouter. Length 1.5 mm.; .06 inch. 



One specimen, San Diego, Cal. ; Mr. G. R. Crotch. 



GONOPS n. g. 



This genus is also related to the two preceding, but differs from Hormis- 

 cus by the antennal club compressed, and composed of three joints equal 

 in length; the antennal cavities are small, and the eyes are deeply emargi- 

 nate and rather finely granulated. It differs from both by the claws being 

 cleft almost to the base, with the inner portions converging as in Anthono- 

 mus. It also differs from all the other genera in our fauna by the middle 

 and hind tibiae being armed with a small mucro or spine at the inner side 

 of the tip. The form is a little stouter than in Hormiscus; the antebasal 

 ridge of the prothorax is curved in the arc of a circle; towards the sides it 

 is nearly transverse, and is not flexed forwards. 



1. G-. Jftssunguis, n. sp. 



Oblong, rather robust, brown, mottled with small spots of yellowish 

 gray pubescence. Plead and prothorax opaque, very densely and finely 

 punctured; the latter a little wider than long, narrowed from the end of 

 the ridge forwards, but scarcely rounded on the sides; rapidly and con- 

 cavely narrowed behind the ridge, the end of which forms an acute lateral 

 angle. Elytra not wider than the widest part of the protharax, convex; 

 striae composed of moderate sized punctures, interspaces very finely punc- 

 tulate. Length 2.5 mm. ; .10 inch. 



Three specimens from Big Trees, California; sent by Mr. James Behrens 

 to Dr. Horn. 



Tribe II. BASITROPIXI. 



The only characters of a general kind which can be given to distinguish 

 this from the other tribes, are that the antennas are inserted under the 

 sides of the beak, and that the prothoracic ridge is quite basal, causing the 

 surface behind it to become perpendicular; it consequently attains the 

 hind angles, and is there flexed forwards, not obliquely and at an obtuse 

 angle, but rectangularly. As a farther consequence of this arrangement, 

 the basal margin of the elytra is acute.
