402 ANTHRIBIDJE. 



[LeConte. 



Antennae very slender ; prothorax without impressions or 



elevations ; pubescence nearly black 3. moestus. 



1. P. dispar Gyll., Scli. Cure, i, 140. 



This species, first described from Brazil, occurs in Missouri and Texas. 

 It differs from the following in the proportions of the antennal joints, but 

 not sufl3ciently to place the species in separate genera ; the markings 

 of the elytra are similar, but in the present species, in well preserved 

 specimens, there is a greater condensation of ochreous pubescence along the 

 first and second interspaces, which thus cease to be tessellated. Length 

 6.1-7.3 mm.; .24-29 inch. 



2. P. mixtus n. sp. 



Middle and Southern States, rare. Oblong-cylindrical, opaque, brown, 

 mottled with testaceous; head and prothorax very densely punctured, the 

 latter narrowed in front, not rounded on the sides ; elytra with an obtuse 

 elevation each side near the base, striae composed of deep approximate 

 punctures, interspaces tessellated; antennae very slender, joints of the club 

 equal in length. Length 4.7-3 mm.; .17-24 inch. 



Of the same form and color as P. dispar, but smaller, with the sides of 

 the prothorax nearly straight, and the antennae more slender, and quite 

 diiferent in the terminal joints. The second joint is more strongly clavate, 

 the 3-8 very slender, gradually diminishing in length as in P. dispar 9 • 

 but more slender, the eighth being very feebly triangular, ninth, tenth and 

 eleventh forming a loose club, the two former not emarginate, the latter 

 not narrower ; the ninth is longer than the eighth, and the tenth and 

 eleventh a little shorter. 



Three specimens are before me, in which I can perceive no sexual differ- 

 ences ; the antennae are about two-thirds the length of the body. This is 

 Tropideres caliginosus \ Dej. Cat.

Georgia and Florida. This species exactly resembles the preceding, ex- 

 cept that it is a little more robust, and the pubescence is finer and of a 

 grayish-black color, tessellated with black on the elytra ; the only white 

 spots are two small dots on the prothorax, one at the middle of the apical 

 margin, the other in front of the scutellum, which is also white. The legs 

 are annulated with dark cinereous. Length 4 mm.; .16 inch. 



The figure given by my father, like all others on the plate, is quite 

 characteristic. 



ANTHRIBUS Fabr. (nee Geoflfroy) ; emend. Lac. 



Lacordaire has restricted this generic name to those members of the 

 present tribe in which the front coxae are rather widely separated by the 

 prosternum. Additional characters are : the beak flat with parallel sides, 

 wider than long and feebly carinate in the first species ; eyes rounded, 

 convex, coarsely granulated ; antennal cavities large, extending to the 

 eyes. Antennae half as long as the body, second joint somewhat longer
