Bruchus texanus, new species. 



Black, variegated with brown, thorax sh'ghtly tumid at middle near Ijase, eyes 

 very deeply emarginate. Head oblong oval, moderately coarsely densely punctured 

 longitudinally carinate between tlie eyes, sparsely clothed with white hairs in the 

 clypeal region, eyes very deeply emarginate, antennae black, joints five to eleven much 

 broader than the preceding. Thorax convex, slightly tumid at middle near base as 

 long as broad, sides nearly straight, base sinuate, lobed at middle, apex truncate, sur- 

 face densely clothed with brown and white pubescence, the brown predominating, an 

 antescuUar spot of white hairs, which fill out a slight impression. Elytra nearly as 

 long as wide, striate, densely clothed with brown and white hairs, the brown more 

 conspicuous in two large spots on each elytron, one at middle at sides, and on eat apex 

 and one more indistinct oblique narrow one, from the humeri to the suture. Pygidium 

 densely clothed with brownish and white hairs, the white more conspicuous in a longi- 

 tudinal line at middle. Beneath and legs black, finely pubescent with white hairs, 

 denser on the abdomen. Hind femur with a small tooth. Length, 2 mm. 



Described from one specimen taken on May 2, at Esperanza 

 Ranch, near Brownsville, Texas. Related to the two above described 

 species but narrower, with entirely black legs and thorax not gibbous 

 in front. The convex uneven thorax, the slight short median im- 

 pression near base of thorax and the femora with one tooth brings 

 this near arizoneusis, with which it ought to form a separate group 

 between Dr. Horn's Group II and III. 



Some of the Bnichus may have been described from Mexico, but 

 the descriptions are so extremely short, that it is very difficult to 

 identify the insects satisfactorily. 



Pelecotomoides nubilus Gerst. 



A small number of this interesting Ripiphorid were beaten from 

 different trees at Esperanza Ranch, most of them in July. Specimens 

 are recorded from Panama as having " ill-defined transverse or oblong 

 patches of a fuscous color" but all my specimens belong to the uni- 

 colorous form. This insect is of a grayish fuscous color, eyes large, 

 divided in front by a very narrow line, antennae with the first four 

 joints simple, the remaining flabellate in the male, strongly serrate in 

 the female. My specimens are from 5.5-9-5 nim. The genus 

 Pelecotomoides is distinguished from Toposcopits by the entire eyes, 

 which are in Toposcopus completely divided and from Pelecotoma by 

 the strongly serrate claws. The following table will help in the 

 identification of the F^vaniocerini occurring in our fauna. 



Eyes feebly emarginate. 



Claws feebly bidentate, antennre flabellate in the male or serrate in female from 

 the fourth joint ; hind tibix at apex with one small spur, third and fourth 

 tarsal joints equal ; eyes widely separated in ivox\i...Pelecoioma Jlavipes Wells.
