only slightly shorter than the fifth. Legs slender, first tarsal joint subequal 

 to the two following joints united. 

 Length 3 mm. ; width 1.3 mm. 



Habitat. "Brewster County, Texas; Rio Grande." Described 

 from a single female specimen collected by "Mitchell and Cush- 

 man," June 13-17, 1908, on "Prosopis grandulosa."

This species is closely allied to paulonotatus Pic, but the elytra 

 are darker, especially on the median parts, the markings on the 

 thorax and elytra are more conspicuous, the abdomen more 

 densely pubescent and the hairs on the elytra longer. This 

 species might be placed in the group near bimaculatus but the 

 dark and light markings of the elytra are not so distinctly sep- 

 arated, only becoming gradually a little darker on the lateral 

 median part, so it is best placed with the species having the elytra 

 nearly uniform in color. 



Ptinus barberi, new species. 



Male. Moderately elongate, parallel, uniformly reddish brown through- 

 out. Antennae four-fifths as long as the entire length of the body; second 

 joint subquadrate, about one-half the length of the third; joints 3 to 10 

 subequal in length, about two times as long as wide, each rapidly increasing 

 in width from base to apex; eleventh joint one-fifth longer than the tenth, 

 cylindrical with the apex pointed. Eyes very large and prominent; front 

 of head a little narrower than their vertical diameter. Head densely, finely 

 granulate and pilose. Prothorax rather coarsely granulate, hirsute, the hairs 

 varying in color from brown to luteous ; disk not prominent at middle before 

 the constriction. Elytra at base two times as wide as the pro thorax and 

 fully three times as long; humeri prominent; sides parallel; strial punctures 

 rather fine; interspaces fully twice as wide as the stria, each with a row of 

 suberect hairs varying but little in length, the longest about equaling the 

 distance from the suture to the second stria; setae of the strial punctures 

 shorter and more inclined; the surface is also clothed with irregular patches 

 of recumbent yellowish, squamiform hairs, giving it a motley appearance. 

 Scutellum densely clothed with very fine inconspicuous cinereous pubescence. 

 Metasternum and abdomen densely clothed with fine recumbent cinereous 

 hairs intermixed with longer erect ones of the same color, the former scarcely 

 as long as the second and third ventral segments united; fourth ventral seg- 

 ment fully two-thirds as long as the third and a little shorter than the fifth; 

 fifth without apical tubercle. Legs slender; first tarsal joint subequal to 

 the two following joints united. 



Length 2.5 mm.; width 1 mm. 



Habitat. Brownsville, Texas. Described from a single male 

 specimen collected by H. S. Barber, May 18, 1904.
