21. I*, texauus Pic. 



The type of this species, which M. Pic has kindly sent me for ex- 

 amination is a female intermediate in appearance between exhnvus 

 and iuterruptus or concurrens. In its somewhat robust form and 

 dark color it resembles eximius, or more strictly the eastern exam- 

 ples which I have referred to that species, but it is smaller, with 

 rather shorter erect hairs, and with the short oblique discal dash 

 extending onto the fourth interspace, I have associated under this 

 name numerous specimens from various localities in Texas, which 

 exhibit quite a little variation in minor details; in all these the 

 males lack the apical ventral tubercle. Specimens from Brownsville, 

 Texas, have the eyes excessively large, the front scarcely equal in 

 width to their vertical diameter, and the strial punctures somewhat 

 coarser; these possibly indicate a distinct closely allied species. 

 Good series of both sexes from many localities must be collected 

 before we can determine specific limits in this difficult group with 

 any degree of certainty. 



Texas, many localities; Georgia, St. Catherine's Island. 



22. P. iuterruptus Lee. —Moderately elongate, parallel, reddish brown, 

 each elytron with a large central black area extending from the side margin to 

 the second interspace, its posterior limit transverse, its anterior outline quite 

 strongly oblique, extending from just behind the humerus to a point on the 

 suture about one-third from the base. Eyes strongly globose, much more promi- 

 nent than the sides of the prothorax, the front between them subequal in width 

 to their vertical diameter, or to the united lengths of the second and third 

 antennal joints. Antennae nearly as long as the entire body, subserrate, the 

 tenth joint in the male three times as long as wide. Prothorax not very closely 

 granulate, not distinctly tuberculate, strongly constricted posteriorly, confusedly 

 hirsute with yellowish and brownish hairs, the latter predominating on the disk, 

 the former at the sides. Elytra twice as wide as the prothorax and fully three 

 times as long, humeri prominent, sides parallel, very slightly wider at apical 

 third; strial punctures moderate, finer posteriorly, interspaces evidently wider 

 than the strise, each with a row of suberect bristles 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 subtriangular basal area, 

 suture and apical third or fourth clothed sparsely with recumbent hairs, pale 

 yellow, varying to whitish along the anterior and posterior margins of the black 

 fascia, where they are condensed into fairly conspicuous bauds; an oblique discal 

 dash of similar hairs extending forward from the second interspace across the 

 third and fourth, the surface beneath this dash usually of paler color like the 

 suture. Metasternum and abdomen polished, very finely, sparsely punctulate, 

 with scattered coarser punctures; finely, not densely pubescent. Metasternum 

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

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