brown tbrougboat, the antennae dark,paler toward base ; surface dull, the 

 head and prothorax strongly micro- reticulate, each of the minute and 

 rather close-set punctures at the centre of a somewhat larger polygon, 

 the elytra more shining, feebly reticulate, closely, somewhat asperately 

 and more distinctly punctate, the abdomen only reticulate toward tip, 

 finely, rather closely punctate; pubescence short, not conspicuous; 

 head and antennae as in reptans, the former smaller in size, the eyes 

 rather less prominent; prothorax about a fourth wider than long and 

 nearly a third wider than the head, the sides subparaliel, broadly arcu- 

 ate anteriorly, very feebly converging and straight toward base, the 

 basal angles slightly obtuse and narrowly rounded; surface very obso- 

 letely, transversely impressed before the scutelium; elytra about a fifth 

 or sixth wider and a third longer than the prothorax, the humeri very 

 slightly exposed at base; abdomen parallel, much narrower than the 

 elytra, the first four tergites subequally impressed at base. Length 2.6 

 mm.; width 0.62 mm. Oregon (The Dalles), — H. F. Wickham. 



oregona n. sp. 

 Form very slender, parallel, convex, shining, blackish-piceous, the elytra 

 gradually rufous posteriorly, the abdomen wholly black; legs brown, 

 the antennae fuscous, slightly paler basally; integuments very obsoletely 

 micro-reticulate, the elytra not at all so, the abdomen only reticulate 

 toward tip; head large, fully as long as wide, abruptly constricted at 

 base, the eyes well developed and rather prominent; antennae moder- 

 ately incrassate distally, but little longer than the head and prothorax, 

 the outer joints transverse; prothorax scarcely as wide as the head, as 

 long as wide, parallel, the sides broadly rounded anteriorly, thence 

 very feebly converging and nearly straight to the distinct basal angles, 

 the punctures, like those of the head, fine and sparse, the surface not 

 at all impressed at any point; elytra fully a third wider and a fourth 

 longer than the prothorax, the humeri well exposed at base, the punc- 

 tures moderately fine but very distinct, somewhat close-set; abdomen 

 perfectly parallel to the tip of the fifth segment, with straight sides, 

 distinctly narrower than the elytra, finely, moderately closely punctate, 

 the first three tergites strongly, the fourth more narrowly and less 

 deeply impressed at base. Length 1.85 mm.; width 0.42 mm. Iowa 

 and North Carolina soblaevis n. sp. 



The genus JPhloeopoi-a, as generally recognized, is some- 

 what composite. The general facies, for example, of reptans 

 or the allied oregona, on the one hand, and sublaevis or the 

 nearly allied European corticalis on the other, being quite 

 different and the last has only the first three tergites im- 

 pressed at base. Ferruginea differs much in general appear- 

 ance, because of the more strongly converging sides of the 

 prothorax toward base, but is evidently more closely allied to 

 the reptans than to the corticalis group of the genus. Sub- 

 laevis was formerly identified by me as latens Er., but as this
