124 MEMOIRS ON THE COLEOPTERA 



Laemophlceus fraterculus n. sp. Female oblong, distinctly convex, 

 highly polished, pale flavo-testaceous throughout, the elytra infumate at 

 least posteriorly; hairs small, sparse and inconspicuous; head almost as 

 wide as the prothorax, rather strongly but loosely punctate, not striate 

 along the median line, the ambient line narrowly interrupted at the middle 

 anteriorly; labrum short, rounded; eyes well developed, about at the 

 base, globularly convex, moderately faceted and with infinitesimal erect 

 setae; antennae extending to basal third of the elytra, slender, the 3-jointed 

 club distinctly dilated, joints four to eight smallest, subequal, each much 

 shorter than the second, which is a little shorter than the third, the basal 

 joint subcylindric, very moderate in size; prothorax short, about twice 

 as wide as long and rather less than a third as long as the elytra, the 

 sides perfectly even, not undulated, parallel in apical half, thence sinu- 

 ously converging to the prominent basal angles; surface rather strongly, 

 moderately closely punctate, finely and sparsely outside of the sublateral 

 lines and also having an impunctate median line; scutellum with very 

 few minute punctures; elytra nearly one-half longer than wide, much wider 

 than the prothorax, circularly rounded posteriorly, the parallel sides 

 rather strongly arcuate; surface of each with four distinct striae, the 

 intervals with sparse moderate punctures, sometimes in part biserially 

 arranged, the sublateral carina of the preceding group wanting; abdomen 

 finely, sparsely punctulate. Length (9) 1.8 mm.; width 0.75 mm. 

 Pennsylvania (Buena Vista Spring, Franklin Co.). 



Readily distinguishable from adustus Lee., by the sparser punc- 

 tures and much larger head in the female. In adustus ( 9 ) the 

 punctures of the head and pronotum are smaller and much closer 

 than in fraterculus, the head not so large and the eyes smaller, abruptly 

 more prominent and at a considerable distance from the base; the 

 scutellum, basal joint of the antennae and basal angles of the pro- 

 thorax are as in fraterculus. In the male of this peculiar section of 

 the genus the antennae are finely filiform throughout and about as 

 long as the elytra, the head across the eyes about as wide as the 

 prothorax and the eyes very moderate, slightly in advance of the 

 base and globularly prominent. Adustus was described from eastern 

 Pennsylvania and I have examples at hand from Virginia (Norfolk) 

 to Maine (Wales), Frost. 



The section of Lcemophlceus represented at present by convexnlus 

 Lee., is also aberrant. The mandibles in the male are long, promi- 

 nent and but slightly arcuate, the eyes in that sex very prominent 

 and hemispherical, while in the female they are larger and less 

 prominent. The epistomal suture is more or less broadly interrupted 

 medially in the male, though generally subentire in the female, and 

 the frontal margin in both sexes is feebly sinuato-truncate through-
