and the legs pale; upper surface almost glabrous; head two-thirds 

 as wide as the prothorax, finely but strongly, loosely punctate, the 

 eyes moderate in size, rather prominent; antennal club pale, very 

 broad, oblong-oval; prothorax only about one-half wider than long, 

 somewhat narrowed from the base to apex and having slightly 

 arcuate sides, the apex rather strongly arcuate, sinuate near each 

 anteriorly prominent and acute angle, the punctures rather small, 

 deep and widely separated; strides completely obsolete; elytra 

 two-thirds to nearly three-fourths longer than wide and obtusely 

 parabolic posteriorly, very slightly wider than the prothorax and 

 two and one-half times as long, the sides feebly arcuate, rather more 

 prominently so near basal third; punctures small but deep, widely 

 spaced in even approximate series, obsolescent apically; under sur- 

 face finely pubescent and densely punctulate. Length 2.5-3.3 mm.; 

 width 1.05-1.35 mm. Indiana, Pennsylvania and North Carolina 

 (Asheville). [Ips 4-mac. Say] quadrimaculata Say 



Form much more abbreviated, smaller, not so shining, the hairs small 

 and decumbent but distinct; color pale ferruginous, blackish except 

 posteriorly beneath, the elytra piceous-black, broadly rufous at base, 

 more briefly behind the scutellum and each with a large oval postero- 

 external, more nubilous rufous spot, which sometimes almost disap- 

 pears; head two-thirds to three-fourths as wide as the prothorax, 

 finely, closely punctate, the eyes moderate in prominence but rather 

 large; prothorax very much shorter than in the preceding, fully 

 three-fourths wider than long, the sides subparallel and distinctly 

 arcuate, the marginal bead thick; apex strongly arcuate in the 

 middle, more advanced than the angles, the sinuses near which are 

 generally feeble; punctures deep, dense laterally, rather smaller and 

 not so close medially; surface broadly, feebly impressed at base at 

 each side of the middle, the usual strioles, however, wanting; elytra 

 parallel and about as wide as the prothorax, barely one-half longer 

 than wide, very broadly and obtusely rounded behind, nearly three 

 times as long as the prothorax, the punctures strong, well separated 

 in partial series which, as usual, are wholly unimpressed but in 

 great part confused in arrangement antero-externally and minute 

 posteriorly, though traceable almost to the apex; abdomen finely, 

 closely punctate, the metasternum more coarsely, though wholly 

 impunctate at its posterior margin. Length 2.4-2.7 mm.; width 

 i.o-i.i mm. Utah (Provo), Wickham uteana n. sp. 



7 Body elongate-subrhomboidal, convex, rather shining, ferruginous, 

 the elytra slightly darker though broadly clear toward the humeri, 

 the abdomen dark brown, the legs and abdomen, posteriorly, pale; 

 pubescence rather long, decumbent and distinct; head three-fourths 

 as wide as the prothorax, finely, rather closely punctate, the eyes 

 moderately large and prominent; third antennal joint longer than 

 the next two combined, the eighth as wide as long, regularly obtri- 

 angular and wider than the preceding, the club broad and oblong, 

 of the usual structure; prothorax relatively smaller than usual, 

 nearly four-fifths wider than long, the sides converging from the 

 base and nearly straight, a little more convergent apically, the
