P. mormonica n. sp. — Rather broad, somewhat shining, the ahdomen 

 polished, dark rufo-piceous in color, the abdomen black throughout ; legs dark, 

 rufescent ; antennae black, pale toward base ; head and pronotum minutely, 

 not densely, evenly punctate, the elytra hardly less minutely and rather more 

 sparsely, but more distinctly so ; abdomen finely, evenly, somewhat closely 

 punctate throughout, and with somewhat well-marked imbricate sculpture ; 

 pubescence short, subrecumbent, rather dense but not conspicuous, longer 

 and sparser on the abdomen. Head small, nearly as Song as wide, slightly 

 more than one-half as wide as the prothorax, the eyes at about one-half of 

 their length from the base ; antennae about as long as the head and prothorax, 

 the first three joints subequal in length, the first stouter, cylindrical, third 

 one-half longer than the fourth which is distinctly longer than wide, fifth 

 subquadrate, joints five to ten gradually and rapidly broader, the tenth twice 

 as wide as long, eleventh as long as the two preceding, moderately pointed at 

 apex. P)-othorax three-fourths wider than long, the sides rounded and parallel 

 near the base, then strongly convergent and nearly straight to the apex ; basal 

 angles very obtuse and blunt ; base broadly evenly and strongly arcuate, 

 much wider than the subtruncate apex : disk strongly convex, perfectly even, 

 unimpressed. Elytra two-fifths wider than long, at apex about one-fifth wider 

 than the prothorax, nearly one-half longer than the latter : humeri obliquely, 

 feebly rounded externally ; disk broadly, indefinitely impressed behind the 

 scutellum. Abdomen at base quite distinctly narrower than the elytra, much 

 longer than the anterior parts. Length 2.7 mm. ; width 0.8 mm. 



Utah (Provo). Mr. H. F. Wickhara. 



The single type before me is a male, having a long distinct carina 

 on the fifth tergite and another, only slightly shorter, on the sixth; 

 elytral angles and second segment not in the least modified. 



GNYPETA Thorns. 



A genus allied to Tachyusa and comprising but few species at 

 present. 



G. atrollicens n. sp. — Polished, intense black, throughout; base and 

 apex of the tibiae and tarsi paler ; antennae not paler at base ; pubescence 

 not very dense, short, stiff, erect, pale brown in color and not conspicuous. 

 Bead slightly wider than long, finely, sparsely punctate, the vertex broadly, 

 feebly impressed in the middle; eyes large, somewhat convex, setose, at less 

 than their own length from the base ; tempora broadly rounded at base to the 

 very wide neck ; antennae long, slender, feebly incrassate, nearly two-fifths as 

 long as the body. Prothorax about one-third wider than long, widest at apical 

 third where the sides are narrowly rounded and somewhat prominent, thence 

 feebly convergent and distinctly sinuate to the basal angles, the latter obtuse 

 but not rounded ; base broadly arcuate, wider than the apex ; disk convex, 

 feebly impressed in a transversely oval discal area before the scutellum. 

 Elytra nearly one-half wider and longer than the prothorax, moderately trans-
