FALL AND COCKERELL. 231 



fourth and of equal widtli ; outer angle of third joint somewhat acute, that of the 

 fourth and following joints nearly right. Head densely, rather coarsely umbili- 

 cate-pnnctate, front broadly concave, apical margin not reflexed. Prothorax 

 distinctly elongate, sides feebly arcuately convergent anteriorly, scarcely sinuate 

 before the hind angles, which are not or but just visibly divergent, surface 

 densely, rather coarsely unibilicate-punctate throughout, hind angles not cari- 

 nate. Elytra and lower surface as usual. First joint of hind tarsi a little longer 

 than the next two; third joint with a broad well developed lobe, fourth joint not 

 lobed. Length 9.5 mm.; width 2.5 mm. 



Southern California, Santa Monica (Albright). 



This species resembles superficially certain species of Agriotes. 

 The frontal margin is less produced than in typical Athous, but is 

 well defined, and the lobe of the third tarsal joint is unusually well 

 developed ; these differences are of degree merely, and the generic 

 reference seems unavoidable. 



Athous rufotesilaceiis n. sp.— J/oZe.— Form very slender, not very con- 

 vex, rufotestaceous, elytra slightly paler; pubescence very fine, sparse and incon- 

 spicuous, surface strongly shining. Antennpe slender, the eighth joint attaining 

 the hind angles of the prothorax; second joint nearly one-half as long as the 

 third, the latter equal to the fourth ; fourth joint widest, but scarcely more than 

 half as wide as long. Head coarsely closely umbilicate-punctate, front deeply 

 triangularly impressed. Prothorax evidently longer than wide, sides nearly 

 straight and parallel, a little convergent before the front angles, very slightly 

 sinuate before the hind angles, which are a little divergent; disk bi-impressed 

 near the base, surface moderately coarsely punctate, the punctures separated 

 from one-half to their own diameters at the middle, a little closer at sides ; hind 

 angles not carinate. Elytra very nearly three times as long as the prothorax, 

 finely striate, striae rather closely punctate, interspaces more sparsely finely punc- 

 tate. Beneath more obviously but sparsely pubescent ; presternum closely 

 strongly punctate, metasternum and abdomen more finely punctate; first joint 

 of hind tarsi as long as the next two. 



Female. — Stouter and more convex than the male, antenuse shorter and less 

 slender, barely reaching the hind angles of the prothorax, sides of the latter 

 more rounded, elytra a little wider posteriorly. 



Length 10.5-12.5 mm.; width 2.5-3.6 ram.; the larger measurements for the 

 female. 



Beulah, 3 examples (Cockerell). 



Most nearly related to cribratus, from which it dififers in its less 

 coarsely and densely punctured prothorax, and more slender antennae 

 of the male. In cribratus the fourth antennal joint is three-fourths 

 as wide as long or very nearly so ; the color is piceous throughout in 

 the male of fully colored specimens, the elytra paler in the female. 



Athous jejiinus n. sp. — Male. — Slender, piceous-brown, elytra slightly 

 paler, moderately shining, pubescence rather long and plentiful, ochreo-cinereous 

 in color. Antennae surpassing the hind angles of the thorax by three and one-
