deep, basal depressions; surface finely, densely, irregularly punc- 

 tate, with numerous irregular, smooth areas, and each elytron orna- 

 mented with long, recumbent, yellowish-white pubescence as fol- 

 lows: A few scattered hairs on basal third; a broad, more or less 

 distinct, irregular, transverse fascia at middle; and a similar fascia 

 covering the apical fourth. 



Abdomen beneath densely, obsoletely reticulate, sparsely, feebly, 

 ocellate-punctate, the punctures oblong, open posteriorly, a short, 

 recumbent, white hair arising from each puncture; last segment 

 broadly, obtusely rounded at apex, with the margin entire, and the 

 apical groove deep, transversely truncate posteriorly, and follow- 

 ing the outline of the lateral margin on each side. 



Length, 3.5 mm; width, 1.7 mm. 



Type locality. — Tejupilco, Mexico, D.F. 



Type.— U.S.N.M. No. 49572. 



Remarks. — Described from a unique male collected at the type 

 locality at an altitude of 3,900 feet, during July 1932, by H. E. 

 Hinton. 



This species resembles 7iever77ianni Fisher, but it differs from 

 that species in having the epistoma transverse between the antennal 

 cavities, the pronotum subequal in width to the elytra and without 

 distinct prehumeral carinae, and the pubescence on the elytra uni- 

 formly yellowish white. 



BRACHYS LINEIFRONS, new species 



Female. — Broadly cuneiform, twice as long as wide, broadly 

 rounded in front, slightly narrower behind than in front, mod- 

 erately shining, the elytra ornamented with silvery white pubescent 

 spots; above dark brown, with more or less distinct purplish, 

 aeneous, and greenish reflections in certain lights; beneath piceous, 

 with a feeble aeneous reflection. 



Head feebly convex, broadly, longitudinally depressed, without 

 gibbosities on the vertex, but with a narrow, longitudinal groove 

 extending from occiput to near the epistoma; surface feebly, finely 

 reticulate, sparsely punctate, and very sparsely, irregularly clothed 

 with long, semierect, whitish and yellowish hairs; epistoma rather 

 narrow between the antennal cavities, the sides feebly elevated, 

 but not transversely carinate in front. 



Pronotum moderately convex, slightly more than twice as wide 

 as long at middle, distinctly narrower at apex than at base, widest 

 at base; sides obliquely narrowed from base to apical angles; when 

 viewed from the side the lateral margin slightly sinuate anteriorly, 

 and more strongly arcuate near the posterior angle for the recep- 

 tion of the anterior leg; anterior margin transversely truncate;
