Coleojoferological Notices, VI. 591 



legs pale, the tip of the hind femora but slightly darker above; aiitennaj tes- 

 taceous, the eleventh joint slightly darker; pnbescence cinereous, extremely 

 short, fine, decumbent and sparse, without trace of erect hairs. Head two- 

 thirds as wide as the prothorax, more shining, the sculpture feebler, finely, 

 feebly punetulate, the impressions large and deep, not coalescent behind, the 

 epistoma short; labrum transverseand very broadly rounded; eyes large, prom- 

 inent and basal; antennte one-fourth longer than the prothorax, very feebly 

 incrassate toward apex, the tenth joint evenly triangular, nearly as long as 

 wide, fifth sensibly dilated. Prothorax barely three-fifths wider than long, the 

 sides parallel, evenly and feebly arcuate, becoming slightly sinuate toward the 

 basal angles, which are right and not rounded; apical angles slightly acute, ad- 

 Aanced and not blunt; apex broadly emarginate; base with a very broad and 

 feeble arcuate lobe; disk finely and sparsely but distinctly punctate. Elytra 

 two-thirds longer than wide, one-fourth Avider than the prothorax, very feebly 

 and gradually dilated behind, the apex evenly rounded; lateral edges reflexed; 

 sutural angles acute and posteriorly prominent; disk strongly and rather 

 closely punctate, less distinctly so toward apex. Abdomen polished, somewhat 

 sparsely clothed with short and fine cinereous j)ubescence. Length 3.5 mm. ; 

 width 1.4.'i mm. 



California,. 



The type of this species is a female, differing from the female of 

 sculptilis in having the submarginal impressed line of the pronotum 

 abruptly ending at about apical fifth of the length. The fifth ven- 

 tral is truncate as in sculptilis. 



VECTURA n. gen. 



In this genus the body is cuneiform, with the head small and 

 more elongate than usual, the antennae being moderate in length, 

 scarcely serrate and feebly incrassate at apex, the eyes situated 

 before the base of the head and slightly elongate, and the pro- 

 thorax more or less constricted near the apex, with the basal an- 

 gles acute and prominent. It resembles Allonyx to some extent 

 in the form of the epipleuri^, these being rather wide, flat, subhor- 

 izontal and pubescent, but, unlike those of Allonyx, becoming 

 gradually narrow behind the middle. The inner claw has a very 

 long and rather thick corneous expansion and the membranous 

 appendage is correspondingly shortened but extends to the tip of 

 the claw. The tibia* are devoid of spinules as usual in this group. 

 The two species known to me may be distinguished as follows : — 



Pubescence not entirely concealing the integuments; ])rothorax strongly con- 

 stricted behind the apiciil angles, which are very acute and prominent later-
