338 MEMOIRS ON THE COLEOPTERA 



lower apically, the scutellar very short; intervals strongly convex through- 

 out the width, less so apically; metasternal sides, and the abdomen latero- 

 basally, with small and very feeble sparse punctures. Length (d") 6.8 

 mm.; width 2.65 mm. California (locality unknown; the label reads 

 '"Cal.," with a vertical red line to the left). 



This species was erroneously described under the name "fuchsi 

 Schf." (Mem. Col., IV, 1913, p. 128). The basal thoracic angles 

 in fuchsi are described as obtuse, and the size is materially larger; 

 fugax is much smaller and slightly stouter than longicollis Lee., and 

 with feebler sinuation of the sides of the prothorax before the basal 

 angles. 



Leptoferonia inopina n. sp. Body moderately stout, oblong-suboval, 

 convex, shining, piceous-black, the under surface and legs dark rufous; 

 head elongate, two-thirds as wide as the prothorax, the eyes rather large 

 but only moderately prominent; anterior sulci strongly converging; an- 

 tennae obscure testaceous, rather strongly compressed, slender on the 

 narrow side, extending slightly behind the thoracic base; prothorax 

 widest near apical third, fully as long as wide, rather narrower poster- 

 iorly than in the preceding; base feebly sinuate medially, transverse, 

 margined only in lateral fourth and evidently narrower than the apex, 

 which is subsinuously truncate; sides rather strongly rounded anteriorly, 

 gradually less arcuate and broadly oblique thence to the basal angles, 

 which are obtuse and slightly rounded, not in the least prominent; im- 

 pressions feeble, the posterior evident, the stria finely impressed, not en- 

 tire; subbasal fovea rather long, finely, deeply impressed, linear and longi- 

 tudinal; posterior marginal puncture far before the hind angles; elytra 

 nearly two-thirds longer than wide, barely a fifth wider than the pro- 

 thorax, rapidly obtusely rounded behind, the sides feebly arcuate, more 

 so basally, the humeri scarcely denticulate; stria? even throughout, rather 

 deeply impressed, the scutellar very short; intervals rather strongly con- 

 vex; prosternal process not evidently margined. Length (c? 1 9 ) 8.0-8.5 

 mm.; width 2.8-2.9 rnm. Oregon (Josephine Co.), Nunenmacher. 



This is a remarkably isolated species in the longicollis subsection, 

 in having the posterior lateral thoracic puncture far before the basal 

 angle as in Ferestria obsoleta Say, and it differs greatly from fuchsi, 

 humilis and fugax in having the base not margined except at the 

 sides; from longicollis it differs at least in the obtuse and slightly 

 rounded basal angles of the prothorax. 



Gastrellarius n. gen. 



The species of this genus are small, peculiarly ventricose, with 

 deep elytral striae and a single dorsal puncture, on the third interval 

 near the second stria and more or less near the middle of the length;
