very feebly sinuate at each side, two and one-third times as wide as long; 

 sides evenly and feebly arcuate; basal angles from above narrowly rounded; 

 disk very broadly couvex, finely reticulate and subgranulose; punctures ex- 

 cessively minute, rather sparse and scarcely \isible. Scutellum very small, 

 twice as wide as long, parabolicully rounded behind throughout. Elytra at 

 base slightly, but distinctly narrower than the prothorax; sides not strongly 

 convergent, evenly and moderately arcuate to the apex, which, conjointly is 

 obtusely and evenly rounded, not at all truncate; inner angles narrowly but 

 distinctly rounded; disk two-fifth3 longer than wide, two and one-half times 

 as long as the pronotum, moderately convex, reticulate and subgranulose 

 like the pronotum, excessively minutely and scarcely visibly punctate. 

 Eighth segment having a long, robust apical style, with one or two short ro- 

 bust spinules on eithtr side. Leugth 1.6 mm. 



California; (Mendocino Go. 1). 



Easily distinguished by its wider prothorax and distinctly 

 alutaceous surface sculpture. The maxillary palpi are dis- 

 tinctly more slender than in the following species: 



L. congener m sp. — Narrowly oval, rather convex, black; legs piceons; 

 pubescence fine, sparse; integuments shining, very feebly subalutaceous. 

 Head feebly convex, finely, evenly and distinctly punctate; epistomal suture 

 transverse, distinct, slightly arcuate and very fine near the eyes. Prothorax 

 at apex just visibly wider than the head; proportions nearly as in alutacea; 

 sides evenly and more feebly arcuate; apex more feebly and arcuately emar- 

 ginate; di.-k broadly convex, finely, densely reticulate; finely, evenly and 

 distinctly punctate. Scutellum triangular, apex not rounded, three-fourths 

 wider than long. Elytra at base fully as wide as the prothorax; sides col- 

 vergent, evenly and not strongly arcuate to the apex, which, conjointly is 

 obtusely and evenly rounded, not at all truncate; inner angles very narrowly 

 rounded; disk nearly two and one-half times as long as the prothorax, mod- 

 erately convex, more finely and densely reticulate than the pronotum, not 

 perceptibly punctate. Eighth segment with a long anal style and two short 

 spinules on each side. Length 1.6 mm. 



California; (Mendocino and Humboldt Cos.). Several 

 specimens. 



This species is closely allied! to alutacea, but differs in its 

 more evenly oval and narrower form, its relatively narrower 

 prothorax, much more shining surface, stronger and more 

 evident pronotal punctuation, shorter, more robust maxillary 

 palpi, and particularly in the form of the scutellum. The 

 two discal punctures of the epistoma are slightly stronger,
