L. picea Horn. — Trans. Am. Ent. Soc, 1872, p. 144— A specimen before 

 me from Gilroy, Santa Clara Co., appears to satisfy the description given by 

 Dr. Horn for this species; it is, however, rather smaller and the pro thorax 

 appears to be slightly less strongly transverse than shown in the figure and 

 described in the text; it is two-thirds wider thin long at apex and nearly 

 two and one-half times as wide as long at base. 



L. polita n. sp. — Narrowly oval, strongly convex; black; legs and palpi 

 dark piceo-testaceous; upper surface polished, with l-ather long, recumbent, 

 very fine and sparse pubescence; uuder surface black, rather densely pubes- 

 cent. Head one-half wider than long, feebly convex, very feebly reticulate, 

 excessively minutely and rather sparsely punctate; epistomal suture trans- 

 verse, we 1 marked; last joint of maxillary palpi darker in color. Prothorax 

 at apex just visibly wider than the head, at apex broadly and very feebly 

 emarginate, two-fifths wider than long; base two and one-third times wider 

 than the median length, transversely truncate, broadly and very feebly sin- 

 uate on each side of the scutellum, and very feebly and anteriorly oblique at 

 the sides; sides feebly and evenly arcuate; disk evenly convex, very feebly 

 reticulate, very minutely, s-parsely punctate, with a transverse row of dense 

 punctuation at the apex on each side. Scutellum distinctly wider than long, 

 sidts feebly arcuate. Elytra at base equal in width to the prothorax; sid< s 

 strongly convergent aud rather strongly and evenly arcuate to the apex, 

 which conjointly is not truncate, but rather acutely rounded; each elytron at 

 apex rather acute aud very distinctly rounded; disk strongly convex, scarcely 

 two and one-half times as long as the prothorax, finely and very distinctly 

 reticulate, more finely and densely so than the pronotum, not visibly punc- 

 tate. Legs rather slender. Eighth segment with two apical setae. Length 

 1.4 mm. 



California; (San Francisco). Several specimens. 

 May be distinguished by its blackness, polished integu- 

 ments and elytral structure. 



L. angUStllla u - sp. — Narrowly oval, strongly convex, piceous-bl >ck; legs 

 and palpi dark piceous-brown; pubescence very fine, not dense; integuments 

 shining. Head one-half wider than long, feebly convex, not visibly reticu- 

 late, very minutely aud sparsely punctate; epistomal suture very feebly ar- 

 cuate toward the eyes; last joint of maxillary palpi scare ly at all darker in 

 color. Prothorax at apex not wider than the head, broadly, very feebly sin- 

 uate, two-fifths wider than long; base transversely truncate, almost perfectly 

 straight, two and one-fourth times as wide as the median length; sides feebly 

 and evenly arcuate; disk not visibly reticulate, excessively minute ly, sparsely 

 punctate, with a feeble row of larger and denser punctiform subasperate ero- 

 sions on each side behind the apical margin, and, near the basal margin, two 

 small impressed punctures distant by s-lightly more than the width of the
