2. L.. iuterstitialis n. sp. — Elongate-oval, convex, polished, black, 

 the elytra with greenish, the pronotuni with subcupreous metallic reflection; 

 legs black; antenna? black, the second joint and the third less distinctly tes- 

 taceous; pubescence moderately short, sparse, denuded on each elytron in two 

 large spots in basal half and several confused spots behind the middle especi- 

 ally toward the suture. Head three-fifths as wide as the prothorax, sparsely 

 but deeply perforato-punctate, feebly granulato-reticulate, obsoletely biim- 

 pressed toward apex; eyes moderately prominent; antenna; qiiite distinctly 

 longer than the prothorax, rather slender, feebly iucrassate. ProtJwrax 

 scarcely more than one-third Avider than long, widest near basal two-fifths; 

 sides broadly rounded toward base, thence strongly convergent and nearly 

 straight to the apex, the latter sinuato-truncate and scarcely two-thirds as 

 wide as the base; angles obtuse but scarcely at all rounded; disk evenly con- 

 vex, deeply but sijarsely perforato-punctate, the interspaces flat and finely and 

 evenly granulato-rugose, coarsely rugose near the sides. Scutellum densely 

 clothed with white pubescence. Elytra fully four-fifths louger than wide, 

 slightly wider than the prothorax, the sides parallel and nearly straight, 

 rather rapidly parabolic in less than apical third ; disk coarsely, deeply punc- 

 tate, somewhat rugose by oblique light, the punctures well separated, smaller 

 toward apex. Under surface finely but strongly rugose, the abdomen reticu- 

 late with fine lines toward apex. Legs moderate, the hind tarsi subequal in 

 length to the tibia;. Length 3.3 mm. ; width 1.2 mm. 



California (Sonoma Co.). 



This species and the preceding are distinguished from all 

 others of the genus b}' the peculiar sculpture of the pronotum, 

 and interstitialis differs from rotuiuUcollis in its longer and less 

 convex elytra, longer pubescence, color of the antenna? and pecu- 

 liarities of thoracic structure previously stated. It is represented 

 by a single female specimen.

Subparallel, elongate, moderately- stout and convex, polished

 long, moderately coarse and sparse, rather indefinitely denuded in 

 numerous large rounded spots on the elytra. Head slightly more
