96 Memoirs on the Coleoptera 



A — General characters, color, lustre and sculpture as in variolata, but 

 with the elytra notably shorter and more oval, the sides more 

 arcuate; sides of the pro thorax usually somewhat less arcuate, 

 the apical angles still blunter, the basal rather less broadly 

 rounded. Length (d^ 9) 5-6-5.8 mm.; width 2.15-2.25 mm. 

 California (San Diego), — Ricksecker coronadina n. subsp. 



Form oblong-suboval and moderately convex, larger and stouter than 

 variolata, shining, black, with the faintest subaeneous lustre anteri- 

 orly, the elytra piceous, with paler sides; legs rufo-piceous; head 

 as in the preceding, though a trifle larger and more elongate; antennae 

 much longer, black, with piceo-rufous first joint, four-sevenths as 

 long as the body; fourth palpal joint still more elongate, one-half 

 longer than the third; prothorax nearly one-half wider than long, 

 the perfectly parallel sides evenly and less strongly arcuate from 

 apex to base, the basal angles very obtuse but not so rounded as 

 in the preceding; surface and margins nearly similar; elytra one- 

 half longer than wide, only one-half wider than the prothorax, the 

 sides as in variolata and similarly very finely reflexed, but with the 

 apex rather more rapidly rounded and obtuse, the sinus longer 

 though feeble; striae very fine, the intervals not quite so flat, the 

 six punctures of the third much smaller and less conspicuous; 

 epipleura flavate, the rest of the under surface deep black; tarsi 

 very slender. Length (9) 6.5 mm.; width 2.45 mm. California 

 (Siskiyou Co.), — Koebele shastanica n. sp. 



7 — Sinuate basal margin of the elytra forming an obtuse, rather blunt 

 but anteriorly projecting angle with the side margin; elytral inter- 

 vals not, or only feebly or irregularly, alternating in width 8 



Sinuate margin joining the sides in a broad and even curve 9 



8 — -Form moderately stout, slightly convex, highly polished throughout 

 and black, with the feeblest piceous tinge; under surface piceous, 

 the legs dark rufous; head about four-fifths as wide as the pro- 

 thorax, slightly elongate, with large and somewhat prominent eyes, 

 the anterior impressions very small and feeble; last palpal joint 

 but slightly longer than the third; antennae piceous-black, with only 

 slightly paler basal joint, rather stout, becoming more slender 

 toward the first joint, barely half as long as the body, the third 

 joint much longer than the fourth, the fifth two and one-half times 

 as long as wide; prothorax one-half wider than long to a little less, 

 widest well before the middle, the sides rather strongly rounded, 

 less so and distinctly oblique posteriorly, finely reflexed, more so 

 basally, the angles very obtuse and blunt; base broadly, obliquely 

 rounded from seta to seta, as wide as the apex, which is feebly 

 sinuate and with rounded angles; transverse impressions obsolete; 

 anterior discal foveae wholly wanting, the stria fine; foveae large, 

 irregular and very shallow, smooth; elytra oblong and parallel, 

 with feebly arcuate sides, gradually more rounding basally, nearly 

 three-fifths longer than wide, four-fifths wider than the prothorax, 

 rather rapidly rounded at apex, with the sinus subobsolete or 

 barely traceable; striae fine, smooth, impressed; intervals sub- 

 equal, feebly convex; met-episterna more than twice as long as
