to slightly rounded angles; anterior impression deep; foveae deep, 

 prolonged anteriorly to beyond the middle at some distance from 

 the sides; elytra three-fifths longer than wide, slightly less than 

 twice as wide as the prothorax, very gradually ogival behind, the 

 sinus short and very shallow, the suture not at all mucronate at 

 apex, rounded; striae fine, groove-like, abruptly coarser along the 

 apex; intervals flat; anterior puncture near the third, the two 

 posterior near the second, stria; met-episterna much elongated; 

 anterior male tarsi rather distinctly dilated; tarsi long and slender, 

 the ungues rather long. Length (cf 9) 8.5 mm.; width 3.2-3.3 

 mm. Mexico (Guerrero), — Baron. Communicated, with many 

 other species, by Mr. W. G. W. Harford. Five specimens. 



*harfordi n. sp. 



Form less stout than in brunneomarginatus and much smaller in size, 

 similarly ventricose and somewhat more so than in harfordi, shining, 

 piceous-black, the margins faintly and narrowly diaphanous; under 

 surface piceo-rufous, the legs pale brownish-flavate; head slightly 

 and obtusely elongate, more than three-fourths as wide as the pro- 

 thorax, with well developed and rather prominent eyes; antennae 

 not very slender, distinctly less than half as long as the body, pale 

 rufous in color throughout; prothorax a third wider than long, 

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

 rapidly sinuate basally and rectilinear and parallel in basal seventh, 

 the angles right, sharply defined but not prominent; base very 

 feebly arcuate, as wide as the moderately sinuate apex, the apical 

 angles rather bluntly pointed; margins broadly, subequally reflexed 

 throughout though not quite so broadly as in brunneomarginatus, 

 the surface throughout nearly as in that species, except that the 

 fovese are slightly less impressed and with fine and feeble rugulosity; 

 elytra oblong, with feebly arcuate sides, which are rapidly and 

 widely rounded at base, three-fifths longer than wide and nearly 

 twice as wide as the prothorax, gradually ogival behind, with long 

 and distinct sinus; striae moderately fine, grooved, smooth, coarser 

 at apex; intervals flat, the three punctures moderate; sutural 

 angles not micro-mucronate; anterior male tarsi narrowly dilated. 

 Length (cf) 8.6 mm.; width 3.2 mm. Arizona (Pinal Mts.), — 

 Wickham. A single example pinalicus n. sp. 



25 — Body rather stout, the surface rather depressed, highly polished, 

 black, the legs piceous; side margins not distinctly paler; head 

 rhomboidal, barely longer than wide, three-fourths as wide as the 

 prothorax and with large and somewhat prominent eyes; occiput 

 nubilously rufous at the middle; surface rufescent anteriorly, the 

 impressions long, parallel, narrow, deep and irregularly sinuous; 

 antennae not very slender, half as long as the body, testaceous, the 

 joints feebly infumate at their apices; prothorax nearly a third 

 wider than long, widest anteriorly, the sides broadly and strongly 

 reflexed, strongly rounded, becoming oblique and nearly straight 

 in about basal half, feebly sinuate just before the angles, which are 

 right and sharply defined; base transverse and strongly beaded, 

 rather wider than the sinuate and more finely beaded apex; surface
