L.. aterriiuus n. sp. — Oval, about two-thirds longer than wide, strongly 

 convex ; sides very feebly convergent behind from near the base of the elytra; 

 intense black throughout above, paler, piceous beneath, the legs and antennae 

 flavate ; shining. Head not reticulate, very minutely and rather sparsely 

 punctate ; eyes moderate ; antennae rather short, third joint elongate, obconi- 

 cal, rather longer than the next two, four to eight very short, compact ; club 

 small and slender, about as long as the preceding seven joints combined, ninth 

 just visibly longer and wider than the tenth, eleventh oval, a very little longer 

 than wide, shorter than the two preceding. Prothorax rather short, more than 

 twice as wide as long, extremely minutely and obsoletely punctate, not at all 

 reticulate, the basal lobe broad and rather strong, the marginal bead almost 

 completely obsolete. Scutellum triangular, two-thirds wider than long. Elytra 

 rather more than three times as long as the prothorax, evenly and somewhat 

 narrowly rounded at the apex ; discal stria; very fine, vanishing at basal third, 

 the first continuous to the apex, the second approaching very near but not 

 joining the first at apical fifth or sixth ; disk coarsely reticulate in very wavy 

 broken lines, having distant regular rows of small widely-spaced crescentiform 

 and very feeble punctures, which become slightly wider and stronger near the 

 sides, the punctures of the intervals almost completely obsolete. Legs mode- 

 rate ; posterior tibiae very slender, cylindrical, the terminal spurs very un- 

 equal and rather long, the corresponding tarsi very slender and cylindrical, 

 the first joint just visibly longer than the remainder. Length 1.2 mm.

Remarkably distinct in its intense black color and feeble punc- 

 tures. The eyes are, as usual, very coarsely faceted, the facets, 

 however, unusually convex, especially beneath. The nietasternal 

 process is wide and long, extending slightly beyond the coxae, the 

 apex feebly arcuate, the sides parallel, very finely beaded and not 

 at all incurvate ; the mesosternum forms a very thick and even 

 apical bead. In crucigerus and immaculatus the metasternal pro- 

 cess is narrower, the sides being distinctly, although feebly, incur- 

 vate. 



riTOCHROPUS n. gen. 



Mentnm slightly wider than long, transversely truncate at apex, the sides 

 strongly lobed just before the middle. Ligula small, narrow and rather short, 

 deeply and distinctly sinuate in the middle at apex, not at all dentate, the 

 paraglossae very small and nearly obsolete. Labial palpi moderate ; first joint 

 slightly longer than wide, distinct, but much shorter and narrower than the 

 second, the latter feebly obconical ; third not strongly compressed, but slightly 

 wider than the second, oblique, dilated toward base, attenuate toward apex, 

 as long as the two preceding combined. Maxillary palpi well developed ; 

 second and third joints obliquely truncate at apex, the latter shorter and not 

 as long as wide ; fourth slightly longer than the preceding three together, not 

 wider than the second, cylindrical in the basal half, feebly narrowed toward
