AMERICAN COLEOPTERA. 313 



LUDIUS, I.atr. 

 L. Lecontei, n. sp. — Elongate, black, suh-opaquc, very sparsely clothed with 

 greyisli hairs. Head and thorax coarsely and densely punctured. Thorax 

 longer than broad, sides rounded in front, parallel at posterior two-thirds, hind 

 angles divergent and acutely carinate. Elytra as broad as thorax at base, sides 

 nearly straiglit and gradually narrowed to apex; apex feebly sinuate and with 

 the suture slightly prolonged: surface with fine punctures arranged in strire, 

 the intervals finely and distantly biseriately punctured. Body beneath sparsely 

 punctulate. Length .72— .96 inch ; 18— 24 mm. PI. IV, fig. 13. 



The antenna) have the last joint with a false piece at tip as in all 

 our other species, llesembles L. a^;y, Cand., differs in the thorax be- 

 ing less narrowed in front, less convex and with the hind angles more 

 strongly divergent and more acutely carinate. The elytra are also dif- 

 ferently sculptured there being striae of moderately fine punctures 

 rather distantly placed, the intervals being marked with still finer 

 punctures biseriately arranged but more distantly placed than the 

 larger punctures. The elytral apex ( S ) is distinctly sinuate and the 

 suture prolonged as in OrtliDstctlma iiifuscatus Germ. In L. atrr, 

 Cand., the elytra are densely punctulate without any strial arrange- 

 ment and the apex obtuse. The hind coxal plates at the free edge of 

 the dilated portion are more strongly angulate. 



In general aspect the present species is much more slender than any 

 of our LiKfii, and much less convex than L. atcr, to which it is most 

 closel}' allied. 



The males and females differ in a less marked degree, the form of 

 thorax scarcely varying. 



Specimens are known to me from Santa Barbara, Tejon and San 

 Diego, California. 



LIMONIUS, Esch. 

 L. quadrimaculatus, n. sp. — Black, shining, sparsely clothed with greyish 

 hairs. Head flattened frontal margin feeble, surface denseh' punctured. An- 

 tennae, especially in the male strongly serrate beyond the third joint ; joints 2 — 

 3 small, rounded, scarcely equalling together the fourth. Thorax one-fourth 

 longer than broad at base, gradually narrower in front, sides feebly rounded ; 

 apex feebly einarginate angles not prominent, hind angles acute not diverging 

 beyond the line of the sides, and with an acute carina extending slightly more 

 in length than jthat of the angle; disc of thorax [moderately convex rather 

 densely punctured. Elytra as broad us thorax at base feebly narrower toward 

 apex, sides very feebly rou^ided, moderately convex, surface finely striate, 

 striaj punctured intervals moderately convex and scabrous ; color black shin- 

 ing with bright humeral s])ot extending on the epipleuraj and one-third the 

 length of the elytra, not attaining the suture, another transverse spot at the 

 apical fourth attaining neither the suture nor margin. Body beneath black 

 shining, sparsely pun«tured and clothed with greyish hairs. Legs black. Tarsi 

 with the first joint of anterior and middle nearly equal to the two following ;
