Southern States. The subapical tooth of the intermediate tibiae of the male is very 

 obtuse ; the apical process large. 



3. L. strenuus, depressus, nitidus, elytris tripunctatis, profundius striatis, interstitiis convoxis, pectore 



toto Isevi. Long. -7. 

 This species is exactly similar to the preceding, except that the thorax is less nar- 

 rowed behind, and that the pectus is entirely smooth ; there are traces of a few punc- 

 tures upon the presternum. For a single male specimen, found at New York, 1 am 

 indebted to my friend J. C. Brevoort ; the tooth of the intermediate tibiae is sharp ; 

 the apical process not visible. 



4. L. scrutator, pernitidus, depressus, elytris tripunctatis, striis externis subobsoletis, interstitiis 



subconvexis, pectore parce punctulato. Long. -6. 



Lypcrus scrutator Lee. An. Lye. 4, 342. 



Cleveland, Ohio. The locality given in my former description is incorrect. This 

 species again is almost exactly like the preceding, but the posterior angles of the 

 thorax are a little less prominent; the striae of the elytra are less deep, and become 

 fainter towards the apex, the seventh stria is almost obliterated. The subapical 

 tooth on the inner surface of the intermediate tibiae of the male is long and sharp, and 

 the apical process is not distinct. 



HOLCIOPHORUS Lee. 



Antennae crassiusculae, basi non carinatas ; palpi cylindrici, articulo ultimo breviore ; mentum dente medio 

 concave et emarginato, ligula carinata apice late angulatim emarginata, paraglossis liaearibus paulo longiori- 

 bus ; labrum emarginatum; parapleuree breves; abdomen articulo 1'"° impresso ; elytra punctis dorsalibus 

 nullis, sed stria scutcllari notata ; tarsi posteriorcs extus non sulcati ; antici maris articulis 3 dilatatis, 

 obcordatis, profunde emarginatis ; tibiae postcriores maris intus obtuse serrulatae. 



This genus is founded on a very fine species from California, also with carinate 

 ligula, and without any tarsal grooves ; but differing from the preceding b}'- its 

 thicker antennae, short epipleurae and the absence of dorsal punctures. 



The head is large, the thorax flat trapezoidal, emarginate anteriorly, much 

 narrowed behind, moderately margined on the sides, margin reflexed, not wider 

 behind, posterior angles rectangular, basal impressions deep, with two slight striae ; 

 elytra not wider than the thorax, flattened, dorsal punctures none ; scutellar stria 

 distinct, between the first and second striae ; margin a little broader than usual ; 

 marginal stria not equidistant between the punctures and margin ; tarsi thick, fourth
