616 Coleopterological Notices, IV. 



epimera slightly visible from above. Scutellum sparsely clothed 

 with dark-brown squamules. Pygidium completely covered, the 

 fifth ventral segment not as long as the two preceding together. 

 Met-episterna narrow. Tarsi normal, the claw T s moderate, free and 

 divergent. In some of these characters the genus is related to 

 Nicentrus, but the strongly tubulate prothorax and rhomboidal 

 form of the body will readily distinguish them. 



1 Ceiltrinites Strigicollis n. sp. — Rhomboid-oval, moderately stout, 

 convex, shining, black, the tibiae, tarsi and antennae more or less piceous ; 

 vestiture consisting of elongate slender white scales and slightly smaller pice- 

 ous squamules, the former broadly along the sides and on the basal lobe of 

 the pronotum, and also on elytral intervals two, near the base and toward 

 apex, four and six broadly, and three, five and seven in single sparse lines 

 which are less distinct toward base and apex ; under surface rather sparsely 

 clothed with white scales, the met-episterna very densely so throughout. 

 Head finely but strongly, rather closely punctured, the transverse impression 

 broadly angulate but distinct ; beak somewhat stout but not much thicker 

 toward base, evenly, distinctly arcuate, fully as long as the head and pro- 

 thorax, the flattened sides deeply densely and rugosely punctate, the dorsal 

 surface polished and with an even series of small punctures at each side of 

 the impunctate line ; antennae inserted a little beyond the middle, the scape 

 extending three-fourths the distance thence to the eye, the basal joint of 

 the funicle fully as long as the next three, the second less than one-half 

 as long as the first and one-half longer than the third, outer joints finely 

 pubescent, and also coarsely setose, club finely, densely pubescent, moderate 

 in size, the basal joint forming nearly one-half the mass. Prothorax two- 

 thirds wider than loug, the sides feebly convergent and nearly straight to 

 apical third, then strongly rounded to the well-marked constriction ; apex 

 tubulate and fully one-half as wide as the base, the latter transverse, sin- 

 uate at each side of the small moderately distinct median lobe ; disk 

 with long deep longitudinal rugae, the median line very finely carinate. 

 Scutellum quadrate, emarginate behind, sparsely clothed with brown squa- 

 mules. Elytra, distinctly wider than the prothorax and more than twice as 

 long, the humeri rather prominent but obtuse ; sides strongly convergent, the 

 apex somewhat narrowly rounded ; disk moderately and not very abruptly 

 striate, the intervals flat, about twice as wide as the grooves, the first, third, 

 fifth and seventh uniseriately punctate, the others confusedly so, the punctures 

 moderate, deep, not very dense. Prosternum with a deep squamose parallel- 

 sided longitudinal impression, ending behind the anterior margin in a small 

 transverse nude and deeper pit, the coxae separated by one-fourth of their own 

 width. Length 3.5 mm. ; width 1.7 mm.

This species bears a deceptive resemblance to Centrinus tortuosits, 

 but is less robust and has the pale scales arranged in rows and not
