(^OXKLiUS Latr. 

 C. serratus n. sp. — Oblon^r oval, brown or piceous, opaque. Head granular, 

 with sparsely placed scale-like hairs. Antennae with joints 2-8 short, the outer 

 ones moniliform, the third not longer than fourth. Thorax transverse, slightly 

 narrower behind, disc convex, a vague median groove, margin narrowly serrate 

 and fimbriate, surface granular and punctate. Elytra oval, not, wider than the 

 thorax and about two and a half times as long, with rows of very large and deep, 

 closely placed punctures, the intervals very narrow, surface sparsely clothed with 

 short cinereous pubescence. Body beneath granulate, opaque. Length .0<S-.]0 

 inch; 2-2.5 mm. 



A very small species compared with our others, and with dispropor- 

 tionately deep elytral sculpture. When the surface is coated with the 

 usual exudation it seems roughly granulate. Easily known by its small 

 size and serrate thorax. 



Two specimens from California, from Mr. H. Ulke.

Head deeply inserted, front deeply concave with two feeble carinse convergent 

 above, epistoma truncate. Labrum small, trapezoidal. Mandibles stout, not

Thorax transverse, antennal fossa large and deep, situated at the anterior angle 

 of the thorax between the dorsal and pectoral plates, widely open in front. Pros-

 slightly excavated at middle.
