108 NORTHERN ZOOLOGY. 



Family CHOLEVID^. Cholevidans. 



LV. Genus CHOLEVA. Lat. Sp. 

 ix. * Subgenus Catops. Steph. 



(154) 1. * Choleva (Catops) Spenciana. Spencian C. Catops. 



C. C. (Spenciana) nigra, pallido pubescens ; prothorace angulis rotundatis, postice subrepando ,■ antennis basi, pedibusque 



ferrugineis; eli/tris ferrugineis apice nigris. 

 Spencian C. Catops, black with pallid pubescence ; prothorax with rounded angles, posteriorly rather wavy ; legs, and base 

 of the antennae, ferruginous ; elytra ferruginous, black at the tip. 



Length of the body 2 lines. 



A single specimen taken. Locality not stated. 



DESCRIPTION. 



Body black, covered with decumbent pale hairs. Head minutely punctured; antenna? shorter 

 than the prothorax, the two first joints ferruginous, the eighth shorter and smaller than the rest ; 

 mouth and palpi ferruginous ; prothorax not visibly punctured with all the angles rounded ; 

 base with a slight sinus on each side: elytra acute, very minutely punctured with a hair emerging 

 from each puncture, without furrows except a single one parallel with the suture, ferruginous, black 

 at the tip : abdomen piceous, rufous at the base : legs ferruginous. 



This species appears to present the type of a new family of Choleva, not noticed in Mr. Spen- 

 cer's Synopsis Sectionum, in his admirable Monograph of that genus. 4 From his first section 

 (Choleva Steph.) it borrows the rounded posterior angles of the prothorax; from his second (Catops 

 Steph.) its clavated antenna?; and from his third (Ptomaphagus Steph.) its unfurrowed elytra: it 

 seems properly included in the second, with which it most agrees in habit. 



Family SCAPHIDIAD^. Scaphidiadans. 



LVI. * Genus SCAPHIUM. Kirb. 



Labrum transverse, submembranous, subemarginate. 



Labium subquadrangular, corneous. 



Tongue membranous ? 



Maxillary Palpi four-jointed : first joint very short ; second rather longer than the rest, nearly 



cylindrical ; third obconical ; last conical, acute. 

 Labial Palpi three-jointed : joints nearly cylindrical ?
