MORDELLIDAE. 261 



prothorax "by a very small neck ; eyes small and coarsely 

 granulated in the first tribe, large and finely granulated in 

 the second ; labrum prominent ; mandibles short, entire at 

 tip, with an internal membranous margin. 



Antennas inserted at the sides of the front, before the eyes, 

 11-jointed, slender, usually slightly thickened externally. 



Prothorax strongly narrowed in front, as wide at base as 

 the elytra ; lateral suture quite obvious ; coxal cavities large, 

 open behind, confluent. 



Mesosternum short, carinated, pointed behind, side pieces 

 attaining the coxal cavities, which are not confluent ; meta- 

 sternum large, but not long, side pieces variable in width. 



Elytra narrowed behind, not truncate, leaving exposed the 

 tip of the abdomen ; epipleuras not distinct. 



Abdomen with five or six ventral segments; the last 

 dorsal and sixth ventral are prolonged in the second tribe, 

 forming an anal style. 



Legs, anterior short, posterior usually long ; anterior coxae 

 large, conical, contiguous, without trochantin; middle coxae 

 not prominent, slightly separated; hind coxae flat, contiguous, 

 moderate in size in the first, very large in the second tribe ; 

 tibial spurs large, hind tibiae frequently dilated ; hind tarsi 

 compressed, long ; claws simple in the first, cleft to the base, 

 with the upper portion pectinate, in the second tribe. 



Two tribes are thus separated : — 



Abdomen riot prolonged at tip. Anaspini. 



Abdomen prolonged at tip. Mohdelliki. 



Insects of small size, found on plants ; all are pubescent ; many 

 are very prettily variegated in color. 



Tribe I.— ANASPICT. 



Body rather fusiform than cuneate ; hind coxa? not very large, 

 tibia? slender ; claws neither cleft nor serrate ; last dorsal seg- 

 ment of the abdomen not prolonged, sixth ventral not visible in 

 Anaspis, but visible in the other two genera ; eyes oval, narrowly 

 emarginated, coarsely granulated ; antennas inserted very near the 

 eyes, not serrate ; upper surface of the body transversely strigate. 



Our genera are three : — 



Anterior and middle tarsi with the 3d and 4th joints equal; 



Antennae long, scarcely thickened externally. Diclidia. 



Antenna? shorter, last five joints broader. Pentauia. 



Anterior and middle tarsi with the 4th joint very smalh Anaspis.
