2G2 C0LE0PTERA OF NORTH AMERICA. 



Diclidia contains one species from Texas ; Pentaria Mnls. was 

 separated by me formerly as Anthobates, but under false charac- 

 ters, so that the name should be rejected, and the more recent one 

 adopted. The species are found on each side of the continent, 

 and have the elytra ornamented with broad bands. Anaspis is 

 also found on both sides of the continent. 



Tribe II.— MORDELLINI. 



. Body cuneiform, pointed behind ; hind coxae very large ; hind 

 tibiae short, dilated, triangular ; claws cleft to the base, with the 

 upper portion pectinate ; last dorsal segment of abdomen pro- 

 longed, forming an anal style or process ; eyes large, oval, finely 

 or coarsely granulated ; antennae inserted in front of the eyes, but 

 not very near to them, sometimes serrate. 

 Our genera may be separated as follows : — 



Eyes finely granulated ; liind tibiae with a small, subapical ridge ; 



Scutellum emarginate ; eyes not reaching the occiput. Tomoxia. 



Scutelluin triangular ; eyes reaching the occiput ; 



Last joint of maxillary palpi very transverse. Glipa. 



Last joint of maxillary palpi triangular, or securiform. Mordella. 

 Eyes coarsely granulated : hind tibise and tarsi with oblique ridges on the 

 outer face ; 

 Hind tibise with one long ridge, and no subapical one. Glipodes. • 

 Hind tibia? with subapical and oblique ridges. Mordellistena. 



Sphalera Lee, founded on Mordella melsena Germ., does not 

 appear to be sufficiently distinct from genuine Mordella. Glipodes 

 is founded on Mordella sericans Mels., and is very remarkable 

 for the structure of the last joint of the maxillary palpi in the 

 male ; it is covered on the under surface with a dense brush of 

 short hair, and from the base on the outer side proceeds a long, 

 bifurcated appendage, the branches of which are as long as the 

 joint itself. 



Mordella and Mordellistena occur on both sides of the conti- 

 nent ; the other genera are thus far known only in the Atlantic 

 States. 



Fam. lviil— anthicidae. 



Mentum trapezoidal, narrower in front, supported by a 

 broad gular process; ligula large, prominent; labial palpi 

 3-jointed.
