CARABIDAE. 29 



Group II. — Oodes. 



Body glabrous, usually elliptical; eighth and ninth stria? of the 

 elytra confluent, ocellate punctures very close to the margin. Ko 

 species has yet occurred in the Pacific district, although one Oodes 

 is found in the Gila valley. 



Our genera are thus related : — 



All the tarsi pubescent beneath (anterior tarsi % with four dilated joints). 



Lachnocrepis. 

 Posterior tarsi not pubescent beneath ; 



Body finely punctulate ; anterior tarsi % with four dilated joints. 



Axatkicois. 

 Body above smooth ; anterior tarsi % with three dilated joints ; 

 Antennje slender, filiform. Oodes. 



Antennae stout, compressed. Evolekes. 



The species of Oodes have been divided into two genera by 

 Chaudoir, as follows: — 



Anterior tarsi % with the first joint entirely spongy beneath. Oodes. 

 Anterior tarsi £> with the first joint spongy only at the tip. Stenops. 



But these differences seem to me to indicate only natural groups 

 of species. 



Tribe XL— BROSCINI. 



Ligula connate with the paraglossce, which are sometimes elon- 

 gated. Antennae with four glabrous basal joints. Elytra entire; 

 abdomen connected with the thorax by a cylindrical peduncle (as 

 in Scaritini) ; anterior tibia? slightly enlarged and spinous at the 

 tip. Anterior tarsi of the male are dilated in a variable number 

 of joints, clothed beneath sometimes with a dense brush of hair, 

 sometimes with squamiform papilla?; in some genera the middle 

 tarsi are also dilated in the same sex. 



Two groups may be indicated in this tribe, according as the 

 posterior angles of the thorax are distinct or not. 



Group I. — Brosci. 



Abdomen strongly pedunculated, posterior angles of thorax in- 

 distinct. 



This group is represented only by two Russian American species 

 of Miscodera, which are unknown to me. The genus has entirely
