TKEDACEOUS GROUND-BEETLES. 



J.l 



win^'-covers, and all the other parts reddish yellow ; and several similar 

 smaller species, which seem to pass insensibly into each other, are olteu 

 found in colonies under stones in dry places. Lehia contains many 

 prettily colored species, mostly a quarter of an inch or less in len<ith. 

 Jjfbia (jr(()i(Us, Ilentz (Fi^". 11), upwards of a third of an inch long, colored 

 much like a Brachinus, is our largest species. This is one of the i)re- 

 dacious insects wliich h^ve been seen to devour the larv;e of the (Colo- 

 rado i)Otato-beetle. The species of J>ebia are sometimes found on low 

 or herbaceous plants, and sometimes running up the trunks of trees in 

 search for their minute insect prey. 



The genera Dromlns^ meaning a noino', and Calleida, meaning hcdu- 

 tiftd, have similar habits. Cymindis is found under stones. Cmnonia 

 jH'iuisylranica, an elegant little insect, quarter of an inch long, and re- 

 markable for its slender spindle-shni)ed thorax, is usually seen running 

 upon the ground. The head and thorax are black, and the elytra red, 

 with two black bands. It is not a very rare species. 



Liptotrachclus also, as its nauu' implies, lias a slender thorax, of about 

 the same width throughout. This genus is usually classed in this sub- 

 family, or near it, but it is exceptional in having the elytra entire and 

 completely covering the abdomen. 



Uelluomorpha, of which we have several species, and the allied genus 

 MorlOy of which we have but one Southern species, differ from all our 

 other Carabideous insects, in having the antennic stout and almost 

 bead-like, and either enlarged or strongly comi)ressed toward the tip. 



Subfamily CHL^^NIIDES. 



The distinctive character of the Chla?niides consists in the structure 

 of the anterior tarsi of the males, which have the three first joints 

 widened, and furnished beneath with crowded points, or hair like papillte 

 [Fig. 12 1 iill of the same length so as to 



resemble a brush. These 

 Joints are usually more or less 

 rounded at the corners, bear- 

 ing a fanciful resemblance to 

 the patella or Kiwcpan, which 

 suggested to Latreille the 

 name Pntellunnni^ by which 

 he designated this sub-family; 

 mani^ meaning hands, a texm
