(Orthops, Fieb.) 
This rather extensive genus consists of a number of 
species of very similar general facies, the most aberrant 
of our species being L. pabulinus, belonging to a little 
section of three species, of which it is our only repre- 
sentative; these differ from the others by the incom- 
plete carina at the back of the head, which is only visible 
near each eye; the old subgenus Orthops is only dis- 
tinguishable by the shorter antenna. 
Oval or elongate oval. Head with the face subvertical, 
vertex carinated entirely or in part; rostrum reaching to 
about the third pair of coxee; pronotum convex, with a 
narrowly raised collar, base much raised; elytra with the 
sides more or Jess rounded ; tibiz with fine, sometimes black 
spimes, second joint of tarsi slightly longer than the 
first. 
(10) 1. Green, antennew very long and slender, 
legs green.
