Burmeister arranges the species which he has described in the 

 following groups : 



Group 1. Eyes very large, each of them broader than the 

 space between them. Three first joints of the maxillary palpi of 

 equal length ; fourth shorter ; fifth longer but much more slender 

 than the preceding. 



A. Fore-tibiae with apical spurs; middle tibia3 longer than the 



hind tibiae, with two spurs near the base. L. albicorais. 



B. Fore-tibiae without apical spurs. Posterior tibiae with a pair 



of more slender and rather longer apical spurs but without 

 any middle spurs. L. longicornis, concolor. 



Group 2. Eyes much smaller ; each of them much less than 

 the space between them. 



A. First joint of the maxillary palpi almost as long as the second, 

 which is as long as the third. Fore-tibiae without spurs at 

 the tips. 



a. Last joint of the maxillary palpi longer than the preceding. 

 Posterior tibiae with very small spurs at the tips. L. ater, 

 niger, interruptus, punctatus, ochraceus.
