LebiidaB. 



Lebia, Lat. 



1. L. bicolor, Dej, 5. 366. 



Rufa ; elytris subsulcatis, viridi-cyaneis j geniculis nigris. 

 Long. 4^ lin., lat. 1| lin, 



2. L. bis-binotata, mihi. 



Rufo-testacea ; elytris striatis, nigris vel nigro-brunneis, mar- 

 gine reflexo, puncto humerali, et quatuor maculis dorsalibus, 

 duabus anterioribus magnis, duabus posterioribus ininoribus, 

 luteis. 



Long. 4i lin., lat. 1| lin. 



Nearly of the same form as bicolor. Rufo-testaceous ; the elytra 

 black, or very dark umber, with the reflexed margin, a humeral spot 

 connected with the margin, two large roundish spots on the ante- 

 rior portion of the disk, and two smaller roundish spots placed 

 closer together, one on each side of the suture near the apex, 

 pale testaceous. Antennse filiform, with the three basal joints 

 testaceous, the third darker at the base, the remaining joints 

 dusky and pubescent, the last joint paler at the apex. Head 

 ferruginous, longitudinally strigose in the middle ; the striga- 

 tions tending obliquely to the centre ; two faint depressions in 

 front ; clypeus smooth ; mouth rufo-testaceous ; tips of mandibles 

 darker ; eyes prominent (though not quite so much so as in 

 bicolor). Labrum moderate, broader than long, slightly rounded 

 in front. Mentum toothed*. Thorax rufous in the middle, the 

 margins pale and transparent, broadly reflexed ; mesial longitudi- 



* As is observed by Lacordaire (Genera des Coleopteres, i. 127), there 

 is considerable difference of opinion among authors, whether in the genus 

 Lebia the mentum has a middle tooth or not ; Bonelli, Chaudoir, and 

 others maintaining that it has; while Schiodte, Schmidt-Goebel, and 

 Lacordaire himself are of opinion that it has not, — viewing the piece which 

 is supposed by the former to be a tooth, as a semi-corneous plate which 

 forms the central base of the ligula, and, in dissecting the head, is often 

 taken off attached to the mentum, but is separable from it. That it is so 

 in some instances, there is no doubt; as, for instance, in Lebia crux minor. 

 In other cases there is no appearance of a tooth at all, either as forming 

 part of the mentum or the base of the ligula. Lebia scapularis, and other
