I have seen the type specimen of Jlorio piceus, Casteln., in the 

 Howitt Collection. It had the scrobe of the mandibles setioero- 

 punctate, and on comparing it with the species I identify as 

 Melisodera picipennis, Westw., I found them to be the same. 



Genus M o r i o d e m a. 



Count de Castelnau in diagnosing his genus Moriodema said 

 the mentum is "without any appearance of a tooth"; this is 

 inaccurate, for, although the inner margin of the epilobes forms 

 a well developed ridge 'across the bottom of the sinus, giving it 

 the appearance of being edentate if not carefully examined, there 

 is a short wide prominence or tooth in front of this ridge. 

 Moriodema is closely allied to Melisodera, but it is a form that will 

 certainly receive at least subgeneric rank from those who use sub- 

 genera, so it seems better not to merge it with Melisodera, from 

 which it differs, as far as I can see from the specimens before me, 

 by mentum with sinus shallower, the basal border not advanced 

 in the middle; maxillary palpi with penultimate joint much longer 

 (about as long as apical); orbits obliquely narrowed behind eyes; 

 prothorax differently shaped and without a short submarginal 

 ridge near basal angles; anterior tibia3 arcuate on outer side.
