larly difficult species for a tabulation, because in two respects 

 it is near the border land between aggregates. Its hind claws 

 are not of the conspicuously bifid type, the hinder of their 

 two projections being much smaller than the apical ; the 

 hinder projection, however, is decidedly more denned than 

 that in any species whose claws I have called appendiculate, 

 and is wide, with its apex truncate, the middle and front 

 claws being, moreover, quite unmistakably of the bifid type. 

 The prothorax of this species is very little less than twice as 

 wide as long ; by measurement it is actually less than twice, 

 and when placed beside a species in which the prothorax is 

 fully twice as wide as long it is quite apparent that the pro- 

 thorax is less transverse. It will, however, be well to note 

 that if the species were to be mistaken for one with the wider 

 prothorax its place would be regarded as near viduus and 

 pauxillus, to neither of which it bears much general resem- 

 blance, differing from the former, inter alia, by its coarsely- 

 punctured frons nearly continuous in plane with the clypeus, 

 and from the latter by its very much larger size, etc. It is 

 easily separable from incola by the clypeal character indicated 

 in the tabulation, and in addition the puncturation of its 

 elytra is quite evidently finer, and the basal joint of its hind 

 tarsi is quite evidently longer in proportion to the 2nd joint. 

 The trilobed outline of its head is fairly well defined, but not 

 quite divided, the middle lobe about two-thirds of a lateral 

 lobe in size. The front of the pronotum bears a fringe of 

 erect hairs, as in incola.
