7 Body black, slightly shining; prothorax with the sides strongly rounded 

 and subreflexed, densely, variolately punctate, less retuse medially 

 at base than in incequalis; elytra uneven in sculpture, smooth toward 

 the suture and apex. Length 15.7 mm. Southern California

8 General form as in in (equal is but more slender and elongate, piceous- 

 black, shining, with but few punctures or irregularities above; 

 head coarsely, sparsely punctate, subopaque; prothorax about a 

 third wider than long, the sides strongly arcuate; base narrower 

 than at middle, the surface convex, with a basal depression opposite 

 the scutellum, very shining and sparsely punctate, becoming opaque 

 and a little more punctate laterally; elytra smooth, very sparsely- 

 punctate, the surface with vague traces of sulci; epipleura well de- 

 nned; prosternum between the coxje rather wide, obtuse at tip, 

 coarsely granulate; propleura opaque and sparsely punctate; met- 

 episterna fully one-half longer than wide; abdomen shining, sparsely 

 punctate; legs muricate. Length 15.0 mm. Arizona [Microschatia

The last species of the table is included with some doubt, as it 

 manifestly differs very much from the incequalis type and belongs 

 to a somewhat different faunal region. However, it evidently 

 fits the present genus better than Microschatia and may be safely 

 left here until its generic characters can be observed more fully. 

 The form made known, in very few words by LeConte tinder the 

 name Microschatia puncticollis, would appear to be specifically 

 distinct from inceqitalis and its immediate allies, in having the 

 pronotum punctured rather than muricate; this feature was evi- 

 dently overlooked in reducing it to synonymy.

While resembling Pycnonotida in many of its more important 

 characters, such as the thick antennee with obliquely emarginate 

 tenth joint, stout tarsi with the intermediate joints of the anterior 

 very short and subperfoliate, median impression at the base of the 

 pronotum, reproduced however in Euschides and some other genera, 

 and narrow inflexed sides of the elytra although in the typical 

 species the epipleura are not defined it would seem that punctata 

 and championi must form a separate genus, because of the different 

 form of the body, radically different sculpture in having the elytra
