Coleopterological Notices, V. 291 



from the fourth, forming a long compact cylindrical club, have the 

 metasternal process between the middle coxae long and acute, while 

 the others, with slender or feebly incrassate antennae, have this pro- 

 cess either entirely obsolete, or else in the form of an extremely 

 short broad cusp. The former may or may not be congeneric with 

 the European Mycetodrepa, of which I do not possess a represen- 

 tative at present, but in any event the three here brought to notice 

 differ greatly among themselves in somewhat important characters. 

 The genus will prove to be very extensive in North America, and 

 I have simply selected at the present time a number of hitherto 

 undescribed forms, for the most part illustrative of groups; these 

 may be known among themselves as follows : — 



Antennse more slender, gradually and generally feebly incrassate toward tip. 



Third antennal joint distinctly longer than the second, the antennae long ; 



abdomen parallel, narrowed slightly at the fifth segment ; prothorax 



widest before the bas'e, the basal angles almost completely obliterated ; 



basal joint of the hind tarsi as long as the next three COngriienS 



Third antennal joint equal in length to the second, both elongate ; antennse 



much shorter ; elytra distinctly longer than the prothorax. 



Prothorax widest before the base ; abdomen narrowed from base to apex ; 



basal joint of the hind tarsi as long as the next three. ..convergens 



Prothorax widest at base ; abdomen parallel, narrowed near the tip ; basal 



joint of the hind tarsi but slightly longer than the next two. 



impressa 

 Third antennal joint distinctly shorter than the second.. 

 Elytra longer than the prothorax. 



Elytra pale, clouded with black toward the scutellum and toward each 



flank ; abdominal punctures not so dense nilbifer 



Elytra uniform in coloration or very nearly so ; sides of the elytra per- 

 fectly parallel; integuments subopaque saxatilis 



Elytra shorter than the prothorax. 



Prothorax subconical, widest at or near the base, where it is a little 

 wider than the elytra. 

 Abdomen blackish, the apices of the segments narrowly paler. 



glenorae 

 Abdomen rufous, with a large blackish cloud occupying most of ter- 



gites three to five ; form very slender ; size small nigriceps 



Prothorax with the sides perfectly parallel and broadly, evenly arcuate 

 from base to apex, not wider than the elytra ; body very small and 



narrow, piceous and black in color lilieata 



Antennse rapidly enlarged from and including the fourth joint, forming a long, 



compact, claviform mass. 



Antennae, except near the base, completely devoid of erect setae, clothed 



uniformly with excessively minute even pubescence, almost perfectly 



cylindrical from the fifth joint blldsouica
