THE HANDSOME FUNGLTS BEETLES. 535 



KEY TO INDIANA GENERA OF MYCET^IN^. 



a. Body rounded or oval, pubescent. 



6. Antennae 10-jointed; thorax with well marked basal lines, extending 

 half the length. I. Rhymbus. 



66. Antennfe 9-jointed; thorax with a large, finely margined basal lobe 

 and a basal line each side running forward and then curving in- 

 wards. Anamoephi's. 

 aa. Body oblong or elongate. 



c. Pubescent ; base of thorax not, or very feebly, narrower than middle, 

 but slightly narrower than base of elytra. II. Symbiotes. 



cc. Glabrous ; base of thorax distinctly narrowed, that of elytra very evi- 

 dently the wider. 

 '/. Thorax unspotted, with deep basal imiiressions and lines extend- 

 ing from base half the length. III. 1{iianis. 

 dA. Thorax with bla<'k spot on center and with deep impressions, with- 

 out lines; antennal club of male very large. (Fig. 4. No. 8.) 



IV. Phymapuoka. 



I. Rhymbus Gerst. iSfiS. 



Very small, convex, pubescent species, having the thorax deeply 

 impressed on each side; labrum prominent and truncate; antennal 

 club abruptly :3-jointed and sides of thora.x; strongly margined. 

 They resemble the members of the genus Scj/nuuts of the Coccinel- 

 lidag, but are readily distinguished by the narrow, 4-,iointed tarsi. 

 Two species and one variety occur in the State on old fungus-cov- 

 ered logs.

 tra dark reddish-brown, the margins and suture narrowly paler ; antennal
