KEY TO INDIANA GENERA OF MYCET.-EIN-E. 



(/. Body rounded or oval, pubescent. 



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

 half the length. I. RHYMBUS. 



W). Antennae 9-jointed ; thorax with a large, finely margined basal lobe 

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

 wards. ANAMORPHUS. 

 a a. 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 impressions and lines extend- 

 ing from base half the length. III. RIIANIS. 

 dd. Thorax with black spot on center and with deep impressions, with- 

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



IV. PHYMAPIIORA. 



I. RHYMRCS Orst. 1S5S. 



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

 impressed on each si,de; labrum prominent and truncate; antennal 

 club abruptly 3-jointed and sides of thorax strongly margined. 

 They resemble the members of the genus ^< -it minis of the Coccinel- 

 lida\ but are readily distinguished by the narrow. 4-jointed tarsi. 

 Two species and one variety occur in the State 1 on old fungus-cov- 

 ered logs.

1022 (31 7G). RHYMBUS MINOR Crotch loc. cit.
