71 THE SHORTER SCIENTIFIC PAPERS 



Elytra short, oval, decidedly broader than the pro- 

 thorax, attaining their greatest width about one-fifth of 

 their length from the base; punctures arranged in more 

 or less confused rows; subsutural striae broadly curved at 

 the scutellum and attaining the middle of the base of the 

 elytra; composed of extremely large punctures which 

 reach their maximum size near the scutellum. 



Length 1.9 mm. 



Distribution. — Gambier, Ohio, (U. S. A.). 



The species is easily distinguished from its nearest ally 

 S. gibberosiis Lucas, of Europe, and from other undescrib- 

 ed North American species, through the comparatively 

 much broader elytra and the extremely large punctures 

 near the scutellum in the subsutural striae. Furthermore 

 it is darker in color, and there is a difference in the ar- 

 rangement of the ordinary elytral striae. 



One of the specimens was partially dissected which 

 afforded an opportunity of observing the contents of the 

 digestive tract. This was found to contain a mass of 

 minute spores each somewhat oval in form and 10 mic. 

 in length. The entire tract from the mid portion of the 

 metathorax was filled with the spores, and by counting 

 the number in a given area, an approximation of the total 

 gave 13,500 for the number in the tract. Unfortunately 

 the fungus with which the species was in association was 

 not collected, so even the family to which it belonged 

 cannot be noted with certainty. 



It seems certain that Symbiotes will be found widely 

 distributed in North America.
