Genus CCCCLXXXIII.— Bythinus, Leach. 



Antennce rather short, the basal joint cylindric, the second in the males very 

 large and produced within, the six following much smallei-, equal, lenti- 

 cular, ninth and tenth broader, also lenticular, eleventh much larger, with 

 the apex very acvite. Palpi very long, the basal joint slender, with the 

 apex gradually clavate, second small, ovate, third very large, flat, hatchet- 

 shaped, or elongate : head broad : thorax narrowed behind : elytra covering 

 above half the abdomen, the latter with the exposed segments subequal ; 

 femora moderately incrassate ; tibiae and tarsi slender. 



The singular genus Bythinus may be known by the magnitude of 

 the second joint of the antennae, which last is remarkably produced 

 within in the males ; the bulk and length of the maxillary palpi, as 

 well as the size and form of their terminal joint, are also very 

 important characters of distinction.
