This species inhabits the Mississippi Valley region — Illinois, 

 Arkansas, Louisiana, and Texas. The larva has a straight, 

 rather long- air-tube, body and tube minutely pilose; lateral 

 comb of the eighth segment in an irregularly double row. They 

 live in permanent bodies of water full of aquatic vegetation. 

 The genitalia have the side pieces greatly swollen, the lobes 

 divided and highly modified ; the clasp filament is distorted, 

 furnished on the outer margin with fine hair and a nearly 

 solid crest ; terminal spine strong and curved like a hook.

 habits are unknown. The male genitalia are as in erraticus 

 but the clasp filament has a weak terminal spine, the crest fea- 

 thered, not solid.
