Genus Culicada. 359 



the cell ; posterior cross-vein not quite its own length distant 

 from the mid. Fore and mid ungues unequal, the larger bi- the 

 small uniserrated ; hind equal and uniserrate. 



Genitalia with basal lobe of clasper* very broad and ending 

 in a broad truncated apex from which the small clasper arises at 

 the outer corner ; central processes broad and terminating in a 

 beak -like extremity. 



Length. — 6 mm. 



Habitat. — Karner and Elizabeth Town, New York (E. P. Felt). 



Time of appearance. — May. 



Observations. — Redescribed from a series sent me by Professor 

 Felt. It is a very distinct Culicada, the thoracic adornment is 

 different to any I have seen with unhanded legs. 



The male genitalia are also peculiar. Dyar has described the 

 early stages (N. Y. Ent. Soc. Journ. XII, 169-171 (1904) ).

 hairy in places, especially on the inner side ; between the basal
