Genus CULICELLA. Felt.

 Wash. VII., p. 49 (1905), Dyar. 



Professor E. P. Felt takes Culex dyari, Coquillett, as the type 

 of this genus. Dr. Dyar (Proc. Ent. Soc. Wash, vii., p. 49, 1905) 

 places Coquillett's Culex melanurus here also, whilst Professor- 

 Felt places it in the genus Ecculex. 



The following is Felt's definition of the genus : — 



" Petiole of anterior fork-cell of <j? wing about two-thirds its 

 length. Posterior cross-vein about its own length from mid 

 cross-vein. Lateral vein scales well defined. Petiole of anterior 

 fork-cell in $ equal or longer than its cell ; posterior cross-vein 

 less than its own length from the mid cross-vein. Terminal clasp 

 segment of male genitalia slender, slightly curved, with small 

 apical spine. Claspette a large basal lobe with prominent 

 chitinous spine. Larva with very long air tube and with a large 

 comb consisting of linear, ciliated scales." 



I have been unable to differentiate this genus.
