conspicuous dilated scales. Terminal clasp segment of male geni- 

 talia slightly swollen. Claspette a conspicuous basal lobe bearing 

 a stout, apical spine. Harpes strongly curved and bearing a 

 series of stout teeth. Species, per turbans Walk. 



Stegomyia. We have had no oppprtunity of studying either 

 larvae or adults of S. s i g n i f e r Coq., the only species liable to 

 occur in New York State. Judging from descriptions and a print 

 of the male genitalia kindly sent us by Dr Dyar, it probably be- 

 longs close to TaenioThynchus; 



Culex. Petioles of fork cells of female wing short, that of the 

 anterior one seventh to about one fifth the length of its cell. Pos- 

 terior cross vein more than its own length from mid cross vein, 

 lateral scales linear, well defined; vein scales broadly rounded, 

 closely appressed. Petiole of anterior fork cell in male about one 

 third its length. Lateral scales well marked but more sparse than 

 in the other sex. Claspette represented by a prominent tuft of 

 chitinons spines and frequently by a dilated, spatulate organ at 

 the apical third and a rather inconspicuous prominence near the 

 base of the clasp. Larvae with very long air tube bearing incon- 

 spicuous basal pecten, and with comb composed of about 50 

 minute, ciliated scales. Type, p i p i e n s Linn., species, s a 1 i - 

 n a r i u s Coq., restuans Theo, and territans Walk. 



Protoculex n. gen. Petiole of anterior fork cell of female wing 

 about one half the length of the cell. Posterior cross vein more 

 than its own length from mid cross vein. The long lateral scales 

 well separated from the appressed vein scales. Petiole of anterior 

 fork cell of the male about equal in length to that of the cell. 

 Terminal clasp segment of male genitalia slender, curved, with 

 sitout apical spine. Claspette represented by a conspicuous basal 

 spine-bearing lobe and a longer terminal one. Harpes broadly 

 dilated at base, slender apically; harpagones with recurved apical 

 spine. Larva with medium air tube, comb consisting of a few 

 spinelike scales. Type, serratus Theo. 



TJranotaenia. Petiole of anterior fork cell of female wing ex- 

 ceedingly long. Posterior cross vein scarcely its length from mid 

 cross vein. Wings remarkable on account of the varied character 

 of the scales. Terminal clasp seg<jienit of male genitalia straight.
