CULEX DYAEI 457 



In completion of the observations of Prof. Smith that the larvae occur from 

 late autumn to early spring, are those of Dr. Dyar and Mr. Knab. Dr. Dyar, in 

 New Hampshire, found larvae in various stages in July, from which adults were 

 bred in August, and, in New York, he found larvae in August. Mr. Knab, in 

 Massachusetts, found a full-grown larva in August. 



Eastern United States. 



Center Harbor, New Hampshire, August 19, 1902 (H. G. Dyar) ; Tupper 

 Lake, New York, larvae August 11, 1905 (H. Gr. Dyar) ; Westfield, Massa- 

 chusetts, larvae August, 1903 (F. Knab) ; Lahaway, New Jersey, larvae March 

 37 (J. T. Brakeley) ; Alexandria, Virginia, September 23, 1899 (F. C. Pratt) ; 

 Lake Drummond, Virginia, October 29, 1906 (H. S. Barber) ; Augusta, 

 Georgia, August 10, 1909 (W. V. Eeed). 



Dr. Peryassu has placed this species as a synonym to Neomelanoconion in- 

 decorabile, but evidently without examining specimens. We do not think there 

 is any chance that this synonymy is correct, as we have never had Culex melan- 

 urus from without the limits of the United States. Besides, Theobald's descrip- 

 tion of Culex indecorahilis does not agree with specimens of Culex melanurus 

 (see Mon. Culicid., iii, 341, 1903). 



Subgenus CULICELLA Felt. 



The genus CuliceIJa was founded by Felt on the characters of the male 

 genitalia of Culex dyari; but no other distinguishing characters were indi- 

 cated (Bull. 79, N. Y. State Mus., 391c, 1904). Coquillett defined the genus 

 by the bare stripes of the mesonotum (U. S. Dept. Agr., Bur. Ent., Tech. Ser. 

 11, 16, 1906) ; such stripes, however, are developed in various degrees in most 

 species of Culex. The larva is of the Culex type, but differs in the presence of 

 a series of hair-tufts ventrally on the anal segment, in front of the ventral brush 

 and inserted in a series of perforations of the chitinous ring, as well as in the 

 basally situated tuft of the air-tube. The male genitalia and the habits exhibit 

 a generalized type. However, we are unable to point out good structural char- 

 acters for separating both sexes of the adults from Culex, and so reluctantly 

 treat the group as a subgenus only. 



Eecent work by J. C. H. de Meijere and F. "W. Edwards proves that there 

 exist in the old world at least two species of this generic type, intermediate 

 between Culiseta and Aedes, and connecting them by larval characters. The 

 species {fumipennis Stephens and morsitans Theobald) are classified by de 

 Meijere in Culicada {Aedes) and by Edwards in Theohaldia ( = Culiseta) ; 

 in fact they lie between the two. C. dyari is the only representative of this type 

 in America. We believe that the genus Culicella will ultimately prove valid. 

 These species are entirely out of place in Culex, lying, as we have said, between 

 Culiseta and Aedes.
