96 INSECUTOR INSCITI^ MENSTRUUS 



8. Culcx (Culex) corniger Theobald. 



Culex corniger Howard, Dyar and Knab, Monog., iii, 240, 1915. 



The genus Trichopronomyia Theobald is available for this 

 species, but, although it is unique, I do not think the distinctions 

 are strong enough for a subgeneric separation. 



9. Culex (Culex) tarsalis Coquillett. 



Culex tarsalis Howard, Dyar and Knab, Monog., iii, 230, 1915. 



10. Culex (Culex) stigmatosoma Dyar. 



Culex stigmatosoma Howard, Dyar and Knab, Monog., iii, 236, 

 1915. 



11. Culex (Culex) eumimetes Dyar and Knab. 



Culex eumimetes Howard, Dyar and Knab, Monog., iii, 238, 1915. 



The genitalia agree with tarsalis while the adult is colored 

 like stigmatosoma, though there is nothing very decisive about 

 this as the difference between tarsalis and stigmatosoma is 

 slight, consisting only in the difference in the number of teeth 

 on the second uncal plate, which varies. Probably eumimetes 

 is the same as stigmatosoma; the larval differences on which 

 the species was founded and which we repeat in the mono- 

 graph with distinctly less emphasis do not exist. 



It will be noted that duplicator, which falls here on color- 

 ation, is entirely unrelated on genitalic characters, thus con- 

 firming the value of the different wing-scaling. 



12. Culex (Culex) erythrothorax Dyar. 



Culex erythrothorax Howard. Dyar and Knab, Monog., iii, 315, 

 1915. 



13. Culex (Culex) salinarius Coquillett. 



Culex salinarius Howard, Dyar and Knab, Monog., iii, 373, 1915. 



14. Culex (Culex) janitor Theobald. 



Culcx janitor Howard, Dyar and Knab, Monog., iii, 25S, 1915. 



The larvae differ from allied species in having the antennae 

 without the "notch," agreeing in this with restuans.
