Culex restvans is closely allied to C. pipiens and to C. salinarius, with both 

 of which it occurs mixed in artificial receptacles holding water. Mr. S. E. 

 Weber is of the opinion that these three species are mutants of one species, and 

 has published what he considers evidence in support of his conclusion. We are 

 unable to concur in this opinion, as we find the three species constantly different 

 in all stages, and consequently do not adopt Mr. Weber's view. As these species 

 show closely similar coloration in the adult, and commonly occur mixed in 

 breeding-places near houses, most of the references to the " house mosquito " 

 refer to the three together, and not to any one species. Most of the accounts 

 of " Culex pungens " refer at least in part to the present species. In northern 

 localities, or in small places distant from larger centers, Culex restuans is 

 often the only species breeding in rain-barrels; in places where such barrels 

 are situated in woods it may be associated with C. territans. In certain locations 

 the larv?e have been found with very long gills, the reason for which is not 

 known. It is, however, a phenomenon to be seen occasionally in other species 

 and is apparently without value as a specific character. 



Two spots of lighter colored scales upon the disc of the mesonotum have been 

 generally considered diagnostic for this species. We find that this character, 

 as in other similarly marked species, is evanescent and extremely unreliable. 

 Specimens without the spots have usually been wrongly identified. 



This species will have to be called Culex territans (see our remarks on page 

 300). 



CULEX BARBARUS Dyar & Knab. 



Culex barbarus Dyar & Knab, Journ. N. Y. Ent. Soc, xiv, 205, 210, 1906. 



Originax, Description of Culex barbarus : 



Very nearly allied to C. cubensis Bigot, but the air tube much stouter. The lateral 

 hairs are in twos after the second abdominal segment, the subdorsal ones also in 

 twos. Tracheae broad. 



A single specimen was collected by Mr. Busck in a lagoon pool far from habitation 

 on the South coast of Trinidad. It was named " Culex pipiens L." by Mr. Coquillett.
