30 INSECUTOR INSCITI^ M^NSTRUUS 



bristly," which would apply very well to a Culex, but certainly 

 not to an A'edes.

 Culex chalcocorystes Martini, Ins. Ins. Mens., ii, 70, 1914. 



The above synonymy may be mentioned, although not con- 

 nected with the work here noticed.

Genus PSOROPHORA Robineau-Desvoidy 



The authors would sink sayi D. & K. as a synonym of 

 posticatus Wied. An absolute synonym seems to overstate the 

 case, and here is a good opportunity for the subspecific con- 

 ception. The forms may be known as Psorophora posticatus 

 posticatus Weid. and Psorophora posticatus sayi D. & K. 



Aedes (Taeniorhynchus) fluviatilis Lutz. 



Culex fluviatilis Lutz in Bourroul, Mosq. do Brasil, 42, 72, 1904.

 Aedes soosophus Dyar & Knab, Ins. Ins. Mens., v, 165, 1918. 



I cannot detect any difference in the types of soosophus from 

 fluviatilis. The specimens came from the hilly region of cen- 

 tral Texas, where there is opportunity for the streams to form 

 pot-holes in the coral rock.
