Sta., Rept. Mosq., 280, fig 86, 1805)- While it is possible that this 

 is the true serratus of Theobald, described from Brazil and Guiana, we 

 do not think it is probable, especially in view of what we note under 

 Aedes tormentor above. We therefore propose a new name for the 

 Atlantic coast form. Prof. Smith has taken it in New Jersey and 

 the senior author at Sanford, Florida. 



Aedes inconspicuus Grossbeck. 



Culex inconspicuus Grossbeck, Ent. News, xv, 313, 1904. 



Culex inconspicuus Smith & Grossbeck, Psyche, xii, 18, 1905. 



Culex inconspicuus Smith, N. J. Agr. Exp. Sta., Rept. Mosq., 297, 1905. 



One of the Spring species detected by Mr. Grossbeck. Its range is 

 unknown, as no other specimens have been collected. 



Aedes hemisurus, new species. 



This is the species figured by Dr. Grabham from Jamaica (Can. ent., 

 xxxvii, 405, 1905) as "Culex confirmatus Arrib." We do not believe 

 that the insular form can be conspecific with the one described from 

 the Argentine, especially as it is very different from the one identified 

 as confirmatus from the United States. (See Aedes infirmatus above) 

 We therefore propose a new name. 



Aedes euplocamus, new species. Fig. 16. 



Antennal tuft small, at the middle; head hairs single. Air tube a 

 little over 2 x 1 with even pecten of 1 2 teeth to the middle. Anal seg- 

 ment ringed; gills long, pointed, spotted. 



Collected by the junior author at Zent, near Port Limon, Costa Rica, 

 in a ditch. It was named ''Culex trivittatus Coq.' ' by Mr. Coquillett, 

 but the larva disagrees. 



Aedes fitchii Felt & Young. 



Culex fitchii Felt & Young, Science n. s., xx. 505, 1904. 

 Culex fitchii Felt, Bull. 79, N. Y. Sta. Mus., 282, 1904. 

 Culex siphonalis Grossbeck, Can. ent., xxvi, 332, 1904. 

 Culex fitchii Dyar, Journ. N. Y. ent. soc, xii, 246, 1904. 



One of our early Spring forms with northern distribution. The 

 larva is readily recognizable by the long tube and the narrow angled 

 tracheae.
