includes the name in his list of uncertain or indeterminable species, 

 but Coquillett is apparently able to recognize it. The larvae occurred 

 in a temporary pool full of vegetation, together with many Culicid 

 larvae on which they were feeding. 



Psorophora ciliata Fabricius. 



Culex ciliatus Fabricius, Ent. Syst., iv, 401, 1794. 



Culex molestus Wiedemann, Dipt, exot., i, 36, 1821. 



Psorophora boscii Desvoidy, Mem. soc. d'hist. nat. Paris, iii, 413, 1827. 



Culex conterrens Walker, Ins. Saund., Dipt., i, 427, 1856. 



CuleiL perterrens Walker, Ins. Saund., Dipt., i, 431, 1856. 



Psorophora ciliata Blanchard, Les Moustiques, 239, 1905. 



The species occurs in the Atlantic seaboard as far North as Mass- 

 achusetts, and is common locally at Baltimore and Washington. 

 The larva occurs in temporary rain puddles, hatching immediately 

 after a shower. It is predaceous and very voracious. The principal 

 prev are the species of Janikinosoma. 



Psorophora hovvardii Coquillett. 



Psorophora howardii Coquillett, Can. ent., xxxiii, 258, 1901. 



Occurs on the Atlantic and Gulf coasts, but does not extend its 

 range so far to the North as ciliata. The habits are the same and the 

 two species occur mixed in the same puddles. The larvae are very 

 similar. In Mexico, the junior author found howardii considerably 

 more abundant than ciliata, while in Central America howardii 

 occurred alone. 



Genus LUTZIA Theobald. 



Lutzia Theobald, Mon. Culie., iii, 155, 1903. 



Lutzia bigotii Bellardi. 



Culex bigotii Bellardi, Mem. d. R. accad. di Torino, xxi, 200, 1864. 

 Culex bigotii Blanchard, Les Moustiques, 275, 1905. 

 Lutzia bigotii Blanchard, Les Moustiques, 394, 1905. 



This interesting larva has the predaceous habits of Psorophora and 

 in the main agrees structurally therewith ; but in the less degree of 

 modification of the maxillae, lateral comb of the eighth segment and 

 pecten of the tube, retains more of the structural characters of the 

 other Culicid genera. The junior author collected it at Cordoba,
