Culex pleuristriatus Theobald. Fig. 22. 



Culex pleuristriatus Theobald, Mon. Culic, Hi, 177. J 9°3- 

 Culex pleuristriatus Bourroul, Mosq. do Brasil, 43, i9<>4- 



Described from Brazil. Mr.Coquillett has given us the name for a 

 specimen from Trinidad from Mr. F. W. Urich, bred from Bromeha 

 water. Its peculiar characters are indicated in the table. The mos- 

 quito fauna of the Bromelias is very rich, both in Sabethmes and 

 members of the genus Culex, as well as the Megarhinus that prey on 



them. 



Culex janitor Theobald. 



Culex janitor Theobald, Mon. Culic., hi, 182, 1903. 

 Culex janitor Grabham, Can. ent., xxxvii, 406, 1905. 



Described from Jamaica. Dr. Grabham figures the larva which we 

 have not seen in nature. Mr. Coquillett applied the name tentative- 

 ly to a very different species, to which we shall refer further on. 

 Culex lactator, new species. Fig. 23. 



With the characters given in the table ; a very distinct form. The 

 larva contradicts both the characters which usually define the species 

 of Culex but we nevertheless believe that it belongs here. The anal 

 segment has the normal structure of all the Culex species. 



The larvse were taken by the junior author in puddles at Cordoba, 

 Santa Lucrecia, Rincon Antonio, Tehuantepec and Almoloya, Mex- 

 ico • Puntarenas and San Jose, Costa Rica. The adults were named 

 "Culex-> secutor Theob." and mixed with another species (C. corona- 

 tor D. & K.) under this name. Compare our remarks under Culex 

 secutor and Janthinosoma scholasticus . 



Culex interrogator, new species. Fig. 24. 

 The antennse have the normal structure for Culex, but the air tube 

 is short as in Males. Its pecten is stout and runs to the apical fourth. 

 There are three hair tufts and a fourth smaller, placed laterally. 

 The comb of the eighth segment is in a long straight row, supplement- 

 ed by a second shorter one. The anal segment is normal. The skin 

 is pilose; the tracheae broad. 



Collected by the junior author at Rincon Antonio, Mexico, in ditch- 

 es The adults were named "Culex} salinarius Coq." by Mr. Co- 

 quillett with which species they have nothing whatever to do.
