Described from Mexico and Mississippi. Our larvae are from Baton 

 Rouge, Louisiana, from Dr. Dupree. 



Janthinosoma infine, new species. Fig. i. 



The characters are normal for the genus The antennae are great- 

 ly developed, the anal segment short, the scales of the lateral comb 

 of the eighth segment are joined by a very weak chitinous band ; the 

 single scale has its apical spinule long. The larva? were collected 

 by Mr. Busck in Trinidad and St. Domingo in rain water pools 

 and ditches, in a spring in a cave, in a slowly running spring, 

 in a pot-hole in coral rock in the woods, in a pot-hole near the 

 coast with rather salt water and in holes made by wild pigs in the 

 vSan Francisco Mts. of St. Domingo. The specimens have been named 

 'Culex c >nji>iis," but confinis was described by Arribalzaga from the 

 Argentine and is referred by Blanchard to Tceniorkynckus ; so we do 

 not accept the identification .

 Culex scholasticus Blanchard, Les Moustiques, 336, 1905. 



Described from the Antilles. Our specimens are from Trinidad, 

 taken by Mr. Busck in rain water pools at Cedros, with the preceding 

 species. We have accepted this identification, although it is per- 

 haps open to some doubt, as Mr. Coquillett later applied this same 

 name (scholasticus) to a very different species, collected by 

 the junior author in Central America, which same species he had also 

 named "secutor Theob." Not, however, the true secutor Theob. of 

 Jamaica, of which we have specimens from Dr. Graham. (See Culex 

 lactator and C. coronator described below). 



Janthinosoma pvgmaea Theobald. Fig. 3. 

 Grabhamia pygmcea Theobald, Mon. Culic, iii, 245, 1903. 



Described from Antigua and Jamaica. Our specimens were taken 

 by Mr. Busck in St. Domingo in pools in coral rock close to the sea, 

 filled with clear salt water, only submerged by the highest tides. 

 We have accepted the determination because we do not know but 

 that Theobald's specimens came from larvae with the same peculiar 

 habits as ours ; this is not stated, and we give the matter the benefit 

 of the doubt.
