In Trinidad Joblotia digitata, Rond., generally oviposits in the rain- 

 water accumulated in the broken cacao pods in shady parts of the cacao 

 field. The eggs float on the surface of the water in masses of 25-40, 

 and hatch in 8-10 hours after oviposition. The process of oviposition 

 is described.

The exact degree of difference constituting a species and a geographical 

 race or variety is more or less a matter of individual opinion. In some 

 details the author considers it necessary to dissent from Edwards' 

 conclusions [R.A.E., B, x, 17]. He disapproves of the European 

 form of Aedes pullatus, Coq., being called var. jugornm, Vill., as the 

 characters cited appear to be without special value. A . intnidens, Dyar, 

 is considered to be easily separated from A . pnllatiis or A . communis, 

 DeG. If A. sticticns, Meig., is to replace any American name, it will be 

 hirsuteron, Theo., of which aestivalis, Dyar, is probably a synonym ; it 

 is not a synonym of aldrichi, D & K., as Edwards thought possible. 

 With regard to A.punctor, Kirby, it is thought that the European form 

 should be called A . meigenamts, Dyar, and that A . puncior is its American 

 representative. A. lazarensis, F. & Y., is considered by Edwards to 

 be a synonym of A. communis, DeG., and A. tahoensis, Dyar, and 

 A . pionips, Dyar, as possible synonyms ; the first two are, however, 

 thought to be races, and should stand as A. communis lazarensis 

 and A. communis tahoensis, while A. pionips is a distinct species. 

 A. lesnei, Seguy, is the same as either A. semicantans, Mart., or 

 A . freyi, Edw. , and not a synonym of the black-legged A . sticticus, Meig. , 

 as doubtfully referred by Edwards. The species which Edwards calls 

 A. excrucians, Wlk. {surcoufi, Theo. ?), differs from the American 

 excrucians in the larval characters, and therefore if the identity of 

 surcoufi cannot be ascertained a new name will be required. With 

 reference to Edwards' A. alpinus, L. {innuitus, D. & K., and nearcticus, 

 D.), and A. parvulns, Edw., the author considers the synonymy 

 should be A. alpinus, L. {innuitus, D. & K.), and A. nearcticus, D. 

 {parvulus, Edw.).

This list of the mosquitos found in the mountains of Montana forms 

 a supplement to a previous one, in which the species occurring in the 

 plains were dealt with [R. A.E., B, vi, 8].

The species dealt with include Aedes iridipennis, sp. n., a female of 

 which is described from Arizona at an altitude of 6,100 feet; A.
