he has failed to observe that it is a synonym of curriei, which he 

 places in Grabhamia. C. trichurus Dyar and C. cinereohorealis Felt 

 are treated separately, but are really one species. Under C. punctor, 

 we are told " the American observers take a wholly different insect to 

 he punciorio that placed in the Museum collection;" but not a char- 

 acter is given to enable us to correct our error, if indeed Mr. Theo- 

 bald means to imply that we are in error, which is not at all clear 

 from the peculiar wording. Punctor is even carefully omitted from 

 the table, which, by the way, is stated to be "complete." 



Ciiliseta Felt is used, although it is synonymous with Theobaldia ; 

 but Mr. Theobald has "been unable to work out the two included 

 species," from lack of time, we suppose. 



Culex, as now restricted, has very nearly the same extent as defined 

 by us, the genitalia being referred to. Some discordant elements are 

 included, such as ati'opalpus Coq., sylvestris Theob., niveitarsis Coq. 

 (which may be only an aberration of canadensis, as Miss Ludlow has 

 suggested to us), tortilis Theob. and inconspicuus Grossb. for most of 

 which there is no excuse, as sufficient data have been published to ex- 

 clude these species from Culex if Mr. Theobald had chosen to notice 

 the literature. He states that the genitalia oi sylvestris " are no more 

 varied than one finds in other closely related species of Cu/ex," which 

 is certainly a remarkable statement, as Felt has founded a genus on 

 them. They are in reality very aberrant. Culex sulifuscus is founded 

 on a single male. Anyone familiar with the species of Culex, their 

 very close affinity and the diversity of the sexes will appreciate the 

 impossibility of associating the proper female with this form. Culex 

 similis, which was originally founded on females from Jamaica, now 

 receives a supplementary description of a male from British Guiana. 

 We feel sure that this is really not the same species, for in our experi- 

 ence, with the exception of one or two semi -domestic species, those 

 found in the West India Islands are distinct from those of the main- 

 land. Culex quasisecutor is merely a maculate form of secutor and 

 not a new species. A similar variation occurs in C. restuans Theob. 

 and again in C. territans Walk. 



Protoculex Felt is used for serratus, dupreei and a new species, 

 quasiserratus, the latter obviously a synonym oi pertinax Grabham. 



The appendages of the male antennae in Lophocetatoniyia are most 

 curious, but it is very doubtful if the genus is a good one, as these 

 characters are not correspondingly developed in the female.
