the name subcantans* (p. 474) for the American species heretofore 

 known as cantans Meig. The genitalia of our form are found to differ 

 from those of the European species, specimens of which Dr. Felt has 

 received from Dr. F. Meinert. This agrees with what we had anti- 

 cipated (Journ. N. Y. ent. soc, xiii, 51, 1905) and we congratulate 

 Dr. Felt on being able to demonstrate it. We notice some discrep- 

 ancies between the figures of the genitalia of fitchii and abfitchii and 

 our own figures of these species, recently published in this Journal. 

 These concern the filament of the harpe, a very delicate structure, the 

 shape of which may be apparently altered by differences in the excel- 

 lence of the preparation. We think our figure of fitchii is the better, 

 while Dr. Felt has evidently secured a better illustration of. abfitchii 

 than we did. 



Notes on Sonic Jamaica)! Culicidez. By M. Grabham, M.A., M.B.,

 Entomologist, xxxvii, 401-41 1, 1905. 



We desire to notice Dr. Grabham's paper, principally because he 

 has illustrated the very parts of the mosquito larvae which we want to 

 know about, and we are able to place nearly all the species he de- 

 scribes at once in our tables. But the larva? do not agree with those 

 that we have had (and in some cases described) under these names. 

 We believe that in no case is there an agreement. Dr. Grabham 

 describes Uranotcenia lowii Theob., and U. socialis Theob., but we can 

 not make either agree with Miss Mitchell's detailed separation of these 

 forms as they occur in New Orleans. Melanoc onion atratus Theob. 

 does not agree ; our larva has a pilose body and shorter air tube. 

 Culex confirmatus Arrib. is widely different from the continental form ; 

 our larva is glabrous and the pecten of the air tube runs only half way. 

 Culex janitor Theob., is still more different ; we have a larva with a 

 long air tube and antennal tuft at the outer fourth arising from a set- 

 off as in seen tor. Culex microsquamosus Theob. is a new species and 

 the larva new to us. There can be no argument about this one. 

 Janthinosoma jonstonii Grabham is described without larva. Now all 

 this discrepancy means either that the larva? are variable, in which case 

 we can not separate one Culicid larva from another, or that somebody's 

 determinations are faulty. Dr. Grabham's adults were, we presume, 



* I!ut the stimulans of Walker, heretofore referred to the synonymy of cantans, 

 has yet to be accounted for.
