cies of mosquitoes whose larvae normally live in the water in hollow 

 trees, Pneumaculex sign if er Coq. and Grabhamia triseriata Say, I have 

 shown that the latter hibernate in the egg state. The former, it now 

 appears, hibernate in the larval state. Mr. Busck brought a number 

 of P. signifer larvae from St. Louis in the Fall and they showed no 

 disposition to transform. The two predaceous species of the hollow 

 trees, AnopJieles barberi Coq. and Megarhinus portoricensis von Rod. 

 likewise hibernate as larvse. I have observed this in the case of the 

 Anopheles formerly and Mr. Busck's Megarhinus, brought with the 

 Pneumaculex, has lived all winter in the laboratory. It would appear 

 as if the Pneumaculex, must suffer more from the predaceous habits of 

 the other species that the Grabhamia does, since it is longer coexist- 

 ent with them in the larval state. 



Relationship of Culex inconspicuus Grossbeck. — The figures 

 of fragments of the larva of this species given on page 297 of Smith's 

 Report on Mosquitoes (1905) show it to be allied to the species de- 

 scribed by Felt and Young as Culex lazarensis. However, the male 

 genitalia of inconspicuus as figured differ from those of lazarensis as 

 figured even to a generic degree. Inconspicuus falls in Culicelsa while 

 lazarensis belongs to Grabhamia. This looks like a disagreement 

 between larval and genitalic characters which is unusual, and may 

 indicate that the genus Culicelsa is not well founded or that the asso- 

 ciation of larvae and adults under C. inconspicuus is inaccurate (see 

 also Proc. ent. soc. Wash., vii, 48, 1905). 



Generic location of Culex discolor Coq. — I included this 

 species among the unidentified list under the genus Grabhamia (Proc. 

 ent. soc. Wash., vii, 48, 1905), but Smith's figures recently at hand 

 show it to be referable to the genus Feltidia. The larva differs from 

 the other larva? of Feltidia known to us, among other things, in that 

 the air tube is not inflated. Its characters are, as it were, curiously 

 reversed, for it is the antennas, on the opposite end of the larva, that 

 are inflated. 



Deinoceritf.s cancer Theob. in the United States. — In a 

 recent brief tour of Florida by Mr. Caudell and myself, this Jamaican 

 species was discovered at Miami. Dr. Grabham describes the larva as 

 living in crab holes, and these were accordingly searched. At the time 

 of our visit (March), there had been no rain for weeks and all the holes 

 were dry, so that, except for a fortuitous circumstance, the species would 

 have been missed. It happened that opposite Miami a canal is being
