clean water generally. It is an active, robust, dark larva, with 

 short, very robust and very spiny antennae. 



The larvae of C. triseriatus were found in an iron pail half 

 filled with rain water. They are at once recognizable by the in- 

 tensely black head and the short black anal tube. The body is 

 slender and white and the motions are slower, less jerky than 

 those of the other species. The resemblance is to the larva of 

 Stegomyia fasciata. The labium is quite distinct in form and 

 the antennae are very long, very slender and almost bare. 



C. atropalpus is closely allied and only a little smaller. There 

 is an obvious difference in the labium and the antennae are 

 shorter, stouter and somewhat hairy. The larvae were taken 

 in pools in the rocks on the coast of Maine by my little boy and 

 carried to me at 'New Brunswick. Mr. Coquillett writes me 

 that the species is found near Washington, and its occurrence 

 in New Jersey is therefore probable. 



Three species so closely resembling each other in the adult 

 stage that all were at first supposed to be sylvestris were bred 

 from very obviously different larvae. 



From Delair, N. J. , I received large numbers of a rather stout, 

 white larva with a short brown anal siphon, found everywhere 

 in pools and ponds, and I bred out a large number of adults. 

 The antennae were rather slender, only a little hairy, and the 

 labium was in general accord with that of the cantans and its 

 allies. 



From the vicinity of Newark Mr. E. L. Dickerson, my as- 

 sistant, brought in a stout active larva with a short anal siphon 

 and a very short, stout, hairy antenna. The labium is dis- 

 tinctly different from the usual ring-legged type, but the adults 

 bred from this batch were supposed to be sylvestris at first sight. 

 They proved different on further study and the species has not 

 yet been determined. 



From the salt meadows near Elizabeth, Mr. H. H. Brehme, 

 who explored this territory for me, sent large quantities of larvae 

 which at first appeared to be all sollicitans. When adults began 

 to issue two species were noted and it was found that two forms 

 of larvae could be recognized : — one in which the head was im- 

 maculate, and another in which it was maculate — the most per-
