of 4 hairs of different lengths on each side ; ventral brush large, confined by the 

 ehitiaous plate. Anal gills small, subequal, pointed. 



The larvas live in ground-pools. Dr. Grabham has sent us specimens bred 

 from tanks at Newcastle, elevation 4000 feet, which shows that they will also live 

 in artificial receptacles, as would be expected. Theobald gives the following in- 

 formation, obtained from Dr. Grabham, on the habits : 



It is an inland species, and is recorded from Cinchona and Mavis Bank, 

 between 3500 and 4000 feet altitude; a few stray specimens have been taken by 

 Dr. Grabham in the Eed Hills and in Kingston. It appears in great numbers 

 at certain times, especially after heavy autumnal rains. Great numbers bred 

 in the pools at the foot of the Red Hills near Kingston in the autumn of 1899. 

 The adults have a slow and clumsy flight, and appear in clouds following one 

 about. It is a persistent and vicious biter, biting during the daytime. The bites 

 cause painful swellings.

Culex quasisecutor differs in having spottings on the mesonotum, a common 

 variation, which occurs in many species of Culex and is without specific value. 

 Theobald, in defining this supposed species, mentions also a difference in length 

 in the last joint of the palpi of the male ; but this is an illusory character, as it 

 is very difi&cult to estimate such a proportion in the curved and often shrunken 

 and distorted organ as it occurs in cabinet specimens. Our series of secutor 

 received from Dr. Grabham, and bred from the same lot of larvae, contains both 

 the spotted and unspotted forms. Theobald quotes Dr. Grabham as saying that 

 there are larval differences between the forms, a statement surely due to some 

 error or confusion. The record of the species from Sao Paulo, Brazil, by Pery- 

 assu, is undoubtedly based upon a misidentification. If the species had a wide 

 distribution we would surely have received it from other localities and this has 

 not been the case.

Obiginai. Description of Ctnjx cobonatob: 



AntennsB with the tuft slightly beyond the middle, pale; head hairs, the upper in 

 four or five, the lower in three or four, rarely five; body hairy. Air tube long, 9X1, 

 the pecten reaching two-fifths, a crown of coarse spikes before apex, usually well 

 developed, sometimes nearly obsolete. Anal gills moderate. 



An abundant species throughout the tropics, apparently absent from the islands. 

 Mr. Busck took it in a pool in the woods at St. Joseph, Trinidad, in a lagoon pool on 

 the south side of Trinidad, in a bucket with live crabs and an open ditch in the 

 middle of the village, Cedros, Trinidad. The junior author found this the commonest 

 species in Mexico and Central America. The localities are: puddles in street, shallow
