Melanoconium atratum Blanchard, I.es Moustiques, 395, 1905. 



Melanoconion atratus Grabham, Can. ent., xxxvii, 403, 1905. 



The larva has been made known by Dr. Grabham. His first com- 

 munication is accompanied by a plate (Mon Culic, iii, pi. xvi) which, 

 however, gives no adecmate idea of the species, so that the senior 

 author was led to accept one of Mr. Coquillett's determinations, and 

 published a description of another larva under this name. (See Journ. 

 N. Y. ent. soc, xiii, 29, 1905, and compare Mochlostyrax erraticus of 

 this paper). 



Culex carcinophilus, new species. Fig. si- 

 Antennae with the tuft beyond the middle, dark ; upper head tuft 

 multiple, lower single; body spicular, not pilose; lateral hairs in twos 

 on the second abdominal segment, in threes on the third to sixth. 

 Air tube very long, 10 x 1, straight; four small, two-haired tufts on 

 posterior margin ; pecten of long spines outwardly, reaching to one- 

 sixth. Lateral comb of the eighth segment large; anal gills very 

 small. 



Collected by Mr. Busck from crab holes containing fresh water near 

 San Domingo City. The adults were named "Melanoconion atratus 

 Theob.' ' 



Culex daumasturus, new species. Fig. 52. 



Distinct from any known larva by the very long air tube (12 x 1) 

 with a swelling at the outer third. 



It was collected by Mr. Busck in the leaf corner of a Century 

 Plant near the pitch lake, La Brea, Trinidad. A second specimen 

 has been sent us by Mr. Urich from Bromelias at Arima, Trinidad. 

 The adult was named "Culex imitator Theob." by Mr. Coquillett, 

 and it may be that species, which was bred from Bromelia water by 

 Dr. Dutz in Brazil; but we do not feel certain enough of it to accept 

 the name. 



Culex vector, new species. Fig. 53. 



Antennae with the tuft at the outer third, pale; body glabrous; lat- 

 eral abdominal hairs in four on first segment, twos on second, fours
