 surface. Respiratory siphon a little more than twice as long 

 as broad. At each of the postero-lateral margins a row of 

 four short, two- to four-branched bristles. A pair of compound 

 plumose hairs at the upper border of the eighth segment, each 

 hair with six to seven trichae. A row of compound bristles at 

 the postero-lateral margin of the eighth segment, composed of 

 six to seven claw-shaped bristles, each with five to six stout 

 highly chitinised curved denticles. The long hairs on the thorax, 

 especially those on the posterior groups, are plumose. Lower lip 

 of Meinert with twelve to sixteen teeth on each side. The adult

Observations. — Giles has recently (1904) described this very 

 marked Grabhamia as a new Taeniorhynchus — T. antiguac — in 

 the Journal of Tropical Medicine. The type is in the British 

 Museum, and has been placed in its true position. 



I have not seen any specimens of Coquillett's Culex nan as. 

 He states that it is " near jamaicensis, but much smaller, etc." 

 From the short description it certainly reads as Grabhamia 

 pygmaea* This species was apparently not known to Coquillett 

 when he drew up the account of his Culex nanus in the September 

 number of the Canadian Entomologist.* Coquillett's description 



* Coquillett now places his nanus as a synonym of pygmaea (Class. 

 Mosq. N. and M. America, p. 22, 1906).
