central part and yellowish at the extreme ends while the tarsi are 

 wholly yellow. The claws of the male anterior tarsal joint (fig. 

 114, 2) are simple, ver\^ slender and slightly unequal; the mid 

 and posterior, as are all the claws of the female are equal, sim- 

 ple and very slender. The wings are rather broad, the veins 

 clothed with long yellow and blackish hair-like scales, the black- 

 ish ones fonning two broad transverse bands, the jfirst, one-third 

 from the base; the second, two-thirds from the base; near the 

 posterior margin of the wings the veins are more or less clothed 

 with blackish scales, so as to connect the cross bands. The 

 fringe is white, with a blackish portion at the posterior end of 

 each cross band and another at the apex of the wing. 



The abdomen is ver)^ dark brown, with numerous yellow hairs 

 scattered over the surface. 



Habits of the Adult. 



Practically nothing is known of the habits of this little mos- 

 quito except that it does not bite because it cannot. Its very 

 small size makes it difficult of recognition in general collecting, 

 hence all our examples are bred specimens. So far as I am 

 aware all the known examples are from Lahaway or Delair, and 

 the species may be ignored from the economic standpoint. 



Description of the Larva. 



The larA^a, with the under side of the head greatly enlarged, 

 is illustrated on plate iii, 6. When full grown it averages be- 

 tween 3-4 mm., = .12-. 16 of an inch in length, exclusive 

 of the anal siphon, and is of a rust brown color, except for nar- 

 row, white, transverse lines which cross the thorax and abdomen. 

 The head is much broader than long, rounded at the sides, slightly 

 excavated before the insertion of the antennas and flat in front; 

 on each side a transverse row of about twelve short spines, di- 

 rected anteriorly. The antennae are situated close together on 

 prominences in the anterior part of the head, and project later- 

 ally; they are moderately long, almost straight, with three long 

 curved and one very short spine at the apex. The figure of the 

 under side of the head shows the mandibles and mentum. The 

 mandible is rather stout and chunky, provided with stout teeth at 

 its apex, and a few spines on its dorsal surface; a curious fan- 

 shaped arrangement of flat spines is also' attached to one of the
