TABLES OF UESTICOCAMPA 163 



slightly more plumose in the male than in the female. Vestlture of flat, appressed 

 scales, the head with a collar-like row of upright forked-scales on the nape. Meso- 

 notum without setse on the disk. Prothoracic lobes moderate, well separated dor- 

 sally. Abdomen subcylindrical, blunt at the tip. Legs long and slender, the hind 

 ones ciliate in some species; claws small, equal and simple in the female, one claw 

 of the hind pair very slender in some species; in the male unequal on the front and 

 mid legs, some of them modified. 



Genekec Diagnosis of LiAbva: 



Maxillae prominent, elongate, visible from above, armed with two large, unequal 

 terminal teeth; air-tube spiculate, with a fringe of fine hair along the posterior 

 margin ; lateral comb of the eighth segment of few or many scales, either in a single 

 row or in a patch; anal segment with dorsal plate and pair of subventral tufts; anal 

 gills well developed. 



Forested regions of tropical America. 



The genus Lesticocampa has been recognized by Theobald and authors follow- 

 ing him under the name Johloiia Blanchard. This is inadmissible, since 

 Joblotia was proposed as a substitute for Trichoprosopon Theobald, which was 

 considered preoccupied by Trichoprosopus Macquart. Lutz considered both 

 names allowable, and proposed to use Joilotin for the forms here classified under 

 Lesticocampa, which had been wrongly associated with Trichoprosopon= 

 Joblotia. But as Blanchard has specified nivipes Theobald {=digitatus 

 Eondani) as the type of Joblotia, any change is inadmissible. The statement 

 of Theobald concerning the type species of Lesticocampa, Wyeomyia lunata 

 Theobald, that "the hairs on the clypeus are quite distinct" (Mon. Culic, iii, 

 336, 1903) proves to be erroneous, and is corrected by him (Mon. Culicid., iv, 

 594, 1907) ; although afterwards again contradicted (Mon. Culie., v, 557, 1910) 

 it is once more corrected (Mon. Culic, v, 621, 1910). 



The larvse are predaceous upon those of species of Oulex or Wyeomyia living 

 in the water between the flower-sheaths or leaves of different plants. These 

 places often contain but little water and that of a sHmy character. The larvse 

 are apparently wholly predaceous in their habits; they occur singly and the 

 species are comparatively rare. The habits of the adults are unknown to us.
