38 The Mosquitoes or Culicidae of Jamaica. 



also large, flat scales before the scutellum. A few grey scales 

 in front over the head; prothoracic lobes clothed with small, 

 flat, brown scales above, with dull silvery white ones below; 

 a patch of small, flat, silvery-white scales on each side of the 

 mesonotum in front, scarcely showing in the dorsal view ; 

 scutellum testaceous, clothed with small, flat, dull brownish 

 violet, spatulate scales and brown border-bristles ; metanotuin 

 deep to bright brown according to the light, with a few chaetae 

 arising from black spots towards its apex ; pleurae ochraceous, 

 with patches of small, white, flat scales. 



Abdomen blackish, the scales showing dull violet reflections, 

 border-bristles very small and pallid ; venter entirely clothed 

 with dull white scales and a few black ones apically, and with 

 many straight black bristles at the apex. 



Legs long and thin, deep blackish brown with bronzy reflec- 

 tions, the hind femora dilated apically, the last three mid tarsi 

 and the apex of the first silvery white on one side, except just at 

 the apex of the last segment ; ungues small, equal and simple. 

 Wings with brown scales, those on the apex of the two branches 

 of the second long vein slightly broadened, some of the other 

 lateral vein-scales long and rather thin, especially on the stem of 

 the second and on the fourth ; first sub-marginal cell considerably 

 longer and a little narrower than the second porterior cell, its 

 base nearer the base of the wing than that of the latter cell, its 

 stem about one-third the length of the cell ; stem of the second 

 posterior cell about two-thirds the length of the cell ; posterior 

 cross- vein longer than the mid cross- vein, about half its own length 

 distant from it ; mid and supernumerary cross- veins almost in a 

 straight line. Halteres with pale ochraceous stem and fuscous 

 knob. 



Length. 4 mm. 



Time of capture. January (1904). 



Habitat. Jamaica. 



Observations. Described from a single perfect female taken 

 by Dr. Grabham. It can at once be identified by the white mid 

 tarsi. This appears to be on one side only, apparently the upper 

 surface. 



It can be at once told from the other species by the above 

 character and the cephalic adornment. No special notes have 

 been made on this insect. There are more lateral linear scales 

 to the wings than in the type of the genus, but it more nearly 

 approaches Dendromyia than Wyeomyia.
