912 MOSQIHTOES OF NORTH AMERICA 



Oiservations. — Described from two specimens sent by Dr. Low to Dr. Rees. It 

 is a very distinct species, which can be easily told by the thoracic ornamentation 

 and the white hind tarsi. Dr. Low bred them from larvae taken in a pool at the 

 Cemetery, St. Lucia, and mentions that the larva is peculiar. 



Origin AL Desckiption of UBANOTiENiA minuta: 



Head deep brown in the middle, azure blue at the sides and in front. 



Thorax dark brown in the middle, pale brown at the sides, with a patch of flat 

 azure blue scales in front of the roots of the wings. Abdomen brown, some of the 

 segments with apical lateral pale blue spots. Legs deep brown, the hind pair with 

 the apical half of the third tarsal, whole of the fourth white and the fifth white 

 in some lights, dusky in others. Wings with a pale blue patch at the base. 



?. Head deep brown, clothed in the middle with flat deep velvety-brown scales 

 and with flat azure blue ones at the sides and a few forming a median patch in 

 front; antennae deep brown; also the proboscis, which is much swollen apically. 



Thorax deep brown in the middle, bright brown at the sides, clothed with bronzy 

 curved scales which are broader on the dark area than on the pale, a line of pale blue 

 flat scales on each side in front of the roots of the wings, and pale blue scales on 

 the prothoracic lobes, chstee long, brown; pleurae brown, with pale blue puncta; 

 scutellum pale brown, with four border-bristles to the mid lobe (denuded). 



Abdomen deep brown, with three ( ?four) apical pale blue lateral spots and short 

 brown border-bristles. 



Legs deep brown, with violet and purple reflections. In some lights bronzy; the 

 hind legs have the apical half of the third tarsal, and whole of the fourth snowy- 

 white, the fifth appears white in some lights, dusky in others; ungues equal and 

 simple. 



Wings with brown scales, the lateral ones scanty, long and thin, a line of fiat 

 azure-blue scales at the base of the fifth vein; median vein-scales single, very nar- 

 row; costa spiny, dark brown; first sub-marginal cell smaller and narrower than the 

 second posterior, its base nearer the apex of the wing, its stem about three and a 

 half times as long as the cell, close to the first long vein; stem of the second pos- 

 terior not quite twice as long as the cell; the supernumerary vein longer than the 

 mid and sloping backwards; the posterior as long as the mid, about one and a-half 

 times its own length distant from it; joining the upper branch of the fifth at about 

 its own length distant from the fork, the upper branch of the fifth bending sharply 

 where it joins it; the wings are pale at the base; halteres with pale stem and 

 fuscous knob. 



Length. — 2 mm. 



Time of capture. — ^January. 



Babitat. — New Amsterdam, British Guiana (Dr. Rowland). 



Oltservations. — Described from a perfect ?, except that the scutellum Is rubbed. 

 It Is a very small species, easily told by the cephalic adornment, the white hind 

 tarsals and non-banded abdomen, with apical pale blue scales. The blue area at the 

 base of the wing is on the fourth and fifth veins. The antennae appear very long. 



Description of Femai^e, Mai.e, and Labva of Uranot.s!nia Lown: 



Female. — Proboscis moderately long, apical third much dilated, labellas 

 large, entire length ciliate; vestiture of deep brown scales. Palpi very short, 

 stout, clavate, with a few coarse long bristles and clothed with dusky scales. 

 Antennae filiform, long and slender, the joints subequal, with coarse but sparse 

 ciliation ; hairs of whorls rather short, sparse, black ; tori globose, with an apical 

 excavation, yellow and brown. Clypeus prominent, broadly conical, constricted 

 at base, brown. Occiput clothed with flat recumbent black scales with a slight 

 iridescence, in front a median triangular patch of bluish-silvery scales, on each 

 side and contiguous with this a broad band of bluish-silvery scales runs from 

 ocular margins obliquely to base of prothoracic lobes ; bristles along margins of 

 eyes coarse, black. 



Prothoracic lobes large and prominent but well separated, contiguous with 

 head, clothed with broad flat silvery scales with a bluish or violaceous irides- 

 cence and with a few black bristles. Mesonotum bright yellow-brown with three 

 dorsal longitudinal darker stripes, two shining bare stripes between them show- 

 ing a pale greyish or bluish tinge, at sides over roots of wings a large dark 

 brown spot; vestiture of sparse, blackish, rather large hair-like scales; these
