902 MOSQUITOES OF NORTH AMERICA 



female (the abdomen of my female specimen is somewhat injured). Thorax brown- 

 ish-tawny, darker above, paler on the pleurae; a metallic blue longitudinal line 

 along the middle of the thorax reaches the scutellum; three similar marks on the 

 pleurae, the upper of which is in the shape of a short line running from the base of 

 the wing towards the head. Abdomen brownish above, paler below; knob of the 

 halteres brown, stem pale. Feet brownish, paler at the base; a snow-white dot on 

 the upper side of the tip of the femora and of the tibiae; when looked at very 

 obliquely these white dots appear slightly pale bluish, and the tibiae and tarsi 

 likewise show a faint bluish reflection. Wings clothed with brown scales, but 

 showing, in an oblique light, numerous blue reflections especially a stripe near the 

 basis, between the third and fourth longitudinal veins. (Washington, D. C; Brook- 

 lyn, N. Y., by Mr. Brevoort.) 



Observation. — In my female specimen the scales are somewhat rubbed off on the 

 feet, which for this reason appear pale-tawny; still the white dots are distinctly 

 visible. 



Description or Femat.e, Male, Laeva, and Pupa op Ubanot^nia sapphibintjs : 



Female. — Proboscis rather long and slender, much dilated at apex, with 

 numerous fine cilia; vestiture of black scales. Palpi very short and stout, 

 clavate, clothed with black scales and with scattered long black bristles. An- 

 tennae long and slender, the joints subequal, rugose, brown, with long and coarse 

 ciliation ; second joint slightly thickened ; hairs of whorls rather long, sparse ; 

 tori globose, with an apical excavation, ocherous with a dark-brown spot on inner 

 side. Clypeus large, convex, broadly conical, constricted at base, brown. Eyes 

 narrowed above, not contiguous. Occiput covered with broad flat recumbent 

 scales, broadly metallic violet-blue in front and at the sides, posteriorly black 

 and brown ; bristles along margins of eyes coarse, long, black, directed forward. 



Prothoracic lobes well separated, large and prominent, contiguous with the 

 head, covered with broad, flat, metallic violet-blue scales, and with a few coarse 

 black bristles. Mesonotum rich yellow-brown with a dark median longitudinal 

 stripe; clothed rather sparsely with minute hair-like bronzy brown scales, a 

 median line of broad, flat, brilliant metallic blue scales extends the entire length 

 of the mesonotimi and is continued by a broader patch on the scutellum ; there 

 are marginal stripes of brilliant blue scales beginning about one-third from the 

 anterior angles and terminating at roots of wings; bristles coarse and long, 

 black, in subdorsal and lateral series. Scutellum with the median lobe very 

 large, broadly rounded, the lateral angles prominent ; lateral lobes clothed witii 

 outstanding, clavate, dark brown scales, middle lobe brUliant blue scaled; 

 each lobe with a few coarse long setae. Postnotum yellow-brown, large and 

 broad, nude. Pleurae brownish yellow with a large patch of broad, brilliant 

 metallic blue scales at the middle, coxae luteous ; pleural bristles coarse, brown. 



Abdomen subcylindrical, depressed, broad, nearly parallel sided, apex trun- 

 cate; dorsal vestiture of dusky scales with greenish-blue iridescence in some 

 lights; third, fifth, and sixth segments with a median apical patch of dirty- 

 white scales, that on fifth very broad ; fifth and sixth segments with hind angles 

 white marked ; ventral vestiture of dirty whitish scales ; distal segments with 

 scattered fine pale cilia ; marginal cilia of segments sparse, coarse, long at sides, 

 pale. 



Wings rather broad, hyaline; second marginal cell small, about one-third 

 as long as its petiole ; second posterior cell longer, but shorter than its petiole ; 

 basal cross- vein more than its own length from anterior cross-vein; scales of 

 veins small, broadly truncate, brown ; fifth vein with basal half broadly clothed 

 with broad brilliant metallic pale blue scales, much larger than the brown 

 scales ; a short patch of similar scales at root of first vein ; second, third, fourth 

 and upper branch of fifth veins with large, outstanding lanceolate scales, very 

 pale on all but basal two-thirds of second vein; fringe broad. Halteres whitish, 

 knobs dark and clothed with dusky scales.
