706 MOSQUITOES OF NORTH AMERICA 



Thorax dark brown, the median portion (about one-third the width of the meso- 

 thorax) heavily covered with golden-brown slender curved scales; just exterior to 

 this on either side is a very narrow white line extending to the scutellum. There 

 are also two submedian very narrow white lines extending the whole length of 

 the mesothorax and curving around the " bare spot." Laterad the mesothorax is 

 densely covered with broader ochraceous scales, becoming white just over the wing 

 joint, and directly dorsad of this white spot is a large dark brown spot, suggesting 

 an " eye spot "; pleura dark brown, heavily scaled with broad curved light ochraceous 

 to v/hite scales; scutellum dark brown, with ochraceous slender curved scales and 

 numerous brown bristles; metanotum dark brown. 



Abdomen dark scaled, with a few light scales scattered irregularly through the 

 brown, and a heavy basal white spot very much deepened on the median line, so 

 that it curves down in the middle, and on some of the segments covers nearly one-half 

 the segment. There are also heavy basal lateral spots, but not always continuous 

 with the dorsal spot, which in most instances hardly creates a band. The last few 

 segments are much less heavily marked, but may have very narrow apical light 

 bands, which, however, do not usually extend all the way across; light apical 

 hairs on all segments. Venter mostly light scaled. 



Legs: coxae and trochanters all mostly light scaled. Femora all ventrally light, 

 but speckled, dark and light scales nearly equally mixed on the dorsal side, the 

 brown scales preponderating towards the apex, so that the femora are quite dark 

 near the distal end, but the apex itself has a ring of white scales, which, with a 

 few at the base of the tibiae, make distinct knee spots; tibiae somewhat darker 

 than the femora, the dark scales in excess, and growing more so towards the apex; 

 metatarsi dark, like tibiae, and all basally light-banded, but in the fore legs the 

 bands are not very distinct. All the tarsal joints basally light-banded, the bands 

 on mid and fore legs narrow, sometimes minute, and that on the last joint of the 

 fore legs sometimes missing; on the hind legs the bands are much broader and 

 conspicuous. All the ungues large, equal and uniserrate. 



Wings rather heavily covered with dark and light scales, both median and lateral 

 scales very heavy and spatulate on most of the veins, but those on the under side of 

 the wing are narrow. First submarginal cell longer and narrower than the second 

 posterior, bases nearly on a line; the stem of the first submarginal about one-third 

 the length of the cell. Supernumerary cross-vein a little longer than the mid, which 

 it meets at a marked angle: posterior cross-vein also a little longer than mid and 

 nearly twice its length distant. Halteres light with dark knobs. 



Length: 7 mm. Habitat: Benicia, Cal. Taken March, April and May. 



While this species lies near vittata, Theobald, and dorsalis, Meig., it differs from 

 the first in abdominal markings, in white scales on the two veins, etc., and from the 

 latter also in abdominal markings and in the tarsal banding, which in this species 

 does not include both sides of the joints. 



The specimens were sent in a series of collections by Dr. William F. de Niedmann, 

 Post Surgeon, Benicia Barracks, Cal.

Female. Proboscis moderate, subcylindrical, uniform, the label! ge conically 

 tapered; vestiture black with many dull white scales intermixed which pre- 

 dominate broadly along the central portion without forming a defined band; 

 setae minute, black, those on the labellse more prominently outstanding. Palpi 

 short, about one-fifth as long as the proboscis; vestiture of black scales with a 

 few white ones intermixed, especially at the tips and at the segmentations ; setse 

 moderate, black. Antennre moderate, the joints subequal, rugose, black, pilose ; 

 tori Bubspherical, with a cup-shaped apical excavation, yellowish, dark on inner 

 side, with a patch of small yellowish-white scales; second joint stouter than the 

 others, yellowish at base; hairs of whorls sparse, moderate, black. Clypeus 

 roundedly conical, convex, blackish with a white pruinosity, nude. Eyes black. 

 Occiput black, broadly clothed with rather broad curved scales, dull whitish 

 medianly and slightly tinged with brownish toward the sides, with many slender,
