GENUS STEGOMYIA 379 



13. STEGOMYIA (?) SIGNIFER (Goquillett). 



(Canadian Eut. xxviii, p. 43.) 



Habitat. — Columbia (British North America). 



Time of capture. — June. 



"Evidently very similar to C. fasciatits, Fabr., but differs in having 

 imtoothed ungues in the $ , and, according to Goquillett, by the silvery 

 lateral stripes not being so curved, and it has the pale tarsal bands on 

 the articulations, each involvmg two joints." 



14. STEGOMYIA PSEUDOT^NIATA (Giles). 



Jour. Bombay Nat. Hist. Soc. xiii, p. 607. 



Plate xiv, fig. 8, Venation of wing ; 9, Decoration of body ; 

 10, Larva ? 7. 



Veins of wings densely clothed with long and rather wide 

 scales, the costa having a long white basal patch. Tarsi black, 

 banded white on the upper articulations, one ring on the fore, two 

 on the mid and three on the hind foot, the bases of the first joints 

 being also white, but not involving the tibiae. Thorax black, 

 elaborately decorated with fine white lines (as in figure). Abdo- 

 men black, with narrrow basal snowy bands, barely visible on the 

 hinder segments. Proboscis black, unhanded. 



Head black, with two fine lines in the middle and two broader pairs 

 at the sides, as well as narrow white orbits, but the clypeus is black. 

 Palpi of 5 black, with the apex and a single indistinct band white ; 

 those of (?, almost exactly as in 8. Marsliallii. A small white patch at 

 the roots of the wings ; scutellum with a small median patch of white 

 scales on its anterior border ; pleurae black with short stripes of white 

 scales. Halteres yellowish, with dark knobs. Legs black with longitu- 

 dinal white fines on the femora. Length. — 4"8 mm. 5 '■> 31 mm. ^ . 



Habitat.— The lower Himalayas, Naini Tal and Bakloh, 7,000 ft. The 

 larvae are 8 mm., very dark tinted, so that the eyes can hardly be made 

 out. I found them in a small collection of clean rain water, with some 

 green confervce in the cemented gutter round a house. The respiratory 

 syphon is very short. 



15. STEGOMYIA (?) TARSALIS (Goquillett). 



(Canadian Ent. xxviii, p. 44.) 



Wings unspotted ; tarsi dark, with broad white bands on the 

 articulations. Thorax black, with a dorsal spot and lateral 

 undulating white lines. Abdomen black, with basal white bands.
