Original Desckiption of Cuxex bestuans: 



Thorax bright chestnut-brown, with golden-brown curved scales and two round 

 pale spots on the mesonotum and a patch of pale scales just in front of the root of the 

 wings, and paler scales around the bare space in front of the scutellum. Abdomen 

 dusky brown, with basal bands of yellow and pure-white lateral spots. Legs bronzy- 

 brown to black, except coxae, bases and venter of femora, which are very pale, and 

 also a yellow knee spot. Ungues of $ equal and simple. 



$. Head black, with numerous pale creamy curved scales and black upright 

 forked ones, with flat white scales at the sides of the head; palpi black, greyish at 

 the tip; antennae with the basal joint and base of the second joint testaceous, re- 

 mainder blackish-brown, with pale pubescence; clypeus and proboscis brown. 



Thorax bright chestnut-brown, with short bright golden-brown curved scales and 

 two round spots on the mesonotum of pale creamy scales, the bare patch in front of 

 the scutellum surrounded by almost white scales, and another patch on each side 

 just in front of the wing roots, three rows of black bristles, the median one ending 

 in front of the bare patch in front of the scutellum; scutellum pale; metanotum 

 ochraceous-brown; pleurae pale testaceous, with four patches of white scales. 



Abdomen ochraceous, covered with dusky-brown scales, the bases of the segments 

 having a band of creamy-yellow scales, with a pure-white spot on each side of the 

 segments; first segment ochraceous, with two median tufts of blackish scales and long 

 golden hairs; second segment with the white scales forming a median line half 

 across the segment; the abdomen densely clothed laterally with pale golden hairs. 



Legs with the coxae, bases, and under-sides of the femora almost white, remainder 

 deep bronzy-brown to almost black, there being, however, a very distinct yellowish 

 knee spot; claws equal and simple. 



Wings almost exactly as in C. pipiens. Halteres with pale ochraceous stem and 

 fuscous knob. 



Length. 6 mm. 



Habitat. Toronto, Ontario, Canada (E. M. Walker) (66). 



Time of capture. June. 



Observations. Very closely related to C. pipiens, but I think distinct. It differs 

 in the basal banding of the abdomen being uniform, and not curved; in the presence 

 of very plain white lateral spots; in the yellower tinge of the whole body, and espe- 

 cially in the deep golden-brown thoracic scales and paler ornamentation. 



A single $ only received, taken on a window-pane. 



I do not know if Walker described this species; I can find no record of it. A 

 specimen is so named in the old Museum collection by Walker, and, as it is certainly 

 distinct, and a fresh specimen has come to hand, I retain his name.

Female. Proboscis rather slender, uniform, labellge conically tapered, brown ; 

 vestiture of brown scales ; palpi short, one-fifth as long as proboscis, slender, dark 

 brown, with a few outstanding setae. Antennae with joints subequal, rugose, 

 pilose, black, second joint pale at base; tori subspherical with a cup-shaped 

 apical excavation, luteous, black within ; hairs of whorls sparse, moderate, black. 

 Clypeus rounded triangular, doubly excavated at base, dark brown, nude. Occi- 

 put brown, clothed with narrow, curved yellowish-white scales, a brown patch 

 each side of middle, of dark suberect scales, flat white scales well down the sides, 

 margin of eyes white scaled, many erect, forked black scales on vertex ; a row of 

 bristles along ocular margins. 



Prothoracic lobes elliptical, remote dorsally, clothed with broad white scales 

 and brown bristles. Mesonotum reddish brown with two impressed bare lines;
