Arthopeas americana Loew
1861. Arthropeas americana Loew, Berl. Ent. Zeits., v, p. 316.
Front, face and thorax pale pollinose, the mesonotum with three broad dark stripes; legs, antennae and abdomen pale brownish yellow, abdomen concolorous, but tinged with reddish, the 1 8 NORTH AMERICAN RHAGIONIDAE (dIPTERA)
segments broadly banded basally with black; wings grayish or pale brownish with a median band and an irregular area towards base whitish.
Female. — Length, 9 to 10 mm. Head: Front and face apparently black in ground color, but wholly yellowish pollinose and without hairs; the face about twice the width of the ocellar tubercle above, a little wider below; antennae pale brownish yellow, the flagellum tapering towards tip, the last segment several times as long as the others and ending in an acute point; palpi and proboscis also yellowish pollinose, the former with fine pale hairs, the latter showing brownish in places and with a few very fine pale hairs.
Thorax: Mesonotum and scutellum light grayish yellow pollinose, the former with three broad, dark brownish stripes, with rather numerous very fine, very short, pale hairs; pleura apparently pale brownish yellow more or less overlaid by light grayish yellow pollen, bare, except for the proand metapleura which have rather long pale hairs; metanotum mostly hidden on the specimens which I have seen but apparently concolorous with the pleura and bare; halteres pale brownish yellow.
Abdomen: Brownish yellow, sometimes tinged with brick red, first four segments with basal half dark brownish, in some cases this band, especially on the first and second segments may not reach the lateral border, thus tending to form merely a large median spot; sparsely covered above with fine short black hairs which are slightly longer on sides.
Legs: Coxae concolorous with pleura, hairs rather long, pale; rest of legs light brownish yellow, the tarsi but little darkened.
Wings: Membrane distinctly pale brownish or grayish brown somewhat variably marked with whitish as follows: a partial band through the middle comprising all or most of the discal cell and an equal area immediately above it; also usually a spot at the edge of the wing in each of the posterior cells, one at the base of the first basal cell and sometimes an elongate area partly in the first and partly in the second basal cells running nearly the length of each of them ; costal cell tinged with yellowish brown; stigma elongate, dark brown; veins for most part dark brown but some of them yellowish whitish.
