Thinophilus pectinifer n. sp. 



Male. Length 5.5 mm.; length of wing 5 mm. Proboscis greatly 

 swollen, dark colored, covered with a thick layer of gray dust; palpi very 

 large, flat, of a clear yellow color, with a very delicate layer of silvery 

 dust, and with several prominent black hairs scattered over their surfaces. 

 Face short and broad, its lower border far above the lower edge of the 

 eyes; widening somewhat below; with two transverse wrinkle-like swel- 

 lings, one near its middle, the other near its lower border; ground color 

 greenish coppery, covered thickly with tawny dust; antennae small, yel- 

 low, the broadly rounded end of the third joint somewhat brownish; 

 arista black; eyes with the white pubescence particularly distinct on their 

 lower portions; cilia of the inferior orbit long and rather dense, yellowish 

 white; front and thorax greenish coppery, covered with a thick layer of 

 rich tawny dust; the thorax with two opaque gray lines down its middle; 

 pleurae covered with a dense layer of tawny dust; scutellum coppery, 

 somewhat brighter than the thorax. Abdomen with six apparent seg- 

 ments; the first distinctly shorter than the second; the second to sixth 

 subequal; all the segments metallic green with coppery reflection and 

 gray dust, thickest on the sides; whole upper surfaces of abdomen beset 

 rather uniformly with short black hairs; hypopygium black, its embedded 

 base covered with whitish dust; lamellae directed forward, of uniform 

 thickness, shining black, without dust and with a few weak hairs at their 

 anterior ends; fore coxae yellow, scarcely infuscated at their extreme bases, 

 with some prominent black hairs on their anterior faces; middle and hind 

 coxae dark, with white dust and yellow tips. Legs yellow, with black 

 huirs; the short tarsal joints individually blackened at their distal ends; 

 fore tibiae with an uninterrupted series of black spines along the whole 

 inner face, three prominent black spines at their distal ends and three 

 smaller and equidistant bristles on the middle of their outer faces; first 

 joint of the fore tarsi with a plantar concavity near its proximal end, where 

 there is also a dense cluster of short black spines; extending from the 

 concavity to the distal end of the joint is an uninterrupted series of short 

 stout spines, which gradually increase in length; these spines are inserted 

 at right angles to the long axis of the joint like the teeth of a comb; mid- 

 dle and hind tarsi plain, the latter with the basal joint only one and one- 

 third times as long as the succeeding joint. Wings of uniform breadth 

 and with prominent anal angle; distinctly yellow along the costal region, 

 more grayish towards the apex and posterior margin ; veins near the costa 

 yellow, elsewhere brown. The posterior cross-vein, which is twice its 

 length from the posterior margin, is covered with a dark gray or blackish 

 cloud, and there is a distinct spot of the same color on the middle of the 

 apical segment of the fourth vein; this vein shows a very faint curvature.
