Conicera. 179 



joint is elongated, globose at base, but drawn out into a long apex; 

 in the female the third joint short, roiindish; arista apical, shorter 

 or longer, and very short or more distinctly piibescent. Clypeus some- 

 what large, largest in the female and in this sex very large and protrud- 

 ing. Jowls present and a little descending below the eyes; one long 

 lower postocular bristle and, at all events generally, one oral and one 

 genal bristle, both a little smaller; Becker (1901) says: "Backen- und 

 Wangenborsten fehlen", he must have overlooked these bristles. 

 Thorax with one pair of dorsocentral bristles. Scutellum with two 

 bristles. Mesopleura bare. Abdomen is not long, conical, second and 

 sixth segments somewhat elongated (sixtli segment shows generally 

 a transverse furrow so that it looks as if there were seven abdominal 

 segments). Hypopygium somewhat large, higher than long, bent in 

 under abdomen; it is of a similar construction as in Hypocera, it is 

 symmetricai, the opening for the anal tube does not lie between the 

 side prolongations from the tergite, but pierces the tergite; here as 

 in Hjjpocera I think, however, that the uniting below the opening is 

 a secondary one; below the opening the hypopygium is on each side 

 prolonged into a pointed or rounded arm, so that a kind of forceps 

 is formed; the anal tube is small and not protruding. Abdomen in the 

 female has also second and sixth segments somewhat elongated, and 

 it bears at the end two small lamellæ. Abdomen has so short hairs 

 that it appears nearly nude. Legs not robust; in the American species 

 Kerteszii the second and third joints on front tarsi are dilated; front 

 tibiæ with a small dorsal bristle near the base, middle tibiæ with a 

 a dorsal and an anterior bristle forming a pair near the base and an 

 anterior bristle above the apex (foreign species may have four bristles 

 on middle tibiæ {Aldrichi Brues), hind tibiæ likewise with a pair of 

 bristles near the base, a dorsal bristle at about the lower third and a 

 small anterior bristle at apex ; middle tibiæ with one, hind tibiæ with 

 two apical spurs; for the rest the legs are clothed with short hairs, 

 a little longer on the dorsal side of middle tibiæ below the middle; 

 in dauci the dorsal hairs on front tibiæ form a row of small, but distinct 

 bristles; as usual the hairs on the apical part of the posterior side 

 of hind tibiæ are arranged in comb-like transverse rows, and likewise 

 on the posteroventral side of hind metatarsi, and a similar arrange- 

 ment is present on the anterodorsal side of the apical part of middle 

 tibiæ as in Hijpocera, but less distinct. Claws and pulvilli normal, 

 empodium bristle-shaped. Wings with costa short and the costal 

 cilia short; first vein rather curved, mediastinal vein incomplete, not
