I am not aware that the type of the genus, ©. paradoxa, has 
ever been found, since I discovered numerous speceimens of it in 
Virginia. 
Lipsothrix. 
Loew, Beschr. Eur. Dipt. III, p. 67; 1873. 
Lipsothrix ieterica Egger, Verh. Z. B. Ges. 1863, p. 1105 
(Trichosticha;, Syn. L. errans Wk., according to Verrall, 1. c.) and 
L. nobilis Loew, 1. c. both from central Europe, are the present 
representatives of the genus. To Loew’s characterization must be 
added that Lipsothrix has no empodia, contrary to the great 
majority of the Eriopterina. I noticed this character in a spe- 
cimen which I took in the Pyrendes. Upon my request Prof. Mik 
kindly sent me a magnified drawing of the last tarsal joint of an 
Austrian specimen; it has no empodia and distinetly bidentate claws. 
The genus has very little of the Eriopterina in its general appearance. 
Larva and pupa have been described by Beling, Verh. Zool. Bot. Ges. 
1886, p. 192. 
Sigmatomera. 
OÖ. Sacken, Monographs etc. IV, p. 137, 1869; compare also the 
additions at the end of Vol. II. 
Tibiae without spours, small empodia, wings with four posterior 
cells and, in the male, long, nodose, 16-jointed antennae, not unlike 
those of Nephrotoma, distinguish this genus. The female is as yet 
unknown. The typical species is 8. Hlavipennis from Mexico (Mo- 
nogr. etc. Vol. HI, Additions). 
A second species, S. amazonica Westw., Trans. Ent. Soc. Lond. 
1881, p. 366, Tab. 17, f. 5, from Brazil, has been added since. It 
differs in having an open discal cell and in some other points of minor 
importance. 
Cladura.

the wing is figured 1. ce. p. 34; Tab. 4, f. 22, forceps. 
Two species from North-America have been described. The
