the anterior cross-vein with the stem of the forked vein behind, some- 

 what as in Liponeura, except that the cross-vein joins the fifth vein 

 before the sixth longitudinal branches from it. Legs elongate, the 

 femora somewhat thickened (the hind pair decidedly thickened) before 

 the extremity; ungues large, simple. Eye-facets uniform. 



In Loew's synopsis (op. cit. ) the genus would be located with 

 Liponeura, from which it is at once distinguished by the wide difference 

 in the neuration. Osten Sacken's grouping is a more natural one, yet 

 not wholly satisfactory. The genus is evidently nearest allied to 

 Paltostoma and Hapalothrix; to be distinguished from the former by 

 the short proboscis; from the latter by the spurred hind tibiae; from 

 both by the presence of the posterior connecting vein in the wing. 

 There are no pulvilli, and the empodium is rudimentary. The species 

 is nearly or quite bare, agreeing therein with Paltostoma, and differing 

 from Hapalothrix liigiibris. It gives me pleasure to name this genus 

 in honor of the distinguished entomologist and naturalist. Prof. F. H.

 Snowia rufescens, n. sp. 



Female. Bare. Front black, not shining, reddish below. Face red- 

 dish yellowish. Antennae blackish, the basal joints yellowish. Thorax 

 yellow, opaque; the dorsum orange red. Abdomen deep red, the 

 narrow margins of the segments brownish; venter lighter colored. Legs 

 dark brown or blackish, the basal part of the femora yellowish. Wings 

 nearly hyaline, the anterior veins blackish; the posterior ones lighter 

 colored; furcation of fifth and sixth veins near the base of the wing- 

 nearly opposite the axillary incisure. Length 8 millim.

THE AMERICAN SPECIES OF STYLOCASTER. 



In the November number of the Wiener Entomologische Zeitung, 

 page 216, Mr. V. von Roeder gave a synopsis of the known species of 

 Stylogaster, in which he accepts three only, — 6". stylata Fabr. ; 

 ^. neglecta Will., and 6". leomnn Westwood. S. hiannulata Say, he 

 considers the same as S. stylata, on the strength of Wiedemann's 

 determination. He may be right, but I think not. 



In the Transactions of the Connecticut Academy, vol. vi, p. 92, I 

 gave as my reason for employing Say's, rather than Fabricius' name 

 for the North American species, that Wiedemann had confounded two 

 species in his description, as was evident from the difference in 

 the length of the antennal joints, which Wiedemann erroneously con- 

 sidered a sexual character. Since then I have received a female 

 specimen of a Brazilian species, which enables me to clear up the 

 confusion, so far as Wiedemann is concerned.
