ART. 15^ REVISIOlSr OF SUBFAMILY PLAT YGA3TEPJXAE FOUTS. 125 



carina, which, although prominent and sharp below the raid- 

 die, is obsolescent above; vertex and occiput shagreened, the 

 former with a rougher sculpture, not separated from the latter by a 

 sharp ridge; cheeks subconvex, finely reticulate; antennae finely 

 pubescent; thorox three-fifths as wide as long, slightly higher than 

 wide, shagreened, more coarsely so on the pronotum; notauli com- 

 plete, meeting in a point posteriorly; mesonotum evenly shagreened; 

 median lobe projecting partly over the scutellar fovea, subacute; 

 lateral lobes not so near the scutellum, with a scanty fringe of white 

 hairs extending posteriorly and touching the scutellum; scutellum 

 broad and more or less depressed, wider than long (not counting the 

 length of the spine which is slightly recurved, as long as the rest of 

 the scutellum) ; abdomen not quite as long but approximately as 

 wide as the thorax, obvate, two-thirds as wide as long; second ter- 

 gite as wide as long, without visible sculpture; following segments 

 broadly transverse, polished; wings hyaline, without marginal cilia, 

 extending nearly the length of the abdomen past its apex. Black; 

 antennal club, coxae, femora and hind tibiae, except at base, dark 

 brown or piceous; rest of appendages yellowish-brown. 



Type locality. — Jacksonville, Florida. 



Paratyve locality. — Arlington, Virginia. 



Type.--Csit. No. 25458, U.S.N.M. 



Redescribed from the type specimen. I have been unable to find 

 any Jacksonville specimens marked ''type" in the national collection 

 and have chosen a paratype female from Arlington, Virginia, as 

 lectotype. The male mentioned by Ashmead in the original descrip- 

 tion and figured on plate 12 of his Monograph represents a new 

 species of Lei^tacis. 



12. LEPTACIS HOPKINSI (Crawford and Bradley). 



Dolichotrypes hopkinsi Crawford and Bradley, Proc. Ent. Soc. Wash., vol. 

 13, 1911, p. 124 pi. 8 (female only). 



Female. — Length 4.5 mm. The original description and figure 

 accompanying it make this species easy to identify. The following 

 diagnosis will help in determining the species: Mostly smooth and 

 highly polished. Length of the thorax 0.49 mm.; of the abdomen 

 3.99; of the first segment of the abdomen 0.41 mm.: of the second 

 0.1 mm.; of the third 0.73 mm.; of the fourth 1.43 mm.; of the 

 fifth 0.32 mm. The segments composing the tail are more or less 

 opaque, a condition due to a kind of fine sculpture on them. 



The lengths given above will of course vary within certain limits 

 but the proportions remain fairly constant. 



Male. — The male types for this species are females and represent 

 a new species of Leptacis. See Leptacis hradleyi, new species. 



Type locality. — West Virginia. 



Type.— Cat. No. 13829, U.S.N.M.
