SUBFAMILY HYPOPTINAE 



Hyl'optiiiae Neunioegen and Dyar, Jour. N. Y. Ent. Soc, II, p. l6o. (1894) 

 (partim.) 



The type of the genus Hypopta Hbn. (Verz. Bek. Schmett, p. 195, 

 1822) becomes, according to the "first species" principle, ambigita 

 Hbn., a species from S. America. We have had the opportunity of 

 examining a specimen of this insect and find that a cross-vein exists 

 between the anal veins of primaries. On this ground we have re- 

 tained the name Hypoptinac for the group, restricting it merely to 

 those species and genera possessing an anal cross-vein on primaries. 

 All the species at present included under Hypopta must, however, be 

 placed in other genera, as ambigiia shows considerable difference in 

 venation and would fall under Dyar's genus Ravigia, which thus be- 

 comes a synonym of Hypopta. 



Genus Hypopta Hubner. (Type ambigua Hbn.) 



Hypopta Hubner, Verz. Bek. Schmett., p. 195 (1822). 



Ravigia Dyar, Proc. Nat. Mus., XXIX, p. 178 (1906) (type polybinides Schaus). 



Palpi short, projecting somewhat beyond head, porrect, third joint conical ; 

 antennae bipectinate, frons untufted ; hind tibiae with two pairs of spurs ; pri- 

 maries with vein Ri from near areole. R. and Ri from areole, R4 and Rs stalked, 

 from a point with Rj. Mi from below areole, Qh from angle of cell, widely separ- 

 ated from Cu:, 1st anal obsolescent in basal half, connected with 2nd anal by 

 cross vein in outer fourth ; secondaries, veins R and Mi separate and subparallel 

 beyond cell, subcostal cross-bar present or absent, Mj, Ma and Cui close to- 

 gether from near angle of cell ; cellula intrusa present on both wings, frenulum 

 well developed. 



The above description of the venation is froin a drawing kindly 

 made for us by Mr. J. A. Grossbeck, from a specimen of ambigua in 

 Coll. Strecker. We have not seen the type of the genus Ravigia our- 

 selves, but Dr. Dyar has examined the type specimen and compared 

 the venation with our sketch and tells us that they are practically 

 identical.
