304 AUG. R. GROTE. 



verse posterior line. It is irregular, single, wavy and more are less 

 indistinct in the first seven species I have hitherto described; two of 

 which are referred by me with some hesitation to the genus, but I 

 hesitate merely because I do not know the males. In the second 

 group the transverse posterior line is double or has a succeeding pale 

 shade; it is even, distinct and roundedly bent much as is usual in the 

 family. I find, however, that I have been wrong in assigning two 

 species to this group. As yet it only contains a single one which must 

 retain the name of Renia Belfragei, since the differences on whioh I 

 founded a description of R. pastoralis, are caused by the faded con- 

 dition of the specimens. The description under the latter name must 

 be erased, although it stands first, because it does not apply to speci- 

 mens of the species in perfect condition. I have specimens of R. Bel- 

 fragei bcfure me from Pennsylvania and Texas, and have taken the 

 species myself in Alabama. 



PIIALAENOPHAM, Grote. 

 A geometriform genus, slight bodied, with frail ample wings and 

 long recurved labial palpi. Anterior wings straight along costa, tips 

 depressed, with full external margin ; 12-veined ; no accessory cell ; 

 3, 4, 5, approximate and nearly equidistant at base, 5 attached ; cell 

 open; 8 to costa just before tip; 9 out of 8 to costa; 10 out of 8 to 

 costa midway between the origin of 7 (thrown off below) and 9 (thrown 

 off above) ; 6 thrown off below a little within 7. Hind wings rounded 

 8 veined; 5 weak nearly independant, thrown off from a weak crass 

 vein much within the origin of 3 and 4 which spring together from 

 the extremity of the nervure; cell open. Antennae short, simple in 

 the female, the joints provided with very fine bristles in the male. 

 Labial palpi thrown arcuatedly backwards above the head, free, nearly 

 attaining the thorax; basal joints porrected, ascendiug ; third joint 

 reflexed; in the male more thickly scaled. I do not detect ocelli. 

 Eyes rather large; head somewhat restricted behind. Maxillae rather 

 short and weak. Thorax narrow; abdomen linear, not tufted, as long- 

 as internal margin of hind wings. Legs closely scaled ; male fore legs 

 shorter, fore tibiae a little thickened and outwardly thickly scaled ; 

 middle tibiae with terminal and hind tibiae with two pair of spurs. 

 In ornamentation the insect resembles the Geometridae quite strongly.
