CROCIGRAPHA Grt. 



Cau. Ent., 7, 57, 1875. 



Eyes hairy, tibiae unarmed. Vestiture hairy, with few scales inter- 

 mixed. Thorax with an inconspicuous divided crest. Abdomen un- 

 tufted. Primaries elongate, subequal, the hind angle strongly retracted. 

 Habitus of Twniocam/pa geuuina, from which it differs principally by 

 the retracted hind angle of primaries and the more or less evident 

 divided thoracic crest. The male antennae are simple. 



The single species belonging to this genus can be immediately recog- 

 nized by the wing shape and the pale median lines. The harpes of the 

 male are subequal, the tip oblique and fringed with spines. The clasper 

 is rather short curved, hook like, tapering to an acute point. This 

 genus is very unsatisfactorily separated from the typical genus Twnio- 

 campa, but where the characters for generic separation are so scarce? 

 even those which elsewhere would not be recognized must be used to 

 prevent unwieldy assemblages of species. Especially is that necessary 

 in this group of hairy-eyed genera. 



Crocigrapha normani Grt. 



C. E., 1874,6,115 (Perigrapha^ ; Morr., C. E., 1874,6,251 {Tamiocampa) ; Grt., id., 

 1875, 7, 57 (Crocigrapha) ; id., 1875, 7, 227, pi. 1, f. 13. 



Varies from reddish luteous to rather deep red brown, always more 

 or less powdery; the superior portiou of median space often darker, 

 especially between the ordinary spots. Median lines geminate, even, 

 the included space pale, bluish gray; the defining lines not much 

 darker than ground color. T. a. line evenly and slightly outwardly 

 oblique. T. p. line curved over reniform, then strongly incurved, 

 nearly parallel with the outer margin. S. t. line obsolete, or defined 

 only by the slightly darker terminal space. In dark specimens the 

 apex is pale and the line is marked at that point. Stigmata large, con- 

 colorous, reniform interiorly black marked; outlined by pale scales; 

 orbicular often obsolete. Secondaries soiled, whitish, outwardly darker. 

 Beneath pale, with more or less evident punctiform outer line and a 

 discal dot on secondaries. Head and thorax coneolorous, with prima- 

 ries. Expands 1.30 to 1.G0 inches (33 to 40 mm ). 



Habitat. — New England and Middle States. 



The genitalia are described in the description of the genus, and there 

 is nothing to add to the remarks there made. 



ORTHODES Gn. 



Noct. I, 371. Morr. Can. Ent., 6, 251 (list and char.). 



Eyes hairy, tibia? unarmed. Thorax without tufts, or with only an 

 indefinite anterior crest and posterior bunch of loose hair. Abdomen 

 untufted. Primaries short, broad, with rectangular or obtuse apices, 

 and rounded or nearly straight outer margin. Frontal vestiture rather
