476 NORTH AMERICAN NOCTUID.E. 



bicular obsolete, reniform marked by a lunate j'ellow streak apparently 

 forming the outer margin of the spot. Secondaries blackish, with 

 whitish fringes. Beneath, whitish, powdery, with punctiform outer line 

 and distinct discal spots. Head and thorax concolorous with primaries. 

 Expands l.CO inches (40"""). 



Habitat. — Southern California. 



The collar is somewhat produced centrally, there is an obvious, though 

 not prominent thoracic crest, and a truncate tuft on basal segment of ab- 

 domen. The species is, therefore, very near to Perigrapha, but has not 

 the wing form of that genus, and the S antennae are much more shortly 

 pectinated. The side piece of the S genitalia is equal to tip, where the 

 superior angle is somewhat drawn out, and the inferior angle rounded. 

 Clasper corneous, moderately long, slightly curved ; at base is another, 

 smaller hook, closely united to, and apparently forming part of, the 

 larger one. The type, a unique male, is in Mr. Tepper's collection. 



Group ALIA. 



Three of the species of this group have been much confused. Gtiene^ 

 describes alia from North America, and considers it distinct from incerta 

 Hfn. the European species. Later authors consider them identical, and 

 ]\rr. Grote in his last check list makes incerta the species, with alia Gn. 

 and pacifica Harv. as synonyms. As a matter of fiict pacijica is distinct 

 from our Eastern form and incerta and alia are also very well separated 

 by the structure of the $ genitalia. JL?/a has always been considered 

 a very variable species, while as a matter of fact it is one of the most 

 constant, and the difficulty is, that there is a third and exceedingly 

 variable species usually confounded with alia. It is much more common 

 than alia, and I have found specimens in almost every collection I have 

 seen. I have nametl it — 



T. subterminata Smith, sp. iiov. 



Primaries pale yellowish gray, to deep brown red ; varying to e very- 

 possible intermediate shade. Median lines usually very distinct, gemi- 

 nate, rarely sub-obsolete. T. a. line outwardly oblique, waved. T. p» 

 line nearly parallel with outer margin, very eveuj included space paler, 

 outer line punctiform. S. t. line always very distinct, i)ale, outwardly 

 shaded with some darker color than rest of wing — in dark specimens 

 with black. Claviform large, concolorous, more or less completely out- 

 lined, always traceable. Ordinary spots large, pale ringed, usually 

 concolorous, sometimes paler, rarely darker than ground color. An up- 

 right, dark shade crosses the median space, beyond which the wing is 

 usually darker to t. p. line. Secondaries as variable in shade as the 

 ])rimaries. Beneath pale, ])owdery, with heavy, dark outer line, and 

 large discal spot on all wings. Head and thorax concolorous with pri- 

 maries. Exi)ands 1.4-1. G inches (3o-40™"').
