194 JOHN B. SMITH. 



Hab. — Los Angeles Count)', California, in May. 



Three male examples are now before me, two taken by myself 

 and one by Mr. Coquillett. The latter' is from National Museum 

 material in which the species is represented by additional specimens. 

 The characters differentiating the species have been already com- 

 mented upon. 



Hadena tonsa Grt., Can. Ent„ xii, 214, 1880. 



This species I saw in the British Museum in 1891, and it was at 

 that time unknown to me. Examples came to hand in 1898, but 1 

 failed to recognize them and redescribed the species as Hadenella 

 subjuncta in the Can. Ent., xxx, 323. A re examination of the 

 type of tonsa in 1890 suggested the above synonymy which was con- 

 firmed by a comparison of my material later. Mr. Grote's example 

 came from Nevada ; the material at present in my collection is from 

 Washington and Calgary ; I believe I have seen examples also from 

 Colorado, but have seen no eastern examples. 



In Dr. Dyar's Catalogue, Bull. U. S. Nat. Mus., No. 52,. p. 108, 

 minuscula Morr. is placed in Hadenella, with subjuncta as a syno- 

 nym. Orthosia minuscula Morr., referred to Parastichitis by Mr. 

 Grote and later to Hadena by myself, has absolutely nothing in 

 common with tonsa (subjuncta') ; not even wing-form. It does not 

 belong to Hadenella, is a medium sized, broad winged, red brown 

 species, with very simple maculation, and belongs to the fauna of 

 the North Atlantic States. The type is in the Tepper collection, 

 and I have recently seen the species in the Mus. Comp. Zool., from 

 the Thaxter collection. 



Hadena exhausta n. sp. — Ground color a pale creamy gray, varying a 

 little toward a brownish shading. Head with a black or brown line across the 

 front, and another on the vertex. Collar with a black or brown transverse me- 

 dian line. Thoracic vestiture brown tipped. Primaries with the broad basal 

 space gray; the median space which narrows greatly toward the inner margin is 

 brownish or blackish, varying in shade but not striking in contrast; the s. t. 

 space is gray, interrupted in the submedian interspace by a black shade line 

 which continues from a black shade connecting the median lines to the outer 

 margin above the hind angle. Terminal space variably dark shaded. Basal line 

 geminate, obvious only across the costal area. T. a. line well removed fron base, 

 geminate; inner line marked on costa and traceable part way across the wing by 

 brown scales; outer line slender, black ; included space whitish, or at least paler 

 gray ; as a whole the line is obliquely outcurved or almost evenly oblique to the 

 internal vein, reaching the inner margin only a little within the middle. T. p. 

 line geminate, the component lines widely separated, included space whitish or
