upright, sinuate, not reaching costa ; iucludecl space wliitish. T .p. line 

 hmulate, iuternipted, single; sharply detining the paler s. t. space, its 

 course inwardly oblique even, hardly curved over cell. S. t. line not 

 defined ; marked only by the contrast in color between terminal and s. t. 

 space. This outline is very irregular; the terminal shade sends in a 

 broad angulation opposite the cell, is much narrowed on veins 3 and 4^ 

 and again broader to hind margin. Claviform concolorons, narrowly 

 outlined in black, short and rather broad. Ordinary spots well defined, 

 narrowly annulate with white, centered with pale yellowish. Orbicular 

 irregularly ovate ; reniform normal. Secondaries yellowish fuscous. 

 Beneath white, powdery: primaries with disk smoky; all wings with 

 dusky discal luuule. Head and thorax concolorous ; collar iuferiorly 

 whitish yellow. 



Expands 37-44'"™ ; 1.5-1.75 inches. 



Habitat. — California. 



A pretty and well defined species with no peculiarities, not already 

 enumerated ; it varies from luteous to brightred brown, the latter being 

 typical of spccialis. Mr. Edwards' collection shows both forms. The 

 anteunal difference noted by Mr. Grote exists in terms only. Wilsonii 

 equally has " tufts of bristles on the joints" and at the same time both 

 forms have them " brush like." 



The U. S. Museum collection contains a very pretty series of this 

 species showing the very wide range of variation in ground color. 

 Scarcely two specimens are entirely alike, and yet the characteristic 

 appearance of the species is so marked that no mistake is possible in 

 its recognition. 



Carneades lacunosa Grt. 



1878. Grt., Bull. Geol. Siirv., iv, 7"2, Agrotis. 



Fuso luteous, sordid ; cell darker, shaded with blackish, costa very 

 slightly paler. A darker longitudinal basal shade crossed by the nar- 

 row basal line and limited outwardly by the t. a. line. This latter as 

 in wilsonii, but less distinct. T. p. line very faintly indicated, obso- 

 letely geminate; its course as in wilsonii. S. t. line distinct narrow, 

 ]>ale, limiting the somewhat darker terminal space ; preceded by a row 

 of sagittate black spots, its course sinuate, not greatly divergent at any 

 part of its course. Ordinary spots essentially as in ivilsonii, but not so 

 contrasting, the center being almost concolorous. Secondaries and 

 underside as in wilsonii. 



Expands 35-39""" ; 1.40-1.50 inches. 



Habitat. — California. 



With essentially the same maculation this species is yet very distinct 

 from ivilsonii by the obsolete t. p. line and well marked s. t. line. The 

 collar is concolorons, but is crossed by a dark line. The species is cred- 

 ited to Mr. Morrison in lists, but I can not find that he ever described it. 

 Mr. Grote's description above cited is the first appearance of the 

 species in literature so far as I know, and he should be credited with it.
