REVISION OF SnCCIKS OF TIIH GENUS AGKOTIS. 155 



(lian lines geminate. T. a. line nearly upri;;lit, roiindedly an;;iiliite be- 

 tween veins. T. p. line parallel with onter margin, soniL-wliat paler. S. 

 t. line very indefinitely marked by the darter terminal space, sometimes 

 entirely obsolete. Claviform wanting, or but faintly marked. Orbicu- 

 lar concolorons, round, narrowly delined. lienitorm large, dusky, 

 slightly constricted at middle and marked by a slightly paler aunu- 

 lus. Secondaries, whitish to yellowish fuscous. Beneath powdery, 

 with somewhat darker discal spots. Head and thorax coucolorous. 



ICxpands 10-4i""" ; 1.00-1.75 inches. 



Habitat. — Texas and Arizona. 



A large species, ]U)t ditlicult of recognition, though variable in color. 

 The wings are rather large, the outer margin oblique. The species has 

 been doubtfully referred as synonymous with scgctnm, with which it has 

 little indeed in common. Segetum is a very distinct species allied in 

 markings to messoria, the antenna, however, very distinctly bipectinate, 

 according to my arrangement close to ypsilon. I have seen no Ameri- 

 can specimens of segetuni, and do not believe that such exist.

Red brown, the transverse maculation obsolete. Median lines indi- 

 cated by geminate spots on the costa. S. t. line pale, narrow, irregular, 

 sometimes only niarked by the somewhat darker terminal space. Ordi- 

 nary spots normal in size and shape, pale ringed, blackish. Se(!onda- 

 ries, fusco-luteous, paler toward base ; the veins and a discal lunule 

 darker. Beneath, powdered with reddish and black, all wings with an 

 evident discal spot. Head and thorax concolorous.

Very readily distinguislu'd by the brown color, the darker ordinary 

 spots and obsolete transverse lines. Except in the depth of grouud- 

 color I have noted no appreciable variation.

Lemon yellow, terminal space and anteapioal costal patch dusky, 

 fuscous or brownish. Transverse lines variably distinct, geminate. T. 

 a. line obli(|ue, curved between veins. T. p. line about even with outer 

 margin, slightly lunate between veins. S. t. line very irregular, limit- 

 ing tiie dark ttMininal space. A row of small terminal dots. Claviform 

 wanting. Orbicular dusky indefinite, more or less completely obsolete. 

 Keniform large, dusky, indefinite, but tending to become inferiorly
