154 THE CANADIAN ENTOMOLOGIST. 



Agrotis citricolor, n. s. 



# $ . All the tibiae spinose ; eyes naked ; $ antennae brush-like. 

 Thorax and fore wings light lemon yellow ; a shaded blackish mark in the 

 place of the reniform. Terminal space and fringes brownish. Lines 

 obsolete. Hind wings and abdomen white. Exp. 34 mil. Hab. Colorado. 



This species is so simply marked and colored that the description is 

 necessarily brief, while the insect is none the less readily recognizable. 



Agrotis innotdbilis Grote, Proc. Ac. N. S. Phil,, 202, 1S74. 



This species may be known by the yellow brown reniform contrasting 

 with the concolorous blackish orbicular. The collar is black above, gray 

 below. Specimens from Washington Territory differ from my type from 

 California by the median space being shaded with brown, the claviform 

 outlined, and several fine black lines cross from the two median lines over 

 the median space inferiorly. The species is allied to bicamea. The 

 orbicular is more or less evidently quadrate and oblique. 



Polia aedon, n. s. 



Eyes naked. Tibiae unarmed. Whitish gray. All the lines well 

 written, single, black, acutely dentate. Orbicular elongate on the cell, 

 complete, rather small. Claviform long ; reniform incompletely limited 

 exteriorly, rather wide, moderate. Median shade nearly continuous, 

 dentate, shading into ochrey, and the reniform is slightly ochrey. Sub- 

 terminal line irregular, strongly dentate, the teeth strongly shaded with 

 black. T p. line continuous, dentate, rather fainter than the other lines. 

 A dotted terminal line ; fringes dotted. The whole insect is rather dark 

 gray ; the thoracic disc with a yellowish tuft behind the collar ; faint lines 

 on the tegulae ; a black line across the face ; palpi entirely gray. Hind 

 wings pale with a mesial line accented on the veins. Beneath pale, the 

 line appears dotted and there are discal marks on both wings. Exp. 40 

 mil. Hab. Nevada, Mr. Neumoegen ; I have seen a second specimen in 

 Mr. Graef's collection. 



Tarache sutrix, n. s. 



Allied to apnea and between aprica and tenuicula. Yellowish or 

 ochrey white. Inner line pale ochrey. A black point for the orbicular. 

 Median shade rather thick, black, below and within the dot or the faint 

 ringlet .which represents the reniform ; above marked in pale ochrey to
