REVISION OF SPECIES OF THE GENUS AGROTIS. 121) 



space slightly clouded with dusky. Secondaries white. Beueath all 

 winjis with discal lunule, piiiiiai ies dusky. T. p. line faintly ie])ro- 

 dnced. Secondaries wiiite. 



I'jxpands 'M-'SV'""; 1.2r)-l,;)5 inches. 



Habitat. — Illinois, ^Missouri, Kansas, New Mexico. 



A peculiar s[»ecies in many respects; the 5 antenna' are pectinate 

 rather than serrate, the pectinations ciliate. The primaries are rather 

 shorter more obtuse than usual, the fringes of secondaries longer; the 

 front is less roughened than in the other species of the group, and the 

 anterior tibiie are unusually heavily armed at tip. As a whole the 

 Jldiotliid ^pe is very strongly marked in this species and it is not 

 at all impiobable that with sutHcient material at hand its nearest allies 

 will be found to be Anthocia nohilis and pnckardii. The lore tibiae are 

 short and broad and have two heavy claws at inner side of tip and a 

 series of five or six heavy claw-like spines outwardly. The species is 

 left here rather for i)resent convenience than from any conviction that 

 it belongs where placed.

Luteous gray; basal and s. t. spaces paler; all the lines and spots well 

 marked. l>asal line evident, marked with whiteoutwardly ; t. a. line in- 

 wardly bent on costa, straight to vein 1, then outwardly curved to hind 

 margin ; the line marked inwardly with white. T. p. line even or but 

 slightly lunate between veins outwardly marked with white; outwardly 

 curved over cell, and inwardly sinuate to hind margin. S. t. line diy- 

 tinct white, irregular, prominently dentate on veins 3 and 4. All the 

 veins more or less evidently marked with white. Claviform distinct, 

 concolorous outlined in black, reaching to middle of median space. 

 Orbicular large, round, i)aler, centered with darker scales. Keniform 

 large ui)right centered with rather bluish or smoky black" scales. Head 

 and thorax mixed yellow gray. Secondaries blackish, paler at base. 

 Beneath whitish powdered with black ; primaries dusky on disc. 



Expands 01-30""". ; 1.2a-1.45 inches. 



Habitat.— Colorado, Xew Mexico, Nebraska, Arizona, Utah. 



Like the preceding this species has pectinate and cdiate $ antenna?, 

 the pectinations shorter than in rUcyana ; the tibial armature is heavy, 

 and the fringes though shorter than in rUeijana or even doUii are 

 longer than usual in the genus. The 9 fringes are not so long as those 

 of the $ .

Gray, washed with luteous or ocherous the yellow tints most evi- 

 dent in basal and s. t. space. Transverse lines very faint ; chiefly dis- 

 liiuct by the contrast between the slightly darker, less yellow wediaii
