REVISION OF SPECIES OF THE GENUS AGROTIS. 57 



only distinct, tine, distinctly marked on costa, its course evenl}' ooiiqne. 

 The inferior outer portion of basal si)ace is darker. T. p. line geminate, 

 included space of palo ground color; its course sinuate, widely bent 

 over cell, evenly incurved beneath. S. t. line broad i)ale, very even. 

 Outer portion of s. t. space shaded with pale ground color, else beyond 

 t. p. line darker red brown. Orbicular round, moderate, concolorous ; 

 reniform normal, well sized, somewhat obscured by the broad trans- 

 verse brown shade which occupies the outer third of uiediau space. 

 Claviform very distinct velvety deep brown, forming at once the most 

 striking characteristic of the si)ecies. Secondaries reddish fuscous. 

 Beneath pale, strongly powdered with rust red ; a common outer line 

 and discal si)0t. Thorax concolorous. Head and collar dashed with 

 gray. 



Expands 33-34"""; 1.32-1.36 inches. 



Habitat. — Massachusetts, Maine, White ^lonntains, and northward; 

 Canada; Hudson Bay territory. 



One of the most easily recognizable of the species. There is nothing 

 to conflict with the remarkable deep brown claviform, which forms the 

 most salient feature of the maculation.

Eather pale rust red ; terminal space steel gray ; from the basal space 

 along the costa to t. p. line sprinkled with gray. Transverse lines 

 single, brown; t. a. line interrupted, upright or slightly oblique; t. p. 

 line sinuate, distinct ; s. t. line marked by the contrasting gray terminal 

 space; twice outwardly dentate, then sinuate. Ordinary spots large, 

 irregular, completely pale ringed. Claviform wanting. Secondaries 

 brownish gray with a fuscous discal spot. Beneath powdered reddish 

 gray with discal spot on each wing. 



Expands 34"""; 1.35 inches. 



Habitat. — Labrador, Mount Washington. 



The typo is in the Peabody Museum at Salem, and is badly eaten. 

 The head and prothorax are entirely gone, and the body is a mere shell. 



The wings were (June, 1884) still in good condition. The insect is 

 easily recognized by the gray terminal space and the irregular, pale 

 ringed ordinary sx)ots. The above description was made from the type 

 and I have uever seen another specimen. 



Now in Cambridge at the Museum of Comparative Zoology.
