THE CANADIAN ENTOMOLOGIST. 181 



ON TWO SPECIES OF AGROTIS, ALLIED TO 



A. TRIANGULUM. 



BY AUG. R. GROTE, 



Curatoi- of Articu/ata, Buffalo Soc. of Natural Sciences. 



Among the material submitted to me for determination by Professor 

 Packard, from the Peabody Academy of Science, are specimens from 

 Maine and Massachusetts of two species of Agrotis allied to, but distinct 

 from A. ti'iangulurn. 



Agrotis attcntns. N. sp. 



The eyes are naked. The middle and hind tibiae are armed, but the 

 fore tibiae are without spines ; male antennae simple, bristled and 

 pubescent. Fore wings pulverulent brown, paler over the costal region,. 

 on which the inception of the geminate lines are marked in dark brown. 

 There is a narrow deep brown basal ray extending to the dentate indistinct 

 t. a. line. Disc not suffused with darker brown between the ordinary 

 spots, which are moderate, pale, with fine dark annuli. Orbicular 

 spherical^ complete, not pointed inferiorly, as in tria7igulum. T. p. line 

 with its pale centre alone perceivable, denticulated, notched opposite the 

 cell. The subterminal space is not diiferentiated by any darker tint ; the 

 subterminal line is pale, preceded at costa by a very slightly darker brown 

 shade, not always noticeable, and not at all like the determinate mark of 

 triangulum. Male hind wings almost whitish ; female darker. Thorax 

 and head like fore wings. Beneath the fore wings are brown, with the 

 exterior line indicated ; hind wings with brown costal region, else pale, 

 with faint discal spot and a double subterminal line marked on the costal 

 region. Maine; two specimens ; expanse, 36 m. m. , 



Agrotis peraticntus. N. sp. 



Eyes naked ; fore tibiae unarmed, middle and hind tibiae spinose; 

 male antennae smiple, bristled and pubescent. Color of A. attcntus, but 

 brighter, rosy brown and more like triangulum, on account of the discal 

 field before the orbicular and between the spots being suffused with dark 

 brown shading. Orbicular spherical, pale ; claviform indicated in out- 

 line ; a deep brown shading accompanies the basal dash. Reniform large 

 and wider than in triangulum. Ordinary lines distinct, geminate, dark 

 brown ; t. p. line with its inner line distinct, lunulate ; its outer line lost
