Agrotis S])issa Guen., I^oct. 1, 261. 



This greatly resembles Crassa, but the species is smaller (35 mil.), of 

 a grayish-brown testaceous, the veins darker and relieved by a slightly 

 paler ground, especially the median and its last branch; markings like 

 Crassa, but there is a great disproportion between the two stigmata; 

 the t. J), line forms a dash entering below the fourth inferior nervule; 

 and on the inner margin, below the submedian vein, it is elongated in 

 such a way as to touch the top of the mark formed by the extra-basal 

 line; the cuneiform marks of the s. t. line are more regular and more 

 equal; the hind wings are darker and more uniform. 



Am. Sept. Coll. Bdv. Two bad specimens. 



Hoctua ochrogaster Guen. I^oct. 1, 237. 



A little larger than plecta, which it resembles in markings. The red of 

 the primaries is paler, the subterminal is well marked by a deep blackish 

 shade. The terminal dots are rounded and separate; the fringe is cut 

 by a dark line; the stigmata are larger; the reniform less constricted, 

 and the median vein is equally white. The hind wings have a very 

 distinct series of rounded terminal dots. The collar is ochery white, as 

 also the abdomen, which is without any reddish anal tuft. 



Am. Sept. Coll. Bdv. One male. 



Hoctua elimata Guen., Koct. 1, 333. 40 mil. 



Fore wings pale ashen, much mixed with pale violaceous red, all the 

 lines visible, of the former color, ijreceded and separated by shades of 

 the latter tint, especially the subterminal line, which is very sinuous 

 and irregular; the t. p. line is denticulate; the t. a. line forms three 

 large teeth, all marked on costa by a deep brown mark. The two stig- 

 mata Avell defined, pale, separated inferiorly by a dark line; the orbi- 

 cular contiguous to the t. a. line; the reniform large and regular, the 

 terminal space ashen. Hind wings of a uniform dark gray with the 

 fringe paler and more reddish. Beneath the four wings are reddish. 

 Antennae of the male strongly pectinate. Female larger but similar. 

 Georgia. Coll. Doubleday. Caterpillar having nearly the same colors 

 as the moth, that is to say, the dorsal region and subdorsal are reddish, 

 the lateral ashen, without well defined lines, and only showing some 

 slightly darker subdorsal markings. Head ocher yellow. Collar dark 

 brown. Feet concolorous. Abbot represents it on chrysanthemum. 

 Chrysalis light red, with the membrane covering the wings mixed with 

 greenish. 



Agrotis tesselloides n. s. 



This is the Californian representative of tessellata ; of this latter 1 am 

 indebted to Professor Liutner for a series of nine selected specimens 

 showing its range of variation. Six specimens of tesselloides agree 

 among themselves and differ by the paler, more purply gray tint of the
