7. Plusia striatella, Grote. 



f, . — A little smaller than contextn,oi tlie same form, external margin of pri- 

 maries seeming straighter, apices less produced. On the fore wings the trans- 

 verse lines are obsolete. The ornamentation reminds one of Leucania, and 

 consists of darker longitudinal streaks on a pinkish ground. Costa, basally, and 

 internal margin throughout its length, narrowly golden. The larger inferior 

 portion of the fore wing below median vein, from the base outwardly, is deep 

 ochreous brown. This dark color is cleanly cut by a narrow golden streak, 

 neatly black margined, which takes the place of the ordinary spots and ex- 

 tends along the sub-median interspace from within basal third to external mar- 

 gin. A second golden shade streak opposite the cell, and here margining 

 superiorly the darker portion of the wing. No dark apical shade as in festucae, 

 Putnami and contexta. The second longitudinal golden streak opposite the 

 cell appears to replace the apical shade in those species ; it differs here by being 

 continuous nearly to the margin, while the darker oblique shadings are absent 

 in striatella. Fringes pink on both wings, with fine basal line. Hind wings 

 fuscous, much as in allied species. Beneath, rosy ; primaries, dusky fuscous 

 centrally ; hind wings with no apparent transverse line. Thorax and head 

 rosy yellow ; collar with lilac edges.

8. Mamestra clavipleua, Grote. 



t, $ . — Eyes hairy ; tibiae all unarmed. Antennae ( i^ ) shortly pectinate, 

 ciliate beneath, the pectinations furnished with longer lateral spinules. Size 

 moderate ; wood or umber brown, the lines indicated by paler included shades ; 

 median spots large, with distinct darker annuli inwardly pale-edged and with 

 diflfuse dark centers, the reniform with a nearly obsolete white streak. Clavi- 

 form large, triangulate, prominent, almost sometimes blackish — the most no- 

 ticeable ornamentation of the wing ; median space rather narrow ; transverse 

 posterior line incepted above reniform from a prominent costal pale mark, 

 dentate on the veins, inwardly lunulate between them; the inward lunulation 

 is extended on cell 2 and the line again outwardly pointed on the subterminal 

 nervure. Veins darkly streaked opposite the points of the t. p. line ; subtermi- 

 nal line pale, tolerably distinct and continued; W-mark obsolete; a distinct 

 dark terminal line regularly interrupted by pale dots at the extremity of the 

 veins where also the dark fringes are undecidedly cut with pale color. Hind 

 wings and abdomen brownish fuscous, concolorous ; basal portion of the sec- 

 ondaries hardly paler and these are without lines ; beneath dusted with pale 

 scales, with faint transverse line and dot. Abdomen with slight dorsal seg- 

 mentary tufts. Thorax with a central tuft behind the collar. 



Expanse, 30 m. m. Habitat, Albany (Lintner. No. 2,288 5 ; No. 

 2,287 ? ). Allied to the European M. Treitschkei.
