By a. R. Grote, a. M. 



Thyatira Lorata, n. s. 



Forewings ashen brown, shaded with white over median 

 space, superiorly and about a deep brown triangular shaded 

 blotch, which marks the inception on costa of the subterminal 

 line. A basal white median patch, edged with black and stained 

 with pink. Median lines distinct, black, single, approximate, 

 approaching inferiorly; t. p. line followed by black venular 

 marks. Stigmata small, near together; reniform upright, sub- 

 ovate : orbicular, round. A reddish patch at internal angle, edged 

 within with white. A narrow waved apical streak. Hind-wings 

 yellowish fuscous, with sinuate mesial shade and reddish fringes. 

 Thorax light brown ; sides of tegulae whitish ; beneath dull yel- 

 lowish fuscous with double sinuate shade bands emanating from 

 two costal dark brown or blackish marks on fore-wings. Head 

 and collar deep brown.

At once distinguished from our Eastern Pudens by the 

 broader primaries, with their black propinquitous median lines, 

 the absence of the apical patch and the subterminal dark costal 

 blotch, while the costal region at base is equally dark, the stig- 

 mata complete ; the reniform a little reddish ; the basal patch is 

 notched superiorly and less extended than in Piidens. 



Bombycia Semicircularis, n. s. 



? . Eyes naked ; head sunken ; a tuft on the third abdominal 

 segment ; wings broad. • Primaries with a basal creamy patch ; 

 black edged, pointed on the s. m. fold. Beyond is a broad trans- 

 verse anterior shaded band, made up of three or four black lines 

 with the spaces between them black-shaded. The ground color 

 of the wing is hoary gray. A second vague black band, made up of 

 two or three lines, crosses the wing beyond the disc and approaches 

 the first on submedian fold. Median space dark gray ; stigmata 

 approximate, not very noticeable, concolorous, the reniform with 

 blackish centre ; the orbicular reduced, round. A black festooned 

 line below apices inaugurates the s. t. line, somewhat as in TJiya- 

 tira Lorata, but the first curve is obsolete, the line appearing 

 along external margin below the tip ; it is discontinued below 

 vein 6. Hind wings yellowish gray, with an inner broad and 

 dififuse band, beyond which the wing is narrowly paler before an 

 indistict outer line. Beneath yellowish gray with double bands, 

 the inner very broad ; tegulae whitish with brown tips ; head and 

 collar dark.

This specimen is more sombre than B. Improvisa, Hy. Edw., 

 and wants the "yellowish green patches and rosy markings.
