48. Thyris usitata, n. sp. (no. 252). 



Dark purplish brown, with cupreous reflections : wings 

 spotted with golden yellow, most of the spots forming a sub- 

 marginal series ; primaries with two unequal and nearly 

 central hyaline white spots, the larger one in front of the 

 smaller ; secondaries with a broad, irregular, hyaline, white 

 belt upon the basal half, but not reaching the costal margin : 

 head, collar, and palpi golden yellow at the sides ; tegulee 

 edged internally with yellow ; a snow-white spot on the 

 shoulder ; abdomen crossed by two slender white bands. 

 Wings below nearly as above, the yellow spots larger and 

 more numerous : venter crossed by two broad white belts. 

 Expanse of wings 8£ lines. 



The above description is taken from specimens obtained by 

 Mr. Jonas. I delayed describing the species as I not only 

 felt doubtful as to its correct location, but was uncertain as to 

 the constancy of the characters distinguishing it from T. 

 fenestrella of Europe. I now feel satisfied that it is distinct, 

 having seen additional examples ; and I have little doubt that 

 its natural position is amongst the Noctuites, in the neigh- 

 bourhood of Penicillaria. 



49. Penicillaria costalis, n. sp. (no. 750). 



Primaries purplish brown, the costal border, basal half of 

 cell, median vein, and a V-shaped marking at the end of the 

 cell (enclosing two dark brown lines) pale buff, two slender 

 irregular black lines with dull castaneous borders indicating 

 the central band ; a reddish and black dash at base ; a diffused 

 castaneous nebula near the external angle, crossed by a submar- 

 ginal series of >-shaped black markings; a whitish undulated 

 marginal line : secondaries smoky brown, the discocellulars 

 and marginal line dusky ; a whitish line at the base of the 

 fringe : body dark brown ; the head, collar, and sides pinky 

 buff. Under surface yellowish ; a brownish diffused apical 

 patch : secondaries with a blackish discocellular spot ; two 

 indistinct brown discal lines. Expanse of wings 1 inch 

 6 lines. 



Plusiidae. 

 50. Plusia pyro]>ia, n. sp. (no. 795). 



Primaries above fuliginous brown, with the central and 

 externo-apical areas fiery cupreous; two widely separated, 

 almost parallel, oblique, dark brown lines (the inner one
