 GEOMETRINA OF NORTH AMERICA. 



BY GEO. D. HULST, BROOKLYN, N. Y. 

 ( Coii/liiiicd fioiii pa^'-e 164.) 

 DiASTICTIS BENIGNA, 11. sp. 



Expands 23 mm. Palpi rather long, heavy, drooping, blue-gray; 

 front, thorax and abdomen blue-gray, the latter whitish lined posteriorly 

 on segments. Fore wings bluish-gray, lightest on middle field, mixed 

 with some black scales; basal line faint or obsolete, marked by a black 

 spot on costa ; middle line beginning with black spot at costa, then 

 through black lengthened discal spot, then obsolete ; outer line with 

 black spot at costa, otherwise obsolete ; outer field darker towards 

 margin, with a large brown submarginal shading between 3 and 5. Hind 

 wings even, smooth, blue-gray. Beneath dark bluish fuscous on all 

 wings, becoming blackish along outer margins ; costa of fore wings 

 speckled with black and gray. 



Los Angeles Co., Cal. Type in National Museum. An insect very 

 much ill appearance like the Eastern Macaria inbiorata, Pack., but the 

 fore wings are not falcate, the hind wings are not angled, and the palpi 

 are much longer and heavier. The antennae of D. bejiigna^ here 

 described, are wanting, so the generic reference cannot be certain ; but 

 as there is no hair pencil on hind tibise in ^ , it cannot be either 

 Sciagraphia or Macaria, as I define them. Type No. 3959. 



DiASTICTIS SERICEATA, U. Sp. 



Expands 24-26 mm. Palpi, front and thorax, white ; abdomen 

 white, with fuscous stain, with many intermixed black scales. Fore wings 

 white, with long light fuscous cross striations, which become many 

 exceedingly fine, yet sharply distinct, though often broken, cross lines, 

 giving an appearance of solid colour to the naked eye ; a black, geminate, 

 straight, basal cross line ; another outward, less distinct, also geminate, 

 nearly straight, with a band of reddish-brown between ; discal spots 

 black. Hind wings light fuscous, becoming grayish outwardly ; marginal 

 line of black spots on all wings. Beneath fuscous gray, coarsely striated 

 with fuscous on hind wings, outer margins darkest. The fore wings have 

 a smooth, silky appearance, with an apparent broad central band, even 

 in width across the wing.
