GEOMETRIDiE. ANAITIS. 24-3 



a double arch, within which are some black spots on the hinder margin; cilia 

 white, spotted with brown : posterior wings cinereous, with a faint brownish 

 dot towards the base, and a waved striga behind the middle; cilia ashy, more 

 or less clouded with pale fuscous. Female paler, more clouded. 

 Extremely variable : in some examples the two fasciae on the anterior wino-s 

 are almost united into one, in others the space between is almost v/hite, and 

 the fasciaj are remote. 



Apparently very common in tlie north of England, wlience I 

 have received numerous examples. " Heaths, Prestwick Car." —

Genus CCVII. — Anaitis, DuponcheL 



Palpi long, approximating, porrected obliquely in form of a beak, obtuse, densely 

 clothed with short scales, the terminal joint shghtly visible; triarticulate 

 basal joint curved, rather longer and more robust than the second, which is 

 straight and a little attenuated ; terminal minute, conic: maxilla; loufr. An- 

 tenna; simple in both sexes, shghtly pubescent within in the males: head 

 small;J'ore/ieacZ very prominent: e^e* globose : ^/jorax slender : wings entire 

 forming a triangle during repose; anterior acute, traversed by several angular 

 parallel fasciae, generally divided into bands of three lines each; posterior 

 immaculate : abdomen long and slender, the terminal joint considerably elon- 

 gated, conical in both sexes, shghtly fringed in the males, as weU as the 

 penultimate joint above, rather stouter in the females ; the latter the largest. 

 Larva with 10 legs. 



Anaitis being proposed by Duponchel, and briefly characterized 

 before the imposition of the term Larissa, is here employed to 

 designate the present genus, which differs from the foregoing by 

 the dissimilar structure of the palpi, form and strigation of the wings, 

 which are of a different texture, and by the abdomen : the sexes 

 are similar, and the females larger than the males.

Wings ashy- white; the anterior with an angulated brown striga at the base, 

 broad and unsoUd on the costa, and diminishing to a fine line on the inner 

 margin ; then two fasciae in the middle, composed of three strigae each, and 

 confluent here and there, so as to appear clouded, the former shghtly curved, 

 the second somewhat flexuous and biangulated on the outer edge; adjoining
