GEOMETRIDiE. GEOMETRA. 167 



strigse is an obsolete lunular fuscous mark : the posterior wings have the hinder 

 margin darker, and an obscure transverse central striga. Female with the 

 wings paler, the anterior with two strigae as in the male ; the posterior with the 

 hinder margin darkest, and a faint transverse striga. 



Extremely variable : in some examples, though rarely, the base and apex of the 

 anterior wing, anterior to the first, and behind the second, striga, are some- 

 times deep fuscous ; at others merely clouded with the same, but the strigse 

 are generally subparallel .-—the tint of colour also varies. 



Caterpillar reddish-brown, greenish beneath, with black spots and white dots, 

 the tubercles dusky, with their tips greenish : head and anterior legs yellow : — 

 it feeds on the oak, lime, elm, &c. : — the pupa is pale green, with the abdomen 

 yellow. 



Very common throughout the metropolitan district in August 

 and the beginning of September.

Ge. Carpiniaria. HUbner.—Steph. Catal. part ii. p. 119. N'o. 6467. 



Anterior wings pale fulvous, with two transverse fuscescent strigae, and an ob- 

 solete lunular spot between, the space from the hinder striga obscurely tinted 

 with fuscous : posterior wings in both sexes fuscescent. 



Rare : found, towards the end of August and the beginning of 

 September, in woods and shrubby places within the metropolitan 

 district. 



Sp. 10. fuscantaria. Alis anticis truncatis cinerascentis fulvis, h strigd secundd 

 J'uscis; post/cis maris semifascis, posticifulvis. (Exp. alar. 1 imc. 4 5 lin.) 



Ge. fuscantaria. Haworth. — Steph. Catal. part ii. p. 119. No. 64.68. 



Anterior wings ashy-fulvous, with two transverse fuscous strigae, the hinder 

 margin from the second striga also fuscous: posterior in the male fuscous 

 from the base to the middle, the remainder fulvous, and in the female 

 entirely fuscous. 



The resemblance between this and the five preceding insects is so close, that 

 Duponchel apparently considers most, if not all, of them as mere variations 

 of one species, theGe. angularia of Hiibner; but as there is not only manifest 

 diversity in the form of the wings, and in some of the above the sexes resemble 

 each other in colour and markings, whereas in others there is considerable 

 disparity between them, I cannot coincide with his opinion, mine being 

 formed from repeated examinations of my series of the insects in question, 

 comprising nearly 100 varieties. 



Also uncommon : found within the metropolitan district, and in 

 Cambridffeshire.
