234 HAUSTELLATA. LEPIDOPTERA. 



The insects of this genus may be distinguished with facility from 

 all the other genera of Geometridse, excepting Triphosa, which 

 has the margins of the wings deeply indented, by the glossiness of 

 the anterior wings, which are rather long and narrow, with their 

 hinder margins very obsoletely waved, the disc traversed by a 

 fascia, more or less solid, and the apex with a dark oblique streak : 

 the antennae of the males are stout, and rather strongly ciliated, 

 and of the females obscurely serrated : all the species are appa- 

 rently double-brooded, appearing early in the spring, and again 

 towards the middle of summer. 



Sp. 1. suffumata. Alis anticis cinereis subnebulosis, nitidis, hasi fascidtjue medio 



piceo-hrunneis. (Exp. alar. 1 unc. 2 — 3 lin.)

Anterior wings very glossy, cinereous clouded with fuscous, with the base pitchy- 

 brown, a broad fascia of the same in the middle, irregularly dentate within, 

 and subtrilobate without, the central lobe most produced and somewhat bifid . 

 towards the apex of the hinder margin is a large fuscous patch edged with 

 white within, the latter colour springing from the apex, and on the costa 

 near the latter a striga of white lunules arises and passes through the fuscous 

 spot to the anal angle of the wings : posterior wings fuscescent, the margin 

 darker, with some undulated pale lines, and the extreme margin of all the 

 wings with a series of geminated black dots 3 cilia cinereous, with fuscous 

 clouds. 



Rather scarce : I have twice taken it in July at Hertford, and 

 Mr. Haworth states that it is found in the beginning of April.

Sp. 2. piceata. Alis anticis lucidis, brunneo-piceis faseid medio saturatiore extus 

 lobatd, margins externa striga albd interrwptd, posticis fuscis Jimbrid satura- 

 tiore. (Exp. alar. 1 unc. 4 lin.) 



La. piceata viihi. 



Anterior wings very glossy; of a deep uniform pitchy-brown, witb a deeper broad 

 central fascia in which is a black spot; its outer margin is lobate, with the 

 central lobe obtuse and entire ; towards the apex of the wing is an interrupted 

 striga composed of white spots, and at the apex is an oblique white streak ; 

 cilia plain pitchy-brown, with obscure darker clouds : posterior wings fuscous, 

 with a darker margin : cilia fuscous.
