88 THE GENERA OF BRITISH MOTHS. 
amuch duller green than any other of the group, and sometimes greenish-gray. The Caterpillar feeds on common 
Broom, on Heaths or Warrens, and the Moth appears in July. It is found as far north as Ayrshire. 
The genus Luchloris. This genus contains a single British species, separated from Geometra on account of 
the habits of the Caterpillar, which clothes itself with portions of small leaves, seed vessels, scales of flowers, 
or other vegetable fragments, which it binds together so as to form a kind of shell or habitation, which it carries 
about with it somewhat after the manner of the singular larve of the Psychide., The larva otherwise resembles 
in general conformation that of Geometra Papilionaria, which has caused some English authors to place LZ. 
Smaragdaria in the same genus. 
Euchloris Smuragdaria (the Essex Emerald, No. 7). This rare species has only been found at present on 
the Essex coast. The first specimen discovered was reared from a Caterpillar found by Mr. C. Parsons, near 
South Church, Essex, in June 1826. Specimens have since been taken at Southend and St. Osyth, both on the 
Tssex coast. 
The genus Comibeena, This is another genus established on the conformation and habits of the Caterpillar, 
rather than the characters of the perfect insect. Like the preceding, the Caterpillars of this genus’ form for 
themselves shells composed of portions of leaves, bark, &e. They are also humped in a similar manner on 
several of the segments, and may perhaps eventually, on farther revision of the group, be placed in the genus 
Smaragdaria, notwithstanding the existence of minute distinctions, unnecessary to allude to in a work of 
strictly popular character. 
Comibena Bajularia (the Blotched Emerald, No. 8) is not an abundant species. The Caterpillar (No. 9) 
feeds upon Oak, partially covered by its case of bark, lichens, &e. It is represented in the Plate without its 
protecting case. The Moth appears in Oak woods in July, and has been recently taken near Brighton, Bristol, 
Stowmarket, Tenterden, York, and other places.
