Tue fourteenth sub-family of the Geometride is that of Cidaridi, containing fifteen genera; Electra, 
Harpalyce, Steganolophia, Lampropteryx, Anticlea, Aplocera, Chloroclysta, Hydriomena, Polyphasia, Thera, 
Cheimatobia, Oporabia, Acasis, Lobophora and Eupithecia. 
The genus Electra (the Cidaria of Treitschke). The insects assigned to this genus, are pretty generally 
distinguished by the various yellow tints of their wings, the anterior pair having a rather narrower and more 
elongate form than in the preceding group, and having also the anterior tip marked by an oblique stripe or patch 
of alight or dark colour. The antenne are generally simple in both sexes. The body is rather long, especially 
in the males, which have a tuft at the extremity. The Caterpillars are slender, and attenuated towards the 
head, which is often of forked or bifid form. The Chrysalides are distinguished as being frequently of various 
colours. There are six British species. 
Electra populata (the Northern Spinach Moth, No 1). The appearance of this insect was formerly 
considered to be confined to Scotland and the North of England, but it has recently been discovered plentifully in 
more southern districts. The caterpillar (No 2) feeds on Poplar, and the perfect insect appears in July. In the 
neighbourhood of Huddersfield and Edinburgh it is found in great abundance ; and in less plenty in southern 
localities, such as Brighton, Darenth Wood, Plymouth, &e. 
The other species are Z. sagittata (the Marsh Carpet) having the front wings of pale brown, with a broad 
cross band on a basal patch of blue-black, edged with a bright border of white. Z. chenopodiata closely resembles 
E. populata, but has the dark band stronger, and the oblique patch at the angle of the front wings reduced to a 
broadish streak. #. achatinata (the Broad Chiverned Moth) is very like the preceding, but paler, and has two 
brightish cream-coloured bands near the margin of the fore wings, one enclosing the oblique blotch, and the other 
at the outside of a partly obsolete dark band. JZ. pyraliata (the Barred Straw) is distinguished by having three 
narrow bands across the fore wings, and a row of spots near the edge. Z. marmorata (the Spinach) is very like 
populata, but rather larger, and has the band more distinctly defined, and the ground in some places lighter. 
It is the handsomest of the genus. These species are all common except the strikingly marked &. sagittata, 
which at present has only been found in the fens of Cambridgeshire, and is very rare. 
The genus Harpalyce formerly containing eleven British species, is now restricted to six, the others having 
been more correctly located in other genera. Those retained in this genus have the antenne of both sexes 
simple. The wings are short and triangular, and all four wings are extended, forming a broad triangle when the 
insect is atrest. The caterpillars are ten footed, and the chrysalides smooth, and often varied in colour.
