ZEUZERA, Latretxe. 
Lest 
This genus is at once distinguished by the antenne of the males, which have a double series of pectinations 
extending only half the length of the antenne ; whilst in the females they are simple, and with the base woolly. 
The body is also woolly, and the wings more elongated than in Cossus. The palpi are very small, and the 
spiral tongue is almost obsclete. The veins of the wings offer a singular mode of distribution, the discoidal cell 
being divided into several areas, and terminated by several angulated veins. The caterpillar (in the typical 
species) has the body spotted. It feeds, like that of the goat moth, in the interior of trees, and, like it, forms a 
cocoon of chips of wood agglutinated together.

This beautiful insect, which from its markings has obtained the name of the wood leopard, varies from rather 
more than two to nearly three inches in the expansion of the fore wings, which are of a snowy-white colour, 
semitransparent, and marked with a great number of shining blue-black spots, which are more distinct in the 
females than in the males; the hind wings are similarly coloured, but the spots are less distinct ; the veins of 
the wings are of yellowish ochre. The thorax white, with six large black spots; the abdomen banded with 
blue-black. The caterpillar is pale ochre-yellow, with a large scaly black patch on the segment following the 
head; each of the other segments is marked with a number of shining black spots, from each of which issues a 
short hair; the anal segment has also a dark patch above. It feeds on the wood of the elm, pear, apple, lime, 
horse chesnut, walnut, ash, beech, birch, hazel, &c., burrowing into it in the same manner as the caterpillar of the 
goat moth, to which indeed it is very similar in its habits. It is found in numerous parts of the country at the 
beginning of July, although nowhere abundant. In St. James’s and Hyde Parks it is not uncommon in certain 
seasons, but it must be sought for early in the morning, as the sparrows consider the body as great a treat as 
the old Romans deemed the Cossi; their ravenous propensities being often indicated by the wings of the 
moth found at the bottom of the stems of the trees in which the moth had been reared. Many particulars 
relative to the habits of this insect will be found in Loudon’s Arboretum Britannicum, p. 887, and in Kollar’s 
treatise above referred to.

This species differs from the preceding not only in its small size, being only 14 inches in expanse, but also in 
having its fore wings of a dull uniform yellowish or ochreous-grey colour, somewhat like that of dry rushes, 
upon which plant the larva (which is figured by Boisduval in the ‘‘ Collection Iconographique des Chenilles 
d'Europe”) feeds. The fore wings in fine specimens have a few small dots or slight markings of a brownish
