This species measures from 11 to 14 inch in the expanse of the fore wings, which are silky ashy-brown ; the 
costa darkest, with several small oblique pale markings near the tip; a pale dentated striga before, and a second 
behind the middle of the wing, edged with a dusky line, and between them the two ordinary stigmata placed 
obliquely to each other, with pale centres and edges ; a pale, slender, subapical, irregular striga, and a marginal 
row of small black oblong dots ; the hind wings pale ochreous, with the margin darker ; the markings vary in 
intensity in different individuals. The female differs in being rather smaller than the male, with the fore wings 
of an uniform dark livid brown, the markings being almost obsolete; the hind wings whitish, irrorated with 
brown, especially along the margin. Taken in August and September, in many localities of England, Wales, 
and Scotland, but by no means common. 
OPHIUSA, Ocusenurmer (pars). TOXOCAMPA, Guénéz. 
This curious genus has the palpi divergent, prominent, and with the terminal joint small but distinct in our 
typical British species. The head with a frontal tuft; the body slender, tufted at the tip in the males; the 
wings, when closed, forming a triangle, and very little deflexed ; the thorax and abdomen are not tufted. The 
caterpillars are 16-footed, and are half-loopers ; they feed upon low-growing leguminous plants. 
SPECIES 1.—OPHIUSA LUSORIA. Puare LIV., Fie. 10, 11. 
Synonymes.—Phalena Bombyx lusoria, Linneus; Hiibner ; Curtis, Brit. Ent. pl. 475; Donovan, 10, pl. 354, fig. 2; Stephens ; Wood, 
Ind. Ent. pl. 17, fig. 434. 
This species measures about 12 inch in the expanse of the fore wings, which are of a pale purplish-gray colour, 
thickly irrorated with darker transverse lineole, with one or two very dark brown dots, in place of the anterior 
stigma, and a larger conical spot, accompanied by two dots at its outer lower angle of the same colour, in the 
place of the outer stigma; a brown cloud runs parallel with the apical margin, in which is the rudiment of a 
very pale undulating striga ; the margin with a row of small dark dots; the hind wings are ochreous and 
freckled, with the margin slightly darker. There is much difference in the tinge of different specimens. The 
body is pale luteous, with the collar black-brown. The caterpillar is gray on the sides, the back striped longi- 
tudinally with white, black, and fulvous, and a black line above the feet ; 1t feeds on Astragalus glycyphyllos. 
The moth occurs in moist places, and in woods, and is very widely dispersed, being found in J uly and August, 
in the woods round London, and in Suffolk, Yorkshire, Cambridge, ‘‘ Teignmouth.”—W. R, H. Jordan, Esq. 

Obs.—The five following species have been introduced into our Lists of English Moths; but it is very 
questionable whether any of them are in fact natives of the old world. It is to be observed, however, that there 
. . , | 
are a considerable number of species of the genus Ophiusa found on the Continent of Europe 
PHYTOMETRA LUDICRA (Hiibner?) Haworth; Stephens (Ophiusa 1.); Wood, Ind. Ent. pl. 54, f. 53 
Closely allied to O. lusoria; fore wings brown acne 
| and speckled, with a dot and a short line in the middle black, and 
two obsolete strige towards the extremity of the wing; hind wings brown. 
Locality unknown. Expansion of fore wings 12. inch.
