BRITISH MOTHS 



SPECIES 1.— STILBIA ANOMALATA. Plate LIV., Fig. S, 9. 



SvNONVMES. — Phalcena anomalala, Hawortli, in Eiit. Trans, (old 

 scries, 1812), vol. i. p. 33C; Stcjiliens ; Cmtis, Biit.Ent.pl. 631; 

 Wood, lud. Ent. pi. 17, %. 435. 



Geometra hyhridata, llUbner. 



Caradrina stagnicola, Troitschke (nee BJv. & Puponchel). 



Ophiusa Lathi/ri, Boisduval. 



This species measures from li to 1^ 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 dcntated 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, OCHSE.MIEIMER (PARs). TOXOCAMPA, GUENEE. 



Tills curious genus has the palpi divergent, prominent, and with the terminal joint small hut 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 1 6-footed, and are half-loopcrs ; they feed upon low-growing leguminous plants. 



SPECIES 1.— OPHIUSA LUSORIA. Plate LIV., Fig. 10, 11. 



Synonvmes Phalana Bombyx lusoria, Linnceus; Hiilmer ; Curtis, Brit. Ent. pi. 475 ; Donovan, 10, pi. 354, fig. 2 ; Stephens ; Wood, 



Ind. Ent. pi. 17, fig. 434. 



This species measures about 1 4 inch in the expanse of the fore wings, which are of a pale purplish-gray colour, 

 thickly irrorated with darker transverse lineolae, 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; it feeds on Astragalus glycyphyllos. 

 The moth occurs in moist places, and in woods, and is very widely dispersed, being found in July and August, 

 in the woods round London, and in Suffolk, Yorkshire, Cambridge, " Teignmouth." — JV. B. II. Jordan, Esq. 



Ohs. — 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. pi. 54, f. 53. 

 Closely allied to 0. lusoria ; fore wings brown and speckled, with a dot and a short line in the middle black, and 

 two obsolete strigce tov?ards the extremity of the wing ; hind wings brown. In Mr. Swalnson's cabinet. 

 Locality unknown. Expansion of fore wings 1 j inch.
