 month of June.

This species measures scarcely half au inch in e.xpans(>. Its wings are somewhat more elongated than in 



the other species ; they are brown and shining, with the veins darker, and the margins of an ashy-white colour. 



The antenna; are greyish brown, and long with short pectinations ; the hind wings are rounded, clearer coloured 



than the upper wings. 



The caterpillar incloses itself in a ease formed of bits of grass arranged longitudinally, as represented in our 

 figure near the tiji of the left wings of the male of ApoJa lestudo (fig. a). The moth is very rare, but has been 

 found several times near Darenth Wood in Julv. 



Fumea Bombycella, lliihner, Ochsenheinier. and our plate ](!, fig. 14, was given by Stephens as identical 

 with the Fumea muscea of Ilaworth, but it is not a British species. It is larger than any of the ])recedinT, with 

 the wings rounded, and of a livid colour, freckled with brown spots. 



PSYCHE. Stepiikns. STERRFIOPTRYX, Huiixer. 



The typical species of this genus differs from the other Sack-triigers by having short antcnnw with short curved 

 pectinations in the male, and very short and slender ones in the females. The fore wings arc elongate, triangular, 

 with the veins arranged in a curious manner, the third branch of the median vein being forked close to its origin. 

 They are very trans])arent, and but .slightly hairy. The female is small, but very robust ; destitute of wings, 

 with the legs short ; the extremity of the body clothed with a woollen mass, with the ovipositor exserted.

The male of this curious species measures about three-quarters of an inch in the expanse of its fore wings, 

 which are of a very pale uniform grey-brown colour, without any spots or markings, and transjiarent ; tlie antenuce 

 of the males dusky brown, the abdomen pale-ashy coloured, with an ochreous tinge. The female has the head and 

 thorax shining brown, and the sides of the abdomen grey. 



The caterpillar is fleshy white, with the head and three anterior segments of the body spotted with dark 

 brown, the spots varying in size, the legs increase in length, thus resembling the larva; of Oiketicus of Guilding, 

 figured in the LinnEean Transactions. The case is composed of bits of leaves and sticks fastened together without 

 the least regularity. The caterpillar feeds on the leaves of oak, willow, whitethorn, and hazel, in June and July, 

 and the moth appears in the latter month. I have an extended scries of observations on the natural history of 

 this insect in manuscript, illustrated with numerous figures, having, in company w-ith Mr. Ingpen, found the larv;t 

 in Hornsey Wood, Middlesex, in 1827. It lias also been found in other adjacent localities, but Mr. Ingpen 

 informs me that ho has more recently searched for the larvas in vain, although we found them in the utmost 

 profusion.
