GRACILLARIA, Haworth. ORNIX, Treitschke. 

 These curious insects are distinguished by their densely-squamose middle tibiss, which, when the insect is 

 at rest, with the tarsi, are placed almost in an upright direction, and almost at right angles with the body, so that 

 the insect's head is greatly elevated, whilst the extremity of its wings rests upon the surface on which it is 

 placed ; the antennje are long and slender ; the maxillary palpi are short and straight, the labial ones rather 

 long, slender, and recurved ; the fore wings long, and the hind ones linear, with very long fringe. The cater- 

 pillars are fourteen-footed, having three pairs of abdominal feet. 



Species 1. — Gracillaria nebulea — (Haworth, 8ec. ; Wood, fig. 1605 ; and our Plate CXXI., Fig. 2) — 

 Expands 4 to 5 lines ; fore wings whitish -brown, or ashy, with large black nebula, the costa fasciated with 

 black, interrupted by whitish strigs. Taken in hedges, in the spring. 



Species 2. — Gracillaria meleagripennella — (Iliibner, &c. ; Wood, fig. 1606; and our Plate CXXI., 

 Fig. 3) — Expands 3h to 5 lines ; fore wings blackish, with white nebulte, the costa streaked with black and 

 white at the tip, and the extremity of the wings with a somewhat ocellated black spot. Darenth Wood, June. 



Species 3. — Gracillaria syringella " — (Fabricius ; Stephens; Wood, fig. 1607 ; and our Plate CXXI., 

 Fig. 4) — Expands 4^ to 6 lines; fore wings ochreous-tawny, freckled with brown, with about five more or 

 less interrupted and anastomosing fascia, the apical one forming an ocellus, with a black pupil ; hind 

 wings ashy-brown. The caterpillar, when young, feeds within the leaves of the common lilac, devouring the 

 parenchyma, and causing the leaves to blister; it afterwards, however, rolls the leaf up, feeding within the roll. 

 The perfect insect is common in gardens in May and July, being double-brooded. See Mr. E. W. Lewis's 

 observations on this species, in Loudon's Mag. of Nat. Hist., Vol. VI.
