arched, and the apex acute ; the palpi are broadly conical at the tip, with the terminal joint exposed. Two 

 specimens were taken at Whittleseamere, in July in 1824, by Mr. Bentley, in whose cabinet they are preserved. 

 This insect ought probably to be formed into a distinct genus.

ABLABIA, HiJBNER; Stephens. BACTRA,** Curtis (599). 

 The palpi in this genus are much more elongated and slender than in the preceding, with the penultimate 

 joint not covered by a clavate mass of scales, and with the terminal joint moderately long, and quite distinct ; 

 the antennae are simple ; the head slightly tufted in front ; the fore wings glossy, acutely-truncate at the tip ; 

 the disc plain, and nearly destitute of markings. 



Species 1. — Ablabia 4-punctanas — (Plate LXXXVIL, Fig. 13) — Measures from 9 to 11 lines in 

 expanse ; fore wings rufescent or pale, with a reddish tinge, varied with small dusky blotches, placed longitu- 

 dinally : the first small before the middle, the second thrice as large, and angulated near the middle, the third 

 near the apical margin, and the fourth nearly at the anal angle ; the costa obsoletely spotted with brown : hind 

 wings dark reddish-brown. The markings on the wings vary greatly in intensity. One received by Mr. 

 Haworth from Mr. Dale, with the name of Cantiana, now in my collection, has the first spot scarcely visible, 

 the second small and oblong, and the others obliterated, the inner margin hoary, and the apical portion of the 

 wing irrorated with brown dots. A very widely-dispersed species ; taken but rarely, in July and August.

Species 2. — Ablabia expallidana *■ — (Plate LXXXVII., Fig. 11) — Measures ^ an inch in expanse; 

 fore wings entirely pale whitish-buiF and seniipellucid, with a huffish tinge along the costal margin; the palpi 

 are deflexed, * with the terminal joint distinct, and the preceding joint much less thickly squamose than in the 

 types of the genus Bactra. The insect has, indeed, much of the appearance of some of the insects of the following 

 family, but the arrangement of the veins of the wings reduces it to its present station.

 All the insects on this plate are from Mr. Bentley's cabinet, except 

 C. ourrifasciana, which is from Mr. Wood's very excellent figure. 



Mr. Stephens' specimen does not probably belong to the genus, as he describes the palpi as slightly curved over the back. 5Iy description 

 is made from Mr. Haworth's typical individual now in my cabinet.
