946 LORD WALSINGHAM ON THE [Nov. 26, 



pale ochreons, the median joint shaded on its basal half with 

 black, and with a black spot on its distal half externally. Head 

 and Thorax pale ochreous, the latter slightly shaded with fawn- 

 brown anteriorly. Forewings pale ochreous, partially shaded 

 with umber-bi'own, especially below the fold, on the outer half of 

 the costa, and around the apex where the dark scales project 

 more or less through the pale ochreous cilia ; the extreme loase of 

 the costa is narrowly black, a few black scales being scattered 

 along the base of the dorsum ; at one-third from the base are tAvo 

 small black spots placed obliquely in the cell, sometimes confluent, 

 and beneath the outer one is a stronger black spot in the fold ; 

 beyond these, at the end of the cell and preceded by a small 

 elongate spot at its upper edge, is an oblique reniform patch, 

 covering the discoidal and produced inward from the upper angle 

 — these markings are subject to more or less modification, and 

 are less distinct in some specimens than in others, but their posi- 

 tion is uniformly maintained. Exjy. al. 13-14 mm. Hindwings 

 pale straw- whitish ; cilia pale ochreous. Abdomen and Legs pale 

 ochreous, the tibiae and tarsi slightly shaded with brownish on 

 their outer sides.

 Thirteen specimens. 



This species is somewhat larger on the average than Ajxdema 

 fasciatimi, and the forewings are uniformly broader ; their invariably 

 ochraceous ground-colour and the distribution of the black spots, 

 with the absence of any distinct shade across the base, serve to 

 distinguish it from its ally — like the forewings the hindwings are 

 also of an entirely different hue. It does not appear to be a 

 common species.

(a^t/3\w/xa =abortion.) 



Type Ambloma hracliyptera Wlsm. 



Antennae without pecten ; a little longer than the forewings ;. 

 simple in 6 . Maxillary Palpi short. Labial Paljn bent upwards, 

 reaching to vertex ; median joint moderately clothed with slightly 

 projecting scales below at apex; terminal joint short, smooth. 

 Head and Thorax smooth. Forewings very short, tapering rapidly 

 to a slightly depressed, obtusely pointed apex; costa evenly convex, 

 flexus rather squarely developed, dorsum straight beyond the 

 fiexus : neuration 12 veins; 7 and 8 stalked, to costa; 6 out of 

 stalk of (7 + 8) ; cell short. Hindwings f, much shorter, but of 

 the same shape as the forewings ; cilia 1| : neuration 8 veins ; 

 6 and 7 stalked ; 3 and 4 stalked. Abdoinen smooth. Legs, hind 

 tibiae moderately hairy. 



Allied to Ajxitema Wlsm. and Symmoca Hb., but differing in
