Fig. 20),—Expanse, 14 inches. Local, but not un-

The larva may be found all through the summer. 
Family CyMATOPHORID&. 
Thyatira derasa: the Buff Arches (Plate V., Fig. 3). 
—The Cymatophoride are a small family of three 
genera and nine species which were formerly classed 
with the Noctuz. According to the neuration of the 
wings, they differ slightly both from the pseudo- 
Bombyces and the Noctue. Derasa is a fairly 
common species; the larve feed on Bramble and 
Raspberry, and are not difficult to rear; they are 
found in August and September. Moth in June and 
July. It comes to sugar. Expanse, 13 inches. 
Thyatira batis: the Peach Blossom (Plate V., 
Fig. 7).—Also feeds on Bramble and Raspberry, but 
more openly than the last species. In fact, the larve 
of the whole of this group havea peculiar habit of sun- 
ning themselves on an open leaf, and there bending 
themselves almost double, like a horseshoe; while rest- 
ing in this position they greatly resemble bird-droppings, 
and are thus, no doubt, often overlooked by enemies. 
Batis comes freely to sugar. Larva in August and 
September, moth in June. Expanse, rather over 17 
inches. Common nearly everywhere. 
Asphalia flavicornis: the Yellow- Horned Moth 
(Plate V., Fig. 6),—Expanse, 13 inches. A common, 
widely-distributed species appearing in early spring.
