the abdomen extending far beyond the anal angle. Expands about i inch. Inhabits Central 

 Europe and the Altai from July to September, occurring in woods and damp meadows. The 

 larva is dirty white, with two indistinct and interrupted suffused yellow str-ipes on the back.

* 3. T. Hclhnanni (Eversm.).— Fore-wings short, with the tips pointed and rather produced ; 

 straw-colour, often suffused with reddish, and dusted with brownish ; the reniform stigma is 

 indicated by a pale space, filled up beneath with darker, and the elbowed line is indicated 

 by an indistinct row of dots. The hind-wings are dusted with grey, and the abdomen only 

 extends a little beyond the anal angle. Expands from i to i^ inches. A local insect, but 

 found throughout Central Europe from June to August, and also in the Altai. The larva is 

 spindle-shaped, white, with the back reddish, the head yellowish-brown, and the plates yellowish.

*4. T. Extrema (Hiibn.). — Fore-wings whitish-ochreous, suffused with grey, with a row of 

 black dots beyond the middle ; hind-wings grey. Expands about i inch. Widely distributed 

 throuo-hout Central Europe in June, but local, and generally rare. It is a fen insect, and is 

 now extinct in many places. 



* 5. T. Bondii (Knaggs). — Much resembles Extrema, but rather larger ; the fore-wings are 

 paler above and much darker below, and the hind-wings are darker above. It is a more 

 slender insect, with longer antennae, and the legs and palpi are much less hairy. It occurs at 

 Folkestone in July, and has also been taken in Greece. 



* 6. T. Elymi (Tr.). — Fore-wings long, with the costa and inner margin parallel ; greyish- 

 yellow, dusted with grey, especially below the costa, along the costal nervure, and on the 

 nervules before the hind margin ; a row of black dots beyond the middle. Hind-wings white, 

 and the abdomen long. Expands about \\ inches. It is found in sandy places on the south 

 coast of the Baltic, and has also been met with in the Norfolk Fens, occurring from June 

 to August. The larva is thick, whitish, with a pale brown head and dull red back. It lives 

 in the lowest joints of Elymus arcnarnts from September to May. 



GENUS X. — SESAMIA (GUfiN.). 

 Body stout, fore-wings nearly rectangular at the', tips, brownish, without any distinct pattern ; 

 antennae rather short ; palpi extending rather beyond the head, the last joint nearly one-third 

 of the length of the second ; and the tongue is short. The commonest species, S. Noiiagrioidcs 

 (Lef ), has greyish-yellow fore-wings, with the hind margin and a streak on the disc darker ; 

 a black discal spot, and an outer row of black dots ; hind-wings white. Inhabits Spain, North 

 Africa, and Madeira. The larva lives in the stalks of maize, corn, reed, sugar-cane, &c. (In 

 5. Cretica, Led., which inhabits South-Eastern Europe, the antenna of the male, which are 

 slightly pectinated in Nonagrioides, are filiform and ciliated, and the larva is shorter, and whitish, 

 instead of being suffused with violet.) 



GENUS XI. — ARGYROSPILA (HERR.-SCHAFF.). 

 Body slender, fore-wings long and narrow, with the tip truncated and the hind margin 

 oblique. The antennae are short, slender, and setose, very finely ciliated in the male ; the
