188 LEPIDOPTERA. 



Australian species. In the allied East Indian genus Spiramia, 

 GU&L, the ocellus on the fore wings assumes a peculiarly irregular 

 form (Fam. Hypopyridce). 



Lagoptera, Gu6n., is an East Indian genus with rather pointed 

 fore wings, with an oblique line running from the tip. The hind 

 wings are very varied in colouring, being red, with a short 

 blackish dash in one species ; yellow, with two black bands, in 

 another; and black or brown, with a blue or white band, in 

 others. They are the largest of the Ophiusidce, measuring three 

 or four inches across the wings. The species of Ophiodes, Guen., 

 are smaller insects, with green or brown fore wings; the hind 

 wings are generally yellow, with a black dash towards the 

 borders. They inhabit the tropics of the Old World ; but one or 

 two species are found in Europe. A great number of species of 

 smaller size, belonging to this family, inhabit the Tropics ; these 

 chiefly belong to the genera Ophisma, Gu6n., Achcea, Hiibn., and 

 Ophiusa, Ochs. 



The Amphigonidce, with two allied families, have been called 

 Pseudodeltoidce, from their resemblance to the Deltoidce, a family 

 formerly included with the Pyrales. They have rather slender 

 bodies, and triangular fore wings ; and the legs are frequently 

 adorned with a fan-like tuft of hair, a character often met 

 with in the Catocalidce, and in several of the other less typical 

 families of Noctuce. The Pseudodeltoidce are entirely exotic. The 

 borders of the wings are often of very irregular shapes in the 

 Amphigonidce, but less so in Amphigonia, Gue"n., than in some 

 allied genera. A. Hepatizans, Gu6n., is an Indian species, with 

 white and violet markings. Hypernaria Miniopila, Gu6n., may be 

 taken as our representative of the extensive family Thermesiidce, 

 which is almost entirely American. It is violet grey, with an 

 oblique brown line dusted with greenish yellow, and there is a 

 pale-red tuft of hair at the base of the intermediate tibiae. It is 

 a native of Cayenne. 



The Deltoidce derive their name from the triangular appearance 

 of many of the species when at rest. Their bodies are slender, 

 their wings ample, and their palpi are often very long. They 

 were formerly included with the Pyrales, but are now generally 

 placed at the end of the Noctuce. They are divided into three 

 sub-families. 



The species of Macrodes, Gue"n., are South American insects, 

 with very long antennse, ascending palpi, and broad wings, ex-
