Veins 7, 8 and 9 nearly always on one stem. In very many 

 species, more generally in the 11- veined ones, there is a vitreous 

 spot or fovea, as Mr. Meyrick calls it, at the base of la in the 

 fore wings beneath. In a few cases a pencil of hairs near the same 

 spot. In one of our species there are 8 veins only in the fore 

 wings, and in very many the relations of 10, 11 and 12 are ex- 

 tremely variable, these separating or anastomosing in the indi- 

 vidual species without regard to uniformity. In some cases there 

 is no accessory cell, in many there is one, in many two. In some 

 cases there is a subcostal cell, but 12 is generally free. 



The hind wings have normally 8 veins. There are one or two 

 internal veins, and the position of all veins presents great varia- 

 tion. Veins 3 and 4 generally separate, are sometimes stemmed. 

 Vein 5, generally near the centre of the outer margin of the cell, 

 is very often wanting, or merely a fold. Veins 6 and 7 may be 

 separate or stemmed; vein 8 may be stemmed with the anterior 

 part of the cell, joined near its base only, joined by a short cross- 

 bar, or entirely separate. The wing often has a vitreous spot or 

 fold below at base near vein 8, and the inner edge is quite often 

 modified by a fold and hair tuftings. 



The abdomen is slender, rather long, sometimes with lateral 

 or dorsal tufts in the male. 



The legs present very considerable variation. They are gen- 

 erally long, slender and frail, in some cases very long. The fore 

 tibiae are rarely spined. The epiphysis is always present, and is 

 often prolonged to beyond the end of the tibiae. 



The middle legs are, with one exception, armed with a pair of 

 spurs at the end of the tibiae, and are very uniform. 



The hind legs are generally longer than the others, and are 

 usually with a pair of spurs at the end, and another pair above 

 near the middle of tibia. In a few cases the legs are. so much 

 aborted as to be useless, and in a few are simply rudimentary in 

 character. Many are furnished with a long pencil of hairs; this 

 starts from the upper portion of the tibia and reaches to the lower 

 end, being ordinarily concealed in a long groove on the inner 

 side; where the hair pencil exists there is always a swelling and 

 enlargement of the tibia, and a shortening and abortion of the 

 spurs and tarsi. This is a characteristic of the males, though in 

 some cases there is a loss of spurs in the female. The history of 

 variation in the hind legs seems to be as follows: The legs are
