Thi8 elegant species measures from 1 l to more than ]l inch in the expanse of the fore wings, which are of a 

 rich orange yellow, beautifully mottled witl, red brown scales and purplish brown markings. At the base of 

 the wing is a trilobed yellow patch, followed by a purplish brown bar, succeeded by the clilracteristic part of 

 the wing which bears the three stigmata ; the inner one small, round, and pale yellowish-buff ; the outer one 

 larger and ear-shaped, mottled with red scales within; the supplemental one semi-oval, all being surrounded by 

 slender reddish brown lines. Beyond the stigmata is a curved catenated series of yellow arched dots, followed 

 by a puri)lish bar, which is succeeded by the much waved, almost obsolete, subapical striga, formed of fulvous 

 arches. The cilia purplish brown ; the hind wings pale brown, with a slender striga beyond the middle, and a 

 broadisli subapical fimbria. 



The caterpillar is dirty flesh-coloured, dotted with black setigerous tubercles. The scutellation on the segment 

 behind the head, and the terminal segment of the body, black. It feeds within the stems of various aquatic or 

 subaquatic plants, such as the burdock, Scrophularia, &c. The moth appears in August and September. It is 

 a rather common and widely dispersed species.

The two fignri's of the distinct species N. Typha; arc from specimens sent me by Mr. H. Doubleday. The continental N. Cannse is from 

 a German specimen in the British Museum. All the others, which it is now generally admitted are but varieties of one species, are from fine 

 fresh specimens recently taken by Mr. S. Stevens, at Hammersmith. The caterpillar of Typba; is from Freycr ; that of Canna from 

 HUbner. II. N. H. 



NONAGRIA, OCHSENHEIMEH. 

 This genus is distinguished by having the antennre slightly crenulated and strongly ciliated in the males, but 

 merely pubescent in the females ; the palpi are bent upwards, rather small, and with the terminal joint minute. 

 The thorax is not regularly crested ; the fore wings deflexed when at rest, elongate trigonate, with the tip acute. 

 The body is elongated : the larvas are also long and naked, with a small head, and with the body marked witli 

 pale longitudinal streaks, .and the anterior .and posterior segments soutellated. They live concealed within the 

 stems of Gramineous and Cyperaceous plants ; within which they also undergo their transformations. The 

 indigenous species of this genus appears to require a minute revision, as the recent captures of Mr. S. Stevens 

 have shown that one species, at least, is subject to remarkable variation. This genus is so closely allied to 

 Leucania, that authors are by no means agreed in the generic position of various species, as wU be noticed in the 

 synonymes of the different insects. It is only by a more perfect knowledge of their preparatory states that we 

 can hope to determine this question satisfactorily.
