Phalena Nociua Lappe; Donovan, 10, pl. 340. Noctua rutilago, Fabricius. 
This elegant species measures from 14 to more than 12 inch in the expanse of the fore wings, which are of a 
rich orange yellow, beautifully mottled with 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 characteristic 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 purplish 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 
broadish 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 figures of the distinct species N. Typhe are from specimens sent me by Mr. H. Doubleday. The continental N. Canna is from 
a German specimen iu 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 Typhe is from Freyer; that of Canne from 
Hiibner. H. N. H. 
NONAGRIA, OcnsenHEIMeEr. 
This genus is distinguished by having the antenna 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 larve are also long and naked, with a small head, and with the body marked with 
pale longitudinal streaks, and the anterior and posterior segments scutellated. ‘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. 8. 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 will 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.
