broader, with a pale blotch between the hinder margin and the very 

 black clavifonn stigma. 



6. Tapinostola Bondii, Knaggs. 



A good new species, discovered by Dr. Knaggs, in August, 1859, 

 on the coast of Kent, and named by that entomologist. Larger than 

 Nonagria fiilva and N. concolor of Gaenee (? extrema, H., female), 

 resembling the latter in colour, and differing from both in form. The 

 body appears to me comparatively more slender, the antennae of the 

 male somewhat thinner than in either ; the fore wings are much 

 broader than in N. fulva, but longer than in N. concolor; the oblique 

 direction of the hind margin is intermediate between the two ; the 

 coloration is whiter than in N. concolor — iu the male throughout uni- 

 formly irrorated brown-gray, in the female only towards the strikingly 

 whiter unspotted cilia ; the row of dots the same as in N. concolor. 

 In the male the hind wings are entirely irrorated with black-gray, 

 somewhat darker near the hind margin ; in the female the black-gray 

 scales are more confined to a curved line behind the middle and at 

 the hind margin. The fore wings are black-gray beneath, paler near 

 the hind margin and near the costa ; the hind wings are much whiter, 

 the curved dark line being distinct in the male only. The legs are 

 clothed with more blackish scales. 



7. Nonagria concolor, Guenee. 



I must here take the opportunity of making some observations 

 respecting the above-mentioned Nonagria concolor of Guenee. It is 

 briefly, but pretty distinctly, described by Guenee (1852), No. 158. In 

 English works it first appears in 1850, as N. extrema, in the ' List of 

 the Specimens of British Animals,' with the reference H. fig. 412 : from 

 this it appears that Mr. Stephens, the compiler of this List, had no 

 doubt of its identity ; he probably had similar specimens before him. 

 I must, however, confess that the few specimens of jthis species which 

 I have seen, and also those which I have represented at fig. 337 in 

 my systematic work, diflfer too essentially from Hiibner's figure to 

 warrant the retention of that author's name, and the less so that I have 

 myself in the above-mentioned work, page 228, vol. ii., under the 

 name of N. extrema, which at most can be given to the female, quoted 

 a male, which indeed unquestionably belongs to N. Hellmanni.
