Ochsenheimer's genus Nonagria is so nearly related to Leu- 

 cania, that, excepting the strongly ciliated antennas of the males, 

 there is no character in the former that is not approached too 

 nearly by the latter to justify their being distinguished as ge- 

 nera. 



The following are British species of this rare genus, two of 

 them having been first recorded in my Guide : — 



1. N. Typhae Hiib. 8S. 415.— Gorfa, pi. 106. 8.— Arundinis 



Fab. 

 The larva lives in the stems of bulrushes, and closes the 

 hole, by which probably in most cases it entered, with a silk 

 web. It has been ascertained by M. Duponchel, that although 

 the caterpillars live in an ascending attitude, viz. with their 

 heads uppermost, the chrysalis is always placed the reverse, 

 with the head downwards, the hole for its exit being below it ! 

 The moth appears the middle of August. 



2. N. Canna? Ocli. — Goda, 106. 3.— Algae Esp. — Arundinis 



Hub. 83. 386 and 387. 



The caterpillar lives also in TypJia latifolia and Carex ripa- 

 ria. The moth appears the beginning of August. 



As the antennse are said to be filiform in both sexes, it is 

 doubtful if this moth does not belong to the genus Leucania. 



3. N. pilicornis Hatso. — Ste. pi. 29. f. I. 

 Taken near Croydon in September. 



4. N. crassicornis Haw. 173. 36. 



A male was taken by Mr. J. Hooker many years since in 

 Norfolk ; and the female in my possession was captured by 

 the late Mr. T. Mack, in a marsh at Hellesdon in the same 

 county. 



5. N. lutosa? Hiib. 48. 232. 



I have a specimen agreeing pretty well with the above figure, 

 that was taken in Derbyshire. 



6. N. Vectis Curt. Brit. Ent. pi. 459. 



I took a female amongst reeds and rushes near Black-gang 

 Chine, in the Isle of Wight, the end of July ; and another was 

 captured by Mr. B. Standish at Whitdesea Mere, the middle 

 of the same month. 



The Plant is Peplis Portula (Water Purslane).
