192 Mr. H. T. Stainton on Gracilaria, 



immediately before the commencement of the cilia, it is small and 

 round ; the cilia round it are brown, with two darker curved lines, 

 formed by the end of the scales. 



Posterior wings narrow, gradually pointed, grey, with paler 

 cilia. 



First found in this country by Mr. Weir, in July, 1847, near 

 Tunbridge Wells, among Genista tinctoria. Mr. Weir informs 

 me that where he meets with it there is no Ononis at all, and he 

 presumes that it feeds there on the Genista. 



Zeller says that " its chief resort at Glogau is a fir plantation, 

 on a loamy hill, in a patch thickly grown with Ononis spinosa. 

 Here I first took the small, and easily overlooked, moths from the 

 middle of June to July. They can only be brought to fly during 

 the day by trampling down the plants, but on still evenings they 

 fly more readily, and are not hard to catch. They sit as the other 

 Gracilarice." 



" The larva, which is pale, greenish-yellow, with a honey-yellow 

 head, mines the lower, older leaves of the Ononis spinosa ; it 

 loosens the upper epidermis for the greater part of the leaf, and 

 devours the parenchyma; it leaves the lower skin of the leaf 

 quite uninjured, wherefore the leaves seen from below appear 

 quite sound. Towards the base or apex of the mined place or on 

 both are found collections of black excrement. The larva also 

 appears to go into fresh leaves, since I have sometimes found an 

 entire leaf mined, and the larva only in one leaflet. It crawls 

 rather slowly and spins a thread. At the end of May the larva 

 crept out of the dried leaves to seek a place suitable for spinning 

 up, often going far away. The white cocoon is placed in a 

 corner ; it is twice the size of the larva, and is pointed on both 

 sides. On the 14th of June the first moth appeared." 



** The species does not appear to be double-brooded." 



Sp. 23. Pavoniella (Metzner), Zeller. 



" Alis anticis subcaudulatis aureis, strigulis quatuor costae, 

 tribus dorsi lineolaque ex media basi argenteis, fusco-margi- 

 natis, puncto apicis atro, pupilla argentea." 

 Pavoniella, Z. Linn. Ent. ii. 362. 



" Most nearly allied to the preceding, easily recognized by the 

 hook in the cilia, the paler gold yellow ground colour of the ante- 

 rior wing and the silver marginal streaks directed obliquely to 

 one another. It reminds one most of the genus Lithocollelis. 

 " Rather larger than the preceding. Thorax golden-yellow.
