dorsal spot rather nearer the base than the first costal spot 

 and exterior to the dark margin, it is silvery, dusted with 

 blackish ; the second costal spot is not as distinctly angled in 

 the middle, and the apical spot is larger ; in some specimens 

 there are two dorsal white lines on the thorax. The general 

 resemblance between the two is so marked that I consider it 

 unnecessary to designate it as a variety, for it is undoubtedly, 



1 think, the same insect. 



With a single subcosto-marginal nervule. 



Ce'Jf/i'}"/& 3. L. Desmodiella* Antennas dark brown, tipped with a 

 silvery hue. Front whitish, with a ruby-coloured lustre ; 

 frontal tuft dark brown. Thorax with a splendent ruby hue. 

 Fore-wings ferruginous-brown, ruby-tinted at the base, with 

 two silvery bands dark-margined on both sides, one near the 

 base and one in the middle of the wing. A costal and dorsal 

 silvery spot near the tip, opposite to each other, and a costal 

 silvery spot just before the tip, the two former dark-margined 

 on both sides, and the latter slightly dark-margined. No 

 hinder marginal line ; the cilia opposite the last dorsal spot 

 blackish, and the wing beneath the last costal spot golden- 

 brown. Hind-wings pale brownish-gray, cilia the same. 



The larva may be found in the leaf of Desmodium viridi- 

 Jiorum in July and early in August ; it mines the under 

 surface, usually near the margin, which is more or less folded, 

 and the separated epidermis brown and hairy. I have no 

 description of the larva. It becomes a pupa during the latter 

 part of August, and is suspended within the mine in a very 

 slight web of silk. The perfect insect is the smallest of this 

 group that has come under my observation.

 beneath. Front silvery-white ; tuft dark brown. Fore-wings 



• I received three specimens of this insect from Dr. Clemens ; it is very 

 splendid and like no European species ; the form of the wings is more like a 

 Gracilaria than a Lithocollctis. The exp. al. (omitted by Dr. Clemens) is
