Head with a rather narrow trout, and with a few long scales forming an 

 interpalpal tuft. Palpi ascending, the outer third or half of the second joint 

 surpassing the front; third joint minute, short, or moderately long, pointed. 

 Male antennee simple, compressed, ciliated beneath; in the female, simple and 

 filiform. Thorax slender. Abdomen usually very long and slender, with a 

 terminal tuft. Fore wings convex on the cost a; apex acute, rectangular, 

 sometimes very slightly falcate. Outer margin not very oblique, usually bent 

 in the middle. Tlie first subcostal vein free ; the subcostal areole very nar- 

 row, linear, not curved as in Thamvonoma; llie second and third subcostal 

 veins nearly (Mpial in length. The two discal venules run in a .straight line 

 across the wing, the posterior one being curved inward a little. Hind wings 

 produced toward the apex, not bent on the outer edge. Legs very long; 

 hind tibiae much swollen; spurs slender; hind tarsi a little more than half as 

 long as the hind tiliite. Coloration : pale ash-brown or whitish : either with- 

 out or with two transverse lines. 



This genus differs from Thammnomu, 1o which it is nearest allied by 

 the simple flattened antenii* and the longer legs. There is a parallelism 

 between the two genera in the most characteristic form, L. nigroseriata having 

 the wings much more tlilcate, the palpi longer, and the legs longer, while in 

 the lower species, such as L. (/isconvoita and airopunctata, the palpiand legs 

 are shorter, and the wings are not at all falcate, there being the same range 

 of variation as between Thaninouoma vxwarhi and T. fripunrlarln.
