400 Mr. R. Trimen on some New Species of 



"Forest on the hill above Frankfort, March 28th, 1861, — 

 abundant. Pitches frequently on tree-trunks, head downwards." — 

 D'Urban in litt. 



LYC^NID^, Leach. 

 Genus D'Urbania, n. g. 



Imago. — Head of moderate size : eyes ovate, smooth, rather 

 small, slightly prominent ; palpi rather long, porrected divergently, 

 scarcely rising above forehead, scaly, 2nd joint long and stout, 

 terminal joint slender ; antennae short (especially in $ ), rather 

 siout, with a well-marked, sub-cylindrical, rather abruptly-formed, 

 obtuse-ended club, and with conspicuous white rings ; no tuft of 

 hairs on forehead. Thorax compressed, short, not stout, with a 

 few short hairs laterally and posteriorly : prothorax with a dense 

 clothing of short hair. Wings large, elongate, rounded, entire. 

 Fore-wing : costa moderately arched from base ; apex rounded ; 

 hind-margin rather markedly convex, the anal angle being very 

 much rounded off; inner margin straight ; nervures short and weak, 

 yet with a slight inclination to be swollen at base ; the nervules 

 unusually long, the 1st svib-costal and 3rd median nervules being 

 inserted very near to base ; discoidal cell short, rather wide at 

 extremity, apparently closed by a scarcely-perceptible nervule. 

 Hind-wing : costa strongly arched just at base, thence almost 

 straight ; hind-margin as in fore-wing, the apical and anal angles 

 being yet more rounded off; inner-margins almost straight, just 

 covering the sides of abdomen, but no part of its under-surface, 

 being widely separate at its base ; discoidal cell closed, rather 

 longer and wider than in fore-wing. Legs short, the femora 

 stout, scaly ; tarsi of fore-legs of $ composed of a single elongate 

 joint, with the ungues obsolete, — those of 2 with the joints com- 

 pressed, and provided with minute ungues ; posterior tibiae in both 

 sexes destitute of spurs. Abdomen short, compressed. 



Larva and pupa unknown. 



I have dedicated this curious and interesting genus to my friend 

 W. S. M. D'Urban. It is, without question, the most valuable 

 result of his Kaffrarian researches. The single species on which 

 it is founded presents an aspect wholly at variance with that of the 

 typical Lyccenidce, possessing none of the metallic or silky lustre 

 of the Lyccsnce or Chrysopliani ; the general colouring and texture, 

 as well as the shape, of the wings, and the weak structure of the 

 body, forcibly reminding one of the Satjjridcs. The fuscous-and- 

 whitish irrorated under-surface differs widely from all those that
