218 Mr. A. G. Butler on new Lepidoptera 



The males of this species and A. hyporlioda are readily 

 separable from the males of Spilarctia by their slender an- 

 tennag. 



LithosiidsB. 



Sphragidium, gen. uov. 



Primaries oblong, triangular; costal margin of males bent 

 forwards from end of cell, owing to a projecting flap overlap- 

 ping the base of the subcostal branches ; costal vein running 

 close to the margin, with which it unites just before the end 

 of the cell so as to thicken the costa in front of the flap ; 

 subcostal vein quadriramose, distorted, running beneath the 

 thickened flap, where it becomes very weak, so that its con- 

 tinuity is scarcely traceable, emitting its first branch trans- 

 versely, immediately beyond the flap, to costal margin, the 

 three remaining branches running obliquely upwards to costa 

 with a slight bend at their origins, the fourth branch termi- 

 nating at apex ; upper radial diverging from the subcostal 

 branches, emitted beneath the flap from a scarcely perceptible 

 discocellular veinlet ; lower radial absent ; second and third 

 median branches emitted from the end of the cell and at some 

 distance from the first branch, all three curving slightly up- 

 wards to outer margin ; submedian vein extending from 

 base to outer margin, internal vein from base to external 

 angle : secondaries triangular, costal margin rather long, 

 frenum very long, single ; costal vein straight ; subcostal 

 forking a little more than halfway between the cell and outer 

 margin ; discocellulars equally inangled, the radial being 

 emitted from their centre ; second and third median branches 

 forming a furca emitted from a long footstalk ; first median 

 branch emitted before the end of the cell ; submedian and 

 internal veins running from base to outer margin. Body 

 robust, rather short ; the thorax very convex ; head wide ; 

 palpi short, rather smooth, closely scaled, apparently spinose 

 in front ; antennse long, rather thick, with fine and very short 

 ciliation ; legs thick, rather long, the tibiae of second pair 

 of legs with a short, strong, terminal spine, those of hind pair 

 with an additional subterminal spine. 



Type ;S^. miles. 



To this genus Dyphloehia tricolora and D. liboria must be 

 referred ; the genus I) i/phloebia being restricted to the African 

 species, which have only two median branches in all their 

 wings.
