28 Mr. A. G. Butler on Heterocerous Lepidoptera 



Philanglaus, n. g. 



Aspect of the II. velleda group of Hepiahis, so far as 

 markings are concerned, but with pectinated antennae 

 more Hke those of Oxycanus ; the form of the wings 

 more hke that of the Phcdcridce ; primaries obtusely 

 triangular ; veins unusually simple for the family ; 

 costal vein extending to apex ; subcostal five-branched, 

 the first branch emitted near the base, second just before 

 the end of the cell, united by a very short cross-vein 

 beyond the cell to the third branch, which starts with 

 the fourth and fifth from the upper angle of the cell; 

 these three last veins diverge towards the outer margin ; 

 radials emitted from the disco-cellulars, which are 

 oblique ; two short recurrent veins from the lower radial, 

 united at the outer third of the cell ; median vein three- 

 branched, the last two branches emitted near together 

 towards the end of the cell, first branch much curved, 

 submedian sinuous ; secondaries subtrigonate, the basal 

 half of costal border projecting, very convex, apex 

 rather acute, outer margin convex and very slightly 

 sinuated between the veins ; abdominal margin straight ; 

 costal vein wanting, its place occupied by the subcostal, 

 which runs to apical fourth of costal margin, and has 

 no true branches, two radials emitted from the disco- 

 cellulars, which are transverse, diverging towards the 

 apex, the upper one emitting a recurrent vein backwards 

 through the cell almost to the base of the subcostal vein ; 

 median vein four-branched, the fourth (which represents 

 the true radial vein of other moths) emitting a looped 

 recurrent vein into the cell ; submedian represented by 

 two subparallel veins ; internal vein simple ; thorax very 

 robust, broad, narrowing behind ; head short ; palpi 

 short, thick, not extending in front of the head ; antennse 

 rather long (about two-fifths as long as primaries), pecti- 

 nated to the tijDS ; abdomen rather broad at base, taper- 

 ing and compressed towards the anal extremity; legs 

 rather long and thick, the tarsi being longest. 



44. Philanglaus ornatus, n. s. 



Primaries above with the costal area white ; the 

 oblique area crossed by the median and radial veins 

 greyish brown; the external and internal areas pale 

 sandy brown ; markings sharply defined dark ferruginous,
