unusually long and pointed, as long as second joint is wide. Tongue 

 feebler than in Caustoloma, but of about the same size as in Nemato- 

 campa. Wings somewhat resembling those of Caustoloma, but not 

 angulated; fore wings with costa more convex than in Caustoloma, 

 but just as in Nematocampa and Venilia; apex obtusely pointed; 

 outer edge full convex, but not angulated; inner edge two-thirds as 

 long as costa. Hind wings much like those of Caustoloma in outline ; 

 but not hollowed out below the apex, neither are they convex, but 

 the edge is straight between the apex and middle of the wing. The 

 venation differs from that of Caustoloma, which it resembles most, in 

 the costal area being wider, and consequently the costal vein and 

 first three subcostal venules shorter and more oblique, and they are 

 nearer together. On the secondaries the second subcostal venule 

 arises much farther than usual from the discal spot, a third of the 

 way from the dot to the end of the vein, while in Caustoloma it arises 

 at the dot. The venation of the secondaries is more like Nemato- 

 campa. 



Hind legs long and slender, tibias with four stout spurs. Abdomen 

 long and slender, just reaching the anal angle. In style of coloration 

 the genus reminds us of Caustoloma, and more remotely of Nemato- 

 campa. The body and wings are yellow, with fawn colored costal 

 spots, and the edges of the wings are stained with fawn. In size the 

 only species yet known is intermediate between Caustoloma and 

 Nematocampa. Its large, long, acute palpi, simple antennae with tri- 

 angular joints, and its non-angulated wings, will distinguish the genus. 



Eurhinosea flavaria. 4 d", 2 9. 



Body and wings deep ochreous yellow. Palpi brown on sides of 

 second joint. Fore wings clear yellow, costa fawn brown at base, 

 two costal brown spots in the middle of the wing, the inner oblique, 

 the outer nearly straight. No lines in the middle area of the wing; 

 a small discal dot (sometimes wanting), a minute dot on the origin 

 of the third or lower median venule ; outer edge of the wing below 

 the apex broadly margined with fawn brown to, and enclosing, the 

 anal angle, the band being as broad as the thorax. Hind wings con- 

 col orous with the fore wings; a rather large dark dot close to the 

 origin of the first subcostal venule, a triangular marginal patch just 

 below the apex; otherwise no markings. Beneath, from a large 

 basal costal spot, proceeds a fine curved line across the wing, and 

 with a much curved one within, forms a ringlet. Beyond the con- 

 spicuous dark discal dot a broad diffuse pale brown shade crosses the
