BOMBYCID^. 

 ARCTIIN^. 

 Genus ANTARCTIA. Hlibner. 



" <5 . — Head very prominent, owing to the long frontal hairs, which 

 form a conical horizontal tuft. Antennae with long even pectinations. 

 Palpi porrect, long and slender ; the tips acute, projecting beyond the 

 front. Thorax very pilose, remarkably stout, while the abdomen is 

 short conical, rapidly tapering to the subacute tip. The scales of the 

 prothorax are hardly distinguishable from those of the rest of the 

 thorax." 



' ' Primaries a little more than one-half as broad as long, being short, 

 broad and oblong. Costa straight, apex obtusely rectangular. Outer 

 margin straight, suddenly bending around near the inner angle. Cos- 

 tal nervure long, terminating near the ist and 2nd subcostals. Origin 

 of 4th very remote from 5th, arising near the outer margin. First 

 three median nervules ari.se much beyond the middle of the wing ; 

 the 3rd being close to the ist and 2nd.'" ^ 



"Secondaries reach farther towards the tip of the abdomen than 

 usual. Costa long, and straight ; apex rounded, a little produced ; 

 outer edge long, convex, not bent in the middle. The three median 

 nervules arise very near together, slightly angulated at their origins." 



" Legs somewhat slender, long, pilose. Body beneath very pilose.', 



" Coloration uniform tawny, with no markings except discal dots and 

 transverse bands of black dots.'' 



Packard, Proc. Ent. Soc. Phil., vol. 3, p. 122. 



? . — Very different structurally from the 6 ; antennae very minutely 

 pectinated, almost simple. Thorax above and below nearly smooth, 

 abdomen finely scaled. Anterior wings, with costa more convex than 

 in 5 , and the outer margin more oblique, making the tip more acute. 



Of this genus Dr. Packard says : "In form this genus closely re- 

 sembles Lederer's genus Ocnogyna in the much produced prominent 

 head, owing to the length of the frontal hairs ; in the deeply pectinated 

 large stout antennae ; the short broad wings and very short wooly body 

 and short abdomen. The costa of the primaries is remarkably straight; 

 the outer edce straight, making the apex rectangular, but they differ
