 EUMACARIA Packard. Plate 3, Bg. 7. 



Eumacaria Pack., Filth Rep. Peal). Acad. Sc, G7, 1873. 



Front rather narrow; scales rather long, closely appressed to the surface. 

 Palpi long, narrow, ascending; a third of second joint surpassing the front; 

 third joint minute, pointed. Antenna' broadly pectinated nearly to the tip; 

 in female, subpectinated, serrate. Thorax rather stout. Primaries: costa a 

 little convex; apex a little produced, but much less so than usually in Semio- 

 thisa or Phasiane, slightly subfalcate; outer margin not so oblique as in 

 Semiothisa, hardly excavated below the apex, rather convex in the middle. 

 Venation much like that of Semiothisa and Phasiane; the costal vein is, 

 however, longer, and ends beyond the subcostal areole by a distance equal to 

 half the length of the areole, while in Semiothisa it ends opposite the end 

 of the areole-; the costal also connects with the areole in its middle, while in 

 the two other genera named it joins the areole near the inner end. The first 

 subcostal venule is longer, and the second much shorter, than in Semiothisa 

 or Phasiane. The discal venules are as in Semiothisa. Secondaries with the 

 internal angle rectangular, even with the tip of the abdomen. Apex much 

 rounded; middle of outer margin not produced, obtusely slightly angulated, 

 above slightly scalloped. Legs short and feeble; hind tibiae slightly swollen, 

 the two pair of spurs not remote, slender, pointed, subequal; tarsi half as 

 long as the tibiae. Abdomen very slender, with an anal tuft. 



Coloration: cinereous, dusted thickly with brown; an outer obscure line 

 of black spots; margin dark-brown. 



By the pectinated antenna 1 , long, slender palpi, and short, obtusely-angu- 

 lated secondaries, as well as the peculiar coloration, it may be readily distin- 

 guished from Setniotlusa. The markings and the antenna? remind us more, 

 of Epione and allied forms than Semiosthisa, Phasiane, and its allies. In the 

 venation, it entirely differs from Ej'ione and its allies. Anticipating Epione, 

 etc., in the characters of the antennae and coloration, and its peculiar aspect, I am 

 inclined to regard this as a synthetic or prophetic type, and therefore a true 

 mimetic form, and indicating that by its present mimicry it has been preserved 

 longer than the species possibly cotemporaneous with.it.
