XII. Description of the genera Argyrophyes and 

 Condylolomia and of a species of Deuterollyta 



BY AUG. R. GROTE. 

 [Bead before this Society, October 23, 1873.] 



Arg-yropliyes,^ n. g. 



Ocelli wanting. Maxillae rudimentary, entirely concealed by the prominently 

 long, very thickly scaled labial palpi (Plate 5, fig. 1), which exceed the front, 

 their third article directed forwards. Wings full ; primaries (Plate 5, fig. 3) 

 large, with evenly arcuate costa, straight external, and consequently long 

 internal margin ; 10-veined ; cell long, closed ; 2 to 5 at decreasing intervals ; 

 6 from the cross vein ; 7 to apex ; 8 out of 7 to costa ; 9 from upper and outer 

 angle of the cell to costa ; 10 and 11 wanting. Hind wings (Plate 5, fig. 3) 

 rounded, rather disproportionally smaller, 7-veined ; cell incompletely closed, 

 angulated ; vein 5 wanting ; no accessory internal veins ; on both wings the 

 cells are undivided. 



The species is frail, white, pulverulent, with somewhat the out- 

 line of Homophysa, so that at first, and considering the bushy palpi, 

 the insect might be considered as Pyralidous. The neuration dif- 

 fers essentially, however, from that type ; the absence of ocelli and 

 the rounded secondaries are Geometridous characters. The anten- 

 nae are simple, scaled, provided beneath with longer and very fine 

 hairs in the male, in the female these are shorter, two on each of 

 the well-exposed joints; the caputal scales are massed about the 

 antennal insertion. 



Argyrophyes cilicoides, Grote. 



Pure white, shaded with smoky brown. Fore wings with a raised blotch of 

 black metallic scales at the extremity of the cell ; opposite and beyond this, 

 inside of the transverse line, are a few more scattered dark scales. The ter- 

 minal portion of the median space, on which the metallic blotch is placed, is
