LAM PR A V ORB ESI, sp. nov. 



LAMPRA FORBESI, n. sp. 



Ground color variable, but dull; often smol.y gray, sometimes witli 

 a reddish tinge. Head, collar, thorax, and ground color of primaries con- 

 eolorous. In the gray sj^ecimens the i)ody is also concolorous; in the red- 

 dish ones, of the same .shade as the base of the secondaries. Ordinar}' 

 spots distinctly outlined by a clear, light, ochreous line, and similar to 

 nefascia. Orliicidar with a tendency to minuteness as in dnanca and filled 

 with ground color. Terminal area of primaries paler than ground, with 

 a slight blueish cast; s.t. area slightly darker, especially at the costa, which 

 is marked with black points at the l)asal, t.a., and t.p. lines. Primaries 

 shaped much as in alternata; but finely and smoothly scaled, giving the 

 wings a silky luster. More or less of a scattering of black scales over the 

 ])rimaries. Palpi black at the sides, lighter at the tips. Antennae mi- 

 nutely ciliated, with longer setae from each joint. Thorax apparentlj' 

 .smooth, but on careful examination with the barest trace of a spreading, 

 divided, crest. In most specimens this cannot be seen. Tip of the ab- 

 domen of male relatively broad; of female almost truncated and much 

 depressed. The peculiar heavi/ ribbing of the jjenis separates it immedi- 

 ately from all other species in the genus.
