Sparganothis umbrana, n. sp. PI. XX\'III, Fig. 3. 



Labial palpi dark reddish brown. Face naked. Head and thorax light 

 reddish brown. Forewings light ochreous with golden and greenish iridescence 

 and with dark brown markings; an ill-defined, narrow, reddish brown fascia 

 from before the middle of costa to just beyond the middle of dorsum; an apical 

 dark brown area occupies the outer third of the wing and is sharply outlined 

 against the lighter ground color of the basal two-thirds, which terminates before 

 apical third of costa and bulges outwards shortly below the costa into the 

 darker apical part of the wing; a small reddish brown spot on the fold near 

 the base. Cilia light ochreous. Hindwings dark fuscous brown with light 

 ochreous cilia. Abdomen dark ochreous with lighter underside. Legs ochreous 

 with tarsal joints faintly annulated with fuscous.

A somewhat variable species, closely allied to the very variable 

 Californian species 5". scuccionana Walsingham, which I consider only 

 a variety of riidana Walsingham and of the iminaculate incoiiditana 

 Walsingham ; in a very large series before me these forms grade into 

 each other so completely, that I can only consider them all one species, 

 as many genitalia slides of the various forms seem to support. The 

 present species differs in having much longer labial palpi than the 

 Californian species, which must bear the first Walsingham name, in- 

 coiiditana. 



Platynota iridana, n. sp. 



Labial palpi reddish brown, mottled with black. Head and thorax reddish 

 brown. Forewings of the female reddish brown with a darker brown indistinct, 

 outwardly oblique facia from before the middle of costa to before tomus ; 

 another blackish brown fascia, broad on the apical third of costa becomes 

 attenuated and stops before it reaches tornus ; on both sides of this last dark 

 fascia are narrower light reddish outwardly oblique and curved fasciae which 

 are heavily overlaid with iridescent and silvery scales ; extreme terminal edge 

 and apex dark brown ; at the end of the cell a conspicuous black dot. In the 

 males the costal fold reaches to apical third of costa, broad on basal half and 

 narrow outwardly; basal two-thirds of the wing heavily overlaid with dark, 

 blackish brown scales, contrasting with a light ochreous transverse space at
