NORTH AMERICAN LEPIDOPTERA. 205 



I have only females, and so am able to give no description of the 

 genitalia of the Z . Mr. Ragonot, in describing the genus, suggests 

 that vein 8 may sometimes be obsolete. From my s[)ecimens I do 

 not think this possible, as 8 is long, distinct and separate. 



1. R. dotalis Hulst, Trans. Am. Ento. Soc. xiii, 164, 1886 (Anerastia). 

 discigerella Eag.. Diag. N". A. Phyc. p. 17, 1887. 



Expands 26 mm. Palpi, head and thorax fuscous white, with a few scattered 

 black scales. Abdomen fuscous white, with a faint ochreous cast on the posterior 

 part of each segment ; fore wings and base ochreous, followed by light cinereous ; 

 first cross line blackish, running obliquely outward, strongly angulated at ante- 

 median space, edged with whitish on basal side, and that edged with a broad, 

 even, ochreous fuscous baud; middle field white, much peppered with black on 

 auterior half, the same with an ochreous shading on posterior half; discal spot 

 ochreous. annulated with black ; outer line oblique, somewhat angulated just 

 before middle, edged outwardly with whitish, and that with a band of same 

 width and color as the one within basal line ; outer space cinereous, inclosing a 

 subterminal black line; fringe cinereous; hind wings pellucid white, slightly 

 fuscous on anterior angle; fringe white; beneath, fore wings dirty white, with 

 afaint ochreous shade along costa on outer field, and broadly along inner margin ; 

 centrally fuscous; hind wings white, a little fuscous on anterior margin. 



Colorado, Arizona. 



2. R. sagauella n. sp. — Expands 32 mm. Labial palpi, head and thorax 

 light gray, heavily dusted with black scales. Abdomen light gray, somewhat 

 annulated with blackish, third and fourth segments ochreous; fore wing narrow 

 at base, costa quite straight; apex, outer margin, and outer angle rounded, inner 

 margin sinuous. Color even light gray, heavily marked with black, and some 

 stained with fuscous, the veins all black lined; lines almost obsolete, the first 

 evidenced by a white spot at inner margin, the outer by a lightening between 

 the black veins. Hind wings clear, shining, iridescent, very light fuscous, the 

 veins and margin darker. 



From T. D. A. Cockerell, of West Clifi', Col., where the unique 

 specimen was taken at light, May 24th. 



This insect is hardly congeneric with dotalis. The wings are dif- 

 ferently shaped, the tongue is much longer, being one-half as long 

 again as the palpi, and consequently it lies midway between JNIr. 

 Ragonot' s two subfamilies. 



MARICOPA n. gen. 

 (Type lativittella Rag.) 



This genus resembles Ragonotlu in palpal construction. The vena- 

 tion is also the same, except that there are but 7 veins in the hind 

 wings, vein 5 being absent. The male is not known, so the antennal 

 construction cannot be given.
