inclined to consider it. Mr. Bruce has, however, taken a number 

 of specimens at higli elevations, all of them alike, and has convinced 

 me that we have to do with a good species, which I take great pleasure 

 in dedicating to him. 



RANCORA n. gen. 



Eyes naked, with I'athcr sparse, hairy lashes. Front smooth, with 

 straight, projecting, scaly and hairy vestiture, forming rather well- 

 marked su[)erimposed tufts; between the antennie the vertex is 

 clothed with stiff, divergent hair. Tongue long, stout. Palpi short, 

 stout, very slightly exceeding the front. Antennte of the male with 

 conic serration.-, which are set with tufts of bristly hair. Thorax 

 robust, with hairy clothing forming a somewhat im])rominent poste- 

 rior tuft. The collar is rounded, somewhat prominent centrally, but 

 scarcely hood-like as in Cucullia. The legs are stout, clothed with 

 long hair, and the tibitie are not spinose. Primaries elongate with 

 pointed apices and oblique outer margin, yet scarcely lanceolate. 

 Secondaries rather small ; vein 5 much weaker than the others, and 

 from the cross-vein. Abdomen conic, that of the male well exceeding 

 the anal angle of the secondaries, and furnished with distinct, though 

 loose dorsal and smaller lateral tufts. 



The genus is related to Cucullia, from which it differs in the form 

 of the primaries, which are not lanceolate; in the collar, which is 

 not hood-like, and in the male antennie, which are serrate instead 

 of simple. It is not unlikely that Cuciillia serraticornis may be re- 

 ferred here ; but I have no sufficient number of specimens for 

 comparison, 



Raiicora strigata n. sp. {PI. i, row 1, fig. 1)— General color ash-gmv. 

 Head, with vertex, rather darker, and with a blackish transverse line helow the 

 antenna). A distinct black line at base of collar, which is tipped witii mouse- 

 gray. Thorax with the dorsum somewhat darker, becoming blackish posteriorly. 

 Abdomen mouse-gray. Primaries bluish ash-gray, all the veins black lined, the 

 median lines incomplete. The t. a. line is single, vaguely marked on costa, with 

 a distinct long outward tooth in the submedian interspace, and a shorter but 

 similar tooth below the submedian vein. A longitudinal black line extends from 

 the base through the submedian interspace to the apex of the tooth of the t. a. 

 lino and beyond that point less distinctly to the outer margin. The t. p. line is 

 faintly indicated on tlie costa and is obsolete beyond that until it reajjpears as a 

 lunate blackish mark in the submedian interspace, below which it runs, inwardlv 

 oblique to the inner margin. A series of blackish interspaceal streaks begins at 

 the apex, the marks increasing in length to the fourth from the apex, which 

 runs from the end of the cell to the outer margin; below this two marks are 

 short, the third running from the luuule of the t. p. line to the outer margin,
