March, 1906.] SMITH : NEW NoCTUIDiE. 13 



Ursogastra lunata, new species. 



Head and thorax reddish fawn gray, immaculate. Primaries of the same reddish 

 gray ; basal line geminate, marked by brown or blackish scales ; t. a. line geminate, 

 very oblique, reaching almost the middle of inner margin ; t. p. line geminate, broken, 

 obscure, even, a little outcurved over cell, then almost parallel with outer margin ; 

 s. t. line pale, defined by brown sca'es on each side, almost rigidly parallel with 

 outer margin. A series of small black terminal lunules ; a yellow line at base of 

 fringes. The ordinary spots are replaced by a large deep chocolate brown lunate 

 mark, the concavity toward the costa, and this forms at once the most prominent and 

 distinctive character. Secondaries dull smoky, with a darker discal spot and outer 

 shade band ; secondaries whitish, without marks. 



Expands. — i. 25-1. 30 inches = 26-28 mm. 



Habitat. — Huachuca Mts., Ariz., Dr. Barnes ; Palmerly, Cochise 

 Co., Ariz., in August, Brooklyn Institute Collection. 



Two somewhat defective males only are at hand. I cannot recol- 

 lect that I have ever seen this species elsewhere. 



Genus NOCLOA, new. 



Head of moderate size, retracted rather than prominent ; eyes naked, hemi- 

 spherical, without bristly lashes ; front protuberant, conical, obtusely terminated, with 

 a roughened impression at tip ; palpi moderately developed, reaching the middle of 

 front, terminal joint short and knob-like ; tongue moderately long, functional ; frontal 

 vestiture woolly, the hair somewhat flattened at tip ; antennae simple in both sexes. 

 Thorax well developed, quadrate, vestiture of flattened hair, loose and somewhat 

 diverging ; collar and patagia well marked ; a small frontal and somewhat well de- 

 fined, partly divided posterior tuft; vestiture of underside long, loose, divergent; 

 legs rather short, well developed, with hairy clothing, without spines, claws or other 

 armature except the usual spurs of tibia. Primaries rather short in proportion to 

 body, costa not very convex, outer margin obliquely arcuate ; venation normal to all 

 appearance. Secondaries proportionate, vein 5 weak, midway between 4 and 6. 



This genus resembles Cirrhophanus in habitus, but differs from it 

 and the surrounding genera to which I would have referred the species 

 by the unarmed fore-tibiae. 

 Nocloa plagiata, new species. 



Ground color a reddish luteous ; the maculation is red, brown or deeper tinted. 

 Head unicolored or with only a faint inter-antennal line ; collar brown tipped ; tuft- 

 ings a little darker than the ground. Primaries, basal line barely traceable, basal 

 space of the paler ground except for a dark brown spot on the inner margin. T. a. 

 line geminate, outer portion distinct, inner a mere line of brown scales, outwardly 

 oblique, dislocated on the costal vein, outcurved in the interspaces. T. p. line gemi- 

 nate, outer portion obscure, inner narrow, linear, a little denticulate in the upper 

 part of its course, widely outcurved over the cell, the included space a little paler 

 than the ground. The median space is as a whole the darkest part of the wing, 

 though not contrasting ; a median shade, best marked on costa and just below darkens
