The above is Mr. Grote's description ; the only specimen at hand 

 (a 9 ) is somewhat rubbed and agrees fully with Grote's characteri- 

 zation. Mr. Grote elsewhere corrects his generic reference stating 

 that the collar was normal and not as above described.

 Head, thorax and primaries bluish ash gray. Primaries with basal line not 

 traceable. T. a. line regularly curved outwardly, single and not very definite, 

 marked rather by the somewhat darker median space. T. p. line incurved from 

 the costa, cutting the inferior portion of reniform and narrowing the median 

 space. Claviform wanting; orbicular well sized, black ringed, and with a black 

 centre, else concolorous. Eeuiform moderate in size, incompletely ringed, stained 

 with reddish; a distinct, somewhat diffuse median shade, crossing the centre of 

 the space through the orbicular. S. t. line pale, irregularly interrupted, preceded 

 and followed by irregular and not very definite blackish marks and shades; a 

 series of black terminal lunules ; a white line at the base of the otherwise con- 

 colorous fringes. Secondaries whitish, with an indefinite, smoky outer border. 

 Beneath, primaries smoky, somewhat pale powdered outwardly. Secondaries 

 white, outwardly smoky, very much as above. Expands 1.12 inches; 28 mm.

This species seems rare, and I have seen the 9 type only from 

 Mr. Tepper's collection. It is extremely close to occata in all respects, 

 the difference being chiefly in the larger orbicular and stained reni- 

 form. The median space also is not so dark.
