Dr. Herrich-SclirefFer. Korr. Blatt. d. zool. iiiin. Ver. in Regensburg, 

 1858, p. 153, would refer MicrococUa d'tphthcroides to Hiibner's genus 

 Mnma, I think incorrectly, the habitus of the species being very differ- 

 ent from that of the European Moma orion Linn., to which latter 

 species B./hUnx. H-8. and D. f/rsejii\ m., are more nearly allied. Sub- 

 sequently, Korr. Blatt. d. zool. min. Ver. I860, pp. 71 and 72, the 

 same distinguished authority, recognizing the validity of M. Gruenee's 

 genus GrammopJiOJ-a, would unite under the latter generic name the 

 species included under Microcoelia Gruen., regarding the two genera 

 as identical although placed by M. Guenee in different families. I incline 

 to believe this view correct, while I am as yet prevented, through paucity 

 of material, from making the necessary examinations to establish the 

 fact. M. vinnnhi. m., appears to me the link connecting the two series 

 of species, for, while showing the ornamentation of Microcoelia^ it has 

 much the habitus of Grammopltora hebrsea Guen.

Anterior wings purplish brown, basal and median spaces pale yellow- 

 ish, ordinary spots distinct, yellow, median lines geminate, dark brown- 

 ish. Basal line distinct ; sub-basal space dark purphsh brown ; trans- 

 verse anterior line sinuate ; median space large, pale yellowish, sprink- 

 led with purplish atoms ; orbicular spot rounded, distinct, yellow, with 

 a central brownish dot; claviform, rounded, large, distinct, divided in 

 the centre by a very faint brownish line. Reniform spot large, yellow, 

 with a central brownish line, sub-divided externally by brownish lines 

 into several smaller sub-spots. Transverse posterior line acutely pro- 

 jected below the eosta, oblique ; terminal and subterminal spaces pur- 

 plish browii very sparsely sprinkled with yellowish atoms ; subterminal 

 line obsolete, emerging from a large, pale, irregular, yellowish apical spot. 

 Posterior wings cinereous, immaculate. Under surface of both wings 

 cinereous with darker subterminal bands. Thorax and abdomen cinere- 

 ous, former slightly sprinkled with a paler shade. % S . Exp. 1^ in.

A delicate species with the habitus of G. nebris Gueuee. It differs 

 from the other North American species of the genus in that the ordi- 

 nary spots are of the same color as the median space, and not separated 

 into raised whitish dots, excepting only G. nitela Guenee, in which the 

 ordinary spots may be regarded as obsolete.
