here associated with one of the lower genera, which, although 

 higher than Dioptis, still, by its weak body parts and especially 

 by its slight abdomen and the mealy squamation of the latter, 

 evinces a sensible degradation from the firm body crust and 

 concentrated characters of the more typical genera of the 

 Family. M. regnatrix, is the third Cuban species of the genus 

 described ; the two formerly known being M. famosa, Grote, 

 and M. geometroides, Walker, The analogies of Melanchroia 

 with the Phalaenidae would be indicated by the name given 

 to this latter species by Mr. Walker ; these are, however, more 

 truly taken from the Bombycidae.

2 . Pale yellowish ochreous. Head, thorax, and legs, whitish 

 ochreous ; antennae simple, whitish ; legs slight, hind tibiae with 

 short spurs. 



Anterior wings a little rounded along costal margin at base, 

 depressed sub-apically ; apices truncated ; external margin broadly 

 produced above the middle. External margin of secondaries 

 broadly produced about the middle. Primaries pale ochre yellow 

 sparsely and irregularly irrorate with brown scales. A broad 

 arcuate, brownish black, transverse anterior band. A sub-obsolete 

 discal spot. A very broad, prominent, angulated, blackish brown 

 transverse posterior band, distinctly margined on either side. This 

 is twice bent or angulated : first, immediately at costa ; secondly, 

 opposite the disc. A faint, whitish, diffuse, sub-terminal shade. 

 Immediately below the apices, the external margin, which is here 

 excavate, is edged with brownish scales. Secondaries, whitish ochre- 

 ous, paler and more thinly scaled than primaries, tinged with a more
