minal space is whitish, powdery. There is not, in the specimens ex- 
amined by me, any*black dash opposite anal angle. 
Electilis, if a Dicopis at all, belongs to this series and stands next 
to muralis, to which Mr. Morrison makes it “ distantly ” related. 
Viridescens W1k. is also probably a very near relative of muralis. 
In synoptic form the species known to me autopically, are as folows: 
A black dash in terminal space opposite anal angle. 
Blackish, vestiture rough; lines incomplete, not well marked, reniform contrast-

Head and thorax blackish or deep dark brown. A little tuft at base of antennez 
whitish. Disk of thorax quite densely, of patagie sparsely white powdered, the 
latter with a black submarginal line. Primaries blackish or dark smoky gray, with 
mossy green shadings, unequally and somewhat inconstantly distributed over the 
‘surface. T.a. line geminate, black, outwardly oblique, irregular, variably distinct. 
A curved black basal dash looped beyond the t. a. line to form a broad claviform. 
Over this streak and in the claviform the wing is sometimes more or less white pow- 
dered. T. p. line geminate, black, irregular, fairly distinct, widely onteurved over 
the reniform, then deeply indrawn, touching the reniform inferiorly, reaching the 
inner margin opposite the space between the ordinary spots. A blackish median 
shade between the ordinary spots reaching the inner margin at about its middle. 
Beyond this shade extends a white blotch along the inner margin becoming blnish 
beyond the t. p. line, which is here emphasized and brought out prominently. S. t. 
line broken, irregular, mossy green or yellowish, with a deep inward sinus on vein 2, 
below which it is prominent and on which it is crossed by a black dash. Veins 
more or less evidently black marked. A broken terminal black line marked by blue 
powderings around the veins. Orbicular round, moderate in size, concolorous, with 
a whitish central dot and a whitish annulus which are sometimes indistinct. Reni- 
form large, diffuse, usually white, contrasting. Secondaries white, black powdered 
on the veins and over the outer margin beyond a broken extra median line. Discal 
spot of underside visible above. Beneath soiled white with variably diffused black 
powderings, most obvious on the primaries. A more or less obvious outer line and 
distinct discal spot on all wings. 
Expands 39 to 41 millimetres = 1.56 to 1.64 inches.

Six specimens are in the Museum collection (Acc. 20395 and collec- 
tion of O. Meske), from which the above description was made. The 
antenne are yellowish. The color varies considerably in intensity, 
and fresh specimens have the mossy green tint most distinct. The 
transverse lines are not usually all traceable, while the large indefinite 
discolorous reniform is always evident and usually prominent, contrast-
