DICHROMA ARCUALIS. 

 PLATE XXX. Fig. 3. 



Tue fore wings in this species are of a dirty and 

 rather pale brown colour, ornamented with white 

 markings ; near the base of the wing is a strongly 

 furcate mark, the anterior branch of which is di- 

 lated; parallel to the inner margin of the wing is a 

 white slender bar, which is connected near the 

 middle of the wing with a series of white crescents 

 placed obliquely, and extending upwards to the 

 middle of the wing, above which is a clavate spot ; 

 beyond this, and extending in an oblique direction 

 to the tip of the wing, is a strongly denticulated 

 white line ; and there is a row of white arches 

 along the outer margin of the wing, diminishing in 

 size as they extend towards the apical angle. The 

 hind wings and abdomen are white, slightly tinged 

 with brownish. 



The expansion of the fore wings is one inch.
