the middle area, with blackish and whitish fleckings, generally dis-

 est possible cloudiness at the extreme tip; legs brown, flecked, and 

 the fore and middle pair delicately subannidate, with blackish ; hind 

 tibias dull yellowish, edged beneath with blackish, the apical half 

 of the spines black. Abdomen dull ferruginous, slightly paler be-

37. Arphia simplex. Brownish fuscous. The general color 

 is very unilbrm, but the lower half of the head, and especially of 

 the face, passes to ashen; lateral foveolas of the head scarcely distin- 

 guishable from the parts below, the lower limits being very obscurely 

 marked. The edges of the lateral lobes of the pronotuni are some- 

 times dotted irregularly with yellowish; pronotuni somewhat sca- 

 brous ; pronotal crest not high nor arched, uniform ; tegmina flecked 

 with fuscous dots pretty uniformly distributed over the whole, except- 

 ing in being a little crowded in the basal half of the middle area ; 

 wings at base red, with a slight orange tinge, bounded by a moderately 

 broad, nearly equal, arcuate, dark fuscous band, passing from the mid- 

 dle of the outer half of the costal border nearly at right angles to 

 the same, until it reaches the opposite border, when it curves inward, 

 following the border more than half way to the anal angle ; it sends 

 inward fully half way to the base of the wing, a broad, generally 

 tapering shoot just below the costal margin ; beyond the arcuate 

 band the wing is fuligino-pellucid, and at the tip fuliginous, all the 

 veins dusky; hind femora very indistinctly transversely trifasciate, 

 with an indistinct pale annulus just before the tip, the hind tibia3 

 obscure glauco-plumbeous, with a pale annulus next the base.

 antennae greyish - cinereous more or less dusky at base, beyond
