37. Arphia simplex. Brownish fuscous. The general color 

 is very uniform, but the lower half of the head, and ^specially of 

 the face, passes to ashen ; lateral foveolae 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 pronotum are some- 

 times dotted irregularly with yellowish; pronotum 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 tibiae 

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