Dark yellowish brown, profusely mottled and flecked with grayish 

 cinereous, the dark color generally predominating, and sometimes becom- 

 ing black on the summit of the head, the sides of the pronotal crest, and 

 in a couple of short longitudinal stripes along the anterior half of the 

 lateral lobes of the pronotum; the hinder edge of the pronotum is usually 

 alternately pale and dark; antenna? dusky, yellowish brown at the base, 

 and annulate with yellowish brown for some distance beyond it; tegmina 

 mottled with dark cinereous and blackish-brown, the latter most con- 

 spicuous in an agglomeration of these spots just before the middle, half 

 way between that and the base, and at an equal distance beyond the 

 middle band; the apical fourth of the wing is obscurely subhyaline, oc- 

 casionally with a slight concentration of dark spots at the tip; the lighter 

 colors predominate along the costal margin on either side of the median 

 dark patch. Wings light greenish-yellow at the base, sometimes tinged 

 to the least possible degree with saffron (more noticeable in the closed 

 wing) , with a moderately broad, blackish fuscous, arcuate mesial band, 

 at the costal border (but omitting the costal edge), extending abruptly a 

 short way toward the base of the wing; beyond this band the wing is 

 hyaline with blackish fuscous nervures, some of the cells near the tip 

 partially or wholly fuliginous fuscous, forming a more or less marked 

 infuscation. Hind tibiae coral red, the extreme base black, followed by a 

 more or less distinct pale annulation. Crest of pronotum exceedingly 

 high, arched pretty regularly, the hinder extremity of the anterior lobe 

 sometimes overlapping the front of the posterior lobe; the posterior 

 border of the pronotum very acutely angled. 



Length of the body, male 26.5 mm., female 36.5 mm.; of antenna?, male 

 13.5 mm., female 14.6 mm.; of tegmina, male 30.25 mm., female 36 mm.; 

 of hind femora, male 16 mm., female 20 mm.
