two faintly indicated large basal obconical spots, base of lateral margins, and cruciform elevation at base 
yellow. Anterior margins of tympana, lateral margins of first, second, and fifth, and basal margin of 
sixth abdominal segment creamy white. Underside of body much paler, and covered with whitish

The opercula are pale, not passing the base of the first abdominal segment ; their apices are broad and rounded ; 
and their inner margins considerably overlap. The face is moderately convex, thickly pilose, and with the 
sides strongly and transversely striated. The anterior femora are armed with two long acute spines. 
Long. 20 millim., exp. tegm. 52 millim. 
Hab. Mexico (Mus. Berol.). 
I originally considered this species the C. alacris, Stal; but since then, from an 
examination of Stal’s type, I have found his species to be a synonym of C. transversa, 
Walk.; and I have therefore been compelled to provide this insect with a fresh 
hame.
