nervures; at the apex there are two very regulär rows of similar nervures; posterior 

 tibiae with one strong spine on each; underside more or less green (in fresh specimens

Soll nach Fowler dem F. hianeralis ähnlich sein, vielleicht eine Varietät dieser 

 Art, unterscheidet sich jedoch von dieser Art durch die mehr parallele Form und 

 glatteren Deckflügel und durch die Anordnung der Quernerven in der Costalmembran, 

 welche nicht so dicht und mehr unregelmässig sind. 



40. Atracis simillima Fowl. 



Flatoides simillimits Fowler, Biol. Centn Amer. Hom., p. 62, 7 (1900). 



Praecedenti (F. pollutus) maxime affinis, sed capite breviori, haud producto; 

 fronte etiam breviori, et tegminibus magis decumbentibus, brunneis, linea fusca sinuata 

 intra marginem costalem decurrente, aliaque latiori fortiter sinuata ante apicem, prae- 

 cipue distinguendus. 



A small species, very like the male of F. pollutus, but of a fuscous-brown colour, 

 with the head shorter and more truncate, and the fore-head, in consequence, shorter 

 and broader; the tegmina are more decumbent, and inside the broad costal margin there 

 is a sinuate fuscous hne continued from the base to near the apex; before the apex is a 

 broader, strongly sinuate, fuscous line, and there is a broad dark line near the claval 

 sutur; posterior tibiae unispinosae.
