Pezotettlx arkansana McNeill!, MS. 



Of tolerably larf;e size, brownish yellow. Head a little ]>ronunent, 

 luteo testaceous; a broad dark brown or blackish median band extends 

 from the vertex between the eyes to the posterior extremity of the 

 l)ronotuni, broadest on the latter and occupying about one third of it, 

 but sometiiui's, and especially in southern examides, wholly absent 

 from the p'onotuin; besides this, another band runs from behind 

 the eye to ijhe anterior margin of the metazona; generally this is 

 comi)arativ^ly narrow and often obscure, but often sends otf streaks 

 of blackish fuscous down the incisures, and is sometimes tolerably 

 4listinct and uniformly deep in tint; vertex cimsiderably tumid, well 

 raised above the level of the pronotum, the interspace between the 

 eyes fully half as broad again ( male) or more than twice as broad 

 (female) as the tirst antennal Joint; fastigium strongly declivent, 

 slender, with i)arallel sides, and rather deeply sulcate; frontal costa as 

 broad as the interspace between the eyes, e^iual, scarcely sulcate below 

 the ocellus, biseriately punctate above; eyes large, not very prominent 

 even in the male, elongate but no longer than the infraocular portion of 

 the genae; antennae yellow, somewhat infuscated apically, fully three- 

 tourths (male) or but little more than two thirds (female) as long as the 

 hind femora. Tronotum slightly expanding posteriorly, the disk 

 broadly convex and passing by a well rounded sh<mlder, which only 

 l)osteriorly forms the semblance of lateral carinae, into the vertical 

 lateral lobes; median carina scarcely perceptible except on the meta- 

 zona, where it is distinct but not prominent; transverse sulci distinct;
