a broad band of darker brown crossing the tegmina, when at rest, 

 in their meso-distal portion. We know of no other species of sim- 

 ilar coloration. 



Type. — cf ; Gatun, Canal Zone, Panama. (A. H. Jennings.) 

 [United States National Museum.] 



Supplementing the generic features here given, we would note the following for 

 this species. Interocular space approximately two-fifths as wide as that between 

 the antennal sockets. Maxillar\' palpi with third and fourth joints subequal in 

 length, each about twice as long as interocular width, fifth joint small, enlarged, 

 slightly over half as long as fourth joint. 



Pronotum broad oval, with cephalic margin moderately flattened and caudal 

 margin broadly flattened, showing a very feeble convexity. Tegmina very elongate, 

 the median third with margins parallel, the sutural margin showing the greater 

 convergence distad, the rather sharply rounded apex slightly nearer the costal 

 margin; discoidal sectors (seven) regular. Wings moderately broad; the moder- 

 ately elongate costal veins with distal half moderately enlarged, the clubs (seven) 

 resultantly very elongate; ulnar vein with (four) complete branches, these and the 

 discoidal and median veins connected by weak transverse veinlets; intercalated 

 triangle over half as broad as long. 



Supra-anal plate with length approximately two-fifths ]:)roximal width, triangu- 

 larly produced, rectangulate emarginate distad, the apices thus formed broadly 

 rounded and supplied with a few long hairs, as is the distal portion of the abdomen 

 and the cerci. Cerci with (eleven) distinct joints, each with lateral margins con- 

 vex, this convexity sharp proximad and distad beyond the proximal segments 

 except in the apical segment which is slender and cylindrical; dorsal surface of 

 cercus feebly convex, ventral surface with segments moderately convex and strongly 

 cingulate laterad. 



Concealed genitalia: the paired plate beneath the supra-anal plate is reduced, 

 very delicate, the caudal face of each half convex; the remaining organs within the 

 anal chamber are withdrawn and can not be seen in the type. 



Subgenital plate scoop-shaped, symmetrical; lateral portions vertical, margins 

 straight, parallel, weakly declivent, distad rounding broadly ventrad into distal 

 two-thirds of free margin which is transverse, with a small rounded ridge on each 

 side dorsad, each occupying one-third of this section of the free margin; from sockets 

 at the angles formed by the lateral and mesal portions of the plate spring the similar, 

 heavy, cylindrical styles, directed dorsad and feebly caudad, three times as long as 

 wide, their apices subchitinous dorso-caudad, each supplied dorso-cephalad with 

 two minute uncinate teeth which curve over the soft areas. 



Head shining, ochraceous-buff ; eyes and a broad interocular band blackish brown. 

 Limbs and spines immaculate ochraceous-buff. Ventral surface of abdomen shin- 

 ing blackish brown, except narrowly proximo-laterad where it is ochraceous-buff. 

 Pronotum shining; disk ochraceous-tawny with three very inconspicuous pairs of 

 darker flecks, lateral margins transparent faintly tinged with brown. Tegmina 

 transparent, faintly tinged with brown except in penultimate fifth, where the areas
