MORGAN HEBARD 8 1 



distinctly convex; lateral margins very feebly cingulate; greatest width meso- 

 caudad; caudal margin transverse, but showing a broad and weak convexity mesad. 

 Tegmina and wings broad and reaching slightly beyond the cereal apices; venation 

 as characteristic of the genus, veins numerous (ulnar vein of wing with five com- 

 plete and seven incomplete branches). Sixth dorsal abdominal segment with 

 latero-caudal angles sharply rectangulate, not produced caudad; seventh segment 

 with a heavy rounded chitinous projection laterad on each side; eighth segment 

 simple. 



Supra-anal plate rotundato-trigonal produced between the cerci, length distinctly 

 less than half the basal width, less strongly chitinous toward apex with free margin 

 supplied with hairs. Subgenital plate very ample, strongly convex; free margin 

 convex, flattened toward cerci, narrowly curled dorsad in median portion, this 

 brief area showing a medio-longitudinal cleft or sulcation. Limbs and armament of 

 same as characteristic of the genus. Four proximal caudal tarsal joints supplied 

 disto-ventrad with moderately large rounded pulvilli. Arolia small. 



Head immaculate ochraceous-tawny, eyes blackish mummy brown. Ocelli 

 and proximal antennal joint pale ochraceous-tawny, antennae cinnamon brown. 

 Maxillary palpi pale ochraceous-tawny, the distal joint ochraceous-tawny. Pro- 

 notum immaculate zinc orange tinged with tawny, deepening slightly to tawny 

 along caudal margin. Tegmina translucent, tawny, except costal field which is 

 ochraceous-bufY with feebly cingulate margin tawny. Wings transparent, with a 

 faint tawny tinge, except in area of costal veins where they are tinged with buffy, 

 becoming weak tawny in entire distal portion of anterior field. Mesonotum, meta- 

 notum and dorsal surface of abdomen ochraceous-bufT, shading to dull ochraceous- 

 orange in distal portion of abdomen. Cerci cinnamon brown. Ventral surface of 

 abdomen tawny, deepening to russet on subgenital plate. Limbs ochraceous-tawny, 

 deepening to tawny on tibiae and tarsi. 



Length of body, 22.5; length of pronotum, 5.9; width of pronotum, 7.8; length of 

 tegmen, 21 ; width of tegmen, 6.8; length of wing, 18.8; depth of wing, 12; length of 

 caudal tibia, 8.2; length of cercus, 3.9 millimeters. 



In addition to the type, two immature examples, taken at Porto 

 Bello, Panama, February 28, 191 1 and April 20, 1912, by Busck, 

 are before us. These have the head, pronotum and cerci sanford's 

 brown, the remainini^ portions blackish chestnut, the tarsi dis- 

 tinctively marked with buffy in a very broad annulus on the 

 metatarsus and the proximal portion of the ultimate tarsal joint. 

 Their length is 10.2 and 12.4 millimeters respectively.
