General coloration of head, prozonal portion of pronotal disk and exposed 

 surfaces of femora cartridge buff, showing even more whitish in life than in 

 dried specimens. Head with two postocular bars on each side of velvety 

 black, the occiput necked and suffused with velvety black, particularly caudad. 

 Pronotum with prozonal portion of disk shading from cartridge buff to whitish 

 laterad, metazonal portion of disk chamois; lateral lobes with a suffused 

 metazonal band of velvety black dorsad, this individually extremely variable 

 in width, remaining portions chamois. Mesonotum and metanotum suffused 

 with black, the latter with a pale fleck on each side, which is usually con- 

 spicuous. Dorsal surface of abdomen honey yellow, the third and fourth 

 tergites suffused with black. Ventral surface chamois, becoming ochraceous 

 on caudal portion of sternum and on abdomen. Cephalic limbs cartridge 

 buff marbled with a tinge of black, this more decided distad on the cephalic 

 faces of the tibiae. Caudal femora cartridge buff, dorsal surface with a proxi- 

 mal fleck, a broad meso-proximal band, a weak medio-distal band and geni- 

 cular areas black; the heavier band is continued to the median line on the 

 external pagina, the weaker band invading that area only briefly, while 



9 In the species of this genus the ovipositor is carried with only the distal 

 portion projecting. When in active use, however, it is probable that this 

 organ can be fully extruded. Six specimens in the present series have been 

 dried with the ovipositor in that position. 



30 This specimen, though having the ovipositor fully developed, appears 

 to retain certain nymphal features.
