in lengtli distad, the very elongate distal segments divided into numerous 

 (eight to twelve) short and less strongly defined joints. Pronotum smooth, 

 length about one and three-quarters times width, longitudinal and transverse 

 sulci very weak. Mesonotum as given in generic description; carinae of proxi- 

 mal medio-longitudinal sulcus and cingulate lateral margins polished, all 

 finely and irregularly impresso-punctulate. Tegmina short, margin of lateral 

 field broadly convex; dorsal field truncate distad, angle at the sutural margin 

 very slightly the more produced, distal margin nearly transverse, very feebly 

 convex. \\'ings fully developed, extending to base of seventh dorsal abdominal 

 segment. Dorsal abdominal segments elongate to seventh, which is much 

 shorter, about as long as wide; eighth slightly longer, widening distad. Ninth 

 (distal) dorsal abdominal segment ascendant and somewhat tectate proximad 

 for a distance equalling the length of the preceding segment, thence, due to 

 the great production of the disto-ventral portions, furcate, the arms tapering 

 strongly in proximal portion, due to the declivity of the dorsal margin, thence 

 slender, produced to their sharply rounded apices which touch on their inner 

 faces, internal surface of these arms supplied with minute short hairs and 

 thickly armed with minute chitinous denticulations. Cerci elongate, straight 

 to their bluntly rounded, incurved apices. Subgenital plate short, slightly 

 shorter than eighth dorsal abdominal segment, free margin convex, except in 

 distal portion where it is bilobate. Limbs as given in generic description. 

 Arolia present.

 tegmen, 3.8; wing, 32.8; ninth (distal) dor.sal abdominal segment, 3.2; cercus, 

 2.3; cephalic femur, 12.6; cephahc tibia, 11.7; caudal femur, 10.3; caudal 

 metatarsus, 2.1 mm. Width of head, behind eyes, 2.1; dorsal field of tegmen, 

 1.8; lateral field of tegmen. 1.2; abdomen before apex, 1.2; abdomen at widest 

 (distal) point, 1.7 mm. 



Head light browaiish olive; with two narrow, longitudinal, i)ostocular bands 

 on each side of cinnamon-buff margined with sepia, of which the ilorsal band 

 is the widest; face and mouthparts cinnamon-buff. Antennae walnut brown 

 proximad, each joint beyond the first two deepening to blackish brown distad, 

 very elongate distal joints gradually becoming paler distad, the more distal 

 with proximal portion light buff, the distal portion suffused, shading to walnut 

 brown at apex. Pronotum and mesonotum light brownish olive, lateral 

 carinae of latter cream Ijuff. Tegmina walnut brown, the veins slightly paler; 

 intermediate field paler, cacao brown; areas between veins suffused with burnt 

 umber toward sutural margin in dorsal field, .\nterior field of wings rood's 

 brown, excey)t along the caudal margin where it is i)inkish buff heavily and 

 irregularly maculate with longitudinal markings of burnt uml)er; radial field 

 transparent, avellaneous. Mesosternum ochraceous-buff, suffused with rood's 

 brown mesad. Metapleura and metasternum rood's brown, the soft integu- 

 ment between these portions buffy. Abdomen cinnamon above, clay color 

 below; the fourth, fifth and sixth dorsal segments with two pairs of small 

 l)lackisli I)rown flecks, of wiiich those of the cephalic pair are the largest and 

 less widely spaced. Limbs ochraceous-butT, the extreme tijjs of the femora
