 palporum articulus 3us apice piceus el oblique Iruncalus ; prothorax 

 antice angustior ; abdomen piceum ; cerci fulvi, abdomine non brevi- 

 ores ; oviductns testaceus, apice niger, corpore vix brevior ; pedes 

 longiusculi, femoribus posticis fusco substrigatis, tibiis posticis 

 utrinque serratis et quadrispinosis ; ales anticce pallide testacece, abdo- 

 men longe superanles, incondite reticulalte, venis longitudinalibus sub- 

 rectis, carina laterali nigricante punctata; alee posticce longiores.

 blackish. Eyes slightly prominent, partly blackish near the hind border. 

 Third joint of the palpi piceous towards the tip, which is obliquely truncated 

 and excavated. Antennae very slender, about twice the length of the body. 

 Prothorax not longer than broad, a little narrower in front. Abdomen 

 shining, piceous. Cerci tawny, as long as the abdomen. Oviduct testa- 

 ceous, with a black tip, nearly as long as the body. Legs rather long ; hind 

 femora obliquely and indistinctly streaked with brown on the outer side ; 

 hind tibiae minutely serrated and with four rather slender spines on each 

 side. Fore wings pale testaceous, extending much beyond the tip of the 

 abdomen, with blackish dots along the externo-medial vein, irregularly 

 reticulated between the nearly straight and parallel longitudinal veins ; 

 apical triangle pale cinereous. Hind wings pale cinereous, extending 

 much beyond the fore wings ; costa and veins pale testaceous. Length of
