1 cf from Mt. Murud (6500 feet) and 1 9 from Mt. Dulit. 



This new species comes in my key (Treubia, v, 1 — 3, pp. 110 

 — Ill) very near to the Sumatran X. hehardi, and agrees there- 

 with by the strong cross veins of tegmina, the yellow length 

 stripes on pronotum, by the shape of cT anal segment, and by 

 the extraordinarily short ovipositor. It differs, however, from 

 X. hehardi by the shape of cf subgenital plate. 



By the enumerated characters it may be distinguished from 

 all the hitherto known X. phidiopsis-species, and thus it can 

 also not be mistaken for one of the Malayan species recently 

 described by Hebard (Proc. Nat. Sci. Philad., Ixxiv, 1923, 

 p. 253 ff.). — These differ at the first view by the entirely other- 

 wise shaped cf genitalia.
