554 : Mr. R. E. Turner on the 
the base of the mandibles by a distance distinctly greater 
than the basal breadth of the mandibles. Pronotum produced 
into a distinct acute spine on each side ; mesonotum shining, 
sparsely punctured, notauli deep and crenulate. Median 
segment with an elongate and rather narrow median area, 
which is bordered by a transverse carina a little before one- 
third from the apex of the segment, the basal portion of the 
area narrowed from the base and strongly contracted at about 
one-third from the base, the apical portion (or areola) elongate- 
ovate, truncate at the apex, petiolar area broader than long, 
lateral carinze well marked; spiracles small and rounded ; 
sides of the segment rugose, produced into a short spine on 
each side at the apical angles. Abdomen opaque, the dorsal 
surface very finely and closely punctured-granulate ; the first 
seement petiolate at the base, about three times as long as its 
apical breadth; second and third tergites with an oblique 
sulcus on each side from the base to the middle of the lateral 
margin, and also with an indistinct curved depressed line on 
each side from the middle of the base to the middle of the 
lateral margin. Nervulus slightly prefureal; second re- 
current nervure strongly curved outwards and joining the 
cubitus distinctly beyond the transverse cubital nervure ; 
nervellus elbowed and intercepted close to the middle.

Closely allied to X. abaddon, Morley, from Assam, but 
differs in the colour, especially in the broad interruption of 
the white of the outer orbits and the apically black median 
segment, in the narrower first abdominal segment, and in the 
much less strongly impressed second and third tergites.
