black, with the mesopleurse sinuately sulcate and subgiabrous 

 centrally ; the prosternum, mesosternum basallv below, a broad 

 hamate mark on either side of front of mesonotum and parallel 



with its disc, callosities 

 before and beneath radices, 

 and a large irregular mark 

 on metapleurte, stramineous; 

 metanotum with no costae but 

 laterally longitudinally sul- 

 cate above the pale mark 

 and below the elongate and 

 somewhat large spiracles, 

 Abdomen nitidulous and 

 very strongly compressed 

 throughout ; black, with 

 apices of all the segments, 

 and base of the first three 

 broadly, flavous ; basal seg- 

 ment thrice as long as apic- 

 ally broad and sublinear, 

 with the spiracles but slightly 

 before the centre, and thence 

 parallel-sided, a little broader and subcanaliculate to apex ; 

 terebra straight, slender and slightly longer than abdomen. Leys 

 flavescent, with hind femora fulvous ; hind legs with apical half 

 of coxae, apices and extreme base of femora and tibiae, quite black ,. 

 posterior onychii infuscate ; hind calcaria unequal, front ones 

 short and sinuate. Wings eutirely hyaline, ample but not broad, 

 with radix and tegulae stramineous, costa and stigma piceous ; 

 areolet subpetiolate, higher than broad, and emitting the uni- 

 fenestrate recurrent nervure from hardly before its apex ; first 

 recurrent of hind wings distinctly postfurcal, emitting the curved 

 nervellus from hardly below its centre. 

 Length 32 millim. 



SIKKTM, iv.-vi. 1900 (Col. Bingliam}. 

 Type in the British Museum. 



The strongly compressed abdomen gives this species a very 

 striking superficial resemblance to the Xorid genus Tropistef, but 

 the conformation of the head, areolet and elongate legs is very 

 distinct. 



Described from two females.
