Zaspilothynnus ohliquestriatus, sp. n. 



S . Niger ; clypeo convexo, sparse punctate, apice late truncato ; 

 hypoitygio triangulari, angulis basalibus tuberculatis, apice spina 

 armato ; clypeo, mandibulis, marginibusque oculorum flavis ; alis 

 flavo-hyalinis, nervulis nigris. 



5 . Nigra, nitida, sparsissime punctata ; capite convexo, loiigitudine 

 latiore ; abdomine segmento primo oblique striate, scgmento 

 secuudo transverse sex-cariuato ; pygidio oblique truncato, lati- 

 tudine fere duplo longiore, obscure longitudinaliter striate. 



Long., S 18 mm., 5 11 mm. 



(J . The clypeus is very strongly convex, the apical margin 

 depressed and broadly truncate. Head, thorax, and median 

 segment closely and finely punctured, the pubescence on the 

 head and pronotum fulvous, on the median segment grey. 

 Abdomen narrowed a little at the extremities, shining, 

 more sparsely punctured than the thorax ; sixth ventral 

 segment with a spine on each side at the apical angles ; 

 seventh dorsal segment produced into a flattened plate, 

 coarsely punctured and truncate at the apex ; hypopygium 

 triangular, distinctly longer than the breadth at the base, 

 with a stout apical spine, the basal angles with a well- 

 developed tubercle. Third abscissa of the radius a little 

 longer than the second ; first recurrent nervure received 

 beyond two-thirds from the base of the second cubital cell, 

 second just before one-third from the base of the third 

 cubital cell. The groove between the first and second ventral 

 segments is not deep. The carina between the antennae is 

 almost transverse ; abdominal segments feebly constricted at 

 the base. 



2 . Mandibles falcate, acute at the apex ; head about half 

 as broad again as long, strongly rounded at the posterior 

 angles, moderately convex ; front rather closely punctured 

 above the base of the antennae, with a short longitudinal 

 sulcus ; the vertex shining, with a few scattered punctures. 

 Thorax and median segment shining, with a few shallow 

 punctures ; pronotum subrectangular, more than half as 

 broad again as long, the posterior margin arched ; scutellum 

 broader than long, broadly rounded at the apex ; median 

 segment only half as long as the pronotum. First abdo- 

 minal segment strongly obliquely striated, second segment 

 with six strong and even transverse cariuae ; segments 3-5 

 shining, with a few scattered punctures. Pygidium obliquely 

 deflexed, about twice as long as broad, the sides parallel, 

 indistinctly longitudinally striated, with a tuft of fulvous
