Pjson (Parapison) tenebrosum, sp. n. 



5 . Mandibles acute at the apex ; clypeus sliort, more than 

 twice' as broad as long, narrowly convex or siibcarinate in the 

 middle, with a small blunt tubercle just before the apex, sub- 

 truncate at the apex, clothed with short silvery pubescence. Head, 

 thorax, and abdomen opaque : the eyes narrowly and shallowly 

 emarginate, separated on the clypeus by a distance about one- 

 quarter greater than that separating them on the vertex. Antenna; 

 scarcely longer than the head, inserted a little further from each 

 other than from the eyes, the scape as long as the first two joints 

 of the flagellum combined ; the first joint of the flagellum two- 

 thirds of the length of the second, the second and third almost 

 equal. Posterior ocelli twice as far from each other as from the 

 eyes. Pronotum almost straight, transverse, about three-quarters 

 of the breadth of the head ; mesonotum with a broad, shallow, 

 longitudinal, median depression not reaching the posterior margin. 

 Median segment a little shorter than the mesonotvnn, narrowed 

 from the base, obliquely truncate posteriorly, with a longitudinal 

 carina from the base lying in a shallow depression and not 

 reaching the apex, obscurely obliquely striated ; the face of the 

 truncation minutely and very closely punctured, with a deep 

 median sulcus. The sides and apical margin of the abdominal 

 segments with sparse grey pubescence. The first segment suli- 

 truncate at the base, nearly as long and broad as the second. 



Black ; the mandibles dark ferruginous ; the spines of the tibia; 

 testaceous ; the tegula?, the anterior tibia?, and the tarsi fuscous. 

 Wings hyaline, nervures fusco-ferruginous. 



The second cubital cell is small, triangular, pointed on tlie 

 radial nervure, less than one-third of the length of the first on 

 the cubital nervure, receiving the second recurrent nervure near 

 the base. The first cubital cell receives the first recurrent nervure 

 beyond two-thirds from the base. 



Length 5 mm., exp. 8 mm.

PisoN (Parapison) caliginosum, sp. n. 



5 . Mandibles short and veiy^ broad, shallowly and widely 

 emarginate at the apex. Clypeus half as broad again as long, 

 very feebly convex, strongly rounded at the apex. Head and 

 thorax opaque, very minutely and closely punctured ; the antennae 

 inserted almost as near to each other as to the eyes, the scape about, 

 equal in lengtli to the first two joints of the flagellum, the second 

 joint of the flagellum more than half as long again as the first and 

 a little longer than the thiixl. The emargination of the eyes 

 exceeding in depth the length of the first joint of the flagellum ; 

 the eyes at the base of the clypeus nearly half as far again from 

 each other as on the vertex. Posterior ocelli nearer to each other 

 than to the anterior ocellus, but nearer to the eyes than to each 

 other. Pronotum not more than two-thii'ds of the breadth of the
