broadly and the palpi white. Front and vertex closely, strongly and 

 uniformly punctured and sparsely covered with short pale hair. 

 Mesonotum closely and finely punctured and thickly covered with 

 short fuscous hair. Scutellum with a black mark, rounded above on 

 the apex ; the basal depression wide, deep and stoutly keeled 

 laterally. Median segment closely punctured all over and, except at 

 base, thickly covered with long fuscous hair ; the basal area is wider 

 than long and has oblique sides ; the posterior median area slightly 

 hollowed and not clearly limited, the keels not being very distinct ; 

 it is closely transversely striated. The upper part of the propleurfe 

 weakly punctured, the apex below stoutly transversely striated. 

 Mesopleura3 closely and strongly punctured ; in the middle above 

 is an oblique shining furrow. Mesosternal furrow wide, deep and 

 with some stout keels in the middle. Metapleurje closely punctured ; 

 the lower half of the basal depression with three stout keels. Apex 

 of petiole aciculated and marked Avith large, closely separated, punc- 

 tures ; the basal third of the 2nd segment is closely and strongly 

 striated ; the gastrocoeli are represented by three shallow depressiose, 

 the space between them being finely striated. 



Bcnyllus, gen. no v. 



Median segment completely areolated, its apex spined ; the posterior 

 median area largely projecting into the areola ; its spiracles linear, 

 curved. Scutellum convex, rounded, its sides sharply margined. 

 Mandibles unequally toothed, the upper much longer than the 

 lower. Clypeus not separated from the face. Occiput not margined. 

 Wing areolet 5-angled, narrowed above ; the transverse basal nervure 

 interstitial. Legs stout, the tarsi long, spinose. Abdomen with 

 seven segments ; the apex of the petiole curved ; the gastrocoeli almost 

 obsolete; the ovipositor largely projecting ; the 7th segment is nearly 

 as long as the 6th ; the ventral keel stout, extending to the apex 

 of tlie 5th segment — to the l)ase of the ovipositor. Antenna3 stout. 



A genus of Amhli/2Jygi characterized by the stout, 

 unequally-toothed mandibles, the stoutly-keeled scutelluras, 

 the spined median segment, and by the posterior median 

 segment area largely projecting into the areola.
