 thickness, the third joint is a httle shorter than the fourth, and is 

 neither thickened nor curved. The ahdomen is somewliat compressed 

 and has tlie petiole longer than it is in the female. 



Paramblynotus carinifrons, sp. n. 



Black ; the abdomen, except the first segment, red, densely 



covered with white stiff pubescence, densely so on the sides of the 



head, on the pleurae, tibiae, and tarsi ; wings, to the transverse basal 



nervure, hyaline, the rest fuscous violaceous, the nervures black. 



? . Length 8 mm. 



Face rugosely punctured above, the rest covered with stout 

 curved striae. Front and vertex smooth, the sides raised, margined 

 on the inner side, the raised part becoming gradually widened below 

 and covered densely with white pubescence. Pronotum coarsely, 

 irregularly reticulated. Mesonotum less coarsely, irregularly striated 

 at the base, the rest irregularly reticulated. Scutellum more strongly 

 and regularly striated than the mesonotum. Metanotum very short, 

 perpendicular, reticulated. Propleura? coarsely reticulated, the meso- 

 and metapleurae smooth, sparsely haired. 



Paramblynotus annulicornis, sp. n. 



Ferruginous, the antennce, except the scape, which is ferruginous, 

 and the eighth, ninth, and tenth joints of the flagellum, which are 

 white, the four anterior coxae, the greater part of the femora, apex of 

 hind coxae, and the hind femora, tibite and tarsi, the sternum and the 

 abdomen, black ; wings hyaline, the nervures black, a black cloud 

 covering the radial cellule and extending backwards to shortly 

 beyond the middle of the wing, becoming gradually narrowed and 

 forming a longish triangle. 



Face closely reticulated, the front and vertex smooth, the sides 

 raised, irregularly reticulated and margined on the inner side. 

 Temples stoutly irregularly, longitudinally striated. Pro- and meso- 

 notum with scutellum and propleurae coarsely reticulated. Meso- 

 pleurae smooth, the metapleurge coarsely reticulated. Metanotum 

 with a depressed area, narrowed above in the centre, the sides 

 widely reticulated. Abdominal petiole more than twice longer than 

 wide and bearing stout longitudinal keels. ^ . Length 5 mm. 



Abdomen smooth and shining, somewhat compressed, as long as 

 the thorax. Cubitus narrow, not very distinct, roundly curved. 

 Frontal keel stout, and it is continued, but more narrowly, down the 

 face. Cheeks stoutly keeled. 



Xystus horneanus, sp. n. 



Black, smooth, and shining, the third joint of antennae testaceous, 

 the legs pallid yellow, tinged with fuscous ; wings hyaline, iridescent, 

 the nervures fuscous, the outer edges distinctly ciliated; radial 

 cellule closed along the fore margin, where it is clearly longer than it 

 is from the margin to the second cubital cellule ; the apical abscissa 

 of radius roundly curved, longer than the basal and thicker than it ; 

 second cubital cellule not defined, the cubitus obsolete. Antennae
