if there are only two transverse cubital nervures, I do not see how it can be separated 

 from Rhinopsis, and must, in fact, bc rcgarded as pertaining to that genus, unless, 

 indeed, the diflference in thc neuration between the latter and Ampulcx be not regarded 

 as of generic importance, in which case the two may be united.«

Rhinopsis rußcornis Ci\m., Mem. Proc. Manch. Lit. Phil. Soc, II (4. scr.), pag. 25, o 1889 



»Niger, antennis, ore, thorace, petiolo, tarsisque, rufis; alis hyalinis, f'usco bifascia- 

 tis; nervis sordide testaceis. 9. Long. 10 mm. 



»Antennae shorter than the thorax; the basal Joint curved, as long as the third, 

 which is two-thirds longer than the fourth. Head coarselv alutaceous, almost punc- 

 tured; the front keeled, but not distinctly, the keel being interrupted at the base and 

 apex; eyes parallel. The keel on the clypeus projects at the apex into a stout sharp 

 tooth, and there is a shorter and biunter tooth on either side of this. Prothorax a little 

 shorter than the head; the top part raised, narrowed and separated from the lower, and 

 deeply furrowed in the centre; the prosternum and extreme base of pronotum black. 

 Mesonotum shorter than the prothorax, parapsidal furrows slightly diverging at the 

 base, and there is an indistinct furrow between them. Meta- longer than the meso- 

 thorax. The metanotum with a broad, shallow, somewhat oblique, depression on either 

 side; in the centre (between the depression) are thre keels, the central straight, the lateral 

 converging towards the apex; but none of them reach the apex of the metanotum. The 

 metapleurae are smooth, shining, impunctate; the rest of the metathorax strongly trans- 

 versely striolated, runnig in parts into reticulations. The apex is rounded, margined; a 

 blunt tooth on either side, and the apex roundly and shallowlv incised. The apex is 

 almost perpendicular, broadly furrowed in the centre, and covered with a moderately 

 long white pubescence. Pro- and mesonotum coarsely aciculated, sparsely covered with 

 a white pubescence. Petiole smooth, shining, clavate at the apex; second abdominal 

 Segment as long as all the succeeding segments united; the latter above (especially at 

 their junction), as well as the sides of all, covered with a short pale pubescence. Legs 

 covered with a white pubescence, the femora thickened in the middle, the second cubital 

 cellule is narrowed towards the top; the transverse cubital nervures are straight. Wings 

 not much longer than the thorax. 



»This species is closelv related to the European R. rußcollis Cam., but is much 

 larger, the antennae and tarsi are red, the metanotum is entirely red, the wings are 

 shorter and not so broadlv infuscated in the middle, and with thc nervures for the greater 

 part testaceous ; and the apex of the petiole is much narrower, thinner, and more club-like.
