Akad. (1. Wisscn., Wien, 1906, p. 64). In that species the 2nd cubital cellule is not 

 appendiculated, as it is in the 2 species I have described. In these, too, the apex of 

 the clypeus is more broadly rounded than usual. Noteworthy is the marked difference 

 in the terminal antennal joints in the 2 species described above. Length 9 mm.

The antenna 1 vary from black to orange. Some examples appear to have the 

 post-scutellum more strongly bituberculated than others. 



Rhynehium Thomson! sp. nov. 



Black, the antenna^, clypeus, a small spot above the antenna?, the outer orbits 

 broadly, pronotum, tegula?, the scutellum .except for a line down the middle (narrower than 

 the red sides), post-scutellum except the apical slope, metanotum, except narrowly in 

 the centre, mesopleura^, a large semicircular mark on the sides of the 1st abdominal 

 segment and the legs, rufous; 2 small spots on the apex of the 1st abdominal segment 

 and a broad band with irregular basal border, on the apical third of the 2nd segment, 

 pale yellow; wings fuscous-violaceous, the nervures and stigma black. Clypeus pyriform, 

 not much longer than broad; the apical part in the middle depressed, the apex itself 

 transverse. Apex of postscutellum with a steep, rounded slope ; the extreme apex bluntly 

 rounded. Sides of metanotum bluntly rounded; irregularly bluntly serrate, the middle 

 transversely striated, the sides at the top more strongly transversely striated. $. 



Length 23 mm.

The puncturation on the head and thorax is strong and close; on the abdomen 

 weak and sparse; on the clypeus stronger and sparser than it is on the front; the fovea 

 on the vertex is broad and curved. In one example the 2 yellow spots on the 1st 

 abdominal segment are absent, and the red lateral marks on it are reduced in size; the 

 antenna 1 , too, are much darker towards the apex; there is a triangular mark on the apex 

 of the propleime. 



This species, as well as the following closely allied one, belongs to SAUSSURES 1st 

 Division, Etudes sur la Fam. d. Vespides, p. 103; cf. also vol. Ill, 175.
