and irregularly rugose with only one or two weak longitudinal rugae 

 laterally. 



The species closely resembles antennata, the new species described 

 herewith, but differs in the following respects: Flagellar joints in 

 the female less strongly produced dorsally, the longest tooth being 

 much shorter than the length of the segment; ninth flagellar joint 

 closely fused with the tenth, often hardly distinguishable, the anten- 

 nae therefore often appearing to be only 11-jointed ; transverse rugae 

 on mesoscutum a little less coarse, the surface of mesoscutum there- 

 fore more shining; parapsidal grooves complete but not deeply im- 

 pressed and with some of the transverse rugae continuous from the 

 middle lobe of mesoscutum onto the scapulae; axillae and scutellum 

 not distinctly longitudinally striated but weakly irregularly rugose 

 and shining, and the median groove on scutellum broad and shallow; 

 scutellar process almost exactly like that of antennata but the apex 

 of scutellum beneath the process nearlj^ smooth; propodeum irreg- 

 ularly rugulose, more or less shining except laterally; abdominal 

 petiole very nearly smooth; second tergite sparsely punctate, the 

 punctures most numerous on the sides of tergite ; ovipositor slender, 

 perfectly straight, and armed with onlj^ about three or four very 

 weak teeth apically; hypopygium apparently with only five or six 

 long hairs at its apex. 



The male differs from the male of antennata by having the first 

 flagellar joint without a dorsal tooth, the branches on joints 2-9 

 slightly longer and not quite so broadly compressed, the ck>T^)eus and 

 supraclypeal area polished like the rest of face, mesoscutum with 

 the median lobe irregularly transversely rugoso-striate, the rugae 

 continuous across the parapsidal grooves onto the scapulae, scutellum 

 and axillae not longitudinally striated but coarsely rugoso-punctate, 

 apex of scutellum beneath the apical process and also the propodeum 

 strongly rugoso-punctate, abdominal petiole about one and one-half 

 times the length of posterior coxae and practically smooth. 



The straight, slender, and weakly toothed ovipositor, when com- 

 pared with the strongly curved, thicker, and strongly toothed oviposi- 

 tor of antennata^ indicates a different method of oviposition and 

 suggests the possibility that the two species do not belong in the 

 same genus. The ovipositor of convergens is similar to that of at 

 least some of the species of Stilbula but the fact that the flagellar 

 joints in the female are serrate, and in the male have long branches, 

 at once excludes it from that genus. Its great similarity to antennata 

 in all respects, except the ovipositor, constrains me to believe the 

 two should be placed in the same genus and that both are congeneric 

 with Schiza^'pidia fv/rcifera Westwood.
