518 Mr. G. Meade-Waldo's revision of the species of 



A black species, the silvery pubescence on the ^ clypeus 

 is very conspicuous. 



Subgenus Hoplomerus, Westwood. 



0. (Hoplomenis) spiniger. 



0. (Hoplopus) spiniger, Schulthess. Soc. Entomolog. xxix, 

 No. 14, pp. 73-74 (1914). 



This species has well-developed tubercles on the sides of 

 the median segment; the male has the antennae rolled in 

 spiral, as is usual in the subgenus Hoplomerus {Hoplopus). 

 Typical species of this subgenus, of which 0. spinipes, L., 

 may be considered the type, have the median segment 

 rounded posteriorly on the sides, so that it is doubtful 

 whether the species under discussion is really referable to 

 the subgenus. Possibly the Ethiopian representatives of 

 the unwieldy genus Odynerus will eventually subdivide 

 into further subgenera. For the present it is better to 

 include them in Hoplomerus, on the strength of the male 

 antennal characters. 



0. (Hoplomerus) zebroides, sp. n. 



9. Niger; mandibiilis, clypeo, antennis basi, macula inter- 

 antennali, linea post oculos, pronoto, soutello, postscutello, tegulis, 

 maculisque mesopleuris ferrugineis ; pedibiis (coxis trochanteri- 

 busque exceptis) ferrugineis; oculorum sinu. abdominis fasciis 

 apicalibus interruptis, lateribus dilatatis sternitibus extremis 

 lateribus, pallide luteis. Alis flavohyalinis. Long. 13J mm. 



A robust species, with the head and thorax broad. Clypeus 

 convex, as broad as long, shallowly emarginate at apex ; mandibles 

 stout, apically dentate; anterior margin of pronotum truncate, the 

 sides rounded, and slightly widening towards the tegulae ; disc of 

 mesonotum with a series of shallow but distinct sulci (parapsidal 

 grooves ; scutellum on a rather higher plane than mesonotum, post- 

 scutellum truncate posteriorly ; median segment concave, the sides 

 produced to form prominent tubercles. First segment of abdomen 

 broadly rounded, short, following segments of normal sculpture. 



Head and thorax with coarse, even punctures, abdomen more 

 finely punctured. The head and median segment with a thick 

 covering of pale pubescence, the rest with a fine short sericeous 

 pile. 



Wings unicolorous golden hyaline, rather fuscous in radial cell. 



Length 13^ mm.
