Discussion 
I have thought it best to treat Hoplisoides umbonicida and 
H. vespoides as distinct species. Both are listed by Bohart and 
Menke (1976), and Professor Bohart confirms (1976, in litt.) that 
he considers umbonicida to be a species separate from vespoides. 
Pate was a meticulous worker and described both sexes of um- 
bonicida in detail, and it seems unlikely that he would have recog- 
nized it as a new entity unless he was reasonably certain it was 
distinct from related species. It would be interesting, however 
improbable, should two similar sympatric species occur in Trini- 
dad, nesting possibly under slightly different conditions, and 
both provisioning their nests, so far as known, exclusively with 
Umbonia spinosa and no other prey. Until Pate’s holotype and 
vespoides are compared, it will not be possible to resolve the 
problem. 
Many neotropical gorytines apparently mimic social vespids 
of the tribe Polvbiini. Pate (1941) pointed out that H. umboni- 
cida bears a striking superficial resemblance to the ve/utina phase 
of Brachygastra lecheguana (Latreille) — a phase now identified
