II. RUBRICEPS GROUP 



Lower half of frons with a median pair of carinae or group of wrin- 

 kles that are vertical and parallel ventrally, more dorsally curved 

 outward above each antennal socket; upper tooth of mandible about 

 the same length as lower tooth; notaulus sharp; mesopleurum with 

 fine to coarse punctures, usually also with longitudinal wrinkling, this 

 wrinlding poorly developed in smaller males; basal transverse carina 

 of propodeum complete, incomplete, or absent; apical transverse ca- 

 rina of propodeum absent or indistinct; propodeum very finely to 

 coarsely punctate, usually with wrinkling that is more or less trans- 

 verse; first tergite of female without a dorsolateral longitudinal carina. 



This group includes the six species treated below and five additional 

 species ranging from Mexico to northern South America. The extra- 

 limital five comprise three undescribed species, Joppidiurn ardens 

 Cresson 1873 (=Joppidium ruficolle Cameron 1885), and Joppidium 

 coerulipenne Cameron 1885 {=Opisoxestus jerrugineus Ashmead 1900). 

 The synonymy is new.
