EUPLECTINI 71 



small subbasal tooth and crenulate from the tooth to anterior 

 third; base of elytra with four small, rudimentary foveae 

 on each elytron, these foveae being apically margined by a 



triarcuate or quadriarcuate transverse basal carina 



PANARAMECIA, new genus 



43 (30). Integument punctulate and pubescent DALMOPLECTUS 



Integument glabrous, without punctures or pubescence 



EUPSENIUS (this genus 



will key out here if the shape of the posterior coxae has 

 been incorrectly diagnosed. It belongs in Brachyglutini). 



44 (37) . Head with two vertexal foveae ; lateral margins of the pronotum 



sharply defined, with the lateral fovea on each side wholly 

 within the margin, and wholly visible from a dorsal view 



(female known only) TRIMIOSELLA 



Head with four strongly formed foveae, two vertexal foveae 

 widely separated and on a line passing through the posterior 

 half of the eyes, and an anterior pair of foveae, closer to- 

 gether and near the frontal margin, one slightly behind and 

 mesiad of each antennal prominence; lateral pronotal mar- 

 gins smoothly rounded as in Melba, but the lateral subbasal 



fovea visible on each side from a dorsal point of view 



R AMELBID A, new genus 



FARONOMA (Raffray, 1894) 



cavangula (Reitter). 1894. Chile. Genotype. (Rybaxis) 



The single species of this genus, originally described in Rybaxis of the 

 Brachyglutini, transferred to Faronini in the genus Faronoma by Rafifray, 

 and subsequently (1903) placed by Raffray in the Trichonychini, is here 

 placed in the enlarged Euplectini. It is one of two monotypic genera of 

 trichonoforms in which the male sex is known only, and in this sex the tergites 

 are remarkably modified. In this species the male has subequal tergites and 

 the second tergite has each lateral margin strongly tuberculate and armed. 

 Described from Valdivia, Chile, it has not been recorded since. 



ALLOBROX (Fletcher, 1928) 



dampfi Fletcher. 1928. Mexico. Genotype. 



The author of this remarkable species has this to say regarding its 

 affinities: "Allobrox is without doubt more closely allied to the Chilian 

 Faronoma than to any other of the Trichonychini. These two genera are alone 

 in the tribe in possessing modifications of the dorsal abdominal segments re- 

 minding one of Brachygluta."
