EUPLECTINI 111 



Legs with the femora distinctly inflated; middle femora ventrally strongly 

 sinuate, with a conspicuous blunt triangular tooth at base as a consequence 

 of this sinuosity; tarsi three-segmented, euplectine, first minute, second and 

 third much larger than first, second longer and thicker than third; third 

 tarsomere bearing a single, large, arcuate claw. 



Allotype Female is similar throughout save that (1) the fourth tergite is 

 not much longer than the third, the five tergites being subequal in length; 

 (2) only six stemites, with the first very short, second longer than first and 

 third; third and fourth subequal; fifth one-half as long as fourth; sixth large, 

 as long as second and third united, subtriangular, with lateral margins sinuate 

 and apex rounded to fit into a deep ventral incisure of the ventral margin of 

 the fifth tergite; (3) femora not inflated, and middle femora simple. 



Note that the female has the vaulted vertex and bifurcated sulcal pattern 

 present in the male. 



Described upon a male and a female specimen, both collected at the same 

 time and niche, beneath the bark of a log at Armour 8, July 26, 1936, on Barro 

 Colorado Island, Gatun Lake, Panama Canal Zone, by the author. The species 

 of the genus are as follows: 



claviceps Reitter. 1882. Colombia. Genotype, {nee caviceps auct.) 

 clavicornis Sharp. 1887. Guatemala. 

 femoralis Sharp. 1887. Guatemala. 

 furcalis new species. Panama Canal Zone. 



NEODALMUS (R affray, 1890) 



This is a melbaform, monotypic genus which is isolated by the pronotal 

 structure: the disc of the pronotum is crossed longitudinally by a median 

 carina, analogously to the brachyglutine Bunoderus. There is a single species: 



carinatus Raffray. 1890. Venezuela. Genotype. 



DALMOPLECTUS (Raffray, 1890) 



This genus was created by Raffray to contain a melbaform species, known 

 only from the female sex, originally placed in the Tychini. The fact that the 

 posterior coxae are distinctly, although slightly, separated serves to differentiate 

 the genus from Melba. 



batrisoides (Reitter). 1882. Brazil. (Dahnodes). 



MELBAMIMA (Raffray, 1909) 



This genus contains a single melbaform species, separated from Melba 

 chiefly on the structure of the antennae (PI. VI). These organs are eleven- 

 segmented, with the first two segments relatively ver>' large and subquadrate 

 and nearly three times as wide as segments III to VIII; the third segment is 

 obconical; fourth to eighth transverse and compactly articulated; IX of the
