far the lavo-est member of the tribe known thus far from North 

 America. 



EUPLECTINI. 



A renewed study of the species aggregated under the name Ra- 

 mecia, shows that they are not in any way closely related to Eu- 

 plectus, but are allies of Trichonyx, and, at the same time, the 

 close general resemblance to Euplectus in bodily form, in conjunc- 

 tion with the well developed second tarsal claw, goes far to dem- 

 onstrate the impropriety of proposing two distinct tribal groups 

 for the genera clustering about Trichon3^x and Euplectus ; at any 

 rate, if we admit two tribes, we must also recognize several others. 

 The species of Ramecia exhibit considerable diversity in general 

 habitus, crinita being quite depressed, with two strong, short 

 basal carinse on the first three tergites ; the remainder are more 

 convex in form, much smoother in sculpture and with less de- 

 veloped abdominal carinse, though in decora the latter are also 

 visible on the first three tergites, becoming very minute however 

 on the third. At present, therefore, I can see no reasonable 

 ground for generic disintegration of Ramecia. 



PYCJVOPLECTIJS n. gen. 



The species forming the first division of Euplectus, as pre- 

 viously defined by the writer (Col. Not., V, p. 454), are not in re- 

 ality congeneric with Euplectus as represented by the last two sub- 

 divisions, and should receive a separate name as suggested above. 

 The species are stouter, less parallel and much more convex in 

 the body, with more remotely separated and pubescent cephalic 

 foveae, connected by a more deeply excavated ambient sulcus, 

 rather more elongate antennae and much more widely exposed 

 met-episterna. They agree with EupJectus in the structure and 

 carination of the abdomen, and in the complete absence of erect 

 capitate setae on the lower surface of the head. 



P. tenellu^i) n. sp. — Linear and nearly parallel, though quite convex, 

 shining, pale rufo-ferruginous tlirougbout, the pubescence rather short, coarse, 

 subdecumbent and moderately dense, with the usual bristling setfeat tbe sides 

 of the abdomen toward tip. Head but slightly wider than long, as wide as 

 tbe prothorax, tbe eyes rather prominent and well developed, at somewhat 

 less than their own length from the base, the tempora strongly convergent and 

 rounded behind them ; surface impunctate in the middle but rugosely sub- 

 punctate along the elevated sapra-orbital surface from base to apex ; fovese 

 near basal third, separated by }-^ the total width, the connecting ambient sulcus
