The European genera Borhoropora Kr., and Mataris 

 Fauv., are not represented in the material before me at 

 present and it is therefore impossible to advance any useful 

 suggestions as to their proper place in the series. The 

 genus Euliusa may be rather closeW allied to Rechota Shp., 

 but is probably not the same, and it is possible that the 

 Gnypeta mexicana, of Sharp, may be a Euliusa. The for- 

 eign genera indicated above may be referred to as follows: — 



Neolara Shp.— This name was recently proposed by Dr. 

 Sharp for a small species resembling Meronera somewhat in 

 external features, but differing in having the middle coxae 

 still more widely separated, their acetabula defined through- 

 out by an extremely tine but continuous bead and in having 

 the prosternum much more developed between the coxae, 

 with its apex drawn out and extremely acute. The follow- 

 ing species may be assigned provisionally to the genus. 



Rather stout, subparallel, only moderately convex, shining, pale piceo- 

 testaceous in color, the abdomen more blackish, the antennae iufuscate 

 toward tip; head much wider than long with the hind angles rounded, 

 minutely, rather sparsely punctate; antennae slender, extending to the 

 middle of the elytra, gradually, rather feebly incrassate toward tip, the 

 basal joint much longer than the second or third, the latter both elong- 

 ate; prothorax barely as wide as the head, about a fourth wider than 

 long, the sides strongly rounded and subprominent at apical third, 

 thence converging and nearly straight to the broadly arcuato -truncate 

 base, the angles obtuse and rounded; surface strongly convex, nar- 

 rowly and very obsoletely impressed along the median line behind the 

 middle, the punctures fine but close-set; elytra transverse, one-half 

 wider and a third longer than the prothorax, the punctures somewhat 

 finer than those of the prothorax and less close -set, the surface paler 

 toward the humeri and broadly along tha entire apex ; abdomen slightly 

 narrower than the elytra, parallel and straight at the sides, very min- 

 utely and rather closely punctulate, the basal Impressions wholly im- 

 punctate; pubescence throughout short and inconspicuous; sixth ventral
