382 ON THE CARENIDES (FAM. CARABID.K), No. IV., 



trochanters with the apex less drawn out into an acuminate point 

 It seems impossible to unite the two unique specimens of C. 

 regulare and C. acutipes before me under one specific name, 

 though subsequent observations may show them to be varieties 

 of a widely spread and variable species. The anterior discoidal 

 punctures of the elytra are placed close behind the humeral angles 

 (2 mm. distant), the posterior about the apical fifth. I have 

 placed C. acutipes and C. regulare in the same group as C . quadri- 

 pauctatum, Macl., though the} r seem to have but little affinity to 

 that species. 



Carenum subplanatum, Bates. 



I identify as C. subplanatum, Bates, a species in Mr. C. French's 

 collection, of which the following is a description : — 



Head black with purple reflections near posterior extremities 

 of frontal sulci; prothorax black, violaceous towards margins; 

 elytra bright violaceous; under surface black. Head transverse 

 (25 x 3-7 mm.), convex, transversely impressed across occiput; 

 frontal sulci deep, diverging lightly backwards and meeting 

 posterior transverse impression at full depth; frontal spaces con- 

 vex, the lateral ones abruptly acclivous and bipunctate above 

 eyes; clypeus with median part truncate, intermediate angles 

 prominent, short, acute; eyes deeply set in orbits, not prominent 

 or convex; suborbital channels to receive antennae wide, short, 

 longitudinally divided by a short, weakly developed oblique ridge. 

 Prothorax transverse (3 -2 x 4-2 mm. ), convex, shortly lobate at 

 base, rounded at posterior angles; apex truncate, anterior angles 

 hardly at all advanced; border narrow: two marginal punctures 

 on each side. Elytra oval (7 "7 x 44 mm.), subdepressed, roundly 

 declivous at sides and apex, bipunctate towards apex ; base 

 vertical above peduncle, lightly and widely impressed near each 

 humeral angle, each of these depressions quadripunctate; border 

 narrow, thick towards apex (as in Unto ma), slightly thickened 

 and upturned at humeral angles; inflexed margins narrow, convex 

 backwards from middle of first ventral segment. Legs as in 

 Eutoma, anterior tibiae bidentate. Length 14, breadth 4 4 mm.
