BEMBIDIIX.E 89 



Elytra each with three dorsal foveae 9 



5 The dorsal foveae on the third interval but very close to the third 

 stria; body very small, polished throughout and uniformly deep 



black; frontal sulci parallel (vile) 46 



The dorsal fovea? subaxial on the third interval 6 



6 Size moderate to rather large; frontal sulci parallel or nearly so. . . .7 



Size always very small 8 



7 Frontal sulci deep and parallel; entire surface highly polished. 



(vinnulum) 51 



Frontal sulci generally parallel but broad and notably shallow as a rule; 

 upper surface more or less alutaceous, at least anteriorly, wholly 

 shining in deject-um; elytra variegated throughout, or only near the 



apex (cordatuni) 52 



8 Elytra oblong, variegated, frontal sulci parallel to feebly or strongly 

 oblique; second antennal joint sometimes as long as the third. 



(affine) 68 



Elytra oval, not variegated, the sulci parallel (miiscicola] 85 



9 Upper surface polished throughout, the elytra variegated; frontal 

 sulci parallel; body moderately large in size (scudderi) 86 



The species described by Mr. Hayward under the name con- 

 stricticolle, was subsequently removed by the author and associated 

 with semistriatum, and I have removed tigrinum Lee., to form the 

 type of a separate subgeneric group, named Leuchydrium (ante p. 

 46); epliippigerum Lee., also included by Hayward, forms the type 

 of the subgeneric group Peryplwdes (ante p. 85). Unfortunately 

 there are a considerable number of the described species in this 

 group that I fail to identify among my material, such as convexulum 

 Hayw., and grandicolle, arattim, morulum, dyschirinum and vile of 

 LeConte, although I have a number evidently allied to the three 

 last named; ceneicolle, versutum and rubiginosum of LeConte, and 

 wickhami Hayw., are also unknown to me at present; perhaps I 

 may have unwittingly renamed some of them in the following tabu- 

 lar statement of our species: 



I Legs, antennae anS palpi deep black throughout 2 



Legs never deep black 7 



2 Elytra uniform in coloration, not maculate with paler tint, except 



occasionally to a minute degree 3 



Elytra with pale irregular fasciae 6 



3 Entire upper surface brilliantly cupreous; elytra never with trace of 



paler spots 4 



Entire upper surface deep black, blue-black or feebly aeneous; species 



allied to coloradense Hayw 5 



4 Body oblong, moderately convex, shining, only very slightly alu- 

 taceous anteriorly, black, with strong cupreous lustre; head three-
