82 CASEY 



3 — Body extremely sliort and convex, small in size, the eyes, mesoster- 



num and basal joint of the anterior tarsi nearly as in typical Coji- 

 ionii's, the legs, and especially the antennie, shorter and stouter, 

 the last antennal joint relatively more developed ; maxillary palpi 

 with the third joint relatively somewhat more abbreviated though 

 not so notably so as in the preceding section Brachyontis 



These divisions are extremely unequal in extent, the last two 

 being known at present by but a single species each. 



Coniontis in sp. 



For convenience the various components of this division may 



be assigned to eight groups, defined on broad lines of general 



facies as follows : — 



Punctuation of the upper surface more or less sparse, fine and incon- 

 spicuous 2 



Punctuation conspicuous, especially that of the elytra which is gener- 

 ally very coarse 5 



2 — Body oblong, never much more than twice as long as wide 3 



Body elongate, much more than twice as long as wide 4 



3 — Body large in size I {abdomiJialt's^ 



Body small in size II (^opaca') 



4 — Body parallel inform in both sexes Ill {viatica) 



Body more or less distinctly cuneiform in both sexes but particularly 

 in the male IV {cuneata) 



5 — Body decidedly more than twice as long as wide, oblong 6 



Body shorter and generally more oval, never much more than twice as 

 long as wide 8 



6 — Form subdepressed or much less convex than usual, the punctures 



bearing each a more or less elongate, subdecumbent and very evi- 

 dent hair V {sjibpjibescens) 



Form norm ally convex 7 



7 — Punctures of the elytra moderate, bearing each a stiff erect and 



sometimes very conspicuous seta VI {setosa) 



Punctures generally larger and more conspicuous, nude or bearing each 

 a small inclined and less conspicuous coarse hair, the elytral 

 sculpture more or less rugose VII (^eschscholtzi) 



8 — Elytral punctures never conspicuously setose, usually completely 

 nude, very variable in size, the sculpture vai'ying from compara- 

 tively smooth to extremely rugose VIII (^ova/is) 



These groups also correspond fairly well with geographic 

 distribution.
