5 2 CASEY 



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

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

 toJitis^ 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 sui-face 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 (yabdomhialis^ 



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 (^subpubescens) 



Form normally 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 {esckscholtzi) 



8 — Elytral punctures never conspicuously setose, usually completely 



nude, very variable in size, the sculpture varying from compara- 

 tively smooth to extremely rugose VIII (ova/is) 



These groups also correspond fairly well with geographic 

 distribution.
