or seven setas and extends nearly to the base, the fourth row four 

 setas, extending to about one-fourth the length from the base, the 

 third row about three setae, extending slightly beyond the middle, 

 the second row two, extending nearly to the middle, the first row 

 being between the sutural and diseal striae and containing two to 

 four setse. 



The setJB are more widely spaced in the rows toward the suture, 

 except in the first row where they become slightly less distant. 

 The setigerous punctures may or may not coincide with the punc- 

 tures of the series, and do not differ greatly from them in form, 

 being merely a little more pronounced. In some species they are 

 not visible at all, but as far as I have been able to observe the 

 margnial line of larger, more closely placed seta3 never becomes 

 obsolete. These are entirely distinct from the excessively minute 

 fine recumbent hairs, borne by the ordinary punctures, and no 

 doubt serve quite a different purpose. 



In the following table only those characters are employed which 

 appear to be of decided importance ; they relate to the sternal, tarsal 

 and antennal structure, and elytral sculpture, and weight should 

 perhaps be assigned to them in the order named : — 



Metastenial process not extending beyond the middle coxae, truncate at apex. 



ovalis 

 Metasternal process projecting beyond the middle coxse, more or less strongly 

 rounded at apex. 

 Third antennal joint equal in length to the two following united. 



Elytra entirely polished, or with but slight trace of reticulation toward 

 apex. 

 Punctures of series very fine, nut becoming decidedly coarser at the 

 sides. 



Form robust, suboblong ; size large penicillatus 



Form less robust, evenly elliptical; smaller in size Sayi 



Punctures of series very fine, becoming abruptly much larger and 

 broadly lunate at the sides ; form narrowly oval and slightly nar- 

 rowed behind Simplex 



Elytra finely and more or less feebly reticulate over the entire surface. 

 Punctures of elytral series extremely feeble and rather indistinct. 

 Antennae pale ; sternal processes very wide, the metasternal scarcely 

 more than twice as wide as the prosternal ; form very broadly 



oval politus 



Antenuie black ; metasternal process narrower, more strongly rounded 

 at apex and about three times as wide as the jirosternal ; form more 

 narrowly oval ; reticulation of upper surface much more feeble.
