25 (28) Basal abdominal segment with extremely fine, but numerous punctures -q- 



ou the disc, or else the segment has a complete, or all but complete, M^^^^ 

 apical impression, easily seen in some aspects, though feeble. 



26 (27) Basal segment on its apical part widely convex between the lateral 



ridges, so that there is no definite apical impression on the middle 

 part ; the 2nd segment also with the apical impression effaced or 

 very indistinct in the middle ; face very wide 



.... laticeps Sch. {semipunctulatus E. S.). 



27 (26) Basal segment with complete apical impression, or almost so; that of 



the second segment still more distinct ; face less wide 



.... pauxUlus var. immarginatus Sch. 



28 (25) Basal abdominal segment polished black, at most with a few hardly 



perceptible punctures, and without an apical impression on the 

 middle part, the segment being evenly convex there between the 

 lateral ridges. 



29 (30) Face in front view broadly ovate or widely roundish. 



(Tomentose spots of 2nd abdominal segment distinct and dense in 

 good specimens.) fulvicorjiis K. 



30 (29) Face, in front view *, somewhat oblong-ovate, the clypeus more 



produced. 



(Sculpture of front of head denser and much less distinct in most 

 specimens, often not distinguishable as puncturation, but rather as 

 obscure granulation or recticnlation, more rarely almost lilie tliat of 

 fulviconns ; punctures of mesonotum still finer than in the preceding 

 and tlie tomentose spots of the 2nd iibdominal segment often 

 indistinct or hardly noticeable.) 



.... freygessneri kU]i. 



31 (20) Mesonotum smooth and shining all over between the punctures, 



which are either coarse or deep and distinct. 



(Second abdominal segment without a tomentose spot on each side 

 at the base, or at most with a very small one.) 



32 (33) Abdomen polished, practically impunctate, at most with a few isolated 



punctures lueiis K. 



33 (32) Abdomen with the 2nd and 3rd segments copiously and finely punc-

34 (17) Piopodeum at the hind angles without a distinct raised margin, its 



angles rounded off. 



3o (36) Mesonotum very strongly shining, the surface smooth, the punctures 

 not at all close ; basal segment of abdomen finely punctured, the 

 punctures not becoming conspicuously dense towards the sides, nor 

 is it densely punctured along the apical margin. 

 .... villosulus K. 



36 (35) Mesonotum rarely very shining, generally for a lai-ge part the surface 

 is minutely sculptui-ed between the punctures, which are more or 

 less dense, at least about the middle, except in one species, and this 

 has the disc of the basal alidominal segment very remotely punc- 

 tured, but towards the sides the pui.ctures (which are extremely

 wide and much less conspicuously produced apically,
