20 (19) Scutellum generally to a larf;e extent distiiictl}' punctured, the 



surface not much rougher than that of the niesonotum ; antennae 

 shorter ; when the head is laid hack, not reaching to the apex of the 

 hasal abdominal segment. 



21 (22) Face in front view extremely wide across the eyes, transverse, the 



clypeus hardly produced. 



(Ventral segments with short erect hairs; general appearance 

 most like fuhicornis, which it approaches in the length of the 

 antennae, but separable at once by its finely punctate, smoother 

 scutellum, and the narrow and very elongate 2nd and 3rd joints of 

 the hind tarsi, as viewed from the side.) 



.... laticeps Sch. (=se))ii2)tmctulattislE.S. nee Sch,). 



22 (21) Cly])eus more or less strongly produced, the face not extraordinarily 



wide. 



23 (24) Labium not entirely bright flavous, often black, pitchy, or reddit^h, or 



to a small extent flavous .... calceatus Scop. 

 2-1 (23) Liibruni bright flavous (like the apex of the clypeus) over the whole 

 .'iurface or almost so. 



25 (26) Face in front view broader, more strongly rounded at the sides and, 



if the portion bej'ond the apical margin of the eyes is left out of 

 consideration, almost circular in outline. 



(Toraentose spots at sides of 2nd segment dense and conspicuous in 

 good specimens.) calceatus var. {cylindrivus F.). 



26 (27) Face in front view narrow and subelongate ; leaving out the produced 



clypeal portion, the outline is suboval. 



(Tomentose spots often feeble or indistinct, even in fre.'-li 

 examples.) (ilhvpes K. 



27 (18) Antennae with at least a considerable unmber of the flagellar joints 



distinctly rufescent, or in some species fulvescent, beneath. 



28 (29) Propodeum, seen from in front, more or less finely rugose anteriorly, 



the wrinkles not reaching the brow of the declivous posterior 

 surface, but leaving a large part with mere surface rugulosity or 

 granular-like sculpture. Lateral angles of the pronotum distinct 

 and subprominent, rectangles or nearh' so. 



(Second ventral segment of abdomen with more or less numerous 

 short but erect hairs, the bind tibiae usually with a yellow line 

 from base to apex above.) .... vialachurus K. {longulus Sm.). 



29 (28) Propodeum generally rugose right up to the brow of the declivity ; 



lateral pronotal angles very indistinct. 



30 (31) Second joint of the hind tarsi viewed laterally very elongate, nearly 



parallel-sided, about t\\ ice as long as wide ; face in front view very 

 wide, evidently transverse across the eyes, the clypeus hardly ]n'o- 

 duced. 



(In normal examples the basal abdominal segment is copiously or 

 even densely punctured, but on its ai)ical portion impunctate or 

 almost so, the surface there being evidently (microscopically) ru- 

 gulose, not polished. Eed-banded specimens occaaionally occur.)
