DASYPOGONIN^. 



707 



2 (3) Thorax hairy but without strong bristles. Abdomen compara- 



tively short and plump. 



Legs short and thick. Moderate-sized species. 



11. ISOPOGON. 



3 (2) Thorax with strong bristles, there being at least a pra^sutural and 



a supra-alar. Abdomen elongate, more or less slender. 



Legs long and not very robust. 



4 (7) Face-beard limited to the mouthmargin and usually composed of 



very few bristles, but occasionally with slight short pubescence 

 above it (fig. 371). 



N.B. — This character may be misleading in some species of 

 Saropogon until experience has rendered it intelligible, but with 

 practice it becomes a very convenient distinction.

Fig. S72.—Dasypogon teutonus <J. x 12. 



5 (6) Scutellum with marginal bristles. Collar moderate in length and 



bearing bristles. 



Species more stoutly built and more bristly than in Cenopogon. 

 Face-beard composed of several bristles. Metapleural fan of bristles 

 well developed. Femora without bristles on the underside. 



Saropogon. 



6 (5) Scutellum without any bristles. Collar elongate and without 



bristles. 



Species very elongate and bare. Face-beard composed of two 

 bristles. 



N.B. — I do not unite this genus with Laparus, because I believe a 

 number of allied genera will be formed out of the species now placed in 

 that genus. 



Cenopogon. 



7 (4) Face-beard dense and extending up to at least the middle of the 



face (fig. 372).
