7. Tibial process comparatively broad, with its 



upper surface somewhat concave, and its 

 length more than half that of first tarsal 

 segment ; tibia with inner margin without 

 teeth,* and outer margin with teeth for 



about half its length .... Dibolia Jacoby (Text-fig. 15/). 

 Tibial process very deeply cleft, slightly 

 shorter than first tarsal segment ; lateral 

 edges with very min ute serrations and 



bristles only near apex .... Megistops Boheman (Text-fig. 15^). 



8. Femur with ventrally situated blunt process ; 



tibial process very small, with bluntly 

 pointed apex ; apex of tibia acuminate ; 



lateral edges without serrations . . Argopist.es Motschulsky (Text-fig. 15h). 

 Femur without such process . . .9. 



9. Apex of tibia narrowly produced into a spatu- 



late process ; outer lateral edge of tibia 

 with serrations and emarginations, and 

 with strong bristles near apex ; tibial spur 



small and pointed . .... Pseudodibolia Jacoby (Text-fig. 

 Tibia comparatively short, broad, and pro- 

 duced into a point at apex ; tibial process 

 large, slightly shorter than first tarsal seg- 

 ment, bluntly pointed, with surface 

 ridged ; lateral edges of tibia with wide 



emargination near apex . . . . Sphaerophyma Baly (Text-figs. k, and 16). 



In his generic diagnosis Baly writes : " Acetabulis anticis integris." I 

 have, however, examined the genotype in the British Museum, and find that the

anterior coxal cavities are quite open behind ; in fact, so widely are they open 

 that there cannot possibly be any doubt on the subject (cf. Text-fig. 16). 



* This is in a preparation of D. occultans, but in a preparation of D. scMllingi a few teeth 

 are visible on the inner margin at the apex.
