Part II. 



The present paper contains descriptions of new species of 

 the genus Odynerus, Latr., from various localities, and of a 

 new genus Rhynchalastor from German East Africa. This 

 genus is of particular interest, adding as it does a third genus 

 to Section III. of the family Eumenidse, in which the second 

 cubital cell of the fore wing is petiolate. Of the two known 

 genera of this section, Hymenokmithia, D. T., contains but 

 one species, H. natalensis, Sauss., described from Natal ; the 

 other genus, Alastor, Lepel., is of wide distribution, but 

 principally confined to Australia and S. America, no known 

 species being met with in Tropical Africa. The types are 

 all in the National Collection.

Odynerus conjluentus, Smith, Cat. Hym. Brit. Mus. vol. v. p. 60. 

 Odynerus hyades, Cam. Journ. Straits Asiatic Soc. vol. lvii. 



Smith described this species from Sumatra ; 0. hyades, 

 Cam., is quite identical with Smith's type. There is a speci- 

 men from the Thaungyin Valley, Tenasserim (coll. Bingham)

 Odynerus cilicius, Cam. Journ. Str. Asiatic Soc. vol. xxxvii. p. 11 



(1901). 



Both described from Sarawak, Borneo ; the species 

 described by Cameron is identical with Smith's species, with 

 the type of which it has been compared.
