128 Orper—HYMENOPTERA. 
hind tarsi in the opposite sexes (fig. 8d, male; fig. 8¢, female), is noticed in the specific character given above. 
The tarsal ungues have a small tooth at the base, and there is a small heart-shaped pulvillus between them, 
This is, I believe, the first species of this curious group, described as an inhabitant of the continent of 
Africa, thus proving, in conjunction with the Australian insect represented in fig. 2, that the genus is dis- 
tributed over all the four quarters of the globe, species from Europe, Asia, and America having previously been 
described. 8. (Fenatopus) ruficeps Smith, is from Macassar, S. Indicus Westw., as its name imports, from India ; 
and in the British Museum is a species from Solomon’s Island (New Hebrides), of which the following is the 
character :—
