ventral segment with the transverse basal depression well marked. 

 Length, 12 mm. 



One specimen. Sheikh Husein, September 30, 1894. Is appar- 

 ently related to N. radamce Saussure, from Madagascar, and may be 

 identical with the var. b., mentioned by that author. The radial 

 (marginal) cell of radamce is said to be perpendicularly truncate, 

 whereas in apicalis it is obliquely so. It also agress fairly well with 

 the description of Larra rubella Smith, of which only the female is 

 described. 

 Miscophus ctenopus Kohl. 



Berbera, July 4, 1894. One 9 specimem. 

 Tachysphex fluctuatus Gerst. 



One male specimen. Same locality as the preceding species. 

 Helioryctus melanopyrus Sm. 



One specimen, a female. Near Lake Stephanie, June 20, 1895. 

 It is somewhat larger than the specimen described by Smith, and 

 measures 14 mm. in length. Helioryctus is, perhaps, synonymous 

 with Sericophorus Sm. (uou Shuck.) = Tachyrhostus Sauss. Seri- 

 cophorus Sm. has priority over TachjrJiostus, having been described 

 on p. 33, Ann. & Mag. Nat. Hist, 1851, VII.
