AKT. 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 95 



The wings of this species are slighthly infumated. The inner 

 eye-margins are somewhat divergent at the clypeus. The frons be- 

 tween the antennae is strongly carinate and the carina is continued 

 on the basal part of the clypeus. The pubescence is short and incon- 

 spicuous. The lateral margins of the propodeum are similar to those 

 of recurva. 



I have assigned to this species a male bearing the label '' Victoria- 

 Nyansa, I. Ukerewe. Conrads S. G." The genitalia of this specimen 

 had been removed before the insect reached me. Segments 8 and 9 

 of the flagellum are spinose, and 10, 11, and 1'2 are excavated below. 

 The eleventh is broad and the twelfth is narrowed toward the apex 

 and somewhat curved. In other structural characters this specimen 

 agrees with the type and it also agrees in having the pale line below 

 on the anterior femur and the pale spots on anterior coxae. It 

 differs in that the maculations on the tergites are pale instead of 

 yellow ; that the fascia on tergite 3 is continuous and those on 2, 4, 

 and 5 are only narrowly interrupted; and that 2 incloses a pair of 

 black spots. 



Length 22 mm. Described from three specimens from eastern 

 Africa. The type bears the label, " D. O. Afrika, Kamoga, Fr. 

 Midler S." Allotype bears the label. " D. O. Afrika Mkatta I-VI '09, 

 ^Schonheit S. G."

BEMBIX INSULARIS (Dahlbom) 



Moncduhi iiisularis Dahlbom, Hym. Eur., vol. 1, 1845, p. 186. — Cresson, Proc. 



Eiit. Soc. Phila., vol. 4, 1865, p. 143. 

 Bcmhex insuJaris Handlirsch, Sitz. Akad. Wissenscli. Wien, Math.-Nat. CI., 



vol. 102, 1893, p. 826.— Dalla Torre, Cat. Hym., vol. 8, 1897, p." 506. 



Dahlboni'S description of Monedula insularis is not complete 



enough or detailed enough to enable one to determine just what 



species he had before him, but Handlirsch, in his description of this 



species, .states that he had, among the specimens he examined, two 



; of Dahlbom's types. That being the case, there can be no doubt 



I of the identity of the species. Cresson's description was beyond 



i doubt based upon a species of Bemhex^ and a comparison of his 



I description with that given by Handlirsch convinces me that the two 



authors were dealing with one and the same species. 



In the collection of the United States National Museum are two 

 males from Jamaica that I have referred to this species. On these 

 I males the sixth sternite, in addition to the median process, bears 

 a pair of evident lateral processes, a cliaracter that neither Handlirsch 

 nor Cresson mentions. This character is present also on the males 

 of infumata Handlirsch, nuhilipenms Cresson, and hamata C. L. Fox.
