punctate face, subverfcical first recurrent nervure, and in liaving 

 the head behind the eyes constricted in a straight line, which 

 renders the eyes peculiai-Iy prominent. — Apparently rare and 

 confined to ITganda. whence I have seen both sexes taken in the 

 ]\[abira Forest at 3500 to 3800 feet during July, and the Budongo 

 Forest at 3400 feet during mid-December 1911, by S. A. Neave ; 

 and about Entebbe during the middle of March 1914, by C. C. 

 Gowdey. 



11. COTHURNATOR, Sp. n. 



A testaceous species, with both antennae and hind legs white- 

 banded black. Instantly recognised from the remainder of the 

 genus by the pui-e white third and fourth (and in d' fifth) joints 

 of the hind tarsi, which are peculiarly slender ; the whole thoracic 

 sculpture, including that of the scutellum, is as in X. inermis, 

 but the abdomen is more fusiform and less elongate with its disc, 

 especially apically, more finely punctate and almost nitidulous ; 

 the capital structure approaches that of X. colli/er, though the 

 temples here are very much shorter and the occiput falls away 

 immediately behind the black ocellar region. Length, 12 mm. 

 (S 2 • — '^^^^ distribution seems distinct from that of the fore- 

 going sjiecies, for those I have examined are from 4500 to 5000 

 feet at Western Ankole in mid-October 1911 ; and the Siroko 

 River, near the west foot of Mount Elgon at 3600 feet, during 

 the preceding August ; in Uganda. 



12. GEMIKATOR, Sp. n. 



This and the following species are so difterent from all the 

 above in their deeper ferruginous coloration, black antennje, 

 shorter and stouter legs, in the rather broader temples, much 

 longer upper mandibular tooth and more robust outline, that 

 they will probably not be found congeneric. X. geminator is 

 easily recognised by the longitudinal black mark occupjang the 

 confiuent external and dentiparal metanotal arete ; it is similar to 

 the next species but the legs are testaceous throughout, the 

 metanotal transcarina is strong with well-defined, subcircular and 

 dull areola, and no trace of costuUe. Length, 12-13 mm. J 

 only.— Two males were captured on the N.W. and at Buddu on 

 the W. shores of the Victoria Nyanza at about 3700 feet by 

 Neave, in the middle of September 1911. 



13. AREOLATOR, sp. n. 



A ferruginous species with the legs neither elongate nor 

 slender, upper mandibular tooth long and transcarina of the 

 immaculate metanotum weak ; flagellum entirely black, setigerous 

 and somewhat stout. Dift'ering from the last species in the 

 possession of a well-defined elongate and shining areola with 

 some trace of costuUe ; and from the remainder of the genus in 

 having the extreme base (only) of the hind tibias, along with the
