EIUSTALODES. 89 



third and fourth segments are sometimes reduced or wanting. 

 The black band or spot on the frons of the female is usually broad 

 and intensely black, bat sometimes much reduced and less distinct. 

 A good character of this species is the broad, shining black, upper 

 occipital border in the female. 



There are in the collection two males and eighteen females of 

 the typical form : Obuasi, Ashanti, v.-ix. 1907 (Dr. W. M. 

 (Ira ham} ; Sierra Leone Protectorate, Karma District, x.-xi. 1906 

 (Dr. H. E. ArbucMe) ; S. Nigeria, Oshogbo, i.-vi. 1910 (Dr. T. 

 F. G. Mayer} \ Ibadan (Capt. Leslie} ; British East Africa, Kenia 

 Forest, near Luchi River, 9. ii. 1911 (T. J. Anderson}', Xyasa- 

 land, Zomba (Dr. H. S. Stannus) ; Durban, 8. ii. 1902 (F. Muir}. 

 Besides these there are three female specimens with only three 

 bands on the eyes, but tvpical in other respects, from Sierra Leone 

 (J. Foxcroft} *T& from Obuasi, Ashanti, vii. 1907 (Dr. W. M. 

 Graham}. A female from Entebbe, Uganda, 1. x. 1904, has three 

 ocular bands, entirely black abdomen, and almost entirely black 

 scutellum, with only the hind border yellow. Finally, three 

 females, with three ocular bands, pale legs, and more or less yellowish 

 peristoma and facial tubercle, from Zungeru, X. Xigeria, 9. iii. 

 1911 (Dr. J. W. S. Mucjir] and Oshogbo, S. Nigeria, i.-iii 1911 

 (Dr. T. F. G. Hayer). 



90. Eristalodes barclsyi, sp. n. 



d $ . Length of the body 1415 mm. 



A very distinct species, w r ith 5-6 narrow ocular bands, sharply 

 striped thorax, and facial tubercle and edges of buccal cavity wholly 

 yellow. 



This rather large species recalls E. tceniops, from which it is at 

 once distinguished by the strongly striped thorax ; it is also allied 

 to E. macrops, Karsch, which has opaque thoracic stripes and a 

 black facial tubercle ; it seems also to have some affinity with the 

 Oriental E. an-orum, Fabr., which has also a yellow facial tubercle, 

 but has no bands on the eyes. 



Head black, covered with grey pollen on the occiput and yellowish- 

 grey pollen on the frons and face ; occipital upper border in the 

 female also pollinose, only narrowly shining near the eyes ; lower 

 orbits whitish grey ; vertical triangle of the male small, yellowish 

 pollinose, with dark hairs ; orbital border almost bare ; eyes in the 

 male yellowish red, opaque below, purplish shining above, and there 

 with broader facets and long brown hairs ; in the female the eyes 

 are entirely opaque with very short hairs above ; the dark bands 

 are narrow and show a tendency to break up into spots, chiefly 

 below, where they are attenuated ; there are also some black spots 

 on the hind portion ; in the male the line of contact of the eyes is 

 longer than the frontal triangle and twice as long as the vertical 

 triangle ; frontal triangle of the male rather small and convex, 

 densely yellowish pollinose, clothed with long dark hairs, which 

 become paler near the antennae ; there is sometimes a trace of a 

 black median line, which becomes yellow above the base of the
