with the second joint a little shorter than the third (remaining joints 
mutilated); pronotal angles produced into short, thick obtusely 
pointed spines. The corium is rather more greenish in hue than the 
head or pronotum. 
Long. : 8 millim. 
Hab. Niam-Niam (Bohndorff). 
Zangis guineensis var. 
ÆEdessa quineensis Fabr. Syst. Rhng. p. 151, 27 (1803). 
In a series of specimens collected at Niam-Niam, considerable 
variation occurs from the typical form of the species. In all of them 
the black markings of the upper surface are considerably dimi- 
nished, and the markings to the pronotum always faint and some- 
times obliterated. The two spots to the scutellum are generally 
present though small, but even these are sometimes absent. 
Zangis niamensis n. sp. 
Pale emerald-green; eyes, ocelli, rostrum, coxæ and a central 
narrow longitudinal fascia to abdomen beneath, pale brownish- 
ochraceous; antennæ green, second joint, apex of third joint, and 
fourth joint (excluding base) pale castaneous — apical joint muti- 
lated; extreme lateral margins of head, pronotum, base of corium 
and abdomen, very narrowly pale castaneous. 
Head thickly and somewhat coarsely punctate, antennæ with the 
third and fourth joints subequal in length, second longer than first, 
but shorter than third or fourth; pronotum and scutellum very 
coarsely and distinctly transversely rugose; corium thickly punctate 
and slightly rugulose, the lateral margins tranversely rugose; 
rostrum just passing the posterior coxæ. 
Long. : 16 to 17 millim. 
Niam-Niam (Bohndorff). 
The principal distinguishing character of this species is the pro- 
nounced transverse rugosity of the pronotum and scutellum. 
Cyclogastridea equatoria n. sp. 
Ochraceous unicolorous. 
Head with the lateral lobes coarsely punctate; antennæ with the 
second joint a little longer than the third which is sulcated near the 
apex, fourth joint sulcated for nearly its entire length. Pronotum 
finely and thickly punctate and subrugulose, the lateral margins 
slightly ampliated and convex,scutellum and corium finely punctate. 
Metasternal plate large, triangular, the lateral angles strongly 
produced, its posterior margin strongly grooved to receive short 
abdominal spine; abdomen with a short lateral streak of dark punc- 
tures on each segment near its lateral margin. 
Long. : 25 millim. 
Hab. Niam-Niam (Bohndorff).
