Var. a. Posterior border of prosternum, mesostcriiura, and mctasternum, coxae, 

 trochanters, and base of femora, luteous. 



Mongo-ma-lobali. Isubu (W. Africa). 



Var. b. Similar to var. a, with the addition of two irregular black spots at the 

 base of the scutellum, divided by a central yellow fascia, wliich does not extend be- 

 yond the central elevated portion. Disc of abdomen beneath yellowish. Membrane 

 brassy-green. 



"Camaroons. 



Var. c. Two irregular and inconstant spots on the disc of the pi'onotum, which 

 in some specimens are linear, in others very waved and having almost the appearance 

 of being four in number ; in others they are amalgamated into one spot. A broad 

 band extends across the base of the scutellum and coria, dai'k bluish. On the under- 

 side the pectoral spots coalesce. The ground colour of this variety ranges from bright 

 yellow to purplish-red, and the membrane, generally pale ochreous, is, in some spe- 

 cimens brassy-green. 



Mongo-ma-lobah. Camaroons. 



Var. d. Head and pronotum dark bluish, the latter with an irregular median 

 reddish streak, extending from the anterior to the posterior borders, widening pos- 

 teriorly in some specimens. Scutellum and coria marked as in var. c. Abdomen 

 below with a sub-marginal row of four, somewhat rounded, spots, and an irregular 

 apical one, dark bluish. 



Mongo-ma-lobah. Camaroons. 



Bathtc(Elia distincta, n. sp. 



Sub-ovate, lateral angles of pronotum slightly prominent ; greenish-testaceous 

 above, thickly and finely punctured. Head and anterior half of pronotum pale 

 greenish-yellow, the last of which is much less densely punctured, and has a trans- 

 verse row of four greenish-testaceous spots. Antenna obscure olive-green, apex of third 

 and fourth, and apical half of fifth joint, black ; third joint longer than the second, 

 fourth and fifth equal. IMembrane brassy. Rostrum, legs, and under-side of body, 

 pale olive-green. Apex of rostrum pitchy. Tibiae setose. Long. 13 — 15 mill. 



Isubu. 



Apart from structural characters, its smaller size and the trans- 

 verse row of four spots on the anterior half of the pronotum, at once 

 distinguish B. distincta from the other three species of BathycoiJia at 

 present known to science.
