Lakes is passetl, and Commander Cameron, though his attention was 

 chiefly directed to geographical exploration, bears testimony to the 

 same fact. " To the west of Tanganyika a new geographical, ethno- 

 logical, zoological, entomological, and botanical region is entered." 

 ("Across Africa," vol. ii, p. 311). Unfortunately, the Kemiptera had 

 been preserved in sawdust impregnated with carbohc acid, which had 

 discoloured a large portion of the specimens, and rendered them some- 

 what difficult to determine. 



SCUTATA. 



The species belong to the East African fauna, with a slight amount 

 of variation in some cases from the typical forms. Sotea sichfasciata 

 and BracJiyplatys pallipes, found also in the Calabar district, were in 

 the collection, as was also the wide-ranging JEthus indicus. 



HOTEA SUBFASCIATA, Wcstw. & HopC, Var. 



This variety has its most constant character in the slightly pro- 

 duced and almost spineless condition of the lateral angles of the thorax, 

 and diverges only from the typical form in some specimens by a visible 

 serration on the anterior part of the lateral edges of the thorax, and 

 sometimes by a considerable increase in size. I do not, however, con- 

 sider any of these characters as sufficiently differentiated at present to 

 give them a specific character, as the type of suhfasciata in the Hope 

 collection at Oxford has the lateral angles of the thorax very slightly 

 produced, and in a long series of that species from W. Africa, I can 

 detect instances where the thoracic serration is also visible. Size too 

 is of little value, as in eight specimens I possess from Livingstonia, 

 scarcely more than two agree altogether in that respect. 



The real distinction between II. suhfasciata and II . gnmiice, the 

 other dominant African species, is the formation of the ventral seg- 

 ments, as pointed out by l)r. Stal in his " Ilemiptera Africana," and 

 drawings of which have most obligingly been forwarded to me by 

 Prof. Westwood. 



The East Asian species, H. curculionoides, H.-Schaff., follows the 

 same variation and wide range of habitat. It is recorded from Sumatra, 

 Malacca, Java, Timor, Celebes, Amboina, and China ; and of its varia- 

 bility in colour, Vollenhoven remarks, " L'individu lo plus clair en 

 couleur est de Java, le plus fonce est d'Amboine."
