 defensive discharge of the Bombardier Beetle and many other 

 Carabidae, and for the use of suffocating or irritating secretions 

 generally, but was a most inappropriate term by which to 

 express a concealing coloration. 



BUD-AND-FLOWER-LIKE FLATIDAE (HOMOPTERA) FROM EX- 



German East Africa. — Prof. Poulton exhibited beautiful 

 examples of the green bud-like Ityraea speciosa, Melich., and 

 the many-coloured flowerdike /. nigrocincta, Walk., collected 

 by Mr. A. Loveridge at Mrogoro, on the Central Bailway, 

 about 100 miles W. of Dar es Salaam; also specimens of the 

 orange-red, flower-like /. gregoryi, Dist., taken at Kibwezi, 

 British East Africa, by Mr. W. Feather. All these specimens, 

 which had been kindly sen,t by Mr. E. C. Chubb of the Durban 

 Museum, were bright and fresh and gave an unusually striking 

 impression of the bud-and-flower-like appearance. 



The flower-like nigrocincta were, in the resting position, 

 scarlet anteriorly, passing into a narrow zone of orange 

 followed by a broad one of very pale blue, and this by a 

 still broader terminal area of very pale ochreous. The fore- 

 wings of the green speciosa were encircled, except near the 

 hinge, by a narrow red line enclosed within a narrow marginal 

 black one, with a much stronger development of both red 

 and black on or near the costal border, accompanied by 

 bright yellow markings and a vivid bluish green modification 

 of the ground-colour. In spite of the obvious differences 

 between the patterns there were resemblances between the 

 black markings which suggested, as Mr. Loveridge believed, 

 that they were the dimorphic forms of a single species ; and 

 the same element in the pattern rendered it probable that 

 the more northern gregoryi was the flower-like form of another 

 dimorphic geographical race of the same species, separated 

 In mi the southern race by colour differences only. 



Among other interesting observations on the Ityraea made 

 in 1917-18 in the ravine of the river at Mrogoro. Mr. Loveridge 

 noticed that the green forms were much rarer at first about 

 1 to 11, later 1 to 10- and much easier to catch than the 

 blossom-like forms. The latter were often found in cop. : 

 once the two different forms were thus taken, and on the
