NEW SPECIES OF PHYTOPHAGA 533 



tuation close and stronger than that of the thorax, below and 

 the legs pale fulvous, the posterior femora rather darker, their 

 apex piceous, metatarsus of the posterior legs half the length 

 of the tibia. 



Hab. Lago Bass Narok, Septemb. 1896. Many specimens. 



Not many African species of Longitarsus are known at present, 

 and only one from Abyssinia (L. fulviceps, Chap.) which differs 

 in having an impunctate thorax, black scutellum and piceous 

 breast and abdomen. 



10. Malacosoma tibialis, sp. n. — Testaceous, the antennae 

 (the basal joints excepted) and the tibiae and tarsi blackish, head 

 and thorax impunctate, elytra very finely punctured. 



Length 5 millim. 



Head impunctate, the frontal elevations very broad, strongly 

 raised and subtransverse, clypeus swollen, triangular, palpi fili- 

 form, antennae extending to the middle of the elytra, nearly 

 black, the lower three joints fulvous, the third joint one half 

 longer than the second, the following joints elongate, pubescent, 

 thorax transverse, one half broader than long, the sides straight, 

 the posterior margin rounded , the surface rather convex , not 

 perceptibly punctured , elytra slightly wider at the base than 

 the thorax, extremely finely and closely punctured, shining, tibiae 

 and tarsi black, presternum narrow, convex. 



Hab. Da Sancurar agli Amarr Burgi. Two specimens. 



There are now several unicolorous specimens of Malacosoma 

 known from Africa, the present one is another closely allied 

 form but may be known by the more transverse thorax and 

 the colour of the antennae, tibiae and tarsi, the species is less 

 than half the size of M. polita, Jac. which differs further in the 

 entirely black antennae and legs. 



17. Platyxantha Citernii, sp. n. — Elongate, fulvous, the anten- 

 nae, the apex of the tibiae and the tarsi black, head and thorax 

 with a bluish gloss, the latter bifoveolate, impunctate, elytra 

 metallic green, finely and closely punctured, abdomen purplish.
