slender, testaceous, tlie terminal joints slightly stained at the apex 

 with piceoi;s, third joint slender, slightly curved and widened at the 

 apex ; thorax about twice as broad as long, slightly constricted at the 

 base, the transverse sulcus deep and nearly straight, the surface with 

 a few fine punctures, elytra wider at the base than the thorax, nearly 

 parallel, extremely closely and finely punctured, their epipleurai 

 broad at the base but nearly disappearing below the middle, legs 

 slender, the metatarsus of the posterior ones as long as the following 

 three joints together, claws bifid. 



Hal. German East Africa. 



I only know tlie female sex of this species, in which the 

 last abdominal segment has a small triangular emargination 

 at the middle ; the shape of the third joint of the antennae,

 characteristic mark of the insect as well as the black

Exosoma {Malacosoimt) slicppardiy sp. n. 



Black, head and thorax fulvous, the latter sidjquadrate, finely 

 punctured, elytra subcylindrical, black or dark fuscous, punctured in 

 very closely approximate, serai-regular rows. Length 6 millim. 



Head broad, impunctate, the frontal tubercles broadly, transversely 

 trigonate, clypeus triangular, antennae with somewhat short, sub- 

 triangular joints, l>lack, the second and third joint short, subequal ; 

 thorax subquadrate, scarcely one-half broader than long, all the 

 margins feebly rounded, the angles distinct but not produced, the 

 disc convex, fulvous, very minutely and closely punctured, scutellum 

 small, black ; elytra of a dull fuscous black colour, sometimes witli 

 a pale ground colour shining through, more strongly punctured 

 than the thorax, the punctures at the base somewhat regularly 

 arranged in closely approached rows ; under-side and legs black, 

 clothed with fine yellowish pubescence, all the tibiai distinctly 

 mucronate. 



Hah. Matopas, Rhodesia {P. A. SJieppard). 



A rather large-sized species and quite typical pf the 

 genus, the prosternum extremely narrow and convex, all 

 the tibiae mucronate and the anterior cotyloid cavities 

 open. 



ExosoTiia {Malacosoma) stnrnii, sp. n. 



Narrowly elongate, black, the clypeus, femora and tibite fulvous, 

 thorax impunctate, fulvous, elytra finely punctured and wrinkled, 

 flavous, a sutural band at the base and another broader band at the
