256 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mai 4 . 6, 



Malacosoma variipes, sp. 11. 



The antennae, breast, and the legs black, the head and thorax 

 rufous, the latter impunctate, subquadrate ; elytra extremely finely 

 punctured, rufous ; base of the femora of the latter colour. 



Length 6 millim. 



Head rufous, impunctate, the froutal elevations transverse, the 

 carina acutely raised, labium black ; antenna extending below the 

 middle of the elytra, black, the third joiut one-half longer than 

 the second, the following joints more elongate, slender: thorax 

 one-half broader thau long, the sides feebly rounded before the 

 middle, the posterior angles strongly oblique, the posterior margin 

 rounded, anterior angles thickened, the disc impunctate, or with 

 some microscopically fine punctures, convex, rufous : scutellum 

 obscure piceous ; elytra widened posteriorly, convex, of the same 

 colour as the thorax, extremely closely and finely punctured ; the 

 breast, the apex of the femora, and the tibiae and tarsi black ; the 

 base of the femora and the abdomen rufous ; tibia; mucronate ; 

 prosternum very narrow, the anterior coxal cavities onen. 



Hah. Natal. 



Distinct from every other species of the genus in its system of 

 coloration. Quedenfeldt has described several species as Malacosoma 

 from Central Africa ; with one of them, M. defonnicome, the pre- 

 sent insect agrees partly in coloration but not at all in structure ; 

 and as Quedenfeldt makes no mention of the state of the cavities 

 nor the mucronate or non-mucronate tibiae, it is doubtful whether 

 he had a true Malacosoma before him ; his description agrees far 

 better with a species of Megalognaiha. 



LUPERUS MARSHALLI, Sp. n. 



Black, the antennae and the legs flavous ; thorax transverse, 

 obsoletely sulcate ; elytra with a few minute punctures. 



Length 4 millim. 



Head extremely finely granulate and punctured, when seen under 

 a strong lens, the frontal elevations verj r distinct, strongly oblique 

 and joined at the apex ; clypeus narrow, strongly thickened : antenna 1 * 

 nearly extending to the apex of the elytra, flavous, the second and 

 third joints short, equal, the apical four joints much constricted at 

 the extreme base ; thorax nearly twice as broad as long, the sides 

 straight at the base, feebly rounded anteriorly, the angles thickened, 

 the disc with a shallow transverse sulcus, very finely punctured, 

 black, shining; elytra slightly wider at the base than the thorax, 

 punctured like the latter, the punctures scarcely perceptible : 

 below black; the legs long and slender, all the tibiae mucronate, the 

 metatarsus of the posterior legs very long ; prosternum invisible 

 between the coxae, the anterior cotyloid cavities open. 



Hah. Estcourt, Natal, on acacia-trees (G. Marshall). 



Somewhat resembling our L. niger, but with entirely flavous 

 antennae and legs and the thorax with a shallow sulcus.
