middle, and a spot near the apex blackish,", the suture likewise 

 narrowly black ; below fulvous, the legs black, the femora more 

 or less fulvous at the base ; prosternum narrow, mesosternum 

 transversely subquadrate. 



I fab. Zongo, Mokoanghay, Congo. (Coll. Belgian Mus. and 

 my own.) 



Of this singularly marked species I received two exactly similar 

 specimens from the Belgian Museum. The eyes are more ovate, 

 less reniform, and more deeply notched than is generally the case 

 in Plagiodera, and the whole appearance of the insect resembles 

 more Ghrysomela, but the shape of the thorax and the short dilated 

 antenna? as well as the prosternum agree with Plagiodera : the 

 elytral bands scarcely justify this expression, as they consist of 

 longitudinal irregular-shaped marks partly connected. 



MELASOMA QUADR1LINEATUM, Sp. n. 



Testaceous, head piceous, closely punctured ; thorax with three 

 longitudinal bands, very closely punctured ; elytra strongly and 

 irregularly punctate, the sutural and lateral margins, as well as two 

 longitudinal stripes, black. 



Length 6 millirn. 



Of elongate shape, somewhat depressed ; the head very closely 

 and finely punctured, piceous, the parts of the mouth paler ; 

 antennae very short, testaceous, the apical joints darker, slightly 

 thickened ; thorax twice as broad as loug, narrowed in front, the 

 sides rounded, the surface punctured like the head, the sides with 

 a small fovea, the middle of the disc with a broad longitudinal 

 band, the sides with an elongate oblique spot, black ; scutellum 

 impunctate, black; elytra more strongly punctured than the 

 thorax, the punctures here and there arranged in irregular rows, 

 more closely placed and of larger size at the sides, these with a 

 narrow longitudinal costa placed near the lateral margin, a narrow 

 longitudinal stripe placed on the shoulders and nearly extending 

 to the apex, preceded by a similar stripe, as well as the sutural and 

 lati-ral margins narrowly, blackish ; below and the legs testaceous. 



Hab. Matabeleland, near Tati. 



Of this well-marked species, quite distinct from any of its 

 African congeners, a single specimen is contained in my collection. 



Halticin E. 

 Phyllotreta capensis, sp. n. 



Dark bluish or greenish aeneous, the basal joints of the antenna' 

 and the tibia? and tarsi fulvous ; head and thorax strongly and 

 closely punctured ; elytra seini regularly punctate-striate, the 

 interstices sparingly and minutely punctured. 



Length 2 millim. 



Head very finely and closely punctured ; the clypeus entirely 

 contiguous with the face, rather convex and broad, punctured like 

 the head : antennae not extending to the middle of the elytra,
