the middle and of slightly oblique shape, another broad transverse 

 band occupies the apex of both elytra ; below black ; the legs 

 robust, flavous, as well as the presternum and mesosternum, the 

 former longer than broad, its base deeply concave, the sides raised 

 into narrow ridges. 



Hob. Port Alfred, South Africa (Rev. J. ONeil). 



Of this very pretty but small species I received a single example ; 

 like several of its congeners at present placed in this genus, the 

 eyes are not approached or contiguous, but the prosternum agrees 

 with the typical forms. 



ACHiENOPS (?) PTJNCTICOLLIS, sp. n. 



Yellowish white, the terminal joints of the antennae and the 

 breast and abdomen black ; thorax very closely punctured, with or 

 without piceous transverse bands ; elytra strongly and semi- 

 regularly punctate-striate, a spot on the shoulders and two near the 

 apex piceous or black. 



Var. Thorax without markings, underside flavous. 



Length 3-4 millim. 



Head broad, yellowish, strongly but not very closely punctured, 

 the vertex with a central black narrow stripe ; eyes broadly 

 emarginate ; antennas short and stout, extending to the base of the 

 elytra, the lower six joints pale flavous, the others black, terminal 

 joints, with the exception of the last one, dilated ; thorax more 

 than twice as broad as long, the sides rounded, the surface very 

 closely and strongly punctured, yellowish white, with a transverse 

 narrow piceous stripe at each side, sending off branches at right 

 angles to the anterior and posterior margin, another piceous spot 

 is placed at the middle of' the base, the basal margin likewise 

 narrowly black ; scutellum truncate at its apex, the latter flavous, 

 the base black ; elytra subcylindrical, pale yellowish, strongly 

 punctured in irregular rows, of which ten are placed on each 

 elytron, the sutural one being very short, near the apex some of 

 the rows unite in pairs, forming broader spaces between them, all 

 the punctures of piceous colours, a small piceous spot is placed on 

 each shoulder, two others more or less distinct are seen near 

 the apex, the inner one of which is placed rather higher than 

 the other spot ; legs pale flavous, the femora with a piceous spot ; 

 prosternum widened at the base, strongly punctured ; breast and 

 abdomen black. 



Hab. Dunbrody, Cape Colony, S. Africa (Rev. J. CNeil), on 

 mimosa-bushes. 



This little Cryptocephalus, of which I received two specimens, is 

 doubtfully placed by me in Achcenops, as the structure of the 

 prosternum does not agree with that genus, but 1 do not consider 

 it desirable to establish another genus on a single species. The 

 present insect has very nearly the general appearance of a 

 Pachybrachys ; the colour and the system of punctation is the 

 same, but the antenna? agree better with Monachus on account of 

 their shortness and the dilated terminal joints ; the prosternum
