before him in whicli the white colour of the clypeus &c. had become 

 discoloured. The variety I mention has not been noticed bj^ Suffrian, 

 and my description of the spotted form is considered by him to 

 represent a rare variety : that the Xatal insect may, however, prove 

 to be of another closely allied species is not impossible. 



Cryptocephaltjs tTNiciNCTtrs, n. sp. 



Black, the base of the antennae and the tibiae more or less fulvous; 

 thorax very minutely punctured, fulvous, with more or less confluent 

 black bauds ; elytra strongly punctate, the insterstices finely punc- 

 tured, fulvous, the margins narrowly and a short lateral stripe 

 black. 



Length 2 hnes. 



Head strongly rugose and finely pubescent, black ; antennae 

 extending beyond the middle of the elytra, black, the lower five 

 joints fulvous, the second and third joints short, nearly equal, 

 terminal joints rather elongate, shorter in the female as well as 

 the entire antennae ; thorax strongly narrowed in front, the sides 

 but slightly rounded, the disc very minutely and irregularly 

 punctured, reddish fulvous, the sides occupied by two broad black 

 bauds of variable width, often connected with another small black 

 spot near the margin, but as frequently separated from it and 

 narrower ; scutellian not longer than broad, black ; elytra with 

 deep rows of slightly transversely-shaped punctures, the interstices 

 also with a single row of minute punctures, the basal, sutural, and 

 lateral margins (the latter at the posterior portion only) black, the 

 surface pale fulvous, with a short black band from the shoulder to 

 below the middle placed between the seventh and ninth rows of 

 punctures ; underside and pygidium black, finely pubescent ; the 

 presternum, mesosternum, and a spot between the posterior coxae 

 yellow ; legs black, the tibiae more or less fulvous at the base and 

 apex. 



Hah. Natal, Estcourt {G. Marshall). 



The single elytral stripe at the sides and the rugose and black 

 head, as well as the other details pointed out, will separate this 

 species from any of its African congeners. 1 have seen four speci- 

 mens only, varying in the amount of black on the thorax and legs. 



Cktptocephalus bimactjlicollis, n. sp. (Plate XVII. fig. 12.) 



Fulvous, thorax impunctate, the disc rufous, the margins flavous, 

 the base with two black spots ; elytra finely punctate-striate, yellow, 

 a transverse band at the base and a narrower one near the apex 

 black. 



Length 2 lines. 



Head with a few fine punctures, the vertex fulvous or piceous, 

 the lower portion flavous ; labrum and palpi testaceous ; antennae 

 extending to the middle of the elytra, shorter in the female, the 

 lower five or six joints flavous, the others fuscous, third joint 

 but slightly longer than the second, terminal joints elongate: 

 thorax strongly narrowed in front, the sides nearly straight, the
