the apices of the tibiae are clothed with thick fulvous pubescence. 

 Vogel's description gives no particulars whatever except the mention 

 of the smooth and broad lateral etytral margin, which some other 

 species also possess to a smaller or greater degree, and such de- 

 scriptions are worse than useless. My specimens vary in size from 

 6-8 millim. 



Chetsomela africana, sp. nov. 



Below obscure dark aeneous, above metallic dark green ; antennae 

 piceous, the basal joints flavous ; thorax sparingly and finely punc- 

 tured at the disc, more strongly so at the sides ; elytra with nine 

 rows of very regular punctures, the interstices minutely punctured. 



Length 6 millim. 



Of regular ovate and convex shape, the head scarcely punctured ; 

 the antennae piceous, the lower three joints fulvous, the terminal 

 joints broader than long ; thorax with the lateral margins nearly 

 straight, slightly narrowed towards the apex, the anterior angles 

 not prominent and but httle produced, the anterior margin straight 

 at the middle, the disc finely and very irregularly punctured, the 

 punctures of unequal size, the sides with deep and larger punc- 

 tures, the basal margin with a row of elongate deep punctures 

 at the sides ; scutellum impuuctate, aeneous ; elytra very regularly 

 convex, dark greenish, the punctures moderately large and arranged 

 in very regular rows, distinct to the apex, the interstices with a 

 few very minute punctures here and there, the lateral margins 

 impunctate ; underside and legs nearly black ; prosternum longi- 

 tudinally sulcate. 



Hah. Karkloof, Natal, on thistles ((?. Marshall). 



The sculpturing of the elytra in this species differs so much in 

 its regularity from any of those described by Vogel, that I must 

 regard the insect as distinct ; in nearly all of its allies the elytra 

 are partly regularly, partly irregularly punctured, or the rows are 

 geminate ; the insect is also of comparative small size, and the 

 colour of the head and thorax is more brownish aeneous, that of the 

 elytra greenish. 



Atechn-a inteeruptopasciata, sp. nov. (Plate XXII. fig. 11.) 



Black, thorax finely punctured at the disc ; elytra finely pune- 

 tate-striate, flavous, with three transverse black bands connected 

 with a lateral stripe, the first band curving upwards to the base, 

 the second and third bands connected near the suture, the latter 

 also narrowly black. 



Var. Thorax fulvous, with a V-shaped piceous central mark. 



Length 6-7 millim. 



Head extremely minutely punctured, flat; antennae rather feeble, 

 black, the basal joint flavous below, terminal joints not much 

 thickened ; thorax nearly three times broader than long, the disc 

 extremely minutely and sparingly punctured, the sides with some 

 Tery deep semi-confluent punctures ; scutellum smooth, greenish ; 

 elytra finely and regularly punctate-striate, flavous, with three
