and closely punctured, elytra flavous, very closely and irregularly 

 punctured, a narrow sutural and a still more narrow lateral and 

 ajDical margin, greenish-l)lack. Length 2 millim. 



Head closely and finely punctured, with small and smooth frontal 

 elevations, clypeus rather convex, widened in front, impunctate, 

 antennfo robust, black, the lower three (sometimes two) joints flavous, 

 the second, third and fourth joint equal, the fifth slightly longer in 

 the male, terminal joints thickened ; thorax one-half broader than 

 long, greenish-black, strongly and closely punctured ; elytra slightly 

 wider at the base than the thorax and of similar punctuation, the 

 dark sutural band narrowed at the base and apex, the lateral bands 

 of about half the width, the shoulders sometimes likewise with a 

 small spot ; the male organ is of slender, parallel and sliglitly curved 

 shape, broadly rounded at the apex, the latter ending in a small 

 point at the middle. 



Hah. DuNBRODY, Cape Colony {Rev. ffNeil). 



This species is perhaps more nearly allied to P. parallela, 

 Boisd., thaa to any others, it is of the same size and 

 coloration but the sutural band is not so broad and much 

 narrower at the base and apex ; the shoulders have only a 

 very small spot occasionally and the male organ is pointed 

 at the middle instead of broadly rounded. 



Grepidodcra (Derocrepis) acuvmiata, sp. n. 



Narrowly elongate, pointed posteriorly, apterous ; lower joints of 

 the antennae, the head and thorax fulvous, elytra bark blue, strongly 

 punctate-striate, the interstices minutely punctured, anterior and 

 intermediate legs fulvous, posterior ones and the breast and abdomen 

 black. Length 2 millim. 



Of posteriorly pointed shape, the head impunctate, rufous or 

 fulvous, obliquely grooved between the eyes, frontal elevations rather 

 small, trigonate, labrum piceous, antennae about half the length of 

 the body (taken as a whole), the lower seven joints flavous, the others 

 blackish, the second to the fourth joint of equal length, fifth joint 

 slightly longer, penultimate three joints short and thicker, apical 

 joint more elongate ; thorax about one-half broader than long, the 

 sides rather strongly deflexed anteriorly, the lateral margins feebly 

 rounded, the angles not very marked, basal sulcus straight and deep, 

 boixnded at the sides by an equally deep perpendicular groove with 

 high lateral ridges, the disc only perceptibly punctured when seen 

 under a strong lens, scutellum black, broader than long ; elytra 

 scarcely widened at the middle, pointed at the apex, metallic-blue, 

 closely and strongly punctate-striate, the interstices very finely and
