the middle of the elytra, flavous, the terminal joints more or less 

 fuscous, basal joint elongate and slender, the second and the 

 following joints of equal length ; thorax twice as broad as Ions', 

 slightly narrowed in front, the sides nearly straight, with a narrow 

 reflexed margin, the anterior angles thickened, basal margin 

 unaccompanied by an impressed line, the surface finely and closely 

 punctured ; elytra ovate, pointed posteriorly, their base not 

 wider than the thorax, strongl}'^ and closely punctate-striate, the 

 interstices longitudinally cosrate at the sides and at the apex : 

 underside and legs piceous, the tibiae and tarsi more or less flavous ; 

 prosternum narrow, longitudinally sulcate.

Ch^tocnema caeinata, sp. n. 



Greenish black below, the basal joints of the antennae and the 

 tibiae and tarsi fuh'ous ; above metallic green, the head ^ith three 

 transverse ridges, thorax finely punctured ; elytra strongly punctate- 

 striate, the interstices finely wrinkled. 



Length 2-2| millim. 



Head rather elongate, perpendicularly deflexed, dark greenish, 

 strongly and remotely punctured and minutely granulate at the 

 lower portion ; the clypeus deeply triangularly emarginate, the 

 vertex with three acute transverse ridges, its base strongly rugose ; 

 the antennae scarcely extending to the middle of the elytra, fulvous, 

 the apical joints more or less fuscous, the third and fourth joints 

 equal, but little longer than the second joint ; thorax very short, 

 nearly three times broader than long, the sides scarcely rounded, 

 obliquely narro\^'ed towards the apes, the surface finely and rather 

 closely punctured and minutely granulate, metallic light green, the 

 anterior and posterior margins accompanied by a finely impressed 

 groove or line ; scutellum much broader than long, cupreous ; 

 elytra not wider at the base than the thorax, strongly punctate- 

 striate, the punctures very closely approached, the interstices 

 slightly convex and very finely transversely wrinkled, the space 

 between the first row of punctures and the suture irregularly 

 punctate; below nearly black, with a slight metallic greenish gloss,

This species is doubtless very closely allied to C. cristata Har. 

 from the Zambesi Eiver ; but the latter insect is described as 

 greenish aeneous, and as having a single transverse ridge at the 

 vertex of the head, while here there are three and the space behind 

 these ridges is strongly rugose. The size of v. Harold's species 

 is also smaller, other details of structure are not given.
