band ; scutellum rounded at the sides, more or less piceous or 

 greenish ; elytra very strongly punctured in rather irregular 

 rows, closely placed, which are here and there nearly confluent 

 below the shoulders, the ground-colour liavous with the following 

 dark greenish spots — an elongate spot on the shoulders, a small 

 one near the scutellum, four elongate spots placed transversely 

 before the middle, two others rather larger immediately below 

 the latter, and two smaller spots near the apex (one near the 

 margin, the other near the suture), posterior portion of the 

 suture likewise narrowly greenish or brownish ; elytral epipleurae 

 with a short row of punctures at the base : underside and legs 

 flavous, iuipunctate, aU the femora armed with a distinct 

 tooth ; prosternura broad, the sides thickened, the disc finely 

 punctured. 



Hah. Niger-Benue Expedition (Staudinger). Mv collection. 



A well-marked and distinct species, of which I have received 

 three specimens from Dr. Staudinger. The markings of the thorax 

 and the spots of the elytra differ in the specimens in size and partly 

 in shape, and it is quite possible that they may occasionally form 

 longitudinal bands. Like the other species of the genus, the eyes 

 are surrounded by a narrow sulcus. 



Ehembastus imitaks, n. sp. 



Pale fulvous or testaceous, the apical joints of the antennse and 

 the knees piceous ; thorax sparingly punctured ; elytra distinctly 

 punctate-striate, the sutural and lateral margins, a round spot at 

 the base, and an elongate one at the middle of each elytron 

 greenish aeneous. 



Length 1 line. 



Head impunctate, the vertex often dark aeneous, lower portion 

 of the face with a few minute punctures, the clypeus not separated 

 from the face ; eyes surrounded by a very narrow sulcus ; antennae 

 extending to the middle of the elytra, fulvous, the terminal five 

 joints nearly black, slender and elongate; thorax transversely 

 convex, twice as broad as long, the lateral margins A'ery slightly 

 rounded, the disc with some remotely placed punctures, which do 

 not extend to the base or the sides, the anterior margin sometimes 

 aeneous at the middle ; scutellum ovate, greenish seneous ; elytra 

 with a rather feeble depression below the base, distinctly punctate- 

 striate anteriorly, the punctures much finer towards the apex, 

 the lateral margin accompanied by a row of deep punctures, 

 narrowly greenish aeneous as well as the suture, a round spot 

 at the base and a short stripe at the middle of the disc greenish 

 aeneous : underside and legs pale fulvous, the knees darker ; 

 femora armed with a tooth ; prosternum impunctate.

In coloration this species almost resembles B. variabilis, Har. 

 (=4c-notata, Lefev.), but is less than half the size and has 

 the elytral punctuation much finer ; the antennse also differ in
