152 THE ENTOMOLOGIST. 



Face strongly, deeply punctured, the part in the centre below 

 between the furrows finely, closely punctured ; the lower part of the 

 sides of the front is smooth, with two or three large punctures in the 

 centre ; the upper is closely, transversely punctured ; the central de- 

 pression smooth, its upper part coppery tinted ; the ocellar region is 

 sparsely, weakly punctured and coppery tinted, tlie rest of the vertex 

 is more strongly punctured. Upper orbits above weakly, below 

 strongly punctured. Prothorax smooth. Mesonotum covered strongly 

 with round deep punctures, the edges of the punctures sharply raised ; 

 down its centre is a dark violaceous band which becomes narrowed 

 towards the apex. The punctuation on the scutellum is closer and 

 runs into longitudinal striae, the apex is closely, transversely striated. 

 Metanotu.m in the narrowed centre with some striee, the dilated sides 

 depressed, smooth. Mesopleurge strongly punctured above, more 

 weakly below ; the furrow at the base is widened and curves obliquely 

 downwards ; this down branch is wider than the longitudinal one and 

 is smooth ; on the apex the punctuation is finer and closer, and runs 

 into striae, this posterior part being separated from the rest by a 

 shallow furrow. Back of abdomen smooth, the sides finely acicu- 

 lated. 



Pentachalcis, gen. nov. 



Hind femora with three large and two small teeth. Middle tibiae 

 without spurs. Antennae (including the ring-joint) twelve-jointed. 

 Apex of scutellum with a distinct bluntly rounded projection, of 

 which the sides and apex are clearly raised above tlie basal part. 

 Metanotum untoothed, but with a small rounded projection on the 

 lower part of the sides. Malar space long, nearly as long as the 

 eyes. Abdomen sessile, not truncated at the base. Hind coxae 

 almost as long as the femora, which are longish oval ; the penulti- 

 mate joint of the hind tarsi is as long as the preceding two united, 

 and is thicker than tliem ; the femora extend beyond the apex of the 

 abdomen. The antennae are placed distinctly above the lower part of 

 the eyes ; the scape extends above the vertex. Marginal and post- 

 marginal veins long, the latter much thickened ; the stigmal branch 

 short, thick. 



Comes near to Pseudochalcis, Kirby. Pentachrysis is the 

 sole described genus in the group with only five teeth on hind 

 femora. 



Pentachalcis erythronota, sp. nov. 



Black ; the mesonotum and scutellum bright red ; the four 

 anterior knees, the base and apex of the four front tibiae, and all the 

 tarsi of a duller, more testaceous red. Hind femora with three 

 longish, clearly separated teeth on the base, and two short stumpy 

 ones on the apex, the apical of which is broader than the j)enultimate. 

 Wings almost hyaline, the apex broadly fuscous violaceous ; the ner- 

 vures black. Basal three antennal joints bare, shining ; the others 

 opaque, thicker, covered with a microscopic down, the fourth slightly 

 but distinctly longer than the fifth. Face strongly, deeply punc- 

 tured, more or less reticulated ; in the centre of the face is a longi- 

 tudinal keel, equally distant from the top and bottom ; the vertex 

 and sides of the front are similarly punctured-reticulated, as is also
