metallic blue, the interstices slightly wrinkled, the space near the 

 lateral margins deeply sulcate and flavous, this colour also 

 extending to the apical margins ; below and the legs fulvous, apex 

 of the posterior femora piceous, posterior tibia with a distinct spine ; 

 the metatarsus as long as the following joints together. 



Hob. Angola. 



Two specimens of this very well-marked and distinct species are 

 in my collection. 



Aphthona minuta, sp. n. 



Winged, entirely pale flavous or testaceous, the apical joints of 

 the antennae black ; thorax impunctate ; elytra scarcely perceptibly 

 punctured in irregular rows. 



Length 1 millim. 



Head impunctate, the frontal elevations distinct, bounded above 

 by oblique grooves, carina acute and rather narrow ; antennas two- 

 thirds the length of the body, the lower four joints flavous, tha 

 rest black, the second and third joints small, equal, the following 

 slightly longer, terminal joint more elongate and feebly thickened ; 

 thorax one-half broader than long, slightly narrowed in front, the 

 sides nearly straight, the surface somewhat depressed, with a very 

 obsolete transverse depression near the base, entirely impunctate ; 

 elytra scarcely wider at the base than the thorax, parallel, the 

 apex rounded, the surface with microscopically fine rows of 

 punctures ; posterior femora strongly incrassate, tibiae dilated at the 

 apex ; the first joint of the posterior tarsi as long as the following 

 joints together. 



Hah. Dunbrody, Cape Colony (Bev.J.O'Neil). Many specimens. 



One of the smallest species of the genus, perhaps most nearly 

 allied to the European A.pallida, but of entirely uniform coloration 

 with the exception of the antennae ; the penis is of parallel shape 

 neither constricted nor widened, and with the apex broadly 

 rounded, ending in a small point. 



Serraphula elongata, sp. n. 



Elongate, narrowed posteriorly, piceous below, above greenish 

 aeneous, the antennae and the legs (the posterior femora excepted) 

 fulvous ; thorax coarsely and closely punctured ; elytra closely 

 punctate-striate, the interstices longitudinally costate. 



Length 2 millim. 



Head impunctate, the frontal elevations trigonate, undivided; 

 the clypeus strongly raised into a triangular ridge, which extends 

 upwards between the antennae ; palpi rather slender ; antennae 

 extending to the apex of the elytra, fulvous, the basal joint 

 moderately long and stout, the second and third short, equal, the 

 following joints gradually elongate and slightly thickened ; thorax 

 subquadrate, one-half broader than long, all the margins straight, 

 the angles not produced, the surface closely and strongly punctured ; 

 scutellum broader than long ; elytra rather long and convex, slightly 

 wideued towards the middle, rather pointed towards the apex, the
