GEN. PHYLLOCNEMA, Thorns. 



PHYLLOCNEMA GLOEIOSA. 



Plate VII. , fig. 1. 



Nigra, antennis, articulis ultimis duobus vel tribus exceptis, 

 pedibus anticis intermediisque rufis, posticis nigris, femoribus basi 

 rufescentibus ; caput antice rugosum, vertice profunde punctatum 

 antennas articulis quatuor ultirm's nonnihil ampliatis leviter serratis, 

 articulis duobus vel tribus ultimis fuscis ; prothorax ad medium 

 laterum aculeatus, intra basim transversim impressus, vix convexus, 

 crebre alveolatus ; elytra caeruleo-violaceis, prothorace triplo longiora 

 et basi ejusdem fere tertio latiora, humeris callo elevatis, in dorso 

 deplanata, rude coriacea, linea dorsali utroque vix distincta ; subtus 

 nigra, prosterno valde rugoso, pectore abdomineque sat crebre 

 punctulatis, illo lateribus pube albo-sericea vestitis, tibiis posticis 

 apicem versus foliaceo-dilatatis. Long. 21 rnm. ; lat. 6 mm. 



In comparison with P. mirifica, Pasc., its nearest ally, the dis- 

 tinctive characters are : (1) a wider prothorax, nearly hexagonal and 

 with a different sculpture ; (2) antennas with the joints more serrate 

 and the three apical joints more dilated these three joints are 

 mfuscate ; (3) foliation of the posterior tibiae about one-half the size of 

 that of P. mirifica (pi. vi., fig. IA) ; the colour is also different, the 

 under part, as well as the head and prothorax, being black instead of 

 caeruleous green, the elytra are also brighter purple-blue. 



Hab. Zambesia (Victoria Falls). Dr. Bradshaw. 



Phyllocnema (Callichroma) holubi, Dohrn., and P. pretiosa, Paring., 

 are evidently the same insect as P. mirifica, Pasc. 



PHYLLOCNBMIDA, nov. gen. 



A gen. Phyllocnema discrepat tibiis aiiticis intermediisque latioribus, 

 magis incurvis, infra carinatis, femoribus posticis multo brevioribus, 

 longe clavatis tibiisque posticis incurvatis, compressis, ad apicem 

 sat ampliatis, sed haud foliaceo-dilatatis.
