Mr. L. P^ringuey on new Coleoptera. 221 



outer margin and reaching the centre of the elytron ; the 

 mark of interrogation {vide Boheman's description) is reduced 

 to a mere dot, evidently the apex of the said marking ; the 

 sutural band and the apical marginal one connected with the 

 sutural line remain the same. These markings are of a 

 chalky white instead of the rich golden-yellow of the type. 

 From the Zambezi. 



Ophryodera rufo-marginata, Bohem., var. Oberthueri, 



A very large female specimen which I have seen in Mons. 

 Eend Oberthiir's magnificent collection is closely allied to the 

 preceding variety. 



It is larger, the sutural band is the same, the antemedian 

 band is similar to that of var. Bradshawij but the postmedian 

 macula is altogether missing, and the apical marginal band is 

 very narrow and ascends higher along the outer margin ; the 

 colour of the markings is also the same. 



I believe I have seen an example of this variety in Mr. H. 

 W. Bates's collection ; both these specimens were collected 

 by my friend the late Dr. Bradshaw near the Zambezi Kiver. 



Lastly, I have received from Northern Damaraland another 

 variety of this polychrome Cicindelid, which I intend to 

 describe shortly, and which unites all these varieties with the 

 typical insect described by Boheman. 



Graphipterus angolensis. 



Niger, eubnitidus; antennia elytrisque rufescenti-brunneis, fronte 

 prothoraceque utrinque albido-pubescentibus, hoc brevi, subcor- 

 dato; elytris subrotundatis, denudatis, striatis margine lateral! 

 albo-pubescente. 



Long. 10, lat. 6 mm. 



Head covered with a white pubescence ; prothorax cordi- 

 form, grooved in the centre, with the sides densely pilose j 

 elytra shaped like those of G. ferruginosus^ Chaud., some- 

 what more rounded in the female, denuded, with six raised 

 costae; costse and interstices strongly punctured, and with 

 the outer margin clothed with thick whitish hairs ; legs 

 reddish brown. 



Two examples from Angola. 



Graphipterus velox. 

 Niger, ovatus, pube supra cinereo-bruunea, eubtus albida tectue;
