Museum of Comparative Zoology at Cambridge, Massa- 
chusetts (type no. 23,393) ; allotype in coll. Straneo. 
This new species is closely allied to Abaris aenea Dej. and 
notiophiloides Bates by the lack of a scutellary stria and by 
the lateral margin of the pronotum distinctly reflexed near 
the basal angles. Compared with A. aenea Dej. the 3rd 
interstice of elytra is wider (nearly as wide as in notio- 
philoides) and the lateral margin is a little less reflexed 
near the base : compared with A. notiophiloides Bates, the 
legs are ferrugineous and the femora darker (in notio- 
philoides, flavo-testaceous) and the base of the pronotum 
is punctured only near the basal foveae (in notiophiloides, 
also in the basal part of lateral margin) .
