Of most interest is a male Rihana similaris Grossbeck, from 

 Bainbridge, Ga., September, 1910. The only other recorded 

 specimen is the type from Fernandina, Florida, in the collec- 

 tion of the United States National Museum. This species 

 closely resembles Rihana lyricen, but differs greatly in the 

 genitalia of the male. We also note the longer opercula, 

 which extend to the third abdominal segment as mentioned in 

 the original description. In the Georgia specimen the inner 

 half of each operculum is dark colored and the band of black 

 on the ventral surface of the abdomen is broader than in any 

 of the lyricen examined.

Type: 5 ; Mossamedes Province, Angola. Acad. Nat. Sci. 

 Phila., type no. 5184. 



Closely related to B. insularis Burr* from Sokotra, but dif- 

 fering in the much larger size and proportionately smaller pro- 

 notum. From the remaining species of the genus, B. rotundi- 

 frons (Burr) from Mombasa, the new form can readily be 

 separated by having the metanotum exposed. 



Size medium; form strongly compressed. Head well seated in the 

 pronotum; vertex very steeply declivent and gently passing into the 

 frontal costa, lateral margins of same slightly compressed dorsad of 

 insertion of antennae and regularly converging ventrad of the same, 

 frontal costa and contiguous portions of vertex rather deeply sulcate; 

 antennae hardly longer than the eye, eleven-jointed; eyes subovate in 

 outline, slightly longer than the infra-ocular portion of the genae, not 

 at all prominent. 



Pronotum with the greatest length contained nearly one and one-half 

 times in the greatest (caudal) depth of same; dorsal carina moderately 

 arcuate, ascending caudad ; cephalic margin obtuse-angulate, caudal 

 margin moderately emarginate mesad ; lateral lobes with the ventral 

 margin oblique sinuate, ventro-cephalic angle very faint, ventro-caudal 

 angle marked, nearly rectangulate, caudal margin of lobes slightly 

 arcuate dorsad and ventrad, nearly straight in the middle.
