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. 
Two new species of African Eumastacinae (Orth.).

Brachytypus burri n. sp. 
Type: 2 ; 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.
