NeoloUius gen. n. 



Vertex square, the length in middle equal to width, apex and base 

 slightly concave; lateral carinae deep, those of apex and base small, 

 a small line but no carina down the middle ; the face between the medio- 

 lateral carinae projecting beyond the vertex ; face narrowest at base, 

 apical half roundly and broadly produced, side distinctly carinate, the 

 inner carinae near to the outer but distinctly raised above them 

 especially basally, face between inner carinae excavate, no median carina; 

 antennae small, globose, eyes without antennal emargination; pronotum 

 with two small depressions near the middle ; abdomen compressed ; hind 

 tibiae with two spines. Venation as in LoUiits Stal, the apical margins 

 of the tegmina truncate. This genus is a modification of Lollius, the 

 face is broader than long and in dorsal view there is a distinct break 

 between the square vertex and the produced face. 



Neolollius viridis sp. n. Figs. 8, 8a. 



Male. Length 6 mm., tegmen 6.6 mm. Light green; head, pronotum 

 and legs speckled with small, brownish marks, abdomen brownish below ; 

 tegmina with a few small, brown spots on hind margin and some faint 

 whitish ones scattered over the cells. 



Genital styles triangular, fattish, the acute apex turned in at right 

 angles; anal segment narrow, concave on ventral side, apex rounded, 

 anus about one-third from apex; aedeagus not dissected out. 



Described from two males from Tutuila, 900 to 1200 feet 

 elevation {Kellers, June 30, 1918). Type No. 1023. 



So far as my present knowledge goes there is a distinction 

 between the male genitalia of Flatidae. Ricaniidae and Issidae. 

 In the Issidae the aedeagus consists of a large outer tube 

 with or without complex appendages and a very small inner 

 tube without any complex appendages, and a fairly large 

 penis or lobe on which the gonopore is situated. In the 

 Ricaniidae the outer tube is large and has no appendages, 

 the inner tube small but with two large lateral appendages 

 and the penis is small. In the Flatidae the outer tube is small 

 with long appendages, the inner tube large without appendages, 

 and the penis is small.
