Klappan is in Xorthern Formosa, Horisha and Mt. Ari in 

 Central Formosa. 



Herpts. 



(1) H. hniniu'd sp. n. { $ 9 ). 



$ Light brown, darker on scutellum, abdomen and genitalia. Teg- 

 mina light brown, veins slightly darker; wings light fuscous with 

 brown veins. 



Pygophor with ventral and lateral edges straight, ventral surface 

 with a median, transverse, broad, depression making it concave in 

 lateral view; anal segment fairly large, longer than broad, sub-lan- 

 ceolate in dorsal view, the apex rounded, anus situated about middle 

 on ventral f<hJe, anal style arising from beneath apex of segment, ilat- 

 tened, broadened from base, apex produced into two fine points with 

 acutely angular emargination between, bent ventrally from about mid- 

 dle; genital styles large, narrowest at base, roundly emarginate near 

 apex, a ridge running from the inner rounded apical corner to outer 

 edge near base; penis very large and complex. 



5 , The female I associate with this male is the same in size and 

 color. The abdomen and styles darker brown. Pregenital ventral 

 plate angularly and evenly produced from sides, with the apex round- 

 ed; anal segment small. 



There is another female specimen larger and darker in color 

 which may be the rightful spouse of this male. In it the pre- 

 genital plate is evenly and angularly produced, the apex round- 

 ed, a deep transverse constriction runs across the middle, the 

 plate in the middle, anterior of the constriction, elevated into 

 a rounded knob ; anal segment small with anus on ventral side, 

 anal style flattened, rounded at sides and angularly emarginate 

 at apex. The shape of the anal segment and style would indi- 

 cate that this is the true female, but the size and color is in 

 favor of the other. 



Length of type 2.5 mm. ; tegmen 4 mm. 



Length of second female 2.75 mm. ; tegmen 5 mm.
