 6-5-6-7 mm. Rostrum, segment I, 1 -6-1-8 mm., II, 1 -6-1-8 mm., Ill, 0-9-1-0 mm., IV, 

 0-7-0-8 mm. Pronotum, length, 2-6-2-8 mm., width, 2-65-2-80 mm. Hind femora, 7-2- 

 7-4 mm. Hind tibia, 7-8-8-0 mm. Distance between ocelli, 0-45-0-55 mm., distance between 

 an ocellus and an eye, 0-75-0-85 mm. 



Usually slightly more robust than o" ; posterior margin of seventh abdominal sternum emar- 

 ginate, with a very small median projection (Text-fig. 306). 



$ genitalia : First gonocoxae broad, outer margin sinuate (Text-fig. 247) ; eleven pairs of 

 intervalvular sacs (Text-fig. 304) ; spermatheca elongated with a median flange and a short 

 coiled tube of different thicknesses (Text-fig. 233). 



Holotype^, Philippine Islands : North Luzon, Los Bafios, 21.1.1914 (G. Bottcher) 

 B.M.(N.H.). 



Paratypes. 1 <$, 4 $, with some data as holotype, B.M.(N.H.), North Luzon, Los 

 Bafios, 1 3, (P. I. Baker), Mus. Hels., 1 <$, without any date, Riksmus. Stockholm, 

 Luzon, Mt. Maquiling, Elev. 50 m., 3.1X.1949 (Boscos), Moravian Mus., Berne. 



This species is probably localized in Philippine Islands and has not been found in 

 any other part of Oriental regions. Adults have been collected in the months of 

 January and September. 



This species is closely allied to another, slightly more widely distributed species, 

 L. tagalica, and shares the characters of black apices of femora, and bases of tibiae 

 and tarsi ; however the <$ can easily be separated by very short and pointed blades of 

 claspers (very long and cylindrical in tagalica) and the $ by small, convex median 

 projection of seventh abdominal sternum (a large median projection in tagalica) and 

 by first gonocoxae curved near apices. This species can be separated from all other 

 species of this genus by long apical antennal segments, which are at least as long as or 

 longer than second and third together. 



Leptocorisa luzonica sp. n. 



(Text-figs. 208, 222, 236, 250, 264 and 308-314) 



Characterized by small body, straight and blunt paraclypeae and by the form of $ 

 and $ genitalia.

Species of small size, pale, unicolourous. Head comparatively short, occipital suture rather 

 invisible at sides (Text-fig. 309) ; paraclypeae straight, thick at base, with rounded apices.
