which it forms galls. In 1916 Van der Goot erected his Schizoneura- 

 phis with gaUorum V. d. Goot as type. This species was said to 

 form galls on Distylium stellare. 



The genus Astegopteryx can be separated as far as the recognized 

 forms are concerned by the proportion of the antennal segments 

 and some variation in the shape of the stigma. These differences 

 are not, however, of large importance and Nipponaphis should be a 

 synonym of Astegopteryx. In the same way, the type of Van der 

 Goot's genus is not sufficiently different to warrant the erection of 

 a new genus and Schizoneuraphis also should be considered asynonym. 



Characters. — Cornicles broad rings; apterous form 'with five-segmented antennae; 

 alate form "with five-segmented antennse which are armed with annular sensoria. 

 fore wings with the media once branched; hind wings with both media and cubitus 

 present. Stigmal vein arising rather far back on the stigma. Cauda rounded, anal 

 plate somewhat bilobed; forms living in galls. 



Sexual forms unknown. 



Type (mono typical), Astegopteryx styracophila Karsch.

 tions. Antennse of four segments: cauda and anal plate both rounded. Winged 

 orms unknown .

 Plate XV, H-K. 



1916. Glyphinaphis Van der Goot, Zur Kenntniss der Blattlause Java's, p. 232. 



Characters. — Cornicles present as mere pores; antennae of four segments which are 

 armed with linear sensoria. Fore wings with the media once branched; hind wings 

 with both media and cubitus present; cauda knobbed; anal plate rounded; body 

 covered with stout hairs. 



Type (fixed by V. d. Goot, 1916), Glyphinaphis barnbusae V. d. Goot. 



Genus MANSAKIA Matsumura. 

 Plate XV, L. 



1917. Mansakia Matsumura, Synopsis of the Pemphigidae of Japan, p. 59. 



The author of the genus Mansakia stated that it is closely allied 

 to Hormaphis, but it would appear to the writer to be related to the 

 genera in the Oregmini as understood in the present classification. 

 The presence of the cornicles would indicate that the genus is not 

 related as closely to Hormaphis as to Astegopteryx, but its host and 

 the nature of the gall would place it close to Hamamelistes. Since 

 all of the forms are not known it is impossible to state positively 

 its position.
