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 Distyliurn sieUare. 
The genus Astegoptervx 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 Astegoptervx. 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 a synonym. 
Characters. — Cornicles broad rings; apterous form with five-segmented antennae; 
alate form with five-segmented antennae 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 (monotypical) , Astegopteryx styracophila Karsch.

tions. Antennae of four segments; cauda and anal plate both rounded. "Winged

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.Y. d. Goot, 1916), Glyphinaphis bambusae V. d. Goot. 
Genus MANSAKIA Matsumura. 
Plate XV, L. 
1917. MansaUa 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.
