2. On Kuri, Castanea saliva Mill., Nishigahara, Tokyo, Oct. 

 2, 1913. Collection number 106. In this lot were a large 

 number of specimens which were apparently mature, but 

 their wing pads, while almost perfect in structural details, 

 were very small and rudimentary as if the development 

 had been suddenly and permanently retarded. 



Myzocallis, species 



Of the five winged viviparous females of this very interesting 

 species not a single one possessed a complete antenna necessary 

 to complete determination. The species is pale green, small, 

 about the size of Myzocallis quercus (Kalt.) which it resembles 

 in wing venation. The four or five pairs of abdominal tubercles 

 are concolorous with the abdomen; there are four very long 

 spines on the front of the head and five or six shorter knobbed 

 spines on the inside margins of antennal articles I-III ; basal half 

 of III with three sensoria. A single apterous viviparous female 

 shows the filament of the antennal article VI to be about twice 

 as long as the base. The body is covered with long knobbed 

 spines. 



Host plant — Taken on the undersides of the leaves of 

 Kunugi, Quercus serrata Thunb. 

 Locality — Nishigahara, Tokyo. 

 Date of collection — May 15, 1913. 

 Collection number — 41. 



Myzocallis, species* 



A single winged viviparous female with parts of both an- 

 tennae missing. The color is pale green with the antennae pale, 

 the legs green with the tips of the tibiae and the entire tarsi 

 dusky. The antennae of a nearly matured winged nymph has 

 the base of VI 0.10 mm. and the filament 0.4 mm. long; 

 article III, though partly missing, has 11 sensoria on the full 

 length. Wings pale with a noticeably short radial sector. 



* The species on bamboo described as Takecallis bambusd Mats, appears to be 

 the species described as Myzocallis arundicolens (Clarke). It is common at Berkeley, 

 Cal.
