near Callipterina of course, but distinct from it and in no way connected with Lach- 
nina. It might for the present be called Phyllaphidina and defined thus : — 
Body furnished with rows of ‘‘ gland-groups”’ secreting a flocculence of a waxy 
nature. : . 
Antennae six-jointed ; the sixth article bearing a rudimentary ‘‘ processus termi- 
nalis” or spur. 
Cornicles small, pore-like, hardly rising above the level of the body. 
Cauda scarcely constricted. 
Wings plain or pigmented. 
Rudimentary gonapophyses in viviparous females two in number (oviparous 
females in Shivaphis celti have four). 
Other characters much as in Callipterina.' 
Tuberolachnus viminalis (Fonsc.) Mordw. 
Hosts.—Salix tetrasperma ; Salix aegyptica (Bed-mushk or Scent willow) ; Salix sp. 
Synonyms.—Lachnus viminalis (Fonsc.), L. dentatus (Te Baron) and L. fuliginosus,

This is the largest Aphid of the plains, possessing characteristic facies which 
render its recognition very easy. In every respect it is identical with the insect as met 
with in Europe and America, but seems so far to be unrecorded from_Asia. The larger 
branches of Salix trees are covered over in patches of several inches in length with 
! [The genus Shivaphis, Das, is a very remarkable one, but it does not deviate so much from other 
Callipterinae as Mr. Das thought. Indeed, in my opinion, this genus torms a very interesting and 
hitherto missing link between the bulk of true Callipterinae and the somewhat aberrant genus Phylla- 
phis, Koch. 
From all true Callipterinae Shivaphis celti shows the greatest resemblance to“ Ptychodes”’ juglandis, 
Frisch (sub Péerocallis by v. d. Goot). But whilst in Pt. juglandis the aborted spur is still about half as 
long as the base of the ultimate joint, in Shivaphis celti its length is much more reduced, to about 4 
the length of the basal part of joint VI. The caudal parts and wings in both species are nearly similar. 
The cornicles, although smaller, in Shivaphis still distinctly show above the level of the body; they are 
somewhat conical, not pore-like as Mr. Das shows them to be. The presence of wax-glands in Shivaphis 
celh does not separate it from other Callipterinae, as Mr. Das thinks, since we find such glands in some 
other true representatives of this tribe, such as Euceraphis betulae, Koch, Subcallipterus alni, Fabr. (2) 
and Pterocallis tiliae, L. (9 ). 
The principal character of Shivaphis in common with Phyllaphis is the smallness of the spur ; other 
common characters, as mentioned by Mr. Das, are of little or no importance. 
I do not think that the discovery of Shivaphis celti should necessitate the creating of a new separate 
tribe next to Callipterina. The discovery of Shivaphis gives us one more very valuable contribution to 
our knowledge of the Callipterina, showing that the genus Phyllaphis does not indeed deviate very much, 
but is connected by some intermediate forms to the bulk of typical Callipterinae. P. v. d. G.].
