Life-mstory.—During the rest of the year the life-history is still unknown. There 
is only one host; cultivated saffron (Carthamus unctorius) is not known to be 
attacked and is not grown in Lahore. 
The systematic position of this new Aphid is quite interesting. I have very 
hesitatingly placed it along with the Peganum-species in the genus Brachyunguts. 
The spur being shorter than the base, the cornicles smaller than the cauda, and the 
presence of lateral tubercles are features in common with that genus. But important 
differences, some of them given below, mark it off clearly from Brachyunguis :— 
(I) The cornicles are black, conical and broad-based, not hyaline or cylin- 
drical. 
(2) The spur of the 6th antennal article is not so small, sometimes it is almost 
subequal with the base. 
(3) The cauda is not quite double the length of the cornicles but much less. 
(4) Specially noteworthy is the presence of secondary sensoria on articles III 
and IV even in the case of the apterous viviparous female. 
Of all the genera catalogued from Europe and America that combine A phis-like 
characters (Apis, Linn., Mordw., van der Goot) with the cornicles smaller in length 
than the cauda, this species approaches nearest to Brachyunguis, gen. nov It, how- 
ever, considerably diverges from the type. But for fear of muitiplying and erecting 
new genera for single species I have tentatively allowed it to stand in this group. 
Eichochaitophorus himalayensis, sp. nov. | 
Host.—Several species of Salix that grow along the banks of canals, streams and 
rivers. 
A small insect, chiefly sitting along the midrib of the leaves, or encrusting the 
tender shoots just above the stipules. Light greenish to yellowish in colour ; two 
crescentic bands around the bases of the cornicles on the dorsum, meeting two elongated 
spots on the first abdominal segment ; another blotch on the thorax ; all of a dark 
green colour. 
Cornicles truncate, with a network of lines on the surface ; cauda constricted , 
knob-like; anal plate notched and a few large sensoria on the third joint of the winged 
female are distinctive characters. Plenty of sooty fungus blackens the lower leaves 
of the host-plant and ants both small and large are always in attendance. 
DESCRIPTION. 
A pterous viviparous female.—Body oval to ovate, covered with long bristly hairs, 
directed backwards. 
| [Brachyunguis carthami, Das, is indeed somewhat different from the other species of the genus, 
especially in the somewhat conical form of the cornicles, in which respect it shows some relation to the: 
genus Longiunguis, v. d. G. The different other characters of this species however, such as the short- 
ness of the “‘unguis”’ (spur) and the very flattish, almost rudimentary lateral tubercles, make it advis- 
able that Br. carthami should not be separated from its original genus. 
Secondary sensoriae on the antennal joints of the apterous female, as present in this species, are 
likewise found, as far as known, in Aphis jacobeae, Schrk. and Aphis senecionis, Williams. P. v. d. G.].
