98 ~ Harrison: Aleuropteryx lutea (Wallengren). 
Enderlein’s Helicoconis and describe the insect under Low's 
name of Aleuropteryx lutea. 
Aleuropteryx lutea Wallengren. 
Wing expanse 5°7 to 6 mm. 
Head slightly narrower than the thorax; whole body 
covered with a whitish secretion slightly dingier than that of 
Conwentzia psociformis Curt. Antenne 24-27 jointed, of a 
yellowish colour, somewhat more intense near the joints. Palpi 
dull grey. Legs similarly coloured to the antennae; tibie 
thinnish, sub-cylindrical. 
Forewings radial ramus* simple ; media dividing into three 
branches ; radial ramus connected with media by two cross 
nervules, one near the base of the radial ramus and the other 
near the base of the second fork of the media. 
Hindwings radial ramus arising near the base of the radius 
and like the media breaking into two forks. 
Taken at Wolsingham, co. Durham, at about 1,000 feet 
July, 1915. 
There is some mystery attached to the specific name 
‘lutea’ given to this insect. Wallengren described the insect 
as covered with a yellowish grey mealiness from which he 
evidently obtained the ‘ /utea,’ but, very early (1880), McLach- 
lan pointed out that the name was not justified, suggesting 
that Wallengren had before him old specimens, and this was 
probably the case for the species is not yellowish. As a matter 
of fact, O. M. Reuter (Fért. och Besk. dfuer Finlands Neurop- 
terer, Acta Societatis pro Fauna et Flora Fennica IX. No. 8), 
who probably has had through his hands more specimens of 
this insect than anyone else, describes the insect thus: ‘ Hela 
kroppen tackt af ett hvitt mjéligt sekret,’ practically the same 
formula as he uses in describing Semidalis aleurodiformis Steph., 
and my insect exactly agrees with this description, as evidently 
did McLachlan’s. From this we must conclude that Wallen- 
gren’s insects were old as McLachlan surmised.

We much regret to record the death of Sir Clements Markham, K.C.B,, 
the well-known geographer, which occurred as we went to press with our 
last number. He was in his 86th year. Sir Clements was engaged under 
Captain Austin in the Franklin Search Expedition of 1850-51. He visited 
Peru to inquire into the remains of the old Inca period, and arranged for 
the transmission of valuable Cinchona plants from South America to 
India. He was for twenty-five years the secretary. of the Royal Geo- 
graphical Society, and then for twelve years its President, and was largely 
responsible for the success of the National Antarctic Expedition. He was 
a Fellow of the Royal Society. Sir Clements died as a result of burns 
received while reading in bed with the aid of candle light.
