This insect has been collected only from Letsonia scandens in the Botanical 
Garden during the month of October, 1913. Soon after this it disappeared and 
was never found afterwards even during March and April. Letsonia is neither a 
common nor perhaps an indigenous plant in Lahore. For the sake of its beautiful 
silvery leaves it is cultivated in gardens as an ornamental creeper. 
The Aphid infests the tender young branches and the inflorescences of the 
plants. 
Nothing is known about its further history and probably some alternate host 
may be found later. 
The species is named after the host-plant and evidently belongs to the new genus 
Brachyunguns. 
Brachyunguis (?) carthami, sp. nov. 
Host.—‘‘ Wild safflower ’’ Carthamus oxycarpt. 
Distinguishing characters.—Body oblong ; ashy-gray on account of the thick mealy 
coat; two large rectangular blotches internal to the cornicles and rows of other black 
spots on either side with one in the middle; cornicles black, smaller than cauda; lateral 
tubercles large and antennae short with sensoria even on the joints of the apterous 
viviparous female; it appears in the hot months of May and June. 
MORPHOLOGICAL DESCRIPTION. 
Apterous viviparous female.—Body oblong to ovate, rather depressed, thickest in 
the cornicular region ; showing distinct carinae in most specimens. 
Colour ashy-gray or whitish, in life almost cryptic on its host; but this is due to 
a very thick layer of pulverescence which conceals the real reddish-brown colour of 
the insect. 
The pattern on the body becomes visible on removal of the meal with a drop of 
alcohol. It consists of two prominent irregularly-rectangular spots, internal to and 
slightly in front of the cornicles. A median row of dots extends from behind the head 
right up to the cauda; on the thoracic segments the spots are largest and faintest on 
the anterior abdominal segments; a double row is noticeable near the lateral grooves 
and still another is formed by the black and conspicuous lateral tubercles. The skin 
bears a mosaic of anastomosing lines. 
Head rounded in front, black, about as long as broad, 
Eyes black.
