that they infest apricot, ahiiond, and peach trees, swarming- in patches 

 from six inches to a foot in length on the undersides of the branches, 

 especially of the apricot, and causing the trees to bleed profusely. 



The wingless forms were noticed from March onwards, and in the 

 early summer they were so numerous that it was found worth wliile to 

 have them rubbed off daily by hand. Winged individuals were found for 

 a short time in October, eggs and young appearing on a few trees in the 

 latter part of November, a fortnight's rainy weatlier in November not 

 appearing to affect them This insect has not been previously recorded 

 as attacking fruit-trees in Baluchistan, though it may not improbably 

 be the same as what has been noticed by Mr. CTeghorn as causing the 

 bleeding" of poplar trees in that region. Specimens were sent to Mr. Gr. B. 

 Buckton, v^ho has determined tne insect as a new species of Lachniis 

 which he describes as Lachnns fnUginoms. The report which he has 

 kindly furnished upon the insect is as follows: — 



"The specimens embraced the three different stao^es of larvae, pupse, and a few 

 winged examples of viviparous females. These insects clearly belong to the Lach- 

 nince, or Aphides, which show the full number of nervures in tiieir upper and lower 

 wings, possciss short six-jointed antennse and thick mammilliform nectaries or corni- 

 cles. 



" The Quetta insects do not exactly agree with any described species of Lachnus with 



which I am acquainted I may mention that, as a rule, the European iac>%?«/«de 



feed upon conifers, but not exclusively, for an Aphis, very like the one under examina- 

 tion, viz. Lachnus viininalis, feeds on the wilJow bark. Hitherto the plum, the 

 peach, and the apple tree have not been recorded as liable to the attacks of these 

 insects of i\iQ genus Lachnus. Several important differences, as will appear by the 

 following diagnoses, lead me to suppose this to be a new species, notwithstanding 

 certain resemblances to the willow Lachnus before mentioned. Provisionally 1 name 

 this Quetta insect Lachnus fuliginosiis, nov. sp. 



" Larva. — Variable in shape according to age ; either long-oval or globose. Head 

 small, vertical edge round. Byes, small. ^Thorax separated from the abdomen by a 

 slight stricture. Antenna rather short, stout, and hirsute, six-jointed, the nail being 

 counted as one. Abdomen rugose, and studded with black shining tubercles. 

 Neclaries stout and mammilliform. Apex of abdomen round, hirsute, and without a 

 visible Cauda. Legs long, yellow, with black points to the femora and tibiae Tarsi 

 black and two-jointed. Rostrum one-third the length of the body. Length 16X0"(J9 

 inch =: 4'0 X 2'2 millimetres. Antenna 005 inch = 1"27 mil. 



" Pupa. — More linear in form, but much of the same cohiur as the larva. On the 

 somite preceding that on which the cornicles are developed, a curious horn-like process 

 rises, out of the dorsum. In Lachnus viminalis this horn appears to be restricted to 

 the larval stnge. The wing-cases aie about equal to one-third the length of the bcdy. 



" Imago. — Viviparous female. Head small ; vertex rounded, and finelj^ pilose. 

 Antennae black, and fringed with hair ; about half the length of the body ; with two 

 stout basal joints ; the first of wliich is rather the longest ; the third joint the longest 

 of all. The fourth and fifth about equal length ; the fourth sometimes shows a con- 

 striction or a tendency to subdivide. The nail-like process on the sixth is sometimes 

 so large as to suggest the antennae to consist of seven joints instead of the normal 

 number of six. Eyes moderately large, and apparently without any supplemental eyelet.
