No. I. ] Miscellaneous Notes. 41 



that they infest apricot, ahitioiid, 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 Ideed profusely. 



The wingless foi-ras were noticed from March onwiirds, and in the 

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

 liave 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 

 hitter part of November, a fortniglit's rainy weather in November not 

 :ipi)earing 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. Cleghorn as causing the 

 bleeding of poplar trees in that region. Sjjeciuiens were sent to Mr. Gr, B. 

 Buckton, who has determined the insect as a new species of Lacknus 

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

 kindly furnished upon the insect is as follows: — • 



" The specimens embraced the tliree different; stages of larv«, pupae, 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 their upper and lower 

 wings, posset.s short six-jointed anteunse 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 i«c/^w?'«(» 



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

 tion, viz. Lachnus viviinalis, feeds on the willow bark. Hitherto the plum, the 

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

 insects of the genus Zac/«« 1(5. 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 I name 

 this Quetta insect Lachnus fuliginosus, nov. sp. 



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

 small, vertical edge round. Eyes, small. Thorax separated from the abdomen b}^ 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. 

 Nectaries 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 16xO'U9 

 inch = 4-0 X 22 millimetres. Antenna 005 inch = 1-27 mil. 



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

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

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

 the larval sttige. The wing-cases aie about equal to one-third the length of the b(;dy. 



" Lmago. — Vivipnrous female. Head small ; vertex rounded, and finely pilose. 

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

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

 of all. Ti)e 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.
