324 Mr. Buckton's notes on the occurrence in 



Winged viviparous female. — Expanse, 0-220 inch ; body, 

 0-080 X 0-030 inch. General colour lemon-yellow. Head and 

 antennae black, eyes red, rostrum reaching to the third coxae, thorax 

 with a broad interrupted discoidal brown or black spot. A similar 

 square spot occm-s on the dorsum, between the cornicles, with two 

 or more luteous dashes. There are also four carinal spots. Knees 

 and tarsi dark brown. Cauda absent. Wings hyaline, with the 

 usual twice-forked cubital vein. Insertions j^ellow, as also is the 

 stigma. 



Found on the stalks of the samphire, CrWimum mari- 

 tinium, growing on the rocks at Kingsbridge, situated at 

 the head of the Salcombe Estuary, Devonshire. Speci- 

 mens were kindly forwarded to me in July by G. C. 

 Bignell, Esq. 



The aphis which most nearly agrees with this insect 

 perhaps is Aphis Angelicce of Koch. But, though his 

 figure fairly answers to my drawing, the different food 

 and the peculiar habitat on the sea-shore, amongst 

 other considerations, preclude the identity of these two 

 insects. 



Lachnus pini, Linn. 



I was unable, from the want of examples, to describe 

 and figure the winged viviparous female of this species 

 in the ' Monograph of British Aphides.' The apterous 

 female is there noticed on page 50, vol. iii., and a 

 drawing occurs on plate 97 of the same volume. Through 

 the kindness of Mr. Bignell I can now describe the 

 winged form, which is relatively much smaller than the 

 apterous. The insects were taken on the spruce fir late 

 in September, and near Stonehouse, Devon. 



Winged viviparous female. — Expanse, 0-400 inch; size of body, 

 0.100 X 0-040 inch. General colour ochreous-yellow. Head black, 

 neck-ring ochreous. Thoracic lobes dark brown. Abdomen corru- 

 gated and marked with a double row of dark dorsal spots. Cornicles 

 papilliform and brown. Legs yellow, with brown femoral, tibial, 

 and tarsal joints. Antennae black. Wings with a yellowish 

 membrane, ochreous insertions, and a broad brown stigma. 

 Venation very fine, but the first cubital vein is coarser than the 

 rest. The body is covered with a fine yellow coat of hair. The 

 pupae are also small, yellow, finely spotted, and furnished with 

 dark brown wing-cases.
