60 BRITISH APHIDES. 



Globose, dull black to the naked eye, but deep 

 brown under a lens ; somewhat fuscous in the neigh- 

 bourhood of the head and tail. Eyes and antennae 

 black. Cornicles black as to three parts of their 

 length, and rising from two conspicuous orange-yellow 

 spots situated at the base of the dorsum. Legs black, 

 except as to the upper halves of the tibial joints, which 

 are yellow. Tail very obtuse and inconspicuous. 



Winged mviparous female. 



Head, eyes, antennae, and entire thorax dull black. 

 Abdomen green, with three dark spots on each side. 

 Legs pale ochreous, with black femora and tibial points. 

 Cornicles dark green. Cauda small and green. 

 Rostrum short, reaching to the second coxge. Under 

 side of the belly green. Wings long. Veins somewhat 

 liable to variation. Insertion cubital and other veins 

 pale brown. Stigmata rather darker brown. 



At least three species of Aphis feed on the pear, and 

 the specific names given to them by authors are very 

 confusing. 



Koch describes an Aphis pyri, which feeds on Pyrits 

 pyraster, but it does not appear to be the insect under 

 the above notice ; and it is not Aphis pyri of Boyer de 

 Fonscolombe. On account of the rusty blotches on 

 the dorsum, I give to my insect the trivial name, 

 lentiginis. 



The figures on the accompanying plate were drawn 

 from specimens captured on the leaves of the garden- 

 pear in early June by my friend Mr. Borrer, of 

 Cowfold, Sussex, whose zoological " proclivities " are 

 well known.
