168 UKITISH APHIDES. 



Aphis (?) tkansparens, Germ, and Ber. Plate CXXXI, 



fig. 10. 



" Supra fusca, subtus pallida, pedibus fuscis, alis albis, nitidissimis, 

 vena costali fusca." — Berendt. 



Perhaps a Laclmus ; but as the antennas are imper- 

 fect and the wings cover the hinder part of the body, 

 it is difficult to determine. The resemblance both in 

 size and appearance to Aphis pmi perhaps justifies its 

 reference to the genus Aphis. Berendt' s diagnosis 

 in substance is as follows : — Head rounded in front, 

 broader than the thorax, black above, pale below ; 

 rostrum rather shorter than the body. Back (thorax ?) 

 black, and divided into four lobes by a depression 

 forming a St.-Andrew's cross. Abdomen short and 

 broad. Lower parts of the sides seem to be raised 

 into tubercles, but this may be due to the nodular form 

 of the amber. Only one antenna is perfect. It is curved, 

 with two small rounded basal joints, and a long clavate 

 third joint, followed by two vasiform equal articula- 

 lations, which together do not equal the third in length. 

 The fourth joint is awl-shaped ; and perhaps a fifth 

 and sixth joint once existed. Wings unusually large; 

 round at the points, with a broad vein running parallel 

 to the outer edge (cubitus), from which these oblique 

 veins proceeded ; one of these has the usual furcation 

 of Aphis. The hinder wings are small. The veins 

 are not easily traceable. 



The colours appears to be pale, transparent, and 

 shining. 



The legs are long, slender, and brown; tarsi 2- 

 jointed, with two claws (perhaps intended by the term 

 Zweilappig). 



As this is the only winged specimen figured by 

 Berendt in the Prussian amber, I have given above his 

 diagnosis pretty completely.
