1GG BRITISH APHIDES. 



the absence of living specimens for comparison, no 

 safe conclusion can be come to as to identity. 

 Vide vol. ii, p. 6, Germ, and Berendt. 



Aphis (?) hirsuta, Ger. and Ber. Plate CXXXI, fig. 5. 



Body lancet-shaped, studded with hooked bristles. 

 Colour yellow or greenish. Darker beneath. 



This insect probably has more affinity with our 

 recent Siphonophora rosarum, than with Aphis picridis s 

 to which Berendt refers it. 



The amber must have been in a fluid state to have 

 permitted the preservation of the minute hairs so 

 distinctly seen in Berendt' s figure. 



See a full description, op. c, p. 6, Gerin. and 

 Berendt. 



Laohnus (?) dryoides, Germ, and Ber. Plate CXXXI, 

 figs. G and 7. 



Long oval, flatter above. Antennae less than half 

 the length of the body. First joint short and thick, 

 the second equally thick, but longer ; third somewhat 

 shorter than the second and drawn out thinner ; the 

 fourth smallest of all ; the fifth and sixth as long as 

 the third ; and the seventh appearing as a nail-like pro- 

 cess. The rostrum is very long, and projects about 

 one third beyond the tail. It is 4-jointcd and shows 

 an acute and narrow labrum. 



Berendt points out the resemblance this insect 

 shows to " le Puceron du chene " of Reaumur, and to 

 Lachnus queroHs of Burmeister. The general colour of 

 the amber insect is yellowish-brown. Vide Germ, and 

 Berendt. j op. c, vol. ii, p. 4. 



The articulation of the antenna is different from 

 that in recent Lachninaa, and the rostrum also differs 

 both as to length and articulate proportion. No necta- 

 ries are marked in the anflber specimen ; though the
