APHIDES OP THE MIOCENE. 171 



3J lines. Head £; thorax ■§. Wing 2§. Abdomen 

 ljxf. Radoboj. 



This insect differs somewhat from the Aphis of 

 modern times. Heer remarks that it to a certain ex- 

 tent recalls a Lachnns. Yet the long nectaries would 

 certainly separate it from that genus. The wings are 

 remarkably long. The antennas are wanting, but the 

 insect better suggests a reference to Siphonojphora 

 longvpermis. 



Aphis (?) morlotti, Heer. Plate CXXXII, fig. 9. 



Sides of the pronotum parallel ; mesonotum dilated 

 in the midst. Size 3 J X| lines. Wing 2f . Radoboj. 



This insect must have been large for an Aphis. 

 Unfortunately no evidence can be gained as to its genus 

 from the antennas, which are wanting. Heer points 

 out that the abdomen is wanting. I would suggest 

 that the insect was a male, which in recent forms 

 usually has a very small abdomen, and, like this insect, 

 is well furnished with eyes and wings. No nectaries 

 are visible. 



Lachnus (?) pectorosus, Heer. Plate CXXXII, fig. 8. 



Prof. Heer refers two of the fossil Aphides from 

 Radoboj to the Lachninas. One of these, viz. the 

 following, is supposed to have fed on the bark of an 

 oak. 



Black ; pronotum very short. Head rounded, and 

 furnished with short 6-jointed antennas. Mesonotum 

 large, with equally dilated sides. Size 3^ X 1 J lines. 

 Length of wing 2\. The thoracic region is broad 

 and square ; the wiogs are very short, and folded 

 horizontally over the abdomeu. The legs are long, 

 with stout femora. These characters suggest a 

 Lachnus. All the Aphides here described in the
