170 BBIUSH APHIDES. 



insect might better be referred to Siphonophora, but 

 I do not wish to speak with confidence. The last 

 abdominal rings are wanting, but in Heer's figure 

 they have been dotted in of their probable size. He 

 Bays the stigma (Fliigelmaal) is very long and thin, 

 as we see in the Lachnus group. This specimen still 

 has some local colour attached to it, for the abdomen 

 is noted as darkish coloured, rather paler than on the 

 breast, and its tail end is yellowish. Cornicles black. 

 For a more complete description of this insect vide

Lachnus (?) bonneti, Heer. Plate CXXXII, fig. 3. 



This insect lived on a species of Pinus, and according 

 to Heer was nearly allied to the recent Lachnus pini 

 which affects Pinus sylvestris. 



Black. Abdomen pallid; wings moderately large. 

 Size of abdomen 1J. Thorax -J. Wing 1| lines. 



Heer marks this as a Lachnus, but the length of 

 the nectaries excludes it from this genus. The 

 antennse have not been preserved ; the wing-veining 

 is very obscure, and no stigma is distinguishable. 

 Possibly the insect would better recall the modern 

 Aphis abietis. 



Aphis (?) delicatula, Hie< r. Plate CXXXII, fig. 6. 



The remains of this insect are very fragmentary; 

 and beyond the fact of its being an Aphis there arc 

 few characters to be relied on. The wing-veining 

 appears to be a little abnormal.
