APHIS SAMBUCI. 99 



Head and thorax black. Abdomen oval, ferruginous 

 red, with seven or more black dorsal bands and three 

 lateral spots. Nectaries and tail very small and black. 

 Legs reddish, with black femora and tarsi. Antennae 

 and eyes black. Wings very broad, with rounded tips. 

 Insertions yellow, with smoky-grey cubitus and stigma. 

 Yeining black and somewhat coarse. Post-costal 

 nervure of lower wing much curved. 



The imago of this species has some resemblance to 

 Aphis amygdaU. The larval form, however, is quite 

 dissimilar. Specimens were kindly forwarded to me 

 from Aberdeen, in September, by Prof. James Trail, 

 who found them sparingly on the capitula in the axils 

 of the ray-florets of the daisy, Bellis perennis. 



Aphis sambuoi, Linn. Plate LXX, figs. 1 — 4. 

 Fab., Schr., Kalt., Walk., Koch, Pass. 



Apterous viviparous female. 



Large. Globose, wholly dull black, with a greenish 

 shade. Abdomen domed. Cornicles long and straight. 

 Some old specimens have a tendency to show dull 

 grey bars on the abdomen, like A. rumicis. The young 

 are bright green, with large heads and small short 

 cornicles. They speedily change colour as they grow, 

 their passage into black being often eif ected in twenty- 

 four hours. Their rostra are very long and stout, 

 extending to three fourths the length of the body. 



Pupa. 



These are coloured very much like the larvae, and 

 have greyish-green wing-cases.
