CflERMES LARICIS. 37 



Pupa. 



Dark-grey or slate-colour. Body covered with warty 

 tubercles, which form orifices from which the silky 

 matter is spun. Head and thorax much produced 

 forward. Wing-cases placed far down in the meso- 

 thorax. Antennae relatively rather long. 



The pupae are pretty plentiful at the end of May, 

 and the imagos appear in early June up to August. 

 I have never, however, observed the winged Chermes 

 in anything like the abundance of the pupae ; but this 

 may be easily accounted for by their easy destruction 

 through rain, and also by the power of the wind to 

 remove them far from their birthplaces. Aphides have 

 no power to breast a strong wind ; their wings act 

 only as organs of suspension, and thus they have but 

 little directive force. 



Winged female. 



Inch. Millimetres. 



Expanse of wings 0*180 4"57 



Size of body 0'055 X 0'020 1*39 X 0'50 



Antennse 0*010 0'25 



Head and thorax dark-brown ; eyes red and large. 

 Antennae about equal to the width of the head, the 

 third, fourth, and fifth joints irregularly ringed and 

 imbricated ; terminal button bristly. Prothorax very 

 large and unweildy; meso- and post-thorax support- 

 ing the wings, less developed. Abdomen orange or 

 brown, much ringed, and plentifully furnished with 

 wavy silk fibres. Legs brown, and moderate in length. 

 Wings large, broad, greenish, and finely punctured. 

 Cubitus and stigma pale olive-green, tipper wings 

 with three simple unforked veins, the last of which 

 usually is the only one which springs from the cubitus. 



It may be a question whether the apparently parallel 

 course of the stigmatic vein below the cubitus is due 

 to more than the abnormal expansion of the cubitus
