The viviparous winged female. While a pupa the body and the 

 limbs are hairy : the body is bright red : the limbs are yellow ; the 

 tips of the feelers, the eyes, the tip of the mouth, the knees, the 

 feet, and the tips of the shanks are black : the feelers are hardly 

 half the length of the body. It acquires wings in the middle of 

 June, and is then red : the disc of the chest is dark gray : the ab- 

 domen is yellow, elliptical, shining, broader than the chest, covered 

 with little black dots, and having a whitish line bordered with 

 darker colour along its back ; it is paler beneath : the feelers are 

 yellow, and hardly half the length of the body ; their tips are 

 brown : the mouth is yellow with a black tip : the nectaries are 

 black, and each of them is surrounded by a red circle : the legs 

 are yellow ; the knees and the tips of the thighs are dull red ; the 

 feet and the tips of the shanks are black : the wings are colourless 

 and longer than the body ; the wing-ribs are yellow ; the brands 

 and the veins are dull red ; the rib-veins begin to widen into the 

 brands at about half the length of the wing ; the brand is long 

 and linear ; the angle near its tip is less obtuse than that of A. 

 Abietis, but more obtuse than that of A. Picece ; the fourth vein 

 is nearly straight ; the third vein is obsolete near its source ; it 

 is forked before one-third and forked again after two-thirds of its 

 length ; the angles formed by these forks are very acute; the tip 

 of the upper branch of the second fork is very near the tip of the 

 fourth vein ; the first and the second veins are almost straight ; 

 they are near each other at the base, but very far apart at the 

 tips. 



Length of the body 2 lines ; of the wings 5 lines.
