forming somewhat interrupted longitudinal lines, and with 

 three similarly coloured spots on each lateral margin ; 

 a few scattered black hairs. Mesothorax with two blackish- 

 brown dots in the middle above. 



Ahdomen often with two indistinct lateral rows of 

 blackish spots ; clothed sparingly with black hairs. 



Legs green, with blackish pubescence ; tarsi brownish ; 

 ungues dilated at the base internally, the apical portion 

 long and strongly curved. 



Wings rather short, sub-acute ; a black dot at the ex- 

 treme base of the costa. In the anterior wings the longi- 

 tudinal veins are green ; the gradate veinlets black ; all 

 the other transverse veinlets black at each end and green 

 in the middle ; pterostignia elongate, green. In the pos- 

 terior ivings the costal veinlets are wholly black ; neura- 

 tion otherwise coloured as in the anterior. 



After death changes to yellow. 



Length of body 4 lines ; expanse of wings 13-16 lines. 



Tolerably common in summer in woods.

Almost entirely similar to the last ; but the ventral 

 surface of the abdomen, excepting the last segment, is 

 black with pale transverse sutures ; the costal veinlets of 

 the anterior wings appear to be pale only at their junction 

 with the costa. 



Occurs rather frequently in woods in summer, often in 

 company with G. aspersa, and may be instantly recog- 

 nized by the black underside of the abdomen. Though 

 inclined to consider it distinct from aspersa, I think it 

 very desirable that its specific right should be proved 

 by breeding from the larva.
