PTEROOALLIS JUGLANDICOLA 38 



Small, oval, pale greenish or bluisli yellow. Eyes 

 red. Body finely setose ; hairs capitate. Young spe- 

 cimens are nearly divested of all markings, but the 

 adults have two longitudinal rows of black dorsal 

 spots. Eostrum very short, reaching just beyond the 

 first cox£e. 



Pupa, 



Inch. Millimetres. 



Size of body 0'065 X 0-032 1-64 X 0-80. 



Length of antenni» 0*060 1*52. 



Considerably larger than the foregoing insect. 

 Colour yellow, green, and ferruginous. Wing-cases 

 pale bluish. Abdomen with four rows of black spots. 

 Koch states that the antennae are shorter than those 

 possessed by the apterous female. The example I 

 figure difi'ers in this respect. 



Winged viviparous female. 



Wholly bright yellow or orange colour. Thoracic 

 lobes rather orange-brown. Antenna short, tips of 

 the joints black. Rudimentary seventh joint about 

 half the length of the sixth.* Abdomen nearly trans- 

 parent, usually showing the internal trachese. Legs 

 and nectaries wholly yellow. Wings moderately long ; 

 the costa and cubitus somewhat curved inwards. All 

 the veins, the insertions, and stigmata fine yellow. 

 The anal ring is furnished with two papillae, which are 

 crenated. 



* On account of the size of the seventh anteimul joint possibly this 

 species might be ranged under Callipterus ; I leave it, JiQwever, wherQ 

 Passerini has placed it.
