78 MAINE AGRICULTURAL EXPERIMENT STATION. I916. 



The female nymph of the final instar is 4 mm. long and the 

 head I 1-2 mm. ; the abdomen narrower at base but wider than 

 in the male. 



The color observed is brown with the vertex yellow and the 

 pronotum yellowish or tinged with yellow; the wing pads 

 brown with the sternum and disc of the venter yellow. There 

 is a pair of round black spots on the vertex in the male and the 

 length is the same as for the female. The general appearance 

 is similar but the abdomen is much more slender and with 

 genital processes much more elongate. The abdomen is much 

 restricted at the base, appearing almost wasp-like and leaving 

 a wide space between its margins and tips of the wing pads. 

 The color in most specimens agreed with that of the females but 

 in one specimen was jet black above and on the base with light 

 yellow on the sternum and disc of the abdomen, otherwise 

 agreeing with the other nymphs. These were collected rather 

 sparingly on July 10th, eight nymphs and twenty adults both 

 were beaten from small bushes in the bog and all the nymphs 

 taken at this time were in the 4 mm. stage. It is quite evident 

 that this is the last instar as no forms intermediate between 

 these and the adults were found at the same time and place. 

 They approach more closely to the nymphs of maculipennis 

 than to any other species. 



Drakculacephala angulifera Walk. 



The nymphs of this species agree in color with those of D. 

 mollipes but the head is distinctly shorter, the front angle not 

 sharper than a right angle and the dark greenish stripes of the 

 dorsum are different. A pair of dark lines run from near the 

 tip of the vertex to the base of the terminal segment of the 

 abdomen. These enclose a distinctly light dorsal line and out- 

 side of the dark stripes, the upper surface is light green. The 

 frontal arcs are quite distinct and both vertex and front 

 slightly tumid. Length of the specimens noted and figured is 

 6 mm. The nymphs of this species occur during summer 

 and no indication of more than one brood has been noted.
