with the beginning of what is unquestional)!}' in the adult a very 

 decided lobe, the distal margin of which in the nymphal condition 

 is nearly rectangulate, the whole being considerably elevated dorsad 

 of the shaft of the cercus. The distal portion of the cercus is little 

 curved, robust, slightly depressed, the apex acute. Subgenital plate 

 moderately produced, subequal in width, the distal margin deeply 

 rotundato-emarginate, the lateral angles acute, slightly recurved 

 toward the median line. 



Parahjpic Series. — We have before us two paratypic adult females, 

 one of which is measured below.

Color NotesM — General shade ranging from old gold to oil green, 

 on the pronotum paling (in the old-gold individual) to light viridine 

 green. A pair of narrow lines of blackish 'are more or less distinctly 

 indicated, extending from the dorsal margin of the eye caudad over 

 the sides of occiput and along the lateral angles of the pronotal disk, 

 margined laterad by a band of empire yellow of varying width and 

 <lefinition. Eyes argus brown, blotched with blackish; antennae 

 with the two proximal joints ranging from claret brown to burnt 

 sienna, remaining joints blackish with narrow dull apricot yellow 

 distal annuli; occiput more or less washed with very dull weak 

 maroon. Dorsum of pronotum with cephalic half of disk very 

 weakly washed with morocco red, a medio-longitudinal line of 



'0 In both of these females the abdomen has been bent ventro-cephalad and 

 in consequence the length given above is not the real length of the insect, but 

 only the shortest distance between the point of the fastigium and the base of the 

 ovipositor. It is not possible to get a true measurement of length from the 

 present material. 



'1 In the present notes only the two well-preserved adults have been used, a 

 few notes on the nymphs being placed at the end.
