NO. 1124. HE VISION OF THE MELANOPLISC UDDER. 131 



e } . Body, tegmiua, aud legs almost wholly green, the hind femora not 

 banded. 



/'. Sides of the disk of the prozona with a distinct narrow yellow stripe, 

 extending to the upper margin of the eyes; passage of the disk of the pro- 

 notnm into the lateral lobes more gradual than in the alternate category; 



hind tibiae green ; antennae apically infuscated 10. herbaceua (p. 153). 



/*. Disk of prouotum and summit of head uniform in coloration, the for- 

 mer passing into the lateral lobes with a more distinct angle than in the 

 alternate category; hind tibiae blue; antennae uniform. 



11. flavescens (p. 155). 



e 2 . Body, tegniina, and legs brown or testaceous, the hind femora generally 

 banded with dark colors. 



/'. Forks of the male furcula more or less obliquely or transversely trun- 

 cate at tip and given an oppositely hooked appearance by the rounded 

 excision of the inner margin; hind femora generally distinctly banded. 

 g l . Highly variegated, the lateral lobes of pronotum conspicuously 

 marked with an unequal bright Savons stripe next the lateral carinae; 

 male cerci very feebly expanded and externally sulcate apically. 



12. pichis (p. 156). 



# 2 . Rather uniform in coloring, the lateral lobes with no bright stripe; 

 male cerci in no way expanded apically and externally tumid rather 

 than sulcate. 



h '. Lateral lobes of prozona wiffli a broad and usually distinct piceous 

 baud above; tegmina generally distinctly flecked along the middle 



line 13. fiowditchi (p. 157). 



* h '. Lateral lobes of prozona with a narrow or no distinct band above; 

 tegmina very obscurely flecked, if at all, along the middle line. 



U. favidus (p. 158). 



f 2 . Forks of the male furcula rounded symmetrically at tip, the inner 

 margin scarcely more excised than the outer, so that the forks are straight 

 and not oppositely hooked ; bands of hind femora scarcely perceptible. 



15. elonyatns (p. 160). 



d 2 . Furcula of male variously developed, rarely at all unusually broad and 

 flattened, and then either not apically emarginate on the inner side, or the 

 subgenital plate is considerably elevated apically, or both. 



e ] . Subgenital plate of male almost or quite as broad as the marginal length, 

 its apical margin generally notched; cerci broad and nearly equally broad 

 throughout (except sometimes narrowed by the oblique excision of the lower 

 side of the apical half), the basal half scarcely tapering, the whole rarely 

 more than twice aud never thrice as long as the middle breadth (except in 

 a few cases, and tbeu the apical margin of the subgenital plate is mesially 

 notched), very broadly rounded at apex. 



/'. Apical margin of subgenital plate of male not mesially notched; meso- 

 steruum of male variable. 



//'. Apical margin of subgenital plate of male but slightly elevated 

 above the lateral margins and moderately prolonged posteriorly; meso- 

 sternum of male in front of lobes flat (4. Glaucipes series). 

 /i 1 . Prozona of male longer than its posterior breadth; lateral carinae 

 more pronounced on prozona than on metazona; interval between 

 mesosternal lobes of male twice as long as broad; hind tibiae blue. 



16. ylaucipes (p. 161). 



h-. Prozona of male transverse ; lateral carinae more pronounced on 

 metazona than on prozona; interval between mesosternal lobes of 



male subquadrate ; hind tibiae red 17. kennicottii (p. 163). 



f/ 3 . Apical margin of subgenital plate of male conspicuously elevated 

 above the lateral margins and greatly prolonged posteriorly; uiesoster-
