'no. 1124. REVISION OF THE MELANOPLISCUDDER. 159 



low, broad, subequal, the sides moderately narrow but low (male) or 

 scarcely sulcate (female); frontal costa broad, equal, plane (male) or 

 tumid (female) above, at and below the ocellus broadly and rather 

 deeply sulcate; eyes pretty large but not very prominent. Prouotum 

 with the prozona equal, the metazona expanding and punctato-rugulose; 

 median cariua slight but distinct on the metazoua, obsolete or subobso- 

 lete on the prozona; lateral carinae subobsolete; transverse sulci of 

 prozona slight but distinct, continuous. Tegmiua extending a very 

 little way beyond the abdomen, surpassing the hind femora. Supraanal 

 plate regularly clypeate, about as broad as long; plates of the furcula 

 shaped much as in M. bowditchi, but thickened at the tip, as long as 

 the cerci or nearly two-thirds as long as the supraanal plate; the cerci 

 have a triangular base and a long, straight, slender, bluntly terminated, 

 equal finger extending backward and upward and inclined inward, 

 starting from the lower posterior portion of the base; it is as long as 

 the terminal joint of the hind tarsi; subgenital plate scoop-shaped, 

 well rounded as viewed from above, the tip scarcely produced, entire. 



The general color is greenish yellow, sometimes a little iufuscated 

 above, the head frequently mottled with fuscous; antennae uniform 

 yellowish; the usual stripe behind the eye over the upper portion of the 

 lateral lobes of the pronotum is generally reduced to a very narrow 

 dusky stripe next or on the lateral carinae, diminishing in breadth pos- 

 teriorly; or if it is broader, it sometimes invades the disk rather than 

 the lateral lobes; the disk has a median dusky line and the summit of 

 the head a dusky basal triangle. The tegmina partake of the general 

 lively tone to a less extent, and the paler median stripe, distinct only 

 at base, is seldom flecked intermittently with fuscous; hind femera yel- 

 low, the upper half of the outer face dusky, and two oblique dusky 

 patches often occur above; hind tibiae glaucous, the spines white or 

 glaucous, black tipped, ten to eleven in number in the outer series. 



Length of body, male, 20.5 mm., female, 22 mm.; antennae, male, 

 13 mm., female, 9.75 mm.; tegmina, male, 20.5 mm., female, 22 mm.; 

 hind femora, male, 14 mm., female, 15 mm.
