372 FAMILY VI. ACKIDID.E. THE LOCUSTS. 



Fox (Ms.) states that about Macon "hebardi is, next to scud- 

 deri, the most frequent of the short-winged Melanopli, occurring 

 in the undergrowth of woods, especially in low wet areas." 



Rehn's unique male type, taken in Thomas Co., Ga., Jan. 6, is 

 the only adult so far recorded. Several nymphs were found by 

 R. & H. at Albany, Ga., on August 1, in the ''heavy undergrowth 

 of the long-leaf pine forest along the Flint River." 



164. MELANOPLUS NUBILUS Rehn & Hebard, 1916, 217. 



Size small for the group. Color of decorus, the males with dark post- 

 ocular stripe ending at front margin of metazona, and dorsal surface as 

 well as sides of abdomen fuscous. Females with postocular stripe on pro- 

 zona subobsolete or interrupted and only the basal thirds of abdominal 

 segments black. Prozona one-half longer than metazona, the latter with 

 sides subparallel, surface rugose-reticulate and hind margin broadly 

 rounded. Tegmina as in attenuates. Supra-anal plate much as in deco- 

 rus and australis, but somewhat shorter, the subapical internal ridges fee- 

 bly converging and uniting to form the apex of the plate (Fig. 128, e.) 

 Furcula very slender, subparallel, finger-like projections, about one-fourth 

 the length of the supra-anal plate. Cerci very slender, the apical third fee- 

 bly widened, its dorsal portion flattened and tips subtruncate and distinctly 

 emarginate (Fig. 127, e.) Length of body, $, 15.816.8, 9, 21.225; of 

 pronotum, $, 3.74.1, 9, 4.9 5.3; of tegmina, $, 2.63.8, 9, 3.84.5; of 

 hind femora, $, 9.3 10, 9, 12.4 13.1 mm. (Fig. 129, a.) 



This form is recorded only from the type locality, Fayetteville, 

 N. Car., Sept. 9. It also appears to be very closely related to 

 (ittcniuitiis, and a large series will probably prove that attcnuotus, 

 licbardi and nn1)i1ns are but forms of a single species varying 

 slightly in color and in the structure of the male abdominal ap- 

 pendages. R. & H. (1916, 219) state that nubilus "was taken in 

 short-leaf pine woods around a mill pond at Fayetteville. The 

 males were occasional on gall-berry and other bushes and were 

 found usually two or three feet from the ground, sitting up warily 

 or jumping away, while the females were decidedly less abundant 

 and less active and by hiding often eluded pursuit." 



Series III. THE OBOVATIPEXNIS GROUP. 







This group comprises small or medium sized species, all of 

 which agree in having the general color dull brown above, 

 greenish-yellow beneath, with a shining postocular black stripe, 

 usually extending back the full length of the pronotal lateral lobes 

 and down the metapleimp ; hind tibia 3 dull greenish -yellow with 

 black spines; pronotum with sides of disk subparallel, male, 

 strongly divergent on metazona, female, median carina low but 

 distinct throughout; prozona one-half or more longer than meta-
