143. EOTETTIX PUSILLTJS Morse, 1904a, 7. Little Eastern Locust. 



Short, rather robust. Fale yellowish-green, the dorsal surface and 

 tegmina brownish; upper third of prozonal lateral lobes, upper sides of 

 hind knees, tips of hind tibia?, tibial spines, and tarsal claws, piceous- 

 black; the entire body in life suffused with a metallic velvety lustre which 

 mostly disappears in dried specimens. Head wider than pronotum; fron- 

 tal costa above the antennae four-fifths the width of interocular area, ab- 

 ruptly narrowed below the ocellus to two-thirds of its width above. Eyes 

 very prominent. Pronotum relatively shorter than in the other species, 

 its disk feebly tectiform; median carina sharp; prozona one-third longer 

 than metazona, the latter finely rugose. Tegmina as described in key 

 Tip of male abdomen upcurved; supra-anal plate triangular, as broad at 

 base as long, the median basal groove very short; furcula as in palustris; 

 cerci slightly shorter than the supra-anal plate, awl-shaped, their tips 

 acute. Length of body, $, 1012, $, 15.520; of antenna?, $ and $,

Denmark, S. Car., Aug. 15 (Morse). This, the pygmy of the 

 genus, and one of the smallest of Acridians, has been taken in 

 Florida only at Live Oak, Aug. 126, by R. & H. It was described 

 from Waycross, Ga., and Denmark, S. Car., and is known also 

 from Fayetteville, N. Car., and several points in South Carolina 

 and Georgia. It occurs principally on w r ire-grass in open pine and 

 oak woods and seems to be scarce wherever found. The nymphs 

 are said by R. & H. to be "blackish, overlaid with mars orange, 

 the latter color forming a pale postocnlar stripe and strongly 

 indicated over the face and the distal portion of the caudal 

 femora." 



IV. HESPEROTETTIX Scudder, ISTOa, 262. (Gr., "western" -)- 



"grasshopper.") 



Small to median locusts, the sexes not differing greatly in size. 

 They have the sides nearly parallel ; head small ; vertex opposite 

 middle of eyes very narrow, often but little wider than second 

 joint of antennse; face but little oblique, frontal costa usually 

 narrow, sulcate throughout, punctate; antennne of female a little 

 shorter than or equalling head and pronotum together, of male a 

 fourth longer, the joints slightly flattened ; eyes rather small, 

 longer than the cheek below them; pronotum longer than in allied 

 genera except Paroxya, the prozona usually half as long again as 

 metazona, the sides of disk broadly sloping; median carina low, 

 not cut by the first and second sulci ; hind margin very obtusely 

 angulate or broadly rounded ; lateral lobes of pronoturn with front 

 and hind margins nearly straight, oblique, lower margin with its
