SUBFAMILY III. LOCUSTIN.E. 413 



192. MELANOPLUS BBUNEBI Scudder, 1897b, 18. Bruner's Locust. 



Size medium for the genus, the sexes subequal. Reddish-brown above, 

 greenish-yellow beneath, occiput and disk of prozona dusky; upper third of 

 prozonal lateral lobes with a fuscous or piceous patch. Tegmina pale red- 

 dish-brown, the median area with a row of vague fuscous spots, more dis- 

 tinct in female. Hind femora dull yellow, the upper and inner faces with 

 three faint oblique darker bars. Hind tibiae pale red fading to dull yel-

low, the spines black. Interocular space as wide as first antennal joint, 

 male, as frontal costa above the antennae, female. Fastigium feebly de- 

 clivent, widely not deeply sulcate, male, more shallowly so, female. 

 Frontal costa wide, strongly convex above the antennae, deeply concave 

 just below the ocellus. Pronotum short, the disk nearly flat above; pro- 

 zona but slightly longer than metazona, the latter finely and densely punc- 

 tate, its hind margin broadly obtuse-angulate. Extremity of male abdo- 

 men strongly upturned. Supra-anal plate narrowly oval, the apex obtuse, 

 margins strongly upcurved, median sulcus deep, percurrent, widening on 

 apical third. Furcula elongate, rather slender, subparallel processes reach- 

 ing beyond middle of supra-anal plate, their sides sinuous, basal thirds at- 

 tingent, apical ones well separated. Cerci as described under the series 

 heading. Subgenital plate with apex wide, much prolonged and elevated 

 the tip broadly rounded or subtruncate, with a distinct subapical depres- 

 sion which sometimes extends upward to form an apical notch. (M. alas-

Isle Royale, Mich. (HuM)cll) ; Montana and Fort McLeod, Al- 

 berta (Bniner). Known from east of the Mississippi only from 

 Nipigon and Dwight, Ontario, and Pequaming I>ay and Isle Roy- 

 ale, Mich. At Nipigon E. M. Walker (1009, 205) says it "occurs 

 in great abundance, far outnumbering all the other Melanopli to- 

 gether, being particularly abundant in a rough bushy clearing on 

 a sandy loam where it was associated with large numbers of 

 Gamnula pcllucida. The Xipigon specimens exhibit great range 

 of variation in size, color, wing-length and in the development of 

 the depression or notch below the apical margin of the subgenital 

 plate in the male. All gradations of this notch exist between in- 

 dividuals in which the apical margin is entire (typical bruneri) 

 and those in which the margin itself is as deeply or more deeply
