h'. Prozona ordinarily with a broad median dark 



stripe, made mor nspicuous by the much lighter 



colors "ii either side, or else light brownish tes- 

 taceous; antennae of male little more than three 

 fourths as long as hind femora; hind tibia blue 



or re d packardii. 



h~. Prozona with uniform dingy coloring on disk; 

 antennae of male almost as long as hind femora; 



hind tibia red fcedus. 



g-. Median carina of pronotum tolerahly distinct on the 

 prozona, at least anteriorly, distinct and moderately high 

 on the me.azona; extremity of male cerci deeply sulcate 

 exteriorly or else tumid; forks of furcula parallel or only 



slightly divergent conspersus. 



f-. Interval between the mesosternal lobes of male subquadrate. 



rtintpactllS. 



d 2 . Cerci of male ap'ically bifurcate, or with an inferior submedian process 

 or abrupt angulation, or else expanded so as to be distinctly, generally 

 much, broader apically than at extreme base; furcula wanting or 

 minute. 



e 1 . Size small or medium; supra-anal plate of male pretty regularly 



triangular, with straight or feebly convex lateral margins: furcula 



usually distinctly developed; prosternal spine usually short. 



V. Furcula of male consisting of slender spines, longer than the 



last dorsal segment; base of lateral margins of subgenital 



plate incurved minor. 



f-. Furcula of male consisting of brief triangular lobes: base 



of lateral margins of subgenital plate incurred hiridus. 



e-. Size large; supra-anal plate of male of variable shape: furcula 

 either absent or very minutely developed: prosternal spine usually 

 long. 

 P. Furcula of male entirely absent or present only as a minute 



point or bead; hind tibia usually yellow differentialis. 



f-. Furcula of male distinctly present, though always very small, 

 angulate, the angle rarely produced; hind tibia never entirely 

 yellow birittattis. 



Melanoplus marculentus Brunner. 



Of this genus we have no representative in the collection now, but it 

 has been reported from Kansas by Hunter and Sutton, in Psyche, July, 

 1900. The following notes are taken from their report: "This specimen 

 of marculentus manifests a trait liable to appear in short-winged varie- 

 ties. It agrees with Scudder's description, with the exception of the 

 darker coloring of the upper portion of the head and pronotum and the 

 greater length of the subgenital plate, but instead of the normal abbre- 

 viate wing the insect has well-developed tegmina and wings. The teg- 

 mina extend clearly beyond the end of the abdomen and are remarkably 

 broad for one of this genus. Width of tegmina, 6 mm.; length, 11 mm. 

 (tips were frayed) ; basal half testaceous, two or three testaceous spots 

 on the discoidal area. Wings hyaline, veins and cross veins fuscous in 

 distal portion, glaucous basally." 



Locality. Russell county. 



Melanoplus lakinus Scudd. 

 Antennae a little more (male) or a little less (female) than two-thirds 

 the length of the hind femora. Frontal costa variably sulcate. Median 

 carina more distinct on metazona than on prozona. Prozona of female
