SUBFAMILY III. LOCUSTINJE. 433 



long-winded Mcla-noplnx present, and occurred on the coarse 

 grasses of a sea-beach and sparingly in open jack-pine barrens." 



Fox (1914, 514) says that stonci is restricted to the northern 

 part of the New Jersey Pine Barrens, having been taken only be- 

 tween Harris and White Horse (type locality) and near Atsion 

 and Stafford's Forge. Smith (1910, 184) states that it occurs "in 

 the low scrub under mixed pine and oak and on bare sand near 

 pine woods." 



In general color J\[. stonei is the darkest of our eastern species 

 of the genus, M. kcclcri and M. punctulotns ranking next in dark- 

 ness of hue. Rehn prefaced his original description as follows : 

 "A member of the packet nUi group and related to I/", packardii and 

 forcing but distinguished by the smaller size, more compressed and 

 excavated vertex and fastigium, narrower frontal costa, smaller 

 furcula, greater interval between the mesosternal lobes in both 

 sexes and in the rich and striking coloration.'' The fastigium in 

 the specimens at hand is more shallowly sulcate than those of 

 packet nli i, while the interval between the mesosternal lobes of the 

 female is but slightly wider than in that sex of packarcHi. 



Series XIV. THE KEELERI GROUP. 



Medium sized species of rather robust form and reddish- or 

 fuscous-brown hue, having the usual dark postocular stripe of the 

 genus vague or wanting ; male with prozona subquadrate and inter- 

 space between mesosternal lobes half or more as long again as broad ; 

 tegmina fully developed, reaching to or beyond tips of hind fem- 

 ora, their median area usually distinctly maculate with fuscous 

 spots; hind femora with outer, upper and inner faces bifasciate 

 with fuscous; hind tibia 1 usually red, sometimes pale blue or dull 

 greenish-yellow; extremity of male abdomen not greatly enlarged, 

 but feebly upcurved ; supra-anal plate broadly triangular, its mar- 

 gins but slightly recurved; cerci either distinctly forked or with a 

 strongly angulate submedian process on ventral margin ; sub- 

 genital plate variable in form. 



Two species and one variety of the group occur within the 

 limits of the territory covered by this work. They were included 

 by Scudder in his Coll in its Group, but since J/. coll inns Scudd. is 

 now recognized as a synonym of M. Inriilns (Dodge), the name of 

 the group is likewise changed. 



KEY TO EASTERN SPECIES OP KEELERI GROUP. 



o. Lower fork of male cerci very short, represented by an angle or me- 

 dian process (PI. IV, n) ; furcula rather slender spines, longer than 

 the last dorsal segment to which they are attached; median area of
