NO. 1124. REVISION OF THE MELANOPLISCUDDEB. 221 



The prozona is quadrate or subquadrate in the male, but in some 

 brachypterous forms longitudinal. The interspace between the meso- 

 sternal lobes in the same sex is always longer than broad and sometimes 

 more than twice as long as broad. The tegmina are either fully devel 

 oped or slightly abbreviate so as not to surpass the hind femora, or 

 else they are shorter than the pronotum, and then apically rounded or 

 very bluntly subacuminate, generally slightly maculate. The hind 

 tibiae vary in color, and have from nine to thirteen spines in the outer 

 series. 



The supraanal plate of the male is generally as in the femur-rubrum 

 series, but the apical third or more is frequently depressed. The fur- 

 cula is very variable, being either as in the devastator series, but gen- 

 erally rather shorter, or reduced to distant slight dentations or to 

 rounded partially projecting lobes. The cerci are generally symmetric- 

 ally rounded at tip and otherwise as in the femur-rubrum series, or 

 with very slight difference in breadth basally and apically, usually 

 rather short, and in one instance bent abruptly inward at less than a 

 right angle. The subgenital plate is usually broad throughout, the 

 apical margin well rounded and slightly elevated but not emarginate? 

 but sometimes it is rather narrow throughout and not apically elevated. 



The species of this group, seven in number, are divided unequally 

 between macropterous and brachypterous forms, one species being di- 

 morphic, four others brachypterous, and two macropterous. They 

 occur almost wholly in the great interior region between the Mississippi 

 River and the Eocky Mountains, and extend from Alberta and Assini- 

 boia to central Mexico. No species are known from the Pacific Coast 

 and only one east of the Mississippi, in Georgia and North Carolina. 



46. MELANOPLUS REFLEXUS, new species. 

 (Plate XV, fig. 1. ) 



Dull ferruginous brown, lutesceut below and on abdomen. Head 

 luteo- testaceous, more or less marmorate with light fuscous, fusco-ferrug- 

 inous above, with a broad postocular piceous patch ; vertex very gently 

 tumid, not elevated above the pronotum, the interspace between the 

 eyes rather broad, much broader than, in the female twice as broad as, 

 the first antennal joint; fasti gium rather rapidly declivent, very feebly 

 and broadly sulcate in the male, nearly plane in the female; frontal costa 

 broad, failing to reach the clypeus, slightly contracted above, at least 

 in the male, almost (female) or fully (male) as broad as the interspace 

 between the eyes, feebly and narrowly sulcate at and below the ocel- 

 lus, punctate throughout but nowhere seriately ; eyes moderately large, 

 not prominent, a little longer than the infraocular portion of the geuae; 

 antennae ferruginous, in the female less than two-thirds as long as the 

 hind femora. Pronotum short, subequal, very faintly and uniformly 

 enlarging posteriorly, rather full than contracted in the middle, very
