tlir iiieso8teriial lo]>es. The tetriiiina are frequently abbreviate or even 

 M anting; when fully «lev<'l()|MMl, they t;ii>er ^jently alinoHt tlirou;rli(mt 

 and are rather remotely retieulate at least in their apieal half, the cells 

 oC tin- jK)8tra(lial area wholly or partially biscriate in arrnn^enieiit on 

 either side of an intorealary vein; the win^^s are almost always elear 

 and uniform, never detinitidy i)ictured, the veins never sealariform, the 

 ill eolae (|uadrate or lon«(er than bnnid. All the tarsi are furnished with 

 ail aroliiiin, the front legs are less distantly separated than the hind 

 p;iir, the fore tarsi are of moderate lentfth,the tirst joint short or rather 

 sliort: tiie hind femora are distinctly iiierassute basally, ;i:enerally sur- 

 piiss the abdomen, the upper face fjenerally smooth, the dorsal carina 

 eiitin', unarmed, not profoundly excised befoie the jjeniculation; the 

 bind tibiae have smooth lateral marfflns, the spines of the outer and 

 inner <«Mie8 are equal or subequal in length, those of the outer series 

 typically nine' or more in number, rarely exceeding fourteen, ])laced at 

 subequal distances apart and lacking an apical spine next the calcaria; 

 the hind tibiae have the lirst Joint not compressed, equal to or slightly 

 longer than the third, the second much shorter, generally a half shorter, 

 than the tirst as seen from above. The second dorsal segment of the 

 abdomen is neither granulate nor dentate at the anterior angles, the 

 extremity of the abdomen in the male generally more or less clavate 

 and recurved, the supraanal i)late not tuberculate, with a basal median 

 sulcus, a furcula usually present, the cerci very variable, rarely longer 

 than the supraanal plate, straight or gently curved, never abruptly 

 recurved basally, generally compressed at least in part, often laminate^ 

 but with no indireeted median spine. 



The foundation for our present knowledge of the structural features 

 of the Melanopli was laid by StiU ^ and enlarged in his Systema 

 Acrideodeoruin (1S78) and his Observations Orthopterologiques, II£ 

 (1878). In its present form the groui) was first detined and named by 

 Brunner von Wattenwyl,^ who applied to it the terra Tezotettiges. 

 I have here limited it strictly in the same manner, but it will appear 

 that it contains a very much larger number ot generic types than were 

 credited to it by Brunner and a vast multitude of species. I shall 

 moreover show below, when treating the genus Podisma,* that the gen- 

 eric term Pezotettix, from which Brunner derived the name of the 

 group, has been misapplied of recent years, and should be referred to 

 the group called Platyphymata in Brunner's Bevision. I have accord- 

 ingly here named the present group Melanopli after its predominant 

 genus }felanoplus, the species of which far outnumber all the others com- 

 , bined. Giglio Tos in recent papers has described several new genera and 



I ' By exception, in one sex or on one side of the body, there may be only eight.
