Localities. This species has been taken in all parts of the state, 

 and at times occurs in great numbers, thus causing considerable damage 

 to all kinds of vegetation, and even trees. M. bivittatus does not re- 

 strict itself to cultivated fields only, but may be found in prairies, 

 meadows and along the roadside; in fact, most anywhere where vegeta- 

 tion occurs. They will defoliate such trees as apple, peach, osage 

 orange, mulberry and many other fruit and shade trees. 



Phoetaliotes Scudder. 



Body elongate, rather slender, a little compressed, very feebly pilose, 

 including faintly the tegmina and legs. Head large, full, prominent, 

 relatively elongate, nearly half again as long as the prozona, the space 

 behind the eyes fully half as long as the breadth of the eyes, the genas 

 a little tumescent, the head apart from the eyes slightly broader than 

 the pronotum; vertex prominent and well arched both longitudinally 

 and transversely; face a little oblique; eyes rounded broad oval, moder- 

 ately prominent, subtruncate anteriorly, moderately distant, somewhat 

 farther apart than the greatest width of the frontal costa; fastigium 

 very faintly sulcate, almost plane; frontal costa prominent, markedly 

 narrower above than below the ocellus; antennas slender, moderately 

 long, but shorter than the hind femora, though fully twice as lon» as 

 the pronotum. Pronotum of moderate length, faintly subsellate but 

 otherwise equal, feebly flaring in front to receive the head; disk 

 rounded subtectate, with broadly rounded, very indistinct lateral carina, 

 and a sharp, equal and percurrent median carina; prozona longitudinal, 

 nearly half as long again as the metazona, with indistinct transverse 

 sulci; front margin subtruncate, hind margin extremely obtuseangulate. 

 Prosternal spine rather large, erect, conical, blunt, mesostethia and 

 metastethia together much more than twice as long as broad; interspace 

 between mesosternal lobes much (male) or little (female) longer than 

 broad, the metasternal lobes attingent (male) or approximate (female) ; 

 portion of metasternum behiifd the lobes about twice as broad as long 

 and about half as broad as the greatest breadth of the metasternum. 

 Tegmina either abbreviate, broad lanceolate, acuminate, attingent, 

 slightly longer than the pronotum, or fully developed, surpassing the 

 hind femora, rather broad and equal, well rounded at tip, hardly taper- 

 ing in the distal half, at a distance from the apex equal to the breadth 

 of the tegmina as broad as the metazona; the intercalaries and cross- 

 veins of the discoidal area everywhere few, the venation in general 

 loose, irregular and ill defined, the humeral vein broadly sinuous, ter- 

 minating on the costal margin at least as far before the apex as the 

 breadth of the tegmina, nowhere running closely parallel to the costal 

 margin nor gradually merging into it; the area intercalata not reach- 

 ing the middle of the .tegmina. Hind femora long and slender, the 

 genicular lobes pallid with a transverse basal fuscous stripe; the hind 

 tibia glaucous, sometimes yellowish, with eleven to thirteen spines in the 

 outer series. Abdomen compressed, mesially carinate, apically clavate 

 and recurved in the male, the subgenital plate narrow and long, with 

 lateral margins ampliate at the base, the apical margin mesially pinched
