the more expanded and snblaniellate supra-coxal expansions of the 

 same, the more strongly lobed limbs and abdomen and the distinctly 

 emarginate marginal field of the tegmina. The Arizona specimens 

 of Vatcs recorded by Caudell as T''. townsendi?^ may probably be this 

 species and not townsendi, which has stronger pronotal expansions 

 in the female than we would suppose were possessed by the female of 

 the species figured. 



The only previous records of this species north of Panama were 

 from Guadalajara, Jalisco, and Cuernavaca, Morelos, Mexico. 



ACRIDID^. 



Telmatettix aztecus (Saussure). 



Tucson, 1 9 . Baboquivari Mountains, 2 cJ*, 3 9 . 



These specimens have been compared with Yautepec, Morelos, and 

 Teocelo, Vera Cruz individuals. 

 Clypeotettix schochii (Bolivar). 



Baboquivari Mountains, 1 9 . 



This specimen is inseparable from Morelos and Vera Cruz specimens, 

 and constitutes the first record for the species from the United States. 



Paratettix toltecus (Saussure). 



Tucson, 3 fo . 



Specimens from Arizona, New Mexico, Mexico, Nicaragua and Costa 

 Rica have been used for comparison. 

 Achurum acridodes (StM).-^ 



Baboquivari Mountains, 1 c?. 



Mermiria neomezicana (Thomas). 



Baboquivari Mountains, 1 c^. 



This is the first Arizona record of the species, which ranges south as 

 far as the State of Durango.

In many respects this species appears to connect the two types 

 previously known in the genus, i.e., occipitalis and crenulata. From 

 the former type {occipitalis, cinerea and afjinis) it can be separated by 

 the more strongly bowed lateral carinse of the pronotum, narrower 

 tegmina and the distinctly slenderer caudal limbs. From crenulata 

 the new form can readily be distinguished by the larger size, the 

 slenderer and less inflated head, more retreating face, narrower teg- 

 mina and longer limbs.
