1. Platystolus SURCULARIUS, Bolivar. 



Big and fat, green or olive. Length of body, 35mm. 3 , 37mm. 

 $ ; of pronotum, 10mm. 3 , 9mm. $ ; of posterior femora, 19mm. 

 3 , 21mm. J ; of ovipositor, 30mm. 2 . 



This species occurs on thorns and spiny shrubs in .July round 

 Madrid, extending as far as Alcala, Ucles and Ciudad Real. It is 

 doubtfully recorded from Troia in Portugal. Father Pantel observes 

 that specimens occurring on Scolynnis hispanicus are green. 



2. Platystolus martinezi, Bolivar. 



Distinguished by the unspotted femora on unspined abdomen. 

 Length of body, 36mm. -38mm. 5 and 3 ; of pronotum, 9mm. 3 

 and 2 '■, of posterior femora, 22mm. -23mm. 3 and $ ; ovipositor, 

 28mm. 2 . 



Common round Madrid, extending as far north as Valladolid. 

 Bolivar notes that specimens from San Martin de Valdeiglesias 

 in July were crammed with (Jordins : these were all found on perfectly 

 dry and arid ground. The natives call them " Papahigos." 



Genus : Pycnogaster, Graells. 

 This genus includes large, plump, apterous grasshoppers, difi'ering 

 from the preceding in the absence of the apical spine on the inner 

 border of the posterior tibiae ; the pronotum is Hat above, with a keel 

 on each side which extends from the anterior to the posterior border, 

 separating the disc from the side Haps. The prosternum has two 

 spines. 



In Europe, the genus is confined to Spain, and the discrimination 

 of the species is difficult.
