362 NEW TROPICAL AMERICAN ORTHOPTERA 



General color of head, antennae, ventral surface, abdomen and limbs ochra- 

 ceous-buff, of the tegmina mignonette green, passing to lime green in the vicin- 

 ity of the distal half, the veins mesad and proximad pencilled with ochraceous- 

 buff. Eyes tawny-olive. Pronotum ochraceous-buff, overlaid with weak 

 wash patches of lime green and clear fluorite green. 



Length of body, 18 mm. (body somewhat distorted); length of pronotal disk, 

 5.6; greatest (caudal) width of pronotal disk, 5.4; length of tegmen, 26.5; 

 greatest width of tegmen, 23; length of caudal femur, 16.2. 



The type of this species is unique. 

 Paralobaspis gorgon new species (PI. XIX, figs. 11, 12 and 13.) 



This striking new species is closely related to the genotype, 

 P. 'pida Giglio-Tos, '^ described from the Valley of Santiago, 

 eastern Ecuador, agreeing in the general features of its structure 

 and also in the general color pattern, but differing in its ap- 

 preciably larger size, in the proportionately shorter pronotum, 

 which also has the caudal margin of the disk broadly truncate, 

 instead of moderately produced and rotundate as in -pida, in 

 the proportionately shorter caudal femora, in the ovipositor 

 being but weakly falcate, in the subgenital plate being V-emar- 

 ginate with decided lateral angles, instead of triangular and fis- 

 sate as in pida, and in numerous details of the coloration. From 

 P. personata Rehn, recently described ^^ from northeastern Brazil, 

 the present species differs in numerous features, such as its very 

 much greater size, far more elongate flight organs, straighter 

 ovipositor, as well as general coloration.

 (H. S. Parish.) [Academy of Natural Sciences of Philadelphia, 

 Type no. 5286.] 



Size large (for the genus) : form moderately compressed : surface glabrous to 

 polished, the latter on limbs, head and most of pronotum. 



Head with occiput subhorizontal, faintly arcuate: fastigium moderately 

 elevated, arcuate dorsad in profile, recurved spiniform distad, the paired 

 ocelli large and the fastigium of the vertex connected with the face by a verti- 

 cal, strongly carinate ridge; median ocellus large, shield-shaped: face retreat- 

 ing, slightly arcuate dorso-ventrad, transversely flattened ventrad: palpi 

 with the third joint subequal in length to the fourth, gently arcuate; fourth 

 palpal joint straight, as a whole more slender than the third; fifth palpal joint 

 one and one-half times as long as the fourth, straight, slender proximad, 

 moderately enlarging distad: eyes moderately prominent when seen from the
