250 NORTH AMERICAN OEDIPODINAE (ORTHOPTERA; ACRIDIDAE) 



state that the Texas material represents a quite distinct new 

 species, which we here describe. 



Anconia hebardi new species (Plate XXVII, figs. 22, 23 and 24; plate

 1909. Anconia caeruleipennis Rehn and Hebard (not of Bruner), Proc. 



Acad. Nat. Sci., Phila., 1909, p. 155. [Franklin Mountains, Texas; El 



Paso, Texas.] 



A near relative of caeruleipennis (see plate XXVII, figs. 25 

 and 26, plate XXVIII, fig. 20), differing in the more rugulose 

 pronotum, which has more evident individual bullation of the 

 prozona and metazona when seen in profile, in the interantennal 

 portion of the frontal costa being narrower, the tegmina narrower 

 and with a more coriaceous structure and much more closely 

 woven venational pattern, in the more closely woven venational 

 pattern of the wings, in the rich blue, instead of weakly bluish, 

 color of the wing disk and in the more robust caudal femora.

 along Rio Grande.) [Hebard Collection, Type no. 507.] 



Description of Type. — Size moderately large; form moderately elongate, but 

 meso and metathorax relatively robust, pronotum less than average size for 

 general bulk, head small: surface of head and dorsal and lateral portions of 

 thoracic segments rugulose. 



Head with its exposed dorsal length hardly more than half that of pronotal 

 disk, the depth of head to clypeal suture no greater than that of pronotum to 

 ventral margin of the lateral lobes: occiput, vertex and fastigium evenly 

 arcuate in profile; fastigio-facial angle moderately prominent, rounded, the 

 inter-antennal production moderately flattened in profile, immediately ventrad 

 of the insertion of the antennae the facial profile is appreciably concave, thence 

 gently retreating ventrad to the clypeus: fastigium with its length and breadth 

 subequal, indicated chiefly by a pair of shallow pit-like depressions caudad 

 and a pair of triangular impressions cephalad ; lateral margins weakly indicat(!d, 

 moderately converging caudad, more decidedly converging cephalad; median 

 carina weak but apparent, connecting bj^ a weakly indicated V-shaped fork 

 with the lateral margins of the fastigium, which latter it delimits ventro- 

 cephalad: frontal costa but faintly sulcate dorsad of the median ocellus, more 

 distinctly so for a short distance ventrad of the same ; costa faintly and broadly 

 constricted dorsad at its junction with the fastigium, thence gently expanding 

 to between the antennal bases, when it is slightly Ijroader than the proximal 

 antennal joint, thence moderately narrowing around the mcHlian ocellus, sub- 

 equal for a distance to near the clj'pcal suture, where the sul)ol)solete margins 

 diverge sharply and irregularly. Eyes but moderately jiromincnit, when seen 

 from cephalic aspect with the width across them sul)C(iual fo that across 

 genae; basal outline of eye broad sulircnifonii ovate, the d<>ptli faintly gnviter
