position; caudal tibiae more or less completely infuscate with bone 

 brown. 



General color of female (unstuffed specimens) olive ochre to honey 

 yellow, finely punctulate with maroon, these punctulations thickest 

 on the dorsum of the abdomen and practically absent from the face, 

 gense, and lateral lobes of the pronotum. Limbs varying from 

 uniform apple green to the general color, more or less suffused with 

 Vandyke l^rown. Pale lateral bars hardly indicated or weak in the 

 female, tegmina almost wholly of the same tone. Ovipositor of the 

 general color, suffused distad with sepia to brownish black. 



Distribution. — The range of this species covers a considerable area 

 of Texas south and east of the Edwards Plateau and plateau plains, 

 being known from four localities, viz., Dallas, Gregory, Beeville, and 

 Uvalde. Dallas constitutes the northern and eastern limit of its 

 known range, Gregory the southern, and Uvalde the western. The 

 vertical range of the species is from practically sea-level at Gregory 

 to eleven hundred feet elevation at Uvalde. 



Biological Notes. — All we know regarding the habits, etc., can be 

 taken from our own notes, based on the capture of three specimens. 

 At Gregory we obtained the species from a green tangle about a 

 mesquite clump, where D. hrevihastata was also secured; at Beeville 

 it occurred in weeds near a tangle of low vine-covered bushes, while 

 at Uvalde it occurred with D. castanea on Acacia berlandieri growing 

 on the low hill slopes. 



Morphological Notes. — The male cerci seem to be very constant in 

 form, but the distal margin of the male subgenital plate shows 

 considerable variation, in some specimens (Dallas) considerably 

 approximating D. gladiator in this respect, from which species, 

 however, cereal and other characters readily separate them. This 

 variation is due to a certain amount of plasticity in the shape of this 

 margin, which ranges from distinctly rectangulate emarginate (as it 

 is in the majority of specimens) to a type which has the angulation 

 obtuse with the lateral angles much more rounded than in the 

 typical form. 



In the female the ovipositor shows some variation in the straight- 

 ness of the ventral margin, this being slightly arcuate in three Dallas 

 individuals, but this arcuation is not as decided as in gladiator, the 

 general form and robustness of the ovipositor being different from 

 that found in the latter. In two Dallas females the tegmina are 

 hardly visible beyond the pronotum, l)ut the specimens are unques- 

 tionably adult. The tegmina project slightly caudad of the adjacent
