Pediodectes daedalus" new species. (PL IX, figs. 8, 9, 10 and 11.) 



This species, with P. initchelli (Caudell) and P. pratti (Caudell), 

 forms a distinctive group of the genus, striking in the heavy 

 build, broad pronotuni, short ovipositor and handsome coloration. 



Nearest relationship is with pratti, the present species separable 

 by its slightly less robust structure, much less contrasting trans- 

 verse banding of the dorsal surface of the abdomen, strikingly 

 darkened apices of the caudal femora and characters of the male 

 penultimate tergite and cerci. 



Type. — cf ; Uvalde, Uvalde County, Texas. Elevation, 1100 

 feet. August 21, 1912. (Rehn and Hebard.) [Hel^ard Collec- 

 tion, Type no. 537.] 



Size medium for this genus of large species, form robust, surface glossy. 



Vertex as in pratti, one and three-ciuarters times as broad as first antennal 

 joint, narrowing very strongly to the interfastigial suture. Pronotum as in 

 pratti, strongly convex in transverse section, there being no carina indicated 

 or definition of any kind between the disk and lateral lobes; caudal portion 

 of pronotum produced, completely covering the tegmina, with caudal margin 

 transverse, very feebly convex; lateral lobes deep with humeral sinus broad 

 but distinct. Prosternal spines well developed. 



Abdomen stout, each tergite, unlike in pratti, showing caudad a slight in- 

 tlication of medio-longitudinal carination. Penultimate tergite produced 

 caudad in two slender, slightly decurved processes which taper to the^r slender 

 apices, the intervening space very narrowly V-shaped^-, the interval between 

 the tips of these processes about three-quarters the length of one of them. 

 Cerci about two and two-thirds times as long as broad, shaft cylindrical, 

 slightly inbowed, bearing internally near the apex a triangular projection" 

 which terminates in a stout, shghtly decurved tooth, the bulk of this portion 

 slightly greater than that of the apical portion of the cercus, which is rather 

 sharply conical. Subgenital plate supplied with styles two and one-half 

 times as long as wide, the interval between these equal in length to one of 

 the styles and acute-angulate emarginate. 



Cephalic and median femora with margins unarmed except for a single 

 small spine on the ventro-cephalic margin of one of the former (in the series 

 rarely armed, the ventro-cephalic margin of the cephalic femora showmg in 

 individuals as many as two, of the median femora up to four spines). Caudal 



'1 From caicaXo^, beautifully wrought. 



!■- In the type these diverge slightly, in the paratypic male they are parallel. 

 In the series of pratti before us these processes are slightly over half as long 

 and their tips are separated by an interval equal to one and one-half tunes 

 the length of one of the processes, except in one specimen in which these latter 

 dimensions are equal. 



'3 In the paratypic male this projection is more elongated and slender, 

 eluding the terminal tooth twice as long as the apical portion of the cercus
