(49.) — Orohesticus nigromarginata n. sp.— Color reddish yellow, probably 

 lighter in life, with a broad black band on each side extending along the entire 

 length of the insect, surrounding the eyes and mottling the face in front and ex- 

 tending nearly to the end of the abdomen behind, sometimes becoming obsolete 

 towards the tip. On the thorax it is very conspicuous and is broader on the an- 

 terior part. On the head it becomes diffused, and beyond the eyes exists only as 

 a fuscous mottling on the face, the mottling assuming a soraewliat perpendicularly 

 striated appearance. Vertex polished, light above with sides black. Fore tibiie 

 with three spines above and two rows of six each below. Middle tibife with a 

 double series of spines above and below and the posterior tibise spined on the 

 outer three-fourths, one series below and two above, the spines much shorter 

 than those on the anterior and intermediate tibiae, those on the lower side being 

 minute. Anterior femora with a single minute black spine on the base of the 

 outer third of tlie inner inferior carina. Middle femora unarmed. Hind femora 

 very long, swollen at base and armed on the inner inferior carina with several 

 small black spines. Oviposition nearly straight on the basal two-thirds, the end 

 slightly curved upwards, color dark reddish, apically growing darker. Length 

 of antennse, about 50 mm. ; pronotiim, 9 mm. ; anterior femora, 8 mm. ; posterior 

 femora, 27 mm. ; posterior tibise, 27 mm. ; ovipositor, 20 mm. 



Type No. 6119, U. S. Nat. Mus. 



Described from one female collected in Texas by Belfrage. 



In the collection brought home by my wife was one female of this 

 species collected at Perkins, Okla., Aug. 13, 1901. This specimen 

 has the ovipositor only 18 mm. in length, but otherwise it agrees 

 with the type. This species comes near to 0. americana Sauss., 

 but the shorter ovipositor and the different coloration will serve 

 to distinguish it from that species. The spined posterior femora 

 and shorter pronotum will separate it from 0. cragini Brun.
