ORTHORTEBA ACRIDIDAE UICTYOPHORUS PICTICORNIS. 899 



slightly elevated carina, arcuate from the middle sulcus forward ; lateral 

 carinse obliterated on the front lobes, distinct on the posterior lobe ; trans- 

 verse incisions distinct, each severing the median carina, the posterior one 

 behind the middle ; anterior margin subangulate ; posterior margin produced 

 andiforming an angle a little less than a right angle ; the posterior lateral 

 margins extend almost in a direct (oblique) line from the lower corner to 

 the tip. Elytra and wings in the female about as long as the abdomen, 

 slightly passing it in the male ; the former reticulately veined, the veinlets 

 prominent ; in the male, these are not only longer but also broader than in 

 the female, and have the cells considerably larger in the apical two-thirds 

 than at the base or in any part of those of the female. Posterior femora 

 reaching the tip of the abdomen in the female, passing it in the male, 

 rather slender as compared with the size of the insect. Upper valves of 

 the ovipositor remarkably robust ; apex of the subanal plate of the male 

 strongly curved upward and tapering to a blunt point. 



Color (after immersion in alcohol). Head, thorax, abdomen, and legs 

 shining black, varied with bright yellow ; the yellow markings as follows, 

 a narrow stripe extending down the face on each side just in front of the 

 eyes ; face margined with yellow below ; a narrow stripe extending from the 

 tip of the vertex along the median carina of the pronotum its entire length ; 

 a stripe down each side of the head adjoining the pronotum ; posterior 

 lobe of the pronotum margined with yellow ; a triangular spot on 

 each side of each abdominal segment ; posterior femora with two narrow 

 lines above and two below the disk (carinse), and the basal half of the 

 disk pinnate with yellow. Antennae with the two basal and eight or nine 

 apical joints black, the rest yellow, but annulate with black or fuscous at 

 the tips (or joints). Elytra greenish-yellow, the cells or meshes black or 

 dark fuscous. When living the black portions are more or less greenish ; 

 the elytra are green or greenish, the meshes black ; the wings a bright red ; 

 exterior border and the broad front iuterneural space to the base fuscous, 

 with a red spot (usiially) near the apex.
