sinuate near the center ; in the allotype the last ventral segment is narrowly 

 notched, the notch extending only half way to the base. Uncus when viewed 

 in profile arched above, sinuate beneath, and when viewed from above notched 

 ait the extremity. 



Head black above, supra antennal plates and an irregular area behind the 

 ocelli, green. Pronotum green variegated centrally with black, especially in 

 the depressions or grooves. Mesonotum green with four obconical black spots 

 along the anterior margin, the outer pair about twice as long as the central 

 pair; from the central pair extends a black line backward to the elevated X, 

 where it either forks or is represented by two spots. There are also two black 

 spots, one near each of the anterior extremities of the X. There is an irregu- 

 lar black line extending each side from the elevated X to the base of the fore 

 wings. Metanotum green, irregularly spotted with black near the base of each 

 hind wing. Front wings with the venation conspicuously black, except the 

 yellowish-green front margin, the clouded green basal cell, and the green veins 

 surrounding the anal area. In the hind wings the marginal cells are sur- 

 rounded by more delicate blackened veins, while the venation on the basal half 

 of the wing is greenish, the anal areas being opaquely greenish-white. Mem- 

 branes at base of both pair of wings are greenish-white, those of the front 

 wings slightly yellowish on posterior margin. Abdomen green above with the 

 commencement of a black dorsal vitta on the first segments, a rather con- 

 spicuous black stripe on the front margin of segment three ; less conspicuous 

 ones on segments two and four, or the last may be wholly wanting. In addi- 

 tion segments three to six have two black spots on each side, the upper rounded 

 and the lower linear in form. In the allotype there is an irregular black spot 

 each side on segment nine. Uncus green, blackened along lower margin. Be- 

 neath, 'the head is black, the frontal sulcus partly green, the terminal part of 

 the rostrum black, the legs green striped with black, claws and spines tipped 

 with black, abdomen green with the usual basal dark spot, which in this in- 

 stance is much reduced ; valve green.

In addition to the type and allotype two males were collected at 

 Upland, California, one July 20, and tlie other July 29. 1920. Miss 

 Hewlett writes : " One which I caught was singing more like a 

 Katydid; not a steady song." In some of the species of Okanagana 

 the song is quite steady.
