low at base, deepening" toward apex ;clypeiis tricarnate, median 

 one obscure ; pronotum short, sinuously, angularly emarginate be- 

 hind ; scutellum a little longer than wide, lateral angles slightly 

 behind middle ; central carina obscure ; lateral carinae well ele- 

 vated in middle, appearing as two small, longish tubercles. Teg- 

 mina differing from Phaiifasiiiafoccra in having the first median 

 section forked and the cubitus simple. This genus comes near 

 to Sz'.'cj:cyia and Pliantasinatoccra.

Kirkaldy erected this genus for two species, arbor ca (type) and 

 viticnsis : subsequently he erected a new genus, Ncsophantasma, 

 for the latter species.. I now have two species which agree with 

 Pliantasinatoccra, all the specimens being males, and nine species 

 which agree with Ncsophantasuia, all the specimens being fe- 

 males, two of which agree in all details, except the shape of the 

 head, to P. arhorea and P. nigromaciilata. The two species, la- 

 lokcnsis and papitcnsis, are only represented by females and the 

 shape of the head is intermediate. I believe that this is a genus 

 with slight sexual dimorphism in the shape of the head and that 

 Kirkaldy was correct in his original decision, which I revert to.

( 9 ) The marking agree with the male. Vertex very slightly 

 narrowing toward apex, sides very slightly sinuous, face subpar- 

 allel sided, antennae reaching slightly beyond eyes, smaller than 

 in male ; ])osterior margin of last ventral abdominal segment 

 widely angidar, the apex produced into two small points, turned 

 somewhat ventrally, in profile angular near base.
