 its median portion.

 spaced, black annuli. Disk of pronotum cinnamon, deepening 

 laterad, and caudal margin bister, margined laterad with buff 

 yellow. Cephalic coxal spine white, with a round ventro-mesal 

 spot of black. Tegmina greenish chamois, the areolae with 

 mottled suffusions of light cendre green, which become very incon- 

 spicuous and olivaceous in shade in distal portions. All tibiae 

 distad with a brown fleck on dorsal surface. Third joint of tarsi 

 with lateral lobes embrowned. 



Length of body 18.3, length of pronotum 3.7, length of tegmen 

 27, greatest tegminal width 7.8, length of cephalic femur 5.8,

The type of this distinctive insect is unique.

The general coloration of this remarkable species is a very light 

 milky green. The male before us is immaculate, except that the 

 tegmina have a black spot in the second areola of the anal field 

 beyond the enormous stridulating area, toward the anal vein, and 

 the subgenital plate is shining black with styles, however, pale. 



The female here recorded is marked with hay's russet, as figured 

 by Brunner, the markings of the tegmina being, however, less 

 heavy.

 cephalic femur c? 12.5, 9 14; length of caudal femur cf 23, 9 24.6; 

 length of ovipositor 16.5 mm.

 very generally incorrectly used for the genus which should be recognized as 

 Morsimus. See notes on generic confusion, page 188.
