caudal femora by about tho Iciifitli of the pronotal disk: (-ostal marf;;in of the 

 tegmina very faintly lobulate and .subarcuat(> proxiuiad, straight for the median 

 three-fifths of the length, the distal extreniity of this margin strongly arcuate 

 to the narrowly rounded, but in general aeute-angulate, apex, which is nearly 

 sutural in position; sutural margin straight: reticulations of the tegmina 

 fewer and more ojien than in bimaculala. Prosternal tuliercle less elevated and 

 less mamillate than in himaculata. Ovipositor jaws shorter, more rol)ust and 

 less elongate than in bimaculala, the distal extremity of the dorsal valves 

 more sharply upcurved, the ventral valves with the distal section more decurved. 

 Limbs as in bimaculala but somewhat shorter; the caudal tarsi are also some- 

 what heavier. 



Allotype. — cf ; Same data as the type. [Acad. Nat. Sciences 

 Phila.] 



This ^ex differs from the male of himaculdld in the broader tegmina, which are 

 slightly broader than the greatest (caudal) width of the pronotal disk; stru('ture 

 of the tegmina as in the type. Limbs agree with the description of the female. 



General color lime green to light cress green, on the ventral surface and limbs 

 passing to ecru olive or even old gold; tegmina washed in a tessellate pattern 

 with pale green-yellow, the areas of the general color on the tegmina being 

 relatively small, quadrate and evenly distributed. Usual spot at base of anal 

 field of tegmina orange chrome. Wings with the veins of the anterior field 

 washed with the general color, and of the remainder weakly lined with pale 

 garnet brown. Eyes brussels brown ( 9 ) to bay (cf ). Antennae dull garnet 

 brown. Caudal tibiae becoming more intense coral pink to light jasper red 

 distad, the spines very narrowly black tipped. Vestiture whitish. 



Measurements {in millimeters) 



In addition to the type and allotype we have exaniined a para- 

 typic female.
