robust build and the heavier cephahc aiid median femora. The form 

 of the subgenital plate closely resembles that of bihastatus. 



Size rather large ; form more robust than usual in the genus ; surface 

 of thorax, head and limbs distinctly punctate, abdomen very obscurely 

 punctate. Head acuminate; rostrum about half as long as the 

 remainder of the head, tapering, apex blunt, carinate distinct but not 

 sharp; eyes elliptical ovate, rather prominent; antennae about twice 

 as long as the rostrum, basal joint but slightly more than half the length 

 of an eye. Pronotum with a slight median supracoxal dilation; 

 cephalic margin roundate, shallowly emarginate mesad; caudal margin 

 sinuato-truncate. Mesonotum and metanotum moderately inflated, 

 strigse distinct and serrato-dentate. Supraanal plate acuminate, 

 apex moderately acute, proximal half with a shallow median emargi- 

 nation; subgenital plate produced, needle-like. Cephalic and median 

 limbs similar, the cephalic pair slightly smaller than the median. 

 Caudal femora elongate, reaching to the middle of the fifth abdominal 

 segment ; caudal tibiae with thirteen spines on the external and twelve 

 to fourteen on the internal margins. 



General color pale apple-green, suffused dorsad, on the ventral surface 

 of the rostrum and on the entire dorsum of the abdomen wdth olive.
