joint. Eyes moderately prominent. Antennae somewhat longer than the 

 body; proximal joint much enlarged, the internal face with a distinct rect- 

 angulate projection, when seen in dorso-ventral view. 



Pronotiun of the general type foimd in the genus, the dorsum well separated 

 from the lateral lobes by very evident, though narrowly rounded, angles: 

 disk of the pronotum in general flat, nearly one-half as long as the ovipositor 

 and nearly equal to two-fifths of the length of the caudal femora; cephalic 

 width of disk faintly more than two-thirds the greatest width of same, which

is at caudal fifth; greatest constriction, which is at cephalic fourth, but slightly 

 less than cephahc width; cephalic margin of disk moderately concave; caudal 

 margin of same flattened arcuate, mesad with a very faint concave sinuation: 

 lateral carinae of disk very weakly clepsydral; median carina of disk not 

 evident cephalad, very faintly indicated caudad; metazona about one-half 

 as long as the prozona; cephalic transverse carina at cephalic fifth, very 

 obtuse-angulate. Lateral lobes of pronotum weakly expanding ventrad ni 

 transverse section; dorsal length of lobes contained nearly twice in their depth: 

 cephalic margin of lobes weakly oblique truncate, ventro-cephalic angle
