INSECTA SAUNDERSIANA. 
Rostrum at least as long- as the head, subtriangularly ampliate, flat 
and ohsoletely punctulate at the apex; base with two canaliculations 
passing through the narrow forehead and beating a little on the vertex, 
and between them an elevated line broadened towards the antennae ; 
head subconicallv-cylindric, much longer than wide, smooth above, with 
a thin eanalicula posteriorly, very slightly strigose laterally. Thorax 
hardly shorter than its basal width ; ampliation of the sides subacute 
behind the middle, especially in the male; less convex and smoother in 
the female, hardly inclined anteriorly. Elytra subtriangular, convex, 
not inclined longitudinally from the base to the middle, then semi- 
circularly bent to the apex. 
Varies in coloration : some specimens have the head and thorax 
only a little darker than the elytra, with no greenish hue; in these, the 
antennae, abdomen and legs are more rufescent, especially the four 
hinder legs, as is generally the case, the reverse being abnormal.
