 band extending forward from anterior elevations down median line to head ; 

 a short narrow yellow line on lateral margin just behind anterior elevations ; 

 median carina percurrent in front of anterior elevations but obsolete on 

 posterior half of dorsum ; metopidium twice as broad as high, darker in the

Subfamily Centrotinae. 

 Stegaspis insignis Buckton. 



1903. Hypsoprora insignis Buckt. Mon. Memb., p. 59, PI. 8, figs. 6, 6a. 



A long series of both sexes from Iquitos, Peru, Parintius, Brazil, 

 and Prata, Brazil, shows that the scutellum is very plainly exposed, thus 

 placing the insect m the genus Stegaspis of the subfamily Centrotinae. 

 A considerable variation in color is found, ranging from pale yellow 

 to dark brown.
