Identification

"Very similar to hamatus; the chief differences as in key. Color variable, the head and pronotum often reddish-brown, sometimes with front half of latter black and hind one brown. Membrane blackish with a large oval or rounded yellowish spot at middle. Connexivum in both sexes with wide alternate blackish and yellow spots; legs usually reddish- yellow, paler at base, often in great part blackish....

Both (biguttatus and hamatus) vary widely in the yellow markings of elytra and legs. The only structural difference between the two seems to be the narrower form of the males of hamatus."(1)
