Color brown, connexivum3 spotted; length 6.5 mm (fig. 5) .4 microphthalrnus FIor. 1 The frena are longitudinal grooves in the edges of the scutellum which receive the inner margins of the hemielytra. They end about where the clavus disappears beneath the scutellum. 2 In the latest general catalogue (Kirkaldy, 1909) the Acanthosomatinse and Graphoso- matinse are given as tribes of the Pentatominse. This matter is still open to discussion, I believe, but in the present series I plan to follow the check-list of Van Duzee, to whom I am again indebted for advance information.
aThe marginal region of the abdomen.
There are very few records of the occurrence of Sciocoris in this country, and collectors should be on the watch for it. 4 The ocelli in this species are very small and unfortunately do not show in the figure.
