Idiocerus pacificus

Resembling ensiger Ball in structure but not as definitely marked; resembling musteus Ball in color and markings but the female tawny with a long ovipositor and the male with long lateral lobes on the ultimate segment and obovate antennal discs. Form of ensiger nearly, the face deeper and more inflated, the ovipositor long but not quite as long as in ensiger . Male ultimate segment with lateral lobes elongated, not short as in musteus which it resembles in color. Male antennal disc moderately large, obovate. Color of female tawny, the face mottled and with white circles around the black spots on vertex and a median white V, three light areas on pronotum, the median one elongate, scutellum pale creamy with tawny or dark triangles, elytra cinereous with a tawny cast and the nervures becoming smoky toward the tips, and with a definite white line along claval suture. Male dull cinereous with dark triangles on scutellum, dark spots on pronotum, and a white face. (Ball & Parker, 1946) This species was mixed with verrucosus and musteus in collections but can be readily separated by the long ovipositor in the female and the obovate antennal discs in the male.
