Oncocnemis saundersiana Grt. The young larvae of this species were first found at Bobcaygeon, Ont., in June, 1931, feeding within the blossoms of a Pentstemon sp. but died before reaching maturity. At the same time and place in 1932 a number of more fully grown larvae were secured, either feeding on the blossoms or resting flat against the main stem of the plant; the larvae are smooth, slender and of a pale green color, variably suffused with a pinkish shade, exactly matching the Pentstemon blossoms, and at times they may be entirely pink, especially in those instances where the caterpillar is resting on the flowerheads. Pupation takes place in the earth and the moth emerges in late August.
