Abstract
Previous descriptions of the fullv grown larva of Polites themistocles Latr. are based almost wholly on a single specimen reared by Fletcher (Scudder, 1889). Last year when twenty-three of these larvae were bred to maturity, certain very conspicuous characters of diagnostic value were noted which were not mentioned in the early account. Since this species may be recognized easily by characteristic patterns on the head and anal plate, it is felt that these should be brought to attention.
