An abnormal male specimen of Cratichneumon unifasciatorius (Say) was collected on June 25, 1949, at Ames, Iowa, by Miss Shirley Sparling, a student in beginning entomology. Because of the nature of the abnormality it appears worthy of a note. This specimen possesses three pairs of wings, one pair on each of the thoracic segments (see fig. 1). Unfortunately, this condition was not noted until sometime after the insect was mounted, so that observations of the living insect and the opportunity to study the musculature were not available. The specimen is in good condition except for the left prothoracic wing which is badly torn.
