CARNUS HEMAPTERUS NITZSCH ON A SCREECH OWL IN ARIZONA (DIPTERA) . - In 1942 I recorded this ectopara- site from a flicker in New York State and from a screech owl in Florida, and reviewed what was known of its distribution and natural history (Bull. Brooklyn Ent. Soc., 37: 140-149). I was informed since that it was found in British Columbia and California, the details of these oc- currences to be published later by the discoverers. Mean- while I may record that it occurs also in Arizona. A collection of bird-flies, recently received from Professor George D. Butler, Jr., of the University of Arizona, con- tains 5 dealated specimens (3 males and 2 females) taken April 24, 1938, by Mr. S. L. Jacot on a nestling Arizona screech owl, Otus asio gilmani Swarth, 9 miles east of Tucson, at 2300 ft. altitude. No doubt the insect is widely distributed in North America, but overlooked owing to its small size (1.5 to 3 mm.). - J. BEQUAERT, Museum of Comparative Zoology, Cambridge, Mass.
