The performance of a fixed trap cannot be compared quantitatively with other traps. However, there is little doubt that the Lepidoptera catches are comparable with those that might be expected in an opaque trap, using the same light source. The catches of Scarabaeidae have been consistently low, even in the middle of their flight periods and, as most are segregated from the catches of Lepidoptera. the quality of the latter has remained high. The size of the killing chamber and the ample floor area of the trays tend to prevent further damage to specimens which fly actively before death. An unexpected feature of this trap is that it collects a variety of terrestrial arthropods, including apterous and brachypterous insects, which are not normally taken in light traps. These include the first known specimens of certain brachypterous Oecophoridae, as well as caterpillars, centipedes, scorpions and spiders. Even small lizards have occasionally been taken.

A RANGE EXTENSION TO MISSOURI FOR MONODES GEORGEI
(NOCTUIDAE)
During the first and second weeks of May 1962 I collected at black light a series of noetuid moths which were later identified as Monodes georgei Moore & Rawson by Dr. A. E. Brower. The range of this rather recently described species is given as Quebec, Nova Scotia and Livingstone Co. Michigan (Forbes, Lepid. N. Y. and neighboring states, part 3; 1954). Specimens were collected at several points through the Missouri Ozarks from Oseola in St. Clair County to Warsaw in Benton County. The species is an apparent native of the Ozark fauna as the flight time is a full month ahead of the northern population making a migration from that area impossible. These records extend the known range of georgei to the lower edge of the Upper Austral Zone. Whether the species exists as a relict form on the Ozark Plateau is an interesting question. To date I have been unable to learn of any records from the intervening area.
