Close- ups of the insect are shown as the seventeen year cycle underground are given; the film then shows the emergence, after seventeen years of the nymph, and the development of the adult "This film really brings inaccessible raw material to the classroom. The micro-cine- matography is excellent. The close-ups of the evolution of this insect present a most vivid picture. The sound reproduction of noise made by these insects is an outstanding feature of the film "The use of a study guide is necessary as this film leaves the student in an inquisitive state of mind. This film could be used most profitably in any science classes that study this insect and more rightly fits into classes in biology."

The film follows in pictured detail, with a lecture explaining each step, the life cycle and history of this unusual insect. Through the use of time-lapse photog- raphy the shedding of the skin in several dif- ferent stages of growth is shown. "The final transition from the pupal stage to the winged insect is clearly explained and picturized. The egg-laying process is ex- plained, and the young insects are shown hatching from the eggs and dropping to the ground to begin their larval stage underground. The unusual treatment of this film and the interesting nature of its subject make it suit- able for all audiences."

"The glow-worm hatches out under a stone, and is at first a long queer-looking grub equipped with a kind of rosette of fingers which it uses for pulling itself up grass stems, or for washing its face and its innumerable legs. The male glow-worm is a handsome winged creature but the female is a plain little grub. She has however a lamp of phos- phorus just above her tail with which she at- tracts the male."

The fore and hind wings of the moth are hooked together and function as a single surface. The wings are made to move by muscles which cause changes in the shape of the body. A sphinx moth hovering at 60 beats per second. The wind stroke of a butterfly is slow and full. "An ant lion makes a forced landing. The grasshopper takes off suddenly. The 'dog- day cicada' is a good flyer as well as a loud singer. Looping the loop. Silhouettes of flies, bees, and wasps. 300 wing beats per second. At 220 strokes per second, this fly controls his direction perfectly, by differential action of the right and left wings." Ohio Ohio KILLERS. (Battle for life ser.)

A family of ants drink from a dew drop on a plant. A spider is in- troduced. Then ant lions, the natural enemy of the ant, trapping their victims by digging pits into which the ants fall. A short sequence on a grasshopper and a shell-backed bug fol- lows. "Next a wasp digging a hole, backing down into it, and pulling in a caterpillar. Then a scorpion and a cricket, with the face, the claws, and the stinger of the scorpion shown. A tarantula attacks and kills the cricket. After that, a mating scene between two black crickets. A spider attacks a centipede, and there is a fight between them, both being killed in a savage conflict. "Commentary, by Pete Smith, contains a number of facetious remarks. There is a musi- cal accompaniment containing short selections from music by Grieg, Mendelssohn, and others. "Recommended for nature study in the elementary grades, and for biology in the higher grades. The musical accompaniment may be of interest to classes in music; and some of the micro-photography may be of in- terest to classes in art."
