A large aluminum salad-ring mold is buried with its edge flush with the ground surface, and is filled with detergent water. The lantem covers the center hole and pro- vides hght all night. washed individually in clean detergent water, rinsed for a few minutes in 70%' and 90% ethyl alcohol, dried briefly on a paper towel, and pinned. This procedure prevented matting of the pubescence and wings, especially when the pinned specimen was blown upon with a strong air stream from the lips. The unattended, all- night light-traps were especially effective for trapping the small, hard-to-catch individuals, for collecting a series of a common species, and for catching individuals of species which were present in low densities. Although females are positively phototaxic at night, few were attracted into the light-traps. Probably this was due to ground-level shadows of surface irregularities and plants, and to low mobility of the females. Can pit-traps were outstandingly effective in trapping female mutillids, but either were much less effective in trapping males, or allowed them to escape after entering the traps. Speci- mens from can pit-traps had been preserved in alcohol, which is unsuitable for mutillids. Fur- thermore, some of the vials lost alcohol through their cork stoppers, thus concentrating the glue- like dissolved body fluids and dirt. All alcoholic specimens required washing in 70? and 90f ethyl alcohol, and ether, prior to pinning and identification. Nevertheless, some could not be restored adequately for certain identification be-.
