color. As the mothers of these young Periplanetas were dead 

 long before they came into the world, it is not probable that the 

 offspring ever receive maternal care or protection. 



Mr. Lancaster Thomas exhibited a net frame made of a con- 

 tinuous piece of aluminum wire. The coiled ends of the wire so 

 twisted as to form a threaded arrangement into which a handle 

 might be screwed. It was very inexpensive, costing only fifteen 

 cents. He further stated that he believed a round net frame 

 preferable to one made from material like a clock-spring, as 

 the latter had a tendency to cut off leaves and twigs and thus 

 fill the bottom of the net with debris. Mr. Westcott showed a 

 substitute for cork to be used in boxes or drawers. It is what is 

 known as linoleum, and he believed it to be preferable to cork. 

 Mr. Wenzel suggested that if it would corrode the ends of the 

 pins it would interfere with its usefulness. Dr. Skinner called 

 attention to a material known as Polyporus betulinus, a fungus, 

 which could also be used for the same purposes as cork as far as 

 entomology is concerned. Mr. Fox stated that he had been 

 studying the Hymenoptera caught in Northeast Africa by Dr. A. 

 D. Smith, and presented by him to the Academy. There were 

 about ninety species, of which perhaps a half dozen were new to 

 science. Dr. HENRY SKINNER, Recorder.

PRELIMINARY NOTES ON FIVE NEW SPECIES OF 

 SCALE INSECTS. 



By W. G. JOHNSON, University of Illinois, Champaign. 



The Elm Chionaspis (Chionaspis americana). This species is 

 very abundant throughout Illinois on white elm ( Ulmus ameri- 

 cana), and as I believe it is a native American insect, I have so 

 named it. It has been very abundant and destructive to shade 

 trees in our cities throughout the State the present season, and 

 is also very common on native timber in central and southern 

 Illinois. The scale of the female is larger and more convex than 

 that of the scurfy bark-louse, Chionaspis furfnrus, is yellowish 

 brown at first, but becomes lighter with age and exposure; those 

 that remain over Winter shielding the purplish eggs become 

 nearly white by Spring. The male scale is pure white and does
