Mr. Schwarz asked Mr. Heidemann how much is known 

 of the eggs of Aradidae. Mr. Heidemann replied that little is 

 known concerning the eggs. He himself had found eggs of 

 only one species, namely, Neuroctenns simplex Uhler. These 

 were under the bark of oak and resembled the eggs of the bed 

 bug. Mr. Sanders stated that he had found eggs of Aradus 

 cinnamomeus Panz. under loose bark of Pinus inops. They 

 were placed in a cottony nidus resembling that of Pulvinaria. 

 Doctor Ashmead stated that he had never found Aradidae 

 under living bark, but he had found them under the bark of 

 orange trees killed by frost, in Florida. Mr. Heidemann stated 

 that on two occasions he had found Aradus breviatus Bergroth 

 under the living bark scales of pine trees near Washington, 

 D. C. Mr. Burke gave it as his belief that one of the western 

 species, Aneurus simplex Uhler, occurs under scales of bark 

 of living spruce trees. 



The following paper, by Dr. G. W. Harvey, of Adin, Cal., 

 was then read by the recording secretary : 



A FEROCIOUS WATER-BUG. 



(Pedinocoris macronyx Mayr.) 

 By G. W. HARVEY, M. D. 



In the warmer streams and ponds of California lives a crea 

 ture whose character is aptly portrayed by the word ferocious. 

 He might be termed a giant for his fierceness and strength 

 were it not for the fact that the so-called electric light bug is 

 a neighbor of his and about twice his stature. Among the 

 children who go wading in the streams this bug is known as 

 " toe pincher," because he frequently mistakes their toes for 

 lawful quarry and thrusts savagely into them with his scimitar- 

 like proboscis. They tell me that his bite is very painful, 

 though not at all dangerous. 



Scientifically this bug bears the title of Pedinocoris ma 

 cronyx. It is of a uniform dull brown color, with a barely 

 perceptible mottling on the elytra. The females are possibly 

 a shade darker than the males. It has protruding beady black 

 eyes, and its head terminates in a long curved proboscis about 

 7 millimeters in length, which gives it a very odd and savage 

 appearance. Its legs are hairy, and armed with sharp curved 

 claws, very long and prominent on the two front legs, which
