Joints 



Joint 9 is longest, 3 and 5 equal, 6 and 8 usually equal, 1 and 2 and 3 

 are equal and longer than any of the next five joints. The last sending 

 in the fall, when the leaves were found on the ground, had well advanced 

 females with their abdomen well filled with eggs, and when cleared with 

 potash they showed only an 8 jointed antenna as follows : 



Joints (1) 40. (2) 60. (3) 48. (4) 72. (5) 40. (6) 40. (7) 28. (8) 60. 

 Middle leg, coxa 120, femur and trochanter 240, tibia 200, tarsus 80. 

 The legs are somewhat slender, and the claws are thin, sharp, thickened 

 at the back, but not toothed as described by Prof. Comstock.

THE EGG OF THE WATER SCORPION (RANATRA FUSCA). 



BY R. H. PETTIT, AGRICULTURAL COLLEGE, MICH. 



In his " Insect Book," Dr. L. O. Howard states that the egg of 

 Ranatra has not as yet been described from the United States. It 

 is hoped that the following note may be of interest to someone : 



On June 24, 1900, the writer was so fortunate as to find a large 

 number of these eggs at Pine Lake, near Lansing, Mich. As the eggs 

 were not recognized at first, they were allowed to hatch, and the nymphs- 

 allowed to become about half-grown.
