shown on the two sides of the middle line in the figure, are 

 respectively : 



5 2 21 27 3 9 5 14 18 18 7 10 10 

 5 6 15 27 2 8 3 16 13 20 6 12 16 

 The first measurement is the length of the head which is 5, 

 that is 5/1 o the length of the prothorax in both cases, the sec- 

 ond the length of the scutellum, 2 

 and 6 respectively, the third to the 

 ends of the corium (21) or elytron 

 (15), the fourth the total length 

 behind the prothorax which in both 

 cases figured is 27/10 of the length 

 of the prothorax. 



The next three pairs of measure- 

 ments give the location of the wid- 

 est part and the width of each of 

 the three regions of the body. Thus 

 the beetle, at its widest point, is as 

 wide as 18/10 of the length of the 

 prothorax and this point is 18/10 

 behind the hind edge of the pro- 

 thorax, while the bug is 20 wide at 

 its maximum width, but this point 

 is further forward, being only 13 

 back of thorax. The last three 

 numbers are the widths at the three constrictions. 



In using these numbers the length of the prothorax, ac- 

 cording to size desired, is measured along a line which will 

 serve as the middle line of the insect ; then, in order lay off 

 the other dimensions, finally connecting up these points in the 

 way an artist calls "blocking in," giving a sketch very accurate 

 in proportions. 



Mr. E. A. Schwarz, Honorary President.
