specimens which seem to be intermediate between regularis and 

 relidus, the interspaces become more and more wavy, until the 

 striae are no longer regular and entire, but broken up as in 

 relidus. 



The following might be suggested as a revised description 

 of regularis : Form and general appearance of C. relidus, ex- 

 cept on the elytra which have 1 2 impressed punctured striae, 

 generally regular and entire. The thirteenth is composed of 

 separate punctures confused with the marginal ones ; inter- 

 spaces somewhat wider than the striae, the fourth and eighth 

 being generally interrupted by from four to eight punctures, 

 and one or two interruptions occasionally occurring on one or 

 more of the other interspaces, especially on the 7th, 9th and 



nth.

A New Method for Permanently Mounting Insects. 



By Prof. O. B. Johnson, Seattle, Wash. 

 To the Brethren of the Net ! 



Just a few words about a new method of permanent 

 mounting for insects that I have been experimenting with 

 and that seems valuable.' It consists of a box or case made 

 in two parts with pasteboard sides or rim, and with top and 

 bottom of glass. These glasses are both of the same size, the 

 bottom one fitting flush with the outside of the rim, while 

 the top one fits inside the cover rim, so that the two parts 

 "telescope" together. These cases are ^ inch deep inside, 

 and of sizes increasing in length by inches from 3 to 12, and in 

 width by ^ inches from i]/?, tO any width desired. These 

 sizes are easily fitted into 12 or 18 inch drawers of ^ or i inch 

 depth — thus in the 12 it takes i, 12 ; 2, 6s ; 3, 4s ; 4, 3s or 9 

 + 3, 8 + 4, 7 + 5. The insects are mounted in the conven- 

 tional position, J + 9 side by side in the same case on a short 

 piece of 00 pin inserted in the usual manner into the thorax, 

 only from the underside. This pin in turn is inserted into a 

 bit of cork that is finally fastened to the bottom glass by a 

 touch of Le Page glue. These cases can be made by any box 

 factory, just what the cost would be will depend upon the place.
