MEASUREMENTS OF CALOPTENUS FEMUR-RUBRUM. 



51 



segment is a rather large transverse gash-like indentation. The cerci are about the same 

 length as those of the male spretus and about the same width at the base, but are nar- 

 rov?ed from the middle to the tip to about' half the width at the base. The little tooth- 

 like appendages at the base of the super-anal plate are elongate and slender, as in 

 spretus and are sinuate.

A few additional measurements of last year's specimens : 



Female— 1.21. 1.23. 



Male— 1.05, 0.94, 1.02, 1.05, 1.07, 1.07. 



In addition to the characters mentioned in the original description of 

 C. atlaniSj we would call attention to the following differences between 

 it and spretus on the one side ^ud femur -rubrum on the other. 



Female. — ^As compared with the female of spretus the wings are 

 shorter, extending less and sometimes beyoud the tip of the abdomen, 

 not differing greatly, in this rCvspect^ from femurruhrum; the elytra 

 are narrower, curved upward very sliglitly at the apex, very few spots 

 or dots on the apical portion, and these minute and dim. The iuufr 

 field is almost always immacuUite, the posterior half of the iutercala-te
