2. Heliria scalaris Fairmaire. 



Here the anterior foliole of the crest is abruptly elevated 

 to about twice the height of the posterior and is distinctly in- 

 clined forward as in cristata. While in Colorado I took two 

 examples that I cannot separate specifically from scalaris. They 

 have the anterior foliole vertical, rounded, and but little elevated 

 above the posterior to which it slopes at an easy angle. The 

 color is more grey with a broad brown vitta on either side which 

 covers the crest. The typical form was taken by Dr. Fitch on 

 the beech and described by him as Telamona fagi. I have 

 taken the males on thorn bushes but there were beech trees 

 near by from which they may have flown. It seems to be a 

 rare form. 



Genus Telamona Fitch. 



The insects of this genus are rather above medium size 

 with a remarkable development of the pronotum which makes 

 them interesting objects of study and as a consequence a large 

 number of species have been described. My material in this 

 genus is not extensive and it is sometimes difficult to say what 

 characters should be considered as of specific value. I there- 

 fore have not attempted to make a critical study of the synon- 

 omy, contenting myself with placing a few synonyms of which 

 I feel reasonably certain. The synoptical table given below is 

 founded mostly on the form of the pronotum and other super- 

 ficial characters and with the notes and descriptions following 

 refer only to the species known to me. But as they include 

 most of those more commonly met with it is hoped that they 

 may be of some assistance in the determination of these species 

 and in connecting them with the synonomy used in the appen- 

 ded list. A more careful study of the genus is needed and I 

 understand is soon to be undertaken. 



Crest vertical, rather slender and narrowed upward, i. 



Crest if vertical broader, but little narrowed above, 2.

 ken at the hind angle; front nearly vertical,
