66 STUDIES IN NORTH AMERICAN MEMBRACID.E 



nearly black and is invaded by an extension of the pale ground 

 color on either side at base of the crest, and the pale posterior 

 ray is extended to either margin as a transverse vitta. Both of 

 these pale extensions are indicated in the paler New York 

 specimens. 



It is possible that this may prove to be the male of some 

 previously described species but I have been unable to so 

 locate it. It is very near pyramidata Uhler but the form is 

 stouter, the crest is shorter and less elevated and more trunc- 

 ated at apex. The characteristic color pattern on the pronotum 

 of this species is more or less distinctly visible in pyramidata 

 but this latter species ^has a much longer posterior pronotal 

 process. 



4. Telamona viridia Ball. 



I frequently beat this species from poplar trees at Denver, • 

 Pueblo and other localities in Colorado. It somewhat resembles 

 rcclivata in form but has the dorsal crest more as in barbata 

 only still more reduced and conical. The cabinet specimens 

 are of a clear light yellow but in life many individuals are of a 

 light yellowish green. 



5. Telamona obsoleta Ball. 



Closely allied to West cot ti Godg. but with a lower and 

 more rounded crest. I have one clearly marked female of this 

 species which was taken at Galesburg, 111. In this the head 

 has the black markings substantially as in Wcstcotti; on either 

 side of the pronotum is a sinuated blackish vitta from over the 

 inner angle of the eye, which, from above the humeral angles 

 curves elliptically to the lateral margins behind the apex of the 

 crest and is bordered with paler below; between these vittae 

 the surface is darker. In the Cornell University collection is a 

 pale obscurely marked example, apparently of this species, that 

 was taken at Ithaca, N. Y. In this species the fuscous apex of 

 the elytra is cut off obliquely outwardly on the line of the an- 

 terior margin of the' terminal areole. In both* these individuals 

 the crest is lower than pictured by Prof. Ball but I can hardly 

 doubt the determination. 



6. Telamona Westcotti Goding. 



In the Cornell University collection are two females and 

 one male that almost certainly belong to this species. One pair
