26 PROCEEDINGS OF THE ACADEMY OF [Feb., 



and elegans Giglio-Tos. Of these punctata is the oldest known and the 

 most widely distributed species, and may be considered the type. 



The species of this genus are quite difficult to separate and the recogni- 

 tion of almost all the forms can be considered only tentative. The extent 

 of individual variation is great, both in structure and color, and reliable 

 characters for the separation of species are iew. The work of Bruner 

 in the Biologia is by far the best treatment of the genus so far published.

This series shows that the species varies somewhat in size (males 

 from 16 to 21 millimeters in total length), but little in color. All 

 except one d^ from Jalapa are of the same colors, allowance being 

 made, of course, for fading in the Sumichrast specimens, while the 

 Jalapa exception has the usual green dorsum replaced by a dull olive 

 tint, while the pronotum near the lateral lobes is not as distiactly 

 marked as in the other specimens. 



The ? specimen measures as follows: length of body, 22 mm.; 

 length of pronotum, 4.1 ; length of tegmen, 17; length of caudal femur, 

 12.9. 



This species seems to be a form limited to the Eastern Cordilleras. 



Orphulella aouleata Rehn. 



1900. Orphulella aculeata Rehn, Trans. Amer. Entom. Soc, XXVII, p. 92. 

 [Cuernavaca, Morelos, Mexico.] 



Cuernavaca, Mexico. June. 1 c^, 3 9 9 including types. (0. W. 

 Barrett, A. N. S. P.) 



This species appears to be quite distinct, and is not an Orphulina 

 as has been thought possible by Bruner.^ Superficially this form 

 considerably resembles 0. viridescens Scudder, but the structural char- 

 acters are quite distinctive and show that no close relationship exists.
