The validity of this species appears to be somewhat doubtful, Giglio- 

 Tos himself ^ considering it a synonym of the North American 0. 

 maculipennis { = pelidna Burmeister). In this he is of course in error, 

 but it is extremely close to 0. punctata, which is so variable that 

 gracilis may only be an extreme with the lateral carinae more or less 

 obliterated between the first and third transverse sulci. The form is 

 rather more elongate, however, than in the average individual of 0. 

 punctata.

This large series of specimens, representing a verj'- considerable range, 

 I find cannot be divided into species on any one or number of the 

 innumerable characters of variation exhibited. The green and brown 

 phases of coloration, varied with maculations and distinct bars or uni- 

 form with practically no markings, and variations in the shape and 

 strength of the lateral carinae of the pronotum, in the length of the 

 tegmina and wings, in the form of the fastigium and eyes, some slight, 

 others pronounced, are all present, and on superficial examination 

 would appear to furnish good characters for dividing the series. At- 

 tempts along these lines, however, soon show how hopeless it would 

 be to erect species on even the most striking types, as intermediates 

 are present to connect them with any other extreme. 



Two specimens from Gualaquiza and Valle del Lamora, Equador, 

 received from the Turin Museum, labelled "Orphula olivacea" and 

 recorded as such by Giglio-Tos,^ are provisionally referred to this 

 species. They are clearly not 0. olivacea, as comparison with para- 

 typic material shows, and having been preserved in alcohol are badly 

 shrivelled in consequence.^
