Insufficient material resulted in the failure to recognize males 

 of the present insect as widely distinct from fulvesceus and the 

 unfortunate description of the sexes of distinct species as insolita, 

 the males of which represent desertae, the females the present 

 species. 



This insect is distinctive among the uniform pale species of the 

 genus in having the females supplied with fully developed tegmina 

 and wings, which, though not as ample as in the males, reach be- 

 yond the apex of the abdomen. 



The males, among the uniform pale species, agree with P. lata 

 and P. notha in the type of specialization of the median and first 

 dorsal abdominal segments; the elevations there found are slightly 

 less pronounced than in lata, decidedly less pronounced than in 

 notha. The size is decidedly smaller than in either of those species, 

 the form distinctly narrower than in lata and broader than in 

 notha, with supra-anal plate of very different form from that found 

 in the latter species. The general character of the supra-anal 

 and subgenital plates is much as in /(//(/, but the styles are decidedly 

 longer, in this respect agreeing more nearly with P. uhleriana; 

 the styles are not as elongate as in notha. In general appearance 

 nearest similarity is found in P. Jidvcsccus. 



'^•' Reconied, with a (lucstion, incorrcclly liy Caudeil as coulouiana. 



^'^■' These specimens appeared to those authors to represent the intermediate condition 

 between the supposed races tthlenana uhleriana and nhle- iana Julvescens. At that time, 

 the specialization of the dorsal surface of the male abdomen had never been considered. 



'^'■"' The male descriljcd as /. insolita has l)een selected as single type and, in consequence, 

 the name insoliUi falls in the svnonvmv uikUt /'. (Icsctiic.
