4. Pieris notistriga. 



Pieris notistriga, Butl. & Druce, Cist. Ent. i. p. Ill a ; P. Z. S. 3874, p. 361 \ 



Alis albidis, anticis costa, decrescente in medio, apice et margine externo introrsum valde sinuato et posticis 

 margine externo nigro-fuscis : subtus fere ut supra, sed anticis interdum punctis submarginalibus quinque 

 albis notatis ; posticis linea longitudinali per cellulam ad apicem extensa fusca, bine in margine externo 

 fusco fascia (interdum maculosa) ferruginea includente, posticis et anticarum basi flavo tinctis. 



2 mari similis, sed alis flavescentibus et colore fusco latiore ; anticis linea a cellulse fine ad marginem externum, 

 in margine interno et posticis linea subcostali quoque fuscis : subtus fere ut supra.

This species is a very variable one both as to size and markings, especially of the 

 front wings, and this applies to both sexes. The dark basal portion of the costa of the 

 primaries, in most cases, is only connected with the dark apex by the dark costa, but 

 in some instances there is an evanescent transverse band passing through the end of the 

 cell towards the chief inner prominence of the dark outer margin. There is thus a 

 tendency to cut off a subapical elongated white spot from the rest of the wing. This 

 transverse band in the males is never quite complete, and sometimes appears as a small 

 spot at the end of the cell ; in some females, however, it is well defined and complete, 

 and when in this state the female is hardly distinguishable from that sex of P. pisonis. 

 Regarding the dark subcostal band of the secondaries beneath, upon which the distinction 

 between P. notistriga and P. pandosia was based, we find that it is almost universally 

 present in the former, but in certain examples, chiefly from Mirandilla in Guatemala, 

 it is either absent or evanescent, and this being the case we are not sure that the 

 distinction between these two forms can always be traced. Fresh females have a distinct 

 yellow tinge over the lighter portion of the wings, but we believe this colour fades in 

 specimens that have been exposed to light for some time. 



P. notistriga, though widely distributed, does not seem to be a very common species ; 

 nevertheless we have a good series of examples from Guatemala and the State of 

 Panama. It is found in the hottest region up to an elevation of about 2000 feet.

Alis cretaceo-albis, anticis limbo costali angustissime, et margine externo anguste introrsum profunde serrate 

 fuscis : subtus anticis albescentibus, costa anguste apice et posticis omnino ochraceo tinctis, illis nonnunquam 

 pallide fusco indistincte marmoratis. 



£ mari similis, sed anticis macula ad cellulae finem fusca, marginibus fuscis latioribus, et posticis limbo externo 

 colore eodem maculatis (alis ambabus interdum ochracescentibus, interdum fuscescentibus).
