shorter. The himina in Huphina pitys is elongated and cord- 

 ate, the sides tapering more abruptly than in the last species. 

 The disc is small and circular, looking dark fi'om the enclosed 

 chitinous tubing. On the hindwing the special scales are 

 similar, but broader at the base. The plume-scales in H. wal- 

 laceana ai'e obclavate, less broad at the base than in the two 

 preceding species, and tapering much more gradually. //. 

 qicacb'icolor has plume-scales of much the same character, but 

 a little smaller. In 77. agnata we meet with a scale which 

 may be called triangular with elongated apex. The disc, as 

 before, is small. 



The scent-scales in Ilujyhina nerissa are extremely abundant, 

 apparently outnumbering those of the ordinary form. The 

 laminae are very long, obclavate, tapering gradually up to 

 the distal extremity ; the disc is small and circular. In 77. lea, 

 again, the scent-scales appear to preponderate over the others. 

 They are slightly shorter than in 77. nerissa, and the lamina is 

 a little broader at the base ; hence the tapering is more abrupt 

 than in that species. The condition in H. nadina is much 

 the same, the scent-scales being very numerous, with laminae 

 shaped like an elongated racquet. They are, however, some- 

 what shorter than is usual in this genus. 



The scent-scales in Hwphma naomi and 77. judith resemble 

 those in H. lea ; the scales from the hindwing being generally, 

 though not invariably, a little shorter and broader than 

 those from the forewing. In 77. olga and 77. aspasia they 

 are enormously long on the forewing, tapering gradually to 

 the apex from a rounded b.ise ; on the hindwing they tend, 

 as before, to somewhat greater breadth and shortness. The 

 disc in these species, though still small, is larger than in the 

 otherwise similar forms of Pieris. 



Huphina periclea, H. scyllara, II. retnha, 77. andersonii, 

 II. Julia and 77. eperia form a group in which the scent-scales 

 all display, in slightly varying amount, an elongated pyriform 

 outline like that seen in H. boisduvaliana and H. pitys. The 

 scent-scales in 77. abnormis are exceptional in the genus, being 

 relatively very small, with the laminae laterally compressed, 

 and not tapering to a point. They have, however, the rounded 

 base and small circular disc characteristic of Huphina.
