P. marsena Hew. (= ornata Fldr., <$ — aitchisoni W .-Mas.) (171 li). Above blackish-brown, of the small marsena. 
white hyaline spots a double, rather large one is in the cell. Body and proximal portion of the wing dark, with 
hair of a somewhat greenish reflection. Under sin face yellowish red-brown with a few small silvery yellow 
splashes scattered across the wing. Indo-China, Java, Sumatra, Borneo. 
P. murdava Mr. (171 li) is quite similar, only the spots in the cell are smaller, the hindwing beneath murdavc. 
has fewer splashes, but a submarginal row (particularly distinct in the §) of yellowish, spot-shaped brightenings. 
Sikkim, Assam, Borneo. 
P. stramineipennis W -Mas. This species reaching the paleartic region in West China has been over- straminei- 
looked. in the 1 st Part. It has theshape and marking of the preceding ones, but the double spot in the cell of pcnnis. 
the forewing is effaced, whereas the hair of the proximal half of the wing is of a bright yellowish-grey. Sikkim, 
Bhutan, West China, Assam. 
47. Genus: l*lnstmg»ia Btlr. 
This genus above all differs from Pithauria in the very much longer antennae almost attaining the length 
of those of the following genus. (Pirdana) which is uncommon in the Hesperidae. Nearly all the species are 
of the same size and very similar wing-contours, mostly with a rather variegatedly spotted under suiface, and 
some exhibit the yellow colour being common in other genera ( Padraona , Telicota, Erinnys etc.), so that the 
insects are difficult to discover from amongst the great number of those lepidoptera swarming around every 
blossoming bush. But they are considerably rarer than most of the Padraona etc. More than a dozen of species 
are known. 
P. pugnansAic. (175 a) still shows quite the same shape of the preceding genus and thereby al*o such a pugnans. 
great resemblance to Parnara that it has been placed to this genus. But the arrangement of the small hyaline 
spots in the forewing is not that of Parnara. The lower cellular spot is situate at the lower cell-wall, and below 
it there is a rather large, almost rectangular transverse spot. The hindwing is on both sides spotless dark 
brown, but above the hair in the proximal portion of the wing is somewhat lighter glossy. Malacca, Sumatra. 
P. tessellata Hew. (= eulepis Fldr.) (174 a). Arrangement of the hyaline spots of the forewing similar tessellata. 
as in pugnans, but the lower cellular spot is very small. Quite different beneath, being dark brown speckled 
with numerous white splashes, like the apex of the forewing. From Celebes, apparently distributed over the 
whole island and not rare, besides in Malacca, Borneo. — mangolina Fruhst., from the Sula Is., is at least a mangolina. 
third smaller than the Celebic form, but it shows larger hyaline spots; the splashes beneath are more yellow 
than white. — In palawata Stgr. the splashes beneath are also bluish-white instead of yellow; it was regarded palawata. 
as the Palawan-form of tessellata , but Piepers states that it flies in Java together with yellow specimens. — 
Larva greyish-blue, head with black sides; on sugar-palms (Arenga). 
P. naga Nic. (174 a) is a species hardly separable from the preceding ones. Above almost exactly like naga. 
tessellata, beneath the hindwing is somewhat more scantily spotted, representing the jnreceding species in Assam, 
Pegu. - pellonia Fruhst. (174 a) and its eastern form vakflia Fruhst. (174 a) represent the species in Java, but pellonia. 
hardly differ from Indian specimens: valenia is perhaps somewhat smaller, at the costal margin of the forewing valenki. 
of a duller yellowish-grey, the apex of the forewing beneath more spotted, pellonia is somewhat larger and 
more intensely coloured; with a distinct yellow hue of the costal margin and above the hind-margin of the 
forewing. Hindwing predominantly hued with yellowish-green, in the $ even honey-coloured. The square 
spots on the hindwing beneath are white in the <$, yellow in the $. Specimens that correspond well with this 
description are before me from Borneo. 
P. telesinus Mob. (174 a). The spots are grouped on the black forewing above in the shape of shortened telesinus. 
median bands which are dull orange in the <$, very pale ochreous in the $; thereby the colour ing is very similar 
to that of some Telicota. Under surface deep yellowish-brown, without square spots of the hindwing in the 
disc of which there are only traces of the small central hyaline spots. From the Philippines. 
P. similis Elio. & Edw. (174 b) above almost exactly looks like telesinus, but on the hindwing beneath similis. 
it has rows of blackish spots. Pulo Laut. 
P. noemi Nic. is quite similar, hut considerably larger, the uppermost of the cellular spots is oblong, noemi. 
as large as the spot behind it, in the basal half of the costal area there is, instead of the hardly traceable 
yellowish hue, a thick yellow stripe. Sikkim. 
P. corissa Hew. ( — drancus Ploiz (174 b). Upper suiface black, wedges along the costal margin, above corissa. 
the hind-margin of the forewing, and through the cell of the hindwing as well as the fringes golden yellow. 
In the forewing 3 central hyaline spots and 1 subapical one. Under surface quite lioney-colourecl, only the 
hindmarginal portion of the forewing black, pierced by the hyaline spots. Borneo, Pulo-Laut. — illdrasana indrasana. 
Elw. & Nic. is the continental form described from Tavoy, but also similarly found by Martin in Sumatra,
