NOTES ON BUTTERFLIES FROM THE NAGA BILLS. o05 



Abrota ganga, Moore. 



A single female was taken by Capt. Porter on the Dihang Eiver, Abor 

 Hills, in July, which differs from Bingham's description and figure and from 

 Seitz's figure in having all the pale markings more suffused with dusky 

 green, with the exception of the discal band on the hindwing which is 

 almost white and very narrow. 



Symph^dra dirtea, Fabr. 



Three forms of dirtea occur in Manipur and one m the Naga Hills, viz. 

 typical dirtea, Fabr. Occurs at Sebong, Eastern Manipur Hills, where 

 several specimens were taken from March to July. 



Var. intermedia, n. v. is an intermediate form connecting dirtea and 

 Masiana. Many specimens were taken at Sebong, Eastern Manipur Hills, 

 on the Irang Eiver, Western Manipur Hills, and at Nichuguard, Naga Hills, 

 from March to October. 



Var. kJiasiana, Swinhoe : typical specimens were taken on the Irang 

 River, Western Manipur Hills and near Sebong, Eastern Manipur Hills, in 

 March and April, and again in October. 



I do not think the difference in facies is due to seasonal causes as all 

 three forms fly together on the Eastern Manipur Hills and varieties inter- 

 media and khasiana fly together on the Cachar Eoad, Western Manipur 

 Hills. In the Naga Hills var. intermedia only was met with. 



DOPHLA DUKGA SPLENDENS, Sub.-sp. nOV. 



A single male taken near the foot of the Hills on the Ukral Road, about 

 28 miles east of Imphal, in July at about 3,000' dift'ers considerably from 

 typical forms I have in my collection from Sikkim and the Abor Hills. 



Upperside : white discal band on both wings broader ; forewing otherwise 

 similar. 



Hindwing : the black margin to both edges of the white discal band 

 broader and more distinct : the blue border beyond outer edge of discal 

 band composed of a complete series of well marked lunides with the outer 

 edge well defined ; in typical durga from Sikkim and Assam this blue band 

 is only formed into distinct lunules near the costal end; the tornal half 

 always having the outer edge even and rather diffuse ; terminal detached 

 blue lunular streaks very distinct. Underside : basal ground colour purer 

 blue and not so tinged with green ; all the markings broader and more 

 distinct ; the subterminal area marked with large black lunules which are 

 towards the apex of both wings very markedly outwardly pointed ; ter- 

 minal bluish white patches more prominent. Somewhat larger than typical 

 forms before me. 



Expanse : S 4-52'. 



This appears to be a very distint race of D. durga. 



DoPHLA CXTRVIFASCIA, n. sp. (PI. II, Fig. 13). 



Male and female. Upperside : bronzy olive green somewhat similar to that 

 of B. nara, but of a much more bronzy tint. Forewing : apex acute ; 

 termen nearly straight; cell with a medial and apical pair of short trans- 

 verse black sinuous lines, the former extending into interspace 1 forming a 

 circle and a black dot below ; the space between the two pairs of dark 

 lines paler than the ground colour ; a postdiscal transverse band of spots as 

 in T>. sahadeva but much smaller ; the spots in interspaces 2 and 3 sullied 

 with the ground colour ; a preapical pair of pale almost white spots in 

 interspaces 6 and 8 below which is a pale yellowish green area, commencing 

 in a point in interspace 5 and ending on the dorsum filling the outer half of 

 interspace 1 and inwardly broadly bordered with dark blackish green ; a
