282 Mr. A. R. Wallace's Notes 



Beneath; the upper part of the transverse band almost 

 obsolete, the costal margin from its extremity to the 

 apex, whitish; the third and fourth spots from the outer 

 angle of the anterior wings much smaller than the rest ; 

 other differences as above. Rather smaller than the 

 females of D. Pandarus. 



Hah. — Bourn (Wallace). 



If we are to discriminate local forms with a view to 

 the investigation of their true place in nature, such slight 

 but definite modifications as this insect presents must be 

 recognized by giving it a distinct specific name. 



7. DiADEMA Saundeesi, n. 3. 



Male. Form and size of D. Pandarus. 



Above ; black, richly glossed with blue in some~places; 

 anterior wings with a transverse white band, as in D. 

 Hewitsoni, but broader, edged with violet and with a 

 faint violet gloss, the lower spot of this band small and 

 detached; the rufous-orange band as in D. Hewitsoni, 

 but broader, more richly coloured, and continued on to 

 the anterior wings so as almost to meet the white band ; 

 the row of black spots larger and more regular, but not 

 pupillate ; the submarginal row of blue marks wanting. 



Beneath ; differs from D. Hewitsoni by the shorter and 

 whiter transverse band, and the rufous patch with two 

 black pupillate spots at the outer angle of the anterior 

 wings ; on the posterior wings there is a whitish patch 

 near the base, and the row of pupillate spots are only 

 edged with rufous, and are placed on a dusky ground^ 

 bounded above and below by a wavy white line. 



Hah.— Timor (Coll. Wallace, B. M.). 



This fine species is intermediate between D. Pandarus 

 and D. Hewitsoni.

The underside of these insects corresponds closely with 

 the upper side, as figured by Mr. Hewitson.
