NYMPH ALINiE. 287 



$ All white marki7igs larger. Fore-ioing : central bar touches 

 small spot near base, reacliing inwardly to origin of first median 

 nervule, and outwardly to a little beyond lower part of extremity of 

 discoidal cell. Hind-iving : white patch very much larger, extending 

 so far beyond middle as to leave only a moderately broad hind-marginal 

 border of black (of almost even width throughout). Edges of larger 

 markings (especially of central bar of fore-wing) glossed with violaceous- 

 blue as in U. Anthedon. Under side. — As in ^, but white mark- 

 ings much enlarged, especially in hind-wing, which is all white except 

 for a costal and a hind-marginal border of brown. 



This Euralia presents an unmistakable mimicry of Amauris 

 Ochlea (Boisd.), a local species inhabiting the coast of Natal and St. 

 Lucia Bay. All the white markings in the Euralia are in proportion 

 smaller than in the Amauris, and the central bar of the fore-wings is 

 more obliquely placed ; while on the under side the grey colouring is 

 paler and the hind-wings want the narrower basal black of Ochlea, and 

 present a pale ray (from the central patch to the apex) which is not 

 found in the latter. 



E. DeceptoT is intermediate in character between E. mima and 

 E. Wahlhergi, but is on the whole perhaps nearer to the former, both 

 in size and markings ; though the absence of any ochreous tinge in 

 the white bars and the pinkish gloss of those markings, added to the 

 width of the central bar of the fore-wings, approximate the insect to 

 the latter. The white spots of the head, palpi, and back of thorax 

 are identical in the three species, and a tuft of ochreous hairs on the 

 posterior region of the breast is also found in all of them. 



The first example (a c? ) of this interesting Diadema known to nie was 

 taken by Mr. W. Morant in a road cut through thick bush, in Victoria 

 County, Natal, about the middle of July. In reply to an inquiry from me, 

 that gentleman states that the place of capture was one in whicli he had some- 

 times found Danais Ochlea. 



The only other specimen I have seen was captured by Colonel Bowker at 

 Clairmont, near D'Urban, on 2d February 1880. This is the $ figured on 

 Plate VI. Colonel Bowker wrote at the time that it was quite a cliance 

 capture, having been started by his walking among some low branches and 

 leaves by the side of a bush-road.^

^ Since the above was written, I have seen a second $ , from the collection of Mr. H. 

 Grose Smith, taken at Delagoa Bay by Mrs. Monteiro. This individual differs slightly on 

 the upper side from Mr. Morant's example, having the central bar of the fore-wing narrower 

 in its lower and larger portion, not rising at all above second median nervule, and extending 

 only a very little below first median nervule.
