COLLECTION FROM CHRISTMAS ISLAND. 



523 



Terias amplexa, sp. n. 



Perhaps nearest to T. clesjardinsi of Madagascar, but very dis- 

 tinct from all described species ; wings above bright gamboge or 

 lemon-yellow ; primaries with black costal margin and a perfectly 

 regular, rather narrow, external border of almost equal width 

 throughout and regularly sinuated between each pair of nervures ; 

 secondaries with a narrower border formed by the union of a series 



o. 



Terias amplexa. 



of marginal spots, the inner edges of which are bracket-shaped, 

 - — ' — .. Body quite normal ; under surface bright sulphur-yellow, 

 with marginal black dots and indistinct brown markings, as in T. 

 hecabeoides ; no subapical brown patch on the primaries as in T. 

 desjardinsi. Expanse of wings 42 millim. 



One male example. 



In colouring this species corresponds better with T. moorei from 

 Camorta than with T. desjardinsi ; but the regularity of the border 

 to the primaries separates it at a glance from all the described forms 

 of this group. 



The Moth is much injured ; it is a small insect approaching 

 Pyralis miseralis, Walk., but is too much broken and rubbed to 

 enable one to say whether or not it is an undescribed species. 



VIII. ECUINODERMATA. 



By F. J. Bell. 



The Echinodcrms are common Indo- Pacific species : viz. Linckia 

 diplax (M. Tr.), Opiiiocoma cethiops (Ltk.), Ophiocoma scolopen- 

 drina (Ag.), Actinopyga miliaris. A specimen of Actinometra is 

 unfortunately too much injured to allow of description, but undoubt- 

 edly belongs to an undescribed species, distinguished by the large 

 number of cirri ; cirri, as a rule, being numerous in Antedon and 

 scanty in Actinometra.
