Mr. A. G. Butler on Lepidoptera 



centrum gives off rays on one side only and on the other side 

 receives rays only. It then, when isolated, much resembles 



the stellates of Holasterella, Carter, 



/ ■ 



The accompanying rough sketch, made by camera lucida, 

 illustrates this mode of union. In some parts of the section, 

 marked o, the razor has cut away the centrum of a corpuscle, 

 leaving, however, the spines, which thus remain to indicate 

 its position. As the specimen from which the section was 

 taken had been boiled in caustic potash, the rays of the 

 corpuscles shown in the figure are not so long as in untreated 

 specimens ; in my extended paper careful drawings will show 

 the rays complete up to their natural terminations. 



XXI. — Lepid<>2<t< ra collected by Mr. C. M. Woodford in the 

 EUice and Gilbert Islands. By ARTHUR G. BUTLER, 

 F.L.S., F.Z.S., &c. 



The species here enumerated were obtained in Nukufetau 

 (Ellice group), and Tarawa and Tapetewea (Gilbert group). 

 They are chiefly interesting as adding to our knowledge of 

 the fauna of these islands.
