Constant Spring, Jamaica, 4 January, 1907. A dull 

 afternoon : a $ Terias cutcrpe, Men., was seen to 

 settle close to a leaf of its own size, shape and colour. 



Same place and day. A ^ T. euterpe was watched for 

 some time and repeatedly disturbed ; it seemed to 

 avoid dark green foliage, and always settled on a low 

 plant with yellow-green leaves. 



Mackfield, Jamaica, 27 January 1907 ; 4.30 p.m. A 

 specimen of T. euterpe seen to settle four times as 

 follows : — 



(1) On a yellowish leaf of Bryopihyllum : it was, how- 



ever but ill-concealed thereby. 



(2) On a pale green leaf. 



(3j On a yellowish-green, finely-cut fern (Adiantum sp.), 



(4) On a yellow-green leaf of a Convolvulus (or perhaps 



Ijwmcea). In this case the concealment of the 



insect was remarkable. 



Same place and day. Another specimen of T. euterpe was 



seen to settle on the under side of a yellowish leaf of 



the Bryophylhim. 



Same place and day. A% oi T. euterpe was seen to settle 



three times : — 

 . (1) On a yellow leaf of Bryophylktm ; fairly cryptic. 



(2) On a light green leaf of an unknown plant, some- 



what cryptic. 



(3) On a leaf of Bryophyllum less yellow than (1), the 



result less cryptic. 

 Mackfield, Jamaica, 31 January, 1907. Three specimens 

 of T. euterpe (sex not determined and specimens not 

 preserved) were watched with the following results 

 respectively : — 



(1) Seen to settle on a yellow leaf oi Bryophyllutii. 



(2) Seen to settle three times, twice being on yellow 



leaves of Bryophyllum. 



(3) Seen to settle seven times. Twice on yellow leaves 



of Bryop)liylhim (in one case it was very well con- 

 cealed) ; twice on a yellow fern (? Folypodium sp.); 

 one other time it was well concealed, but the plant 

 not noted ; on two occasions it was less well 

 concealed. 

 Constant Spring, Jamaica, 1 January, 1907. A $ of 

 Terias (? elathea, Cram.) was seen to settle in the 

 shade on a leaf of the same colour as the under-side 

 of its hind-wiu2fs.
