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

 afternoon : a $ 2'criafi cutcrpc, 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 Bryophyllum : it was, how- 



ever but ill-concealed thereby. 



(2) On a po/c green leaf. 



(oj On a yellowish-green, finely-cut fern {Adiantum sp.). 

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

 Ipomcea). 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 Bryophyllum. 

 Same place and day. A ^ of 7". euterpe was seen to settle 

 three times : — 



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



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



what cryptic. 

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

 result less cryptic. 

 Mackfield, Jamaica, 81 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 Bo-yophyllum. 



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



leaves of Bryojyhyllum. 



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



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

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

 one other time it was well concealed, but the plant 

 not noted ; on two occasions it Avas 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-win<irs.
