The colours of the insect green-blue, brown-red and Venetian red, and black. 



Figs. 29, 30, two dissimilar red scales from the posterior wings. 



,, 31, 32, blue green, near the base of the anterior wing ; 32 is foreshortened. 



,, 33, from the same position, blue green, 



„ 34, to 36, black. 



„ 37, 38, red. 



,, 39, a basal red hair scale ; 40, 41, from the same position, but black. 



,, 42, dentate scale, orange, from the abdomen, some of this class have 4 longer or 6 broader dentations. 



,, 43, 44, black thoracic scales ; but many are like No. 39. 



,, 45, to 47, green blue, delicately striated ; striae duplicated, with alternate dotted lines. 



,, 48, short hair-like blue scale, from near the abdominal margin. 



,, 49, to 52, red discal scales. 



, , 53, 54, orange scales from the abdomen. 



Mr. Joseph Beck, in 1879 examined a large number of the scales of Lepidoptera, and he stated that he found 

 invariably that the striae (which he called corrugations) were situated only on the underside of the scale, or that nearest 

 to the body of the insect. Nothwithstanding this statement, I have seen what appears to me unmistakable evidence 

 that some of the darker scales of the Ornithoptera are striated on both surfaces. If so, then the longitudinal lines 

 cannot be corrugations or folds of the membrane. Certainly it would be possible, but not probable.
