for some considerable distance. The true character o£ the glassy portion 

 can be seen only after carefully dissolving off the outer waxen layer with 

 xylol. 



Length 1-25-2-50 mm. 



Male, second stage. — Ellipsoidal ; margin with a series of rather widely 

 separated, large spines, o£ which there are 16-17 on either side ; besides 

 these there is also one additional submarginal spine in each of the stigmatic 

 areas. Antennae of six segments, of which the third is about equal in 

 length to the 4th, 5th and 6th together. Legs normal. Angles of posterior 

 cleft each with two long hairs.

This species is remarkable for the very singular character of the male 

 puparium, which in its external form bears a striking resemblance to small 

 examples of Dactyloinus nipce^ Mask. ; so much so, that they were mistaken 

 for examples of this or an allied species, before the microscopical prepa- 

 rations were made. The male puparium of the, hitherto, only other known 

 species of Ceroplastes * is of the typical Lecaniid form, and without any 

 flocculent or opaque waxy appendages t of any kind. It may be necessary 

 at some future date to raise C. singularis to subgeneric rank, though in the 

 light of our present knowledge, and in the absence of a larger series of the 

 adult females, such a course would at the present moment be inadvisable. 



. Another remarkable feature regarding the male puparia is that they 

 occurred in enormous numbers on the under surface of the leaves of the 

 food-plant, presenting a very striking appearance. It is interesting to add 

 also that a very large percentage were parasitized by a small Chalcidid 

 insect, but unfortunately pupae only were found. A few of the puparia 

 also contained pupae of the Ceroplastes, but these did not afford any morpho- 

 logical characters of note. 



Chavannes + has described a Ceroplastes from Psidlnm sp. ; but, so far as 

 one can gather, this species is distinguishable by the marked character of 

 the waxen test or puparium of the female. The male or its puparium is 

 not described. 



A few examples of Aspidiotus cyanopliylli. Sign., were found in asso- 

 ciation with C singulayns.

 t The male puparia of the Ceroplastes, no. 1326 (see p. 192), is of a similar character, but 

 there is no flocculent matter present.
