Targioui-Tozzetti. " One such species," he says, " was latelj'' 

 described in this work under the name of Coccus stelUfer, and we 

 are now enabled to figure another species, for a knowledge of 

 which we are indebted to Mr. F. W. Burbidge, of the Botanical 

 G-arden of Trinity College, Dublin, by whom it was found in the 

 Orchid-house, especially affecting the Ladyslippers (Cypri- 

 pediums), but also occurring sparingly on Sobralias, Cattleyas, 

 and Dendrobiums. Our engraving (fig. 131) represents two small 

 leaves of a Cypripedium, showing that it is chiefly the plain under- 

 side, and not the spotted upperside of the leaves, that the insects 

 attack, forming small groups. The natural size of the full-grown 

 insects is shown upon the leaves (figs. 1, 2), and the magnified 

 insect is seen at fig. 3, with a small portion of the waxy marginal 

 scales at fig. 4. It will be seen from fig. 3 that all traces of 

 articulation in the body are lost, and that the fimbriated margin 

 is more or less incomplete in parts, and not so continuous as 



shown in fig. 4 Fig. 5 represents the underside of a young 



specimen of one of the insects, copied from Dr. Siguoret's plates, 

 showing the articulation of the body, and the three pairs of 

 iointed legs, which are gradually absorbed and lost alter the 

 insect has become affixed as a scale upon the surface of the leaf. 

 The species may be termed Asterolecanium orcliidearum, J. O. W. 

 It closely resembles A. bambuscv, Sign. *, which is parasitic on 

 the bamboo, but the scaly fimbriation is longer than in that 

 species, the habitat also indicating it as distinct. The males of 

 none of the species of the genus have yet been observed." 



The insect under investigation was found to agree with the 

 descriptions of Ceratapliis latanice (see next page); and to be 

 quite certain that the Cambridge species was the same as the 

 one Westwood had received from Dublin in 1879, I wrote to 

 Mr. Burbidge at the Trinity College Botanic Grarden, who very 

 kindly sent me some specimens : these proved to be identical 

 with the species found in Cambridge. Mr. E. Newstead, to 

 whom specimens were submitted, confirmed the identification 

 of the insect as Geratapliis latanice. Professor Poulton has 

 not been able to find any type of A. orcliidearum in the Museum 

 at Oxford. 



Westwood's name of Asterolecankcm orcliidearum has never 

 appeared in the 'Zoological Record,' or other lists, doubtless
