Phyllium Donovani, Donovan, Ins. Ind. pi. 11, fig. superior. 

 G. R. Gray, Syn.Phasm. p. 31 ; and in Zoologist, i. 120. 

 Hab. " One of the islands of the Indian Seas." 



I feel satisfied, from an attentive examination of the de- 

 velopment of the tegmina and wings in the two sexes of 

 this genus, that Donovan's figure above referred to, not- 

 withstanding the minute size (probably inaccurate) of the 

 autennse, is intended for the pupa of a male insect, and 

 not that of a female, as suggested by Mr. G. R. Gray. 

 Without a more precise knowledge of its locality, it seems 

 scarcely possible to identify it with the perfect insect, of 

 which it is in so immature a condition.

Phyllium crurifolium, Serville, H. N. Orth. p. 291. 



Be Haan, Orth. Orient, p. 112. 



G. R. Gray in Zoologist, 1843, i. 120. 

 Hab. In India orientali (Serville) ; Borneo {Be Haan) ;

The Hopeian Museum possesses two of the supposed 

 males of this species : one from the Collection of M. Mar- 

 chal, named by Serville, with "Seychelles" indicated as the 

 habitat, in the handwriting of Latreille ; and the other, 

 which I obtained from the Collection of Serville itself. I 

 can discover no difference between these two specimens and 

 the typical specimen of the male of Phyllium, bioculatum, as 

 represented from my drawing in Griffith' s Animal Kingdom, 

 both exhibiting traces of the two spots on the inner mar- 

 gin of the fore femora, notwithstanding Serville, in a note, 

 implies the want of these two marks, and consequently 

 thereupon maintains the distinction of the two species. It 

 is proper to observe also, that the margin of the basal half 

 of the outer lobe of the fore femora exhibits traces of the 

 three minute denticles which exist in the same part of the 

 male of Ph. bioculatum. The Hopeian Collection also 

 possesses several females of this species, also labelled from 

 the Seychelles and East Indies, from the Collections of Mar- 

 chal and Serville, which agree with the description given by 

 Serville.
