the female has minute scale-hke rudhnents of organs of flight, the mctano- 

 tmn proper about equal to the medial segment, and the hinder extremity of 

 the sixth ventral segment of the abdomen unarmed. In Phib. virgea $ , 

 as I have already pointed out (P. A. S. B., July 1877), the metathoracic 

 and mesothoracic tubercles figured by Wesfcvvood are exceedingly minute 

 rudiments of organs of flight ; and the same relation of length subsisting 

 between the two divisions of the metathorax in JPJiib. acanthopus and Phih. 

 Annamdlayanum obtains in it {Phih. virgea, the male of which we know 

 to be a wingless insect or practically so), I expect that the males of these 

 two species with also prove to be apterous ; in which event, then the winged 

 male ascribed to P. accmtliopus by De Haan, and by Westwood following 

 him, will belong to another species. 



With the single exception of LoncTiodes hrevipes, this is the only spe- 

 cies of PliasmidcB at present known to us from the Malabar Coast and from 

 the hill-tops of Southern India !

I have examined with Professor Westwood the typical specimens of 

 P. Cantori preserved in the Hopeian collection at Oxford and I find that 

 the insects have been legitimately united by their describer ; the female hav- 

 ing small equal blunt representatives of the conspicuous cephalic tubercles 

 seen in the male ; these tubercles not having been represented by Professor 

 Westwood in his figure of the former, I was led to suggest {Joe. supra, cif.) 

 that P. Westiooodi, which had cephalic tubercles, and those of unequal size, 

 might be the opposite sex of P. Cantori S , the true female of which had 

 been represented as having none. These tubercles are in P. Cantori placed 

 further forwards on the disk of the head than in the present species.

In J. A. S. B., Vol. XLIV, Part II, 1875, p. 217, 1 have described a 

 remarkable insect, obtained by my native collector at Johore, as the female 

 of Westwood' s Necroscia Tolas, and pointed out the very close relationship 

 of this species to Lopaplms bracliypterus, Loncliodes porus, L. Bootanicus, 

 and Bacteria Baucis, all of which should find a place in the same genus 

 with it. 



M. C. Stal has described the same insect from a Malaccan specimen 

 under the name Candaules Sparnius.
