This species is allied to H. theiv or a, "Wat., but at once distinguished 

 by the erect, very little curved scutellar horn ; in the female of theivora 

 it is strongly curved. Mr. "Waterhouse says that the colour of theivora 

 is black, without mentioning anything more on the abdomen. But, 

 judging from the figure, it seems possible that the abdomen has nearly 

 the same colour as in febriculosa. 



The genus Helopeltis is much in need of a revision, most of the 

 species being very imperfectly characterized. The figures of the 

 scutellar horns in Mr. Waterhouse's paper are useful, but the expla- 

 nation of the plate is not identical with the references given in the 

 text, and the coloured figures do not at all correspond with the de- 

 scriptions. In almost all specimens of Helopeltis which have reached 

 European collections, the fourth antennal joint seems to have been 

 broken off. From Prof. Costa's figure of H. podagrica it is evident, 

 however, that the fourth joint is very long, so that the antennae have 

 nearly thrice the length of the body. 



As the Indian readers of this Journal may often meet with species 

 of Helopeltis, and as these insects are of a certain economic interest, 

 I think it will be of use to publish here a list, with references, of the 

 hitherto described species. The following is a chronological list. For 

 information about the general habits of the tea bugs I refer to the 

 work of Mr. J. Wood-Mason.*
