238 J. Wood-Mason — Synopsis of the Species of Chocradodis. [No. 3, 



XI. — Revised Synopsis of the Species of Chooradodis, a remarkable Genus 

 of Mantodea common to India and Tropical America. — By J. Wood- 

 Mason, Officiating Superintendent of the Indian Museum, and Pro- 

 fessor of Comparative Anatomy in the Medical College, Calcutta. 



(With 15 Woodcuts.) 

 Since the former version of this Synopsis was published, some 

 additional material has fallen into my hands, by the aid of which I have 

 been enabled to establish the existence of two distinct Indian species, 

 and to identify with certainty a larva which I had previously assigned 

 with hesitation to Ch. rhomhicollis. 



Two Indian species have been described, one by Fabricius under 

 the name of Mantis cancellata, and the other by De Saussure as Ch. 

 squilla from a perfect male insect and a larva. The recent discovery of 

 the true female of the latter proves that the insects I had previously 

 considered to be females and abnormal males of it represent a different 

 species, to which I have the less hesitation in applying the Fabrician 

 name that Prof. Westwood has named a female from Saugor in the 

 Oxford Museum Ch. cancellata. 



De Saussure has described and figured one of the remarkable larvae 

 of the genus — that of his Ch. squilia — , and pointed out the close resem- 

 blance it bears to that of an American species ; De Borre has recently 

 figured a larva of Ch. rhomhicollis which is nearly intermediate in age 

 between my figures 3 and 4 ; a larva of Ch. rhomhoidea is preserved in 

 the British Museum ; and I give figures of the larvae of three additional 

 species and also of an earlier stage of Ch. squilla ; so that, counting the 

 larva of Ch. strumaria figured by Merian, larv« of no less than 7 out of 

 the 9 species recognized by me are now known.

The close similarity of these larvae to one another furnishes a 

 remarkable confirmation of the view that the adults are couofeneric.
