V. HlERODULA COARCTATA, SauSS. 



H. coarctata, de Saussure in Bull. Ent. Suisse, III., 1869, p. 67, 9 ; Bolivar, op. at., 

 p. 311, # ; Kirby, Cat. Orthopt., I., 1904, p. 245. 



Two females from Ramanad. Immature specimens were common in August on 

 bushes of Cassia auriculata at Mandapam. 



Specimens have been recorded from Australia, but it is a little doubtful whether they 

 really belong to the same species. The true H. coarctata is common in all the more sandy 

 parts of India, from Sind to Bengal and Cape Comorin. Some of the specimens in the 

 Indian Museum have been identified by de Saussure. 



The flowers of Cassia auriculata are by far the most conspicuous objects in the sandy 

 wastes of Ramanad, and there can be no doubt that the Mantis benefits as regards its 

 food by haunting their vicinity. Cf. pp. 185-186, antea. 



No specimens of the Phasmidse or the Earwigs were seen in Ramanad. 



VI. Epacromia tamulus (Fabr.) 

 Common together with the succeeding species. A widely distributed form in India. 



VII. Chrotogonus oxypterus (Blanch.) 



Ch. oxypterus, Bolivar, op. cit., p. 605. 



This species is very common on sand, but not on the seashore. Although it 

 exhibits considerable variation as regards the minute details of its coloration, it is 

 always most inconspicuous when resting on a sandy soil, especially in the shade of the 

 wiry grasses and thorns which are produced by such a soil. As a rule, the first indication 

 of its presence is given, at any rate to a human eye, by the movement of its leap, which 

 is very long for the size of the insect. 



I think that I am right in the identification, Ch. oxypterus, judging from Bolivar's 

 remarks, appears to be the common one in Madura, but the species are difficult to 

 distinguish except by comparison, and Ch. trachypterus is the only form authentically named 

 that I have been able to examine. 



VIII. Atractomorpha crenulata (Fabr.). 

 Not uncommon at Ramanad among low vegetation. 



IX. Acridium aeruginosum, Burm. 



A. aeruginosum, Cotes, Ind. Mus. Notes III., 1898, p. 21. 



According to Cotes, this Locust is very variable in colour and sometimes becomes 

 destructive on account of its numbers in Madras. I only saw a few specimens, all of which 

 were veryismall and pale in colour.
