REPORT UPON TWO COLLECTIONH OF MYnrnpODA. 1^9 



the absence of sulci on the stcrnites, and by the fact that the anal 

 pleura is terminated by two spines, one inferior and large, the 

 other at some distance above it and smaller. 



Ceylon : Mr. Green brought back one fem-ale specimen measuring 

 about 90 mm. (3^ inches) in length. 



Heterostoma friste, Meinert. 



Meinert, Vid. Medd. Nat. Foren. (Copenhagen), 188(), pp. 114, 115 ; 

 Haasc, op. cit., pp. 91, 92. 



This is the species that I previously (Ann. Nat. His., 1890, p. 245) 

 referred to as the $ oiS.spinosiim. Mr. Thurston has sent one speci- 

 men from Madras, another from the Nilghiri Hills, and a third from 

 Mysore. Dr. Meinert's specimens were from Vellore and the 

 Sheveroy Hills. 



In this species the anal femur is armed v\^ith 7 or 8 strong 

 spines ; the anal pleura terminates with two spines, one above, 

 smaller and at some distance from the other, there is a conspicuous 

 lateral spine and sometimes also a superior spine ; the sternal sulci are 

 conspicuous although posteriorly abbreviated. In the 6 the tarsal 

 segments of the anal leg are thickened and compressed. 



The 9 of this species bears a strong resemblance to the 9 of the 

 Ceylonese species paucispinosum. It may, however, be recognised 

 by the absence of sternal sulci. 



Dr. Haase regards tristc only as a variety of the Chinese species 

 H. rajMX of Grervais. 



Rhysida longipes, (Newport). 



Haase, op. cit., p. 83. 



One specimen sent from Madras by Mr. Thurston. This species 

 is wide- spread, occurring in both the East and West Indies. The 

 British Museum has examples from Burma, Bengal, and Ceylon. 



This species may be recognised from the one following by the 

 strong spine-armature of its anal legs, and by the raised side 

 margins of the tergites in the posterior half of the body. 



Rhysida immarginata, (Porath).
