6 Indian Museum Notes.- [Vol. VL 



Owing to the position of the egg when laid, it will be seen that an 



ovipositor of this or similar form is necessary Nine or ten eggs 



are generally found in the body of a mature female, as, owing to 

 their large size in comparison to the insect itself, there would 

 scarcely be room for more. It is possible that more eggs are formed 

 as they are laid." 



11 It will be seen by referring to Mr. Waterhouse's description of 

 the insect that no mention is made of the colour or markings of the 

 abdomen ...,., The abdomen in fresh specimens of both sexes is- 

 invariably bright emerald green by transparency, marked dorsally on 

 the third to the ninth segments with shiny dark brown. The extent 

 of brown on the third segment is limited to a small dorsal patch or is 

 altogether absent ; on the fourth it extends over the whole dorsal 

 region : on the fifth partially lateral and wholly dorsal: the remaining 

 segments are all dark brown : the segmental divisions are greenish* 

 The male differs from the female in having the pronotum very slightly 

 tinged with yellow: the abdomen more slender and the absence of 

 the ovipositor. The larvae are greenish with deep ochreous or orange 

 legs and antennae : in some the abdomen is distinctly yellowish^ 

 although the same becomes green after having fed.''' 



With the exception of the last sentence this description agrees in 

 every particular with the insect as found in the districts above named- 

 I have, however, never been able to detect any change in colour of 

 the larvae. From their earliest development to their last moult the 

 colour of the larvae varies from an orange brown to a bright emerald 

 green, a difference for which one cannot at present account. 



To this description one can, however, add further details as to the 

 form and venaiion of the wings, as to the form of the tarsus and leg 

 as to the structure of the scutellar horn, as to the formation of the 

 rostrum and as to the form of the ovipositor and the anus of the 

 female. All of these are illustrated in Plates I and II, the figures 

 being directly drawn from preparations made from Cachar insects 

 hardened in alcohol. 



Wings.— The hemelytron is long and rather drumstick-like in 

 shape averaging in length 6*4 mm. The clavus is well developed but 

 triangular in shape being widest at the root of the wing. The corium 

 is not hard, being little thicker than the remaining part of the wing- 

 It passes into the cuneus without any division. The membrane 

 has only one vein irregularly shaped as shown in the figure. The 

 wing membrane {see fig. 3, Plate I) is covered with very microscopic 

 hairs, and the edge is, as shown, very distinctly hairy. The hind
