elytra much broader and their colour diversified by black nervations in the 

 new species. . . 



3. The mesosternal lobes are nearly straight along the inner edge in 

 H. banian and leave a larger space between them than in H. nigro-repletus ; 

 in the latter species this space takes the form of an ''X " widened at the 

 anterior and posterior ends. 



4. The metasternal lobes are approximated over a greater length in 

 H. banian than in R. nigro-repletus, almost joining in the form of a suture. 



5. The anal organs differ much in the two species. The two oblique 

 wing-like lobes which are at the base of the .supra anal plate in H. nigro- 

 repletus are lacking in H. banian ; the cerci in H. banian S are bifid in 

 H. nigro-repletus J are simple ; the subgenitai plate in if. banian S is very 

 long and conical in shape, in R. nigro-repletus it is short ; the valves of the 

 ovipositor, in K. banian $ are long and narrow, the inferior ones having at 

 the base two teeth of which one is very small ; in the 5 of the new 

 species, the valves are short and the teeth at the base of the inferior ones 

 are very strong and stout. 



The accompanying figures 1 and 2 show a normal female and a microp- 

 terous male respectively of the new species H. nigro-repletus. A comparison 

 of these figures with corresponding figures or specimens of H. banian will at 

 once reveal the marked difterences existing between the two species. 



Along with the specimens of this new species of Hieroglyphus, further 

 specimens of another micropterous form, which was found in small num- 

 bers associated with ILieroglyplms banian in the paddy fields at Anavatti, 

 were sent to Prof. Bolivar. He has erected a new genus Rieroceryx 

 to include this form and another Indian species to which Saussure had 

 given the manuscript name of Rieroglyplius bilineatus ; this latter species I 

 have not seen. As Bolivar's descriptions are inaccessible to most Indian 

 workers, I give them herein full, together with a synopsis of his comments. 



Gen. Rieroceryx nov.

This genus is close to Rieroglyphus Krauss. The following features how- 

 ever distinguish it from the latter. 



1. The general appearance is different, resembling more the genus
