We are by no means assured that StoU's vitrea and Olivier's venosa 

 do not represent sexes of one and the same species, but we do know 

 that we have two distinct though closely allied species before us, 

 to which we believe have been generally given in the literature 

 the names we are using. So involved is the synonymy at present 

 that we are strongly of the opinion that we here have to deal with 

 an extremely plastic unit, comparable with H. patellifera Serville, 

 and like it, the cause of much confusion in past literature. Conse- 

 quently many features, usually considered of specific diagnostic 

 value, will probably be found worthless for the species under con- 

 sideration. 



For this reason we feel that Giglio-Tos has shown decided temerity 

 in describing Hierodula vitreoides, near vitrea, and Parhierodula 

 simhangaria, near venosa. Were these species adequately described, 

 or figures given, their proper status might be determined. As it is, 

 ■examination of the types and, if valid, redescription with figures 

 -will be necessary. 



In the material here recorded the cephalic coxae have the cephalic 

 margin armed with (eight to nine) moderately well separated spines, 

 which increase moderately in length distad (particularly in the 

 females, length of longest, cf .3, 9 .8 mm.). The costal margin 

 of the tegmina is weakly serrulate, this strongest meso-distad. In 

 the females the pronotum has the margins of the collar moderately 

 denticulate, the denticulations of the cephalic half of the shaft 

 weak, the shaft with medio-longitudinal carina well developed. 

 In this sex the tegmina extend considerably beyond the apex of 

 the abdomen, with marginal field proportionately narrower than 

 in females of venosa and with stigma smaller (length 2.4 and 2.9 

 mm.). 



The adult specimens before us are all dried alcoholic. One only 

 shows the cephalic trochanter with apex slightly darkened, but all 

 show subobsolete traces of darker suffusions on the inner faces of 

 the cephalic femora, as described for venosa. From this feature 

 we believe that H. tenuis Giglio-Tos is a member of the same phy-
