1920.] NATURAL SCIENCES OF PHILADELPHIA. 67 



We refer to our discussion of the values of the generic characters, 

 used to separate the genera of the Group Hierodulae, under the 

 group heading on page 51. We there explain our reasons for 

 repudiating Giglio-Tos' rearrangement and the new genera and 

 subgenera which he was obliged to erect after he had decided to 

 consider the smoothness or serrulation of the costal margins of 

 the tegmina of primary importance. 



On page 63, under the Tamolana Group of the genus Hierodula, 

 we discuss the majority of the species which Giglio-Tos referred 

 to his subgenus Rhomboderula. 



Rhombodera extensicoUis (Serville). 



1839. Mantis extensicoUis Serville, Hist. Nat. Ins., Orth., p. 189. [c^, 9 ; 

 Java.] 



Samarang, Java, July, 1909, (E. Jacobson), 1 cf, [Academy 

 of Natural Sciences of Philadelphia]. 



This specimen agrees fully with Giglio-Tos' diagnosis of extensi- 

 coUis, which species he placed in his subgenus Rhomboderula of his 

 genus Parkier odula. 



Rehn has recorded the present specimen as Rhombodera flava 

 (Haan),''' which species is closely related and may prove a syn- 

 onym of extensicoUis, as was indicated by Kirby, but resurrected 

 as valid by Giglio-Tos and placed by that author in Rhombodera, 

 which he considered a subgenus of Hierodula. 



Rhombodera stalii Giglio-Tos. 



1877. H[ierodula\ basalts St^l, (not Mantis basalis Haan, 1842), Bih. till 

 K. Svenska Vet. Akad. Handl., IV, No. 10, p. 21. [Java, Borneo.] 



1912. H[ierodula] R[hombodera] stalii Giglio-Tos, Bull. Soc. Ent. Italiana, 

 XLIII, p. 102. [cf, 9 : southern Java; Tengger Mountains, Eastern 

 Java.] 



Nongkodjajar, Java, January, 1911, (E. Jacobson), 1 cf, 1 9, 

 [Academy of Natural Sciences of Philadelphia]. 



These specimens have been recorded by Rehn as R. basalis 

 (Haan).^" Giglio-Tos has proposed the name stalii for a form with 

 narrowed pronotum and apex of cephalic trochanters darkened. 

 The present specimens agree with that author's diagnosis except 

 that they are smaller. 



We hesitate to use the name stalii for we are by no means con- 

 vinced that this type will not prove to be a geographic race or 

 even a mere variant of basalis, unworthy of nominal recognition.
