Tenodera super stitiosa (Fabricius). 



1781. [Mantis] superstitiosa Fabricius, Species Insect., I, p. 348. [.Equinoc- 

 tial Africa.] 



One female; Trong, Lower Siam. (Dr. W. L. Abbott.) [U. S. 



N. M.] 



Genus PARATENODERA n. gen. 



Typo. — Tenodera sinensis (Saussure). 



This genus can readily be separated from Tenodera s. s. by the stouter 

 and heavier form, much less elongate pronotum, the broader head, 

 the higher facial shield and the heavier anterior limbs. The principal 

 differential characters would be as follows : 



A. — Head with the facial shield about three times as broad as high; 

 pronotum with the collar about one-fifth of the total length of 

 the pronotum; anterior coxse with the lower margin with very 

 obsolete denticles, Tenodera Burm. 



yL4.— Head with the facial shield about twice as broad as high; pro- 

 notum with the collar not less than one-fourth of the total length 

 of the pronotum; anterior coxse with the lower margin strongly 

 denticulate, Paratenodera Rehn. 



Paratenodera aridifolia (Stoll). 



1787. [Mantis] Aridifolia Stoll, Natuurlij Ice Afbeeldinsjen en Beschrijvingen, 

 Spooken, pp. 65, 78, Pi. XXII, fig. 82. [East Indies.] 



Ten specimens; one male, nine females: 



Trong, Lower Siam. (Dr. W. L. Abbott.) [U. S. N. M.] 



Goenong Soegi, Lampong, Sumatra. October-November, 1901. 

 (A. C. Harrison, Jr., and Dr. H. M. Hiller.) [A. N. S. Phila.] 



These specimens are quite constant in size, and in the series exam- 

 ined both the brown and green phase of coloration are present, and in 

 about equal proportion. 



Paratenodera sinensis (Saussure). 



1871. T[enodera] aridifolia var. sinensis Saussure, Melanges Orthopterolo- 

 giques, III, Suppl., p. 419. [Ningpo, China.] 



Thirty-two specimens; twelve males, twenty females;: 



Kioto, Japan. (Y. Hirase, Nos. 32 and 33.) [A. N. S. Phila.] 



Yokohama, Japan. (Loomis.) [A. N. Caudell.] 



The above excellent series shows that the full brown phase of color- 

 ation is apparently rather scarce in sinensis, as it is present in but two 

 out of thirty-two specimens. In a series of eighteen specimens of this 

 species, taken from the introduced colony at Mt, Airy, Philadelphia, 

 the proportion is two in eighteen. The variation in size is rather great,
