General color (undoubtedly discolored in drying untl probably 

 green in life) ochraceous-tawny. Head chestnut-brown (^doubtless 

 discolored). Tegmina yellowish-glaucous, mytho-green distad, the 

 latter probably the natural color of the whole tegmen. Wings hy- 

 aline, faintly yellowish. CephaUc femoral and tibial spines weakly 

 tipped with black or pitch black. 



Length of body, 28.8 mm.;'-'- length of pronotuin, 11.2; greatest 

 width of supra-coxal expansion of pronotum, 3.4; length of tegmen, 

 20.5; greatest width of tegmen, 8.5; greatest width of marginal field 

 of tegmen, 2.6; length of cephahc coxa, 8.8; length of cephalic femur, 

 10.5; length of caudal femur, 10.5; length of caudal tibia, 10. 



The type is unique.

Rio de Janeiro. One female. [M. C. Z.] 



This specimen is perfectly typical of the species, but shows some 

 difference from the descriptions in having a second pair of tubercles 

 on the mesonotum cephalad of the usual pair, the extra ones being 

 developed as a strong spine (right side) or as a short conical tubercle 

 (left). 



The species has been previously recorded from this localit}'.

-- Approximate, as the apex of the abdomen is twisted out of its normal plane. 

 23 \\^p have examined the unique tvpe of Phasma rndiatum Scudder (Proc;. 

 Bost. Soc. Nat. Hist., XXVII, p. 279," (1875)), and find that Kedtenbacher (In- 

 scktf. Phasm., p. 105, (1906)), has properly phiced this species in the genus »S7/-o/o- 

 cles, and has correcth^ interpreted the features of the species. Although the 

 material examined by Redtenbacher was of the female sex and the type is a 

 male, the characters assigned by him are all those of the type, except for rela- 

 tively minor ones of the abdominal and limb coloration, and these may be sexual 

 features. In the type the apex of the abdomen is solidly blackish, without any 

 indication of the lateral ferruginous and the marginal greenish mentioned by 

 Redtenbacher. The caudal tibiae in the type have the dorsal surface lined with 

 ferruginous except proximad and distad, where the general blackish-color is 

 found. Redtenbacher says the tibiae are uniformly fuscous-black, along with 

 the tarsi. The caudal tarsi are pale ferruginous in the type, while those of the 

 other limbs are as described by him.
