into two alternating series, discoidal spines four in number; cephalic 

 tibiae slightly more than half the length of the femora, external margins 

 armed with eight to ten spines which leave un- 

 armed a considerable proximal area, internal mar- 

 gins with a regularly enlarging series of eleven 

 to twelve spines; cephalic tarsi somewhat longer 

 than the tibiae without apical claw, the metatarsi 

 alone but little shorter than the tibise. Median 

 and caudal limbs very slender, the caudal femora 

 about five-sixths the length of the pronotum. 

 General color ochraceous, the head inclined 



J- iQ Staqmo- toward ochraceous-rufous, the ventral surface of 



mantis gracilipes the thorax and abdomen chrome j'ellow, the median 



liinb' of ^^t\i)e^ ^^'^ caudal femora deepening to blackish brown 



(X 2.) proximad. Tegmina brownish hyaline, the costal 



field opac^ue, probably green in life, the costal 



and discoidal fields separated by a wash of russet which fades rapidly 



on the discoidal side. Wings with the costal margin marked with 



russet, the remainder wdth subquadrate patches of seal brown such as 



are frequently found in the genus.

The type is the only specimen of this interesting species which has 

 come to the author's attention. 



Vates paraensis Saussure. 



Babociuivari IMountains, 1 9 . 



This specimen has been compared with an undoubted Guadalajara 

 female of this species and is inseparable from it. In size it is slightly 

 larger, but well within the measurements given by Saussure and Zehnt- 

 ner. The species described by the author as V. townsendi can readily 

 be separated from paraensis by the more compressed pronotal shaft, 



'^ The distal section of the abdomen is missing.
