350 MANTIDAE AND PHASMIDAE OF PANAMA 



A paratypic female, Ijeariiig the same data as the type, is also 

 before us. 



Pseudophasma-'' menius (Westwood) 



1859. Phasnia menius Westwood, Cat. Orth. Ins. British Mus., i, Phasmidae, 

 p. 118, pi. XVII, fig. 2. [cf, Colombia.] 



This species has been previously correctly reported from the 

 Rio Cianati, Darien, Panama, l)y Griffini, and from Carrillo, 

 Costa Rica, by Rehn. It is assuredly the insect which Redten- 

 bacher has recorded from Costa Rica and Chiriqui, Colon, 

 Panama, and Darien, Panama, as Phasvia perezii Bolivar.-^ 



Porto Bello, Panama, II, 27 to V, 4, 1911, (Busck; Jennings), 

 4 cf, 3 9. 



Gatun, Canal Zone, Pan., VII, 17 to VIII, 22, 1916, (Harrower), 

 7c^,l 9. 



Culebra, C. Z., Pan., I, 8, 1911, (Dr. Pittier), 1 9 , [U.S.N.M.]. 



This plainly and somberlj'' colored species is apparently the 

 most abundant flying walking-stick in both Costa Rica and 

 Panama. 



Isagoras dentipes Redtenbacher 



1906. Isagoras dentipes Redtcnbacher, Insektenfamilie der Phasmiden, p. 134. 

 [cf; Bugaba and Chiriqui, Panama.] 



Bugaba, Panama, (W. Schaus), 1 cf , 1 9 , [U. S. N. -M.]. 



In these specimens the metasternum is pale, buffycaudad, but 

 not sulphur yellow. 



The undescribed female is decidedly larger than the male 

 with the tuberculation of the body and lamellation of the limbs 

 intensified, while on the latter are developed larger and more 

 numerous lobes (or blunt denticulations). In this specimen the 

 cejohalic femora are much more strongly compressed. The 

 caudal femora have the dorso-external margin supplied with 

 (four or five) small lobes; the dorso-internal margin with six 

 much larger lobes; the ventro-internal margin with a long, low, 

 horizontal l()l)e proximad and a similar, but vertical, lol)e distad, 



^* Tl>c necessity of following Kirby in the use of this name for Phasuia of 

 authors (not of Lichtcnstcin as restricted) has been fully explained by Rehn, 

 Proc. Acad. Nat. Sci. Phila., 1904, p. 95, footnote 43, (1904). 



^^ As Redtcnbacher considered his material from Coca, Ecuador (the type 

 locality of perezii) the same as that from Panama, it would appear very 

 possible that perezii may be a synonym of menius.
