A new Walking-Stick (Phasmidae) from British 



Honduras. 



By JAMES A. G. REHN. 



Sermyle phalangiphora * n. sp. 



Type: $ ; Belize, British Honduras. (J. D. Johnson.)

The genus Pseudosermyle has been separated from the older 

 Sermyle chiefly on the character of the male cerci, Scnnyle hav- 

 ing them simple and Pseudosermyle having them with several 

 fingers. Although the cerci are not simple in this new species, 

 the presence of blunt tubercles on the head instead of linear 

 rugosities and the form of the appendage found on the genital 

 opercule induces me to place it in Sermyle, especially in view 

 of the fact that a structure analogous to the one here noticed 

 is found in a less pronounced form in the male of Sermyle 

 physconia, 



The structure of the subgenital opercule and the bifurcate 

 cerci will at once separate this species from any of the forms 

 of Sermyle of which the male is known. 



Size medium ; body bacilliform ; surface smooth. Head slightly 

 longer than the pronotum, subcqual in width ; eyes globose, very 

 prominent; area between the eyes provided with a pair of well spaced 

 low blunt tubercles, a narrow impressed median line extending caudad 

 of a line between the eyes ; antennae about as long as the body, proxi- 

 mal joint nearly half the length of the head, depressed, second joint 

 about half the length of the proximal one. Pronotum distinctly but 

 not greatly longer than broad, a slightly arcuate transverse im- 

 pressed line is present; mesonotum about four nnd a half times the 

 length of the pronotum; metnnotum, including median segment, half 

 again as long as the mesonotum, the median segment subquadrate 

 and about a fourth the length of the remainder of the metanotum. 

 Abdomen slightly shorter than the head and thorax, all the seg- 

 ments to and including the sixth longitudinal, the first to fifth regu- 

 larly increasing in length, the sixth about as long as the second, 

 seventh subquadrate, eighth subquadrate, but slightly shorter and nar- 

 rower than the seventh, ninth slightly longer than the seventh, regularly 

 expanding to about the width of the same segment, the border 

 marginate and with lateral angles rounded and a slight median 



* 4>aAay, a finger joint; <o/oos, that bears.
