A NEW SPECIES OF THE ORTHOPTEROUS GENUS PSEUDOPHYLLUS 

 FROM SUMATRA. 



BY JAMES A. G. REHN. 



The Academy of Xatural Sciences of Philadelphia has been the 

 recipient of a collection of zoological material from the island of 

 Simiatra, presented by Mr. A. C. Harrison, Jr., and Dr. H. M. 

 Hiller. The collection included an alcoholic specimen of a species 

 of the genus Pseudophyllus, Avhich on examination proves to be 

 new, and which I take pleasure in dedicating to one of the donors. 

 Pseudophyllus harrisoni n. sp. 



Type, female, Coll. Acad. Nat. Sci. Phila. 



Allied to P. neriifolius Serville,^ but differing in the obtuse ante- 

 rior angles of the mesosternum, in the bluntly bituberculate pro- 

 sternum, and the central position of the metasternal foveolse. From 

 P. brullei Pictet and Saussure it is distinguished by the centrally 

 bent transverse veins, and by the anteriorly inserted radial vein. 



Size large. Head with the vertex produced, acuminate, supe- 

 riorly sulcate; eyes subovate, exserted; antennae filiform. Pro- 

 notum with anterior margin subarcuate, posterior broadly rounded ; 

 lateral lobes with the lower margin obtusely trian- 

 gular ; transverse sulci two in number, the posterior 

 very deeply incised. Tegmina elongate, moderately 

 broad; radial vein inserted decidedly before the 

 middle ; transverse vems toward the apex centrally 

 bent, giving them a subarcuate appearance. Wings 

 exceeding the tegmina in length, apex acuminate. 

 Prosternum bluntly bituberculate; mesosternum with the anterior* 

 border sinuate, the anterior angles obtuse and bearing a spine directed 

 downward ; metasternum with the anterior border truncate, as 

 long as the same portion of the mesosternum, foveolaj placed in the 

 central portion, rather close together. Anterior femora with a few 

 very obscure spines on the lower margins ; tibite with the upper

 the synonymy of this species.
