W. D. Fuxkhouseu. 



(Contribution from the Entomological Laboratory of 

 Cornell University. ) 



Through the courtesy of Professor C. F. Baker, Dean of the 

 College of Agriculture at Los Banos, Philippine Islands, I have 

 beeu permitted to study a very interesting series of insects of the 

 family Membracidae collected during the Summer of 1917 at Singa- 

 pore and the Island of Penang. 



The collection contains twelve new species and records of a 

 number of species of AValker. Distant. Melichar and Bierman which 

 form a valuable addition to our knowledge of the distribution of 

 the Indian homopterous fauna. 



All of the species listed were collected by Professor Baker. 



1. Xiphistes orientalis, sp. nov. 



Uniform reddish-brown: thick bodied; horns heavy and blunt; 

 tegmina opaque; scutellum largely exposed. 



Head dark brown with faint median ferruginous line, rugous, 

 closely and finely punctate, sparingly pubescent with brownish hairs ; 

 eyes large, prominent, grayish-white; ocelli prominent, pearly, 

 about equidistant from each other and from the eyes and situated 

 on a line drawn through centers of eyes : clypeus much longer than 

 wide, extending for more than half its length below inferior margin 

 of face, pubescent, tip rounded. 



Prothorax black-brown, rough, very pubescent with short, red- 

 dish-brown hairs which almost entirely conceal the weak punctua- 

 tion ; humeral angles very large, heavy, triangular and blunt, pro- 

 jecting directly laterad; suprahumeral horns short, very stout, 

 about as long as their width at base and about as far apart at their 

 bases as the basal width of one horn, projecting upward, outward 

 and slightly forward, upper surfaces very rough and nodulose with 

 irregular carinae. tips blunt, rounded and somewhat deflexed ; 

 median carina strongly percurrent : posterior process long, almost 

 straight, slightly deflexed at tip. strongly centrally carinate, base 

 laterally carinate on each side, tip gradually acute and extending 

 about half way between internal angles and tips of tegmina. base 

 only lightly touching scutellum; scutellum plainly visible on each 

 side.
