266 Mr. R. Shelford's Studies of the Blattidm. 



the opening of the so-called " repugnatorial " glands in 

 many species leads to modifications of the penultimate or 

 antepenultimate terga, but not to that of the supra-anal 

 lamina. 



Ischnoptera montis, n. sp. (Plate XVI, fig. 10.) 



^ . Head castaneous, antennse rufo-fuscous. Pronotum trapezoidal, 

 castaneous, sides defiexed. Tegmina testaceous-hyaline, thirteen to 

 fourteen costal veins, anterior ulnar vein quadri-ramose, posterior 

 ulnar tri-ramose. Wings hyaline, mediastinal vein long with two 

 branches, radial vein unbranched, eight costal veins, the four 

 proximal ones incrassated, median vein simple, ulnar vein giving off 

 five veins to apex and three to the dividing vein. Abdomen cas- 

 taneous, the first few segments paler ; the first segment above with 

 a median deep depression, the anterior wall of which is fimbriated 

 with rufous hairs that appear to conceal a minute orifice, from the 

 posterior wall projects a blunt tooth ^covered with a rufous pube- 

 scence. The middle of the seventh segment is depressed and the 

 middle of the posterior margin of the sixth segment is slightly 

 elevated, forming a wide- mouthed tube in which can be seen 

 numerous hairs. Supra-anal lamina trapezoidal ; subgenital lamina 

 asymmetrical with two acuminate styles asymmetrically placed, 

 the right being almost median, the left lateral. Cerci castaneous, 

 mutilated. Legs rufo-caslaneous, front femora with several spines 

 along the anterior margin beneath, the distal members of the series 

 shorter than the proximal. 



Length of body 13 mm. ; length of tegmina 14 mm. 



Mt. Matang, 3000 feet. One example [No. 21]. 



The secondary sexual characters of the Oriental species 

 of Ischnoptera appear to be most diverse in character, and 

 a careful anatomical study of the structures whose pre- 

 sence is revealed by openings to the exterior and modifi- 

 cations of the overlying terga is much to be desired. 

 The modification of the first abdominal tergum described 

 above appears to be unusual amongst the Blattidse. 



Genus Pseudophyllodromia, Br. 



Pseudophyllodromia'pulcherrima, n.sp, (Plate XIV, fig. 3.) 



(J . and $ . Piceous. Head large and broad projecting beyond 

 the pronotum, with a narrow golden line between the eyes ; antennae 

 fine, setaceous, longer than the body. Pronotum trapezoidal, sides
