266 Mr. R. Shelford’s Studies of the Blattide. 
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, un. sp. (Plate XVI, fig. 10.) 
¢. Head castaneous, antennz rufo-fuscous. Pronotum trapezoidal, 
castaneous, sides deflexed. 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-castaneous, 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 tegrmina 14 mm. 
Mr. Marana, 3000 feet. One example [No. 21]. 
The secondary sexual characters of the Oriental species 
of Zschnoptera 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 Blattide. 
Genus PSEUDOPHYLLODROMIA, Br. 
Pseudophyllodromia pulcherrima, n.sp. (Plate XIV, fig. 3.) 
d.and 9. Piceous. Head large and broad projecting beyond 
the pronotum, with a narrow golden line between the eyes; antennze 
fine, setaceous, longer than the body. Pronotum trapezoidal, sides
