THE FAUNA OF A DESERT TRACT IN SOUTHERN INDIA. 207 



III. Stylopyga rhombifolia, Stall. 



S. decorata, Brunner in Ann. Mus. Genova, (2) XIII., 1893, p. 35. 



Dorylaea rhombifolia, Kirby, Cat. OrthopL, I., 1904, p. 135. 



Solitary females of this Cochroach are not uncommon in August under stones on the 

 stretches of almost bare sand on the Indian shore of Pamben Passage. 



The species is widely distributed in the Tropics of both Hemispheres. We have a 

 specimen from Zanzibar, and others from Java, Upper Burma, Chota Nagpur, and Cal- 

 cutta, in the gardens of which the species is common under flower-pots. Brunner records 

 5. decorata from Mandalay. There are specimens in the collection of the Entomologist 

 of the Government of India from Bombay and Bihar. 



IV. PSEUDOGLOMERIS FLAVICORNIS. (Burm. 



P. flavicornis, Bolivar in Ann. Soc. Ent. France, LXVI., 1897, p. 300 ; Kirby, Cat. 

 OrthopL, L, 1904, p. 190. 



Several males and females from the town of Ramanad. The latter agree very 

 closely, except that their feet are rusty instead of white, with Bolivar's description of an 

 Indian specimen which he identified a little doubtfully with Burmeister's Derocalymna 

 flavicornis. 



In the male the head, pronotum, lower surface of the body and base of the 

 tegmina are pitchy black, which fades to very dark brown towards the margin of the 

 tegmina ; the anterior part of the wings is tinged with the latter shade, the posterior clear 

 and almost colourless ; the antennae, tibiae and femora are rusty, the palpi bright 

 yellow, the tarsi and cerci fulvous, the dorsal surface of the abdomen rich golden brown, 

 becoming darker in front. The pronotum entirely covers the head ; it is large, depressed, 

 subtriangular, densely punctured, slightly raised in the centre; the tegmina are long and 

 narrow, rounded at the extremity ; the wings large. The abdomen is flat above and 

 below, having extremely little depth ; the wings and tegmina fit very close to it when 

 folded. The cerci are very 7 short, as also are the legs. 



In life the body of the female is even less compressed than would appear from dried 

 specimens. 



Both sexes are admirably fitted for living under the bark of trees, in which position 

 I found them abundant on Tamarinds at Ramanad. They insinuated themselves with 

 such agility into the lowest cracks that it was very difficult to dislodge them. The 

 slightly-arched dorsal surface of the females doubtless protects them from being crushed 

 under such conditions, while the flatter males are shielded by their tegmina. 



D. flavicornis was originally described from Java ; Kirby records the species from 

 Tenasserim and Cambodia; Bolivar's specimen apparently came from Southern India. 

 The following are the dimensions of specimens from Ramanad : —
