304 THE ZOOLOGIST. 



had been found on a yellow flower with crimson stamens ; the 

 larva was yellow, with crimson lines on the abdomen and crimson 

 mid- and hind-axse. As far as my observations go, this species 

 cannot change its colour in adaptation to its surroundings with- 

 out moulting. A pink specimen found on a shrub with pink 

 flowers (? Melastoma sp.) was kept under a bell-jar standing on 

 a sheet of white paper. After a few days the larva moulted, and 

 was then pure white. A nymph of Deroplatys desiccata, on the 

 other hand, that was kept for some days in a box lined with 

 white paper, became noticeably paler in colour. 



A full and accurate account of the habits of a pupal 

 Hymenopus bicornis may be found in a paper on the Insects of 

 the Skeat Expedition, by Mr. Nelson Annandale (P. Z. S., pt. iv. 

 1900, pp. 839-848). The same paper contains notes on other 

 Malayan Mantidce. 



Description of a New Species of Mantidce referred to in the above 

 paper by W. F. Kirby, F.L.S., dec. 



Deroplatys shelfordi, sp. n. 



Long. corp. 60 millim. ; long. pron. 30 millim. ; lat. 26 millim. 



Female. — Dead-leaf brown ; pronotum of a long bell-shape, regu- 

 larly curved and expanded backwards to its greatest breadth, the hind 

 border curving backwards and inwards to the extremity; lateral 

 borders denticulated on the basal half. Tegmina with no distinct 

 markings except a narrow yellowish discal stripe ; wings banded with 

 blackish, and produced into long processes at the extremity, as in D. 

 truncata, Gu6r. Spines of the front femora and tibiae more or less 

 tipped with black ; front femora with a black band towards the 

 extremity on the inner side, intersected by two or three short yellowish 

 stripes ; front coxae with six or eight short straight spines. 



Hab. Borneo ; Sarawak (Shelford). 



Apparently intermediate between D. truncata, Gu6r., and D. 

 horrifica, Westw., resembling the former in shape, and the latter 

 in markings.
