AN EXPEDITION TO MOUNT KINA BALU. 77 



amongst the Orthoptera, quite a number of species which, accord- 

 ing- to Dr. Sharp, are probably new, and their identification is 

 unavoidably left for some future occasion. 



Some of the most remarkable Insects on Kina Balu, 4200', 

 were certain forms which Dr. Sharp considers to be coleopter- 

 ous larva?, probably of Lycides. They were constantly brought 

 in by my men in handsful, and I collected them myself on the 

 ground, on rotten pieces of wood, and on low shrubs. These 

 larvae resemble in many points certain larvae which I collected 

 on Bukit Timah, Singapore, and on Maxwell's Hill, Perak, and 

 which, according to Dr. Sharp, belong to another species of 

 Lycides. It is apparently this form from the Malay Peninsula 

 which is figured by C. J. Gahan, XATUEAL SCIENCE, Vol. VII 

 (1898), p. 43, in an article on the carboniferous Dipeltis. Since, 

 however, Gahan's figure is not accompanied by a description and 

 since, as far as I know, the larva from the Malay Peninsula has 

 never been described, I have thought it advisable to give the 

 following description of it. 



The animal is remarkably flat and leaf-like, only a few parts 

 of its body exceeding 1 mm. in thickness, the greatly expanded 

 lateral portions of the thorax being even thinner. The head is 

 very small, 1-5 mm. across, and can be retracted within the cavity 

 of the prothorax, and is always so in dead specimens. Eyes very 

 small, black. Both maxillary and labial palps are cone-like struc- 

 tures, with four and three joints respectively, the basal joint in 

 each being very much broader than the distal joint. Mandibles 

 small. The antennae are very short club-shaped bodies, about 

 0*08 mm. in length and 0*5 mm. in greatest thickness. There is 

 a chitinous ring round the narrow base, distally followed by a 

 crown-like chitinous structure, consisting of a broad ring from 

 which four lobes arise lying close round the ' club.' In the living 

 specimen, the antenna? often appear as if they themselves were 

 retractile, but as at the slightest disturbance the entire head is 

 withdrawn inside the tubular cavity of the prothorax, and the an- 

 tennae are so very minute, nothing definite could be ascertained. 

 The prothorax is somewhat triangular, about twice as broad as 

 long ; both mesothorax and metathorax are nearly three times 

 as broad as long, and the posterior border of the metathorax is 

 deeply concave. Of the abdomen, nine segments are visible ex-
