366 INSECTS. 



to a very large size in Borneo, judging from an enormous 

 skull found whitening on the beach. The owner must 

 at least have been twenty-eight feet long. 



Among the insects, I noticed, as being most common 

 in this province (Unsang) was a species of Monochama, 

 with the elytra elegantly marked with longitudinal, red 

 stripes, alternating with opaque-white stripes marked 

 across with deep black, triangular, spots, and brick-dust- 

 coloured thorax, with three longitudinal black bands. 

 Another truly splendid insect, was a Catacanthus, of the 

 subgenus Chalicoris, with a scarlet body, and head of 

 burnished green ; a thorax of a purple-green with a me- 

 tallic lustre, having a broad, bright scarlet, semi-lunar, 

 transverse band ; the long scutellum, half green and half 

 scarlet, and the elytra white, with green and scarlet marks. 

 Another remarkable form, belonged to Platyrkinidte, a 

 connecting link between the Curcnlionidce and the Longi- 

 corns. It was of a dull, dark, olive-brown, with a bronze- 

 coloured head and antennae, with alternate black and white 

 rings. A species of Mastax, allied to M. vitrea (West. Arc. 

 Ent. t. 22. f. 2.) but differing in the ends of the elytra 

 being incised, was also procured. This species I have 

 named M. Whitei, after that enthusiastic entomologist, 

 Mr. Adam White of the British Museum, to whom I am 

 indebted for the scientific names of many insects previ- 

 ously unknown to ine. It is of a dark brown colour, with 

 two transparent white spots near the ends of the elytra, 

 and wings of a light, semi-pellucid brown. A new species 

 of Scyanm, entirely of a black colour, with light brown, 

 semi-pellucid wings, and several species of Reduvius, a 

 genus which appears in Borneo, and I believe elsewhere,
