4638 Insects. 



Mount Ophir by a larger species, and the two fine Catascopi of the 

 former place had also their Malacca representatives. I here obtained 

 my first species of Tricondyla, and in the centre of one of the densest 

 and darkest jungles was so fortunate as to fii\p! the strange Mormolyce 

 phyllodes, under a huge boletus, — just where, from its resemblance to 

 the curious Thyreoptera of Singapore, I had expected to discover it. 

 Numerous species of Apoderus were very remarkable among the Cur- 

 culionidae, while most of the curious Anthribidae of Singapore were 

 wanting. Many exquisite species of metallic Cassidas were found for 

 the first time; the Heteromera, too, were very numerous, and the 

 Elaters and Buprestidae furnished me with many new species. Of 

 Lucanidae I obtained eight species, mostly small, though one (the 

 Dorcus Titanus, Boisd.) is quite a giant. 



Amidst this variety of Coleoptera the most remarkable circumstance 

 is the almost entire absence of the great family of the Cetoniadae. 

 Though constantly searching for them I procured but five species, and 

 those all small and single specimens. 



But it was in the other orders that I obtained the greatest amount 

 of novelty and variety. In the little streams about the foot of Mount 

 Ophir were hosts of new and beautiful dragon-flies, and even on the 

 summit, at an elevation of 4000 feet, I obtained one species. Of these 

 interesting but much-neglected insects I nearly doubled my collection, 

 which now amounts to seventy-two species of true dragon -flies. The 

 Hemiptera and Homoptera were perhaps most abundant of all, con- 

 taining many fine species of Paeciloptera and Cercopis, as well as 

 extraordinary Reduviidae and brilliantly coloured Scutellerae. On the 

 muddy pools in the path to Mount Ophir were numbers of a very large 

 and handsome Notonecta, which took the way as we approached, but, 

 settling on the adjacent foliage, were easily captured. Of these inte- 

 resting insects I added a hundred species to my collection, which now 

 amounts to 228 species. The Orthoptera, though much fewer in num 

 bers, were very interesting for the great variety of the Phasmidae 

 and Mantidae. I have species of Mantis coloured like wasps, others 

 like ants, and one brilliantly metallic. The winged Phasmidae ap- 

 peared endless : for a long time every one I captured was a different 

 species, and the greater portion remained to the last unique. The 

 Diptera, too, were very interesting. Among them I obtained the ex- 

 traordinary Celyphus obtectus, or an allied species, which has the 

 head of a fly to the body of a Scutellera among the Hemiptera. I 

 also obtained three species of the curious stalk- eyed flies.
