Coleoptera. Lycidse. Lycus dentipes, trabeatus, cuspidatus 

 and four other species : Telephoridse, two species. Melyridse. 

 Prionocerus dimidiatus: Phytophaga. Diacantha conifera, 

 Peploptera fidvitarsis ; Cantharidae. Zonitis, one species. Eletica 

 cardinalis. Mylabris palliata : it may be noticed here that 

 the very large and widely-spread distasteful genus Mylabris 

 is in itself an excellent example of Miillerian mimicry : 

 Cerambycidae, Amphidesmus analis, Blepisanis haroldi^ 

 Philayathes l&tus. 



Hymenoptera. Aculeata. Several species of the following 

 genera : Pomjrilus, Cereeris, Rhynchium, JS T otogonia, Salius. 



Hemiptera. Reduvius sertus, and others. 



Lepidoptera. Arctiadse. Dyphlebia eleyans : Zygsenidae. 

 Neurosymploca ochreipennis. 



Diptera. Xiphocerus, sp. 



Nearly all these species occurred within one month in the 

 same locality : since they were sent to England, one or two 

 striking species of Non-Aculeate Hymenoptera, falling into 

 the same series, have been discovered. 



A very large series of insects of all orders have been sent 

 to the Hope Museum, Oxford, by Mr. R. Shelford, Curator of 

 the Sarawak Museum, Borneo, who has recorded several 

 very interesting cases of Miillerian mimicry in a paper 

 communicated by Professor Poulton to the British Association 

 at Bradford, which has before been referred to : while looking 

 over a large mass of the unseparated material the other day, 

 I came across two or three striking species of Blattidae, which 

 in coloration and to a certain extent in form fitted in well with 

 a Miillerian group consisting of Endomychidx and Erotylidse, 

 and a species of Hemiptera, belonging to the Pentatomidee : 

 the general coloration of the group was black and white or 

 yellowish-white, the latter colour being arranged more or less 

 in spots : probably, if the district is further worked, it will 

 be found that many more species occur which will fit into the 

 group — for the coloration is a common one among Carabidse, 

 Curculionidae, Longicornia, etc. : in fact it is the general run 

 of similar coloration that appears to give so much weight to 

 the theory. If we set on one side the sombre-coloured and 

 evidently cryptic groups, we can almost count the schemes
