About a score of species of Carabidae are found in the immediate 

 neighborhood of the volcano, many of the species are rare and 

 require special search. The fern forest near the hotel vegetable 

 garden is about the best locality. The large Barypristus r^upicola 

 is, however, confined to the neighborhood of Koa trees. The 

 following list includes such species only as are found near the 

 volcano, others no doubt frequenting Olaa and Hilo and lower 

 elevations on the Kau side. Barypristus rupicola, Colpodiscus 

 lucipetens, Colpocacctis hawaiiensis, C. apicalis, Atelothrus hawaii- 

 ensis, Mesothriscus hawaiiensis, ]\ietromenus lentus, Mecy do- 

 thorax konanus, vulcanus, pele, hemhidicus, Thriscothorax bembi- 

 diodes, paradoxus, discedens, variipes, Metrothorax deverilli, 

 laticollis and Bembidium ignicola. 



The Staphylinidae are represented by a number of excessively 

 minute, but remarkable, native species. They require very 

 special search, if they are to be obtained in numbers, and the 

 most careful mounting, when secured. Few of the species are 

 much more than a millimetre in length and they are of very 

 delicate build, and easily spoiled by rough handling. Probably 

 the species are still more numerous in Olaa. 



Histeridae are represented by only one or two minute species, 

 but the Nitidulidae are well represented, one or two of the species 

 being of remarkable structure and not surpassed in interest by 

 any other island species. Probably there are eight or twelve 

 to be found at Kilauea and others in Olaa. 



Cucujids are as usual represented by a Brontolaemus and a 

 Laemophloeus, the latter being rare. 



Cioidae yield at least thirteen species of Cis and two of Apter- 

 ocis. On my recent visit I took a single specimen of Cis haleak- 

 alae, described on a unique from Maui, a most interesting and 

 unexpected capture. 



Anobiidae are very numerous in individuals and the species 

 are also numerous; in fact their extreme abundance is, as I have 

 noted, a feature of the forest on the Kau side. Hundreds of 

 specimens can be taken in an hour or two. The three genera, 

 Holcobius, Xyletobius and Mirosternus are all represented, the 

 two latter most numerously. 



Elateridae are numerous in individuals and both Jtodacnus 

 and Eopenthes are found. The species are not yet described.
