Proterrliinus was not very well represented with about half a 

 dozen species of no particular interest, two of the nicest species being 

 apparently out of season. Several species of Gis, one probably pe- 

 culiar to this mountain and the finest in the Islands, and one of 

 Xylehorus, burrowing as usual in the dead and decaying Olapa trees, 

 were more or less common. 



Brachypeplus was represented by four or five species, one of 

 which, living beneath the bark of the Koa, was a peculiar form, ex- 

 cessively flattened and not known to me from elsewhere. A single 

 large specimen beaten from flowers of Smilax is probably referable to 

 the allied genus Gonioryctus. 



Anobiids were numerously represented by species of the two 

 endemic genera, Xyletohius and Ifirosternus, and for the first time I 

 managed to get a fair number of Holcohius iu two or three species. 

 These latter far exceed the species of the two first-named genera in 

 size, and for the Islands are quite fine insects. Their habits are alto- 

 gether nocturnal, those of the other two genera diurnal. 



Singly and rarely as usual were found specimens of Brontolcemus 

 and LoBmopliJcBus ceneus, but the former did not seem to me identical 

 with those on the other Islands, trusting to memory. 



Elateridcs were evidently not fully in season, as I saw more of the 

 larvse than the beetles. About half a dozen of a probably new species 

 of Eopenthes were only taken. Under bark and in wet logs were two 

 or three species of Fornax, one of which I bred from long wireworm- 

 like larvEB. A larger black species, previously found on Hawaii, was 

 also here but not in season, as I saw only fragments of the beetle but 

 got the pupa and larva, the latter very different to those of the smaller 

 species and burrowing in the hardest wood. 



The endemic Longicora genus Glytarlus was represented by five 

 species, three attached to Acacia koa and two (both new species) to 

 Sophora chrysophylla, another Acacia. These beetles are generally 

 found running swiftly over the trunks and limbs of trees in the hot 

 sunshine. While the female is ovipositing in the chinks of the bark 

 the male walks with her, his front legs clasping the shoulders, the 

 others on the surface of the tree. Pairing takes place afresh 

 before the laying of nearly every egg, but is of very short duration 

 after the initial act. The males often disi)osses8 one another of their 

 partners, and both sexes frequently get mutilated in their struggles. 

 A laying female, if unattended, is sure to be seized on by the first male 

 that passes near. On capture they stridulnte very audibly, and ob-
