cxxxii FAUNA HAWAIIENSIS 



connection between the two, though their habits are not known. Like the Anobiidae 

 they sometimes frequent the foliage of plants, and some of them have a striking super- 

 ficial resemblance to certain species of the former. These superficially similar species 

 in the two groups are sometimes actually found in company. On^one occasion an 

 Anobiid was found far below the usual range of these insects, near the coast, and even 

 in this case a Labroceriis i^L. airtico'nis) was found on the same tree. It seems possible 

 that the larvae of these Dermestidae prey on the Anobiidae. Larvae of Dermestids 

 beaten from dead branches of trees in the forests, no doubt belong to Labrocerus, 



Attagenus plebeius is often found in houses, and is certainly introduced, as also are 

 the two species of Crypiorhopalwn, both of which are found in Honolulu and probably 

 all over the islands, on the lowlands. The larva of one species is often noticed on 

 the sheath of dead palm leaves, when these fall from the trees. The two species of 

 Dermestes, common introduced species, are abundant in carcases of dead animals, and 

 range to high elevations in the mountains. 



CocciNELLiDAE. — Only four species of this family occurred in the islands twenty 

 years ago, but since that time numerous genera and species have been imported for 

 economic reasons. These have now, many of them at least, become the commonest 

 and most ubiquitous of insects. The four species found by Mr Blackburn, all still 

 occurring, are, doubtless, importations by accident, excepting perhaps Scyninus ocellatus, 

 which might be an immigrant. I have been told that this species is identical with a 

 species in the Galapagos Islands. S. discedens Sh. appears to be the »S. debilis of 

 Leconte and S. vividus Sh. is said to be S. loewii of Mulsant. Cycloneda abdominalis 

 is certainly much less numerous than was the case twenty years ago, but now it has to 

 compete with a number of other introduced species, which have the same food and are 

 far more successful. 



Erotylidae. — Represented only by Euxestus minor not known from elsewhere, 

 but probably an importation, as it has only been found on Oahu, and by Eidoreus 

 minutus, which has been found actually in Honolulu, and is very unlikely to be 

 endemic. 



CoRYLOPHiDAE. — The five genera of this family contain, so far, only six species, 

 which are all known only from the islands at present, and four of these have only been 

 found on Oahu, mostly near Honolulu. Sericoderus piibipennis and Orthoperiis 

 aequalis are of wide distribution throughout the group, in the mountains, and are found 

 in fungi on Koa and Kukui trees, but it is probable that these, as well as all the others, 

 will be found elsewhere. These others belong to the genera Sacium, Anisomeristes and 

 Corylophodes, the latter with two species.
