INTRODUCTION cxxxiii 



Mycetophagidae. — Of the two species of Lihirgus, L. balteatus is American, and 

 L. vestitiis, though described from the islands, will doubtless prove to be foreign, as it 

 has been found out of the range of endemic beetles on foreign trees. I think that 

 both species occur in the town of Honolulu at times, and one or other species of the 

 genus sometimes abounds in decayed stems of sugar-cane. Propalticus oculahis is 

 also certain to prove an introduction, for though it occurs in the forests, we find it in the 

 town of Honolulu,, sometimes in dead stems of introduced Hibiscus. TypJiaea ftimata 

 is of course an importation. 



Mycetaeidae. — Represented only by the introduced Mycetaea hiria, and it is 

 uncertain whether this has become established. 



Lathridiidae. — Only represented by the foreign Lathridius nodifer and Colovocera 

 maderae, the latter first observed in 1900 in foreign ants' nests, in and close to Honolulu. 

 L. nodifer, though widely distributed, only occurs in very small numbers, usually 

 amonofst fallen leaves in the forest.

Cryptophagidae. — Cryptophilus integer an introduced species, found in Honolulu, 

 and the European Henoticus serraius, also, no doubt, imported, are the only repre- 

 sentatives of this family. 



Cucujidae. — This family is of more importance than the several preceding, though 

 six of the eight genera represented are represented probably by only foreign species, 

 importations by man. Bronto/aetnics is an endemic genus with four closely allied 

 species, showing considerable variation, and they are mostly difficult to distinguish. 

 They are nearly always found on trees affected by the longicorn beetles, especially 

 Clytarhis and Plagithmysus, occasionally on the Kukui tree [Aieurites) when the foreign 

 longicorn Oopsis nutator is breeding therein. The six described species of Parandrita 

 are still more difficult to separate and are imperfectly known owing to the rarity of most 

 of the species. They apparently have the same habits as Brontolaetmis, but usually 

 occur singly or only one or two examples together, whereas e.xamples of the latter are 

 frequently found in some numbers together. 



Laeinophlaeiis minuius is an imported species and may be found in Honolulu 

 beneath the rind of Hibiscus and other trees attacked by other beetles. It is often 

 very common in stores in Honolulu, being numerous in rice and other produce, in 

 company with the usual insects affecting such produce. 



Psammoechus insularis and other species of the genus as well as Monanus have 

 been found in plants imported from other countries and, doubtless, are all introductions 

 by man, while Cryptotnorpha desjardinsii comes under the same category. It is an
