Earn. ANOBIIDAE'. 



The Anobiidae are represented by three genera containing endemic species, and 

 by three genera containing species which are certainly introduced. Of the former, one 

 genus also inhabits the warm parts of America, the other two are endemic. These 

 genera contain, as here described, or listed, 1 34 species divided as follows : Holcobuts 

 12, Xyletobms 52, JMirosternus (the non-endemic genus) 70. The three other genera 

 contain in all but five species. In addition to these there are, I believe, one or two 

 species representing other genera, which have been quite recently imported into 

 Honolulu. Material is not at hand for the determination of these. So far as my own 

 experience in working out Hawaiian insects is concerned, I have found the large genera 

 Xyletobius and JMirosternus by far the most difficult of any group that I have under- 

 taken, and I need hardly say that I am far from satisfied with the result, in spite of the 

 great length of time that I have spent on this work. I think that years of careful 

 observations in the field as well as in the study would be necessary for acquiring 

 a thorouoh knowledge of these difficult insects.

The species of Holcobius are much less numerous, and the individuals much less 

 easily procured, than many of those belonging to Xyletobius and Mirosternus. I have 

 seen one or two of the species flying in some numbers at dark and all are nocturnal. 

 Three of the species have not the form of palpi characteristic of Holcobius and will, 

 doubtless, be removed from the genus. The following groups are easily recognized.
