COLEOPTERA 6ii 



there is a more or less distinct fuscous band or marking, caused by a change of colour 

 in the tomentum. A specimen with rufescent elytra taken with the others is also clearly 

 the same species. 



Hab. Molokai, Hawaii. — Hawaii, Kilauea; Molokai, 3000 ft., the variety. 



(48) Xvlctobiiis liiicatus Sharp. 



Xylctohiiis liiicahts Sharp, Tr. Dublin Soc. 1S85, p. 159. 



This species, if I am correct in my identification, is one of the most abundant of all 

 Xyletobiiis and very variable in colour. It is particularly abundant on the uplands of 

 Hawaii, but occurs on all the islands. On Maui only a few examples were collected 

 and hardly any I think on Lanai or Molokai, but the specimens from these three islands 

 were so roughly handled in mounting by not very skilled workers, as to be spoiled for 

 practical purposes. F"rom Oahu and Kauai good specimens were available. 



Specimens from the West side of Hawaii at elevations of 3000 — 5000 ft. or more 

 are generally darker than those from 4000 ft. on the other side. Four individuals in 

 I 20 examined from the former locality are entirely black, while from the other side only 

 one in over 1500 is of this variety. It is convenient to name this melanochroic form: 



X. liiicatjis van holoinclas nov. 



Niger, antennis pedibuscjue nigris. 



Another very distinct form has the elytra black and is broadly red on the apical 

 portion and may be called var. apicalis. 



X. /hicafus var. apicalis nov. 



Elytris nigris aut nigricantibus, apicibus late longeque rufis, ibique pallide 

 tomentosis. 



This variety was rarer on the West side, only two examples in 120 examined were 

 discovered. From the other side 1 100 were counted, one in twenty being var. apicalis. 



On Oahu most of the examples were very small and narrow, but some occurred 

 with these that were inseparable from some individuals taken on Hawaii and others on 

 Kauai. No var. apicalis was found. 



Some of the Kauai specimens were large and with a tendency to greater elongation 

 ot the antennae, some identical with those from Maui and Oahu. 



The species as a whole is excessively close to X. lasiodcs and the latter may be 

 only a race or variety, yet the different character of the pubescence or tomentum on the 

 elytra readily separates the two, unless it be in very exceptional cases. The variation of 

 the two forms is very different.
