2 34 FAUNA HAWAIIENSIS 



narrowed behind but scarcely at all sinuate, the lateral and basal margins are quite fine, 

 the latter very broadly interrupted in the middle, the hind angles are moderately definite 

 and slightly obtuse. The fourth joint of the hind tarsus is quite as large as it is in 

 M. caliginosus, but the fifth joint is not inserted so near the base of the fourth, hence 

 the tarsi are a little less lobed. 



Hab. Oahu. Halemano, 2000 ft., December 1892. 



A variety occurs in which the colour is entirely yellow, with a slight infuscation of 

 the head ; this superficially resembles 1\I. nnitabilis, but that species has the tarsus much 

 more bilobate. This variety was found in the Waianae mountains, 2000 ft., February 

 and April 1896. Six specimens.

(5) Mciromcinis angustifroits, sp. nov. 



Piceus, sat nitidus, elytris nigris, margine externo suturaque rufis, antennis pedi- 

 busque testaceis ; capite angusto ; prothorace leviter transverso, basin versus sat 

 angustato, angulis posterioribus obtusis, haud rotundatis ; elytris profunde striatis. 

 Long. 6 mm. 



This may be compared with M. caliginosus, but it cannot be confounded therewith 

 on account of the narrower and longer form of the head and the fact that the eyes are 

 not prominent and exhibit only a very slight convexity. The hind angles of the thorax 

 are less rounded than they are in M. caliginosus, and the striation of the elytra is 

 deeper : the yellow margin along the external groove of the elytra is very conspicuous. 

 It is equally near to M. protei"inis, and in some respects is intermediate between it and 

 M. caliginosus, but it has less convex eyes, a smaller thorax, and less elongate, less 

 deeply striated elytra. Only one specimen has been found.

(6) Meti'ouicmis mclicitlosus, Blackburn. 



Anchotnemts nuiiciilosns Blackburn, Ent. Mo. Mag. xiv. 1877, p. 146. 



I know so little of this species that I scarcely like to remark on it. According to 

 two specimens sent me by Mr Blackburn it is a small species of depressed black, with 

 the margins of the thorax and elytra and the suture red, antennae and legs bright 

 yellow ; the tips of the elytra very little sinuate, and the striae not deep. Mr Perkins 

 has not met with the species ; a specimen he found in the Waianae mountains (2000 — 

 3000 ft., April 1892) comes near M. )ncticiilosiis, but I think is clearly not the same 

 species. Another specimen from Halemano is entirely yellow in colour, but may be a 

 variety of AI. meticulosus. 



Hab. Oahu. Under the bark of trees on the mountains ; not common (Blackburn).
