1 82 FAUNA HAWAIIENSIS 



Tribe PLATYPINI. 



Crossotarsus Chapuis. 



(i) Crossotarsus externedentatus Fairm. 



Crossotarsus externedentattis Fairmaire, Rev. Zool. 1S50, p. 51. 



Hab. Oahu ; Honolulu (Blackburn). — I cut a pair of this species out of a 

 hard trunk of Acacia koa, at an elevation of 1000 ft. in the northern part of the 

 Koolau range. 



Fam. ANTHRIBIDAE. 



The Anthribidae are very poorly represented in the islands, only three species 

 having occurred. Two of these species are at present not known from elsewhere, 

 and one of them constitutes a peculiar genus, but there is little doubt that all are foreign 

 insects, and will ultimately be found in other countries. 



Araeocerus Schonherr. 

 (i) Araeocerus fasciculatus De Geer. 



Ctirculio fasciculatics De Geer, Ins. v. 276, /. 16, fig. 2. 



Hab. Abundant all over the islands in the mountains. The large number of 

 constant varieties in markings, as well as the great variation in size of this species is 

 remarkable. 



(2) Araeocerzis const an s, sp. no v. 



A. fasciculato simillimus sed statura majore, totus dense griseo-pubescens, haud 

 variegatus, tarsis anterioribus t robustioribus, et tarsis % longioribus distinguendus. 

 Long, circa 5 mm. 



Very closely allied to A. fasciculatus, but larger than the larger examples of that 

 species, not varying much in size, and uniformly covered with dense grey pubescence. 

 In colour the integument is blackish and reddish fuscous, the antennae towards the 

 base and the tibiae are more or less red. When the pubescence is removed, the 

 pronotum is seen to be dull and very densely punctured, and the elytra bear each about 

 ten rows of very distinct and regular punctures, the interstices having a dense shallow 

 and very minute rugulose puncturation. Both sexes may be distinguished structurally 

 from A. fasciculatus by the thicker anterior tarsi, so that the t of the latter rather 

 resembles the % of the former, and these parts are longer in the % oi A. const an s. 



Hab. Hawaii, Kona ; on the coast ; found in the flowers of the white poppy.
