COLEOPTERA 



Baryneus, sfen. nov 



209 



Alae magnae, perfecte explicatae, metasternum elongatum. Tarsi posteriores 

 articulo quarto haud bilobato. Elytra striata, nullo inodo rugosa. 



This genus is established for Barypristns sJiarpi, Blackburn. It has the wings of 

 maximum size, and the metasternum correspondingly elongate, while the general shape 

 and build is that of a winged Anchomenid. From Colpodiscus it is separated by the 

 unlobed fourth tarsal joint (Plate VI. fig. 15). The other characters are those of 

 Bai-ypristiis. The thoracic margin is largely developed and there is a conspicuous seta 

 on the lateral margin, the hind angles being completely rounded. The sculpture of 

 the elytra is entirely destitute of peculiarity, the impressions on the ninth interstice 

 are small and numerous, and the basal margin well developed. 



Colpodes viacroptcinis Chaud. from New Zealand is in appearance similar to 

 Baryneus, but has sculptured tarsi and two thoracic setae on each side, as is usual in 

 Anchomenides.

Plate VI. fig. 2, individual with elytron and wing expanded. 



This is very distinct from Barypristus incendmrius on account of its shorter thorax 

 and more slender legs. It is intensely black in colour. The wings are perfectly 

 developed and are 16 mm. long, and 6 mm. broad in a specimen the elytra of which 

 are 9^ mm. long. 



Hab. Maui (Blackburn, Perkins): Haleakala, 3 — 5000ft. A small series was 

 found by Mr Perkins in April and May, 1894. The habits are the same as those of 

 Barypristns incendiarius in Hawaii. 



Colpodiscus Sharp. 



Colpodiscns'S)\\2LX^, Ent. Mo. Mag. xx. p. 217. 



Anchoniemis Incipctens Blackb. may be taken as the type of this genus. The 

 second species I reluctantly associated with it has the tarsi grooved, and belongs 

 therefore to a different division of the Anchomenides according to the system 1 have 

 here adopted (cf. Co/pocaccus). 



The ample wings, the strongly lobed foot (Plate VI. fig. 16), and the single thoracic 

 seta, make this a very easily recognised genus.
