Herr Faust sent me no locality except " Trans-Caucasus." 



8. — Atracthelopliorus brevitarsis Kuw. 



One of the most distinct species of Halophorini. Eather short and convex, 

 vvitli minsually short legs and tarsi, small eyes, obsolete channel of the vertex, 

 and somewhat abbreviated wings. The upper surface rather strongly bronzed, 

 the thoracic grooves deep, the sculpture of' the intervals and punctuation not 

 rugose. Elytral punctuation moderate, interstices not convex. Length 3 mm. 

 Aedeagus (fig. G9) rather narrow, lateral and median lobes slender. 



Described from a co-type sent me by Kuwert from Bosnia. There 

 are three specimens from Herzei,'ovina in the Champion collection, 

 one of them is labelled " brevitarsis " in Kuwert's handwriting. 



Cyphelophorus Kuw. 



This is one of the most distinct of all the genera of Heio-phorim. 

 Its affinities are with Megemplewrus and TrichelopJwnis, between which 

 it should be placed. The true epipleuron is very small but is pubes- 

 cent ; the flank of the elytron becomes so greatly horizontal (and 

 visible from beneath) as to form a sort of false epipleuron, which is 

 very polished and shining, and makes therefore a strong contrast with 

 the true epipleuron. The sctilpture of the surface of this insect is 

 very peculiar, the strong tubercles of the elytra being of themselves 

 distinctive. Flexible hairs are apparently quite absent, except near 

 the movith-parts, there being even on the labial palpi, which are 

 minute, polished and shining, only one or two long hairs. 



The genus is certainly also allied to Atracthelopliorus, and shows 

 that it should be placed before, instead of after, Heloj^liorus. Although 

 Cyphelophorus tuberculatus can live in the water it is not truly aquatic, 

 but is really amphibious. According to Sahlberg it is fond of burned 

 places on the moors, with which its intense black colour corresponds. 

 It occurs in JST. America, and will probably be found to be a common 

 species in suitable sub-arctic localities when people know how to look 

 for it. 



1. — Gyphelophorus tuberculatus Gryll. 



The intense black colour and the tubercles of the elytra are 

 diagnostic of this species. It is the only one of the genus, and in 

 Europe is confined to the northern parts. In Britain the species occurs 

 on the moors of Scotland, Yorlcshire, and in the Manchester district. 

 Its distribution in America is unknown to me. The aedeagus (fig. 70, 

 pi. vi) is much like that of Trichelophorus.
