SCOTT— COLEOPTERA, LAMELLICORNIA AND ADEPHAGA 245 



really got in Praslin by Alluaud is the var. seychellensis, just described above. The real 

 tenuilineata W. Horn is a synonym of var. perplexa Dejean. 



Loc. Seychelles : Praslin ; in hot sunshine on bare red subsoil, paths behind Grande 

 Anse, etc., XL 1908; 1905; previously obtained in Praslin by Alluaud: Mahe, 1909, 

 1 specimen. Farquhar Atoll : 1 $, 1905. 



Carabidse. 



Ophionea Klug, 1821. 



Bedel (Bull. Soc. ent. France, p. 72, 1910) states that Casnonia Latreille and Dejean 

 (1822) is exactly synonymous with Ophionea Klug (1821) ; but that Casnoidea Castelnau 

 (1835) can be provisionally retained as a distinct genus, though differing from Ophionea 

 only in having the 4th joints of the tarsi bifid, while in Ophionea they are not bifid. 

 Casnonia Latreille is given by Alluaud in his Liste des Coleopteres de la Region 

 Malgache, p. 38, as synonymous with Colliuris Degeer (1774), but Bedel {I.e.) considers 

 that Ophionea ( = Casnonia) should be kept separate from Colliuris, at any rate for the 

 present. 



27. Ophionea sp. 



A single specimen belonging to a species not represented in the collections of the 

 British Museum or (as M. Lesne has informed me) of the Paris Museum. There are 

 however many described species which I have been unable to see, and I have thought it 

 best not to make this single specimen a new species. The following is a description : 



Length 6^ mm. Head and thorax strongly shining, dark blue ; labrum and 

 mandibles dark reddish-brown, palpi testaceous, antennae with joints 1 — 3 and the base 

 of joint 4 testaceous, the rest of joint 4 and joints 5 — 11 darker; legs testaceous; elytra 

 pitchy-brownish, testaceous at the apex, shining, with a slight metallic bluish reflection in 

 front. Head smooth and impunctate but with some very fine transverse striolaj, rhom- 

 boidal, the sides behind the eyes sloping in towards the neck, the hind angles rounded 

 off; the neck is constricted but not prolonged or excessively narrow. Thorax slightly 

 longer than broad, narrowed in front and with the anterior angles rounded off, somewhat 

 narrowed also at the base, with sides rounded and slightly sinuate before the posterior 

 angles, which are almost right angles ; surface smooth and impunctate in front, with faint 

 transverse striolse and a distinct median longitudinal line, rather closely and subrugosely 

 punctured at the base. Elytra at the base twice as wide as the base of the thorax, or 

 more, each with 8 strife bearing series of punctures becoming obsolete towards the apex, 

 and with a very short series of, punctures at the base between the suture and the first 

 stria ; interstices smooth and flat. The elytra ai'e nearly parallel-sided and obliquely 

 • subtruncate behind : I can see no trace on them of seriate tactile hairs such as are 

 mentioned by Bedel {op. cit. p. 71) as occurring in certain members of the genus. 



Loc. Seychelles: Mah^, 1907 (Thomasset).
