168 Mr, G. C. Champion on Coleoptera from 



like its Paleearctic allies. The European Mijctei'us curcu- 

 lionoides F., has a similar tuft of hairs on the second ventral 

 segment in the male. 



Fam. (EdemeridsB. 



One species of this fainily is quoted by Kolbe as having 

 been recorded from the Seychelles by Fairmaire in 1893, 

 but no name was given ; the insect in question is doubtless 

 one of those subsequently described by the French author *. 



OXACIS. 



O.racis, Lecoute, New Species Coleopt. p. 165 (1866) ; Leconte & 

 Horn, Class. Coleopt. N. Am. p. 405 (1883); Champion, Biol. 

 Centr.-Am., Coleopt. iv. 2, p. 149, and Trans. Eut. iSoc. Lond. 1896, 

 p. 39. 



The insects placed under this genus have the mandibles 

 nncleft at the apex, the right one, at most, with a short 

 tooth before the tip. Amongst the ten species of Ananca 

 recorded by Fairmaire from Madagascar or the Seychelles 

 two, at least, A. gi'isescens and A. lineoluy belong to Oxacis 

 as here understood, and Lagria livida, F. (selected by 

 Semenow as the type of Sessinia, Pasc), from Tahiti, is 

 congeneric with it. Fairmaire notes the extreme rarity of 

 the males of some of these CEdemerids. 



6. Oxacis grisescens. (Text-fig. 1, cT genital armature.) 

 Ananca grisescens, Fairm. Ann. Soc. Eut. Belg. xli. p. 119 (1897). 



Elongate, robust, pale testaceous, the eyes and the tips of 

 the mandibles black, subopaque, the anterior portion of the 

 head shining, thickly clothed with very fine pallid pubes- 

 cence. Head above and between the eyes densely, finely 

 punctate, the punctuation becoming coarser and diffuse on 

 the anterior half, the epistoma rather long; eyes very large; 

 left mandible simple, right mandible toothed before the tip ; 

 antennae nearly as long as the body in cT? a little shorter 

 iu $ , joint 3 distinctly longer than 4, 11 shorter than 10 

 and feebly constricted at the middle. Prothorax oblong- 

 subcordate, densely, finely punctate, obsoletely, interruptedly 

 canaliculate down themiddle, the shallow groove terminating 

 in a deeper, transverse, foveiform depression before the base, 

 the disc transversely flattened or depressed towards the apex, 



* Fairmaire also mentions (Bull. Soc. Eut. Fr. 1893, p. xcix) a Can- 

 tharid and a lihipiphorid from the Seychelles, but no n.imes are given.
