Seychelles and Rangoon. 21 



figures of the latter with Matthews's illustrations of Cory, 

 tophus. 



Dauhania is dedicated to Monsieur and Madame Edouard 

 Dauban, owners of the island of Silhouette, Seychelles. 



10. Dauhania sei/chellarum, sp. n. 

 (PI. I. fig. 18 ; PI. ill. tig.s. 19, 21-24.) 



Nitida, supra glabra, prothorace rufo, elytris piceo-nigris ad apicem 

 parum dilutioribus, ore antenuis pedibus rufo-testaceis, aiiteii- 

 narum clavis iufuscatis ; prothorace subtiliter obsolete puactato, 

 elytris sat dense strigoso-punctatis. 



Long. Corp. 0'8 mm. 



With the characters of the genus. Colour: thorax red, 

 anterior margin paler, tiauslucent ; scutelluni and elytra 

 pitchy black, the latter diluter towards the apex ; underside 

 reddish brown ; legs, mouth, and autennse reddish testaceous, 

 the antenuEe with clubs infuscate. Sculpture &c. : disc of 

 thorax finely and obsoletely punctured; elytra closely punc- 

 tured, punctures separated by more than their own diameter, 

 produced into channels or striae, the general direction of 

 which is longitudinal, though near the suture they become 

 oblique ; though quite distinct, these striai are not very deep, 

 and under high lights sometimes only the actual punctures 

 are visible. Fygidium finely pubescent. Metasternum with 

 surface finely alutaceous at the sides, smooth in tlie middle, 

 and with punctuation and pubescence very scanty ; in one 

 specimen examined it is bare of pubescence in the middle, 

 the first abdominal segment is also nearly bare and has a 

 median longitudinal depression ; in another example this 

 depression is absent, the segment is more pubescent, and the 

 metasternum has some scanty pubescence in the middle in 

 front. These differences possibly may be in part sexual 

 (cf . Rhypohias, p. 26) . The other ventral segments are finely 

 punctured and pubescent. 



This species is quite distinct in general appearance from all 

 other Seychelles Corylophida3 by its minute size, strigosely 

 punctured elytra, &c. No species of any genus in Matthews's 

 collection superficially resembles it. Oligarthrum icater- 

 housei is quite different, being larger, unieolorous blackish, 

 with hind angles of thorax less produced and elytral punc- 

 tures not drawn out into striola?.
