318 Mr. J. S. Baly's descriptions of new genera 



parallel at the extreme base, thence rounded and con- 

 verging to the apex, anterior angles thickened, obtuse ; 

 above convex, granulose, finely and subremotely punc- 

 tured. Elytra soldered together at the suture, broader 

 than the thorax, oval, truncate at the base ; convex, 

 regularly punctate-striate, the punctures shallow, but 

 much larger than those on the thorax ; interspaces plane, 

 granulose. 



Genus Xenidea, Baly. 

 Xenidea Wallacei. 



Anguste ovata, convexa, picea, nitida, pedibus anticis 

 quatuor antennisque obscure fulvis ; thorace minute, sub- 

 crebre punctato ; elytris metallico-violaceis, piceo-tinctis, 

 distincte punctato-striatis ; interspatiis planis, externis 

 convexiusculis. 



Long. 1^ lin. Hah. — Sulu Islands, New Guinea. 



Head trigonate, scarcely longer than broad ; vertex and 

 front shining, impunctate ; frontal grooves oblique, ex- 

 tending downwards from the upper margin of the eyes to 

 the carina ; the latter strongly raised, rather broader and 

 less compressed than in X. purpureipennis ; antennse more 

 than half the length of the body. Thorax twice as broad 

 as long ; sides straight, faintly bisinuate, anterior angles 

 obliquely truncate ; upper surface convex, finely but 

 rather closely punctured. Elytra broader than the 

 thorax, oblong-ovate, slightly attenuated towards the 

 apex, distinctly punctate-striate, interspaces impunctate. 



Xenidea purpureipennis. 



Ovata, convexa, rufo-testacea, nitida, pleuris, tarsis 

 tibiisque posticis piceis ; antennis nigris, articulis basali- 

 bus fulvis, 9mo et lOmo flavo-albidis ; femoribus posticis 

 elytrisque metallico-purpureis ; his regulariter punctato- 

 striatis, interspatiis convexiusculis, ad latera et ad apicem 

 convexis ; thorace lasvi, remote, tenuissime punctato. 



Long. 2 lin. Hab. — New Guinea (Dorey). 



Head triangular, not longer than broad ; vertex and 

 front smooth, impunctate ; encarpae obsolete ; carina 

 strongly raised, linear; frontal grooves bordering the 

 upper half of the inner margin of the eye, then abruptly 

 curving inwards, nearly at right angles, to the carina; 

 antennae slightly more than half the length of the body.
