joints of equal length, second joint shorter; thorax about twice and 

 a half broader than long, the sides strongly rounded, with a narrow 

 reflexed margin, anterior angles slightly pointed, posterior ones 

 obtuse, the surface entirely impunctate, scutellum broad, elytra 

 extremely finely and rather remotely punctured, the apical mar- 

 gins furnished with single hairs, posterior tibise deeply sulcate, 

 the first joint of their tarsi nearly as long as the foUowing joints 

 together. 



Much narrower and less convex than S. nigricornis Bal y the type 

 of which I huve compared, the head without the foveae at the vertex, 

 the antennae with only the basai two joints fulvous and the third 

 and following joints equal (in S. nigricornis, the antennae are 

 much more robust and the second and third joints are equal.) 



SEBiETHE NIGRITARSIS sp. n. 



Above reddish fulvous, below paler, antennse (the basai three 

 joints excepted) and the tarsi black, thorax impunctate, elytra 

 finely and closely punctured. 



Length 31/2mill. 



Oblong-ovate, the head impunctate, frontal élévations transverse, 

 labrum fulvous, antennse rather long, black, the lower three joints 

 fulvous, second and third joint nearly equal, rather robust, the 

 rest longer, of equal length, stout; thorax more than twice as broad 

 as long, the sides rounded, the anterior angles slightly produced 

 outwards, latéral margins narrowly reflexed, the dise impunctate 

 or with a few very minute punctures nearthe base, scutellum broad, 

 rounded at the apex ; elytra slightly widened towards the middle, 

 with a narrow margin, minutely and closely punctured, their 

 epipleurse broad and concave, below pale fulvous, the tibise 

 deeply sulcate, the metatarsus of the posterior legs elongate, ail the 

 tarsi black. 



At once distinguished by the black tarsi and comparatively 

 small size from its allies. 



SEB.^THE BREVICOLLIS sp. n. 



Pale fulvous, antennse (the basai three joints excepted) black, 

 thorax impunctate, twice as broad as long, elytra oblong-ovate, 

 minutely punctured. 



Length 6 miJl. 



Head impunctate, frontal élévations transversely subquadrate, 

 carina acute, antenose extending beyond the middle of the elytra, 

 black, the basai three joints fulvous, third joint slightly longer
