cem inordinatis), laete rufo-fcestaceis, plaga communi magna a 

 basi fere ad medium extensa, superfioiem fere amplectente, apice 

 angulatim emarginata, nigra, caeruleo tincta, ornatis. 

 Long. 5-7 lin. 



Hah. Manilla, Celebes. 



Vertex and front shining, impunetate; encarpse separated 

 from the front by a deep impression, thickened, sublimate ; 

 antennas more than half the length of the body, the second 

 joint very short, moniliform, the third one half longer than 

 the second. Thorax nearly three times as broad as long; 

 sides parallel, sinuate from the base to beyond the middle, 

 slightly converging at the apex, the anterior angles obtuse, 

 the hinder ones produced, acute ; disk finely punctured, im- 

 pressed on the median line with a shallow, ill-defined, longitu- 

 dinal fovea, broadly and deeply transversely excavated on 

 either side. Elytra much broader than the thorax, oblong, 

 not dilated posteriorly ; moderately convex, the humeral 

 callus thickened, the basilar space raised and well defined, 

 being bounded on its outer side and behind by a deep groove, 

 the hinder portion of which is strongly curved ; surface 

 minutely punctured ; in the female these punctures are placed 

 irregularly in longitudinal rows, which are most distinct on the 

 middle disk ; in the male the rows are obsolete and the punctures 

 placed without order over the entire disk ; the large bluish- 

 black patch covers nearly the whole of the basal half of the 

 elytra, its base extending entirely across the disk, its sides 

 slightly contracted posteriorly, leaving a narrow rufo- testaceous 

 line between its outer edge and the lateral margin of the 

 elytron. 



Haplosonyx Mouhoti. 



H. anguste oblongus, postico paullo ampliatus, convexus, rufo-ful- 

 vus, nitidus, antennis (basi exceptis) nigris, articulo ultimo 

 sordide albido ; thoraco transversim sulcato, distincte punctato ; 

 elytris sat crebre et fortitcr punctatis, obscure metallico-purpu- 

 reis, a vix pone medium ad apicem rufo-fulvis. 



Long. 4 Hn. 



Hah. Siam, Cambodia. Collected by the late M. Mouhot. 



Vertex and front smooth, impunetate, encarpse thickened, 

 transverse, separated from the front by a deep depression ; 

 antennas four fifths the length of the body, filiform, the se- 

 cond and third joints very short, equal, the three lower joints 

 obscure rufo-fulvous, the apical one dirty white. Thorax 

 more than twice as broad as long ; sides straight and parallel 

 from the base to beyond the middle, thence rounded and con- 

 verging to the apex ; the hinder angles acute, the anterior
