Ceaspedophoeus DEFLE5US, sp. D. — MediocrUer convexus, ?iiger, hrevlter se- 

 tosiis, palpis anfennis tibiis et tarsis rufo-piceis, elytris utrinque macuUs dnabus rufis, 

 interslilia 5 — 8 tegeiitibus, 1™" a hasi sat distanti, quadrata : caplte lata collo hand 

 depresso, toto grosse punctata, oculis valde prominentibus : thorace latissimo, lateri- 

 bus regulariter ab apice usque ad basin arcuatis sed versus apicem niayis conver- 

 genlibus, margine late explanato, nee refiexo, postice dejlcxo, angulis posticis 

 denticulo acuta, toto grosse discrete punctato .- elytris profunde punctato-striatis, 

 interstitiis minus defise et grossius punciulatis. Long. 17 mm.

The' form of the thorax is unlike that of any other species known 

 to me. It approaches nearest C.festivus (Klug), but is much broader 

 and less narrowed in front ; the side margins are more broadly 

 flattened even from the anterior angles, at first plane and behind 

 deflexed, with a corresponding convexity of the dorsal surface toM^ards 

 the hind angles. The elytra are oblong-ovate, narrower at the base 

 than the thorax at its widest part. The metathoracic episterna are 

 scarcely broader than long, and the ventral segments are crenulated 

 on their front margin. The apical joints of the palpi are not remark- 

 ably elongated at their exterior apex. 



Ceaspedophoeus abnoemis, sp.n. — Elongato-ablongus, mediocriter convexus, 

 hreviter setosiis, niger, elytris utrinque maculis tribus flavis, prima humerali apud 

 interstitium 8"™, secunda antemediana interstitia 4 — 6, tertiaque sub-apicnli in- 

 terstitia 4 — 8 tegenlibus : capite parvo, collo constricto, oculis valde prominentibus, 

 sulcis front alibus duobus profundis interspatioque valde convexo vertice sparsim 

 punctata : thorace fere sicut in C. brevicolli (Dcj.), sed lateribus antice lalius 

 rotundatis, transversa, lateribus arcuatis, angulis anticis late rotundatis, confertim 

 grassissime punctata : elytris relative valde elongatis, oblongis, lirajunde punctato- 

 striatis, stria 3»« apud maculam medianam fexuosa, interstitiis sat crebre punctatis. 



Long. 21 vim.

Unlike any other species, both in form and markings. Although 

 the terminal joint of the palpi is simply obliquely triangular ( ? ?) it 

 consorts better with the Craspedophori, in which that joint is greatly 

 prolonged at its outer angle, than with the Epicosmi. The labrum has 

 its front edge broadly emarginated : the antennae are long, with the 

 joints 4 — 9 much dilated and compressed. The metathoracic episterna 

 are very long, and the ventral segments crenulated on their anterior
