and species of Cryptoceplialidce. 29 



paullo ampllatum, margine antico paullo producto, oblique 

 deflexo, margine postico bilobato. 



The type of this new genus is a $ , the $ being unknown 

 to me, but tlie dilatation of the intermediate joints of the 

 antenna (so unusual in the female sex) justifies, in my 

 opinion, its separation from Idiocephcda, and its erection 

 into a distinct generic form. 



Chariderma pulchella, 



Oblongo-elongata, laste falva, nitida, antennis (annulo 

 albido ante apicem excepto), pectore lateribus et postice, 

 abdomine, tibiis tarsisque nigris ; thorace convexo, utrinque 

 oblique sulcato et pone sulcum leviter elevato, fere irn- 

 punctato, vitta mediali et utrinque macula rotundata 

 prope marginem posita nigris; scutello basi nigro-margi- 

 nato; elytris punctato-striatis, utrisque macula oblonga, 

 supra Galium humerale posita, nigra, instructis. 



Long. 41 lin. 



Hob. — Western Australia. 



Face excavated between the eyes ; vertex finely rugose- 

 punctate ; clypeus trigonate ; antennas equal to the body in 

 length, black, the eighth and the ninth joints (the apex of 

 the latter excepted) yellowish -white ; the basal one incras- 

 sate, subclavate, the second short, the third to the sixth 

 joints compressed and dilated ; the third elongate, gra- 

 dually increasing in width on either side nearly to the 

 apex ; the fourth and fifth equal in length, narrowed at 

 the base, each shorter than the third, the sixth still shorter, 

 less broadly dilated ; the seventh two-thirds the length of 

 the preceding joint, only moderately thickened and com- 

 pressed; four following joints cylindrical, nearly equal in 

 length, each shorter than the seventh. Thorax twice as 

 broad at the base as long ; sides slightly diverging at the 

 extreme base, thence obliquely converging to the apex, 

 lateral margin entire, sinuate before the middle; upper 

 surface transversely convex, obliquely impressed on either 

 side behind the middle, the space behind the sulcate por- 

 tion thickened. Scutellum Avedge-shaped, its apex trun- 

 cate, its base bilobate and overlapping the l)asal lobe of 

 the thorax ; the basal border narrowly edged with black. 

 Elytra slightly broader than the thorax, punctate-striate, 

 the interspaces smooth, impunctate.
