Ilastododera? simplicicollis^ sp. n. 



M. later-ali similis, sed differt prothorace absque tubercnlis ; capite 



antice plus elongat.o ; pedibus anteimisque gracilioribus. 

 Long. 18, lat. 5^ mm. 



Ilab. Imeritia Mountains. 



The chief structural character by which this species could 

 . be separated from Mastododera is the absence of tubercles 

 from the prothorax. The latter is rounded at the sides, feebly 

 dilated in the middle, and narrowly constricted at the base ; 

 it is convex aliove, with evidence of a feeble groove or 

 depression along the middle of the disk. The legs are elon- 

 gate and rather slender, the posterior femora reach to the 

 apex of the elytra, and the last joint of the posterior tarsus is 

 longer than the three succeeding joints combined. 



The species is smaller and narrower than M. lateralis^ 

 Gudr., but is coloured in almost exactly the same way. The 

 lateral fulvous band of the elytra is, however, narrower and 

 stops short before reaching the apex. 



Glaucytes basalts, sp. n. 



Niger ; capite supra prothoraceque dense punctatis ; elytris minus 

 dense punctatis, fuaco-violaceis basi rufo-testaceis, vitta angusta 

 suturali griseo-pubescente, apicibus truncatis, quadridentatis ; 

 capite fronte vittaque utrinque, thorace subtus, et vitta utrinque 

 abdominis argenteo-griseo-pubescentibus. 



Long. 12-15 mm. 



Nab. Fianarantsoa, Imerina Mountains. 



This species has a strong resemblance to G. humerah's, 

 Buq., but is more elongated ; the prothorax is a little more 

 strongly and more thickly punctured, and has no silky, white 

 vitta on each side. The elytra are brownish rather than blue 

 in colour. 



In the male specimen, from the Imerina Mountains, the 

 antenna sui-pass the apex of the elytra by about the last two 

 or three joints. In the females they do not reach to the apex 

 of the elytra. 



Cedemon, gen. nov. 



Head moderately concave between the antennal tubercles. 

 Front rectangular. Eyes emarginate, coarsely faceted, with 

 the lower lobes longer than broad, rounded below. Antennai 

 a little longer than the body in the male, barely reaching 

 to the apex o£ the elytra in the female, sub(iliform and
