418 On neiv Coleoptera from Madagascar. 



Logisticus obscurus, n. sp. 



Fusco-niger, subtiliter griseo-pubescens ; rostro vix longiore quam 

 latiore ; elytris leviter convexis, haud costatis, apice ipso truncato, 

 angulo externo producto. 2 • 



Long. 8i lin. 



This has almost completely the form of L. simplex, but is 

 of a uniform blackish-fuscous colour, the antennas, tibiae, and 

 tarsi brownish. The rostrum is not quite so short (not so 

 long as in rostratus) ; and the eyes are almost contiguous 

 below, moderately separated above. The apex of the elytron 

 is a little truncate, with the external angle distinctly pro- 

 duced. 



Hah. Antananarivo (Mr. Kingdon). 



Appedesis, n. gen. 



Antennae very slender, widely separated. Eyes promi- 

 nent posteriorly, not supported behind by any cheek. Thorax 

 ■evenly convex, arcuately narrowed anteriorly in front of the 

 middle, with no lateral tubercle. Elytra not costate, mode- 

 rately narrowed posteriorly, slightly truncate at the apex. 

 Intermediate as well as anterior coxae very prominent. Poste- 

 rior tarsi not very elongate, the third joint bilobed. 



The general appearance of the species for which I propose 

 this genus is that of some species of Leptura ; but the slender 

 antenna?, the eyes not supported behind by any cheek, and 

 the shorter tarsi induce me to separate it. The posterior 

 tarsi are especially relatively less long, less compressed, 

 and the third joint is broader, strongly bilobed. It should be 

 placed before Leptura. 



Appedesis vidua, n. sp. 



Sordide flava ; capite abdomineque nigris, tborace ferrugineo-rufo, 

 scuteDo piceo ; elytris fusco-nigris, fascia lata basali utrinque 

 vittam elongatam emittente sordide flava. 



Long. 3| lin. 



Head black, clothed with greyish-yellow pile, very closely 

 and finely punctured ; flat in front, the antennal tubercles 

 depressed. Eyes finely granular, completely free and pro- 

 minent posteriorly. Thorax dull red, as long as broad, gently 

 convex, with very short yellowish pile, densely and rather finely 

 punctured, a little narrowed in front of the middle, subparallel 

 posteriorly, the extreme base margined with black. Elytra 

 about one third broader than the thorax, moderately narrowed 

 posteriorly, slightly truncate at the apex, clothed with very 

 short, not very dense, yellow pile ; moderately, thickly, and
