punctulato, antice medio impressione rotundata rugosa et utrinque 

 plaga parva rugosa notato, lateribus leviter rotundatis ; elytris 

 thorace baud latioribus, postice ampliatis, fortiter lineato-punc- 

 tatis ; pedibus rufo-piceis. Long. 11^ lin., lat. 5J lin. 



The elytra are covered with rather large horseshoe punc- 

 tures, among which may be traced the usual two pairs of 

 punctured lines ; the surface between the large punctures has 

 small punctures scattered here and there. 



Malacodermata. 



MelyridsB. 



Malthacodes, gen. nov. 



Maxillae with two lobes, membranous, the internal smaller 

 and narrower than the external ; apical joint of the maxillary 

 palpi strongly securiform ; mandibles bifid at the apex. An- 

 tennae with the first joint elongate, the second smaller and 

 shorter, the third a little longer than the second but not so 

 long as the first ; the fourth to tenth about as broad as long, 

 narrowed at their base ; the eleventh oblong. Eyes pro- 

 minent. Thorax transverse, broadest at the base. Elytra 

 scarcely broader than the thorax and' twice and a half as 

 long. Tarsi with the basal joint a little elongate, second 

 to fourth joints subequal, shorter than the first ; claws with 

 a membranous lobe beneath each. Body pubescent. 



The species upon which this genus is founded resembles 

 HaplocnemiSj but is of a shorter form, the head is short, and the 

 apical joint of the maxillary palpi is very strongly securiform. 

 Pehco2)horus is described as having the basal joint of the tarsi 

 very short, shorter than the second ; this I cannot apply to 

 the insect here described, or I should have placed it in that 

 genus. 



Mahhacodes pictus, sp. n. 



M. oblongus, leviter convexus, nigro-seneus, griseo-pubesoens ; an- 

 tennis nigris, articulo basali piceo ; tborace longitudine duplo 

 latiore, sat crebre subtihter punctato, lateribus arcuatis, tenuissime 

 flavo raarginatis, basi utrinque leviter sinuato ; elytris thorace vix 

 latioribus at 2^ longioribus, crebre sat fortiter punctatis, fasciis 

 duabus flexuosis rufo-testaceis ; femoribus piceis, tibiis tarsisque 

 pallide testaceis. Long. 1| lin., lat. | lin. 



Ptinidse. 



Xylodes, gen. nov. 



General form nearly that oi Hedohia. Antennae rather thick, 

 not approximate at the base ; the basal joint oblong, the second
