BEETLES EEOM CENTEAL AMEBICA. 131 



Mas clypeo apice prolongato et recurvato, processu apice transversim 



valde dilatato, genis dilatatis ; tibiis anterioribus sat elongatis. 

 Fern, clypeo apice acute bidentato, capite crebre sat fortiter punctate. 

 The autennse are reddish at the base, with the club infuscate. The 

 thorax is about 2f raillims. in length, and about 3i broad, and is of 

 a brilliant and shining brassy colour ; it is distinctly punctured at the 

 front angles, and more indistinctly about the middle ; but on the basal 

 portion the punctures are nearly absent. The elytra are smooth and 

 shining, and destitute of any punctuation or pubescence. The pygi- 

 dium is coarsely punctured, and bears scanty, short, stout, erect, pale 

 setffi. The metasternum in the middle is brassy, and is only sparingly 

 punctured ; the punctures are rather coarse on its lateral parts, but in- 

 distinct elsewhere ; the under surface is destitute of pubescence, except 

 that the apical segments of the hind body bear a few setae. The front 

 tibiae are distinctly quadridentate. 

 This is a very distinct species from any other I know ; but Von 

 Harold Las recently published, under the name of Onthophagus 

 sharpi, a species which appears to connect 0. tapirus with the 

 O. nasicornis group. 



Two other specimens found by Mr. Belt are of a bluish-black 

 colour, and have the clypeus in front produced into a short, broad, 

 simple process, and are probably a distinctly allied new species, 



IsoNYCHUS PICTUS, n. sp. Olivaceo-pubesccns, elytris maculis magnis 

 nigris, antennis rufis clava fusca, pygidio rufescente, pedibus nigris. 

 Long. 13 millim. 



Clypeus black, with a faint brassy tinge, without pubescence, but with a 

 few erect hairs, and bearing rough elevated tubercles instead of punc- 

 tures. Thorax entirely clothed with a yellowish olive pubescence, 

 which quite conceals the sculpture. Elytra also clothed with a dense 

 olivaceous pubescence, but with some very large and distinct black 

 spots, three along the suture and three at the side, more or less con- 

 fluent : the sculpture is concealed by the pubescence ; but they are 

 finely yet distinctly striated. 



In the male the front tibiae are slightly more slendei', and the club of the 

 antennae more elongate, than in the female, the pygidium is rather 

 shorter and is more closely punctured, the apical ventral segment is 

 impressed in the middle, the impression being roughly punctured 

 and free from pubescence. 



This striking species is probably allied to Isonychus maeulatus, 

 C. Waterhouse, from Medellin, in Columbia. 



Faula centralis, n. sp. Fusco-nigra, sericeo-opaca, pallide griseo- 

 setosa, antennis pedibusque rufescentibus ; thorace elytrisque fortiter 

 punctatis, illo area longitudinali, his lineis duabus elevatis.
