288 Mr. WATERiiousii's Descriptions of 



This species is remarkable for its coloration, wliicli somewhat 

 resembles that of Antichira cincta. It is almost entirely desti- 

 tute of pubescence on the upperside. Thorax moderately convex, 

 shining, the disc generally castaneous and smooth, there are a 

 few punctures scattered over the sides, and there is an irregular 

 triangular patch of rather strong punctures on each side of 

 the base. Scutellum with three or four punctiires on each side. 

 Elytra with the three usual costa3 ill defined, the interstices 

 sparingly, finely and irregularly punctured ; each elytron has 

 a pale pitchy stripe commencing in the middle of the base and 

 reaching nearly to the apex (leaving a quadrangular scutellar 

 patch and the suture black) ; a second stripe commences below 

 the shoulder and does not quite reach the sub-apical callosity, 

 this stripe is frequently interrupted in the middle, apex with 

 minute tubercles. Antennae pitchy. 



$ Head smooth, clypeus with a few distinct punctures ; fifth 

 abdominal segment smooth. 



$ Head with moderately close distinct punctures behind, 

 near the eyes, and some fine punctuation along the frout 

 margin ; clypeus finely and rather closely punctured : fiftli 

 abdominal segment densely and finely rugulose below. 



Adoretus albosetosus, n. sp. 



Niger, ?eneo-purpurascens, nitidus, la^vis ; thorace fortiter 

 transverso, margin e basali utrinque parce punctato ; elytris 

 oblongis, subtiliter punctulatis, hand costulatis, infra scutelUim 

 et utrinque leviter impressis, ad apicem declivis, setis nonnullis 

 albidis ornatis ; antennis femoribusque anticis pallide piceis : 

 femoribus posticis maximis, subtus ad apicem fortiter calcaratis ; 

 tibiis posticis crassis, curvatis. Long. S^ lin., lat. lin. 



This species is so remarkable that I at first thought it Avould 

 be necessary to propose a ncAv genus for its reception. I think, 

 however, that as the peculiarity rests mainly in the structure 

 of the posterior legs which may be only a sexual character, it 

 will be better to wait imtil the sexes are knoAvn. Its robust 

 convex form, the entire absence of costaj on the elytra (which 

 appear smooth unless examined with a lens), and the Avhite stifE 

 bristles (which are j)ointed at their apex) on the elytra give 

 the species a marked character in the genus Adoretus. The 

 jDOSterior 00x03 are produced posteriorly into a spur. The apex 

 of the posterior tibiae is jiroduced beloAV to about the middle of 

 the fifth tarsal joint.
