42 MANDIBULATA. — COLEOPTERA. 



CI. cylindrica. De Jean. — Dy. cylindricus. Steph. Catal. No.bO, 



Also allied to Dy. nitidus, but narrower and more cylindric than politus : it is of 

 a deeper but less brilliant bronze above : the thorax is, as in the last species, 

 a little less globose, more elongate, with the longitudinal line less evident : 

 the elytra are more elongated and nearly parallel ; and their striae are deeply 

 impressed, and very strongly punctate : the anterior tibiae are more strongly 

 bidenticulated than in Dy. nitidus. 



I have one specimen agreeing with the above, which was found 

 at Swansea. 



Sp. 5. arenosus. Supra ferriigineo-CBneus, tibiis anticis opice hispi- 

 nosis, extrorsum obsolete bidenticulatis ; elytris ovatis, striato-punc- 

 tatis. (Long. corp. 2 lin.) 



Dy. arenosus? Leach MSS. — Steph. Catal. No. 51. 



This approaches in form to the following, but it is considerably larger: its 

 colour (which may probably arise from immaturity) is of a ferruginous- 

 bronze, with the legs, antennae, and palpi pale : the thorax is larger, less glo- 

 bular than in the preceding species, and the elytra are more deeply punctato- 

 striated. 



There is a specimen in the British Museum bearing the above 

 MSS. name, which appears to correspond with one whicli is in my 

 collection, and from which the above characters are drawn. My 

 specimen was obtained from an unknown source. 



Sp. 6. digitatus ? Supra ceneus^ tibiis anticis apice bispinosis {spina 

 interna arcuatd) extrorsum valde bidenticulatis; elytris ovatis 

 punctato-striatis. (Long. corp. 2 lin.) 



CI. digitata? De Jean. — Dy. digitatus. Steph. Catal. No. 52. 



The form and size of Dy. thoracicus, but of a less brilliant bronze : the longi- 

 tudinal line on the thorax is rather deeper : the striae on the elytra are more 

 evident and deeply punctated : the interior spine, which terminates the an- 

 terior tibiae, is recurved at its extremity, and the other denticulations of the 

 tibiae are more distinct than in the other species. 



Of this insect I possess a single specimen, which accords with 

 De Jean's description, excepting that the recurved spine is less 

 evident. It may probably be a monstrosity of some other species ; 

 but I know not to which it can be referred. 



Sp. 7. seneus. Supra census, tibiis anticis apice bispinosis, ex- 

 trorsum bidenticulatis; elytris oblongo-ovatis, striato-punctatis. 

 (Long. corp. H — If lin.)
