Mr. R. Kidston on some Fossil Plants. 473 



sub-bifoveolata ; pronoto dense punctato, 6-costulato, margin e 

 non-elevato ; elytris costis 6 alternatim elevatis, intervallis bi- 

 crenato-carinulatis, insterstitiis punctulatis ; propygidio grosse 

 punctato, in medio subelovato ; prosterno lato, basi sinuato ; 

 mesosterno bisinuato, metasterno in medio subsulcato. L. 2^ mill. 



Hab. Amurland (Ckristoph). 



This species has the thoracic margin and costae as in exa- 

 ratus, but the punctuation of the thorax is after the manner 

 of sulcatus, but more dense. The elytra also are sculptured 

 closely to the pattern of exaratus, but the punctures are not 

 strigose. Between the second and third costee at the base of 

 each elytron there is a large and very deep sulcus, as is often 

 the case in sulcatus. 



Ontlwjjhilus hova, n. sp. 



Ovalis,subconvexus,niger,nitidus ; antennarum clava tarsisque flavis, 

 fronte inaequaliter impressa ; pronoto ocellato -punctato, margine 

 magis dilatato, stria interna parallela fortiter elevata ; elytris sutura 

 et 4 costis elevatis, intervallis biseriatim punctatis, cum punctu- 

 lorum linea intermedia ; prosterno lateraliter marginato, basi 

 sinuato ; mesosterno bisinuato ; metasterno profunde bifoveolato, 

 in medio sulcato. L. 1| mill. 



Hab. Madagascar (R a fray). 



This species is very roughly sculptured and relatively longer 

 than any other known species. It is allied to costipennis and 

 9-costatus } from which the size, absence of thoracic carinaa. 

 and the deep foveae and sulcus in the metasternum, thus "|"> 

 will distinguish it. It is slightly setose, and is probably a 

 species which resides under bark like hispidus and arboreus. 



XLIV. — Notes on some Fossil Plants collected by Mr. R. 

 Dunlop, Airdrte, from the Lanarkshire Coal-field. By 

 Robert Kidston, F.G.S.* 



Through the kindness of Mr. Dunlop I have had the oppor- 

 tunity of examining the fossil plants collected by him from 

 several localities in the Lanarkshire Coal-field. The annexed 

 list of species, compiled from this collection, though of con- 

 siderable interest, must not be regarded as a complete repre- 

 sentation of the Carboniferous fossil flora of this district; but 

 it contains one or two species which have not been previously
