new Sjiecies of Ilistciicla}. 107 



Immcral carinate and extends beyond the middle, inner com- 

 j)lete but only carinate at the base ; the pygidia are evenly 

 and not densely punctured ; the prosternurn, stria sinuous 

 and well-marked, but abbreviated anteriorly before the suture, 

 keel distinctly punctured and obsoletely rugose ; the meso- 

 sternuMi, lateral fovea} are deep and circular and the margin 

 is wider than that of ii". Lejyrieuri, BLars. 



The species of Eretmotus are difficult to differentiate, but 

 the punctuation of the keel, the deep circular foveas in the 

 mesosternum, and the colour of the legs will distinguish the 

 above from the other two small Algerian species kuown, viz. 

 carinatus. Lew., and Leprieun\ Mars. 



Ilah. Yakouren, Algeria. 



There arc sixteen species of Eretmotus now known. 



Ontliophilus niponensis, sp. n. 



Ovatus, nigcr, subnitidus ; fronte Icvitcr concava, clypco quadrate ; 

 pronoto G-costato vix dense punctato; elytris 3-costatis, basi in 

 medio foveolatis ; pygidio in medio longitudinalitcr costato, dense 

 puuctato. 



L. 2J mill. 



Oval, black, somewhat shining ; the head slightly concave 

 between the eyes, the clypeus is nearly quadrate, being less 

 widened posteriorly than that of 0. glohulosus, 01. ; the 

 thorax is rather densely punctured, lateral margins narrowly 

 and slightly raised, surface 6-costate, outer costa short and 

 near tlie base, intermediate one tiiird longer and feebly oblique, 

 the two before the sculellum are short, parallel to each otiier, 

 and clearly separate ; the elytra are 3-costate, the interstices 

 with five fine carinules, and between the third costa and the 

 suture the outer carinules are crenate, at the base of the 

 elytra is a deep fovea between the second and third costce ; 

 the proi)ygidium is densely punctured, with a median longi- 

 tudinal carina. 



Tills species closely resembles 0. glohulosus, F., but it 

 differs by the clypeus being less wide at the base, by the 

 thoracic punctures being closer, smaller, and less deep, and 

 the elytral fovea is conspicuous and occupies the whole 

 breadtli of the interstice. As regards the Japanese species, 

 it is most similar to ostreatus, Lew., which is, however, much 

 larger, and the median thoracic costa3 have appendages 

 bcliind the neck.

 Paris and in my own collection.
