Blackb., but this information will not be of much value to most 

 Coleopterists ; it is, however, in character Aery similar to the 

 puncturation of the common European Ips fevrugineus^ Fab., but 

 is very much closer, the whole upper surface being quite as closely 

 punctured as the head of Ips ferrugiiiPiiH. 



The " intermediate plate " on the under surface is moderately 

 large, and is equilaterally triangular in shape.

The following species is so near absolute agreement with Herr 

 Reitter's characters for this genus that I do not think it would 

 be desirable to give it a new generic name merely on the ground 

 of some slight discrepancies. These are that the mesosternum is 

 (not "scarcely," but) not carinate, and that the prosternum is not 

 prolonged behind the front coxae in a distinct process. The 

 structure of the prosternum is not mentioned in Herr Reitter's 

 diagnosis of the genus, but from its being placed near ^EtJiina 

 and Lasiodactylus the presence may be inferred of at least the 

 "small pin-point-like process" attributed to those two. This, 

 however, I have not been able to detect in the example before 

 me, the prosternum being bent down behind the anterior cox^e 

 almost exactly as in Soro7iia. It is possible, however, that this 

 may be the case in Idcethina, as otherwise it is difficult to under- 

 stand why its author has separated it from Lasiodadyhis, as all 

 the characters given are also attributed to Lasiodactylus, except 

 the labrum being very short, and this latter character seems a 

 very feeble one on which to found a genus. The claws of Id(Hhina 

 are said to be '' simple;" the claws of the specimen before me are 

 certainly not dentate, but they are slightly dilated at the base — 

 not, however, to an extent that seems inconsistent with their 

 being called simple. It is possible that Herr Reitter, if he saw 

 this insect, would give it a new generic name. I may add that 

 the eyes of this insect are more strongly and coarsely granulate 

 than those of any other Nitidulid known to me. The piece of 

 the undersurface which I have called the " intermediate plate" 

 {vide p. 102) is very large and well defined, almost as in 

 MeJigetlies.
