tification in assuming that the specimen bearing the type label of 

 olivaceus in the LeConte collection is not truly the type of that 

 species, which, as I stated in my former revision, is indistinguishable 

 from the type of punctatus, especially when this fact is corroborated 

 by LeConte himself in his latest table of Limnichus, although this 

 in itself is not conclusive evidence, as the author was mistaken in 

 uniting his obscurus with ater. There can be no doubt therefore 

 that the species described above under the name huronicus is valid 

 and distinct from punctatus; virginicus is closely allied to punctatus 

 but seems to be distinct. 



Though almost certainly identical and following the distribution 

 of many species, such as Limnichoderus naviculatus and Physemus 

 minutus, nebulosus, as described above from central Texas speci- 

 mens, may possibly be different specifically from the San Bernardino 

 type; but the description of LeConte is ambiguous and valueless 

 in totality, being simply: Body beneath densely and coarsely 

 punctured, smaller and more elongate than punctatus; pubescence 

 above brownish, mottled with silvery-white. 1.5 mm. San 

 Bernardino, Cal. In case of conflict it might be contended that 

 these few words could not be held to be proper publication, if in 

 doing this we did not have to rule out a large proportion of the 

 species of Fabricius and some other early authors as well. Eu- 

 limnichus confertus Shp., is evidently very closely allied to aus- 

 tinianus and E. admirandus Shp., from Teapa, may be identical 



with nebulosus Lee. 



Eulimnichus Csy. 



Limnichus (subgen. Eulimnichus Csy.), olim. 

 The species of this genus are rather more numerous perhaps than 

 those of Limnichites, and individuals of the various species are 

 apparently much more abundant and less local as a rule. The trans- 

 verse line of the pronotum, when visible, never has the nature of a 

 swelling of the surface or a series of detached punctures, but is 

 formed by a simple intensification of the minute reticulation of the 

 surface and is rendered evident only by its consequently slightly 

 greater opacity; the line is always very fine and feebly marked, 

 frequently wholly wanting and would never be noticed if not 

 particularly searched for in connection with the transverse series 

 of punctures, frequently notably evident in the preceding genus
