ing his tenth edition of the System, it is most fitting that the Polar 

 Hare of Southern Scandinavia should be made the type of the timidus 

 group, the Swedish Hares being those which would most naturally em- 

 body and form the source of his original diagnosis. 



The writer is now preparing a more compendious revision, with illus- 

 trations, of the New World representatives of the Lepus timidus group, 

 which will probably appear in a future number of the Proceedings of 

 the Academy of Natural Sciences of Philadelphia.

ENTOMOLOGY. 1 



On Certain Geophilidse Described by Meinert.— The Chilo- 

 poda of the Museum of Comparative Zoology were studied by Dr. 

 Meinert, and the results published in a paper entitled " Ifytietpoda 

 Musei Cantabrigensis." 2 Many new species were described, but as no 

 figures were given, identification is not in all cases easy, although the 

 descriptions are of considerable length. With reference to the Geo- 

 philidse, at least, there are certain misleading statements and unfortunate 

 omissions. During a recent visit to Cambridge I had the pleasure of 

 a very brief examination of the types of several of Dr. Meinert's species, 

 and some long-standing curiosity was satisfied. 



Oeophilus georgianus Meinert. 



According to Dr. Meinert this species has but a single pleural pore. 

 For some years past I have had specimens from the South which agreed 

 well with the description of this species, but had two pores. As this 

 character is a very constant one, my determination was not made with 

 confidence. The type of georgianus has, however, two large pores on 

 each side concealed under the last ventral plate, so that the Roomaly ii 

 disposed of. The pores are similar in structure and location to those of 

 G. rubens. 



Geophilus cephalicus Wood. 



The specimens described by Meinert, and previously by Wood as 

 cephalicus belong to G. rubens Say. I have examined the type in the 

 British Museum. It is the most common geophilid in the northeastern 

 states. 



Geophilus urbicm Meinert. 



No ventral pores could be made out. The sterna are uneven and 

 the whole animal is very hairy. The form of the body, the armature
