THE CANADIAN ENTOMOLOGIST. 211 



33. Nemobius fasciatus, De Geer. 



Abundant on Bear Island and occasionally met with elsewhere in the 

 Temagami District. The examples seen were mostly of rather small size. 

 No macropterous individuals were observed. 



34. JVemobius Carolinus, Scudd. 



Under this name I place the species which I described as JV. 

 angusticollis (Can. Ent., 36, 1904. p. 186). It is a very variable species, 

 and has apparently been described several times under different names. 

 A few years ago Prof. Morse drew my attention to the probable identity 

 of my JV. angusticollis with Scudder's JV. Caro/inus, which is not the 

 species usually quoted under that name. Since then I have seen the 

 specimens of JV. Carolinus in the Scudder collection, and although my 

 examination of these was brief and hurried, I am pretty well satisfied that 

 Professor Morse's suggestion was well-founded. My species, moreover, 

 agrees very well with Scudder's original description (Proc. Bost. Soc. Nat. 

 Hist, tq, March, 1877, p. 36^, except in this statement that the ovipositor 

 is longer than in JV. vittatus ( = JV. fasciatus, De G.), which is an obvious 

 error, as it is contrary to the measurements given in the description itself. 

 At the time I described the species as angusticollis, however, I had not 

 considered the possibility of my species being Carolinus, on account of 

 its not having been recognized as such by Dr. Scudder himself, and also 

 owing to the fact already mentioned, that the name Carolinus has been 

 employed to designate another species altogether. 



There are several other names which are apparently synonyms of 

 JV. Carolinus. The earliest of these is JV. (Anaxipha) septentrionalis, 

 Scudd. (Nat. Canad., IX, Oct., 1877, p. 292), which is given here to 

 replace JV. exiguus, Say, under which name a species of Nemobius was 

 described by Provancher in his "Petite Faune Entomologique du Canada" 

 (Nat. Canad., VIII, Feb., 1875, p. 61). There can be little doubt that 

 this description applies to the macropterous form of JV. Carolinus, which 

 I have taken occasionally in Ontario, but does not appear to have been 

 noticed elsewhere. The only point in which the description does not fit 

 Carolinus is in the statement, "Appendices abdominaux presque aussi 

 longs que le corps," which may have been an error of observation. 



JV. affinis, Beutenm., seems to me to be another synonym of JV. 

 Carolinus, as is probably also the species described by Blatchley as the 

 female of his JV. confusus. Prof. Morse tells me the male confusus is a 

 distinct species.
