was last season as plentiful as pallicornis, although seldom taken pre- 

 viously. O. subhirtus Horn, and O. ephippiatus Say are very rare. I 

 have also one specimen (captured a few miles north of Ottawa on 4th 

 June) of a species which is entirely rufous, except the pectus. It is about 

 the size and form oi pallicornis and appears to be undescribed. 



Acalyptus carpini Hbst., Eilesc/ius bipunctatus Lmn., and E. ephip- 

 piatus Say may all be found in profusion on willows, when they are in 

 bloom. The second species varies a good deal in its coloration. 



Piazorhinus scutellaris Say is not very rare, but my specimens have 

 been mostly accidental captures by sweeping or sifting. I have, however, 

 found it upon hickory in July. 



Miarus hispidulus Lee. has not occurred at Ottawa yet, but is abund- 

 ant in some parts of Ontario. At London on 15th Oct., 1885, I found 

 the seed capsules of Lobelia ijiflata very extensively attacked by larvae 

 from which I reared a large number of beetles. 



Fseudomus trimcatus Lee. By an unfortunate clerical error of a cor- 

 respondent I was led to record this species as occurring at Ottawa upon 

 butternut. On the appearance of my List of Ottawa Coleoptera (Trans. 

 Ottawa Field-Nat. Club, No. 5, p. 71) this species was questioned by Mr. 

 Schwarz (it occurring only in the Southeastern States), and on examina- 

 tion the species was found to be Cryptorhynchus parochus Hbst. (Crotch 

 9233 instead of 9223). I regret that such a mistake should have been 

 made, especially as Mr. Beutenmuller has quoted the record (Can. Ent. , 

 Vol. XXn., p. 258). 



Piazurus oculatus Say is rare here, but I find two specimens labelled 

 as taken upon basswood on 21st July. 



Acoptus siituralis Lee. has been found quite abundantly, sometimes in 

 copulation, on hickory stumps about the end of June. 



Mo7ionycJms vulpeculus Fab. This rotund little beetle can always be 

 found upon the flowers of Iris in spring, busy love-making or puncturing 

 the base of the flower and depositing its eggs. In autumn it can be 

 obtained in any desired number from the pods, few of which are some- 

 times free from it. Many of the beetles are, however, destroyed by 

 Pimpla pterelas Say, which I have bred in large numbers from the 

 infested pods. 



Cceliodes nebulosus Lee. occurs abundantly in June upon mixed 

 vegetation near water, but I have not ascertained what plants it especially
