iSgi^] Report OF THE Entomological Branch, 1897. 11 



tinned a critical study of the coleoptera of those little known 

 islands, wliere, in spite of the remarkable fact that it rains at 

 least for some part of almost every day in the year, he has madea 

 large collection of extreme interest. Several species, previously 

 only know by one, or very few specimens, have been obtained 

 in large series. Among such may be mentioned the curious 

 Liparoceplialus brevipennis. Mack., L. cordicollis, Lee, and Tany- 

 rhinuii singularis, Mack. Some species new to science have 

 also rewarded his painstaking researches, such as Haida Keeni, 

 Fauvel, and Platycerus Kceni, Casey. 



Regarding the different orders of insects, there are a few 

 records of general interest, as follows : 



Coleoptera. — Since the last report a valuable contribu- 

 tion to entomological literature," Coleopterological Notices, VII, '' 

 has been received from the author, Capt. Thos. L. Casey, 

 Among the new species described in this volume are several 

 which occur more or less abundantly at Ottawa. With one ex- 

 ception they are all minute beetles belonging to theScydmaenid^e 

 and Pselaphidai, and occurring usually in the damp mosses of 

 swamps, or in the nests of ants. The following is a list of the
