earlier date than aundenta Fabr., which is European. The 

 latter is aurieolor Herbst; and there is another aurulenta of 

 Rossi = austriaca Fabr. See also Olivier and Herbst for 

 our aurulenta. In all those cases where I have rejected a 

 Fabrician name, I have adopted the one substituted from an 

 earlier authority which has been examined for the purpose. 

 In my printed catalogue you will find several cases of this kind. 



HARRIS TO LECONTE. 



Cambridge, May 14, 1853. 



Your specimens of Eurypalpus, with the pupa, were safely 

 received, and I am obliged to you for them. In the dry state 

 I am unable satisfactorily to examine the pupa, which however 

 has in its general configuration considerable resemblance to 

 Eurypalpus. Among my Cebrionidce I find a single specimen 

 of Eurypalpus? from New Hampshire, which I have been 

 hitherto unable to refer to any described genus ; but it differs 

 from yours in having pectinated antennse. It is the Physo- 

 daetylus ? cisteloides of my printed catalogue. I was not aware 

 before receiving your letter how much revolution had been 

 made in the Cebrionidce or Oebroyiites of Latreille. Westwood 

 I knew had divided them into two groups, Cebrionidce and 

 Cyplionidce, but I supposed these would be regarded rather as 

 sections of one family. There is no intimation in your paper 

 in the Lake Superior book that you regarded Eiirypcdpus as 

 belonging elsewhere than in the same group with Cyplion 

 where Dejean seems to have put it ; and now are you not 

 rather hasty in transferring it to the Macrodactyla of Latr. ?, 

 or the Parnidce of Erichson ? 



A few days ago, Mr. Clark found an aquatic larva, almost 

 exactly like one figured by Westwood among the Lampyridce^ 

 but having beneath the terminal segment five bunches of
