OF WASHINGTON. 145 



Described from several specimens collected by Mr. H. G. Hub- 

 bard and myself at the following localities: Marquette, Mich., 

 July 3, 4, and 30; Eagle Harbor, Mich., June 9; Cambridge, 

 Mass., November n ; Fortress Monroe, Va., June 17. I have 

 also seen specimens from the States of New York and Pennsyl 

 vania. 



This species differs from the generic description of Pityoph- 

 thorus as given by Eichhoff (Ratio, etc., p. 173) in the structure 

 of the antennae and the anterior tibias, but since several other 

 North American species described as Pityophthorus even after 

 removal of those which belong to Bedel's genus Pityogenes pre 

 sent notable structural differences, it would be premature to erect 

 a new genus for an isolated species. Superficially the species is 

 at once recognizable from its large size, its less elongate form and 

 the structure of the elytral declivity. 



Since I have never found this Scolytid in situ I am unable to 

 add anything to the knowledge of its life-history. 



Mr. Schwarz pointed out an interesting feature in the history 

 of the Otiorhynchid Aramigus f utter i. A single specimen, 

 found at Cambridge, Mass., by the late Mr. Edw. Burgess, is in 

 Mr. Henshaw's collection, but in 1875 and subsequent years it 

 suddenly made its appearance at many widely distant localities 

 in North America. On the Atlantic slope it occurred usually 

 in greenhouses, rarely outdoors, from Massachusetts to Georgia, 

 being evidently transported from place to place by nursery stock, 

 but since a number of years it has entirely disappeared, except 

 at some isolated localities in the South. In Canada it appeared 

 likewise in greenhouses, and was still present in 1890. In Cali 

 fornia it occurred outdoors, and was still present in 1892. The 

 species does not belong to the fauna of the Atlantic slope, nor 

 to the Pacific fauna, but since it is evidently an American insect 

 its original home is, in all probability, the central region where 

 allied species and genera occur. We would thus have a case 

 analogous to the invasion of Doryphora decemlineata. Some 

 of the original specimens of Aramigus fuller i were received 

 by Mr. A. S. Fuller from Montana, in 1875, unfortunately with 

 out further particulars regarding mode of occurrence, but neither 

 in that State nor in Kansas and Colorado or further South the 

 species has ever been found outdoors since that time.
