Orange Mts., New Brunswick and Anglesea, X. J., July. 

 Southwestern Pennsylvania, attacking shells of foreign nuts, 

 (Hamilton ) which habit is by Reitter ascribed to a species some- 

 times considered synonymous, viz., arcrar I forming; District of 

 Columbia, found abundantly in dry twigs of various trees in early 

 spring (7/,-e) ; mines in pith and wood of dead twigs and vines; 

 infests honeysuckle; adults bred March 18 (Hopkins.} This, the 

 first species of the genus to be described, was found in the paste- 

 board cover of an old book, and its actual home is believed to be 

 the United States of Columbia. From the small size, identifica- 

 tions are difficult, and many of the records for this species are 

 probably based on the new species described by Hopkins, especi- 

 ally punctifrons. 



Eichhoff ( 1S9G) says "The North American specimens sent by 

 yourself (i. e., Schwarz) I am inclined to consider Stephanoderes 

 cnnJlir Panz (1791), found in some West Indian seeds." Schwarz 

 found small holes leading straight into the wood of cocoa plum. 

 Chrysobalanus icuco. in Florida, apparently made "for feeding 

 purposes by the polyphagous H. cnnlitus;" he also bred it in 

 numbers from dead branches of black locust, Robin ia pscttdacacia 

 L., at Washington, D. C.t 



*The following species are to be separated by the descriptions which follow the key, 

 viz.: firuni, ntinscyi, asiiuincr, liainainclidis and thoracicus. The aggregation formerly 

 called cruditus is separated into many species, of which punctifrons is nearest to West- 

 wood's type. Though omitted in the key, ernditus is here included, since the records above 

 given cannot be attributed to any of the species recognized by Hopkins.
