there at ports of entry. The two specimens in the collection of the 

 National Museum from north of New Orleans and at Brookhaven may 

 have been introduced in shipments of fruit to New Orleans. It is one 

 of the reddish-brown species and easily recognized because of its size 

 and relatively fine punctation.
