 quadrum (Fabricius). Que., Ont., N. H., s. to N. C. and Ala., w. to B. C, Wash., Oreg., Calif.; 

 Europe. Host: Magdalis aenescens Lee, Phloeosinus canadensis Swaine, P. punctatus 

 Lee, Scolytus multistriatus (Marsham), S. rugulosus (Ratz.). For almost 100 years this 

 sp. has been called colon Linnaeus, following Thomson, 1878 (Hym. Scand., v. 4, p. 33); 

 however, Graham, 1969 (Brit. Mus. (Nat. Hist.) Ent., Bui. Sup. 16: 417) saw Linnaeus's 

 and Fabricius's types and established that quadrum Fabricius is the correct name for 

 this species. Sphex colon Linnaeus belongs in Dinotiscus Ghesquiere.
