XORroES CINCTICOKNIS (Cresson). 



XyloTwmus dncticomis Cresson, Proc. Ent. Soc. Phila., vol. 4, 1865, p. 288. 

 Xylonomus (Moerophora) modestus Eohwer, Proc. U. S. Nat. Mus., vol. 45, 1913, 

 p. 358. 



Type of dncticomis. — Cat. No. 1519, Acad. Nat. Sci. Phila.; type of 

 modestus — Cat. No. 15371, U.S.N.M. Notes on types and specimens 

 listed below. 



Very like calif omicus, but it is to be distinguished by color char- 

 acters. From the other black species of this group the unicolorous 

 tibiae will make it easy to recognize this species. 



Colorado (Cresson); El Paso County, Colorado (Champlain); 

 Corvallis, Oregon; Skokomish River, Washington. 



Host. — Champlain has obtained this as a parasite of a species 

 (.probably chrysocoma) of Leptura in Pinus scopulorum. 



XORLDES FLORID ANUS (Ashmead). 



Xylonomus floridamis Ashmead, Proc. U. S. Nat. Mus., vol. 12, 1889, p. 451. 



Type.— C&t. No. 2121, U.S.N.M. 



This species is known only from the type.

XORIDES STIGMAPTERUS (Say).

Ent., vol. 23, 1891, p. 134. 



Say's type is lost and the specimen in the Academy of Natural 

 Science in Philadelphia bearing the name label and determined by 

 Cresson should be considered as a neotype for this species. Notes 

 from neotj'pe and the specimens listed below. 



The above table wUl separate this species from its allies, while the 

 accounts listed in the bibliography will make its identity certain. 



United States and Canada (Cresson). Specimens from the follow- 

 ing localities are in the collection: New York; Linglestown, Penn- 

 sylvania (W. S. Fisher); Sherbrook, Canada; Rock Creek Park, Dis- 

 trict of Columbia; Rosslyn (Shannon), Falls Church (Middleton), 

 Virginia. 



Host. — W. S. Fisher has reared this as a parasite of Leptura proxima 



in hickory. 



Genus DEUTEROXORIDES Viereck. 



Deuteroxorides Viereck, Bull. 83, U. S. Nat. Mus., 1914, p. 43. Genotype. — 



Xorides albitarsus Gravenhorst. 

 Xorides Gravenhorst and Authors (not Latreille). 



When Gravenhorst in 1829 divided the genus Xorides LatreUle he 

 made no mention of the species on vv^hich Ljitreiile founded his genus,
