XORroES HARRINGTONI. new name. 



Xylonomus canadensis Harrington, Can. Ent., vol. 23, 1891, p. 134. [Not Xorides 

 canadensis Provancher=aZ6opzcius.] 



Type, allotype, paratypes in Harrington collection; Paratype male, 

 metatype (also homotype) in United States National Museum. 

 Parat3'-pe Cat. No. 20933, U.S.N.M. Notes on types. 



In the general black color this species is like cincticornis and stig- 

 Tnaptcrus, but besides the characters used in the table hai-^ringtoni may 

 be distinguished from cincticornis by the pale annulus at the base of 

 the tibia, and from stigmapterus by the habitus being more robust. 



Ottawa, Canada. 



XORIDES CATOMUS (Davis). 



Xylonomus catomits Davis, Trans. Ainer. Ent. Soc, vol. 24, 1897, p. 372. 



Type.~Cat. No. 176, Acad. Nat. Sci. Philadelphia. Notes from 

 types and specimens listed below. 



This species varies from piceous with ferruginous marks on the 

 head to entirely ferruginous. In the ferruginous specimens the legs 

 are ferruginous while in the piceous specimens the hind femora and 

 tibiae are piceous. Wings subhyaline. 



Craigs Mountain, Moscow, Idaho (Davis); Missoula (Brunner), 

 Darby (Bishopp), Montana; Albee, Oregon (Edmonston); Fallen 

 Leaf, California (Herbert); Boulder, Colorado (IVIarshall) , 



Hosts. — Edmonston has obtained this as a parasite of Chalcophora 

 angulicollis in Pinus ponderosa and Brunner as a parasite of Alaus 

 oculatus and from material containmg MemytJirus perlucida. 



XORIDES CALIFORNICUS (Cresson). 



Xylonomus californicus Cresson, Proc. Acad. Nat. Sci. Phila., 1878, p. 380. 



Type.— C^t. No, 1523, Acad. Nat. Sci. Philadelphia. Notes from 

 type and specimens listed below. 



This species is in structure very close to cincticornis, but the ferrugi- 

 nous color will separate it from that species. The color varies from 

 ferruginous to almost piceous, but in the piceous specimens the head 

 is mostly ferruginous and it is also easy to distinguish the piceous 

 color from the deep black of cincticornis. The male differs from 

 cincticornis in the same manner as does the female. 



California (Cresson); Mendocino County (Coquilett), Summerdale 

 (Burke), Fallen Leaf, and Placerville (Herbert), California. 



Host. — Herbert has collected this at Placerville, California, as a 

 parasite of Buprestis laeviventris in Pinus ponderosa.
