Pine, fir, and spruce are known definitely to be host 

 plants of this species.

 (1908 Proc. Acad. Nat. Sci. Phila., lix, p. 489) 



Recorded from Quebec, Ont., N. H., Mass., R. I., N. Y., 

 Ga., Colo., Texas, Calif, and Br. Columbia. 



Of about the same size and general aspect of Oliarus 

 5-lineatus, but readily distinguished from that species by 

 three mesonotal carinae. It varies greatly in the extent of 

 the elytral maculation. 



The original description is quoted here. 



"Vertex short, transverse, arcuated, its anterior and posterior 

 margins about parallel, its outer angles rounded, median carina not 

 pronounced; transverse compartment at the apex of the head but 

 slightly narrowed at center. Front proportionately longer than in 

 pini, but shorter than in stigmatus; black with the strong carinae 

 fulvous; clypeus abruptly fulvous, its apex and the tylus blackish, 

 basal margin strongly angled. Pronotum linear and deeply angled 

 as in the allied species; soiled fulvous-yellow as are the carinae of 

 the vertex and the tegulae; mesonotum deep black with a pale point 

 at the posterior end of each carina. Elytra abruptly widened near 

 the base, then almost parallel to the stigma; whitish hyaline, nervures 

 white conspicuously dotted with black, costal stronger with about 

 16 larger dots before the stigma, a few of which are grouped where 

 the transverse band touched the margin; the radial forked nearer 

 the base than is the second ulnar. In fully marked specimens the 

 base of the elytra are deep fuscous or black to behind the tip of the 

 scutellum; a broken linear transverse band crosses about halfway to 

 the stigma and another at the stigma; sometimes there is a costal 

 spot between these bands, and the transverse nervures at the base 

 of the apical areoles are heavily brown. Frequently the base is but 

 slightly obscured and the anterior band and costal spots or all the 

 markings are wanting or feebly indicated. Beneath black varied 

 with soiled yellow ; legs pale with the femora more or less fuscous. Ab- 

 domen black with the narrow edges of the segments and base of 

 the genital pieces of the female pale; in the male the plates, inferior 

 surface of the pygofers at base and a dot at each incisure on the 

 edge of the abdomen is pale. Plates of the male short, slender at 

 base, abruptly expanded above in a transverse oblique plate lying 

 against the slightly oblique apical margin of the genital segment;
