8. Pissodes schwarzi n. sp. 



(Plate III, fig. 8; Plate XVI, fig. B.) 



The type specimen is labeled "Type No. 7455, U.S.N.M.;" 

 name; "Veta Pass, Col, 24.6; Coll. Hubbard &Schwarz; 9 ." This, 

 together with another specimen, a male from the same locality, was 

 evidently collected by Mr. E. A. Schwarz, for whom the species is 

 named. The specimens were found in the United States National 

 Museum under P. costatus. 



Distinctive characters. — This species is evidently confused in col- 

 lections under the name P. costatus. Specimens of P. schwarzi and 

 P. yosemite had been referred to P. costatus by the writer until the 

 specimens from Sitka spruce were recognized as representing the 

 latter. With possibly a single exception, the specimens referred to 

 by Le Conte under P. costatus evidently belonged to P. yosemite. 

 P. schwarzi is not allied to the specimens I have referred to P. costa- 

 tus. In general appearance it comes nearer P. yosemite and P. wehhi, 

 but according to the character of the fork of the male genitalia it 

 falls in the series with P. ayproximatus , from which it is distinguished 

 by the narrow pronotum with coarse punctures and by the larger 

 posterior spots of the elytra. It is distinguished from P. webhi by 

 its relatively broader pronotum, the punctures of which are less 

 coarse and more densely placed, and from P. yosemite by the same 

 character; also it is distinguished from both by its distribution. 



Variations. — There is quite a wide range of variation in size, the 

 length ranging from 5.2 to 6.7 mm., and in the density of the pro- 

 notal punctures, size and density of spots of scales, and relative ele- 

 vation of elytral interspaces 3 and 5, so that some specimens may be 

 found which appear to connect it with the other species, but it is the 

 writer's opinion that when we know more of the habits and seasonal 

 history of the northern Rocky Mountain Pissodes some of the spfecies 

 here included will be found to represent one or more undescribed 

 species, and especially Hopk. U. S. 2386a, which was found ovipos-
