immaculate but they may have from one to three well defined yellow 
spots on each elytron, situated as in the spotted forms of M. fulvogut- 
tata Harr. and M. drummondi Kirby. 
This species in the table of Dr. Horn? would come immedi- 
ately after Af. fulvoguttata Harr. It differs from this by 
being generally narrower and more convex, more brilliant, 
with more acute hind angles to the thorax, a more densely 
punctured pronotum, and by having a subserrate ridge on the 
last ventral segment near the side margin. From M. intrusa 
Horn which it superficially resembles, it differs by being gen- 
erally larger, by having the sides of the thorax less parallel, 
and by lacking the uniformly dispersed pile on the elytra; 
and from the recently described VM. piniedulis Burke, a closely 
related species, it differs by being larger and more convex, by 
never having the elytral maculations more than mere spots, 
by having the thorax longer and with sides less parallel and 
by not having the submarginal ridge of the last ventral either 
so distinctly serrate or continued around the apex of the seg- 
ment. 
My series of fourteen specimens represents material taken 
at Carrville, Trinity County, El Dorado County, Tuolumne 
County, Shasta County, and Mount Wilson, Los Angeles 
County, and from the yellow pine, Pinus ponderosa Dougl., 
Jeffrey pine, P. jeffreyi Vasey, digger pine, P. sabiniana 
Dougl., and the big-cone spruce, Pseudotsuga macrocarpa 
Mayr., the Mount Wilson specimens being captured on this 
last. Besides my series, | have examined at least thirty more 
specimens, chiefly in the collections of Mr. H. E. Burke and 
Mr. Ralph Hopping. The species is apparently confined to 
California and in Northern California and the Sierras seems 
to be found only about the pines, while its more common rela- 
tive, M. drummondi Kirby, has a’preference for the Douglas 
fir, Pseudotsuga taxifolia Britt.
