XEW SPEEIES AND MISt'EEEANEOES NOTES. 
BY GEO. H. HORN, M. D. 
The few new species described below are mostly of curious forms, 
or of groups not previously represented in our fauna. Others have 
interest in their relationship with Mexican forms, while several are 
indicated as inhabitants of our fauna known previously from more 
tropical regions to the south. 
A few synonyms have been given which need no special comment. 
PTEROSTICHUS Bon. 
P. (Hyperphes) iiiaiiis n. sp. 
This name is suggested for a species closely ailed to angushis, Imt 
of rather less parallel form and somewhat larger size, and always of 
darker color. The head is broader, and more distinctly narrowed 
behind the eyes, which are larger and more convex. The thorax is 
more distinctly narrowed behind from being somewhat more arcuate 
in front. The basal impressions are deeper and longer, while the 
basal marginal line is very short (in angustus extending across the 
entire base). The elytra are more depressed, the sides more arcuate. 
The under side does not present any essential differences. Length 
10-12 min.; .-10-.48 inch. 
In the male the hind trochanter is always two-thirds the length 
of the femur, and sometimes slightly longer than that, the apex very 
acute, while in angmtus the same member is rarely more than half 
the length of the femur and obtuse at tip. 
The essential differences from angustus are — larger size and less 
parallel form, prothoracic impressions deeper and longer, basal mar- 
ginal line here almost absent, except at hind angles, and finally the 
form of the male hind trochanters. 
Occurs in Washington, Nevada, and as far south as Placer County, 
California. 
P. (Hyperphes) caligaiis n. sp. 
Very like angustus, but still more slender and elongate. Castane- 
ous, shining, elytra very finely alutaceous ; head relatively larger, 
frontal impressions moderately deep, optic prominences normally 
large, the eyes very small ; thorax longer than wide, narrower at 
base, sides very feebly arcuate, slightly sinuate in front of the hind 
angles, which are sharply rectangular, median impression moderately 
deep, extending to base and nearly to apex, basal impressions sitigle.
