to ulkei, but the punctuation of the elytral striae, as well as 
that of the intervals, is without a parallel in our representatives 
of the genus; in short, the species does not display any great 
affinity to any others known to the writer. 
Sphenophorus nevadensis, new species. 
Form similar to vomerinus, more depressed, shining black. 
Rostrum two-thirds as long as thorax, interccular fossa distinct, 
elongate-oval, with fine impressed line reaching to dilated portion above 
scrobes. Thorax as long or nearly as long as wide, sides nearly evenly 
strongly arcuate, a little more strongly anteriorly. Elytra one-fifth wider 
than thorax and fully one-fourth longer than wide. Striae deep with 
much stronger punctures than in -vomerinus group, visible on surface, 
less obvious apically, and stronger to the sides, somewhat distantly 
placed; penultimate and antepenultimate striae indicated by large deep 
punctures, middle of sixth stria usually similar; intervals i, 3, and 5 
slightly concave or flat, closely and finely punctulate, either in one or 
two rows, the others less closely uniseriately punctulate except antepenul- 
timate (9) which is biseriate. Pygidium densely punctate, coarsely 
except at apex where it is much finer, vestiture wanting or very sparse. 
Lower surface punctuated more finely than on thorax. Legs nearly as 
coarsely, but more sparsely punctate than on thorax. Anterior tibiae 
obliquely truncate at apex. Third joint tarsi: anterior , middle and 
posterior , wider than first. 
Length 8.5-9 mm., width 3.2-3.8 mm. A small individual measures 7 mm.

characters which to save repetition have not been mentioned. 
9 . Pygidium narrow, acuminate to apex where it is narrowly 
rounded.

Type. No. 8975, U. S. National Museum. Co types in Car- 
negie Museum at . Pittsburg, Pa. 
In the punctuation of the elytral striae this species is unique, 
resembling somewhat retusus and subulatus in both of which, 
however, the intervals are convex. 
Sphenophorus fallii, new species. 
Of similar form to arizonensis, more shining; elytra rufopiceous. Ros- 
trum shorter, more suddenly compressed at apical fourth; intercular 
puncture elongate, terminating in a strongly impressed line extending 
beyond the scrobes. Thorax more finely punctate. Elytral striae inter- 
rupted by less rounded more or less subcordate punctures more closely 
set, about 18 to each stria. Lower surface with last segment coarsely 
and deeply punctate. Anterior tibiae truncate; subapical spurs feebly 
developed. Anterior and middle femora fimbriate in middle half. An-
