OF WASHINGTON. 169 
The Wyoming and Utah specimens agree in having the 
abdomen proportionately narrower and the median smooth 
thoracic line and the apical tufts of the pygidium more dis- 
tinct. This species is very generally labeled ' ' vomerinus " to 
which it is related. 
Sphenophorus subopacus, new species. 
Of nearly the same form as vomerinus, still duller black, punctuation 
finer ard deeper and nearly uniform throughout. Rostrum less than 
half as .ong as thorax, narrow. Thorax very nearly uniformly punctate 
except r.ear base, where it is more densely subrugosely punctate; smooth 
space very small, extending posteriorly from a point just in front of 
the middle. Scutellum not deeply sulcate. Elytra at base strongly 
sinuate and finely marginate, disk somewhat unequal; striae very narrow, 
punctures indistinct, first and third striae approximating at base; intervals 
flat, punctuation practically uniform, punctures same size as those 
of stria;; intervals i, 3 and 5 wider than 4 and 6, i with four rows of 
puictures at base, 3 beyond, 3 and 5 with three rows of fine punctures, 
2 and 4 with from one to three rows. The second and third intervals 
from the margin are strongly depressed as in graminis. Anterior tibiae 
less dilated and not so prolonged laterally. In other respects there is 
so nearly an agreement of the type with vomerinus that a more elaborate 
definition is unnesessary, especially so in the absence of better material. 
Length 9.5 mm., width 3.8 mm. 
California (Ulke) two females. 
Type. In the Carnegie Museum at Pittsburg, Pa., co- 
type No. 8967, U. S. National Museum. 
Sphenophorus monterensis, new species. 
Of very similar appearance to graminis, with the same shaped rostrum. 
Black, shining on ventral surface, opaque on dorsal. 
Rostrum half as long as thorax, with distinct rounded interocular 
fossa and feebly indicated, wide, shallow sulcus; otherwise as in 
graminis. 
Thorax two-thirds as wide as long, basal two-thirds subparallel, basal 
margin slightly bisinuate, apical constriction strong, surface somewhat 
densely and nearly uniformly finely punctate; a distinct smooth inpunc- 
tate median line about as long as the width of the thorax and with 
extremities as near the apex as the base. Scutellum feebly concave. 
Elytra about one-fourth wider than thorax; striae fine, somewhat feebly 
punctate, sutural stria moderately curved at base; intervals (except 
third, which is slightly elevated near base) flat, alternate in width, narrow 
ones irregularly uniseriately punctate, wider ones irregularly triseriately. 
Pygidium finely densely punctate, with pale yellowish apical tufts. 
Lower surface finely sparsely punctate, more coarsely and sparsely on 
metasternum and last ventral segment. Legs polished, finely and sparsely
