PALL— A REVIEW OF NOTIOPHILUS

dorsal puncture a little more basal in position; the sides of the prothorax a 
little straighter and very feebly sinuate posteriorly. The palj)! and antennae 
are colored as in aquaticus ; the tibiae arc black in all specimens seen. 
Length .1.4 — 4.65 mm. 
Four specimens, all V 's, have been sent by Mr. Wickham. They bear labels 
as follows ; Mullan, Alontana ; Leavenworth \'alley and Silver Plume, 9000- 
1 1000 feet, Colorado ; Houston, Texas. There is a specimen, also a 9 , in Dr. 
Pilaisdell's collection from Coeur d'.\lene, Idaho, probably also collected by 
Wickham. 
Simulator is the nearest aj)]>roach in onr fauna to the Siberian sibiricus 
of which there is a specimen in the LeConte collection labeled “Ajan,” and sent 
by Motschulsky himself. This specimen, writes Air. Blanchard, "is a little 
larger than simulator, prothorax a little more narrowed at base and sinuate 
each side behind, the elytra with humeri more arcuate each 'side to meet the 
narrowed prothorax, elytral striae more produced behind and more coarsely 
])unctate excejn at base, the elytra apparently a little more elongate." These 
differences, it will he seen, are precisely those which separate simulator from 
aquaticus, and were it not for the two apical ])unctures in sibiricus it could not 
possibly be separated from aquaticus. 
Ch X. novemstriatus Lee. 
Our smallest species, and withal the commonest in the eastern United 
States. It is easily recognized by its small size, rather strongly bronzed surface 
lustre, very broad second elytral interspace and consequent crowding of the 
lateral striae, and two apical annulate punctures. The inner ones of the lateral 
striae are more or less completely obliterated before the apex, the apical portion 
of the first of these (the second stria) however, remaining as a short isolated 
furrow. Two or three of the striae before the deeply impressed seventh are 
always nearly or quite entire. The four basal joints of the antennae, and the 
tibiae, are always pale, the palpi dark except at base. There is occasionally 
a pale apical elytral vitta, more often seen in sj)ecimens from the Southern 
States. In all the ])receding species the surface of the elytra is polished 
throughout, there being only the faintest indication of alutaceous sculpture at 
the extreme apex. In the present S])ecies the ajiex is always distinctly 
alutaceous for a short distance, and this sculpture exists in all the following 
species, becoming strongly marked in the 7-striate and 12-striate groups.
