for Dr. Harvey’s descriptions, and he must be charged with this 
synonym. 
T. pacifica Harv. 
The museum has received, tlirough Dr. Riley, four specimens of 
this species from Alameda County, Cal., January, February and 
March, and with the red number 334. The specimens are all males, 
and confirm the opinion that we have to do with a good species and 
not a variety of the eastern form. The characters pointed out by 
me hold good, save that the orbicular may be as dark as the reui- 
form. As the whole the specimens look more robust and are darker, 
more powdery. 
Ta^iiiocainpa aiiutiliinaciila n. sp.— Ground color pale fawn gray; a 
fine soft tint. Head and thorax immaculate. Primaries with basal and t. a. 
lines wanting. T. p. Hue a curved series of small venular dots. S. t. line rather 
irregular, concolorous or slightly paler, marked by a somewhat darker preceding 
shade (rarely the line will be entirely wanting). A narrow median shade line, 
bent on the reniform, also sometimes wanting. Orbicular concolorous, usually 
obsolete, sometimes outlined by ferruginous scales, moderate, round. Eeniform 
large, upright, concolorous, more or less completely defined by a rusty red-brown 
annulus, always distinct at the outer side at least, and forming the only obvious 
bit of maculation on the entire wing. Secondaries very pale powdery fawn gray, 
with a faint, darker, discal lunule. Beneath pale, powdery fawn gray ; primaries 
with a discal dot and a more or less evident, sometimes obsolete outer line. Sec- 
ondaries with a distinct discal spot. Expands 1.68 inches ; 39 — 42 mm. 
Hab. — Texas, February 17th, 19th and 25th (Belfrage). 
Five good specimens are in the National Museum collection ('coll. 
C. V. R.). The antennae of the male are lengthily bipectinated, the 
habitus and wing form as in my pectinata, to which this species is 
allied. The very pale fawn gray color, the lack of all prominent 
maculation, save the rusty ring to the reniform, and the plump, woolly 
thorax, will readily identify this form. It bears a casual resemblance 
in habitus to Copipanolis, and the assignment of the specimens to 
that series by the collector caused me to overlook them in my studies 
on the Museum material previously. 
The male characters are distinctive. The harpes narrow toward 
tijh which is somewhat drawn out superiorly into an acute point. A 
stout, curved, corneous process frojn the middle of the outer third, a 
smaller process at its base inferiorly and a longer stouter curved pro- 
cess from behind the middle of upper margin.
