79. Genus: Conochares Sm. 
Differing from Graeperia by the absence of the appendicular cell on forewings, where the lowest sub¬ 
costal nervule arises from upper angle of cell, the two following nervules are stalked and the two upper ones 
arise free from the cell. The rounded process on frons is somewhat differently shaped and has a raised ridge 
at the end. 
C. acuta Sm. (53 f). Forewings silvery white in basal half, dusted with grey in outer half, edged in- acuta. 
wardly by a blackish central line that is attached at the bottom outwardly to a dusky dusted triangular spot. 
The median line is acutely angulated outwards in the cell to the reniform stigma which is circumscribed by 
white. Hindwings brownish grey. Arizona. 
C. catalina Sm. (53 f). A very pale, yellowish white species with small brownish ringed reniform stigma, cutalina. 
Faint brownish median band and quite extinct brownish marginal band. Hindwings white, brownish at margin 
Arizona. 
€. elegantula Harv. (=- semiopaca Grt.) (53 f). On forewings behind the faintly curved median line, a elegantula. 
•wide brown band intersected by silvery blue, that expands downwards to anal angle. At its outer edge is the 
blackish reniform with a white edge and with a silvery blue spot above it. Marginal area yellowish with brownish 
spots. Hindwings white, brownish at margin. Montana, Colorado, Nevada, California. 
C. arizonae H. Edw. (= seminivealis Hulst, interrupta Sm.) (53 f). Forewings as in the preceding species arizonae. 
with basal half white, frequently somewhat yellowish. In marginal half dusted with grey and brownish, edged 
inwardly by a black slightly curved median line. Brownish reniform stigma with white edge. Hindwings white, 
somewhat brownish at margin. California, New Mexico, Arizona. 
C. hutsoni Sm. (53 f). Forewings yellowish with diffuse brownish transverse lines and median shade, hutsoni. 
a black dot in place of orbicular stigma. Reniform stigma small, round, blackish with white edge. There is 
still a brownish shadow-like streak before margin. Hindwings brownish yellow. Arizona. 
80. Genus: TarachMfa Hamps. 
Exactly like the preceding Genus but with narrow, longish appendicular cell on forewings. The corneous 
plate below the rounded process on frons is triangular and has a raised ridge. Numerous, mostly small species, 
chiefly of north american distribution. 
T. parvula W hr. (= georgica Grt.) (53 f). Fore wings ochreous, dusted with brown in inner and marginal parvula. 
areas, the latter extending in a triangle towards end of cell. A black dot in place of orbicular stigma. Reniform 
stigma a small brown ringlet. From lower angle of cell an oblique extinct line extends to inner margin. Fringes 
metallic leaden, grey-brown. Hindwings fulvous. U.S.A. (Georgia). 
T. bicolorata B. &.McD. (53 f) is entirely devoid of markings. Basal area to end of cell ochreous, paler Ucolorata. 
yellow at costa. Subterminal area suffused with pale crimson, marginal area again ochreous and fringes with 
leaden sheen. Both colours merging gradually in one another. Described from 2 $$ from S. Arizona. 
T. albitermen B.& McD. (53 g). Forewings olive-brown, somewhat more yellowish in sparsely pep- albitermen. 
pered with white that is somewhat denser in marginal area and which contracts towards apex being widest 
on submedian fold. Orbicular stigma is a black dot. Reniform an indistinct darker patch, whence a shadowy 
posterior transverse line extends to inner margin. Hindwings white, faintly brownish. Arizona, California. 
T. tortricina Zell. (53 g). Forewings ochreous, orbicular stigma a black dot, reniform a small blackish 
ringlet, posterior transverse line indistinct brownish from lower end of cell to inner margin with a brown dusted 
triangle posteriorly. Hindwings fulvous. Canada to California. — A variable species: in — f. obsoleta Grt. all 
markings are more or less obsolete, — f. modesta H. Edw. is grey-brown in ground colouration speckled with 
yellowish white, — f. deleta H. Edw. is still darker brown, with the exception of the marginal area and fringes 
which are sparsely peppered with yellowish white. 
T. fumata Sm. is a quite monotonously coloured black-brown species with faint metallic sheen and still fumaia. 
fainter grey dusting. Hindwings dark brown. Nevada, California. 
T. erastrioides Guen. (53 g). Forewings white, peppered with olive-brown and crimson-grey in posterior erastrioides. 
half of median area and in postmedian with the exception of costa. Orbicular stigma a black dot, the small 
brown reniform with black surround. Posterior transverse line black. The white subterminal line is shaded on 
both sides with pale brown. Hindwings white, brownish at margin. Canada to Illinois. — Larva is deep green 
with 12 white longitudinal lines, frequently with intermediate black lines; the head is spotted with black. It 
feeds on Ambrosia artemisiaefolia.
