ANTHOCARIS I. 
ANTHOCARIS OLYMPIA, 1-4. 
Anthocaris Olympia, Edwards, Trans. Am. Ent. Soc., 1871. 
Male. — Expands 1.6 inch. 
Upper side pure white, gray at bases of wings; primaries have at the apex 
a pale gray sub-triangular patch terminating on either margin in a small spot 
of darker color; on the arc a straight black bar, reaching the sub-costal nervure ; 
costal margin slightly specked with black. 
Secondaries have a few black scales at outer angle, and a small wedge-shaped 
black spot preceding these scales on costa ; fringes white. 
Under side white ; primaries have a small gray sub-apical spot on costa, nearly 
covered with green scales, and a faint greenish patch on hind margin partly cov¬ 
ering the discoidal interspaces; discal spot narrow, lunate, inclosing a white 
streak. Secondaries crossed by three bands of yellow-green on a gray ground, 
the intermediate spaces being white ; the first band, near base, forms the seg¬ 
ment of a circle ; the second, just anterior to the middle of the wing, of irreg¬ 
ular width, projects a short, truncated branch on sub-median nervure that con¬ 
nects with the third band, and ends in a sharp spur a little inside abdominal 
margin; the third band, commencing on abdominal margin, is at first broad, 
and after connecting with the second, narrows to half its previous width, then 
enlarges greatly and curves towards hind margin, which it strikes in three 
branches, besides sending a fourth to outer angle ; sometimes this last branch is 
disconnected and forms a marginal spot; these bands all marked more or less by 
small white spots and points. Body black, covered with gray hairs ; beneath 
greenish white ; palpi white with many gray hairs; antennae gray above, yel¬ 
lowish below ; club brown above, bright yellow below and at tip. 
Female. — Expands 1.7 inch. 
Similar to male; the apical patch inclosing a single, distinct, white spot; discal 
mark broader, sinuous, sending a short spur along sub-costal nervure ; costal 
edge more irrorated ; under side as in male. 
The specimens of Olympia originally described, and till then the only ones 
known to me, were taken at Coalburgh, West Va., in April, 1871, by a young 
collector whom I had enjoined to take “ everything that was white,” and were
