with narrow black margins and a similar discal mark, the posterior margins strewn with yellow; the yellow 
predominates more beneath. Hindwing transparent, distal margins blackish blue, costal margin yellowish. 
$ very different from the <$. Head, antennae, palpi, thorax and legs deep blackish blue, abdomen the same, 
the 4th segment quite reddish orange, traces of red may also occur on the 5th segment. Forewing deep bluish 
black or violettish black. Hindwing transparent, blackish blue near the base, the not very narrow margins 
and fringe likewise blackish blue. 18—32 mm. Canada, Maine to Florida and Texas, to the west as far as the 
Rocky Mts. This so-called “peachtree-borer” is one of the best known and most hated insects of the United 
States. — The eggs are deposited on the trunk near the soil. The larva lives underneath the bark and produces 
gummous secretions; it pupates in a cocoon spun of wood-remnants and clods of mud. The imago appears 
already in April in the south, the farther to the north the later, until October; it chiefly appears in June and 
July. The wild cherry seems to have been its original food-plant, from which it passed over to the cultivated 
plants; peach-trees are most preferably attacked, besides plums, almonds, apricot-plums, spore-apples (Amel- 
anchier canadensis) and beach-plums. — ab. fitchii Hy. Edw. is the $ form exhibiting, like the type form, fitchii. 
the 4th segment reddish orange and the space between the two interior veins dusted over with black, so that 
the transparent part of the wings is cut in two parts. — ab. edwardsii Bent, is like the preceding form, but the edwardsii. 
5th segment is also reddish orange. — var. luminosa Neum. like the type form, but the margins of the luminosa. 
wings are densely covered with yellow scales, owing to which the insect looks very peculiar. 
C. opalescens Hy. Edw. (= pacifica Riley) (177 h). <$■. head, thorax and abdomen black. Legs black opalescens. 
with white tufts. Forewing transparent with black margins, cross-vein and distal margin broad. Hindwing 
transparent with black margins; beneath the same. head, thorax abdomen and legs blackish bronze. Fore¬ 
wing metallic greenish black. Hindwing transparent opalescent, distal margins and fringe metallic bluish black 
or greenish black; under surface the same. 25—34 mm. Nevada, California, Washington, Oregon. May, June. 
—- The larva lives like exitiosa in the trunk and roots of peach, cherry and apricot and may occasionally also 
do much harm. 
C. graefi Hy. Edw. (177 h). <$: head black. Palpi yellow beneath, black above. Collar in front edged graefi. 
with yellow. Antennae black. Thorax bluish black with a very narrow yellow line on the patagia and the posterior 
part. Abdomen bluish black with narrow pale yellow rings on each segment. Anal tuft white. Legs bluish 
black with yellowish tufts. Forewing transparent opalescent, with a narrow costal and inner margin, the 
latter scaled yellow, but with a broad black distal margin and a similar cross-vein. Under surface dusted yellow. 
Hindwing transparent with a narrow violet margin and cross-vein. 2: head, palpi, antennae, legs and thorax 
quite black, sometimes violettish black, abdomen quite black, forewing deep violettish black or greenish black 
with traces of a darker discal mark. Hindwing transparent with a narrow violet margin and cross-vein, some¬ 
times the cell slightly scaled black. 22—28 mm. Colorado, Nevada, Washington. July, August. — Larva in 
spring in the roots of wild cherry. — var. barnesii Beut. (177 h). Like the type form, but the 4th segment is bamesii. 
orange, by which it resembles the $ of exitiosa (177 g). 28 mm. Colorado. 
C. peruviana Rothsch. (177 h). legs and under surface of body golden yellow. Head, palpi and an- peruviana. 
tennae black. Thorax black with golden yellow margins. The first 4 abdominal segments above black, laterally 
golden yellow, segments 5 and 6 golden, the rest black. Forewing yellowish hyaline, veins, inner margin and 
discocellular band golden yellow, the remaining quarter black. Hindwing yellowish hyaline. Veins, anal margin 
golden yellow, the rest of the margin black. Marcapata. Eastern Peru. 1200 m. 
C. angarodes Meyr. Head bluish black, orbita white. Antennae black. Palpi black, white beneath, angarodes. 
Thorax purple black, a reddish orange stripe on each side, sternum orange on each side. Abdomen bluish black, 
striped white beneath. Anal tuft long, purple. Wings hyaline, veins black, fringe brownish. Forewing with a 
bluish black costal streak, cross-vein black, a broad black distal margin, slightly yellowish ochreous in front. 
Hindwing with a colourless cross-vein and black margins. 20 mm. Manaos, Brazil. November. 1 rf. 
C. xanthomelanina sp. n. (178 e). Antennae yellowish brown, clubs black. Head, thorax, abdomen xanthomela- 
brownish black, anal tuft black in both sexes, in the $ laterally and beneath with traces of yellow. Palpi and 
collar yellow, silvery white before the eyes. The 1st and 5th abdominal segments in the very finely margined 
with yellow, the ring of the 5th extending all around the body; the $ with traces of rings, but distinctly dis¬ 
cernible on the 4th segment. Legs chiefly yellow, the forelegs darker, the ends of the hind tibiae black. Fore¬ 
wing transparent, margins and veins brownish black, in the $ with a moderately broad distal margin which 
is very broad in the $ so that the distal area is only narrow, traversed by 4 veins, anal margin in both sexes 
broadly yellow like the broad discal vein which is finely edged with dark outside and inside, by which it is easily 
distinguishable from many other species. Hindwing transparent, veins and margins blackish brown, fringes 
of all the wings yellowish brown. 21 mm. 1 couple. Itatiaya, Brazil, December. January. Type: Coll. Marten.
