with various large ants, especially with Formica exsectohkr, subsericea, e tc., but very often with termites also, particu1a.r- ly in rotten trunks where they insert
themselves between the passages of their victims.
I cannot finish this short notice of the habits of the North American ants that
I have observed thus far, without thank- ing most sincerely my good friends and
colleagues Dr. Ad. Meyer of Worcester,
Dr. Murphy of Morganton, and Dr.
Faisons of Faisons, to whose aid, hos-
pitality and inexhaustible kindness I
owe all that I have discovered. Now
I go to visit the able American myrme-
cologist Mr. Pergandc at Washington
and thence return to Europe,

Eoia inducfata Guen. The moth from
which these eggs were obtained was in very poor condition and the larvae died before pupation, but I believe that the determination is correct and that there are no more larval stages. There is no previous description of this larva.
Egr. Long and nearly cylindrical, less in one diameter but not with any flattened sur- face; one end first a little bulging, then taper- ing to a round blunt point, wedge shaped from side view, the other end (micropylar) roundedly truncate. About eighteen longi- tudinal ribs, fluted at the joinings of the faint regular cross-striae which form square cells. Ribs diminishing by a few before the ends ; micropylar end coarsely irregularly reticu- late.
Pearly white, looking beaded from the
fluted ribs. Length .g, width .4 X .3 mm. The next day turned pink, shading to red at the truncate end.
Stage I. Head rounded, free, slightly
bilobed, luteous, faintly mottled with brown; width .3 mm. Body slender, whitish, a rath- er broad, even, brown-gray dorsal band, sep- arated on joints a to 4 into four diffuse lines, but soon merging into a single, broad dorsal band to joint 13; a broad subventral band, the pair separate. Tubercles pale, nearly obsolete; setae short, dusky with small en- larged tips. Feet pale; segments finely, about 20-annulate. Anal flap pale. Seg-
ments scarcely enlarged centrally, uniform, smooth. After feeding turned greenish by transparency.
Stage II. Hcad round, scarcely bilobed,
free; whitish, a white stripe on the face of each lobe, containing an isolated brown dot opposite middle of clypeus ; many brown dots filling the median suture and apex of clypeus, also on the outer side of the white band; labrum pale; ocelli and tips of antennae brown-black ; width .4 mm. Body moderate- ly slender, smooth, normal, segments, numer- ously [about 20) annulate, hut not distinctly; setae short, black, rather coarse. Dorsum broadly dark brown, cut near its edge by a linear, slightly flexuous, pale yellowish sub- dorsal line, most distinctly at the ends and in incisures ; sides pale green ; a broad subven- tral band, colored like the dorsal one and slightly intensified at tubercle vii on each segment. Venter pale green rather narrowly. Cervical shield more reddish than the rest of the dorsum. Feet all pale.
Stage III. Head rounded, not bilobed,

held out flat, free from joint 2; antennae rather large, divergent, straight ; white with broad bands of brown mottlings, one on side of lobe and one next the median suture;
suture itself brown as also the clypeal suture above; antennae black tipped ; width .6 mm. Body moderate, segments about 30-annulate, rather obscurely. Dorsum broadly brown,
pnlverulent, cut by narrow pale subdorsal line and on joints 2 to 5 by a dorsal line also. Shields concolorous, the anal plate pale at the sides. Subventral fold white, slightly yel- lowish. A broad subventral purple-brown
hand, emphasized below the spiracle by a darker patch ; a nearly contiguous pale line below this band ; venter narrowly white. Feet pale outwardly; setae short, black ; tubercles minute.
Stage IV.
Head white with brown dotted
bands as before; width .9mn1. Body moder- ate, uniform, finely annulate. Dorsum dark brown, a fine white subdorsal line continuing the white of head; a paler brown lateral band in part contiguous to a still paler sup- rastigmatal one. Subventral fold white, a trace yellowish. A geminate subventral pale brown band, the upper half containing a
nearly black dot. below and before the spira- cle. Venter not broadly whitish. Feet pale, the abdominal ones faintly brownish marked. No discolorous shields.
Stage V Head erect, rounded, higher
than wide, scarcely bilobed, antennae div tinct; whitish with a brown shade, black dottings on each side from ocelli to vertex and between the lobes over the median sn- ture; sutures of clypeus dark; width 1.1 mm. Body slender, the segments moderate- ly drawn out, the central ones about 25- annulate, uniformly, annulet I somewhat
larger. Whitish, dorsum pulverulently
brown shaded, forming a dark geminate dor- sal line, diffuse outwardly,followed by a pale subdorsal line, on the abdomen faintly, but on thorax and joint 5 distinctly edged by dark dottings. A whitish band on subventral fold; a vinous brown spot below it a little in front of the spiracle, distinct on joints 5 to 7, faint on 8 and 9.
Feet pale or a little brown-
ish dotted, the anal ones elongate triangular. Tubercles minute, dark; setae short, dark, slightly enlarged before tip. Spiracles
brown rimmed. There are some secondary
setae present, forming about twenty hairs in all on each side of a segment, all alike in size and color. Most of the extra ones are subdorsal in a continuation of. the line of i and ii and suhventral posterior.
Food plant unknown.
The larvae fed on
rag weed and clover. Moth from Washington, D. C. Eggs June I, last larval stage July I, but all died soon after without pupating. A NEW USE FOK AN OVIPOSITOR. -Afe-
male Deidamia imcr~~ta emergedin one of
my boxes and in some way injured the first two legs on one side. After two or three days I noticed that when'themoth hung from the lace over the top of the box it clung with the remaining legs, and thriiat its ovipositor up through a mesh of the lace bending its tip forward so that it held like a bent finger. In this position the moth rested for many
hours daily. Caroline G. Sod.
