During the summer of 1930 it was observed that large numbers of eggs of the Oriental fruit moth (Laspeyresia molesta Busck.) were being destroyed by some enemy which pierced the shell and sucked out the contents. The presence of many chrysopid larvae on the trees indicated that these might be responsible for the destruction of the eggs.

Incubation.—Eggs laid in the laboratory January 25 required only 12 days to hatch. This is apparently the length of the normal incubation period. The embryo does not completely fill the egg until shortly before hatching, and its white color forms a contrast against the transparency of the egg shell.

The foliowing is the original description: “Markings of head, thorax and scutellum as usual inthe maculata type, yellow; tegmen with a streak along claval suture auteriorly, an oblique dash at base of corium and another at anterior end of costal plaque, yellow; dot at posterior end of plaque, and in base of fourth apical cell black; and the following markings red, broad vitta based on costal plaque, extending inwardly and crossing clavus as oblique broad band, and a straight narrow stripe, connected narrowly behind to a spot which spreads so as to fill spaces betuween sectors anterior to third and fourth apical cells, also ramose marking on cross veins ; costal plaque dusky bluish hyaline, apical cells fumose. Color below pale yellow. Length: 2.75 mm.

To my knowledge Atlides halesus has not been reported previously as occuring farther north than about thirty-eight degrees N. latitude (southern Illinois), so I believe its presence in north-western Oregon is worth recurding. McMinnville, the location at which I took the examples, is more than seven degrees farther north than points of previous capture. Comstock (Butterflies of Cal., 1927) mentions that this insect is not common in California but that it is recorded from many parts of that state.
