The cage shown in the accmpanying photograph was devised by the writer as an oviposition cage for Oriental peach moths, and for this purpose proved to be very satisfactory. It has also been used with codling moths and strawberry leaf-rollers, and probably could be used with many other insects.

Three new species of Agromyza (Liriomyza, Dizygomyza and Agromyza of European workers) are presented herewith. Some of the material has been in the writers possession for a long time awaiting description. The Holotypes will eventually be deposited in the U. S. National Museum.

In a paper on “The Digger Wasps of the Genus Podalonia (Psammophila)” (Proc. U. S. Nat. Mus., Vol. 71, p. 25, 1927) the writer ended a discussion of the possibility that Podalonia luctuosa Sm. is only a differently colored P. violaceipennis (Lep.) with the statement : “On the whole it seems best to leave luctuosa as a species separate from violaceipennis, for the present, until more pairs have been captured and the evidence they may give becomes available.”

The following bees, obtained by Professor Brittain of Macdonald College, are of more than ordinary interest and should be recorded.

I have not found any records of this group of animals from Alaska or indeed from so far north. In the summer of 1930 I searched many localities throughout this region for these and similar animals of similar habitat. I did not find a single specimen of the insect genus Campodea or Japyx. I did not find the larger Symphyla at any time but a number of these small Pauropoda were found in five widely separated places. Two genera of the group were collected with three species in one and one in the other. Although there were some similarities between these four species and others collected to the southward, all were distinct.

Male : Length 11 mm. Occiput and vertex black; front yellow with a shallow black triangle at vertex, the black extending in a rather narrow stripe to base of antennae, where it is slightly forked; face yellow, cheeks black, this black extending up about to the depressed grooves of the face, which are less yellow and more shining than the rest of the face and somewhat more whitish; lower ends of posterior orbits very narrowly reddish; antennae blackish with first and third joints more or less reddish; style short and thick, third joint somewhat pointed at tip, second joint with a large projection on the side; length of antennal joints about as 15-67-38, of style as 9; proboscis blackish, a little more than twice as long as head.

General ground color yellowish white to semihyaline. Color markings red or orange. Veitex with semblance of white spots surrounded with red, heavier red spot on tip. Pronotum with median, rather small, triangular spot with U-shaped anterior margin and usual angular spots back of each eye. Scutellum with spot on tip, basal angles yellow with red dash on exterior margin of each anterior corner. Clavi with usual red basal anchor-shaped mark, often broken in middle, and quite long dash near tip.

The following synoptic revision of the family Cheliferidae is presented at this time in order to render available for routine systematic use the expanded classification of this important family necessitated by recent morphological and systematic research. It follows along the lines already laid down by the author in previous papers on the higher classification of the Chelonethida as a whole (Chamberlin, 1939, 1930 and 1931) and differs only in the fact that consideration of included species is omitted in all but a few special cases.
