19351 New Ants Collected in Quarantine 35 TWO NEW ANTS COLLECTED IN QUARANTINE
BY W. M. MANN
National Zoological Park, Washington, D. C. The writer has for some years had the privilege of seeing and identifying the ants collected at the various quarantine stations of the United States Government. These are inter- cepted from all parts of the world, and during the course of years a great many species have been received. There is of course a preponderance of certain common tropical species, but occasionally great rarities come in. During the past year two most interesting species have been sent from the station at Honolulu, one a Macromischa, the other a second species of the genus Zatapinoma, both of which seem worth while recording here.
Macromischa luciliae n. sp.
Worker (Fig. 1)
Length 2.75 mm.
Head a little longer than broad, slightly narrower in front than behind, with moderately convex sides, broadly rounded occipital corners and nearly straight borders. Cly- peus, convex, truncate in front; frontal area large and strongly impressed. Eyes convex, situated slightly in front of middle side of head.
Antenna1 scapes barely
surpassing occipital corners; first funicular joint as long as the two following. joints together; joints 2-9 sub-equal in length, slightly broader than long; club elongate; the terminal joint as long as the two preceding joints together. Thorax in profile very arcuate, without distinct sutures ; epinotal spines stout, nearly straight, as long 2s the 'epinotal declivity. Postpetiole long and sl~ender; the peduncle twice as long as the node, which rises abruptly and is higher than long and from above broader than the node and 1% times as broad as long. Femora, especially posterior pair, thick- ened.
Head and thorax closely punctate and siblucid, the thorax and epinotum more closely than the head; petiole, post- Pu&e 42:35-17 (1935). hup Ytpsychu einclub org/42/42-015 html

petiole and gaster shining; legs finely and densely punctate and shining. Hair moderately abundant on head, thorax and abdomen, erect and very coarse, whitish in color. Color pieeous except the anterior half of the epinotal spines which are ivory white; legs and antennae somewhat lighter.
Described from a small series of workers taken in quar- antine at Honolulu on roots of Oncidium splendidurn, from Guatemala.

straight at anterior border; surface at sides with two strong nearly parallel carinse, the surface moderately con- vex. Funicular scapes extending about % the distance to occipital corners, slightly thickened apically ; funiculi mod- erately enlarged toward the tip, the first joint longer than the second and third together; joints 2-10 broader than long; tlerminal joint longer than the two preceding joints together. Thorax robust, pronotum more than twice as broad as long, broader in front than behind and with nearly straight sides; mesonotum from above 1% times as long as PIG. 2. Zatapkoma wheeleri sp. nov. Worker. Profile view and dorsal view of head.
pronotum, narrowed posteriorly ; mesoepinotal suture very distinct; epinotum a little longer than broad in profile, with convex base and declivity ; petiole sub-rectangular. Moderately shining except mandibles and clypeus which are shallowly but densely punctate and opaque, the remain- der smooth. Hairs very sparse, pubescence very fine and short, yellow in color, both abundant on head. Color pale yellowish brown.
Described from three soldiers taken in quarantine at Honolulu on plants from Samoa.
Co-types No. 50801, U. S. National Museum. The only other described species, 2. annandalei, recently described from India by Wheeler, differs in having the head broader, the mandibular teeth smaller and more numerous, and the clypeal area darker than the rest of head.
