shallow foveolae, finely rugulose on the sides. Pilosity like that of the worker 

 except that the hairs are longer on the venter. Color like that of the worker 

 except that the head, thorax, and petiole, and the spots on the gaster are 

 more yellow even in fully mature specimens. Each ocellus with a small brown 

 spot. Mesonotum and posterior edge of scutellum dark brown. Wings color- 

 less, with colorless veins and very pale yellow stigma. 



Male, — Length 5-5.5 mm. 



Head, including the eyes, broader than long; posterior portion evenly 

 rounded, cheeks short, converging in front. Mandibles well developed, with 

 denticulate blades, overlapping each other. Clypeus somewhat flattened, its 

 anterior border without a median notch. Eyes and ocelli large and prominent. 

 Antennas long, all the joints longer than broad; scape rather short, as long as 

 the first and second funicular joints together; first about half as long as the 

 succeeding joints, which are cylindrical and subequal. Thorax robust, through 

 the wing insertions as broad as the head through the eyes. Epinotum convex, 

 its basal surface passing into the declivity through a broadly rounded angle. 

 Petiole erect, low, very thick and blunt above; in profile with fiat and sloping 

 anterior and convex posterior surface. Seen from behind the upper border is 

 straight or slightly impressed in the middle. Gaster like that of the worker 

 but more slender and without the distinct constriction between the first and 

 second segments. Genitalia small and embedded. Legs slender. 



Mandibles smooth and shining, very sparsely and coarsely punctate. Cly- 

 peus concentrically striated, smooth in the middle. Head subopaque, densely 

 reticulate-punctate. Thorax more shining and finely reticulate and gaster gla- 

 brous and still more delicately reticulate. Sides of scutellum sharply striated. 



Pilosity and pubescence similar to those of the worker. 



Deep black; tarsi and mouth-parts brown; mandibles, outer corners of 

 clypeus, first funicular joint, wing-insertions, trochanters, and inner genital 

 valves, honey yellow. Wings like those of the female. 



The types of this beautiful species are from Vineland, New Jersey. 

 They are in the collection of Professor A. Forel. I have seen workers 

 from, the District of Columbia, Black Mountains, North Carolina, and 

 Manumuskin and Clementon, New Jersey, and all three phases from 

 Lakehurst in the same State. The species has been recorded also 

 from Virginia (Mayr) and Connecticut (Emery). 



Dolichoderus mariae davisi subsp. no v. 



Worker. — Differs from the worker of the typical marice in its somewhat 

 smaller size (2.75-3.5 rnm.) and in the following characters: The basal surface 

 of the epinotum has its greatest convexity behind the middle instead of at or 

 very near the middle as in the typical mariaz. The antero-median surface of 

 the petiole is more impressed and the edge is sharper. The sculpture of the 

 head and thorax is more pronounced, so that these parts appear to be sub- 

 opaque. The red portions of the body are duller and somewhat brownish. 

 The most striking character, however, is the abundant pilosity. The whole
