I have seen ten workers from the G-eolog. Inst. Koenigsberg ColL 
namely No. 218/4297 (Mayr’s type), B 19990, XXB 1476, XXB 9, 
XB 1539, B 19706, B 253 and 
three without nnmbers. In the 
same collection I find a single 
deälated female (B 18978) which 
evidently belongs to this spe- 
cies. It measures only about 
4,5 mm and closely resembles 
the worker escept for the usnal 
modifications of the thorax and 
the presence of ocelli. 
Nothomyrmica petiolata (Mayr) 
Macromischa petiolata Mayr, Beitr. Naturk. Preuss. I, 1868, p. 85, Taf. IV, Fig. 83, 84, £ ;

Worker (Fig. 26). Length about 2,3 — 2,5 mm. 
Head subrectangular, but little longer than broad, with rounded 
sides and straight posterior border. Eyes moderately large and con- 
vex, just in front of the middle of the head. Frontal carinse prominent. 
Mandibles with several small, subequal denticles. Clypeus very con- 
vex in the middle, depressed on the sides, with rounded anterior border. 
Antennse 12-jointed, slender, scapes not reaching to the posterior 
corners of the head, funiculus with a very distinct 3-jointed club, 
which is as long as the remaining joints taken together; first funicular 
joint as long as the three succeeding joints together; joints 2 — 7 narrow, 
subequal, about as long as broad; 8th joint somewhat longer than the 
preceding joints, as long as broad; terminal joint somewhat longer 
than the two basal joints of the club. Meso- and epinotum not so- 
parated by a suture, together forming a single rounded convexity in 
profile. Mesoepinotal suture distinct. Epinotum depressed, armed 
with two sharp spines, which are as long as their distance apart at 
the base, directed backward, upward and outward and distinctly curved 
downward towards their tips, which are slender and acute. Petiole 
distinctly pedunculate in front, with a small, sharp tooth at its 
antero-ventral end; seen from above the segment is nearly twice as 
long as broad, broadest behind, with a pronounced, rounded node, 
somewhat compressed anteroposteriorly, so that its anterior declivity 
is deeply concave, its posterior surface steep and convex. Postpetiole 
about half again as broad as the petiole, nearly twice as broad as 
Fig. 25. Nothomyrmica rugosostriata Mayr.
