Tetramorium semireticulatum, Arnold. $, (hitherto undescribed), 3-2 mm. Piceous; legs, antennae and mandibles pale brown. Sculpture similar to that of the ^, but stronger, the mesonotum and scutellum irregularly reticulate-rugulose and with a few longitudinal rugae superimposed, basal fourth of abdomen reticulate-punctate and dull, the rest smooth and shining.

Head longitudinally striate between the frontal carinae, the striae widely spaced, large, and connected by a few transverse striae. Sides of head strongly reticulate- rugose, the rugae emphasised longitudinally, the transverse rugae extending across the floor of the demiscrobes. Clypeus with about five longitudinal rugae, the middle one strongest but hardly forming a dis- tinct median carina. Mandibles shining, finely and sparsely punctured. Thorax longitudinally and coarsely rugose, in front more reticulate-rugose, elsewhere with a few transverse anastomoses. The rugae end just before the epinotal spines, the space between the spines and the decli- vity is superficially reticulate and shining. Sides of thorax irregularly reticulate- rugose, the spaces between feebly reti- culate-punctate. Nodes of petiole shining almost smooth, with only a few feeble striae. Abdomen smooth and shining The pilosity on the body is composed of long, thin, yellowish white hairs, fai
