TETRAMOBIUM. 183 



tolerably distinct ; metanotal spines short, divergent, acute ; posterior 

 lateral angles of metasternum dentate. Pedicel : the nodes some- 

 what massive and high, the 1st node globose with a long petiole 

 anteriorly ; 2nd node much broader than the 1st, transverse in 

 front, semicircular posteriorly and produced a little into cones at 

 the sides ; abdomen broadly oval, truncate anteriorly. 



Length, $ 2'5 mm.

" . Keddish, ferruginous, shining, with brownish-yellow 

 mandibles, antennae and legs ; the pilosity is yellowish, fairly 

 abundant and long. The head is shorter than in T. guineense, 

 and the frontal lamellae and frontal strise are much shorter and 

 more indistinctthan in that species. The clypeus is lightly rounded 

 in front and has on each side an obtuse tooth, .... in the middle 

 carinate, often indistinctly longitudinally rugose. Mandibles longi- 

 tudinally rugose, with black apex and teeth. Antennae 12-jointed. 

 Thorax above lightly arched, posteriorly a little constricted 

 but without an impression, the anterior angles almost rounded. 

 Metanotum with 2 long strong spines. The head is large and 

 remarkably long ; the thorax also massive, densely rugose. The 

 first joint of the pedicel is in front somewhat thick, cylindrical, 

 forming a node posteriorly, as broad as the metanotum, broader 

 than long seen from above, anteriorly semicircular, posteriorly 

 truncate, on the margins mostly bordered with black ; the 2nd 

 node is as broad as the 1 st, much broader than long, and like the 

 1st node coarsely rugose. Abdomen oval, darker posteriorly." 



Length, 2*5 mm.

" . Mandibles striate, indistinctly denticulate. Clypeus feebly 

 carinate, straight and finely crenulate owing to the recurved stria 

 on its anterior margin. Antennal carinae short ; no trace of an 

 antennal furrow. Frontal area very small. Eyes small, placed 

 below the middle of the sides of the head. The scape reaches a 

 little into the posterior third of the head. Head rectangular, 

 lightly concave posteriorly. The club of the antennae thick, the 

 apical joint longer than the preceding two united. Pronotum 

 subangular in front, its anterior margin nearly straight. Thorax 

 without sutures, somewhat convex from front to back, without an 

 emargination, regularly narrowed frcm front to back, feebly sub- 

 margined. Metanotal spines close together, thick, longer than the 

 space between them, their apex curved forward. Two raetasterna
