Clypeus roundly convex, clearly separated laterally, its apex broadly 

 rounded, the sides being also rounded. Thorax strongly and closely 

 punctured. Upper part of mesopleurae roundly dilated and clearly se- 

 parated from the lower; there is no spine on the lower part. Pygidium 

 broad compared with the length, sparsely and strongly punctured, the

1521 Polybia spilonota sp. nov. 



Black, the sides of the clypeus broadly, its apex more narrowly, 

 a mark, dilated in the middle, below the middle of the inner orbits, a 

 small mark on the base of the mandibles above, a narrow line around 

 the apex of the protonotum, a mark on the upper half of the mesonotum 

 at the base, longish, irregular, narrowed below and curved backwards 

 at the apex, following the curve of the suture, a mark, wider than long, 

 on the apical half of the mesonotum, its sides at the base prolonged 

 into narrow lines, as long as the mark itself, the scutellums, the greater 

 part of the metanotum, the mark roundly narrowed, laterally at the base, 

 the sides broadly rounded, a broad line on the apex of the first abdomi- 

 nal segments and narrower lines on the apices of the other segments, 

 yellow; the marks on the mesonotum and scutellum with a distinct 

 orange tinge; tarsi brownish beneath; wings hyaline, the costal ce- 

 llule slightly, the radial distinctly, fuscous violaceous, the stigma dark 

 testaceous. Worker. Length 10 mm. San Marcos, Nicaragua. 



Apex of clypeus broadly rounded, the centre slightly projecting into 

 a short, blunt tooth, transverse in the centre, the sides obliquely nar- 

 rowed. Mandibular teeth rufous. Eyes almost touching the base of the 

 mandibles. A narrow furrow on the front below the ocelli; another above 

 the antennae. A short, distinct furrow on the sides of the mesonotum 

 opposite the tegulae, an indistinct one on the centre at the base and a 

 much more distinct one down the centre of the scutellum. Abdominal 

 petiole longish, fully as long as the second segment, its apex distinctly 

 dilated. Second cubital cellule much narrowed above, as wide there as 

 the space bounded by the two recurrent nervures.

 thickly covered with long white hair. Mandibles rugose at the base. Ba- 

 sal slope of prothorax smooth, sharply keeled above, behind the keel is 

 a furrow which bears some stout keels; the apex is smooth, the middle 

 closely punctured. Mesonotum shining, closely punctured, the scutellum
