narrow, bicallose on the disc posteriorly, the margins somewhat 

 rounded, plicate, narrowly notched behind the middle, dilated 

 before and behind this into a moderately prominent dentiform 

 projection, and constricted in front of the acute hind angles ; (9) 

 subquadrate, with the margins angularly dilated and thickened an- 

 teriorly, and sinuate thence to the acute hind angles. Elytra long, 

 wider than the prothorax, parallel or widened posteriorly, flattened 

 on the disc, roughly sculptured and costulate. 



Length (excl. head) 4i-6|, breadth 1|-2| mm. (^ ?.) 



Hab. Panama, Chiriqui. 



Separable from the Mexican and Guatemalan S. lineata 

 (= lineola) by the less orbicular prothorax, with the two 

 dentiform lateral projections more feebly developed, in the 

 male, and by the yellow tip to the antennae in both sexes. 

 The thirteen examples in the " Biologia " collection vary 

 greatly in the colour of the elytra, more than half of 

 them belonging to the var. apicipennis, one having the 

 elytra almost entirely testaceous. Pic, to judge from his 

 description of the prothorax, had females only before him. 

 S. bugabensis has the general facies of certain species of 

 the Hispid genus Chalepus.

Moderately elongate, shining, sparsely pubescent; nigro-piceous, 

 the head and prothorax (a continuous median vitta excepted), the 

 basal third half, or more of the elytra (except along the suture), 

 or the humeri only in some of the Cruatemalan specimens, and the 

 basal half or more of the femora, flavo-testaceous. Eyes very large

 before the base (the general outline thus appearing suborbicular,
