the middle to the apexj the base broadly rounded, the apex with a semi-oblique slope ; 

 black, covered with black hairs ; a broad curved band of pale golden pubescence on 

 the apex of the mesonotum ; the mesopleurse with golden pubescence ; the apex of the 

 metapleurse coarsely punctured. The abdomen a little longer than the head and 

 thorax united, and broader than the thorax, black ; the basal segment strongly punc- 

 tured and sparsely covered with long fuscous hair ; on the base of the second segment 

 are two small round yellow marks, and towards the apex are two larger ones of the 

 same colour, which are broader than long ; the fourth and fifth segments densely 

 covered with silvery pubescence ; the pygidium finely longitudinally striolate and 

 fringed with long fuscous hair. The basal ventral segment has a long stout keel, 

 which is punctured, and more or less rufous ; at the base it is nearly straight ; the 

 apex is oblique. The second ventral segment is strongly punctured and sparsely 

 covered with long white hair. The other ventral segments are thickly haired. The 

 legs are black and covered with long white hair ; the calcaria and spines are black.

Long. 12 millim. $ . 



Hab. Mexico, North Yucatan (Gaumer). 



Very similar in coloration to S. proclea ; but differing from it in having the third 

 joint of the antennas double the length of the fourth, and in the four spots on the 

 second abdominal segment being reddish-orange (not yellow), the spots large, the 

 hinder pair more rounded in shape. The head subquadrate, nearly transverse in front, 

 rounded behind, densely covered with pale fulvous pubescence ; the part behind the 

 eyes longer than their length ; the basal part of the mandibles rufous. The antennas 

 stout; the scape curved, covered with long white hair; the flagellum brownish 

 beneath ; the third joint twice the length of the fourth. The thorax black, covered 

 with black hair, gradually narrowed from the middle to the apex ; a broad curved 

 band of white pubescence on the apex of the mesonotum ; the base rounded, the apex 

 with a semiperpendicular slope; the mesopleurse strongly punctured and covered with 

 white hair; the apex of the metapleurse much more strongly punctured than the 

 mesopleuree. The abdomen black, covered with black hair; the fourth and fifth 

 segments densely covered with silvery pubescence ; on the second segment are four 

 large roundish orange spots, the hinder pair being the larger. The pygidium 

 coriaceous, fringed with pale hair. The basal ventral segment with a stout keel, 

 hollowed in the centre, the apex oblique ; black, the rest of the segment rufous. The 

 second ventral segment strongly punctured, and covered with long pale hair; the other 

 ventral segments more thickly covered with longer white hair. The legs black, thickly 

 covered with white hair ; the calcaria and spines black.
