sculpture. The head is a little narrower than the thorax, rounded in front and behind ; 

 behind the eyes it is developed less than their length. The form of the keel on the 

 basal ventral segment cannot be made out, it being covered with hair. In our only 

 specimen the pygidium is not covered with hair, is rough in texture, and fiery-red.

Had. Nicaeagua, Chontales (Janson) ; Panama, Bugaba, Volcan de Chiriqui 

 (Champion). 



The head, with the eyes, as wide as the thorax, rounded in front and behind ; the 

 part behind the eyes not one-half their length ; black, the front and vertex densely 

 covered with pale fulvous pubescence ; the mandibles black, dull ferruginous towards 

 the middle. The antennae short, black ; the scape with fuscous hairs ; the flagellum 

 brownish in the middle beneath, the third and fourth joints subequal. The thorax 

 elongate, narrow, more than twice the length of the head, black; from before the 

 middle a broad band of silvery pubescence runs to the apex ; coarsely punctured, 

 covered with short black hair; the sides at the base tuberculate; the mesopleurse 

 densely covered with silvery pubescence ; the metapleurse coarsely punctured ; the apex 

 of the thorax has a long obliquely rounded slope. The abdomen is not quite so long 

 as the thorax and is wider than it. The basal segment is longer than broad and is 

 hardly dilated towards the apex ; the base is depressed ; coarsely punctured and 

 sparsely covered with silvery hair. The second segment is punctured, sparsely covered 

 with short pale hairs ; touching the extreme base are two yellow round marks, and 

 towards the apex are two larger yellow marks, which are broader than long. The 

 fourth and fifth segments are densely covered with silvery pubescence. The pygidium 

 is obscurely striated in the middle ; the sides densely covered with long silvery hair. 

 The basal ventral segment has a broad and slightly curved keel, the part between its 

 base and the basal part of the segment forming an incision ; the second ventral segment 

 has widely separated punctures and is sparsely covered with long white hair, its apex, 

 as well as that of the other segments, being covered with silvery pubescence. The 

 legs, especially the tarsi, covered with silvery hair ; the calcaria and spines black.

Of similar form to S. melissa, but with the four marks on the second abdominal 

 segment reddish-orange (not pale yellow), the basal segment densely covered with 

 silvery pubescence, and the pubescence on the apical segments golden (not silvery) ; 

 the head is longer behind the eyes; on the sides of the mesonotum at the base are two
