SPH^EEOPHTHALMA. 341 



metapleurae, smooth, shining, irapunctate; the apex blackish. The basal segment of 

 the abdomen is black, covered with rather long pale hair. The second segment is 

 black ; at the base there is a flavo-rufous mark, dilated at the sides ; beyond this are 

 two large transverse oval yellow maculae, edged with dull ferruginous, and nearly 

 uniting in the centre. The third to the fifth segments are covered with silvery hair ; 

 the pygidium is densely clothed with long golden hair. The ventral surface is ferru- 

 ginous, but the apical segments are more or less black ; the basal segment has no keel, 

 the apical part being broad ; the second segment has the punctures moderately large 

 and widely separated ; the other segments are finely punctured at the apex and are 

 fringed with long silvery hair. The legs are ferruginous, the knees and part of the 

 four hinder tibiae blackish ; the tibiae and tarsi are covered with white hair.

Hab. Panama, Bugaba 800 to 1500 feet {Champion). 



Head not much wider than the thorax ; the eyes projecting, the head behind them 

 roundly narrowed, rounded at the edges, not equalling the eyes in length ; rugosely 

 punctured, covered with a short golden pubescence, and with a few longer black hairs ; 

 ferruginous, the occiput and the outer orbits black ; the apex of the mandibles trans- 

 verse, blackish. The scape of the antennae covered with long, soft white hairs ; the 

 third joint about one and a half times longer than the fourth ; the apical joints blackish. 

 The base of the thorax is convex ; the edges end in a short, blunt, triangular tooth ; 

 the basal half gradually becomes slightly dilated and ends in two sharp teeth, the apical 

 tooth being the longer ; from there the thorax is a little narrowed ; the median segment 

 has a gradually rounded slope, its sides being stoutly toothed. The thorax is ferru- 

 ginous, the base, a line down the centre, dilated on either side at the middle, and the 

 greater part of the metapleurae, black ; coarsely punctured, above covered with a silvery 

 and golden pubescence. The apical part of the propleurae impunctate, bearing a 

 microscopic white pubescence, and bluntly tuberculate above. The basal segment of 

 the abdomen ferruginous, and covered with long white hair, the apex having a narrow 

 fringe of golden pubescence, from which a line of golden pubescence runs down the 

 basal third of the second segment ; the sides and apex of the second segment are 

 covered with golden pubescence, and from the apical band a line of golden pubescence 

 runs down to the apex ; the sides of the segments are also covered with golden hair 

 and are ferruginous in colour. The first ventral segment is testaceous ; the basal part 

 is rounded, the apical part with a distinct tooth. The second ventral segment is black, 

 ferruginous down the middle and at the apex ; the punctures not very large, the hair 

 long, sparse, and white ; on its base is a transverse keel. The other ventral segments 

 are ferruginous and covered with long white hair ; they have their apices finely and
