Color yellow. Tergites densely clothed with moderately long stiff 

 hairs which are of uniform length throughout. The first tergite is 

 shorter than the two following ones together; anteriorly it is lightly 

 concave; it is twice as wide as the head at base. Rostrum slender, 

 distally decurved, shorter than the head. Antennae exceeding the 

 rostrum by half the length of the sixth article, in addition to the 

 seventh, or more. Antennae strongly clavate, thick; the fifth article, 

 like the more proximal ones, wider than long. 



Number of segments 79 to 86. 



Length up to 25 mm. ; width, 1 mm.

As compared with S. proxima, this is a more slender species which 

 differs obviously also in the much shorter and finer hairs of the dorsum 

 excepting those of the anal tergite which are abruptly much longer 

 than the others instead of being uniform with them as they are in 

 S. proxima. The first dorsal plate is longer, equalling or exceeding 

 the combined length of the next two. The rostrum exceeds the head 

 in length. The antennae are correspondingly longer, the sixth joint 

 being proportionately longer, more evenly cylindrical and not nar- 

 rowed distad as in the otner species. The antennae exceed the rostrum 

 by half the length of the sixth article as in S. proxima. The body is 

 yellow below and along the sides; but along the dorsum it is darker 

 and of an obscure reddish tinge. 



Number of segments, ninety-six. 



Length not accurately determined because of the strongly coiled 

 condition of the type, but apparently between 20 and 30 mm.

 This is at once separable from the two preceding Haitian species 

 in having the rostrum much longer and in the longer antennae. The
