6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 89 



Description. — Body of medium size ; length without the terminal 

 pencil of hairs, which is missing, 3.5 mm, width over i mm. Living 

 color almost pure white. Segments 11, number of legs 13. 



Head with the hairs distributed much as in L. comaus, but they 

 are somewhat shorter, and the two anterior areas are not so widely 

 separated. Antennae with joints of dififerent proportions from those 

 of L. comans, as shown in figure i. 



First segment small and with two clusters of hairs as in L. conians. 



Segment 2 with the lateral prominences slightly produced forward, 

 but those on the other segments extend outward ; the hairs on these 

 prominences are straight and radiate in all directions, not curving 

 backward as in L. comans, nor are they as long as in that species,

although some of the longest hairs seem to have been lost from the 

 specimens. Near the side of each segment, close to the posterior 

 margin, is a small cluster of erect, radiating hairs, and along the pos- 

 terior margin there is a close-set series of rather long hairs pointing 

 backward. 



Last segment with all hairs lost, but it is apparent that the terminal 

 pencil was composed of two parts, as there is a round folliculate area 

 above, and a larger reniform folliculate area below it. This caudal 

 pencil of hairs probably was very similar to that of the following un- 

 determined species from Nassau. 



Legs resembling those of L. conians, except that the spine beneath 

 the distal third of the last joint is smaller than the terminal claw.

LOPHOPROCTUS sp. 



Many specimens were collected at Nassau, New Providence Island, 

 January 3, 1932. 



All the specimens are so badly rubbed that it is impossible to gain 

 a complete conception of the vestiture. However, the caudal pencil 

 of hairs is composed of two definite parts, an upper round cluster of 

 very long, light-colored, parallel hairs, beneath which there is a brush 

 of equally dense, dark, parallel hairs about two thirds the length of 

 the upper group but forming a cluster more than twice as wide and 

 considerably thicker. The antennae and other structural characters
