NO. 14 MILLIPEDS OF WEST INDIES AND GUIANA LOOMIS 5 1 



Females with a very short ventral crest on the third segment just 

 behind the second pair of legs. 



lOMOIDES HISPIDUS, n. sp. 



Plate 3, figs. 3 and 4 



Two males, one the type, and two females were collected beneath 

 a mango tree on the lower slope of Morne Brigand, near Bayeux, 

 Haiti, July i6, 1927, by H. F. Loomis. The animals were sluggish 

 in their movements, usually remaining motionless for a while after 

 being exposed and were very difficult to see except when turned 

 on their backs, thus exposing the light-colored ventral surfaces. Other 

 specimens were collected at Le Borgne, Haiti, March 26, 1930, by 

 W. H. Jenkins and O. F. Cook. 



Description. — Length of the largest specimen, a female, 9 mm. 

 width 2.2 mm. 



In living specimens the dorsum is dull coal-black and usually some- 

 what incrusted with dirt ; the under side of the posterior subsegments 

 also is dark-colored to the sterna, and the elevated portion of the 

 head between and above the antennae is coal-black; the remainder 

 of the head, the antennae, the legs, sterna, anal valves, preanal scale, 

 papilliform apex of the last segment, and the entire anterior sub- 

 segments are uniformly white or uncolored. 



Head with an inconspicuous median furrow on the vertex. Antennae 

 with joints i, 2, and 3 gradually increasing in length; joint 4 about 

 as long as joint 2, joint 5 twice as thick as joint 3 and somewhat 

 longer, equaling joints 6 and 7 together, of which the latter is the 

 shortest. In figure 25, a, the head and first two segments are shown in 

 ventral view. 



First segment with the median anterior margin nearly straight 

 across, the sides extending obliquely outward and backward ; lateral 

 portions of the back margin directed inward and backward to the 

 straight, transverse median margin. Central area of the segment 

 subglobular, very abruptly raised above the greatly expanded an- 

 terior border, with an anterior row of four large conic tubercles and 

 a posterior row of six smaller ones, each tubercle surmounted by a 

 long seta in addition to the many tiny, erect setae scattered over the 

 entire surface of the segment. A small seta in the middle margin 

 of each of the areas of the expanded anterior margin. 



On the ensuing segments the dorsal surface, including the large 

 tubercles, is hispid with each of the large tubercles supporting a long 

 bristle.
