The lengths of the thoracic segments have been used to associate 

 the male specimens with the females. This species is very close to 

 simillima and longula; it can be distinguished from them by the 

 shorter thoracic segments, the slightly greater length of the prothorax 

 compared with the mesothorax, the granulation of the head and 

 thorax, and the shape of the hind margin of the seventh and eighth 

 sterna. The ninth tergum of the female (figs. 73, 140) has a close 

 resemblance to that of bicaudata, but otherwise these two species 

 are very different. This species seems to be very variable. 



Types: Hypotype, male, Portland Ridge, Clarendon, Jamaica, 

 July 22, 1955, T. H. Farr collector, I J. Parahypotypes, seven males, 

 from different localities in Jamaica, one in USNM and another in 

 author's collection. Five females were also identified, all from 

 Jamaica, one in author's collection. These females agree very 

 closely with the description given by Wygodzinsky (1951). 



Ghilianella spinata, new species 



Figures 28, 47, 69, 80, 84, 85 



Male: Overall color yellowish brown or brown. Head, forelegs, 

 second and third abdominal segments, and apex of seventh tergum 

 darker, brownish. Antenna stramineous to yellowish brown; first 

 segment with four or six yellowish annuli; second segment darker, 

 with four or five more or less equidistant broad yellow annuli; third 

 and fourth segments brownish. Forefemur with many irregular small 

 yellowish areas, spines of outer row of armature yellowish white and 

 black tipped. Middle and hind femora each with basal half stramine- 

 ous, apical half brownish with two broad yellow annuli. Middle tibia 

 with three broad yellowish annuli, apical portion of segment paler 

 than basal. Middle and hind tarsi blackish brown. Spiracles yellow. 

 Body and legs with very scarce short appressed golden pilosity. 



The male paratype has very striking longitudinal lines of yellow 

 pilosity along the inner margin of the conexivium on the bulbosity. 

 These lines may have been rubbed off in the holotype. 



Head from side as in figure 80, granulose; eyes small; two well 

 developed spines behind interocular depression. Interantennal spine 

 poorly developed, a mere wart. 



Prothorax granulose, mesothorax and metathorax sparsely granu- 

 late. Lengths of thoracic segments: 3.4, 4.4, 2.1 mm. Apical half of 

 prothorax narrower than basal, dorsally with two long spines where 

 segment begins to narrow, small elevation on anterior dorsal angle 

 (fig. 85). Mesothorax twice as long as metathorax, with two long 

 spines above at about their own length from caudal margin. Meta- 

 thorax dorsally with two long spines closer to caudal margin (fig. 84).
