ARTHEOPOD FAUNA OF THE WEST INDIES. 461 



related to C. Guildingii. But it undoubtedly differs in having all 

 the tergites except the last immargmate. . It may be recognized 

 from C lineatus by the spine-armature o£ the femur. 



11. Otostigma spicuLrPEEUM, sp. n. 

 Colour a deep green throughout. 

 Sody slender. 



Sead finely punctulate. Coxal plates of the maxillipedes 

 contiguous, armed with four distinct sharp teeth, the process on 

 the femur well developed and subdentate. Antennae long, com- 

 posed of 17 long cylindrical segments, of which the basal two are 

 naked and the rest pubescent. 



Tergites from about the 6th bisulcate and from the 9th mar- 

 ginate ; the middle of the dorsum marked between the sulci with 

 two longitudinal impressions, the lateral portions at the posterior 

 end of the body wrinkled ; the tergites in the posterior half of 

 the body distinctly spicular. 



The sternites not conspicuously bisulcate, anteriorly rugose, 

 posteriorly marked with four abbreviated longitudinal impres- 

 sions, two median, in a line, and one on each side. 



Anal somite small ; tergite spicular above, with a shallow pos- 

 terior impression ; pleurcd moderately inflated, porous almost 

 throughojut, the inferior posterior angle a little produced but 

 rounded and not spined ; sternite narrow, narrower posteriorly ; 

 legs very long and slender, without spines, the segments sub- 

 cylindrical ; the tarsus unspined ; claw spurred. 



Legs with proximal tarsal segment spurred. 



Length about 40 mm., of anal leg 13 mm., of antenna 10 mm. 



Locality. St. Vincent (JI. S. Smith). 



" Pretty common in decaying leaves and under bark ; some- 

 times obtained by beating vines and branches." 



12. *Otostigma occidentale, Meinert, Proc. Am. Phil. See. 

 1886, pp. 185-186. 



Locality. Grande Anse, Hayti {Meinert). 



In its main characters this species is closely allied to the 

 preceding. The differences, however, between the two may be 

 easily tabulated as follows : — 



.«. Antennae composed of 21 shortish segments; the body 



posteriorly hirsute , occidentale. 



h. Antennae composed of 17 long segments; the body pos- 

 teriorly spicular spiculiferum.
