ONISCOIDEA. 721 



Spherillo vitiensis. 



Caput subrectangidatum, anticd truncatum. Segmenta tJwracis nuda, 

 Icevia, margine postico concavo. Abdomen extremitate rotundatum, 

 segmento ultimo ad apicem fere truncato, ad basin angustiore, utrinque 

 excavato. Appendices caudales latitudine valde longiores, apice plus 

 duplo angustiore, truncato, margim externo recto, interno rectangulatd 

 emarginato. Antennas latitudinis corporis longitudine, fere nuda3, 

 flagello articulum guintum longitudine osquante. 



Head subrectangular, truncate in front. Segments of thorax naked, 

 smooth, posterior margin concave. Abdomen rounded at extre- 

 mity, last segment almost truncate at apex, narrower at base and 

 sides excavate. Caudal appendages much longer than broad, apex 

 truncate and more than twice as narrow as base, outer margin 

 straight, inner having a rectangular notch near apex. Antennae as 

 long as breadth of thorax, nearly naked, flagellum as long as fifth 

 joint.

 sixth pair ; d, caudal appendage. 



Feejees, island of Vanua Lebu. 



Length, two lines. Head nearly half the breadth of the thorax, 

 with the eyes on the posterior angles. The caudal appendages are 

 oblong, and subrectangular in form, except that a rectangular piece is 

 taken out from the inner angle. The inner branch is not more than 

 half as long as the base of the organ, and is attached very near the 

 inner angle of base, which inner angle is but little widened or pro- 

 longed inward. Fourth joint of antennae little longer than third 

 joint, and shorter than fifth or second; the hairs are extremely 

 minute, so that the organ appears nearly naked ; they are more nume- 

 rous on the joints of the flagellum. Hairs of legs extremely short, 

 mostly shorter than diameter of joints. Claw of sixth pair about 

 half the length of the tarsus.
