murphy: report on the south GEORGIA EXPEDITION. 89 
points from the lateral angles ( in taurus these are distinct and the pos- 
terior margin of the metathorax is only flatly angulated on the al)domen, 
being indeed nearly straight). 
Abdomen slenderer than in taunis, and with the lateral transverse 
blotches more widely separated on the middle of the dorsum of seg- 
ments three to six than in taurus, where they nearly meet on all the seg- 
ments; ventral genital blotch not so wide as in taurus, this arriving not 
merely from the greater slenderness of the abdomen, but also from the 
fact that the blotch does not reach laterally so near the edge of the seg- 
ments involved as in taurus. 
Male, length 3.12 mm.; width 1.3 mm.; head, length .94 mm., width 
.94 mm. ; the antennas with 2nd segment much longer than in female, 
being longer than 3rd. 4th and 5th together, but the antennal diiTerences 
are markedly less than in taurus.

wood descrihed (in 1874) the ty])e, and only other species 
(proccllaricr Wcstwood ) referred to this genus. The 
measurements recorded l)y him are so much smaller than 
those shown bv the single female s])ecinien of the genus that 
Piaget later had from a rroccUaria i^^hwiali.^. and \\'estwood's 
description was otherwise so brief, that Piaget was constrained 
to establish a new sjiecies for his specimen. Xow, however, 
that I have taken gigas (my specimens are fully as large as 
Piaget's type) from the original host of proccUariic. I think 
it verv likeb' that the two species are Init one. If so, ^^'est- 
wood's name has ]iriority.
