Hyastenus japonicus Miers {loc. cit.) is apparently identical witli

 of the antennal spines, and the spines on the luerns are variable char- 

 acters in longipes. 



Kyastenus, sp. 



Two small and iinmatnre specimens from Lower California have been 

 referred to this genns. The species is distinct from longipes, but its 

 characters can not be distinctly determined Avithont larger and more 

 numerous specimens. The snrface is inibescent. As in longipes the 

 carapace is tuberculous and spinulous, but broader anteriorly. The 

 epibrauchial spine is slender. There is a prominent hepatic spine as 

 in the southern form of lo)igipes; the postorbital spine is slender and 

 between it and the hepatic spine there is a shorter subhepatic spine 

 visible from above. Prreorbital .spine present. The front is broader 

 than in longipes, the slender rostral horns not so divergent, fringed with 

 long hairs on the inner margin. Basal antennal joint witli a slender
