Gen. 14. TigTiOpUS, Xonnan. 1868. 



Genet I < 'li",-a<-l> /-x. General form of body resembling that in Hnriiti<-firit*. 

 though comparatively more attenuated behind. Anterior antennae more robust, in 

 male \er\ -tn>ng. siibchelate. Posterior antennae with the outer ranius composed 

 of 4 di-tinctlx-detiiied articulations. Oral parts on the whole resembling in structure 

 those in //<ii-iirtii-*. First pair of legs, however, with the outer rainus distinctly 

 rticulate. last joint small but well defined, and armed at the tip with a number 

 of sharply curved claws. Inner ramus of 2nd pair of legs in male with the middle 

 joint produced at the end both outside and inside in a deHexed spine; outer 

 ramus of :'jrd pair of exactly the same appearance in the 2 sexes. Last pair of 

 h-i:- of a structure similar to that in /I<n-j>arti<-ns, but with the marginal spines 

 \ery -lender, setiform.
