Addia, gen. nov. 



The structure of tlie body in this genus resembles that of 

 Ilerni'cera, especially as regards the structure of the under- 

 side ; the head is deeply inserted in the thorax, thus shorten- 

 ing the prostenium before the cox^, and the hind coxib are 

 rather wide apart. The genus also resembles Ceropn'a, but 

 in that genus the posterior coxse are closer together and the 

 head is less deeply set in the thorax. The fourth joint of the 

 anterior tarsi in Addia (as seen in an Andaman Island species, 

 for the males of otiiers are not known) is as wide in the male 

 as the third. Tlie antennae are somewhat slender, the third 

 joint scarcely so long again as the tirst and second united, 

 4-6 shorter and equal, 7-10 slightly larger, equal, widest 

 anteriorly, terminal joint circular and not pressed into the 

 tenth. In the Pascoe collection there is a species of tiiis 

 genus from the Oriental Region bearing the MS. name I have 

 adopted.
