with distinct, separated punctures. Head, thorax, and epinotum densely

Pruinose pubescence rather abundant, line scattered erect hairs sparely 

 distributed on head, body, and appendages.

Viti Levu: Nadarivatu. 



Near P. perkinsi Forel from Hawaii, but larger, more robust and 

 more coarsely sculptured. There is a faint depression at the meso- 

 epinotaJ suture, which does not, however, break the sculpture and is 

 not as distinct as in perkinsi. The occiput is distinctly concave. 

 Because of these characters it is related to biroi Emery, a New Guinea 

 form, from which it differs in having the head more strongly 

 cribrately punctate and the joints of the funiculus only slightly 

 broader than long. Type. — M. C. Z. 8,687. ■
