Descriptions of New Mallophaga, II. 



37 



and broken obliquely at sutures, band in last segment half the 

 length of the segment ; central part of segments clear light-brown. 



Male (Fig, 1, F.). Length 3.07 mm., width .81 mm. General 

 form verv close to that of female, markings of head, thorax, and 

 body a little darker, lateral bands not extending into eighth 

 segment. 



Described from seven specimens in Professor Herbert Osborn's 

 collection, taken by George H. Cherrie from Melozone cabanisi 

 and Melozone leucotis, four females from the former and two 

 males and one female from the latter. 



This species shows considerable resemblance to P. subangu- 

 latum Carriker and to P. subhastatum sp. nov. in general formi 

 but differences in size and in arrangement and form of markings 

 and various details of shape seem to require the establishment of 

 a new species. 



This work was carried out in the Zoological Laboratory of 

 Ohio State University under the direction of Professor Herbert 

 Osborn, to whom the writer is greatly indebted for valuable 

 ■assistance.
