sheath, which extends from segment III to the tip of abdomen, from 

 which it protrudes shghtly. Its sides are faintly chitinized along the 

 upper portion, but the apex is heavily chitinized and pigmented, with 

 its rounded tip bearing about six strong hairs. The female genital 

 plate covers much of the last tliree segments of the abdomen and has 

 a strong, hooklike projection on each side under segment VII, which 

 bears three heavy, curving spines along the posterior side. 



The type series consists of 11 males and 15 females, collected from 

 four individuals of the type host. The host in not indigenous to 

 Guam, having been introduced, but it has become fairly abundant.

Type. — U. S. N. M. No. 58962, male adult, from Callocalia in- 

 expectata bartschi, collected by Rollin H. Baker on Guam Island 

 (Marianas), July 29, 1945. 



Diagnosis. — Similar to Eureum cimicodes Nitzsch in general shape 

 and characters, but differing in many details, especially in the 

 chaetotaxy. The setae of the entire frontal area are of much finer 

 texture; the fringe of setae along the anterior margin of the temples 

 is nearly twice as long; while the four long hau's on the posterior 

 margin of the temples are much longer, reaching almost to the posterior 

 angle of the metathorax. The gular plate is of a peculiar shape, being 

 deeply emarginate at posterior end, and bears along each side a series 

 of about eight strong hairs of considerable length, very slender
