margin cut off obliquely before base of corium, deeply sinuated in 

 front of scutellum, the disk with a transverse median impression. 

 Scutellum impressed in the middle. Orificia curved toward anterior 

 angle of metapleura but not nearly reaching this angle. Hemelytra 

 passing apex of abdomen by a little less than half the membrane; 

 membrane with two veins, one somewhat within the outer margin, 

 the other near the inner margin. Abdomen not broader than the 

 closed hemelytra, male genital segment with some long hairs directed 

 backward. Legs rather slender, glabrous. 



Length (without membrane). — Male 2 mm. 



Tpye.— Cat. No. 20153, U.S.N.M. 



China (Hongkong, A. Koebele). 



In shape and color this insect, like the species of Macrotrachelia 

 Eeuter, reminds one of a Thrlps. 



Only two species of this interesting genus were previously known, 

 one from the Balearic Islands, the other from Kilimanjaro. 



Family MIRIDAE. 



IX,* new genus. 



Body oblong, subparallel between base of hemelytra and base of 

 cuneus; punctulate above, except head and pronotal calli; impunc- 

 tate beneath, except the punctulate propleurae. Head narrow, sub- 

 horizontally projecting, about one-half longer than broad and more 

 than twice longer than its basal height; eyes somewhat removed 

 from base of head, large but moderately prominent, seen from above 

 elliptical, considerably longer than broad, seen in profile obliquely 

 subovate, occupying the whole height of the head; anteocular part 

 shorter than eyes, seen from above triangular, acute at tip, seen from 

 the side rounded at apex; clypeus not separated from the forehead 

 by an impression, lorae confluent with genae, the part of the vertex 

 lying between the eyes narrower behind the middle ; postocular part 

 of head separated from the rest of the head by a distinct constric- 

 tion visible round the head both above (where it is a little curved 

 backward), on the sides, and beneath, shorter than the anteocular 

 part, slightly widening from the constriction to the base and form- 

 ing together with the apex of the pronotum a subcylindrical neck 

 which is a little broader than long and slightly narrower anteriorly ; 

 throat long, almost straight and horizontal, interrupted only by the 

 postocular constriction; antennae inserted at the anterior angle of 

 the eyes, slender, but the first joint somewhat incrassated, narrower 

 at base and apex than in the middle, half the length of the head 

 and passing apex of head by two-thirds its length, second joint 

 much longer than first; rostrum reaching a little beyond anterior 



'i£=an insect injurious to vegetation.
