INSECUTOR INSCITI^IJ MENSTRUUS 197 



This subfamily differs from others in the following char- 

 acters: (1) thick body, which is convex beneath; (2) short 

 and broad head; (3) antenna arising from the anterior lobe 

 of head; (4) much elongated scutellum; and (5) distinct 

 corium, which is scarcely longer than the scutellum. In gen- 

 eral, this subfamil}' seems to be more closely allied to the 

 Aradinae than to the Mezirinae. 



Eumenotus pacao, new species. 



Male. — Blackish brown. Head very much broader than long, 

 compressed, bilobed anteriorly, with a small but prominent 

 tubercle in middle ; an acute projection in front of the eye. 

 Antenna much longer than the head, moderately compressed ; 

 first joint not protruding beyond the lobular apex of the head; 

 second joint longest ; the third longer than the first ; the fourth 

 subequal to the third, somewhat fusiform; apex of the second, 

 apical half of the third, and the v^^hole of the fourth, or the 

 last, joint somewhat darker in color. Rostrum somewhat red- 

 dish, very slender, and reaching the intermediate coxae. Eye 

 small, located at the posterior angle of the head, but not touch- 

 ing the anterior margin of the pronotum. Pronotum somewhat 

 trapezoidal in shape, slightly broader than head at the anterior 

 margin ; slightly constricted transversely at middle ; two irregu- 

 larly shaped nodules on each side of the anterior area. 

 Scutellum elongate, tongue-shaped in outline, with a slight 

 transverse constriction before the middle, somewhat elevated 

 along the median longitudinal line. Hemielytra well devel- 

 oped ; corium short, about as long as the scutellum ; membrane 

 reaching the ultimate segment of the abdomen. Legs not modi- 

 fied ; coxae separate ; tibiae thinner than femora ; the first tarsal 

 joint much shorter than the second. Abdomen convex beneath ; 

 spiracles near the basal margin of each segment ; posterior angle 

 of abdominal segments slightly incrassate and projected ; con- 

 nexivum well defined. Length of body : 8 mm. 



Holotype: Male, collected by me at Kappanzan (about 2,000 

 feet in altitude) near' Toyen, Formosa. The specimen was 

 found on the trunk of a fallen tree. Type in my collection.
