106 Mr. W. L. Distant's Enumeration of the 



margins straight but convexly rounded towards apical angles, 

 posterior margin straight, anterior margin moderately concave. 

 Scutellum small, triangular, about one-third the length of abdomen. 

 Corium small the apical margin concavely sinuate ; membrane 

 large, a little more than half the length of abdomen. Anterior tibiae 

 dilated and spined at apices. 



This genus is allied to Blxna, Walk. ( = Macrhy menus, 

 Sign.), from which it can be at once separated by the 

 shape of the scutellum. 



Heurnius typicus, sp. n. 



Black ; posterior margin of the pronotum, the scutellum and the 

 corium dark castaneous ; antennae ochraceous ; membrane greyish ; 

 legs castaneous, the tarsi ochraceous. 



Body above thickly and very coarsely punctate ; central lobe of 

 head with the apical angles prominent. 



Long. 4 millim. 



Habitat. Burma ; Carin, Asciuii Ghecu (Fea). 



Heurnius erebus, sp. n. 



Black, shining ; antennas pale castaneous ; legs dark castaneous, 

 tarsi ochraceous ; membrane pale greyish. 



Body above very thickly and coarsely punctate ; pronotum with a 

 discal transverse impression. 



Long. 3^ millim. 



Habitat. Burma; Bangoon (Fea); Pegu; Palon, 

 (Fea). 



Broader and less elongate than the preceding species, 

 colour also different. 



Surenus, gen. n. 



Moderately ovate and elongate. Head long and moderately broad, 

 the lateral lobes much longer than the central and broadly cleft 

 between their apices which are obliquely subtruncate, lateral margins

 five-jointed, basal joint robust and reaching the apex of the head, 

 second and fifth joints subequal in length. Rostrum reaching the 

 intermediate coxse. Pronotum about twice as broad as long between 

 the lateral angles which are subprominent, the lateral margins 

 dentate and moderately sinuate, the anterior angles subspinous,
