Genus Tolumnia. 



Tolumnia cvolu. 



Pentatoma teo/a, Dall. List Hem. i. p. 248. n. 38 (1861) 



Second joint of antcnnaj slightly longer than tiie third, 

 apical margin of corium slightly concave. Other characters 

 generally as in Tohnnnin. 



(renus TiBUACA. 

 Tibraca Urn bat ive n tr is. 



Tibraca Umbativnitris, Stal, Hidr. till KioJiin. i. p. 19 (1858). 

 Monnidea ba.*alis, \\n\k. Cat. Ilet. iii. p. oo.'i (18(38). 

 Mormidea Watkcri, Leth. & S-jv. Cat. GtSn. \Um. t. i. p. 124 (1893). 

 Tibraca basalis, Dist. Ann. & Mag. Nat. Hi.«t. ser. 7, vol. iv. p. 438 (1899). 



Since placing Walker'.s species in the genus Tibraca (supra) 

 I have examined Stal's type of T. limbativentris, and find 

 them both conspecific. 



Genus Eysarcoris. 



Kysarcoris sabarmala. 



HoplUtodera annata. Walk. Cat. Het. ii. p. 266. n. 7 (1867). 



Closely allied to E. guttigera, Thunb. Scutellum a little 

 longer, pronotal angles very slightly more produced. 



Eysarcoris ? insurgens. 



Hoplistodera hisuryens, Walk. Cat. Ikt. ii. p. 2H."). u. 5 (1867). 



This species has the pronotal angles prominently and acutely 

 produced and directed slightly forward. Excluding this 

 character it is allied to E. guttigera, Thunb. 



Eysarcoris? cenescens. 



Ilopli.ffodtra (Pnesceits, Walk. Cat. I let. ii. p. 266. ii. 6 (1867). 



Very closely allied to the j)receding species, but differing 

 by having the ajjices of the {)ronotal angles slightly recurved. 



Eysarcoris alienus, Walk. Cat. Het. ii. p. ilo. n. V> (1867). 



This .«pecic.s is founded on a single specimen without abdo- 

 men. AValkcr describes the sternal process, which " is forked 

 hind ward,'* but proceeds to remark that " it differs somewhat 

 from the typical form of Eysarcoris^ but hardly sufficient to
