section of the late Dutch Expedition into Central Sumatra: one

 Dipt era, Neuroptera, &c. 



HEMIPTEBA-HETEB OPTEBA. 



Fam. PENTATOMID^. 



Canthecona cognata, n. sp. 



Very closely allied to C.javana, Dall., and in general appearance perfectly re- 

 sembling that species, but differing in having the produced lateral angles of the 

 pronotum almost straight, and not curved and directed forwardly, and with their 

 apices obtusely and not long and acutely spinous as in the Javan species. 



Length, 13 mm. Breadth of angles of proiiotum, 8 mm. 

 Hab. : Sumatra (Forbes). 



Neosalica, n. gen. 



Antennae five-jointed, third joint very small, the basal joint dis- 

 tinctly passing apex of head. Pronotum with the anterior angles 

 rounded, the lateral margins carinate and sub-erect, the anterior por- 

 tion rounded, sinuated about centre, the lateral angles produced in 

 straight acute spines, the posterior margin ampliated and produced 

 over base of scutellum. Scutellum longer than broad, the apex 

 rounded, and slightly passing base of membrane, and with a distinct 

 central longitudinal carinate line. Corium with the apical margin 

 very strongly sinuated. Abdomen with the connexivum extending 

 beyond margins of corium, segmental basal angles produced and 

 spinous. Rostrum extending a little beyond anterior coxae. Meta- 

 sternum with a central sub-triangular keel, of which the basal angles 

 are sub-produced, and the apex narrowed and extending to inter- 

 mediate coxse. Mesosternum with a slightly raised, narrow, triangular 

 keel, the ajiex of which is very narrow, and reaches anterior coxae, 

 and the base very prominently raised in a transverse ridge between 

 the intermediate coxae. Femora slightly thickened, the tibiae sulcated. 



Neosalica is allied to Piezosternum, especially to that form of the 

 genus represented by P. excellens, Walker, for the reception of which 

 that author proposed a new genus, ^'Salica.^' It is easily distinguished 

 by the sternal keel not being produced beyond the intermediate coxae. 



Neosalica Forhesi, n. sp. 



Obscure ochraceous; antennse, lateral margins of the head with the inner 

 margins of lateral lobes, lateral margins of pronotum, base and apical margin of 

 scutellum, connexivum, and stigmata black ; apical portion of fourth joint of
