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



margins reflexed, anterior margin subtruncate, posterior margin 

 truncate, well inserted in the pronotum ; ocelli rather nearer to 

 eyes than to each other. Eostrum reaching the intermediate coxae, 

 second joint longest. Antennas five-jointed, basal joint stout, not 

 quite reaching apex of head, second and third joints longest and 

 subequal in length, fourth and fifth joints a little shorter and sub- 

 equal. Pronotum convex, deflected anteriorly, broader than long, 

 the whole lateral area produced into a broad subacute angulation ; 

 scutellum convex, more than half the length of the abdomen, its 

 apex narrowed and rounded. Corium with its lateral margin convex, 

 its apical margin slightly rounded. Membrane with longitudinal 

 veins emitted from basal cellular areas. Abdomen with the lateral 

 margins entire, not projecting beyond corium. Prosternum longi- 

 tudinally sulcate, mesosternum obscurely carinate ; metasternum 

 obscurely elevated. Legs moderately robust ; tibias sulcated, tarsi 

 three-jointed. 



A very distinct genus of the Tessaratominse belonging 

 to the Division Eusthenina, Stal., and not closely allied 

 to any genus with which I am at present acquainted. 



Vitruvius insignis, sp. n. 



Ochraceous ; anterior lateral margins of pronotum, lateral margins 

 of corium near base, some obscure longitudinal series of punctures to 

 pronotum in about six series, a double discal series at base of scutellum, 

 and some scattered punctures on disk of corium and apical area of 

 scutellum, black. Body beneath luteous, legs ochraceous. Head 

 finely wrinkled and punctate, pronotum more coarsely so and with 

 two elongate transverse impunctate spaces near anterior margin ; 

 scutellum distinctly transversely wrinkled, with a faint and broad 

 central impression ; corium somewhat thickly and finely punctate, 

 but longitudinally levigate on disk. 



Long. 17 millim. Exp. pronot. angl. 10| millim. 



Habitat. Burma ; Rangoon (Fea). 



Byrsodepsus nigritus, sp. n. 



Piceous ; rostrum and apical joint of antennae — excluding base — 

 brownish - ochraceous. 



Antennae with the second joint longest, third joint prominently 

 dilated and slightly shorter than fourth joint ; head coarsely and 

 rugosely punctate, the lateral lobes long and well separated in- 

 ternally ; pronotum rugosely punctate, a broad transverse impression 

 on anterior area which becomes foveate at lateral margins which are
