119. — NOTONOMUS ANGUSTIPENNIS. n. sp. 



Length 5 lines. 

 Differs from the last species in being less brilliant throughout, 

 in having the thorax less rounded laterally, in having the elytra 

 scarcely broader than the thorax, in being destitute of all purple 

 gloss except on the elytra, where it is very slight, and in having 

 the abbreviate stria near the scutellum shorter and more pointed. 

 In other respects the two species are exactly alike.

 1865, III,^a^e97. 



121. — Omaseus Mastersii. n. sp. 

 Length 6^ lines. 

 Black, very nitid. Head smooth in the middle, with two 

 small elongate impressions on each side, the external one 

 linear and extending from the eyes to the base of the mandibles, the 

 other impression rather broader. Thorax almost square, rounded 

 behind the anterior angles, truncate at the base, and very slightly 

 narrowed at the posterior angles, with the median line lightly 

 marked and with two deep basal impressions on each side ; the 

 outer one close to the posterior angle and very short, the other 

 moderately long and very broad. Elytra of a brilliant iridescent 

 hue, with four deep and distinct stride on each side of the suture, 

 and a lateral stria, perfect, with the fifth stria from the suture 

 scarcely traceable towards the apex, and the sixth and seventh only 

 traceable at the apex. The first four interstices are convex. 



122 — ChljEnioideds planipennis. n, sp. 

 Length 8| lines. 

 Black, nitid. Head deeply but shortly bisulcated in front. 

 Thorax rather broader than the length, slightly rounded at the 

 sides anteriorly, scarcely narrowed behind, broader at the 

 posterior angles than at the anterior, and truncate at the base, 

 with the median line very lightly marked, the inner basal im- 

 pressions broad and deep, and the outer almost circular. Elytra
