with a slight violaceous tint, the abdomen more or less fulvous, 

 claws appendiculate, anterior cavities closed. 



Hah. Rlchmond, N. S. Wales. 



A very handsome species, of which I hâve seen four spécimens 

 received from D"" Staudinger, two of thèse hâve an unspotted thorax 

 and no dark markings within the rufous apex of the elytra; the 

 species differs in coloration from any of its congeners or those of 

 allied gênera. 



RICHMONDIA n. g. (CHRYSOMELiNiE). 



Body elongate, palpi subfiliform, antennae long and slender; 

 thorax subquad rate, transverse, elytra wider than the thorax, irregu- 

 larly sculptured, their epipleurae narrow, furnished with short 

 pubescente near the apex, legs slender, the tarsi of nearly equal 

 length, claws simple, widely distant, prosternum narrow, not raised, 

 longitudinally sulcate, its base truncate, mesosternum short and 

 narrow, sulcate, anterior coxal cavities closed. 



In most of the structural characters, this interesting genus 

 agrées with Aesernia but the closed coxal cavities and the différent 

 shape of the prosternum show its greater affinity to be with the 

 Timarchinœ from which the shape of the thorax, antennes etc. 

 again separate it. The peculiar structure of the elytra in this 

 species resembles that of a Chlamys or one of the Cassididœ and 

 will distinguish the insect at first sight. 



Richmondia camelus n. sp. — Fulvous, the antennœ, tihiœ 

 and tarsi dark metallic hlue, head, thorax and elytra greenish- 

 œneouSy strongly punctured ayid foveolate, elytra greenish œneous, 

 the shoulders strongly prominent, the hase with a highly raised 

 conical purplish hunip, rest of the surface verrucose. — Length, 

 10-11 mill. 



Head closely punctured, triangularly depressed between the eyes, 

 the labrum and palpi fulvous, apical joint of the latter piceous, 

 antennse as long as the body in the maie, shorter in the female,

 quadrate, one half broader than long, the angles tuberculiform, the 

 sides rounded at the middle, the surface strongly but remotely 

 punctured at the dise, the sides closely punctate, the middle with 

 an elongate partly interrupted dépression, the anterior margin 

 straight, poslerior slightly produced at the middle, scutellum 

 smooth, triangular, purplish; elytra much wider at the base than 

 the ihorax, the shoulders strongly produced in shape of an acute, 

 oblique ridge, the basai portion near the suture raised into a high
