the body, dark cliestnut-red and glabrous ; the short, 

 curved, clavate basal joint is transversely ridged like the 

 femora, the 2nd to 6tli are sparingly punctured; the 11th 

 joint is slender and nearly one-fourth the length of the 

 entire antenna.

Callichroma Ni/asscR. 



Gracile, cyaneum vel viridi-geneum, supra nitidum, 

 subtus argenteo-sericeum, femoribus et tibiis 4 anticis (his 

 basi exceptis) femoribusque posticis dimidio basali, rufis ; 

 antennis $ corpore longioribus, articulo basali apice extus 

 spinoso, tei'tio sequenti paulo longiori, 3 — 10 lateraliter 

 sulcatis, apiceque subtus incrassatis ; thorace medio Irevi, 

 lateribus subtiliter sparsim striatis ; elytris elongato-sub- 

 parallelis subtiliter punctulatis et minute strigulosis,^ sed 

 nitidis, glabris ; femoribus posticis abdomi^ie paulo longi- 

 oribus, gradatim clavatis. 



2 Antennae corpore vix breviores. 



Variat : tibiis omnibus femoribusque posticis chalybeo- 

 nigris ; elytris lateribus violaceis. 



Long. 9 — 10 lin. 



A moderately narrow and elongate species, differing 

 from the typical CallichromcB in the slightly clavate hind 

 femora. The other characters are those i" ihe genus, and 

 the hind tibiae are compressed and flexuor.s along their 

 upper edge as in the typical species. Thi ead is nearly 

 smooth, having only a few faint longitudir-"' strige. The 

 thorax is rather longer than is the rule in . .e genus; the 

 lateral spine less acute, and the other lateral prominences 

 wanting. The anterior and posterior transverse constric- 

 tions also are very slight and marked only by a few fine 

 furrows. The scutellum is scutiform and nearly smooth.

Macropsebium, nov. gen. ( Sub-fam. NecydalincB.) 



Gen. Psebio (Pascoe) proxime aflfine. E rnaximis hujus 

 subfamili^. Corpus elongato-oblongum, supra planatum. 

 Caput exsertum ; epistoma brevissimum, a fronte sutura 

 profunda separatum, fere articulatum ; oculi supra ( (? ) 

 separati, minus subtiliter granulosi ; palpi graciles, articulis 

 terminalibus lineari-compressis. Antennae {$) corpore 

 dimidio longioribus, articulis 3 — 11 subtequalibus, in 

 laminas lineares compressis ; 1"'° brevi, crasso, diflbrmi.
