Galochromu* that I have seen ; a thick wheal-like edging com- 

 mences at the posterior angles and proceeds a very short distance 

 along the lateral margin and then curves inward and arches 

 across the middle of the disc, being however narrowly interrupted 

 on the middle line by the longitudinal median impression. There 

 is an obtuse gibbosity on either side of the middle line imme- 

 diately in front of the base and a somewhat deep excavation 

 immediately within the hind angles. The prothorax is entirely 

 margined with a thickened edging which however is not so thick 

 as the wheal-like carina that crosses the disc.

C. Kochi, sp. nov. Sat cylindricus ; sat nitidus ; niger, elytris 

 metallico-versicoloribus (in disco cceruleis, latera versus aureo- 

 viridescentibus, suturam versus purpurascentibus); capite 

 crebre sat sequaliter punctulato, inter oculos quam anten- 

 narum articuli basalis lungitudo fere angustiori ; sulcis 

 ocularibus nullis ; antennis quam corporis dimidium sat 

 brevioribus, articulo 3° quam l us 2 US que conjuncti manifeste 

 longiori, quam 4 US 5 US que conjuncti manifeste breviori, 

 articulis 8° — 10° quam prrecedentes multo brevioribus; pro- 

 thorace quam longiori fere duplo (postice quam antice duplo) 

 latiori, crebre subtiliter distincte sat aequaliter punctulato, 

 lateribus (superne visis) pone medium fere parallelis, basi 

 media sat anguste sublobata, angulis anticis obtusis ; elytris 

 sequaliter sat subtiliter (quam G. I/owitti, Pasc, vix minus 

 subtiliter) postice magis subtiliter seriatim punctulatis, 

 interstitiis planis subtiliter (quam series permulto magis 

 snbtiliter) vix crebre punctulatis ; prosterno sat distincte 

 carinato; metasterno distincte punctulato et fortiter oblique 

 rugato, episternis opacis Jeviter punctulatis ; tarsis subtus 

 nigro setosis, posticorum articulo basali quam 4 US haud multo 

 longiori ; abdomine modice punctulato et longitudinaliter 

 rugato. Long., 9^-1.; lat., 4-f-l. 



This extremely fine species is allied to C. cupreus, Fab., 

 brevipes, Blackb., and grandis, Macl. From cupreus it differs 

 inter alia by its entirely different colouration and (presuming my 

 identification of that species to be correct) by its much more 

 cylindrical form, very much more slender antennae with quite 

 differently proportioned joints and seriate punctures of elytra 

 becoming much finer in the apical third ; from brevipes it differs 

 inter alia by its notably wider prothorax and much finer punc- 

 turation of the elytral interstices (so that the elytral series stand 

 out much more conspicuously); and from grandis inter alia by,
