208 [September, 



specimens from Sevenoaks, Dorking, Guildford, Weymouth, Wicken 

 Fen, and Mickleham, besides a very remarkable specimen from the 

 New Forest, which makes considerable approach to nqneoloides ; it is 

 rather immature, so that I have not attempted to extract the sedeagus, 

 and I do not myself feel any doubt as to its species. 



The nomenclature of this species is unsatisfactory. Sturm, the 

 first describer, figured it as having green elytra, and in his description 

 says " Die Farbe ist dunkel braunroth, auf der Oberseite fast in das 

 Schwarze iibergehend, die Fliigeldecken siud uberdies mit einem 

 griinen bronzeschimmer iiberlaufen." Dejean could not recognise 

 Sturm's species (probably on account of the discrepancy as to colour I 

 have just quoted) and he described the insect as 0. subcordatvs, 

 adding " rxipicoia, Sturm ? " in the synonymy. Dawson in " Geode- 

 phaga Britannica " appears to have been the first to assign Sturm's 

 name " i-^qncoJa " to this species, and he says " Elytra . . pitchy with 

 occasionally an obscure greenish tinge." I have never seen a specimen 

 with any such coloration, but as the name rupicola is now in general 

 use for this insect it is well to adhere to it. It is curious that Schaum 

 in " Insecten Deutschlands " makes no remark as to this point. 



5. — 0. EUPICOLOIDES, sp. n. Rvfescens, antennis peJibiisque tesfaceis, 

 elytris nic/ricantibiis ; prothorace evidcnter trunsverso, lateribus Jeniter 

 sinuatis,angulis 2)osteriur'ihus subr(clis,hasi immarginata ; elytris sat prof unde 

 striatis, crebre sat fortiter pimctatis. Long. 6^ — 7| vim. 



This insect is, I believe, largely responsible for the confusion as to 

 our forms. I have found it mixed in collections with several of the other 

 species. The sedeagus shows it to be allied to 0. rupicola. It has the 

 coloration of the rufescent varieties of that species, but it may always 

 be distinguished by its shorter form, and by the less coarse punctuation 

 of the elytra, and the thorax always has the sides less convergent 

 behind. It is also confounded with 0. rectanguhis (=^pnncticollis of 

 collections), Imt it has less elongate elytra, a less densely punctured 

 thorax, and the base of this part with less distinct traces of a margin 



I have also seen it placed among 0. brevlcollis, but the broader 

 prothorax of that species, with less punctuation, and sharply marked 

 almost acute hind angles, make the two distinct enough. 



In Mr. Champion's Continental collection there is an Oj^honus 

 from Corfu labelled 0. hrevicoUis, Dej. This specimen is extremely 

 like 0. rupicoloides, but has a shorter thorax, and an sedeagus 

 approximating to that of redangidvs, so that it pertains, I believe, to 

 another undescribed species.
