Fowler, following Reitter, when he puhlishecl his " Coleo^Dtem 

 of the British Islands," sank C. sturmi Bris. as the male, or a 

 variety of C. angustata F. ; in fact, he was inclined to consider that 

 it would be more correct to refer all four to one variable species. 



Muri-aj^ in his Monograph of the genus Catops [Ann. & Mag. 

 N. H. ser. 2, vol. xviii, pp. 12-25 (1856)], was of the same opinion, 

 and the five forms now under consideration were all referred to one 

 variable species ; but he gave us a good account of the three which 

 Kraatz considered to be distinct. From these descriptions Ave can 

 be quite certain as to which insects are really referable to C. cisteloides 

 Frol. and C. intermedia Kraatz, and almost equally certain of C. an- 

 gustata F., as he states that it has the thorax " broadest before middle, 

 gently rounded at sides, gradually narrowed to base." Now in the 

 allied form which I have considered to be C. sturmi Bris., the thoi-ax 

 is broadest nearer the front and is rather strongly narrowed from middle 

 to base. 



On turning to Cox's " Handbook of British Coleoptera," vol. i, 

 p. 401, we find it stated that O. angustata has the posterior coxae 

 short and pointed in the male, whilst C. sturmi has the posterior 

 coxae short and simple. Of course, it is readily understood that Avhat 

 are termed the coxae here are in reality the trochanters. 



Fowler no doubt had both forms under review when he said 

 *' posterior trochanters of male more or less produced into a point." 



It is impossible for me to give any opinion on the synonymy of 

 these insects as quoted by Ganglbauer 1899 and Reitter 1906. They 

 use the name elongata Paj^k. for our angustata F., and ohlonga Latr. 

 for our intermedia Kraatz ; otherwise their work seems to be very 

 much in accord with that of British writers. 



C. angustata F. is the largest insect, with the antennae and tarsi 

 longer than in any of the other four species : the thorax is longer and 

 broader at the base than in C sturmi Bris., whilst the female has the 

 elytra obtusely rounded at apex to the tooth at the sutural angle. 



C. sturmi Bris. is readil}" distinguished by its smaller size, shorter 

 antennae and tarsi, finer sculpture, more rounded thorax, and the el^'tra 

 in female sloping more gradually to tooth at apex. 



The following is a rather more detailed description of C. glauca^ 

 n. sp., in comparison with the closely-allied C. cisteloides, Frol. : — 

 Form narrower, head pitchy black, thorax dark with margins usually 

 paler, margins distinctly flattened and slightly raised, posterior angles 

 more evident ; antennae more or less darkened towards apex ; elytra
