64 COLEOPTERA. 



gafum or Haliday's coarctatimi will stand for the species 

 which they both represent j both descriptions having been 

 published in 1855. 



70. Ptilium Halidaii, Matthews, 1. c, p. 12 (described). 



Mr. Matthews describes this species from a single speci- 

 men, found by Mrs. Matthews under the bark of a dead oak 

 tree in Sherwood Forest, in 1867. It appears to be allied 

 to P. angulicolle, but to be easily distinguishable from that 

 insect by the two deep converging lateral lines on the thorax, 

 which is nearly destitute of any central channel. 



71. EuPLECTUS PUNCTATUS, Mulsaut, Opusc, 12 Cah., 



1861, 76 J G. R. Crotch, 1. c, p. 65. 



Mr. Crotch records two specimens of this insect; one 

 taken at Hampstead, by Mr. E. W. Janson, the other by 

 himself (no locality). 



The species, originally described from Swiss examples, and 

 subsequently (Berlin. Ent. Zeit. 1867, 377) recorded by Herr 

 L. von Heyden from Germany, is, according to Mulsant, 

 like E. Kai'steni, Reich., but distinguished from that insect 

 by its larger size, more flattened shape, and laterally more 

 dilated thorax.
