18. Hypocyptus NiGRiPES, Stephens, 111. Mand., v, p. 188; 



Pandelle, /. c, p. 284 ; E. C. Rye, /. c. vol. vi, p. 210. 



M. Pandelle identifies 'pygmcBUS, Ktz., with this insect, of 

 which he sinks it as a synonym. But Stephens' insect is 

 H. longicornis, V^Lyk.j and in its description in the *' Manual'^ 

 (where it is referred to IceviusculuSy Mann.) is stated to have 

 the hinder ano;les of the thorax very straight, — a definition 

 which does not agree with the characters oi 'pygmceus. 



19. Tachyporus tersus, Er., Gen.et Spec. Staph., p. 237; 



Ktz., Ins. DeutschL, ii, p. 425 ; Pandelle, /. c, p. 301 ; 

 E. C. Rye, I c, vol. vi, p. 211. 



The T. tersus of Wat. Cat. (common at Lee-pit, on Barnes 

 Common, and elsewhere in the London district) appears not 

 to be the insect known by that name to M. Pandelle, but to 

 be as yet apparently undescribed ; M. Fauvel, indeed, some 

 time ago informed me of his intention to publish a description 

 of it under the name sciitellaris. Its very light stiaw-colour 

 and abrupt triangular black scutellar patch render it abun- 

 dantly distinct from all our other species, and its want of a 

 black lateral margin at once prevents it from agreeing with 

 the descriptions of tersus. Dr. Sharp, however, has given 

 me specimens from Croydon as identical with M. Pandelle's 

 tersus, but not seeming to agree quite satisfactorily with 

 Erichson's description, which states tersiis to be like chryso- 

 melinus, but smaller, narrower, less convex, with a shorter 

 thorax and proportionately rather longer el3'tra (his note is 

 contradicted in that respect by his description), which are 

 more obsoletely punctured, and the mouth black, except in 

 its lower portion (here again the note and description dis- 

 agree).
