stomus, Grav. There are four of the latter in the collection, but 

 I hesitated to select a type. 



C. (Helictes) cruentatus = Megastylus cruentator, Schiod. — 

 Type selected by me from a series of nine Irish specimens ; not 

 indicated by Haliday. 



C. {Helictes) varius. — Type not indicated nor selectable ; the 

 description leaves little room for doubt that it is closely allied to 

 Helictes coxalis, Forster. 



Clepticus.— Eespecting this genus, I was able to determine 

 nothing. 



Plectiscus, Pimpla (Ephialtes) senator. — Type not indicated. 



Pimpla (Polysphincta) phanicea. — Owned by Haliday to be a 

 form of P. percontatoria, Mull. 



Acrodactyla madida. — Type (a dissected female) selected by 

 me from nine examples of both sexes ; not indicated by Haliday. 



A. degener. — Type similarly selected from seven examples of 

 both sexes. 



Bassus serricomis, Euceros serricomis = E. egregius, Holmgr. 

 = Bassus peronatus, Marsh. A single pair, of which the female 

 is the type, simply labelled " serricomis." 



B. (Orthocentrus) laricis. — '■ Correctly synonymised with 

 Stenomacrus fortipes, Thorns, in Ichn. Brit. Type not indicated. 



Porizon linguarius. — Type neither indicated nor selectable ; 

 P. moderator and P. dissimilis are the only species of the genus 

 named by Haliday. 



Atractodes, Grav. — Of this difficult genus are nearly two 

 hundred specimens in the collection. 



A. incessor = Exolytus Icevigatus. — Type labelled " incessor." 



A. dionceus. — Type not indicated ; probably a form of the 

 last. 



A. scrutator = E. Icevigatus. — Type labelled " scrutator." 



A. vestalis. — A very long series; type labelled "vestalis." 

 The species is now known as toiebricosus, Grav. 



A. albo-vinctus. — This species is not now contained in the 

 collection at all. 



A. arator. — Type specifically labelled. 



A. salius. — Type not named, and cannot now be fixed. 



A. exilis. — Type not named nor selectable with certainty; 

 sexes appear transposed. 



A. croceicornis. — Type labelled with the MS. name " simu- 

 lans." 



A. piceicornis. — Type not named, and cannot be fixed. 



A.fumatus. — Type labelled specifically. 



A. cultellator =foveolatus, Grav., which latter Haliday mis- 

 understood. A solitary female, carded, unlabelled. 



A. citator. — Type not to be fixed. 



A. properator = Callidiotes (Mesatractodes, Mori.), luridator, 

 Grav. = coxator, Grav.
