CERYLON. 



The following species is closely allied to some of the European 

 members of the genus Gerylon, which gsnus in Lacordaire's 

 classification belongs to a "Tribe" of the Colydiidce that has not 

 — so far as I know — been previously reported as Australian. 

 {^. alienigenum, sp. nov. Minus convexum, sat latum (forma fere 

 ut G. ferruginei^ Steph.) ; obscure ferrugineum, prothorace 

 piceo ; nitidum ; antennis (fere ut Q. ferruginei, sed clava 

 breviori latiori) sat robustis, articulis 2° 3" que brevibus 

 capite subtilissime punctulato ; prothorace subquadrato, 

 supra quam ferruginei minus forfeiter minus crebre punc 

 tulato, ad basin utrinque profunde impresso ; elytris punc 

 tulato-striatis, striis profundis versus apicem (subsuturali 

 excepta) obsoletis (subsuturali antice abbreviata, 2^^ 4^" basin 

 attingentibus, b^ 6" que antrorsum parum ultra medium pro- 

 ductis, interstitiis latis planis vix perspicue punctulatis ; 

 sternis et segmento basali ventrali ad latera grosse sparsim 

 punctulatis ; hoc in medio oblique bistriato (fere ut Diphylli). 

 Long., 11.; lat., f 1- 

 Like the European C. ferrugineum, Steph., in form and color 

 •except in the prothorax being considerably darker than the- 

 elytra. The pronotum (compared with that of others known to 

 me of the genus) is less strongly and less closely punctulate. The 

 fifth and sixth striae of the elytra are very short.

PROSTOMIS. 



The members of this genus (especially males) seem to be rare 

 in collections, and the species are closely allied infer se. 



P. Atkinsoni, Waterh. I have taken in Tasmania (and have 

 received from several Tasmanian correspondents) a Prostomis 

 which I presume to be this species. I cannot say that it agrees 

 very exactly with the description ; but weighing in combination 

 the two facts — that I have seen no other Prostomis from Tas- 

 mania and that this particular one is the only Prostomis I know 

 with the puncturation of the head and pronotum very fine (a 

 character which its author attributes to P. Atkinsoni) — I do not 

 see much room for doubt. The principal difierences are as 

 follows : — Waterhouse calls the sides of the prothorax " vix 

 arcuatis," whereas in the species before me they are certainly 

 more rounded (especially in the male) than that expression makes 

 them ; Waterhouse's sexual distinctions do not fit the species 

 before me. I have two specimens taken under the bark of one 

 tree which I cannot doubt are male and female of a single species 

 — one of them, which I have no doubt is the male, is Long., 4|- 1.
