have occurred in nature, as the specimen was suspiciously fresh, and I 

 have found a wasted specimen, on a previous occasion, to lay freely. 



Plus 1 A moneta. — A cocoon of this species sent to me from a 

 garden at Ewell, produced a moth on July 2nd, and three days later I 

 netted a wasted male specimen at Reigate, from Silene injiata. 



Smerinthus ocellata. — A few ova of this species were found l)y 

 searching sallow leaves, on June 13th, hatched two days later, fuU-feil 

 about July 21st. 



Nemeobius lucina. — Ova laid by captured $ , June 10th, hatched 

 June 25th, one of the resulting pupae, a ? , produced a butterfly on 

 August 22nd, the other pupn? hybernated as such. — R. M. PRiDKArx,

Hydrovatus clypealis, Sharp, in the Isle of Wight. — ^I have 

 much pleasure in recording a new locality for this very local and rare 

 insect, it turned up (apparently m some numbers) near Sandown, on 

 April 22nd and 23rd, and half an hour's work enabled me to secure a 

 nice series and a few duplicates. It will be remembered that it was 

 one of Mr. Moncreaff's captures; that gentleman found it abundantly 

 near Portsmouth, but, as far as I know, except for one or two stray 

 captures in the New Forest, it has never been found until now out of 

 the Portsmouth district, and has not, apparently, been captured for 

 many years. It is a pretty little insect and very distinct, so there is 

 not much risk of its being passed over, its very short front legs render 

 it a very troublesome insect to set neatly. — (Professor) T. Hudson

Huebner's "Tentamen." 



By J. W. TUTT, F.E.S. 

 Probably one of the most-abused and most-discussed publications 

 (;hat have to be considered by those who have tackled the question of 

 the synonymy of the lepidoptera is Hiibner's Tentamen. Possibly 

 this resulted from two causes ; (1) Its rarity, so few copies being 

 available for reference when synonymy began to be considered under 

 the present opposed methods. (2) The difficulty of fixing the date of 

 its publication, which Scudder and others have since authorita- 

 tively settled was in 180G. Scudder, some years ago, reprinted the 

 Tentaiiien from the copy in the Berlin Museum, we believe, and 

 Scudder's reprint is in general use for reference, but even this is so 

 rare, that workers at South Kensington are indebted to the courtesy 

 of Sir George Hampson for reference to a written copy in his possession. 

 It was, therefore, with much pleasure that I recently discovered, bound 

 at the end of a copy of vol. iv. of OchFenheimer and Treitschke's 

 Die Schntetterlinge von Knnqm, a set of which work I had purchased, 

 an original copy of Hiibner's Tentamen. Ochsenheimer refers to the 

 publication of the Tentamen in his preface to this volume of Die 

 Schmett, von Eiiropa, and, in the synonymic paragraphs, one finds 

 unfailing reference to those species which Hiibner has mentioned in 

 his publication. With the idea of showing our readers Hiibner's views 

 of the classification of the lepidoptera as set forth in the Tentamen^ 

 we give a copy of the work, which, however, was issued as a quarto 

 sheet. The columns are arranged exactly as in Hiibner's paper.
