p. 51 ; Staudinger refers the insect as a variety to Alamestra Leineri of Ireyer (N. 
B. 184, 3). It may be worth searching for on our Eastern coasts, where Artemisia 
maritima grows freely. — H. T. S.] 
Coccyx Ochsenheimeriana near Thetford. — I have met with six more specimens 
of Coccyx Ochsenheimeriana here lately among Abies cephalonica. Their habit 
appears to be to fly about 4 o’clock in the afternoon in the sunshine, at the ends of 
branches of the above-named fir. 
I rather hope to breed them another year from the cones, if, as I fancy, their 
habits are similar to those of C. strobilana. It is a beautiful little species, but very 
scarce. I have worked many days for them lately and have had men looking for 
them for the last three weeks, with only the small result which I have mentioned. —

Argyresthia cerariella ( Stainton , Ent. Ann., 1871,^- 100, and 1874, p. 25) bred . — 
From larvse collected last August at the Brushes, near Manchester, feeding in the 
berries of mountain ash, I have just bred a series of Argyresthia cer arietta. Plenty 
of A. conjugella are emerging, but no intermediate forms have yet appeared ; cerariella 
is certainly a species, the males and females copulate freely, but never yet have been 
observed to do so with conjugella. I am sorry to say that this insect is not likely to 
be abundant. — J. II. Threlfall, 4, East Cliff, Preston : June 2nd, 1880. 
Discovery of the icinged form of Prosopistoma punctif rons. — On the 7th inst. 
I received a hurriedly-written post-card, dated the 5th, from Dr. Emile Joly, of 
Marseilles, announcing the fact that his colleague, M. Yayssiere, had just shown him 
a bred sub-imago of Prosopistoma punctif rons, which proved to be one of the 
Ephemeridce, of small size, with four wings and three caudal setae. Thus, the per- 
sistent energy of Prof. N. <Toly and his son, and of M. Vayssiere, has solved a mystery 
that has existed since 1762, when G-eoffroy first described the aquatic condition as 
“ Le Binocle it queue en plumet,” which subsequently found itself located by Latreille 
in the Crustacea, under the name Prosopistoma punctifrons. The entomological 
public awaits with natural impatience fuller details of this most interesting dis- 
covery. — B. McLachlan, Lewisham, London : 18 th June, 1880. 
The generic name Pachymerus in Uemiptera. — In vol. xvi, p. 260, I said that 
“ Pachymerus is not available in llemiptera, unless it can be shown that Latreille 
and Amyot and Serville were in error.” 
Dr. Puton replies (Bull. Ent. Soc. France, No. 8, 1880, p. 83) by repeating his 
former statement that Pachymerus, Lep. et Serv. {llemiptera) , has priority over 
Pachymerus, Latr. (both dated 1825), because it is cited by the latter author, and 
this, notwithstanding, he has just before, in the same work, used the name for a 
genus of his own ; and Dr. Puton further says that Amyot and Serville were mis- 
taken as to dates, and accepted as pi’ior a name which at the time (1825) was un- 
published. Now, I put the matter hypothetically, because I gave Latreille credit 
for knowing what he was about, and was only employing a name he had previously 
brought into use ; and I naturally believed that Amyot and Serville also were sure 
of their statement concerning the priority of Latrcille’s genus and their consequent
