development, did not shake (on the contrary, rather strengthened) my belief in - 
as a species ; but I have recently seen a British specimen belonging to Dr. Shar 
one side of the thorax of which is that of normal acutangulus, and the other mor 
than intermediate between that species and Waterhousei, Abandonod as a species 
I presume the British origin of the individual will not again be questioned.—Ip. 
Note on the habits of Dorcatoma boviste, Ent. H.—In September last, my frien 
Mr. Linton and I found the larva of this species in small dry specimens of Bovistc 
plumbea and other small fungi, on a sandy flat near Barmouth. 
Tn less than a week, several perfect specimens of the Dorcatoma made their 
appearance ; others have since continued to do so very sparingly, and, as the fungi 
still contain larva, other specimens may come out next spring. Sometimes the 
larva eats its way out of the fungus, and at once changes into the pupa state, from! 
which it becomes the perfect insect in about ten days ; but usually it forms a cocoon 
of spores, changing to the pupa state inside the fungus, out of which the perfect; 
insect eats its way. 
We found the Bovista in all stages of growth, from the size of a pea to the old 
dry specimens in which were the larva ; but there were no traces of larvee in any 
of the fresh fungi, although it seems most probable that eggs had been laid and 
hatched in some of them; probably the lary. were too small to be easily discovered. | 
I was directed to the place where we found the fungi by Mr. J. Kidson Taylor, 
whose original capture of the Dorcatoma at Barmouth bas been recorded in this | 
Magazine. The species appears to be very local, as fungi picked up in other places 
in the neighbourhood contained no trace of the insect.—J. SrpEBoTHaM, 19, George 
Street, Manchester, 11th November, 1871. 
Note on Nemosoma elongata.—Having, some years ago, met with a few dead 
examples of this species in an old rail near Beeston, Notts., I determined, as I was j 
staying for a few days in the same neighbourhood during this wee., to find the — 
insect in a living state, if possible. An examination of a few elm rails in the 
meadows near the Trent soon produced a few specimens, along with their constant — 
companion, Hylesinus vittatus. 
~ Qn naming the matter to my friend Mr. E. J. Lowe of Highfields, I asking him 
where it was probable I should meet with more elm rails, he suggested that I 
should examine the wood yard behind his garden. We accordingly did so, and I | 
soon found a considerable number of specimens, leaving many logs and rails un- 
touched.—Ip. | 
On Pezomachus trua, Forst., and P. fasciatus, Fab., g.—At p- 162 of this vol., I 
stated that the male insects sent by Mr. Fletcher were Hemiteles tenuicornis, Gr., 7 
according to Mr. Desvignes. Three specimens named by Mr. Desvignes have 
always stood unquestioned in my collection under that name ; and they are cer- { 
tainly identical with Mr. Fletcher’s specimens. But examination of them by the q 
descriptions of Gravenhorst and Taschenberg, shews that they cannot be H. tenui- ~ 
cornis ; of which the g 9 are both known, winged, and with the metathorax _ 
areated. I regret to have been led into error by accepting this name without 
examination. The result of a careful search into the nomenclature of these 
insects may be thus briefly expressed :—Pezomachus trum, Forst, ? ,= hortensis, Gr.,
