erroneous attribution of Marsham's ruficollis to it as a synonym, L. rugicollis, C 
hirtus, Schiipp., and rugosus, Hbst., are also erroneously attributed to Britain 
Mannerlieim, apparently through Stephensian blunders (though rugosus has subi 
quently been found in this country). The same observation applies to Corticm 
longicornis, Hbst. (not in Wat. Cat. syn.), linearis, Payk., and similafa, Schiipp,

Note on the Heteromerous genus f'latestlies, 0. R. Waterli. {Ann. Sf Mag. S 
Hist., 1845, vol. xvi, p. 317). — M. Lacordaire, in his " Genera des Coleoptere 
Tom. V, p. 215, says that the insect which Mr. Waterhouse describes (silphoid 
is the same as that described by M. Guerin Meneville under the name Prcu 
depressa in the Revue Zool., 1841, p. 215. This is, however, a mistake ; Ihi 
both insects before me, and they evidently belong to quite distinct species, althoi 
to the same genus. The description of Praocis depressa will apply to Plated 
silphoides in every point, except that in depressa the elytra are said to be a Ii 
longer than broad, whilst in P. silp>Jioides they are decidedly longer. The tho 
in silphoides is very neai-ly as broad as (sometimes broader than) the elytra, 
disc being very thickly and strongly impressed with almost confluent punctur 
but in depressa the thorax is decidedly narrower that the elytra, the disc be 
sparingly and not deeply punctured. The elytra in the specimens of depressi 
the British Museum collection are inclined to fuscous. 
The dimensions of the two species are as follows : — P. silphoides, long. 5^ 1 
lat. 2i lin. ; P. depressa, long. 5i lin., lat. 3 lin. Both insects are from S. Patagoi

Note on Cleonus sulcirostris. — I took a specimen of this beetle to-day, upo 
dwarf-willow on the sand-hills here, and note the circumstance, as the insect li 
in thistles, so that willow would seem an unnatural habitat for it. — E. Kop

Early occurrence of Lyccena Argiolus. — To-day (exceptionally warm and sun 
I took a fine ? of this species. We consider here that last year the season ^ 
fully a month in advance, as compared with this ; yet the earliest date upon wl 
I then saw Argiolus was April 24th. — Alexander Nash, Hardwicke, Glouces 
Uh April, 1870. 
Note on Saturnia carpini. — One $ of this insect appeared on March 31st, 
one S this day (April 5th). Both had been two years in pupa. — Id. 
On the egg-state of Cirroedia xerampelina. — At p. 135, vol. iv of Ent. ffl 
Mag., I have given an account of all I ever had to do with this species, in the ^ 
of investigating its earlier stages ; but, although I cannot say much from my c 
knowledge, I possess a good deal of information about it, given me by 
late Mr, Edmunds, of Worcester. He claimed to speak from much experieno 
rearing it, and gave this as the result of his investigations— that he found if the e 
were kept at no higher temperature thau that prevailing out-doors, the larvaj wc
