covered by Mr. Henderson, of Glasgow. It is astonishing how snch a conspicuous 
species should have escaped the nets of the many collectors who frequent this 
locality ; some, indeed, having been specially on the look-out for it, as the late 
Mr. Walton once took it at Shirley in great quantity. Some idea of its numbers 
may be formed from the fact that I bottled upwards of 300 in less than an hour. 
Smicronyx cicur. Sihynes primitnts (not rare) and potentillce, both on sand. Ortho- 
chmtes setiger. Acalles ptinoides, very common in the pits, especially after a high 
wind, when the dead twigs in which it lives get broken off the trees. Ceuthor- 
hyncJius melanostictus, cntx, asperifoUariim, and cyanipennis. Gymnetron hecca- 
bungw, var. veronicce, not uncommon in the. pits. Hylastes cunicularms, in the pits, 
especially to be found after wind ; H. ater, &c. Phlwophthorus rhododactylus. 
Tomicus micrographus, laricis, and hidens. Crepidodera ventralis. Phyllotreta 
nodicornis * and lepidii. Thyamis nastnrtii, lycopi, alyricapilla, and fuscicollis. 
PsylUodes hyoscyami. Cassida nohilis. Snjmnii^s frontalis, capitatus and discoideus. 
Alexia pilifera. Bythinus puncticollis. 
My journeys have chiefly been hurried, and somewhat late in the evening, 
after office hours, so that I can lay no claim to having properly worked the locality, 
— the bulk of my captures having indeed been " flukes." It may, however, be 
guessed from the above list (in spite of its containing nothing very startling) that 
Wickham and its neighbourhood ai'e well worth visiting. — E. C. Rye, 284, King's 
Road, Chelsea, S.W., JvAy, 1867. 
Note on some species of Ceuthorhynchus frequenting Sisyynhrium officinale. — The 
arid and uninviting aspect of this plant, — which, when rather old, looks like nothing 
so much as a loose handful of straight wires, — and its habit of affecting the dustiest 
and most unHkely places, such as road sides and old brick fields, probably prevent 
many young Coleopterists from paying such attention to it as it deserves ; at least, 
I judge so from the absence, or great rarity, in most collections of certain species 
of Ceuthorhynclms wliich are to be found upon it. Of these, C. chalyieiis is by far 
the most common, and seems to occur wherever the plant is found, often in great 
profusion. With it I occasionally get C. cyanipennis (readily disting-uished by its 
larger size and flatter interstices, and the light-coloured penultimate joint of its 
tarsi), though that species is more abundant on Erysimum alliaria. Neither of 
these insects is common in ordinary collections ; but there are two other species, 
also to be found on Sisymbrium, which have hitherto been of the gi-eatest rarity. 
One of these, the C. inaffectatus of Walton and others, now definitely determined 
to be C. rapce, Gyll., — inaffectatus being a nonentity, — has appeared sparingly in 
our cabinets, having been taken by single specimens at different times (and 
fortuitously) by Mr. Pelerin, to whom most London Coleopterists are indebted for 
it. It has also been taken by Messrs. S. Stevens and F. Smith. Mr. Waterhouse's 
sons afterwards took it sparingly at Tottenham, — still without its food-plant being 
discovered ; and I have myself in vain visited their locality for it. Since then, 
Dr. Sharp found one or two examples at Lee on Sisymbrium (not unaccompanied 
by the pestiferous C. assimilis), and one in his own garden at St. John's Wood ! 
Dr. Power also found the insect at Dr. Sharp's locality ; and, after a year's 
interval, or more, I also took it there, accompanied by the rare C. constrictus.
