216 THE ENTOMOLOGIST. 
Head with usual transverse depression, and a small fovea in 
place of the longitudinal sulcation ; antenne long and slender, 
reaching below the middle of the elytra; the sides of the thorax 
margined and bisinuate at the middle; transverse depression of 
the elytra fairly well marked. Hasily distinguished by the shape 
and light colour. Judging from the description these three forms 
seem allied to nigritarsis, Jac., which I have not seen. 
Rhabdopterus, Lef. 
The history of 2. piceipes, Oliv., has been reviewed by Dr. 
Horn in ‘ Trans. Am. Ent. Soc.,’ vol. xix, p. 226; the species was 
described originally as coming from Carolina. I have a series of 
specimens marked ‘‘ Louisiana, A. Salle,” the ?’s of which I © 
find very difficult to reconcile with Dr. Horn’s description. They 
agree a good deal better with the original description of piceipes 
than they do with Say’s description of pretaxta. This, however, 
is only a suggestion, but I wish Dr. Horn had seen my specimens. 
Mr. Jacoby, in his paper on the Coleoptera of St. Vincent, 
in ‘ Trans. Ent. Soc. London,’ 1897, p. 257, gives piceipes as one 
of the list. In his second collection, part of which is in my 
possession, these St. Vincent specimens are named (his original 
label) piceipes, Oliv. ?; it is evidently a different species from our 
form, there is no sinuation to the hind tibia of the ¢ and the 
size is greater—lI call it grenadensis. Mr. Blatchley has sent 
from Dunedin, Florida, ten or a dozen specimens as piceipes, 
which are evidently not, as the hind tibia of the ¢ is strongly 
dilated at its apical half, and the form is larger and stouter. I 
call it blatchleyt.

NOTES AND OBSERVATIONS. 
Wartson’s ‘“SpeeRA’’ BinocunaAar MacGnirier.—Messrs. W. 
Watson & Sons, Ltd., of 313, High Holborn, have recently brought 
out a new magnifier, which will be of great assistance to entomolo- 
gists in dealing with small insects. There have been various devices 
invented in the past for this purpose, but the one I am discussing is 
far in advance of any I have seen for utility in pinning and setting 
small insects. It consists of a pair of binocular achromatic lenses, 
mounted in spectacle frames, and set at such an angle to each 
other that the vision converges on the focal point. The magnifiers 
are made in three powers, the focal lengths of the pair of lenses 
being 5, 7 and 10 in, giving magnifications of 3:5, 2°5 and 1:75 
diameters respectively. The cost is £2 per pair. The great advan- 
tages about the magnifiers are that they leave both hands free, they 
suit all sights, and if higher magnification is required, this can be 
obtained by holding an ordinary lens in the hand at focal distance 
from the object looked at. Anyone wishing to avail themselves of
