Calosoma calidum (Fabr.). - La-
brum very deeply cleft ; the sides of the cleft lined with long bristles. There are about 45 taste-cups on each side under
the base of the labrum. The cups are
papilliform, being rather high, with a
seta arising from each.
Cicindela hirticollis Say.-In a Flor-
idan example, the structure of the epi-
pharynx is singular; there are no
taste-cups, except a few on two large,
VARIATION OF
COLOR IN THE LAR-
VAE OF SPHINX GORDIUS.
In September, 1888, we found, in Nonquitt, Mass., feeding on sweet fern (Comjtonia
asflemfolia) and low huckleberry (Gay-
lussacia dumosa) five larvae of peculiar color- ing. The head was large, rounded, green, with face-lines of pale yellow-green, edged behind with black. Mouth-parts dark.
The body was 2 inches long, of a very dark olive-green overlaid with deep wine-color, especially on the back. It was very smooth in every specimen, and irregularly dotted with white points encircled with black,
except the anal shield, which was dotted with black.
There were seven white obliques, shaded
above with a little crimson, then edged with very dark wine-color.
Caudal horn was black with no side lines. Anal shield edged with light green.
Spiracles were red lines set in light green spaces, and inconspicuous except the first segment.
Feet red; props of body color, being
lighter on the under side.

We can find no mention of such coloring
in any of the books to which we have access, and it differs much from that of the ordinary larvae, of which we had fifteen or twenty. Ida M. Eliot, Caroline G. Soule.

PROCEEDINGS OF SOCIETIES.
COLORADO BIOLOGICAL ASSOCIATION.
REPORT ON ENTOMOLOGY -JAN., FEB.,
MARCH, 1889. -The membership now num-
bers 51 ; the following entomologists have joined during the past three months: Lord Walsingham, Mr. W. S. Foster, Dr. Geo, H: Horn, Mr. J. Jenner Weir, Prof. A. S. Pack- ard, Rev. C. J. s. Bethune, Mr. H: Edwards, and Mr. John T. Carrington.
The additions to the insect-fauna of Color- ado, recorded in the books of the association, round, raised areas, which are guarded
in front by a few very long setae. On
the surface of each area are numerous
very long setae which may if not tactile, have some other sense, as they arise from cup-like bases or cells. Those on the
outside are like true taste-cups, with a bristle but little larger than normal in taste-cups generally. I am disposed to
regard this sensory field as a highly
specialized gustatory aparatus.
are as follows: coleoptera, 118 and 2 vars; hymenoptera, 68; orthoptera, I; rhopalocera, 6 and 3 vars.< heterocera, 76 and 4 vars. ; homoptera. 5 ; heteroptera, 5; diptera, g and I var. ; arachnids, 3 and 2 vars. Several of the hymenoptera are undescribcd, but will be fully dealt with by Mr. Ashmead, who has in preparation a list of the hymenoptera of Colorado.
Nine reports have been published, contain- ing, anlong other entomological matter,
accounts of the tent caterpillar, the Colorado cabbage flea-beetle (PhylZotreta jusilla) , the thistle-bud fly (Scrz@otricha culta), the large flat-headed pine borer [Chalcofhora virginiensis) , and Euryomia inda.
The library has been enriched by numer-
ous additions, notices of which have appeared - -
" in the weekly reports.
A meeting was held at West Cliff on 29
Jan. : the secretary read a paper on ichneu- mons.
Owing to the time of year, but little field- work has been done, and our energies have been mostly directed to the identification and classification of specimens captured last year, Mr. Horace G. Smith, Jr., of Denver, has submitted a small but interesting collection of butterflies from Arapahoe co., to Mr. H. W. Nash, and among them he finds a $
Callidryas ffiilea L, which is new for Col- orado, and also an example of Paphia fro- glodyta, and one of Pafilio rutulm. Mr.
W. S. Foster has sent some valuable notes on his captures at Salida and in Marshall Pass, the latter locality being above 10,000 feet. Mr. H. W. Nash sends a note of the occurrence of Nisoniades aweus Edw., in
Pueblo co.
'Numerous species of insects have been
kindly examined and identified by Prof. C. V. Riley, Dr. Geo. H. Horn, Dr. John Ham- ilton, Prof. A. S. Packard, Mr. W: H.
Ashmead, Mr. W: H. Edwards and Lord
Walsingham.
