PS r CHE. 



[May— July i8S9- 



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, 



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. 



VARIATION OF COLOR IN THE LAR- 

 VAE OF SPHINX GORDIUS. 



In September, i88S, we found, in Nonquitt, 

 Mass., feeding on sweet fern {Comptonta 

 asflenifolia) and low huckleberry (^Gay 

 lussaci'a diimosa) 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 stnooih 

 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. 



On June i6th, 1S89, one of the pupae 

 formed by these larvae gave Gordtus $ . 



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.

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, 



are as follows: coleoptera, 118 and 2 varsj 

 hymenoptera, 68; orthoptera, i ; rhopalocera, 

 6 and 3 vars. ; heterocera, 76 and 4 vars. ; 

 homoptera 5; heteroptera, 5 ; diptera, 9 and 

 I var. ; arachnida, 3 and 2 vars. Several of 

 the hymenoptera are undescribed, 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, among other entomological matter, 

 accounts of the tent caterpillar, the Colorado 

 cabbage flea-beetle {Phyllotreta pusilla), the 

 thistle-bud fly {Serif totricfia ciilta), the 

 large flat-headed pine borer {Chalcophora 

 virginiensis), and Eiiryotnia 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 fhilea L, which is new for Col- 

 orado, and also an example of Paphia tro- 

 glodyia, and one of Papilio rntuliis. 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 t)ie 

 occurrence of Nisoniades alpheiis 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.
