APPENDIX SS. 1847 



NOTES ON THE ORTHOPTERA. 



No. 1. Numerous at and about Pagosa Springs. 



Nos. 2, JJ, 4, 5, and 6. Same. 



No. 7. This species of the Aerydii was abundant on some of the grassy bottom-lands along the rivers 

 in parts of July and August, and was particularly useful in supplying the morning table, being highly 

 prized by the large-sized speckled trout (S. fontinalis) of the rivers. It is peculiarly aggravating to a 

 lover of sport to find that his fine Scotch or English flies are, for a few weeks of the season at least, but 

 of little value, and that the ordinary "cattle boy" can have almost as good "luck" with sometimes a 

 manufactured hook and home-made appliances, capturing his bait near the river-bank, as he with his 

 imported and costly rods and fishing-tackle. With the passage of the hottest summer days, the trout 

 lose their liking therefor, and artificial flies, as a novelty, can be strongly brought into play with general 

 good results. 



Nos. 8, 9, 10, 11, and 12. Same note as to No. 1. 



No. 15. Numerous in the valley of this and the Navajo, and also on "Weeminuche Creek, a large trib- 

 utary of the Piedra. They were more frequently observed in the early morning than at any other time. 

 As we rode along the trail, through the high-grassed valley, with the morning sun scarcely over the 

 mountain tops, they could be seen upon every side, dropping on the approach of the train from their 

 look-out stations upon a blade of grass. 



No. 16. Numbers observed. Altitude. 9,000 feet. All the large trout (S. fontinalis) i were at this time 

 in this altitude or vicinity, being taken plentifully every evening, and all of good size, with this and 

 other large orthoptera as a bait. 1,200 feet down, near Camp 45, all trout were small. 



Nos. 17 and 18. Plentiful. 



No. 19. Species similar to No. 16. Lost in transit. 



No. 20. Very numerous in this valley. 



No. 21. Specimen similar to No. 20. Lost in transit. 



No. 23. Same as No. 20. 



No. 24. Same as No. 20. 



Nos. 23-48. "Were taken along a stream tributary to the Vallecito. at an altitude of 10,000 feet. The 

 region was a mass of quartzite rocks, strewn everywhere along the track of the water, up which we had 

 to hug our way to find a foothold, cutting the trail as we went. Coming upon a small patch of high 

 grass on a "bench" by the river, an isolated spot amid rocks and fallen timber, the place was so covered 

 with almost a cloud of orthoptera that it was a subject of remark by every one. 



Nos. 49-61. These specimens were taken on top slopes and grassy places of the crags above Camp 52, 

 the highest camping place but one occupied during the entire trip. They are interesting from the fact 

 of their occupying an altitude of over 12,000 feet, and some nearly or quite 13,000 feet. This was a con- 

 siderable height above timber-line and in the region of the strictly Alpine flora. 



No. 64. None of these were taken in the lofty elevations where were those numbered 49-61. 



No. 67. Frequently seen in this vitunity. 



No. 74. Seen often during marches along the Rio de los Pinos and Pio Florida. 



No. 75. Observed also along the San Juan and Los Pinos Pivers. 



No. 76. This specimen was similar to No. 74. Lost in transit. 



No. 77. Plentiful in bottom-land near the River Rio Grande. 



No. 79. Numerous on plain or mesa bench above the River Florida, in the immediate vicinity of the water. 



Nos. 80, 81, 82, and 83. Same remarks as above. 



No. 86. More observed here than at any other point along the river. 



No. 87. Abundant in the most fertile localities along this river and others traversed during the last 

 month, as the Rio Piedra, De los Pinos, &.c. The peculiar color of the wings of this species of the Aery- 

 dii makes it easily distinguishable and perhaps more readily observed on the march than any other. 



No. 97. Very numerous in the bottom-lands along this part of the river valley.

LEPIDOPTERA. 



By Prof. Herman Strecker. 



Letter of transmittal. 



Reading, Pa., August 9, 1878. 



Sir : I transmit herewith a classified list of the Hymenoptera, Lepidoptera, and Coleop- 

 tera collected by yon in Southwestern Colorado and the adjoining border of New 

 Mexico during the San Juan reconnaissance made under your charge in 1877. With 

 a few exceptions, which I have designated, the examples are all from Colorado. 



A few reptiles were sent to me along with the collection of insects, these I have 

 identified and classified at the end of this paper. 



The collection of Lepidoptera is very rich, including a number of rare and new species ; 

 prominent among the former are the aberrant $ examples of Argynnis Nokomis, the 

 beautiful MelitceaAlma, the second known example, and Hemileuca Juno, the only exam- 

 ples of which previously known were taken by Dr. Palmer on the borders of Arizona, 

 and are now in the museum of the Department of Agriculture. 



The LTeteroceres were rich in new species, there being no less than eleven, most 

 of them being more or less conspicuous for beauty, these I have figured on the accom- 

 panying plates; prominent among them is the superb Ctenuclia Sanguinaria, the most 

 splendid of its genus yet found in North America. 



Among the Coleoptera are some rare species, but none new. 



In the Hymenoptera are several rare and one new species, the latter a Smicra, which I 

 have herein described. 



For aid in determining the Hymenoptera I give thanks to Mr. Ch'as. A. Blake and E. 

 T. Cresson, for the Coleoptera to Mr. A. S. Fuller, and for the Iteptilia to Mr. John Ryder. 

 Very respectfully, yours, truly, 



Herman Strecker. 



Lieut. Chas. A. H. McCauley, U. S. A., 



In charge of the San Juan Reconnaissance, Fort Leavenworth, Eans.
