Notes on Collecting in Mexico. 



By J. F. McClendon, University of Pa., Philadelphia. 



In the summer of 1902, while seeking the cool plateau of 

 Mexico as a quiet retreat to pursue my studies, I found near 

 Guadalajara, Jalisco, some Neuropterous insects that were new 

 to me, and the next summer planned a trip to Jalisco to col- 

 lect insects and some other zoological specimens. Many of 

 the specimens I took have been used in preparation of the 

 Biologia Centrali- Americana, and at the request of Dr. P. P. 

 Calvert I give the following account of my trip: 



On June 12, 1903, I crossed the border at Eagle Pass and 

 reached Guadalajara by the Mexican International & Central 

 Railways. Most of the suburbs of this city are covered 

 by crops of corn and tobacco, but the ravine of the San- 

 tiago forms an admirable collecting ground for an entomol- 

 ogist, and here and in some deserted parks I spent most 

 of my time. The altitude and the frequent rains of this sea- 

 son made the air very cool and most of the insects caught 

 were nearctic, save at the bottom of the ravine, where, amid 

 oranges, bananas and other tropical plants, are found many 

 forms that have strayed from the hot shores of the Pa- 

 cific. The further down the river I went, the more tropi- 

 cal forms were met with, but as the natives were not in- 

 clined to be civil. I did not go further than the Barranca de San 

 Juan. One hideous night at that hacie?ida discouraged my 

 scientific zeal, and I preferred to lose a few hours on mule 

 back each day rather than repeat such an experience. I 

 went up in the mountains as far as Zapotlanejo, about 

 20 miles east of Guadalajara on horseback, and succeeded 

 in returning with some specimens. Although I did not
