collector, but after getting on to their ways they can be taken 

 by hundreds. Ageronia also have a habit of sitting on lichen- 

 covered trees, and are very hard to see at a distance of only a 

 few feet. 



I left Altamira the latter part of July, and started for San 

 Luis Potosi, by way of Tampico. After leaving Tampico the 

 road passes through low-lying country, grown to small timber 

 and brush. In this part of the country there is a great abund- 

 ance of flowers, and here I saw more specimens than during 

 any other part of the trip. The species were mostly confined 

 to the commoner ones, but there were some fine Papilio and 

 other species. As the train would pass a water-hole the ' ' flies ' : 

 would rise in great clouds and beat against the car-windows. 



As the road gradually reached higher ground, the vegeta- 

 tion and insect-life became more and more scarce until, at an 

 altitude of 5000 feet, only a few Hesperidae and other small, 

 hardy 'flies" were to be found. On the way up Rascon 

 Mountain I saw one Ithomia and one Morp/io, the only ones 

 seen on the trip. 



At San L,uis Potosi there is very little to be had of entomo- 

 logical interest, and what there is is confined to the plazas, 

 and the fields close to the irrigation ditches that come to the 

 city from the dam situated some six miles to the west. 



Here I took a number of Papilio daiuius, cresphontes and 

 philcnor, and a few Lycatna, besides a good number of Odonata 

 and a few Hymenoptera. 



At a siding on the Mexico Central Railway, about fifty miles 

 east of San L,uis Potosi, there is a small valley that evidently 

 gets a large supply of rain, and here I took a large number of 

 Papilio, Eurcinn in>\\icana and a number of other " flies " not 

 yet identified, besides a large number of species of Orthoptera 

 and a few Odonata. 



I left San L,uis Potosi the last of August and went to Saltillo 

 over the Mexican National Railway, but aside from a wreck, 

 the trip was devoid of interest, for the road passes through a 

 high table-land that is dry and barren. 



From Saltillo I went southwest about 130 kilometers to the 

 mining town of Concepcion del Oro, and there took mules,
