36 Unizcrsity of Michigan 



rina macropus and capitalis common, and miniata very rare. 

 Below the intake capitalis was not found, but caja appeared 

 commonly there, macropus was in smaller niunbers, but still 

 common, while miniata was ver\- rare. 



On the Poquera River, south of town, we found only caja 

 and macropus, both common and in about equal numbers. 

 The Poquera at this date was five to fifteen feet wide, in a 

 wider, more sun-exposed bed than the San Juan. The water 

 was low when we were there, and we were told that it some- 

 times became entirely dry. 



29. Morales, Guatemala. A station on the railroad 33.6 

 miles above Puerto Barrios. Elevation estimated at about 100 

 feet. A large, sluggish stream here was too deep and with 

 banks too brushy for effective collecting, and the only Hetae- 

 rinas taken were five specimens of titia. Collected ^lay 2/, 

 1909. 



30. Xirgiia, Venezuela. Conditions similar to Bejuma, but 

 the country^ rougher and, adjacent to the town, more despoiled. 

 The Rio Borria, at the foot of the plateau on which the town 

 is built is eight to twenty feet wide, and a few miles above 

 town is in such a deep, rocky gorge with high waterfalls and 

 deep pools that it is impossible to follow the stream. Above 

 the intake for the city water supply, where it flows through 

 brush and small trees, the stream is six to twelve feet wide 

 and is gravelly and not very swift. Three or four miles north 

 of town is a typical hill quebrada in pastures, brush, and coffee 

 and banana plantings. On the top of the hill, above nuining 

 water, is a humid forest. A similar small quebrada is about 

 four miles northeast of town on the road to Bejuma. Ele- 

 vation of Nirgua not learned, probably 1,500 to 2,000 feet. 

 Collected February 25-29, 1920.
