COLEOPTERA OF THE LOWER RIO GRANDE. 



107 



greenish, legs tending to brownish or piceous. No Mexican 

 specimens of A. oblongopiinctata are at hand for comparison, 

 the identification being made from description alone. The 

 type came from the vicinity of Vera Cruz, Mexico. 



Ega sallei Chevr. Swarming on the wet banks of sloughs 

 all around Brownsville in June and July. This curious little 

 beetle bears so great a resemblance to an ant, when in motion, 

 that an inexperienced collector might readily be deceived. 

 North to San Antonio. 



Tetragonoderus latipenxis Lee. Laredo, one speci- 

 men, July 24th. At Columbus this was perhaps the most 

 abundant Carabid during my visit there in 1892, but on ac- 

 count of its peculiar coloration rather difficult to detect on the 

 sandy banks which formed the favorite habitat. 



T. fasciatus Hald. Three or four at Laredo under vines 

 near river. Rather abundant at Columbus and fully as well 

 protected by its coloration as the preceding species. Found 

 as far north as Indiana, west and south to xArizona and Baja 

 California. 



Lebia grandis Hentz. Rare in June and July, among 

 herbage or in tree-moss. Widely distributed, going north to 

 Canada and Massachusetts, west to xArizona and Colorado; 

 not uncommon in Iowa. Also in Townsend's collection. 



L. bit^eniata Chevr. Rare in July; Mr. Schwarz took it 

 in June. Occurs also in the state of Tamaulipas, Mexico. 



L. viridis Say. Rare, Jul}'. One of our most widely dis- 

 tributed Carabidag, occurring, as Dr. Horn has remarked, 

 from Maine to Oregon, and south to Guatemala. It also in- 

 habits Canada. 



L. rhodopus Schwarz. Rare on vines in July. If this is 

 in reality a variety of the preceding species, it is certainly very 

 well marked. Found in Florida. 



L. viridipennis Dej. Rare, in July. Extends north to 

 Canada.
