COLEOPTERA OF THE LOWER RIO GRANDE. 



113 



low wet banks of resaca near Brownsville. It is easily pro- 

 cured by pouring water on the bank, thus driving it from the 

 burrows. Takes flight almost at once on leaving shelter. 

 Known only from Texas, and hitherto very rare in collections. 



Agonoderus lineola Fabr. Only one specimen, smaller 

 than usual and less distinctly marked. Of very wide distribu- 

 tion. 



A. pallipes Fabr. One specimen; also a very common 

 and widely distributed insect. 



A. pauperculus Dej. Not common, inhabiting damp banks. 



Harpalus nitidulus Chaud. One specimen secured dur- 

 ing July. "Southern and Western States, Kansas." 



Selenophorus palliatus Fabr. El Sauz, June; common 

 in September at Brownsville, (Armstrong). Also from Town- 

 send. Recorded from Florida to Southern California. 



S. fatuus Lee. Common in July. I found it chiefly under 

 rubbish in the low lands adjoining the river. Taken also by 

 Mr. Townsend. 



S. perpolitus Casey. Rare under old yucca trunks in 

 July, on the high ridges between Brownsville and the Gulf. 



Stenolophus spretus Dej. One specimen, July. 



Bradycellus rupestris Say. In Mr. Townsend's collec- 

 tion. Said by Dr. Horn to occur over the whole of North 

 America except Alaska and the Hudson's Bay region. 



HALIPLID^. 



Haliplus ruficollis De Geer. Two specimens, doubt- 

 fully referred to this species, were taken in July. They are 

 larger than any of my northern ones. A specimen of Hali- 

 plus is included in Townsend's collection. 



Cnemidotus 12-PUNCTATUS Say. Found in July. Common 

 northward to Canada.
