COLEOPTERA OF THE LOWER RIO GRANDE. IO - 



T. corruscus Lec. Brownsville. June. Illinois. Pennsyl- 

 vania. 



T. vivax Lec. Not rare in July. This and all the other 

 species of Tdchys were identified by Dr. Horn. 



Pogonus tex anus Chaud. A large colony of this hitherto 

 very rare species was found under a palmetto log stranded on 

 a mud-flat at Point Isabel. The beetle is remarkably active 

 and the specimens displayed a degree of quickness in escaping 

 rarely surpassed among the Carabidae. The difference in fa- 

 cies in the genus Pogonus is quite remarkable, texanus bear- 

 ing a close resemblance to certain Amarce, while the other 

 North American forms are more like Agonoderus. Probably 

 P. texanus will prove to be a maritime or salt marsh species. 

 No specimens are known to have occurred outside of Texas. 



P. lecontei Horn. Obtained bv Townsend. Schwarz and 

 myself. It was not rare under drift-wood on the beach at 

 Point Isabel in June and July. Found also near Great Salt 

 Lake, Utah. 



Pterostichus texanus Lec. Apparently very common 

 during September. A great number were received from Mr. 

 Armstrong. 



Badister micans Lec. Brownsville. Mr. Schwarz. Re- 

 corded from Massachusetts. Florida and Georgia. 



Platyxus texanus Lec. Several specimens were sent 

 by Mr. Armstrong as having been collected during Septem- 

 ber. Also in Townsend's collection. 



Casnonta pennsylvanica DeGeer. Brownsville. July, in 

 cotton-held. Laredo. July 24th. under vines near river. Com- 

 mon in Iowa, extends north to Canada, east to New York

 cording to Dr. Horn it occurs over the entire L nited States.
