IOO NATURAL HISTORY BULLETIN. 



the aid of such entomologists as Dr. Geo. H. Horn and Mr. 

 E. A. Schwarz, to both of whom his best thanks are due. 

 By the permission of Dr. L. O. Howard, Honorary Curator 

 of the Department of Insects, the names of the species col- 

 lected by Mr. Schwarz and Prof. Townsend and now preserv- 

 ed in the United States National Museum, have been added to 

 the records and will be found in the proper places. When no 

 credit is given, the writer is to be understood as the collector. 

 Dates are indicated by the months only; however those for 

 June include the period between the twenty-first and the 

 thirtieth, while those for July run from the first to the twen- 

 tieth. Where no definite locality is specified, Brownsville is 

 to be understood in every instance. For the benefit of future 

 writers, in whose minds doubts may arise as to the possibility 

 of any of the records referring to specimens actually captured 

 on United States soil, it may be well to state that no systemat- 

 ic collecting was done on the other side. The Mexican speci- 

 mens obtained were less than a score in number, incidentally 

 gathered while looking over a cotton field near Matamoras, 

 and these represented only species common on the north bank 

 of the Rio Grande. 



CICINDELID^E. 



Tetracha Carolina Linn. A number of specimens were 

 taken in July, under pieces of wood along the bank of a resaca 

 in Fort Brown reservation. The species extends quite across 

 the continent in the south, being recorded from both coasts 

 of Mexico; Florida, Alabama, Mississippi, Louisiana, Texas 

 (Columbus, San Antonio, Laredo, El Paso), New Mexico 

 (Mesilla Valley), Arizona (Tucson). California (Fort Yuma) 

 and Baja California to San Jose del Cabo. According to 

 Schaupp many varieties are known from the West Indies and 

 South America. 



Cicindela rectilatera Chaud. Only tolerably common 

 in the immediate vicinity of Brownsville in June and July, but 

 much more abundant at various places along the stage route,
