with a distinct and permanent species, the whole of the examples captured 

 agreeing exactly with each other. It differs from N. petrosa Walk., N. 

 geomet7-ica Gr., and N. Geddesii Newm., in the shape and position of the 

 bands on primaries, while in all the specimens examined there is on the 

 secondaries an entire absence of white marks. 



I have dedicated this interesting insect to Dr. Alfred R. C. Selwyn, 

 LL. D., F. R. S., F. R. S. C, the distinguished Director of the Geol. and 

 N. Hist. Survey of Canada, whom I have known for many years, both in 

 Australia and America, as a close and careful student, and who has already 

 taken important steps which cannot fail to promote a love for Entomology 

 throughout the Dominion, and to produce the most valuable scientific 

 results.* 



A LIST OF COLEOPTERA COLLECTED IN LOUISIANA, ON 

 OR SOUTH OF PARALLEL 30°. 



BY C. H. T. TOWNSEND, CONSTANTINE, MICH. 



The following species were collected, from 29th March to 21st June, 

 1884, along the thirtieth parallel in two neighborhoods, New Orleans and 

 environs, and a district on Bayou la Fourche extending from a litde above 

 Napoleonville a few miles south along the bayou. The latter is in 

 Assumption Parish, and at the time of my visit was partially overflowed 

 from the great crevasse of March, 1884. Though many of the species 

 here given are well known to occur in the South Louisiana fauna, I give 

 them all just as I collected them, with the view of noting their relative 

 abundance or rarity, dates of occurrence, localities, etc., all of which 

 together may contribute to make our knowledge of the fauna more com- 

 plete. But it must be remembered that this is merely a record of how the 

 species occurred to me during my stay, in which I collected only a small 

 part of what might have been taken, could I have given my entire atten- 

 tion thereto. Nearly all those of the N. O. neighborhood were taken 

 between the city and Lake Pontchartrain. 



Some observations and notes on a number of the species in this list 

 have been published in Psyche {" Notes on Some Coleoptera Taken in 



* The exact locality and date of capture of this Arctian are thus given by Prof. 

 Macoun : " In open grassy woods along an old road between the Hudson Bay Store 

 and the C. P. R. track, three miles east of Red Rock Station, and one mile west of 

 Nipigon Bridge, June 26th, 1884."
