the capture of this species by the late Hugo Soltau is recorded " on the 

 sandy banks of a small stream near Covington." The Bogue Falaya 

 seemed to be the stream intended, though it is of considerable size, 

 and steamboats from New Orleans cross Lake Ponchartrain and ascend 

 it twice a week. Mr. Coverdale first tried the left bank, but was 

 turned back by barbed-wire fences and trespass signs and finally tried 

 the right bank. The banks at this point are mostly steep, composed 

 of pure white sand, and about every half mile there is a sandbar below 

 the banks. The chief growth on the banks is birch, willow, cypress, 

 sweet gum, tupelo, magnolia, sweet bay, laurel, pine, pecan, ash and 

 various smaller bushes, and in places passage through the tangled vines 

 and shrubs becomes almost impossible. At last, after three hours' 

 search up the stream, he found a sandbar white as the driven snow, 

 on which they were running everywhere, sometimes two or three being 

 caught in the net at one sweep. They are hard to see, the white-haired 

 ventral surface and white side markings making little contrast with the 

 white sand. About two or three o'clock in the heat of the day, C. 

 Wapleri gets in the shade under little bushes. 



The specimens collected vary in size and in the extent of the white 

 markings but not sufficiently to suggest any modification of the pub- 

 lished descriptions. 



Cicindela abdominalis. 



This species occurs plentifully on the banks of the Bogue Falaya 

 River above the water's edge and in the shade of the trees and bushes. 



The following species, though not taken by Mr. Coverdale, have 

 been reported from Louisiana, viz : Pilatei, ohsoleta, ciirsitans, severa, 



haniafa and paiiipliila.

NEW ORTHORRHAPHOUS DIPTERA FROM 

 MEXICO AND TEXAS. 



By D. W. Coquillett. 



In the early part of the present year arrangements were made by 

 Dr. L. O. Howard for identifying a large series of Diptera collected 

 in Mexico and the southwestern portion of this country by Mr. C. H. 

 T. Townsend, and the task of identifying this rich material was as- 

 signed to the writer. A comparatively small number of the species 

 proved to be new to science, and as manuscript names of these will
