of insects. First we walked north along the beach below a moderately 

 high bank where there were fossil shark's teeth and various moUusks. 

 Along this shore we found Cicindela JiirticoUis and many Cicindela 

 marginata. The last mentioned is usually found on mud-flats, but in 

 this instance the beetles were running on the beach close to the edge 

 of the water of the bay. Later we turned south and crossing Fish- 

 ing Creek, followed the beach below the very high and commanding 

 bluffs into which the sea is ever eating its way. The soil is largely 

 a clay, and as it falls onto the beach it mixes with the sand, and the 

 character of the beach is thus materially changed. At high tide the 

 water in most places comes up to the very base of the bluffs, but there 

 are several recessions in the hills in front of which there is a narrow 

 beach. Here we found two other species of Cicindela in considerable 

 numbers, namely rcpanda and pnritana. It was certainly a surprise 

 to find the latter species running on the beach of Chesapeake Bay, 

 when its habitat has been usually given as along the Connecticut 

 River at several places in New Hampshire and Connecticut. It is 

 also reported from " New York," but without definite locality. Mr. 

 Leng has pointed out to me that when Dr. Leconte printed his " Cata- 

 logue of the Geodephagous Coleoptera " in the Annals of the New 

 York Academy of Sciences in 1846, he considered the present puri- 

 tana, as later named by Dr. Horn in 1871, a variety of hlanda. Under 

 var. a he describes it as having the elytra fusco-olivaceous with 

 separate narrow marks, and gives as habitat Connecticut River, 

 Roanoke River and St. Croix River in Wisconsin. The Wisconsin 

 specimens were afterwards separated under the name of macro by 

 Dr. Leconte. The Roanoke River locality has not been recently 

 confirmed, but it must have been at least 150 miles to the south or 

 southwest of the Chesapeake Beach colony of pnritana. 



Cicindela rugifrons has not been very often found about Washing- 

 ton, D. C, and Mr. Henry Ulke says of it in his " List of the Beetles 

 of the District of Columbia," " On the hills near Benning's Station, 

 not rare many years ago, but not found again." Mr. Frederick 

 Knab has since found it on one occasion west of Beltsville, Md., and 

 this past summer in company with Mr. Clarence R. Shoemaker, we 

 found many rugifrons, vulgaris and rcpanda in an old gravel quarry 

 at Hyattsville, Md., which is three and one half miles north of Ben- 

 ning's Station. All of the many specimens of rugifrons that we saw 

 were spotted.
