Dec, iQii.] Davis: Notes on Collecting in Georgia. 217 



in copulation with a female Cicindela punctiilata. The pair were 

 promptly collected to avoid chances of error in regard to sex. 



We set a great many trap jars baited with " sugar " mixture in the 

 woods, and as a result captured numerous ants and beetles and a great 

 many specimens of Ceuthophili. The latter have been identified with 

 reasonable certainty as Ceitthophihts lapidicola, Ceuthophilus uhleri 

 and Hadenoccus pufeanus. Among the beetles Carabus limbatus fell 

 into the traps in great numbers. Later, when they were examined, it 

 was found that there were 24 males and 49 females. A similar col- 

 lection of limbatus had been made in June in company with Mr. 

 Ernest Shoemaker, along the Potomac river near Washington, D. C, 

 and contained 22 males and 49 females. A comparison of these two 

 collections showed that the specimens from the mountains of Georgia 

 averaged smaller than those from further north. The length of the 

 elytra was measured with the result that Georgia specimens averaged 

 12.73 itirn., while those from along the Potomac averaged 13.67 mm. 

 There were many specimens with the elytra only 12 mm. in length in 

 the Georgia lot, while there was but one of that length among those 

 from the vicinity of Washington. Again there was none as long 

 as 15 mm. in the Georgia collection, while there were six of that 

 length among those from the Potomac. Carabus has its best and 

 greatest development in northern latitudes. 



We found a pair of Canthon nigncornis rolling a sheep dropping, 

 and a Canthon chalcites in a decaying fungus. Fifty-eight specimens 

 of the larger Canthons were examined, and we might have inspected 

 several hundred, for they were very common. Of this number fifty- 

 seven were chalcites and only one Icevis. Last year Iccvis was in 

 greater proportion. In one spring there were four Canthon balls that 

 had been recently lost to their owners by rolling down hill into the 

 water. 



Near the last of the month of July, while waiting for a train at 

 Cornelia, Ga., we rambled in a small woods and along a path 

 where there were some Cicindela ritfiventris. Here we also found 

 the excrement of some small mammal, probably a skunk or an opos- 

 sum, containing the wing covers and hard parts of a number of 

 insects. Li this excrement there were a number of Canthon viridis. 

 This was the first time we had found it feeding, for it usually occurs 

 on low vegetation or under loose material on the eround.
