larval habits of the tiger beetles. 181 



Addenda. 



While tliis paper was passing through the press, a description of the egg 

 of C repanda came to mj attention. It was overlooked because it was 

 inehided in an article entitled " Habits of CAcindela " (Moore). The eo-gg 

 described must, however, have been abnormal. They were about one-half 

 the size of the usual Cicindelid eggs. Only two were found and thege were 

 fastened together by some filaments. The chorion was sculptured and 

 wrinkled, while in all other known eggs it is smooth. I have found that 

 two or three undeveloped eggs are sometimes left in the ovarian tubules 

 when the laying is ended ; it is barely possible that the eggs observed by 

 Moore were the last from an ovarian tubule. This, however, does not 

 explain the sculpture. 



Since this paper was written Bruch has published an account of the eo-o-, 

 larva, pupa, and adult of C. apiata, Dej. (Bouth America). His article is 

 concerned chiefly with pure description, but he expresses the opinion that 

 there are two generations per year. He has, however, no good observations 

 to establish this point. He figures the ovipositor, hole and egg^ as well as 

 the other stages described. 



Dr. Walter Horn has a paper in the press in which he criticises 

 E. Shelford's paper on Collyrls and gives descriptions of the larvas of a 

 species of Ambhjchila and a species of Omus.
