proved to be Cicada pniinosa. Apart from its structural characters it can 

 readily be distinguished, even at quite a distance, by the peculiar song ; this 

 is a prolonged zip . . . accompanied at intervals by a metallic twang-tzvang. 



Mr. E. D. Harris stated that recent correspondence with Mr. H. P. Loding, 

 of Mobile, Ala., had elicited some facts regarding the periodicity of the local 

 Cicindelids that will be of interest, and which Mr. Loding has kindly per- 

 mitted him to communicate to the Society. 



The forms taken by him in southern Alabama are Tetracha Carolina, 

 Cicindela rcpanda, hirticollis, nigrior, unicolor, sexguttata, rufiventris, cumatilis, 

 punctnlata, severa, abdominalis, soulayi, tortuosa, blanda, hamata, togata and 

 gratiosa. The season opens with unicolor early in March, and this form con- 

 tinues until the latter part of May, disappearing to come again in October, 

 late specimens occurring in the last part of December even up to Christmas. 

 It varies in color from a deep blue to bright green, but is always immaculate. 

 Mr. Loding expressly stating that he " has never seen any specimens with 

 the least signs of markings." The closely related form of nigrior appears in 

 the latter part of September and remains till the end of November. It is 

 observed also in the spring. The two forms, unicolor and nigrior are not 

 locally associated. The first specimens of repanda and gratiosa appear 

 towards the end of March and remain till into September, the latter frequenting 

 white sand, " high and dry," all over Mobile Co. Blanda occurs at Oak 

 Grove and Grand Bay, " on wet white sand near creeks," from May to August. 

 Punctnlata appears in May, followed by tortuosa, and later by abdominalis, 

 this last being very common on roads and paths until late in September. 

 Scabiosa has not been observed, though careful search has been made for it. 

 Hamata occurs near the water edge along the bay and gulf shores, through 

 June, July and August. Sauleyi, with its immaculate form, is there in June 

 and July. Rufiventris and cumatilis occur in greatest abundance in Jvily and 

 occasionally belated specimens linger till late in September. Togata occurs 

 at Coden on sandy salt marshes. Hirticollis occurs sparingly with repanda 

 in mid-summer. Sexguttata is not common, Mr. Loding reporting that he 

 has taken but one specimen in five years. Severa, one of the rarer forms, 

 occurs at Coden. " It keeps close to grass, is not shy, and is out more morn- 

 ing and evenings than in the middle of the day." The black form is the 

 more common, the green being only occasionally met with. It is found on 

 sandy salt marshes. Mr. Loding observes that in a series of unicolor taken 

 in the middle of October of this year, all males had " the labrum and at least 

 part of the mandibles white, and all females had both labrum and mandibles 

 black or bluish." 



Mr. William T. Davis exhibited dried specimens of a wild bean (Phaseolus 

 polystachus) and some beans from the same species infested with a small 

 weevil (Apion griseus). 



Mr. Shoemaker exhibited a beautiful hand-painted specimen of the brilliant 

 Australian butterfly, Ornithoptera priamus. 



Mr. Dow recorded the capture of Cicindela oncocisconensis Harris at De 

 Bruce, Sullivan Co., N. Y., at an elevation of 1,700 ft. Mr. Leng mentioned
