to effect a radical cure. Were the evil only ameliorated it might save thousands of 

 dollars and an immense amount of labor, which is worse than wasted by its disheart- 

 ening nature. * * * 



They appear to go in colonies, eating one man's crop while his neighbor's across 

 the fence is not injured. 



We find that rapid cultivation, large "gangs" of poultry, and numerous birds 

 keep them in check ; but they are becoming too numerous in spite of all we can do.

Note. — This insect of economic importance has existed for many 

 years in the United States without being, so far as I know, mentioned 

 specifically b} r any writer. It is a species of the gryllid genus Anu- 

 rogryllus, which 1 have determined as A. antillarum Sauss. When 

 mature it is readily separable from its ally, A. muticus, by being- 

 apterous and having the elytra more abbreviated. Specimens of what 

 I take to be the young have very small wing pads, but they are rarely 

 discernible in the adult. The National Museum contains specimens 

 from Florida, Alabama, South Carolina, Louisiana, and Virginia, 

 where it is injurious to various garden crops, strawberries, peas, 

 sweet and Irish potatoes, tobacco, and cotton. 



This species probably occurs not uncommonly in collections, but has 

 never been recorded from the United States. Mr. Rehn tells me it is 

 present in the collection of the Academy of Natural Science of Phila- 

 delphia as Miogryllus saussurei; but members of that genus have 

 fully developed ovipositors, while Anurogryllus is peculiar in having 

 that organ aborted. — A. N. Caudeul. 



IDENTITY OF A TINGITID FOUND ON CHRYSANTHEMUM. 



In Bulletin No. 10 new series (page 99), under the head of Extracts 

 from Correspondence, a short note was published in regard to infesta 

 tion of chrysanthemum leaves by a little tingitid bug received in 

 June, 1897, from Alabama, the species having been identified at that 

 time as Corythuca irrorata Riley. Dr. E. P. Felt has recently brought 

 up the subject of the specific identity of this chrysanthemum pest, and 

 Mr. Otto Heidemann, of this ofiice, has furnished the following notes, 

 which will be of value to the systematic worker. 



Under date of June 11, 1903, Dr. Felt sent specimens of the same 

 species, stating that it is seriously injuring chrysanthemum for the 

 past year or two at Coeymans, N. Y. According to Mr. Heidemann 

 the insect in both cases is Corythuca marmorata Uhl., described in 

 Proceedings of the Boston Society of Natural History (Vol. XIX, 

 p. 415, 1878), there being nearly perfect agreement of the specimens 

 with the description. The type of this species is in the Harris collec- 

 tion now in the Boston Society of Natural History museum, No. 61, 

 labeled in the handwriting of Uhler as C mcmnorata. 



Corythuca irrorata is a MS. name of the late Prof. C. V. Riley. 

 It has therefore never been described, and as it is exactly like Uhler's 

 marmorata, would be a synonym in any ease.
