brood. It is probable that the line should 

 be drawn from Tama Co. northward so as 

 to include Mitchell Co. on the north line of 

 the State. 



Our informant reports that they were in 

 Butler Co. " eight or nine years ago " — 

 which may have been intended for the 

 year 1871. 



A correspondent in Mitchell Co. speaks 

 of the year 1855 as '"Locust Year", — and 

 this may refer to 1854, which is the year of 

 the brood of 187 1. 



On the other hand, a correspondent at 

 Waterloo, in Black Hawk Co., says : " I 

 would say from the most reliable informa- 

 tion obtainable, they have not appeared 

 here in twenty-five years, in numbers suf- 

 ficient to attract attention." Another in 

 Howard Co. says: "I have heard nothing 

 of the Seventeen Year Locust since I came 

 here in 1858." The testimony from Win- 

 neshiek Co. is not clear ; my correspond- 

 ent knew of no "locust year" whatever. 



A correspondent in Fayette Co. answers 

 as follows : "(i) Now here. (3) Fourteen 

 years ago. (4) The only locusts that have 

 been here are those above mentioned." 

 This would make the date 1S64, which cer- 

 tainly is somewhat doubtful. 



I am inclined to think that in the last 

 cases, as in that of the brood of 1878, we 

 may have to make corrections, and thus 

 carry the western boundary line from Tama 

 Co. through Bruner, Floyd and Mitchell, 

 as I have indicated on Map I by a dotted 

 blue line. That this area does not extend 

 much if any west of this line is quite cer- 

 tain ; the testimony upon this point is quite 

 conclusive. 



Cave Fauna in Jamaica. — During the 

 spring of 1877, while in the island of Ja- 

 maica I examined many caverns, but found 

 no blind, true cave animals. Insects were 

 not however wanting, although they were 

 all twilight-loving forms found in dark 

 places above ground. In the Jamaican 

 caves there occurred very abundantly a 

 large cricket (?) with well developed eyes, 

 but aborted wings and antenna six inches 

 long. Preying upon the cricket there was 

 also found a Fhrynus {F. reniforinis Fab. ?) 



with fore legs as long as the antennae of its 

 prey. Upon accumulations of bats' dung 

 there lived multitudes of small flies, and 

 upon the bats themselves besides large ticks, 

 mallophagous parasites ( Trichodectes), long- 

 legged, active and wingless spider-flies 

 iNycteribia) and a winged parasitic fly {Stre- 

 bla vespertilioiiis f). A Mycetophilid fly 

 is found upon the stalactites, where its ver- 

 miform larva may also be seen suspended 

 by ropes of slime. The outer portions of 

 the caves are of course resorted to by many 

 myriapods, cockroaches, etc. A curious 

 Hymenopteron, Evania lavigata Oliv. was 

 found parasitic on a large cockroach [Be-

ENTOMOLOGY IN AMERICA IN 1879.

To the study of the Tortricidse — a family, 

 which has received scarcely any attention 

 in this country since the death of Mr. C. 

 T. Robinson, Prof. C. H. Fernald, of 

 Orono, Me., has been devoting special and 

 earnest attention. He has been able to 

 examine nearly all the material contained 

 in the principal collections in this country, 

 and during the past winter has visited the 

 larger collections in Europe for their study 

 and a comparison with our forms. In 

 England, the Tortricidce in the following 

 collections were critically examined by 

 him : those of the British Museum, of 

 H. T. Stainton, R. McLachlan, C. J. Bar- 

 rett and Lord Walsingham ; and on the 

 continent, the collections in Brussells, 

 Berlin, Munich, Naples, of Prof. Zeller in 

 Stettin, Dr. O. Staudinger, MM. Deyrolle 

 and Ragenot and the Jardin des Plants in 

 Paris. The above amount of preliminary 

 work should certainly enable Prof. Fernald, 

 as is his hope, to present us with a re- 

 arrangement of this extensive family quite 

 in advance of any heretofore proposed. 

 Prof. Fernald has prepared a synonymical 

 list of our North American species, which 

 is nearly ready for publication. 



The work of Mr. V. T. Chambers on the 

 Tineidae of the United States, has been 

 vigorously prosecuted, as may be seen in
