which occur also iu North America. By far the greater portion of these 

 are, however, species of general distribution occurring in almost every 

 l)artof the globe. Eliminating these, the following true American spe- 

 cies are common to the faunas of the United States and Chili: Tetracha 

 Carolina, Bidessus affinis, Laccophilus americamis, L. proximus, Gyrinus 

 parens, Tropisternns r/laber, T. lattraUs, Latlirohium dimidiatum, Atce- 

 nius gracilis, Bruchus scufellaris, Megilla maculata, Eriopis connexa. 



Besides this work on Coleoptera, we have a Catalogue of the Chilian 

 Lepidoptera, by Mr, William Bartlett Calvert, published at Santiago de 

 Chile in 188G, and which enumerates 89 species of Diurnals and 366 of 

 Heterocera; and a list of the Chilian Diptera by Dr. R. A. Philippi in 

 the Verb. K. K. Zool. Bot. Ges. in Wien, 1865, which of course is now 

 somewhat antiquated. 



THE LARVA OF THE CLOVER STEM BORER, Languritt Mozardi Latr., 



AS A GALL MAKER. 



On September 5, 1888, while searching for galls on Solidago, which 

 grows abundantly on the bluffs in the vicinity of La Fayette, Ind., 

 we found a well-developed gall on a stock of wild lettuce {Lactuca can- 

 adensis, L.). This gall was opened carefully, and found to contain a 

 pupa, plainly Coleopterous, of a yellowish color, much enlarged ante- 

 riorly but more slender posteriorly. The gall was at once bound up, the 

 pupa having been replaced in its cavity exactly as found, and the whole 

 placed in a glass jar. On September 21, sixteen days after, an adult 

 of L. mozardi made its appearance in the jar, and an examination of 

 the gall revealed the cavity empty, and the avenue therefrom through 

 which the beetle had made its escape. 



Prof. J. H. Comstock states in the report of the Commissioner of 

 Agriculture for the year 

 1879, p. 199, that the insect, 

 as a clover pest, pupates in 

 the lower i^art of the stem 

 in which the larva origi- 

 nated. We have ourself 

 found larvae not distin- 

 guishable from those of this 

 species burrowing in the 

 stems of timothy, where 

 they pass the winter in the 

 larval stage (see Eei)ort 

 Commissioner of Agricult- 

 ure, 1886, p. 574). The question involved seems to be, is the species 

 .evolving to or from a gall maker f—[F. M. Webster. 



THE USE OF OSAGE-ORANGE AS A FOOD FOR SILK-WORMS. 



Some three years ago the chamber of commerce of Lyons, France, es- 

 tablished a silk laboratory, under the direction of Monsieur J. Dusu-
