302 ENTOMOLOGICAL NEWS. [December, 



to which a primeval character has yet been retained, the termite 

 nests find their greatest development, and by their singular pres- 

 ence construct a picture hardly to be matched elsewhere. Like 

 great excrescences of the trees themselves, chocolate-brown or 

 almost black in color, they occupy positions forty, fifty, or even 

 sixty feet above the eye of the spectator. Individual trees may 

 have as many as three or four of these giant nests resting in their 

 axils, while others occupy low positions on the strangled trunks 

 and cable roots of the foresters overlooking the oceanic waters 

 which here and there find their way into the solitude. The 

 greater number of the habitations were irregularly balloon-shaped, 

 and some of them measured not less than four or five feet, or 

 even more, in greatest diameter. On all the tree-trunks thus 

 adorned long and more or less tortuous tunnels, constructed of 

 the same salivary paper, and measuring perhaps two-thirds of an 

 inch across, could be followed by the eye meandering upward to 

 their terminations in the great nests, to which they form the 

 avenue of approach. Wherever tapped they disclosed the same 

 busy life an army of traveling ants as did the interior of the 

 nest itself.

NOTES ON TYPES OF NORTH AMERICAN GEOMETR1NA 

 IN EUROPEAN COLLECTIONS. I. 



By GEO. D. HULST. 



During the last Summer I was able to make a trip to Europe 

 for the purpose of studying the types of North American Geo- 

 metrina. The types of those described by Mr. Walker are in 

 the British Museum, as are those of Prof. Zeller, and many of 

 those of Mr. Grote. Those of M. Guenee are in the collection 

 of Mr. Charles Oberthiir at Rennes, France. I took with me for 

 comparison specimens of the greater part of all our species as 

 known to us, and these often in several varietal forms. In my 

 study every courtesy was shown me, and every effort was made 

 to help me in my work. From a personal standpoint my visit 

 was made a most delightful one, and while not able to complete 

 the proposed work, I was able to do considerable in clearing up 

 the as yet undetermined species of these authors. I express my 

 very grateful appreciation of the favors shown me by Dr. Butler, 

 Mr. Warren, Mr. Kirby, Mr. Hampton and Mr. Oberthiir.
