ENTOMOLOGICAL NEWS. [Jan., '04 



form. It is of interest to note "that, while the majority of the species live 

 in ponds or still water, the more generalized members of both suborders 

 live in rapids of streams." Pages 276-279 by Dr. Calvert are notes sup- 

 plemental to the two lists of N. Y. Odonata published by himself. At the 

 present time about 125 species of dragonflies are known to occur in New 

 York. 



In Part 2 of this bulletin, on pp. 212 and 213, is a discussion of the ecology 

 of ^schna constricfa, especially with reference to its economic importance 

 in relation to brook trout. — E. B. W.

ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE. 



Melanoplus canonicus. — Scudder describes this species from the 

 "Grand Canyon of the Colorado, Arizona, (L. Bruner)." It ought to 

 be recorded that the specimens, though from Prof. Bruner's collection, 

 were collected by Prof. C. H. T. Townsend, who obtained them (accord- 

 ing to a MS. note of his in my possession) down in the canyon, about 

 3000 104000 feet above sea level. — T. D. A. Cockerell. 



A Third Trionvmus. — In Mrs. Fernald's Catalogue of the Coccidae 

 there are two species of this genus recorded, one American, the other 

 European. I find from an article by Sajo in ^eits. fiir Pfianzenkrank- 

 heiten, 1894, p. 151, that there is a third species, Trionymus hordei 

 {Wesiwoodia hordei, Lindemann), found in Russia and Hungary. As 

 this insect has apparently been overlooked by coccidologists, it is just as 

 well to call attention to it.— T. D. A. Cockerell. 



In the Nov. News, page 297. Mr. Philip Laurent doubts the capture of 

 Danais berenice strigosa by myself at Miami, Florida. It would have 

 been more logical for Mr. Laurent to have seen my specimens before ex- 

 pressing his convictions, as there is no doubt about var. strigosa being 

 found there. I took about ten specimens of Timetes petreus at Miami 

 which were identified for me as eleuchea. I did not discover until the 

 present time that they had been erroneously determined for me as eleu- 

 chea and so published in my list. — Morgan Hebard, Chestnut Hill, 

 Philadelphia. 



I CAN GO Mr. Morgan Hebard and Mr. Ellison A. Smyth one better on 

 the northern distribution of Thanaos naevius. I have in the collection 

 of the Dept. Agriculture, a specimen determined as this species on 

 authority of Dr. Dyar, which was taken by Mr. C S. Brimley. at Raleigh, 

 N. C, on May i8th, 1902. — Franklin Sherman, Jr., Ent. Dept. Agr., 

 Raleigh, N. C.
