THE AMERICAN ENTOMOLOGIST. 



aid of the one great book of Nature, open 

 to all. In respect of scale insects it is often 

 pardonable, because necessary, to name a 

 species from the female scale alone with- 

 out characterizing the male or the newly- 

 hatched larva, but this should only be done 

 where the female scale is quite character- 

 istic. 



We do not hold ourselves responsible 

 for our manuscript name adopted by Mr. 

 Ashmead which, while convenient to use 

 in a cabinet, will probably have to be re- 

 jected upon more careful study or more com- 

 plete knowledge of the sexual characters. 



We announce with extreme regret the 

 death, on the 29th of September, of Jacob 

 Boll, of Dallas, Texas. He died while en- 

 gaged on an exploring expedition for Prof. 

 Cope, in Wilbarge Co., Texas. He was 

 not only one of the best collectors and 

 observers of insects, but proved himself 

 one of the most intelligent and successful 

 collectors in other departments of Natural 

 Sciences. He also published a number of 

 articles on botanical and geological, as well 

 as entomological subjects. We knew him 

 chiefly as an entomologist, and we have 

 rarely, if ever, met with a man who com- 

 bined more effectually keen powers of ob- 

 servation with skill in mounting and pre- 

 serving the most delicate organisms. His 

 aged grandmother and his children have 

 our sincere sympathy in their bereavement. 



Remedy for Cabbage-worms. — Of all 

 the many topical remedies that have been 

 tried for the Imported Cabbage-worm since 

 it first began to spread over the country and 

 to play havoc with our cabbage fields, few, 

 if any, have given entire satisfaction. It 

 is safe to say that the most satisfactory 

 remedy so far discovered is in the use of 

 Pyrethrum. We were the first to apply 

 this in 1879, but did not care to recom- 

 mend it until further experiments had been 

 made. These we have made the present 

 year, and caused to be made by a number 

 of our agents and correspondents. The 

 general experience is most favorable, and 

 we unhesitatingly recommend it for all the 



different worms affecting the leaves of our 

 cabbage plant. 



Pyrethrum for the Screw Worm. — 

 We publish in the current number an arti- 

 cle from Dr. Kilpatrick on the Screw- 

 worm which well illustrates the terrible 

 wounds which this insect is capable of in- 

 flicting, not only on animals in Texas, but 

 on human beings. One of the most im- 

 portant discoveries incidental to the work 

 of the U. S. Entomological Commision 

 which we have made during the year is 

 that Pyrethrum may be successfully em- 

 ployed against this pest also. Prof. J. P. 

 Stelle, one of the agents of the Commis- 

 sion, thus writes from San Marcos, Texas : 



I have just made a discovery that cannot be 

 otherwise than of vast importance to Texas : 

 PjTethrum is a never-failing remedy for the no- 

 torious Screw-worm. The application is made 

 by simply dusting a little of the dry powder over 

 the sore ; the worm being an air-breather, soon 

 takes in the effect and dies. 



Up to this time the remedies for Screw-worm 

 in Texas have been either arsenic or calomel. 

 The former always leaves a serious sore, while 

 the latter often does the same thing, and when 

 applied to )'oung calves always produces saliva- 

 tion. P3'rethrum leaves no unpleasant effects. 



OviPOSITION IN THE TORTRICID/E. 



Prof. C. H. Fernald in his notes on Phox- 

 opteris angulifasciana makes some interest- 

 ing facts as to the oviposition of this 

 moth which is one of those species in 

 which the eggs are deposited singly. He 

 describes the process as follows : 



" She fluttered about on the upper side of the 

 leaf for a little time, then standing over and in a 

 line with the midrib, she deposited an egg on 

 the midrib, about one-third the distance from the 

 end. In some cases only one egg was deposited 

 on a leaf, in others, two ; but in the latter case 

 the second egg was deposited in the same man- 

 ner as the first, but at a third of the distance 

 from the opposite end of the leaf." 



We wish some one could succeed in ob- 

 serving the more common form of oviposi- 

 tion in these moths, viz.^ where the flatten- 

 ed eggs are so regularly and beautifully 

 laid in large, translucent batches or long 

 rows, upon the leaves or branches of plants. 



Exchanges Wanted. — A. W. Latimer, 

 Eufaula, Ala., is desirous of exchanging 

 with collectors in Europe and of the Pa- 

 cific coast.
