Murgantia histrionica, appeai*ed about Wooster and developed in 

 considerable numbers. It was also found both to the north antl 

 the south in numbei*s sufficient to attract attention, but it has not 

 since been observed farther north than fully forty miles south of 

 "Wooster until 1898. when it seemed to be working slowly north- 

 ward again.— F. M. Webster. 



Allorhina as a Fruit Pest. — "With reference to the note on p. 

 43 it may be Avell to state that the Arizona species is A. mutabilts, 

 not A nitida. This A. mutabiUs is a well-known fruit pest in New 

 Mexico and Arizona, as may be seen by reference to Insect Life 

 and the reports of the Association of Economic Entomologists. —

Machilis conjuncta, Folsom.- This is to be added to the fauna 

 of the United States. I found it at Dripping Spring, Organ Moun- 

 tains, New Mexico; it was identiiied for me by Mr. Folsom him- 

 self. The species was originally described from Mexico— T. D. A. 

 Cockerell. 



Professor Gillette's Note on Allorhina Nitida Linn as a 

 Fruit Pest- — I am sorry that Professor Gillette did not notice 

 my article on Allorhnia nitida in Bulletin No. 10, New Series, of 

 the Division of Entomology, published in Januai-y, 1898, pp. 20 26. 

 K he had done so he would have seen that the insect which damages 

 fruit at Phoenix, Ariz., was i^voha\i\\ Allorhina mutabilis and not 

 Allorhina nitida He would further have noticed that damage to 

 fruit bv Allorhina mutabilis has been a matter of record for several 

 years, and, further, that similar damage to fruit by Allorhina ni- 

 tida is also well known. — L. O. Howard. 



Preservation of Larv.e.— Prof. Packard and Mr. C V. Riley 

 both mention various methods of preserving larvae, but I find the 

 following to be the cheapest, simplest and least dangerous of all : 



Drop the larvae as soon as collected into a pint or quart jar of 2 per 

 cent formalin solution. Date the same and let it stand for a week. 

 Remove the larvae, putting several of each species into a 6 or 8 dr. 

 "shell bottle," filling with fresh 2 per cent, formalin Soak all 

 corks in parafin and keep bottles upright. 1 have had especially fine 

 x-esults withlight green Sphingidae and Bombycidae, which have re- 

 mained in perfect condition since July, 1897. 



Live pupae may be injected and placed in the same bottles, making 

 an inexpensive but beautiful collection. 



I have several Sphingidae in the original leaf, covered with 

 ichneumon in all stages of development. 



Some writers advise boiling specimens, but this I have never 

 tried. Should be pleased to hear from others on this subject.
