NOTES FROM CORRESPONDENCE. 
Maggots in poor butter.— Dr. E. G. Love, of New York City, has sent us speci- 
mens of maggots found in poor butter. These maggots seem to belong to the genus 
Drosophila, but can not be determined specifically. 
New Habitats for the Florida Red Scale and White Fly. — We have received 
from Mr. F. W. Mally, Dickinson, Tex., leaves of a lemon tree affected by the Florida 
red scale {Aspidtotus fieus Ashm.) and of the white fly {Aleyrodes citri R. & H. )• 
Neither of these insects has previously been recorded west of Louisiana. The prob- 
abilities are that both were introduced from Florida into Louisiana during the New 
Orleans Cotton Exposition of 1885. The original home of the former insect is the 
West Indies or South America, while that of the latter is not known. 
Northward Range of the Wheel Bug.— In reply to our inquiry in a previous 
number of INSECT Life. Mr. Thomas K. Parker, of Providence, R. L, writes us that 
in past summers he has noticed the wheel bug (Prionidus cristatus) in the vicinity of 
Providence. He has seen both the insects and their eggs upon board fences. 
The Potato Scab-gnat in Missouri.— Dr. R. M. Higgins, of Webster Groves, Mo., 
has sent us specimens of potatoes affected by Mr. Hopkins' new Epidapus scabies, pro- 
ducing a similar form of scab to that described in volume VI of Insect Life (p. 319) 
and in the last volume (p. 117). 
Oklahoma Food of the Harlequin Cabbage-bug. — Dr. J. C. Neal. director of 
the Oklahoma Agricultural Experiment Station, writes us that the alkali mustard 
( Cleomella angustifolia Torr.) is one of the food plants of the harlequin cabbage-bug 
which is slowly spreading over Oklahoma Territory. The Cleomella, according to 
Dr. Neal, grows from choice over thousands of acres of alkali flats and gives an 
early start to the cabbage-bug. 
The Apple Maggot in North Carolina. — In an apple received by the Pomologist 
from Mr. George E. Boggs, of Waynesville. N. C we found larvae of Trypeta pomo- 
nella, the well known apple-maggot fly of the Northern States. We place the fact 
on record, as from our information the locality is new. 
Abundance of Army Worm Moths. — In view of the fact that 1891 has been an 
Army Worm year in Virginia and Maryland, it is interesting to note that Mr. Frank 
M. Jones, of Wilmington. Del., in the course of his collecting at electric lights in that 
city, out of a total of 9,500 specimens found that 8,000 were army worm moths. 
The Sugar-cane Weevil in the Fiji Islands. — Mr. Albert Koebele informs us that 
the Colonial Sugar Company of the Fiji Islands has been trapping the sugar-cane 
weevil ( Sphenophoras obscurus) in large numbers with pieces of split cane. In this 
way no less than eleven and a half millions of the beetles have been collected with 
the practical results that while two years ago 32 per cent of the cane was infested 
the present season only 7 per cent was infested. 
Inoculation against Insect Stings.— Mr. Herbert EL Smith writes as that in 
his experience particular parts of the body may become temporarily inoculated 
against insect stings. He used to catch small wasps in his net with his fingers. 
The fore-finger of the left hand was stung so often that it lost all susceptibility even 
to severe stings, and it remained so for two or three years. It is now, however, as 
susceptible as ever. 
The Ceylonese Spider Parasite. — In our first note on the external parasites of 
spiders, in Insect Life (vol. I p. 12), we mentioned the illustrated article by Mr. 
E. Ernest Green, of Punduloya, Ceylon, in Hardwicke's Science Gossip, for .Inly. 
1888. Only recently Mr. Green has had the kindness to send us specimens of the 
spider and of the parasite itself, and it is interesting to note that the parasite 
proves to belong to the genus Zatypota. to which at least one of our American 
external spider parasites also belongs. The spider itself is a handsome little spe- 
cies with a triangular abdomen, which Dr. Marx tells us belongs to Cambridge's 
genus Chrisso.
