Larvae of Cephenomyia in a Man's Head. 



I was called to see a case to-daj-, wlio bad just come from Swartbout Cafioii, 30 

 miles from bere, tbe messenger stating tbat bis fatber bad Screw Worms in bis nose and 

 wanted me to get tbem out. I found tbe patient at tbe bome of bis son, in Led. His 

 name is E. P. Fowler; age, Gl ; occupation, a carpenter; native of New York ; raised 

 in Obio. I found bini breatbiug bard, accelerated pulse and temperature, a bloody 

 mucus issuing from tbe nose, tbe passages nearly closed from dried blood and mucus, 

 nose swollen and pain between tbe eyes, as well as reddened looking in tbe moutb, 

 witb tbe back parts of a leaden color and covered witb mucus. I procured warm 

 water, carbolized it, and took forceps and small plugs of cotton and removed tbe dried 

 secretions as fixr as I could, I tben came on to tbe maggots and removed 40 of tbem 

 witb tbe forceps from tbe nose. I used a powder-blower and blew into eacb nostril 

 in diflferent directions an impalpable jiowder of calomel, after wbicb several maggots 

 came away of tbemselves. Iseud you asample of five of tbem in tbis mail. Mr. Wrigbt, 

 my neigbbor, being an entomologist, I gave liim a number of tbe maggots. He re- 

 ports tbem feeding on a bony piece of raw beef, tbey baving refused cooked beef I 

 bope to gain some information of tbe fly, wbetber it is identical witb tbe SbeepGrub, 

 Green Bottle fly, or is it an individual species. Tbe patient bas bad nasal catarrb 

 for many years, and it is probable tbe secretions formed a suitable field for tbe deposit 

 and development of tbe maggot. — [Wesley Tbompson, M. D., San Bernardino, Cal., 

 August", 1889. 



Reply. — Your very interesting letter of August 7 bas just come to baud, and tbe 

 specimens also arrived in good condition. Tbe larvie wbicb you send do not belong 

 to tbe species wbicb is ordinarily known as tbe Screw Worm, but to a different group. 

 Instead of being ]Muscids tbey are CEstrids, and altbougb it is impossible to determine 

 tbe precise species from tbe larva-, the genus is Cephenomyia. Tbe larva) of tbose 

 species of tbis genus of wbicb we know tbe larva?, are found in tbe nasal passages 

 of deer, and witbiu tbe last two mouths we have received from Mrs. Bush, of Sau Jos6, 

 larviB taken from tbe deer which may be tbe same species as the one which you send. 

 Tbe occurrence of this larvse in tbe head of your patient was of course more or less 

 accidental, although not without precedent. I bope tbat Mr. Wrigbt will succeed in 

 rearing tbe fly, although the larvie are evidently not more than half grown, and suc- 

 cess seems doubtful. — [August 15, 1881).]

Fore-win(j8, rather shining saffron witb snow-white markings consisting of two trans-

 fascia at one-fourth tbe wing-length is but slightly angulated, margined with 

 scattered blackish scales, widely on its outer and very indistinctly on its inner 

 side; tbe second fascia at tbe middle of the wing is rather more strongly angu-
