Larvae of Cephenomyia in a Man's Head. 



I was called to see a case to-day, who had just come from Swarthout Canon, 30 

 miles from here, the messenger stating that his father had Screw Worms in his nose and 

 wanted me to get them out. I found the patient at the home of his son, in hed. His 

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

 in Ohio. I found him breathing hard, accelerated pulse and temperature, a bloody 

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

 nose swollen and pain between the eyes, as well as reddened looking in the mouth, 

 with the back parts of a leaden color and covered with mucus. I procured warm 

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

 secretions as far as I could. I then came on to the maggots and removed 40 of them 

 with the forceps from the nose. I used a powder-blower and blew into each nostril 

 in different directions an impalpable powder of calomel, after which several maggots 

 came away of themselves. I send you a sample of five of them in this mail. Mr. Wright, 

 my neighbor, being an entomologist, I gave him a number of the maggots. He re- 

 ports them feeding on a bony piece of raw beef, they having refused cooked beef. I 

 hope to gaiu some information of the fly, whether it is identical with the Sheep Grub, 

 Green Bottle fly, or is it an individual species. The patient has had nasal catarrh 

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

 and development of the maggot. — [Wesley Thompson, M. D., San Bernardino, Cal.,

Reply. — Your very interesting letter of August 7 has just come to hand, and the 

 specimens also arrived in good condition. The larvae which you send do not belong 

 to the species which is ordinarily known as the Screw Worm, but to a different group. 

 Instead of being Muscids they are OEstrids, and although it is impossible to determine 

 the precise species from the larvae, the genus is Cephenomyia. The larvae of those 

 species of this genus of which we knpw the larvae, are found in the nasal passages 

 of deer, and within the last two months we have received from Mrs. Bush, of San Jose", 

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

 The occurrence of this larvae in the head of your patient was of course more or less 

 accidental, although not without precedent. I hope that Mr. Wright will succeed in 

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

 cess seems doubtful.— [August 15, 1889.]

Lithocolletis nemoris sp. n. 



Antenna^ white, spotted above with fawn brown. 



Palpi, white. 



Bead, face white, frontal tuft whitish, much mixed with saffron-brown, especially at 

 the sides. 



Tlwrax, saffron. 



Fore-wings, rather shining saffron with snow-white markings consisting of two trans- 

 verse fascia, slightly oblique, and augulated beneath the costal margin, beyond 

 which are one dorsal and two costal streaks; there is no basal streak ; the first 

 fascia at one-fourth the wing-length is but slightly augulated, margined with 

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

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