PARASITES 



Hymenolepis flavopunctata, Weinland (1858). 

 See Tcenia flavopunctata, Weinland, (1858). — 

 Hymenolepis nana, Leuckart, (1863). See Tcenia 

 nana, von Siebold (1853). — Hypodectes columbae, 

 Megnin. See Falciger rostratus, Bucholz. — Hypo- 

 derma bonassi, Brauer. A grub recorded as being 

 taken from the back of a buffalo in Colorado. — 

 Hypoderma bovis, De Geer (Latreille, 1825). 

 Syn., CEstrus bovis (1776), Fabricius, Herbst, 

 Fischer, Clark, Latreille, Leach, Fallen, Macquart, 

 Westwood, Sells, Saxisen, Walker ; CEstrus kominis, 

 Gmelin (1788); the Ox- hypoderma, Grub-in-the- 

 back, Warble-fly, Bot-fly of Cattle. A cosmopolitan 

 species, the adult fly having a life of about eight days, 

 occurring during July and August, the larvae living 

 from ten to eleven months in the skin of the cattle 

 and of man. These parasites cause great damage 

 to hides, and the effect on the carcass is serious, pro- 

 ducing what is known as ' ' licked beef " or " butcher's 

 jelly." Squeezing out the maggot is a sure method 

 of getting rid of it, or the warble may be smeared 

 with a thick grease that will choke up its breathing 

 pores. — Hypoderma diana, Brauer (1858). Syn., 

 CEstrus hominis, Volkel. The larva? reported by 

 Joseph Borthen, Volkel, etc., as parasites of the skin 

 in man. — Hypoderma equi, Joly (1849). Syn., 

 Hypoderma silenus, Brauer ; Hypoderma loisetti, Joly 

 (1846) ; CEstrus cuticole, Loiset ; CEdemagena equi, 

 Loiset (1844). The larvae are found in the skin of the 

 horse and ass throughout Europe and S. America. — 

 Hypoderma lineata (Villers), Low (1863). Syn., 

 CEstrus lineatus, Villers (1789) ; CEstrus hcemorrhoid- 

 alis, var. ji, Clark (1797) ; CEstrus bovis, var. (3 %<er- 

 nalis, Clark ; QLstrus lineatus, Olivier (1811); CEstrus 

 ericetorum, Leach(l8ll); Hypoderma lineatum, Brauer 

 (1858); the Heel-fly of Texas ; Grub-in-the-back ; Ox- 

 warble. These grubs cause effusion of serum in the 

 connective tissue, giving an appearance in cattle and 

 sheep called the "lick" by ranchmen. It is stated 

 that the only adult warble- flies found in the United 

 States belong to this species, which appears to be cos- 

 mopolitan. — Hypoderma loiseti, Joly. See Hypo-
