bifasciata) and Mycetophila punctata and hlanda (Engel 1. c), from 

 dead Onjctes fiasicormis, pupa of Sphinx atropos, decaying Lepidop- 

 terous larvæ among others Ocneria dispar, pupa of Vaiiessa antiopa, 

 frojn bee-hives (here it is often common and has, therefore, been 

 miscredited as the cause of foul brood, thoiigh evidently only. present 

 as a scavenger), from nests of Vespa germanica, larva of Nematus 

 salicis, and from dead snails; Schnabl (see Mik. Wien. Ent. Zeitg. II, 

 1883, 46) mentions the larva vomitted numerously by a patient who 

 had lived on somewhat piitrid potatoes, but as the author, as seen 

 below, had earlier mistaken a Muscid larva for that of rufipes, the 

 observation is perhaps not correct; the larva of this species is also 

 mentioned by Chapellier (Feuille des jeun. Naturalistes, 43, 1913, 55) 

 as living in bodies of Canary birds prepared with vapours of formaline; 

 A. pulicaria Fall. from cow-dung, from nest of Vespa germanica, and 

 from an Agaricus; A. pusilla Meig. from an Agaricus, from Bomhyx 

 pini, and from under the bark of a pine-tree in excrements and detrite 

 from bark-beetles and remains of an Astynomiis aedilis; A. pygmaea 

 Zett. from a mushroom (Engel 1. c). Malloch 1. c. mentions the follow- 

 ing American species: A. jungicola Coqu. from the fungus Trametes 

 pecki; A. agarici Lintn. on decaying mushrooms; A. scalaris Loew 

 from onions and decaying insects; A. conica Mali. from abdomen of 

 Camponotus pennsylvanicus; A. aletiae Com. from pupa of Aletia; 

 A. atlantica? Brues on rotten Aletia pupa; A. evarthæ Mali. from dead 

 beetles and from fungi; A. setacea Aldr. from cocoon of Cimbex ameri- 

 cana. Still a couple of unidentified species have been noted: A. tiiberi- 

 cola Schin. from truffles and A. bovistae Gimmerth. in a fresh Lyco- 

 perdon. The exotic species A. xanthina Speis. = ferruginea Brunetti 

 (and perhaps = scalaris Loew) (Schmitz, Wien. Ent. Zeitg. XXXV, 

 1916, 228) has been bred from dead insects and from a Lacertid 

 {Calotes versicolor), and this species is interesting as it is said to 

 cause myiasis in man, infesting the intestine and being able to complete 

 its life cycle as an internal human parasite (Austen, Trans. Soc. 

 Trop. Medie, et Hyg. III, 1910, 229). — I have myself bred ruficornis 

 from a pupa found in flood refuse at the border of a pond, and I have 

 seen errata with its pupa found in a similar place, further I have rata 

 bred from a pupa in flood refuse, from larvæ in dead Lepidopterous 

 larvæ, from larvæ in a dead Orgyia antiqua, from larvæ in a dead 

 Prionus coriarius, from pupæ found in the nest of a chaffinch, and 

 from nest of Vespa vulgaris] rufipes I possess bred from decaying 

 seed of lupines, from fungi, from nests of wasps, from bee-hives,
