from those that actually bite. The case reminds one forcibly 

 of the condition found by Captains Patton and Crags among 

 certain forms of Muscidse in India. 1 It may be added thai ;i 

 specimen of Symphoromyia pachyceras (det. Aldrich) in the Na- 

 tional collection, taken by H. S. Barber at Williams, Arizona, 

 bears the label "biting." Recently the same species has been 

 reported as biting by Dr. J. C. Bradley. 2 The specimens iden- 

 tified by the writer as pachyceras in a previous paper, 3 have been 

 placed by Prof. Aldrich in the course of his revisional work under 

 N. I/ irt a Johnson. 



MUSCA LEPR.E LINNE. 



Under the name Musca leprce the following appears on p:igo 

 598 of the tenth edition of the Systema Naturae: 



M. antennis setariis atra nitens, antennis pedibusque albis, oculis rufo 

 inauratis. 



Habitat in Elephantiasi Nigritum Arneri'cse. Rolander. Corpus pedi- 

 culo minus. Abdomen subtus & basi album. Denticulus utrinque ad basin, 

 proboscidis. 



The description is quite unrecognizable. Later Wiedemann 

 described a small fly under the name Chlorops leprce, but expressed 

 doubt as to its identity with the species described by Linnaeus. 4 

 Becker has recently identified the specimen on which Wiedemann 

 based his description as a species of Hippelates. 5 He also ques- 

 tions its identity with the Linnean species, but retains the specific 

 name on the ground that it has been removed to a different 

 genus. 



For medical entomology the identity of the Linnean specio 

 is a question of considerable interest. No taxonomic data appear 

 in the original description that could serve for accurate identi- 

 fication, but the identity of the fly might be established with the 

 aid of the other data by one favorably situated. Linnaeus evi- 

 dently intended to indicate that the larvae of the fly occurred in 

 cases of elephantiasis and is so interpreted by Wiedemaiin.
