After giving records of numerous 

 other cases he further adds : 



••To Dr. Lesbini, of C6rdoha, are due 

 the better observations upon cases ot 

 myiasis prochiced bv C. macellaria. 

 Tlie first case presented itself in an old 

 foreigner who had an ulcer in his leg 

 filleil with these larvae ; the second case 

 occurreil in C6rdoba, in a boy of seven 

 years, attacked in the left ear ; the third 

 a"nd last case \vas in a girl of sixteen 

 yeai's, also of C6rdoba. atlected in the 

 nasal fossae by the presence of two hiui- 

 dred and fifty larvae : all these patients 

 were saved." 



'•It is pi'obalile that, attracted by the 

 fetid odor of unclean individuals, these 

 flies hover over the mouth or the nose. 



and thus deposit their eggs ; some aflirni 

 that they at times enter the passages for 

 this purpose." 



•■The area of distribution of Conip- 

 somyii! macellaria is very great, and 

 will be, I believe, yet greater with time, 

 since their habits facilitate their trans- 

 portation 1>\' man from one region to 

 another ; hitherto they have been ob- 

 ser\ed in the following countries: Is- 

 lands of America (^fiisca macellaria 

 F.), X. America ( Chrvsovivia tibialis, 

 C. r/icrii/i/iicri. C. cacriilesccns., C. 

 decora C. plaei R.-Desv.), Mexico 

 (Lucilia hoininivorax). Cuba, Colom- 

 bia, Venezuela, Cayenne, Brazil, Peru, 

 C'iiili. Uruguay, Argentine Republic 

 and New' Holland." 



Influknce of color ox insects. — 

 The following extract from the recently 

 published second part of \()I. i of 

 "Timehri." the Journal of the Royal 

 agricultural and commercial .societv 

 of British Guiana, so abl\- edited bv 

 Mr. E. F. im Thurn, may be of interest 

 to our readers. It occurs in an account 

 of a visit to Mount Russell in (iuiana. 

 by the editor (p. 223) : — 



"That afternoon the Indians of the 

 place, seeing our interest in catching 

 butterflies, exhibited various clever 

 ways of entrapping these insects. To 

 catch those of yellow hue, thev picked 

 and laid on the ground the flowers of a 

 yellow Bignonia (/>'. cl/icka) \ antl 

 this proved a most successful plan. 

 Equally successful were they when they 

 laid decaying banana-skins on the 



ground to attract the large l)lue 

 Alorplios ; hut an attempt to attract 

 certain red species by displaying the 

 ripe red fruit of the faroah plant {Bixa 

 orellat/a) was not successful. Then, 

 these methods of enticing the insects 

 w ere completed by inverting a round 

 <)uake (a w ide-mouthed basket of very 

 open wicker-work) over the bait, taking 

 care to raise the quake so that its lower 

 edge was some inches from the ground. 

 The butterflies, attracted by the flowers, 

 made their wav under the raised edge 

 ot the ijuake. and wiien the Indians ap- 

 proached flew, not out under the edge 

 of the cjuake, but upward into the top. 

 where they were captured." — E. C. R..
