determine one specimen as a male of Sarcophaga hunten 

 Hough. This species happens to be structurally distinct, and, 

 therefore, quite easily determinable. There are, however, 

 at least three species involved in the problem, and in all 

 probability more than three. 



Mr. Knab said that the Sarcophagidse illustrate very well 

 how backward we are in America in some branches of Dip- 

 terology. In Europe it has long been known that certain 

 species of Sarcophagidse are parasitic on other insects; the' 

 facts having been established beyond all question, by compe- 

 tent observers. Kunkel d'Herculais, in his studies on in- 

 jurious locusts (Stauronotus maroccanus) in Algeria, made 

 useful investigations and found that certain species of Sarco- 

 phagidse are important parasites of the locusts. The females 

 of these forms have a modified ovipositor and pierce the host 

 to introduce their larva?, just as is the case with certain Tachi- 

 nidae. Lahille, in the Argentine Republic, has shown that 

 certain Sarcophagidge are parasitic there. Villeneuve has es- 

 tablished genera on certain parasitic species. In this country 

 Chittenden has bred a sarcophagid from a live beetle. A 

 scarophagid has also been bred repeatedly in this country 

 from the box-turtle, and this observation has been made so 

 often that the insect involved must be looked upon as a true 

 parasite of the turtle. 



Mr. Caudell presented the followingnotes on Orchelimum 

 pulchellum : 



On October 2, 1912, at Rosslyn, Virginia, I found near the 

 river a bunch of Hibiscus militaris Can., which has very soft 

 wood with a corky pith. The stems were literally filled with 

 the eggs of what I am quite sure is 1 the above species, as many 

 of both sexes were found on the bush, though none of the 

 females were found in the act of egg-laying; the time of ovi- 

 position, however, was not past, as I found the females still 

 with eggs. It may have been another species that laid the 

 eggs, but it was more likely the above species. Eggs taken 

 from the abdomen of captured females were very like those 

 taken from the stems. It seems, so far as I can make out 

 from the eggs as placed in the stems studied, that from two to
