276 ENTOMOLOGICAL NEWS [XXXI, '20 



Havana, 111., three males, June 3, 1918; Meredosia, Illinois, 

 four males. May 28, 1917; Oregon, Illinois, two males, June 

 19 and 21, 1917. 



The type and allotype were taken in copula, and the data 

 were lost for them and the other two from Havana several 

 years ago when the catalog containing them went amissing. 

 These specimens were taken by Mr. C. A. Hart, the others 

 were taken by the writer. 



Aspistes analis Kirby. 



This species differs from the foregoing in having the antennae 7-seg- 

 mented in both sexes, the media leaving radius very close to the cross- 

 vein and in being larger, averaging 3.5 mm. in length. 



Localities, Iditarod, Alaska, two specimens, July 3, 191 7; 

 Beaver Mts., Alaska, five specimens, October 14, 191 7 

 (A. H. Twitchell). 



The difference in the antennal structure and in the form of 

 the hypopygium, which is quite marked, would suggest the 

 propriety of the retention of the genus Arthria for this species. 



A Webspinning Sarcophagid, Parasitic upon a Mantis (Dipt., 



Orth.). 



At Wichita, Kansas, in the fall of 1919, a fly which was later identified 

 by Dr. J. M. Aldrich as Sarcophaga setigera Aldrich, was reared from the 

 female of Stagmomantis Carolina lAnn. The mantis was found upon a 

 morning glory and clematis arbor on the afternoon of September 25th. 

 The observer noticed a wound upon the abdomen of the mantis and think- 

 ing it the result of a bird peck, took the mantis into her hand to put it 

 out of its misery. Just as the head was severed from the body, the mag- 

 got crawled from the abdomen of the mantis onto the hand of the ob- 

 server. The inaggot was transferred to a covered glass dish with a morn- 

 ing glory and a clematis leaf in it. Upon the morning glory leaf, the 

 larva wove an irregularly shaped tubular web about 27 mm. long and 7 

 mm. wide. This web was composed of broken strands of white silk 

 making a dense mass, but one transparent enough for the larva to be 

 seen within. After remaining quiescent for three days within this web, 

 the larva pupated at one end of the tube and the adult emerged in four- 

 teen days. 



How or where this form normally spins a web is a question which can- 

 not be answered from this observation. Hazel Elisabeth Branch, 



Ithaca, New York.
