124 Mr. F. P. Dodd’s Notes upon some remarkable 
DIPTERA. 
No. 11.—In the crevices of the leaf nests of our interest- 
ing green ant, Beophylla virescens, Fabr., a pretty jumping 
spider takes shelter and breeds. Generally it selects the 
nests which are partly abandoned. I was carding some of 
these spiders, but one 2 being rather bulky, seemingly with 
eggs, I kept her in a glass-bottomed box to deposit them. 
One morning I found the spider dead, with abdomen 
strangely small and shrunken, and, instead of a mass of 
eggs, I noticed a peculiar dark object in a thin web the 
spider had spun. Later in the day the object became 
much lighter and I made it out to be a short thick pupa of 
some kind, not unlike that of a butterfly. Finally in about 
twelve days’ time the pupa produced the dipteron now 
shown. The exact dates, and box carefully preserved with 
pupal shell in the web, were lost in the storm already 
alluded to, owing to the destruction of the house I lived in, 
when various entomological specimens of interest were 
destroyed. 
[No. 11 is borne by an Attid spider kindly identified by 
my friend Dr. G. W. Peckham, of Milwaukee, as Cosmophasis 
biteniata, Keys. Dr. Peckham informs me that the 7 = 
Sobara biteniata, and the 2 = Seleaphora rubra, in Koch and 
Keyserling’s “ Arachn. Austral.” p. 1865, and p. 1374. 
The specimen, which is dated Nov. 15, 1902, has a 
shrivelled abdomen, and bears the word “ Dipteron,” so 
it is certainly the host of the Cyrtid fly, Ogcodes doddi, 
Wandolleck, sent with it. The Ogcodes bears the locality 
and date, Nov. 20, 1902. (See Appendix, p. 131.) 
No. 11 is also borne by two more spiders of the same 
species, dated Nov. 11, 1902.]
