work during the summer. * * * Exposure jars were placed from one to ten 
miles apart over the intervening sections, collected, and returned to Uval— 
de (Tex.) for breeding out the materials and making records of materials 
collected in the jars. A total of 835 jars were exposed and 795 were re— 
turned, the difference being accounted for by jars being destroyed or 
stolen at settings, Practically every jar received at Uvalde produced 
returns." The following totals "give a fair idea as to the general dis— 
tribution of the flies bred out, the three larval parasites, and the three 
families of predacious beetles: number of jars exposed, 855; total number 
of flies emerged, 56,214; total Brachymeria emerged, 677; total Xyalosema 
emerged, 861; total Alysia ridibunda emerged, 511; total Mormoniella 
emerged, 5,090; predacious beetle jars, 456. * * * A few of several other 
species of Diptera have been bred and recorded. It is worthy of note that 
approximately 91 per cent of all flies bred from the jars were sarcopha— 
gids of several species." 
Mr. Parman also states: "Brachymeria fonscolombei Dufour is in— 
dicated to be rather generally distributed in scattered infestations east 
of the Rio Grande Vailey and one small infestation was had near Safford, 
Ariz. This parasite has been found as far east as Waller, Tex., and as 
far south as Tampico, Mex., this season. Xyalosema sp. has been indicated 
to be rather generally distributed west of the Pecos Valley with a few 
scattered infestations at Uvalde and south to San Louis Potosi, Mex. 
Alysia ridibunda Say has been indicated to be present in a small area at 
Safford, Ariz., Deming, N. Mex., and Las Cruces, N. Mex. Mormoniella is 
indicated to be rather generally distributed over all sections * * * A 
very few Spalangia sp. have been bred from a few jars." 
R. A. Roberts, who has had charge of the breeding work and local 
parasite status at Uvalde, Tex., submits results of emergence tests for 
the season:

In connection with life-history studies of mosquitoes at Portland, 
Oreg., H. H. Stage reports: "At Wahkeena Falls, three adult Aedes vexang 
Meig. were taken on October 5 and only one on October 7 in the customary 
ten-minute collection. None have been taken since. Because the last pu- 
pae emerged at that point not later than June 22, these individuals were ~ 
at least 105 and 107 days old. In 1930 the longest-lived individuals of 
this species were taken 112 days after emergence."
