REPORT OF THE STATE ENTOMOLOGIST I909 1 5 



small dipterous larvae, probably Drosophila ; the contents of the 

 pail were quite moist. August 23 there were a number of small 

 flies and other larvae. There were numerous small flies (Borborids, 

 Limosina sp. and a few Sciaras), some pupae and several Staphy- 

 linids in and about the pail September 11. There were also many 

 Psycho da alternata Say, about the pail September 25. 



The new pail placed in the house August 3 contained young 

 mushrooms the 23d. There were a few small flies on the sur- 

 face. September 11 the contents were saturated, slightly rotted 

 and were frequented by a few small flies. A M u s c a p u p a - 

 r i u m was also found. There were some small mushrooms. 

 September 2y numerous Psychoda alternata Say, were 

 observed in and about the pail. 



Station 18. June 29 there were no signs of flies at this sta- 

 tion. July 8 there was no evidence of maggots being present 

 though the pail was more moist than tho'se at stations 6 and 23. 

 July 17 there was much fungus on the manure though no flies 

 were observed, not even Sciaras. The same was true July 21 

 and 25. August 3 there were a very few small flies on the 

 margin of the pail but no evidence of larvae. August 23 there 

 were a few small flies, probably Limosina and Sciara and sev- 

 eral clusters of larvae, the latter being much less abundant 

 than at stations 6 and 2^3^. September 11 a few small flies and 

 dipterous larvae were seen. The larvae were probably those 

 of Sciara and Limosina. Psychoda alternata was 

 reared from this pail, also a species of Scatopse. September 

 27 Psychoda alternata was rather abundant about the 

 pail. 



The new pail placed in the house August 3 was frequented 

 by only a few small flies on the 23d. There was no evidence 

 of larvae being present. September 11 only a few small flies, 

 mostly Sciara and Limosina were seen. There were a few 

 mushrooms in the pail. September 2"] Psychoda was rather 

 abundant. 



Station 12. June 29 there were no signs of flies and the 

 same was true July 8 though the pail was fully as moist as the 

 others. July 17 conditions were practically the same as at 

 station 18 though with perhaps less life, only a few mites being 

 observed. Fungus was rather abundant on the manure. July 

 21 and 25 no flies were observed. August 3 neither flies nor 

 larvae could be found. August 23 there were a few small flies
