figured the puparium of Chlorisops (Actina) tibialis Meigen, an 

 European species (fig. 17). The larvae were found in the woods in 

 leaf mold. 



Xylomyiinae.

 I have seen larvae. When placed in weak hydrochloric acid effer- 

 vescence takes place as with the true Stratiomyiid?e. My specimens 

 were obtained from under loosened bark.
