The following: species were bred from the ])n]»a' <jf the Tiy psy moth : Thnouin milan- 

 ocephala, Br.; I'impla pedalis, Cress.; and an undeseribed species of Mvrapoiux, the 

 last kindly determined forme by L.O.Howard. Besides the.se. several .species of 

 Diptera were bred, but they have not yet been determined. Podisust spinonus, Dall., 

 black ants, and spiders were found in considerable numbers destroying the larv», 

 and no less than ten different species of birds were observed feeding on the cater- 

 jdllars. 



Insect tnip {\f]K 11«!-11.S). — A r('}»oit on a test of the Monitor Moth 

 and Insect Trap. 



These traps are jil.i^s jars with a tin arrangement on top, with holes around the 

 side, near the to]), through wliich the inse»-ts liiul their way to the inside of the Jar 

 ■which is jiartly tilled with an odorous liquid strongly attnictive to insects. The 

 outside of the glass jar has llowers i)ainted upon it with luminons jiaint.

 in the same place and near tlie others. et> that they woiilil have an equal chance with 

 them. The comparison between the ))ainted an<l nnpainted traps sliowc<l that the

 soake«l in the liquid in the traj>s, but they were «!eternuned a.s accurately as pos.sible

 butterliies and sphinx moths, and only one tent cateri>ilhir motli, wliieh was 

 undoubtedly an accidental capture. * * 



,\s tile majority of the injurious insects taken in these trajis lly in the night only,

 use the traps to leave them out only duringthe night, taking them in or ha\ing them 

 closed during the day, so that no insect can get into them. If this is done I think 

 they will prove v<>ry n>ielul.
