The antennae and legs are dark brown, but the hair on the femora 

 and tibiae is yellowish white. 



Parasites. 



Numerous parasites were discovered last summer preying upon the 

 eggs and larvae of the gypsy moth. The following species, deter- 

 mined by Prof. Herbert Osborn, were found destroying the eggs: 

 Tromhidium bulbipes Vack. ; Nothrus sp. near ovivorus Pack. "This 

 species differs from that described by Dr. Packard in having but two 

 capitate appendages on the cephalothorax." Phloeothrips sp. Prof. 

 Osborn says of this last species: "These cannot be identified posi- 

 tively, though they may be the larvae and pupa of P. mali. They 

 agree well with Riley's brief description of his Thrips phUloxerae^ 

 but these are undoubtedly Phloeothrips.'' 



The following species were bred from the pupae of the gypsy moth : 

 Theronia melanocephala Br. ; Pinipla pedalis Cress. ; and an undes- 

 cribed species of Merajoorus, the last kindly determined for me by 

 Mr. L. O. Howard. Besides these, several species of Diptera were 

 bred, but they have not yet been determined. Podisus spinosus Dall., 

 black ants and spiders were found in cousideiable numbers destroying 

 the larvae, and no less than ten different species of birds were 

 observed feeding on the caterpillars. 



BARNARD'S INSECT TRAP. 



Early in April, 1891, Mr. W. C. Barnard, of Worcester, Mass., 

 sent six of his " Monitor Moth and Insect Traps " for trial here at 

 the Station. These were prepared according to directions, and hung 

 in trees in the orchard and gardens. 



These traps are glass jars, with a tin arrangement on top with 

 holes around the side, near the top. through which the insects find 

 their way to the inside of the jar which is partly filled with an odor- 

 ous liquid strongly attractive to insects. The outside of the glass 

 jar has flowers painted upon it with luminous paint.
