jSo. 4.] GYPSY MOTH — APPENDIX. 407 



the veius and nuinerous dots darker brown. Legs pale yellow, 

 remotely dotted with brown. Beneath pale greenish, finely punc- 

 tate, highly polished, the pleura3 witli a row of fine black dots, 

 and an extra dot outwardly ; connexivum acute, the intersegmental 

 sutures indented and marked with a black dot. Tergum black, 

 the sutures, exteriorly, with a double black spot. Length to end 

 of abdomen, 9 to 10 mm. Width of pronotum, 5^ to 6 mm. A 

 pair of these insects taken in Massachusetts have been kindly 

 given to me by Mr. A. H. Kirkland. Other specimens have been 

 sent to me for examination from Rhode Island, Pennsylvania and 

 the District of Columbia. I have found it once, July 4, in a 

 sandy pine woods district in southern Maryland. Only a few 

 specimens have thus far been reported. It seems to be of rather 

 uncommon occurrence." 



A female of this species, confined in a small breeding 

 cage with larvte of Porthetria dispar (L.) and a number of 

 oak leaves, deposited a cluster of thirteen eggs upon the 

 under side of a leaf, June 21, 1896. The eggs were placed 

 in a single layer. Very unfortunately they proved unfer- 

 tile, so that I was disappointed in my anticipation of beino- 

 able to carry the species through its early stages. The ego- 

 (Plate 2, Fig. 11) may be described as follows : — 



Color, pearly white. Length, 1 mm. ; width, .8 mm. 

 Form, nearly cylindrical, the upper and lower ends being 

 abruptly flattened. Around the cap at the upper end of 

 the egg is a row of delicate, elongated, club-shaped spines. 

 The surface of the egg is covered with small single blunt 

 spines, between which are numerous similar spines of 

 microscopic dimensions. 



During the past summer I have been able to establish 

 the fact that this species is predaceous upon the larvoe of 

 the gypsy moth, thus making an addition to the list of the 

 natural enemies of this insect. As an enemy of the gypsy 

 moth it is of only minor importance, and from the slender 

 structure of the beak I am led to believe that the insect 

 is more of a plant feeder than an insect destroyer.
