I'HE CANADIAN ENTOMOLOGIST. 35 



The moths continue to appear from the ist of August to the close of 

 the month. 



At least three kinds of parasites molest the species ; — • 



1. Pimpla pterelis, Say, which, in August, issues in its perfect state 

 from the chrysalis of the moth. (See 22nd Ann. Rep., Ent. Soc. of Out., 

 p. 18). This species was identified for me by Mr. Harrington. 



2. An insect which, in its larval condition, leaves the chrysalis of the 

 moth about the loth of July, The larva is nearly four lines in length, 

 and is white with a tinge of pink. It spins a white cocoon within the 

 gall. I have two or three of the cocoons, and hope to obtain the perfect 

 insects in due course. 



3. A Bracon. — The larvse of this, numbering from four to ten in a 

 batch, consume the remains of their host at the end of July, and then 

 spin their light drab cocoons in a cluster at the bottom of the gall. The 

 flies appear about the loth of April. 



The perfect insect has the head and thorax black. The abdomen, 

 which is somewhat spindle-shaped, and is attenuated at the junction with 

 the thorax, is honey-yellow, with a brown patch on the upper part of each 

 segment — in some instances the upper part of each segment is entirely 

 suffused with brown. The mouth organs are honey-yellow, and the legs, 

 with the exception of the tarsi of the hindmost pair, which are light brown, 

 are of the same colour. The ovipositor of the female is longer than the 

 abdomen. Its sheath is blunt, hairy and black at the tip, and does not 

 divide in drying. 



I cannot learn that this insect has hitherto been described or named. 

 I would therefore suggest for it the appellation Bracon furtiviis. 



NOTES ON THE LIFE-HISTORY OF AGALLIA SANGUINO- 



LENTA, Prov.* 



BY HERBERT OSBORN AND H. A. GOSSARD, AMES, IOWA. 



This leaf-hopper is considered a clover pest, but is also known to 

 feed on btets, rutabagas, cabbages and blue grass. It is active even in 

 midwinter on sunshiny days. The eggs are thrust beneath the epidermis 

 of the food-plant, and the first brood of larvge appears from the middle of 

 May until July ist. The earliest individuals of the brood are nearly 

 mature by the first of July and are supposed to begin egg-laying a little 

 later. Larvte can be found in all stages of growth from this time until 

 the advent of winter, but most of the individuals are believed to be 

 included in two broods.
