From the great resemblance these insects bear to the Bra- 

 conidse, 1 placed this group in my Guide between Bracon and 

 Agathis, but it is evident from the 6-jointed maxillary palpi 

 that it belongs to that extensive sub-family which may now be 

 termed Alysiidse. The typical species are characterized by a 

 perfect trapezoid cell on the costal margin of the inferior wings, 

 and also by the minuteness of the 3rd joint of the labial palpi. 

 The following are British species, and Mr. F. Walker has 

 several others which he found on grass in meadows at South- 

 gate in the summer, and in the Isle of Wight in September. 

 * Inferior wings with a costal cell. 



3. Z. testaceator Curt. — 4- lines long. Ochraceous, eyes and 



spaces between ocelli black : ovipositor fuscous, stigma 

 yellow; posterior tarsi dirty white. 



End of July, Coomb Wood and Regent's Park. 



4. Z. albiditarsus Curt. Brit. Ent.pt. 415. S- 



Taken in the Regent's Park. J. C. 



** Marginal cell of inferior wings wanting. 

 2. Z. ochraceator Curt. Guide. 



5. Z. Ephippium Cwr/. — 2 lines long. Bright ochre; antennae, 



tips of posterior tibiae and of the tarsi, also the ovipo- 

 sitor brownish: eyes and space round ocelli black: 

 thorax reddish; a spot before, the metathorax and 

 base of the abdomen black, nervures and stigma piceous 

 in the male, lurid in the female. 

 My attention was first called to the remarkable oeconomy 

 of this species by a most accurate observer of nature, Mr. John 

 Bolt of Lyndhurst; the cocoon is attached by a thread to a 

 leaf as represented in the Plate, and the insect is hatched in 

 July : it is generally found on the Hazel, on which I have 

 taken it in Coomb Wood. I was a little surprised to find that 

 one of the cocoons produced Hemiteles areator Panz. 

 7. Z. pectoralis Curt. Guide. 8. Z. fulvifrons Curt. Guide. 



9. Z. thoracicus Curt. — Male 2| lines : black shining, disc of 



thorax reddish, legs pale ochre. 



July 16th Regent's Park. 

 *** Antennae shorter than the body. 

 1. Z, atrator Curt. — If line. Piceous black; antennae beneath 

 at the base ochreous; palpi pale ochre, legs dirty 

 ochre, base of posterior tibiae whitish, ovipositor as 

 long as the antennae, wings hyaline. 

 I took several last September on the windows of Durnford 

 House, Wilts, the seat of the Honourable Mrs. Robinson. 



1 0. Z. longicauda Curt. — Similar to the last, but the ovipositor 



is twice as long, and the central submarginal cell of 

 the upper wings is wanting. 

 The Plant is Sviyrnium Olusatnm (Alexanders).
