SUBFAMILY III. PELECINELLIN^E. 



This subfamily is represented by a single genus, Pelecinella 

 Westwood, readily recognized by the characters given in my table 

 of the subfamilies. See also my paper entitled " On the genus 

 Pelecinella Westwood, and its position among the Chalcididae." 

 Proc. Wash. Ent. Soc., vol. iii, pp. 230-233. 



SUBFAMILY IV. COLOTRECHNIN^E. 



This is likewise based upon a single genus, Colotrcchnus 

 Thomson. It is unknown to me in nature, but evidently from 

 Thomson's description belongs in this family. 



Apropos to Mr. Ashmead's paper, Mr. Marlatt spoke of the 

 danger of using published descriptions only as bases for synoptic 

 work on account of the frequent omission of important characters 

 in published descriptions. 



Mr. Howard made some remarks on the discovery of Eu- 

 proctis chrysorrhcea in the vicinity of Boston, which were sup 

 plemented in discussion by Mr. Marlatt, who had just returned 

 from Boston, and was able to give details as to the work which 

 had been done against the insect, and as to the measures adopted 

 by the State legislature. The paper was further discussed by 

 Messrs. Schwarz and Matthis,
