Funicle with 2 long branches Dicladocerus Westwood. 



Funicle with 5 long branches Pentacladia Westwood. 



Tribe II. Hemiptarsenini. 



The single-spurred hind tibise distinguish the tribe ; otherwise it is not distin- 

 guishable from the preceding tribe. 



The genera are not numerous and may be easily recognized by the characters 

 made use of in the following table :

Family LXXII. TRICHOGRAMMID^. 



1846. Eulophidse, Family II. (partim). Walker, List Chalc. Brit. Museum, I., p. 62. 

 1856. Trichogrammatoidse, Family XXIL, Forster, Hym. Stud., II., pp. 20, 26 and 



87. 

 1897. Trichogrammatinse, Underfam., Aurivillius, Entom. Tidsk., 18, p. 250. 



Dr. Arnold Fdrster was the first to recognize this natural family, which is at 

 once distinguished, from all other groups, by the tarsi being 3-jointed, never more 

 nor less. 



It comes nearest to the Family Eulophinas, where Westwood placed his genus 

 Trichogramma in 1840, and apparently forms a connecting link between that family 

 and the next, or the Mymaridse.
