ously marked, the body being dark brown with the an- 

 tennje and legs pale, and the wings iridescent. The highly 

 magnified outlines at figure 72 will convey a good idea 

 of its appearance, a showing the wings folded on the back, 

 6 one of the front wings, c one of the hind wings, d one 

 of the legs, and e one of the antennae. 



I shall leave the proper determination of this insect 

 to those who pay more particular attention to the Chal- 

 tididce. It comes nearest the genus Trichogramma, 

 Westw., and may be provisionally called Trichogramma 

 (?)minuta. It differs from that genus and from all 

 other Chalcididan genera with which I am acquainted, 

 in the antennae being but 5-jointed (scape, plus 4 joints), 

 the scape stout and as long, or longer, than joints 2, 3 

 and 4 together; joints 3 and 4 small and together as 

 long as joint 2; 5 very stout, fusiform and as long 

 as 2, 3 and 4 together. The legs have the trochanters 

 stout and long, the tibia? not quite so long nor so stout 

 as the femora, and with a long tooth; the tarsi 

 are 3-jointed, with the joints of equal length and 

 with the claws and pulvilli subobsolete. The abdo- 

 men is apparently 6-jointed, the basal joint wide, the 2nd 

 narrower, 2-5 increasing in width till 5 is as wide as 1. 

 The ovipositor of ? extends a little beyond the apex, and 

 starts from the anterior edge of the 5th joint." [pp. 157-

The figures accompanying- this description are excellent as 

 far as the general appearance of the species is concerned but of 

 course their details are carelessly drawn, but only in regard to 

 the wing ciliation, thoracic characters and antennal structure, the 

 antennae not showing a ring-joint. The latter point mislead others 

 in regard to the generic position of the species and the consequent 

 uncertainty lead to that confusion whose presence has been already 

 intimated in these pages. The original description was repub- 

 lished in Riley (1881) with the heading {"Trichogramma minuta, 

 N. Sp") but all of the first introductory paragraph was omitted 

 and also the first sentence of the second ; the figure was also 

 omitted. The latter was republished in Comstock (1879) and by
