74 GENERIC SYNOPSIS. 
abdomen with a short peduncle, spatulate; posterior coxe very large; hind 
tibize with a very long spine in both sexes. 
HEMIPTARSENUS Westw. ——— 3sp. H. fulvicollis Westw. 
Antennz long, simple in both sexes, 7-jointed, second joint small; third to sixth 
equal, oblong ; seventh smaller, ovate (inarticulate ?); abdomen ovate, depressed, 
acuminate at tip; wings ¢ abbreviated. 
DICLADOCERUS Westw. ————— 1 sp. D. Westwoodii Steph. 
Differs from Eulophus in antenne ¢ biramose ; se. 9-jointed, second joint small ; 
third and fourth longer, each emitting a branch ; fifth and sixth thicker, simple; 
the three last forming a mass. My vol. i. frontisp. f. 4. 
ELASMUS Westw. Awnrure Esenb. 1 sp. ul. flabellatus Fonse. 
Antenne ¢ with the third to fifth joints extremely short, each emitting a long 
branch, sixth long; ¢ 10-jointed, third and fourth joints annular ; sides of the 
metathorax in both sexes produced behind into a large concave plate. 
EULOPHUS Geoff: 37 sp. Wik. ul. pectinicornis Linn. 
Antenne ¢ 9-jointed, third, fourth, and fifth joints emitting a long branch at 

base; @ 3-jointed, simple; tarsi 4-jointed; stigmal branch long; abdomen 
depressed ; max. and labial palpi 3-jointed. Curt. 133. 
Obs. Mr. Walker also introduces into this genus my Dicladoceri, Euplectri, 
Hemiptarseni, and Stenomesii, together with 49 other species, forming 
nearly as many sections. 
Exacuestus Esenb. 
BDSM DIDO NSIS Evtoruus p. Esenb. 
his sp. Ful. Latreillet Curt. 
Subcostal nerve of the fore wing longer than a third of the wing; stigmal branch 
very short ; antennz simple, short. 
Obs. Dalman’s types of this genus are the species whose males have 3-ramose 
antenne, which being the typical Eulophi, Dalman’s name ought only 
to be considered as a synonym. Mr. Walker however retains it, placing 
in it my Closteroceri, Derosteni, Smaragdites, Omphale Hal., and 124 
other species, forming nearly as many sections. 
SMARAGDITES Westw. Exacuestus p. Esenb. 1 sp. Sm. admirabilis Westw. 
Antenne as long as the entire body, apparently 9-jointed; basal joint dilated, 
second short, third very small; the remainder long, filiform, with long hairs ; 
thorax ovate; abdomen longer and much narrower than the thorax, elongate- 
ovate. 
DEROSTENUS Westw. —M——— l1sp. JD. gemmeus Westw. 
Head large; antenne 9-jointed; fourth, fifth, and sixth joints broadest, hairy ; 
three terminal joints forming a small attenuated mass; collar very narrow ; 
abdomen smaller than the thorax, depressed ; peduncle long. 
CLOSTEROCERUS Westw. -———— 2 sp. Cl. trifasciatus Westw. 
Antennz 8-jointed; basal joint dilated at the tip, the remainder forming a de- 
pressed fusiform club; fourth joint rather larger than the third and fifth ; 
abdomen nearly sessile, ovate, depressed ; wings large. 
APROSTOCETUS Westw. —— 11sp. A. caudatus Westw. 
Antenne 8-jointed, second, third, fourth, and fifth joints equal, but gradually 
thickened ; abdomen elongate, sessile, twice as lomg as the thorax ; ovipositor 
exserted ; tarsi 4-jointed. 
OMPHALE Zail. 7 sp. O. Salicis Hal. 
Antenne 7-jointed, ¢ elongate, linear, verticillate-pilose, terminal joints equal ;
