19. Abdomen at the most with dorsal segments 1 to 3 incised at apical middle ; sometimes with only the 



fii'st and second incised 20 



Abdomen with dorsal segments 2 to 5 incised or emarginate at apical margin 25 



20. Second abdominal segment not as long as all the segments united 21 



Second abdominal segment as long as all the segments united 24 



21. Eyes neither especially large nor strongly convergent above (although somewhat convergent), the ver- 



tex not very narrow, the hind ocelli not approximate 22 



Eyes very large, strongly convergent above, the vertex narrow, the hind ocelli very approximate, the 

 front ocellus placed far anteriorly 23 



22. Frons with a deep A-shaped antennal furrow ; antenna; 13-jointed, ringed with white, inserted close to 



the mouth Idoleupelmus Ashmead (type I. annulicovnls Ashmead). 



Frons deeply grooved ; antennae 13-joinied, but not ringed with white, clavate, obliquely truncate at 

 apex from beneath, inserted on or near the middle of the face ; abdomen longer than the head and 



thorax united, the dorsal segments 1-3 incised at apical middle Macreupelmus Ashmead 



(type M. brasiliensis Ashmead)- 



23. Abdomen spatulate ; occiput with a buuch of deep black bristles behind the ocelli. 



Tineobius Ashmead (type T. citri Ashmead). 

 Abdomen long, oblong-oval ; occiput normal Ischnopsis Ashmead (type I. oplitlialmica Ashmead). 



24. Eyes convei'ging above ; antennae inserted on the middle of the face Lutnes Cameron 



(type L. ornaticornis Cam.). 



25. Scape long and more or less compressed ; postmai'ginal vein very long, the stigmal vein curved, not 



short Cerambycobius Ashmead (type Eupelmus cleri Ashm.). 



26. Wingless or subapterous 27 



Winged 29 



27. Metathoi'acic angles normal ; antennaj inserted only a little below the middle of the face, never close 



to the mouth border ; face without transverse furrows 28 



Metathoracic angles spined ; antennjie inserted close to the mouth border ; face with transverse furrows. 



Myrmecomimesis Dalla Torre (type Myrmecopsis nigricans Walk.). 



28. Abdomen with dorsal segments 2 to 6 not incised at apical middle Eupelminus Dalla Torre 



(type Urocryptus excavatus Westw.). 



Abdomen with dorsal segments 2 to 6 more or less incised or emarginate at apical middle (apterous 



forms) Eupelmus Dalman. 



29. Abdomen long, conic-ovate, oblong, or conically acuminate, as long or much longer than the head and 



thorax united, the dorsal flap always deeply incised at apical middle 30 



Abdomen clavate or spatulate, broadened behind, narrowed toward the base, not as long as the thorax 

 or shorter than the head and thorax united, depressed or flat above, the dorsal flaps not incised or 

 the incision is not very deep 33 



30. Ovipositor shorter than the body, usually shorter than the abdomen 31 



Ovipositor always longer than the entire body, usually very much longer 32 



31. Antennae inserted a little below the middle of the face, on or above an imaginary line drawn from the 



base of the eyes, rarely a little below it Eupelmus Dalman (type E. memiwmius Dalm.). 



Antennae inserted above the middle of the face, or at least never below the middle. 



Axillae widely separated at base of scutellum ; wings not short, the marginal vein long, the stig- 

 mal vein very short, the postmarginal long ; antennae 13-jointed Charitolophus Forster 



(type C. ccerulescens Forst.). 

 Axillae approximate ; wings short, somewhat narrowed ; antennae 9-jointed (teste Motschulsky). 



Cacotropia Motschulsky (type C echidna Motsch.).
