ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 349 



6. Scutellum with two longitudinal grooved lines ; hind wings acutely pointed ; front wings with a long 



marginal fringe Gyrolasia Forster (type Fteroplrix menes Walk.). 



Scutellum with/oM/- longitudinal gi'ooved lines ; hind wings not acutely pointed. 



Head and thorax smooth or nearly, at the most only sparsely punctate, metanotum smooth, 

 with a delicate median carina ; abdomen rotund or broadly oval, shorter than the thorax but 



wider Syntomosphyrum Forster (type Eulophus cyclogaster Katz.). 



Head and thorax shagreeued or punctate, as well as the abdomen ; metanotum punctate ; 

 abdomen rather long, cylindrical, the segments subequal Trichoporus Forster (partim). 



7. Scape of antennae normal, neither greatly thickened nor dilated 8 



Scape of antennae abnormal, enormously enlarged, or dilated ; antennae 9-jointed with one ring-joint, 



the funicle 4-jointed. 



Front wings with a long marginal fringe ; funicle joints short, moniliform. . . .Ceranisus Walker 



(type C. pacuvius Walk.). 

 Front wings with a short marginal fringe ; funicle joints longer than thick. Baryscapus Forster 



(type unknown). 



8. Antennae 10-jointed, with two ring-joints, the funicle 3-jointed, the club ovate, 3-jointed 9 



Antennae 9-jointed, with one ring-joint, or less than 9-jointed 10 



9. Abdomen ovate or conic-ovate, rarely, although sometimes, greatly lengthened and conically produced 



as in Hyperteles Tetrastichus Haliday (type Eulophus miser Nees). 



10. Antennae 9-jointed, with one ring-joint .11 



Antennae 8-jointed, with one ring-joint 12 



11. Front legs normal, the tibiae and tarsi long and slender ; pronotum not long, rounded before, hardly 



half the length of the mesonotum ; abdomen much elongate, conically produced, subcompressed, with 



u.sually a prominent ovipositor ; funicle joints much longer than thick Aprostocerus Westwood 



(type A. caudatus Westw.). 

 Front legs abnormal, much swollen, the tibiae short and thick ; pronotum large, transverse quadrate, 

 nearly as long as the mesonotum, the front angles a little rounded; body of abdomen oblong, de- 

 pressed, not longer than the head and thorax united, the ovipositor prominent but not longer than 

 half the length of the abdomen ; funicle joints short, not longer than thick, sometimes a little wider 

 than long Crataepus Forster (type C. agrisgranensis Forst.). 



12. Abdomen ovate, the ovipositor hidden. 



Antennae very short, clavate, the pedicel obconic, thicker and longer than the first two joints 

 of the funicle united, which are small, quadrate ; wings with a long marginal fringe. 



Pentastichus Ashmead (type P. xanthopus Ashm.). 



13. Mesonotum without a median grooved line 14 



Mesonotum with a median grooved line 21 



14. Species fully winged 15 



Apterous or subapterous. 



Pronotum long, conical ; antennae 9-jointed, inserted close to the mouth, the scape long, 

 broadly dilated towards apex, the pedicel and first funicle joint dilated, the funicle 

 joints 2-4 small, transverse, the club ovate, 3-jointed Melittohia Westw. 



15. Antennae 9-jointed with one ring-joint 16 



Antennae 8-jointed or less 20 



16. Front wings with a short marginal fringe, the hind wings not acutely pointed at apex 17 



Front wings with a long marginal fringe, the hind wings acutely pointed at apex. Gyrolasia Forster.
