hiUBFAMILY III. PFLKCINELLINiK. 



1897. PelecinellinfP, Subfamily III., Ashmead, Proc. Ent. Soc.Washington,IV.,p. 201. 



This subfamily is at present represented by a single genus, Pelecinella Westwood. 

 Three species have been described, all from Brazil, and these are the largest and in 

 some respects the most striking looking ( 'halcid-Hies known. 



The affinities of the group were discussed in my paper, '• ( )ii tlie ( icnus Peleci- 

 nella Westwood," published in 1897. 



Form very elongate ; pronotum verj' long, longer and narrower than the mesonotum, contracted in front ; 

 head with a deep frontal furrow; abdomen long, compi-essed, lanceolate, ending in a long ovipositor, and 

 lougly petiolate ; hind legs long, the coxa" long and cylindrical, the tibisB longer than the femora, very 

 gradually widened toward apex and terminating in two spurs, the tai-si slender, as long as the feraoi-a, the 

 first joint longer than Joints 2 oiniited ; stigmal vein very short, the marginal vein long, the postmarginal 

 longer than the marginal Pelecinella Westwood (type Ji. phantasma Wcstw.).
