This group reaches its greatest development in South America, where the species 

 of Lelaps are numerous, although as yet only a few have been described. 



The group is, I think, correctly placed in the family 3Iiscogasteridx. It shows 

 some affinities with the Cleonymidm, and with the Pteromalidx, through the subfam- 

 ily Diparinse. The two spurred hind tibi?e, however, separate it from the latter, 

 while other characters separate it from the Cleonymidse. 



The metathorax at apex is most frequently contracted into a neck, the usually 

 conically produced abdomen being attached to this neck by a short petiole. The 

 mesonotal furrows are complete ; the axill?e are usually approximate, although 

 separated at base of the scutellum, while the head, especially in the genus Lelaps, 

 resembles somewhat that found among the Cleonymidse, the eyes being large and 

 the occiput flat. 



My recently characterized gQnxxQ Apterolelaps \s from North American, and super- 

 ficially resembles Philachyra Haliday, a genus in the Eurytomidse.

4. Abdomen conically produced at apex, and usually ending in a prominent ovipositor ; second segment 



large, occupying fully half the surface, the third to fifth very short, the sixth and seventh together 

 conical, longer than half the length of the second. Lelaps Haliday (type Merostemis sodales Walk.). 



5. Abdomen conically produced at apex, the second segment not much longer than the third and fourth 



united, the fifth longer than the fourth, the seventh conically produced ; scutellum with a cross-furrow 

 at its apical third Neolelaps Ashmead (type N. hawaiiensis Ashm.).
