INSBCUTOR INSCITI^ MENSTRUUS 139 



stigmal, the proximal margin of this band straight, its distal 

 margin beveled off to the apex of the stigmal vein. Venation 

 fuscous, the marginal vein about eight times longer than wide, 

 the stigmal somewhat longer, long and slender, the post- 

 marginal barely developed. Oblique hairless line closed cau- 

 dad, not reaching by far the proximal margin of the fuscous 

 cross-stripe which is coterminous with the discal ciliation. 

 Club not much longer than wide, hive-shaped, narrower than 

 the funicle which narrows distad ; funicle, largest (longer down 

 one side than the other), much wider than long, 6 over four 

 times wider than long, shortest; pedicel very minute. Scape 

 greatly dilated. Hind tibial spur single. Frons moderate. 

 Cheeks shorter than the eyes. Scrobes not joined above but 

 distinct. Head lenticular, longer than wide. Club one-third 

 the length of the fiat funicle. On the fore wing a narrow 

 marginal naked space along the distal margin of the fuscous 

 marking. Scutellum more densely, finely scaly than the scu- 

 tum. Axillae separated by a very short carina. Scutum with 

 tolerably dense short pubescence. 



From one female on a tag in the U. S. National Museum, 

 labeled "Dactylopius. Adelaide, S. A., 16," but mounted with 

 what appears to be a dipterous puparium upon which it is 

 parasitic. From Arthur M. Lea. 



Type: Cat. No. 20884, U. S. Nat. Mus., the above specimen 

 and a slide. 



NEORHOPUS, new genus 



Female. — Differs from Rhopus in having the mandibles with 

 three small, acute teeth, the marginal cilia of the fore wing 

 absent and in the venation. Marginal vein somewhat longer 

 than wide, subequal to the postmarginal, the stigmal somewhat 

 longer. Differs from Psyiledontus Crawford in having the 

 postmarginal vein, in being nonmetallic and having the body 

 longer as in Rhopus. Ovipositor inserted somewhat distad of 

 the middle of the abdomen, the latter conical, somewhat longer 

 than the rest of the body. Thorax with a phragma. Axillae 

 narrowly joined. Caudal femur compressed, rather large. 

 Head round, the face inflexed. Frons broad. Cheeks shorter
