This is probabh' but a form of fasciatum, having been referred to 

 as such l^y Griffini. Most of these females have the ovipositor 12 or 

 18 mm. long, but one specimen has it l)arel3' mm. This latter speci- 

 men, which agrees with ones named saltator by Dr. S. H. Scudder, 

 has the ovipositor straight while in the others it is a little curved. 



28. XIPHIDIUM STRICTOIDES, new species. 



FiTiuili' (male unknown). — Superticially resembling X. strictina 

 Scudder and in man}' respects structurally allied to it. 



Slender. Green or brownish. Fastigiura of the vertex narrow, 

 viewed from above narrower than the basal segment of the antenna-, 

 constricted before the tip, from an anterior view considerably and 

 gradually narrowing from above downward. In the allied species, 

 Kfrirfuiii, the vertex is much broader, ])eing as })road as the basal seg- 

 ment of the antenna? when viewed from above, and when viewed from 

 in front narrows abruptly- from al)ove downward, appearing triangular. 

 Pronotum with the lat(>ral lobes rounded-angulate below, the posterior 

 margin straight, without sinus. Dorsum of head and pronotum usu- 

 ally unicolorous, sometimes with the mediate line infuscated. Legs 

 unicolorous, all the femora unarmed; anterior tibia' with ♦> small spines 

 on each side below. Wings aborted; elytra about as long as the 

 thorax. api<'ally narrowly rounded, not, or barely, overlapping. Abdo- 

 men unicolorous. Ovipositor very long, much longer than the pos- 

 terior femora, nearly straight. 



Length, pronotum. 3.25-3.5 mm.; posterior femora, 15.5 mm.; 

 elytra, 3-3.5 mm.; ovipositor, 21 mm.
