3433 Tiphia granadaensis sp. nov. 



Black, rather donsoly covered with white hair; the flagelluni of anten- 

 nae rufo-testaceous; centre of metanotum with two Iveels which converge 

 slightly at the apex; wings clear hyaline, the nervures and stigmas 

 black. Male. Length 5 mm. Granada, Nicaragua. 



Lower part of front, face, clypeiis and base of mandibles densely 

 covered with silvery pubescence; the front and vertex punctured, the 

 former more closely and not so strongly punctured, its base bordered 

 by a stout keel. Mesonotum sparsely punctured, most strongly in the 

 centre, the apex in the middle w'ith an oblique slope. Scutellum sparsely 

 indistinctly punctured. The central area on the metanotum is smooth, 

 the two keels at the base are slightly curved outwardly; in the basal 

 half is a stout keel, with a minute one on either side; on the sides, 

 inside the spiracles, is a double curved keel. Pleurae sparsely pilose; 

 the metapleurae bare, shining, irregularly longitudinally striated. Across 

 the apex of the petiole is a crenulated furrow; the base of the second 

 segment is depressed and striated; the apical segments are densely 

 covered with longish white hair. The fore tibiae and tarsi are testaceous. 

 The bassal abscissa of the radius has a short basal and a longer straight 

 apical curve; it is not much shorter than the second, the third is the 

 shortest and is roundly curved at the apex; the second transverse cubital 

 nervure is broadly roundly curved. The furrow on the sides of the meso- 

 notum is narrow and rondly curved. Palpi dark testa f'eous. Mandibles 

 blackish. The scutelhim is distinctly punctured, except the sides in the 

 middle; the postscutellum is more uniformly punctured. 



Comes close to T. testaceipalpis Cam. (Invert. Pacifica, T, p. 69), 

 having like that species two keels on the metanotum, if we do uot 

 count the half length keel on the basal half. 



ICHNEUMONIDAS - MESOSTENINI 



3465 Mesostenoideus bakerianus sp. nov. 



Black, the face, clypeus, inner orbits, the lower half of the outer 

 orbits entirely, malai space, the base of the prothorax, a broad band 

 on the edge of the pronotum, tegulae, a conical mark — the base trans- 

 verse — the apex narrower and rounded, scutellum except on the basal 

 slope, its keels, postscutellum, the sides of the metanotum broadly, the 

 marks covering the spines, tubercles, the lower half of the mesopleurae, 

 the mesosternum except the furrow, a large mark below the hind wings, 

 the lower half of the metapleurae and the apices of the abdominal 

 segments — the bands on the second and third broader than the others — 

 yellow. Legs pale yellow; all the femora l>xoadly black above, the tro- 

 chanters spotted with black; the fore coxae black below, the two post- 

 erior broadly black in the middle above; the apical joints of the four 

 fronttarsi black. Wings hyaline, the stigma and nervures black. 

 Antennae broadly ringed with white. Female. Length 12 mm.; terebra 

 4 mm. Chinandega, Nicaragua.
